C# Aurora / Re: C# Aurora Changes Discussion
« on: August 16, 2017, 04:54:13 AM »
Fleet 1 is part of Admin Command AA that is part of Admin Command B. Both have a command radius of 1.

Sol - B

1 jump

Alpha Centauri - AA

1 jump (2 jumps from Earth)

Barnard's Star - Fleet 1


Would Fleet 1 still get bonuses from both AA and B or only from AA? I think Steve's explanation says that the fleet doesn't have to be in-range of all admin commands, as long as the admin commands are in range of each other but I'm not sure.

Yes, would receive bonuses from both. Each link in the chain only has to be in range of the immediately previous link. With a network of command centres, you can spread bonuses across your territory.

Aurora Suggestions / Re: Semi-Official 7.x Suggestion Thread
« on: July 17, 2017, 03:42:49 PM »
Suggestion:

Simplify shipyard expansion.  Merge all the orders like "Add 1000 tons to capacity" orders into one "Add X tons to capacity" with a field to input exactly how many tons we want to add.

Edited to add this addition:
Do the same thing for adding slipways; let us add more than one at once.

March 2074
Attack on 70 Opiuchi

A raid on the 70 Ophiuchi system is ordered. A task force is assembled from the new cruisers Rio de Janiero, Vladivostok, Yokohama, light cruisers Bremen, Nashville, Osaka, and frigates Aldebaran, Alpha Centauri, Canopus, Deneb, Epsilon, and Vega. They arrive in-system on the 15th.

At 08:48 on 18 MAR 2074, four enemy contacts are detected bearing straight ahead; two 15,500 ton Anticosti-class, one 7,750 Protecteur-class, and one 7,750 Town-class.

At 09:30, the task force achieves ECM burn-through. Each cruiser shoots a full salvo of long-range missiles. The fleet reverses course, to try to maintain the range. At 5:32, the first salvo separates its submunitions. The first wave destroys one of the Anticosti-class cruisers, and causes serious damage to the second. The enemy continues pursuit. Several more waves of anti-ship missiles are fired, with no reply; although the surviving Anticosti-class shoots many down with point-defense missiles, it appears that the enemy lacks long-range antiship missiles. This allows the human fleet to pick apart and destroy the aliens ships at their leisure. The Protecteur-class destroyer is still intact, but deprived of power and drifting. The fleet takes up station at close range to the crippled vessel.

8 April 2074
The minelayer Hamburg detects a massive thermal contact of unknown origin at the Epsilon Indi-Gliese 1061 jump point. As per first contact protocol, Hamburg drops a message relay buoy and withdraws from the system.

28 April 2074
Communications are formally established with the Merskemre Aristocracy. Strikingly humanoid appearance with greenish-brown skin and reptilian features, their ruling oligarchs claim to be amenable to peaceful coexistence and trade.

Meanwhile, the alien vessel that was crippled in the 70 Ophiuchi system is boarded by marines operating off the assault ship Iwo Jima. No resistance is encountered; the boarding party finds the ship to be under completely automatic control, as suspected. The ship's computer, while heavily degraded, does confirm some theories of human xenologists: the federation that ruled this region of the galaxy millenia ago became engaged in a massive interstellar war, a war that they apparently lost. With their population centers, industry, and agriculture destroyed, their colonies and minor worlds fell into barbarism, starvation, and finally died out. Their surviving warships reverted to automatic control as their crews slowly starved. Their prime directive: to defend their space against any and all vessels of alien origin.

Unfortunately, shortly after capture, the destroyer explodes - either the result of battle damage, or some sort of self-destruct device designed to prevent capture. The salvage crew aboard takes heavy losses.

November 2075
Colonists arrive on Alpha Centauri-B II as the second wave of human colonization begins. A dwarf planet with gravity only one tenths of Earth, it is nonetheless a marginal terraforming candidate. The planet is named Tyre, after the ancient Phoenican city.

January 2076
Colonists arrive on Niflheim, 9th moon of the gas giant Asgard, formerly known Alpha Centauri B-I.  Niflheim has been in the process of terraforming for most of the last decade. It is considerably less dense than its sister, Jotunheim, with gravity 22% of Earth’s, but it also has abundant water ice.


February 2076
Capturing the precursor destroyer leads the admiralty to request a design for a vessel capable of boarding and capturing enemy ships during battle. The Anzio-class assault ship is designed to supplement and replace the older Valley Forge-class in some roles. Unlike the Valley Forge, the Anzio is capable of keeping up with and jumping with a fast task force. She will carry up to a battalion of marines or heavy infantry, and a battalion-sized or five company-sized drop ships for planetary assault or boarding actions. Six ships are planned.

Colonists arrive on Wolf 1061-A II. The planet is about the diameter of Earth, with gravity of 78%, covered in water ice, with a methane/ammonia atmosphere, tidally-locked to a dim red dwarf star. Terraforming operations have been underway for some years, and are expected to take another decade. The colonists name the world Medusa.

Earth's current survey fleet is reaching the end of their useful life as the boundary of explored space pushes the limits of their maximum range and endurance. The winning proposal for a replacement is a fleet of survey carriers, each carrying a complement of small grav- and geo-survey boats. Additionally, the Taurus-class survey ships might be pressed into service during time of war as light carriers.

Colonists arrive in the Wolf 359 system. Wolf 359 has two worlds that are decent terraforming candidates, Romulus and Remus. Romulus has a breathable oxygen/nitrogen atmosphere and earthlike gravity. Remus has 69% gravity and a nitrogen/methane atmosphere. Both planets are covered in water ice, but are too cold to easily support human life.

July 2076
A ruined alien colony is located on 70 Ophiuchi-B I.

September 2076
Gliese 832 III colonized. The planet has been undergoing terraforming for some time, and the atmosphere is now breathable. It is a “super-Earth” with gravity 1.17 times Earth’s, a strong magnetic field, and a day of 4.4 Earth days. The planet lacks a hydrosphere and is prone to severe tectonic activity. The colonists name the new world Sunrise.

Chapter 7
The Federation

Pictured is the state of the explored jump point network at the end of 2063. Several likely candidates for colonization are identified during this second wave of exploration; no fewer than 7 terraforming candidates orbit 70 Opiuchi, 1 in orbit of Wolf 1061, and two highly mineral-rich, terraformable worlds orbit Wolf 359.

At this point, over 250 million human beings call a world other than Earth home, across four different inhabited star systems. But the rapid pace of colonization has led to overcrowded and overworked colonists, and for nearly fourty years tensions have been steadily rising across human space. The UN forces in colonial space have not always been delicate in their handling of the colonists; reprisals and terrorist violence inevitably follow. Tensions soon become a crisis as Alpha Centauri and Acheron riot, calling out for home rule. The compromise solution, negotiated and finalized in early 2064, is to create a Federation of human worlds, with each planet having equal representation in a new Federation of United Systems. Each planet will have broad authority over its internal affairs, with a federal assembly deciding foreign policy, all space-based armed forces, and interstellar trade policy. The UNSF will form the backbone of a new United Systems Navy. The federation will not maintain a standing army; each world, or on Earth, each nation, will be permitted to maintain its own ground self-defense forces which may be called to federal service.

With internal tensions easing, the newborn federation ramps up for a second wave of human colonization.

22 June 2064
 A survey vessel is destroyed in the 70 Opiuchi system. EM emissions match those of the Lalande 21185 aliens. Some portion of the crew abandons ship, but their rescue beacon cuts out immediately afterward. With the navy restructuring and the combat effectiveness of their ships under question, no attempt at rescue or counterattack is made and the system is quietly declared off-limits.

August 2064
The El Paso-class salvage ship is designed in order to recover any usable technology from the remains of the battle of Lalande 21185. An initial three ships are laid down in August.

Meanwhile, the terraforming of Terra Nova is declared complete.

September 2064
Colonists arrive on Lalande 21185-A II. The planet itself is about two thirds Earth’s diameter, with gravity of about 44%. It has a very thin oxygen/nitrogen atmosphere, but lacks water and is tidally locked to a dim red dwarf. The settlers name the new world Horizon. Over two months’ journey from Earth, it is the most distant colony yet established.

June 2065
Terraforming of Pacifica concludes. Colonists arrive on Alpha Centauri-B I moon 3. The planet is earthlike in every respect, except for an average temperature of -95 degrees and being tidally-locked to its star. The gas giant it orbits was named Asgard during system exploration, and its moons given the names of the different realms of Norse mythology. This colony is named Jotunheim, after the domain of the frost giants in norse mythology.

August 2065
Pushing the frontier outwards will require a great deal of new infrastructure farther away from Earth than ever before, and the existing nuclear-engined tugs are now obsolete with the development of ion propulsion.

July 2067
Terraforming efforts finish on Hope. The United Systems are forced to delay their plans for expansion, due to shortages of minerals and funds. The focus returns to local development, industry, and infrastructure, including many new asteroid mining facilities.

August 2067
A ruined alien settlement is detected on Procyon-A III Moon 10, later identified as belonging to a race known as the Elric Commonwealth. Earth xenologists believe now that this region of space was home to a confederation of multiple species that spanned many star systems, but died out millenia ago after some sort of war or internal catastrophe. The exact cause remains unknown. The Sol system is centrally located between the three systems with confirmed alien presence, so must have been a hub of interstellar transit. No alien presence or interference has yet been detected in Sol, despite widespread conspiracy theories.

March 2070
Plans are finalized for the first class of ion drive warships. The Vega class will serve as a fleet escort, and to show the flag in the colonies. It is faster, more survivable, and better-armed than the Sirius class it will replace, despite being 25% smaller.

Due to continuing budget and resource shortfalls, four of the oldest Sirius-class frigates, Sirius, Jupiter, Dragon, and Arrow, are decommissioned as construction begins.

August 2070
The Portland class will be the United Systems Navy's frontline anti-ship combat vessel. Due to improved jump drive technology, the philosophy of separate jump ships accompanying task forces will be abandoned, in favor of combining both roles into a slightly larger vessel. New USN doctrine is that a jump drive will distinguish all capital ships; each capital ship will be able to jump itself and any escorts. Due to the low numbers of cruisers initially planned, this will be less expensive overall than a separate jump cruiser.

The Portland class is considered a great advance over the Dunkirk class. The initial design kept the 12,000 ton mass of the Dunkirk, and was increased to fit a jump drive without sacrificing weaponry or armor. Survivability, sensors, fire control and electronic warfare capabilities are all far ahead of the Dunkirk class. Due to the relative effectiveness of point defense fire vs. anti-missiles seen at Lalande 21185, anti-missile stores have been reduced in favor of additional kinetic armament. Her main armament will be four large-diameter missile tubes. This will allow the class to deploy mines, long-range sensor buoys, and survey probes in addition to anti-ship missiles. Her standard loadout will be 16 multiple-warhead missiles, each with four independent submunitions themselves more than twice the yield of existing anti-ship missiles.

The 2070 naval procurement budget leaves a little left over for experimentation - the result of which is the Bremen class. Inspired by the wet-navy gun cruisers of the mid-20th century, the Bremen class is designed to screen and provide close range area defense for a task force against fighters, drones, and missiles. The Bremen class represents a shift away from a pure missile force to a mixed missile/laser armed fleet, mostly due to the time and cost involved in maintaining a large supply of missiles. An initial three ships are ordered.

As the frontier will continue to grow, the United Systems Navy's plan for defense of the Federation's colonies is to forward-deploy frigates for missile defense and patrol, and squadrons of fast attack craft for the anti-ship role. Capital ships will be home-ported at Earth, thus minimizing the maintenance infrastructure required. Orbital maintenance facilities will have to be constructed at colonies and key points throughout Federation space.

Chapter 5

The Battle of Lacaille 8760
28 September 2060
The order goes out: Task Force 14 will proceed at once to the Lacaille 8760 system. Once in-system, they will sweep the system for alien activity. If contact is made, they will attempt communication and initiate no hostile action, although the commander is authorized to use any force necessary to ensure the safety of his task force, at their discretion.

The force will consist of the Dunkirk-class cruisers Dunkirk, Gettysburg, Jutland, Kursk, Waterloo, and Ypres, the Orion-class jump cruisers Auriga and Hydra, and the Sirius-class frigates Achilles, Apollo, Arrow, Avenger, Boxer, Brilliant, Broadsword, Cleopatra, Dragon, Juno, Jupiter, Leopard, Lynx, Minerva, Scylla, and Sirius. The fleet oilers Ontario, Cyclops, and Vulcan are tasked for underway replenishment.

At best speed, Lacaille 8760 is only 11 days from Earth; determining the nature of the anomalous contact and alien sighting is seen by the UNSF admiralty as a high priority to ensure Earth’s safety. The fleet has spent years preparing for combat, and now the time has come for their first patrol outside of the Sol system under real combat conditions.

10 October 2060
In position at the Lacaille 8760 jump point, task force commander Captain Guo Qing Hui detaches her replenishment ships, before squadron jumping the Auriga and Hydra, escorted by Avenger, Boxer, Lynx, and Scylla. Once the rest of the fleet is safely through the jump point, she detaches her frigates to screen the main force in a hexagonal configuration, with two rings at intervals of 350,000 km, the maximum range at which they can reliably detect enemy missiles. The task force gets underway in the direction of the last sighting of the alien vessel.

12 October 2060
The UNSF crews, while well trained, have never seen combat. The mood aboard ship is light and jovial, with most of the crew and officers treating the patrol as just another exercise. While rumors have been circulating the fleet about the sighting in Lacaille 8760, most have dismissed them. Even those who know the reason for the patrol don’t believe anything will come of it; if an alien ship was sighted, the system is devoid of planets – surely they must have moved on?

Then, after 34 hours in system, all hell breaks loose. Sensor operators detect 36 contacts of approximately 750 tons, bearing straight ahead and closing at a speed of 10,666 km per second. The contacts are assigned the codename “Barnard” by the tactical computer. The fleet reacts swiftly and professionally, as battle stations is sounded. The task force commander takes immediate evasive action, reversing course, and makes the judgement call that this is almost certainly a hostile response. For the preservation of the task force, she orders her fleet to engage.

As they are responsible for fleet defense against fast attack craft, the destroyers open up first. But the anti-ship missiles they engage with are only slightly faster than the enemy, so most of the first salvo misses. Those that do hit seem to do little to deter the advancing vessels. The Dunkirk-class cruisers then open up with their own anti-ship launchers; as the sound of the missiles leaving their launchers reverberates through each cruiser, the reality of the situation sets in for the men and women aboard.

The second salvo is more successful, with a higher hit ratio, and one enemy vessel is destroyed and another crippled by a secondary explosion. Sensors show the vessel as venting some sort of fluid into space.

With the enemy now closing to within 6 millon kilometers, those ships equipped with the latest generation of Barracuda anti-missile open fire with those.

By 3 million kilometers, the entire fleet is shooting everything that they can throw at the advancing vessels. Slowly their numbers are whittled down, but they keep closing the range in the face of dozens of anti-missiles. The final vessel is destroyed less than 200,000 km short of the frigates Apollo and Cleopatra.

After dispatching any disabled stragglers, the commander is able to take stock of her situation. About 25% of the fleet’s missiles have been expended. No damage or casualties have been reported. Bizarrely, what remains of the enemy doesn’t register as metallic – the sensors can’t make heads or tails of it. The  36 enemy contacts have been reduced to a cloud of vapor and what appears to be some sort of organic material. But the captain is not a scientist, and she orders the fleet to resume its original course.

24 November 2060
After almost a month on patrol since the battle, Captain Guo Qing Hui is close to declaring the system clear of hostile contacts. But during one final sweep, the fleet detects a massive active sensor contact in the vicinity of the star, near where it was originally reported. She orders the fleet to close within active sensor range.

Upon closing in, there can be no doubt that the vessel is the same contact reported five years earlier. Furthermore, the drive signature matches that of the small craft that were previously destroyed. This thing, therefore, must be some sort of mothership. She is authorized by fleet command to engage it.

But the strange vessel is protected by an energy shield too strong for even all 15 cruisers and destroyers combined to bring down, at least from range. Shortly after the first salvo lands, a second wave of 20 Barnard-class contacts appears on the screen, confirming the larger vessel to be a carrier or mothership of some sort. The captain orders her escorts to rejoin and maintain a tight formation as they allow them to close within anti-missile range. Once again, the enemy are stopped, but only just short of the fleet.

With the enemy attack wave stopped, the captain orders her fleet to close to 2 million kilometers, so that all armament may be brought to bear. The waves of anti-missile and anti-ship missiles begin to have an effect, but barely. The captain decides to close in even closer, to achieve even higher saturation. At 150,000 km, the missiles start to do real damage, with a more than one secondary explosion appearing on the scope. But the shields are still regenerating, so once the contact’s active sensor ability is knocked out, they close even closer, to less than 10,000 km, to engage point-blank with their secondary railgun armament.

At such close range, it is just barely possible for a ship’s onboard visual scopes to resolve the 60,000 ton vessel. And what they see is monstrous – a hulk of apparently living matter, writhing and scored by hundreds of missile impacts. It’s not just venting fluid – it’s bleeding. Without its energy shield, half a minute of railgun bombardment is all it takes to blast the entity apart.

After the battle, the remains are analyzed, but the analysis raises more questions than answers. Their means of propulsion and ability to generate energy fields cannot be explained. The scientific consensus is that such a species could never have evolved naturally in deep space. Somehow, these beings were engineered. But by whom, and for what purpose? The only thing that is certain is that they did not originate from Lacaille 8760. While not officially named except with a numeric designator, throughout the fleet, the Lacaille 8760 entities become known as the “Star Swarm”.

The crews of the task force, on their return to Earth, receive a hero’s welcome. 23 year old CDR Arina Yefimov, C.O. FFG Cleopatra, is singled out for heroism, destroying four enemy vessels while maneuvering at point-blank range with the enemy. She is awarded the Sol Cross, the UNSF’s first combat decoration.

Analysis of the battle raises some questions about the UNSF’s ships and doctrine. 208,000 tons of Earth spacecraft took on 102,000 tons of space monster and won without casualty, but only prevented them from closing by the narrowest of margins. The biggest point of criticism is the missiles used; the fleet was mostly equipped with a mix of current- and previous-generation missiles, and the previous generation of anti-missile has only a 2.1 million km range. Several salvos were wasted after being fired from beyond their maximum range due to mid-battle confusion. The anti-ship missiles used did not have a uniform speed, giving the enemy’s shields time to regenerate, and the rate of fire was too low. Neither AMM or ASM was wholly effective against the enemy fast attack units. Furthermore, a single battle depleted almost the entire supply of modern anti-missiles.

Railguns proved extremely effective against a disabled target, but would have been too short-ranged to be useful against a “boom and zoom” attack. The fleet’s detection and early warning systems were inadequate; the mothership should never have escaped detection on the initial pass through the system. One final criticism would be that the Sirius-class frigates, being designed as patrol vessels, lack the speed to maneuver with fleet assets. Future escorts should be faster than the ships they’re escorting.

On the positive side, the use of intermediate-resolution sensors and fire controls proved crucial. Having an extra fire control system allowed the cruisers and destroyers to engage enemy fast attack units with both short- and long-range missiles. Crew performance was excellent, and the fleet-wide focus on training over the last several years made a great deal of difference. The presence of replenishment oilers capable of keeping up with a task force at full speed was also a major asset.

April 2051
While surveying the Lalande 21185 system, the geosurvey ship Neptune is fired upon and destroyed by an unknown alien force.  Some of the crew escape in life pods, but no rescue is possible or attempted.  Fleet command is not informed until the rest of the survey group returns to Sol some two weeks later.  All at once, humanity is confronted with the knowledge that not only is man not alone in the universe, but that there exists a hostile alien power on Earth’s doorstep.

Public reaction across Earth and her colonies is one of near panic.  The UN security council makes the immediate decision to arm for war.  The current fleet of Sirius-class escorts were never designed to stand toe-to-toe with an enemy fleet.  They entirely lack long-range sensors and standoff weaponry.  A new fleet will need to be constructed.  A moratorium on exploration is imposed until the threat can be assessed and dealt with.

June 2051
The first mobile terraforming bases are constructed; terraforming of the moon begins.  The Sirius-class ships begin refitting with newly-developed nuclear pulse engines.  No longer euphemistically labeled “patrol vessels”, they are now designated as guided missile frigates, as their only suitable role will be to serve as screens and escorts for larger warships yet to be built.

12 March 2055
A J-100 jump scout is sent to investigate the anomalous contact in the Lacaille 8760 system.  An initial scan of the system reveals nothing. On reaching the vicinity that the contact was reported, the ship detects an enormously powerful electromagnetic contact.  The scout avoids detection and manages to fall back to the Ross 154 jump point.  First contact is attempted using message buoys to disguise the entry jump point, but no communication received.  The system is declared off-limits. 

Elsewhere, six new GEV-100 class survey ships are ordered.  The Antares class has served admirably, but they are now over 20 years old and due for refit or replacement.  The decision is made to replace them with a much smaller vessel equipped with passive sensors and their own jump engine.

The first three Dunkirk-class cruisers are commissioned.  A J-100 scout ship on a reconnaissance mission to the Lalande 21185 system detects a massive thermal contact in orbit of Lalande 21185 II.  As Lalande 21185 II is apparently barely hospitable to life, it is thought that the planet may be some sort of forward base.  The UN security council has been deadlocked on the issue of whether to try to take the system, due to the risk that an attack may provoke some vastly superior alien power.  For now, Earth's space forces will focus on training and reconnaissance.

Three Valley Forge-class assault ships are laid down: Valley Forge, Saipan, and Iwo Jima.  It has been considered that an attack on Lalande 21185 may involve ground combat; this requires some method of transporting soldiers and their equipment into battle.  The Valley Forge class is an assault ship capable of transporting an entire brigade  of mobile infantry and has a hangar deck for dropships or landing craft.

July 2055
Colonists arrive on Gliese 682 II.  The planet is a frozen world almost entirely covered with water ice.  It has a thick oxygen/nitrogen atmosphere and gravity of 1. 7 g.  The planet is approximately twice the size of Earth, and tidally-locked to its red dwarf sun.  The colonists choose the name Pacifica for their adopted homeworld.

October 2055
The Antares class geosurvey ships are decommissioned as the first GEV-100 class ships enter service.

October 2056
Survey ships are able to recon the Lalande 21185 system, finding no sign of alien presence beyond the second planet.  Despite being extremely minerally rich, there is no sign of mining activity.  Fleet intelligence surmises that the alien presence on Lalande 21185 II may be a forward operating base or outpost.

January 2057
A J-100 jump scout is lost with all hands while on a recon mission to Lalande 21185. It manages to close within 13.8m km of Lalande 21185 before being detected. While tragic, it does establish a useful baseline for how far away FAC-size craft must be able to engage.

June 2057
For the last six years, the UNSF's focus has been entirely on preparing for the possibility of interstellar war.  25 Sirius-class frigates are now in service, along with six each of the Dunkirk-class cruisers and Fearless-class destroyers.  But there's been no sign of intrusion from Lalande 21185, or any sign of activity at all in the system, despite regular patrols by small craft.  Colonization has been advancing rapidly, with 80 million people now living on Mars, and over 70 million on the moon; 17 million more call Alpha Centauri home, and another million people have settled on Pacifica.  Terraforming of the moon is rapidly progressing as well.  The colonies have almost reach the point of being self-sustaining; the next step in the UN's development plan is to set up their own domestic industry; to support this aim, the UNSF's spacelift division will require significantly larger transport capability.  To that end, the Minsk-class of freighter is developed:

Three ships are ordered in 2057.

In order to project power beyond the jump gate network, the UNSF requires a jump ship.  The Orion class is based on the Dunkirk class, but with the long-range sensors and most of the anti-ship armament deleted to make room for a jump drive.  Three ships are laid down: Orion, Auriga, and Hydra.

August 2057
A million settlers arrive on V577 Monoceri-B II.  The most inhospitable planet yet colonized, it has a very thin oxygen/nitrogen atmosphere and gravity 45% of Earth's, but lacks a hydrosphere or a magnetic field.  The colonists name the new world Acheron.


Ten years after the first FTL jump, exploration has stagnated as the UNSF focuses on building up its military strength and developing the existing colonies.  Several jump points are mapped but unexplored.


Alpha Centauri and Gliese 682 are home to human colonies; the Ross 154 jump point is just outside Earth's orbit and the system has several gas giants rich with Sorium, making it a natural location for a fuel harvesting base.

Chapter 2

2038
Scientists theorize that Trans-Newtonian technology allows the stabilization of natural wormholes to allow faster-than-light travel between points in space.  The work is initially kept secret.

2039
A method of detecting these wormholes by studying the interaction of large gravitational fields is devised, while scientists begin work on a “jump drive” capable of traversing them.  The wormholes themselves become known as jump points.

2041
The Aries is launched as a testbed for this gravitational survey equipment.  Almost immediately, a stable jump point is detected between the orbits of Earth and Mars.  Four more ships are commissioned, and soon, a total of six such jump points are mapped throughout the solar system.  Knowledge of their existence is kept highly classified.

2042
With the burgeoning numbers of civilian TN spacecraft and increasing incidents of TN technology being reverse-engineered, it is seen as only a matter of time before a nation-state, pirate, or terrorist organization exploits TN technology for nefarious purposes.  Privately, the decision makers who know of the theoretical possibility of interstellar travel are also wary of the possibility of a hostile alien power.  After much deliberation, the UN votes to amend the Outer Space Treaty to allow the construction of armed spacecraft to patrol the spacelanes.  The UN Space Agency is reconstituted along paramilitary lines into the United Nations Space Force, with the permanent members of the UN security council all directly contributing personnel and material.  The force’s mission is singular: protect Earth and her colonies from spaceborne threats.  RADM Laverne Muranaka is named UNSF commander.

2044
The design of the first armed TN spacecraft is finalized.  Their primary mission will be to patrol the space lanes to prevent piracy and terrorist action.  They have a secondary missile-defense role.  Four ships are initially ordered: Sirius, Arrow, Dragon, and Jupiter.

April 2046
Trans-Newtonian technology has revolutionized Earth's industry.  While not a "post-scarcity" society by any means, the TN revolution has solved some of the most pressing problems of the 21st century: clean energy, climate change and the availability of water.  While the benefits haven't been universal and conflict hasn't been eliminated on Earth by any means, the great powers of Earth agree to renounce their first-strike ability and place Earth under the aegis of an internationally-run, global missile-defense network.  The possibility of FTL travel persuades the more paranoid among them that such a system is necessary to guard against an extraterrestrial threat.  Work begins on four Missile Defense Bases.  Each base is designed to protect near-Earth space from spaceborne threats.  Meanwhile, an automated mining colony is being established on Mercury.

21 November 2047
JSC Hercules, upon transiting to the Lacaille 8760 system, detects an anomalous object in orbit around the star.  The red dwarf lacks any natural satellites.  Sensor readings indicate the object is made of an unknown material.  What is the object? Is it a starship? Where did it come from? Lacking any answers, but faced with the strong possibility that the object is artificial, fleet command decides to classify the report until such time it can be more thoroughly investigated.

After the discovery, the security council authorizes another eight Sirius-class ships: Alacrity, Amazon, Avenger, Broadsword, Charybdis, Daring, Leander, and Leopard.

July 2049
For the past decade, scientists have postulated that Trans-Newtonian technology could enable the terraforming of the moon and Mars.  An installation in lunar orbit could process the lunar regolith into its component elements and release the oxygen, creating a breathable atmosphere.  Furthermore, discovery of a gaseous compound with excellent greenhouse properties - and nontoxic in any practical concentration – would allow temperature stabilization at a level compatible with human life.  Constructing such an installation would be no mean feat of engineering, however, and terraforming on a time scale above centuries would require many such installations.  After a lengthy design process, work begins on two such terraforming bases.

Settlers arrive on Alpha Centauri-A III and IV, Earth’s first extrasolar colonies.  Alpha Centauri-A III is a relatively Earthlike planet two thirds the size of Earth, with an average surface temperature of -21. 1 degrees, gravity of . 68 g, an Earthlike magnetic field and a nitrogen atmosphere thick enough to walk outside with only an oxygen mask.  It has a 22 hour day, 327-day year, and an extreme axial tilt of 66 degrees that causes extreme seasonal variations.  However, it lacks a hydrosphere.  After arriving, the colonists decide to name the world Terra Nova – New Earth.

Alpha Centauri-A IV is colder, has a very thin nitrogen/oxygen atmosphere, gravity of . 48 g, and a trace magnetic field.  It also has a 22 hour day, 5 degree axial tilt, and plentiful water in the form of ice over 41% of the surface.  The colonists name their new world Hope.

A third world, the third moon of the gas giant Alpha Centauri-B I, is marked as a candidate for future colonization.  It has gravity, magnetic field, and a breathable atmosphere almost identical to Earth, but is too cold to make current colonization practical.

Setup
Starting year: 2018.  Standard conventional start.  I didn't go to the trouble of messing with population size or add a neutral NPR, so we'll have to accept that 500 million isn't the 'real' population of Earth, merely the fraction that is industrialized and participating in the labor force.  Real stars, difficulty is at 150%, NPR chances at 60/90 (I never seem to get NPRs in real starts games. . . ), no starting NPR.  Spoilers on (no invaders).

2018
The United Nations Space Agency is formed, part of a renewed multinational push towards space exploration.  At its inception, the agency’s budget and scope is limited to serving as go-between with  participating national space agencies on several international exploration missions.  Mohammed Crumby named first agency head.

May 2022
Dr.  Hung Metheney’s research team publicizes their discovery of several stable trans-uranium elements with exotic matter properties.  Their breakthrough ushers in what will become known as the era of “Trans-Newtonian” science.  Their work will have far-reaching implications across all fields of science and industry.  The first visible application of this discovery is an experimental device the team calls an “intertial nullifier” - a device which uses TN elements to generate negative mass and neutralize most of an object’s inertia and the effects of gravity on that object.  The discovery makes conventional orbital rocketry obsolete overnight. 

The scientists and engineers responsible for the discovery insist that the technology be used for the betterment of all mankind, and given its obvious potential military applications, it is too powerful a force to leave in the hands of any nation.  They zealously guard the details of their research until a multinational organization is set up to oversee its application and distribution, to prevent reverse engineering.  One of the consequences of this policy is that the UNSA is given exclusive rights to the technology for space exploration.  This forces the last holdouts among the national space agencies to join the UNSA, which will form an umbrella organization managing the exploration and exploitation of the solar system using Trans-Newtonian technology.

December 2023
The first spacecraft built in orbit using TN technology is launched.  The Armstrong, and her sister ships Gagarin, Glenn, Shepard, and Tereshkova are the first manned vessels operated by the UNSA.  While TN technology gives them unprecedented range and endurance, they rely on conventional electrical propulsion.  While very fuel-efficient compared to chemical rockets, this means they devote more than 3/4ths of their mass to the drive section.  The equipment and crew size required necessitates a total mass greater than a fully-fueled Saturn V rocket.  The mission of these five spacecraft is to survey the inner solar system, scouring planets and asteroids for the exotic elements Earth will need to fuel its nascent trans-Newtonian industry.

For the last two years, the UNSA has been planning for the exploration and eventual colonization of the moon and Mars.  To support this, plans are drawn up for a fleet of transport and colony ships.  With Trans-Newtonian technology, the round trip to Mars can be made in a matter of weeks rather than years, and there is no requirement for a favorable launch window.

Trans-Newtonian industry is finally making construction of a permanent lunar colony practical, but do so will require a fleet of transport and colony ships.

2028
Renewed interest in nuclear propulsion leads to the first practical nuclear thermal rockets built to take advantage of TN materials.  This renders all existing spacecraft obsolete, but also opens up the outer solar system to exploration.  The first spacecraft to use atomic propulsion is the freighter Prospero, followed by the colony ship Phobos.  Ten Prospero-class freighters and five of the Phobos-class will be constructed in all.  The Hyperion- and Ganymede-class ships will soldier on for five more years, servicing the lunar colony, but are then scrapped once the initial wave of development is complete.

Refuelling Changes

In C# Aurora, refuelling is no longer instant and ships without specialised equipment cannot exchange fuel in space. A ship can only refuel at a Spaceport, a Refuelling Station, a ship with a Refuelling System or a base with a Refuelling Hub.

A new technology line - Refuelling Systems - provides the basis of the rate of refuelling and allows ships to mount systems to refuel other ships. The baseline system (Refuelling System: 50,000 LPH) sets the racial refuelling rate at 50,000 litres per hour and allows the use of the first ship-mounted Refuelling System. There are ten further steps in the tech progression with the highest tech system allowing refuelling at 500,000 litres per hour.

Spaceports, Refuelling Stations or Refuelling Hubs will always use the highest tech refuelling rate and can refuel an unlimited number of ships simultaneously. However, the ships being refuelled must be stationary.

Spaceports have doubled in cost to 2400 BP but can now be moved by freighters. They are equal to four research facilities for transport purposes (or 80 factories). They retain their existing bonuses to loading and unloading cargo.

Refuelling Stations are a new installation with a cost of 1200 BP. They do not require workers and can be moved by freighters. They have a transport size equal to 10 factories. Essentially, they are a cut-down version of a spaceport intended to facilitate refuelling in forward areas, transferring fuel from the surface of a planet to the waiting ships. They have no bonuses for loading or unloading cargo.

A Refuelling Hub can be mounted on a ship. It is a commercial system with a research cost of 10,000 RP, build cost of 2400 BP and a size of 100,000 tons. In practical terms, this is likely to form part of a large, deep-space station, due to the size and cost, rather than being deployed on tankers that will accompany fleets

A Refuelling System is 500 tons and has a cost ranging from 10 BP to 100 BP, depending on the tech level. A ship with a Refuelling System can refuel a single ship at once, so will take some time to refuel a whole fleet, although this will improve with higher technology. At the early tech levels, the Refuelling System can only be used if both ships (tanker and target ship) are both stationary. Another new tech line, Underway Replenishment, allow the refuelling to take place while both ships are in the same fleet and underway. Priorities can be set for the refuelling order when multiple ships are involved. The first Underway Replenishment tech allows refuelling at 20% of the normal rate (2500 RP), rising to 100% with the highest tech (40,000 RP).

Refuelling order types will be adjusted to deal with the new requirements. Fuel will be transferred during each movement increment as time passes until the target ship has full tanks. I may add some other options regarding partially filling as well.

I will be adding some rules along the same lines regarding ordnance transfer.

Area Defence shoots at any missile inside BFC range if they "stop" in that increment - if they just pass through the area inside the 5 seconds, then they are ignored.

Final Fire shoots at all missiles about to hit any ship in the same location.

Final Fire (self) shoots only at missiles about to hit the shooting ship itself.

So if you have PD ships with very long range lasers, they can be used in Area Defence mode. Most PD is best to be kept at FF mode. If you have some PD in high value targets, those might be worth it to keep on FF(self) so that they save their shots to defend themselves.

This is correct, except that Final Fire shoots at all missiles about to hit any ship within the range you specify (limited by the max range of the PD weapons).

Yes, in fact, I still use it myself. The basic propulsion math mechanics behind Aurora haven't changed, and I figure they won't in a long time, so this should stay fairly up to date.

You might also be interested in this thread: http://aurora2.pentarch.org/index.php?topic=7647.0
...where 2 other members here submitted similar sheets that instead solve for either highest speed on a desired range and mass designation, or minimum mass for a wanted speed and range combo. So with mine, which solves for range on wanted speed and mass, you have all 3 situations covered.

I have all 3, and use all 3, but I wanted to merge them into one super sheet for long. Problem is, the other two are more advanced, as they use VBA custom programmed commands, which I can read and understand, but not write myself, and I simply don't feel like learning VBA just for this purpose.

I think it would just mean an increase into the already heavy resource hog that is the civilian sector of ships. You really only need a single TG for any mineral transportation that is 1-2 jumps away from Sol, with a single colony set up as a "system capital" all other colonies make use of mass drivers to ensure the capital has a steady stream of minerals arriving. Then set up a set of orders for a TG that does a circuit of all your extra sol capital planets, at each one it loads up on minerals then makes a stop back to your empire capital to unload and refuel before setting off to the next stop. Add to that a tick in the cycle box and you have a transport system you can forget about entirely. If you decide to increase/decrease the amount of mining you are doing in the circuit you simply to a quick check and adjust the speed of the TG so that you minimise the amount of time spent with a less than full load.

In my current campaign I have some 30 odd colonies at present, these are spread out between Sol and 6 systems that are located a single jump away. However I am only using a single TG comprised of 2 freighters to keep the flow of minerals to Earth constant. A jump gate on each point in and out of Sol and liberal use of mass drivers in the systems has meant my growth is only limited by my own desire of how fast I want to mine these systems, anytime I require an increase I simply ship out (using civilian contracts) a few more auto mines and mass drivers. But the actual act of bringing minerals back to Earth is for all purposes fully automated using my own vessels.

The added benefit of this is that you "system capitals" then have a stockpile of minerals build up between each transport trip, this way they can slowly start to develop their own set of facilities etc and prepare for the time when you are looking to expand your boarders and thus need fuel and maintenance depots further out from the empire center. While you can set up civilian contracts for facilities at present, I think doing this for minerals would be something of a logistical nightmare as you need to keep going back to them. If it were something a civilian ship did automatically without input then you run the danger of having colonies that have an empty mineral stockpile which you now have to try to grow.
