Title: Multi-Purpose Frigate Concept, Minuteman Class Frigate
Post by: xenoscepter on July 18, 2020, 06:56:23 AM

 - A concept design for a multi-role missile Frigate. This design lacks speed, defense and mounts an inefficient array of missiles, but what it lacks in specialization it makes up for with robustness and tactical flexibility. While at first glance the spread of Missile Fire Controls will seem excessive, it is important to note that this design emphasizes chooses the right missile for the job. Hence, each spread of four Missile Fire Controls has a different resolution. Empty missile stages filled with Submunitions and set to a separation range of 0 km are used as "Canisters" for the design, allowing it to function as an AMM, Anti-Fighter, or capital Ship Killer.

 - Built using Composite Armor and Ion Engines, with Active Sensor Strength of 10 and Passive Sensor Strengths of 5 in both categories, this ship is far from high tech. A fuel consumption tech of 0.8 is barely nominal, while 4x warhead tech and an agility tech of 48 per MSP make for barely acceptable missiles. No engine power techs means that the missile designs presented were locked to 200% boost, and as such are quite slow. Gamma Shields and matching Shield Regen tech allow the ship to furnish itself with a modest passive defense screen, while 3 layers of Armor help it to tank lighter blows. A range of 8.1 billion km round trip is nothing to sneeze at, however, and the 57.6 PPV is excellent for a functional warship of this size. The launchers alone constitute just over 40% of this ship's mass!

 - It's not without significant vulnerabilities, but it's relatively cheap and very flexible. You could use it to survey with GeoProbes during peacetime and the 16 massive Size 24 Box Launchers give it great throw weight for such a little ship. The ability to load up against a variety of threats with the Canister rounds further extends the utility of this ship, and with such big launchers it can even be used as a minelayer when it gets old and outdated. The Active Sensors and Missile Fire Controls together amount to 4.8 BP worth of cost, so with a fairly simple refit the range of the launchers can be greatly extended. This allows for periodic upgrades that only require a refit of the sensors, fire controls and new ordinance to make the ship much more relevant again.

Minuteman Missile System:
 - A series of missiles designed for use with the Minuteman Class Frigate. The Minuteman I System is built around Canisters of submunitions, allowing each launcher to fire one "salvo" of the desired type of munition. SLASM denotes a "Space Launched Anti-Ship Missile", SLAMM denotes a "Space Launched Anti-Missile Missile", SLAFM denotes a "Space Launched Anti-Fighter Missile", and SLMPM denotes a "Space Launched Multi-Purpose Missile". The SLMPM Canister is the 'principle' munition of the Minuteman Class, and is meant to be used against a variety of targets. The MIRV is a special case among the Minuteman I System, as it is designed to be fired at a planet only when the Point Defense systems have already been neutralized.

 - The Minuteman I MIRV can be considered as a terror weapon to use against a helpless target rather than a tactical one. The Minuteman II System is a stand-off system designed to offset the Minuteman Class' relatively poor engagement range. The SLASM is designed around hitting other ships equal to or above the Minuteman's own weight, while the SLAPT is a "Space Launched Anti-Plantary Torpedo", and should be considered a long range tactical nuke and employed as such. It is worth noting that the SLAPT does only about a third of the damage of the MIRV, while also having only a third of the fallout. Both instances of the Minuteman II System use Active Sensors and waypoint fire as their primary method of engagement.

Title: Re: Multi-Purpose Frigate Concept, Minuteman Class Frigate
Post by: Jorgen_CAB on July 18, 2020, 08:11:20 AM

I find this a pretty cool concept, something I have tried before. The only real issue was that I had to manually fire AMM canisters as the auto system would not understand there are multiple AMM in each one. I also normally used two types of launchers as I recall, typically a size 6 and a size 12 launchers and the distribution was commonly 1/3 size 6 and 2/3 size 12 or something like that.

The smaller launcher would generally hold AMM and Anti-craft missiles but could also hold a small medium range cruise missile. The larger launcher cold then fit allot more varied designs.

In C# I think that these kinds of ships are even more viable as if you keep the frigates small you can easily bring a decent fleet tender vessel as a commercial design for resupply, refuel, repair and reloading the frigates. Now, these frigates can even deploy outside their assigned systems to a greater extent.

The utility of such ships should never be underestimated.

I'm currently considering box-launcher heavy ships and was wondering if you actually tested this concept in combat? Or anything similar?

My main concern is whether or not it requires more fiddling with targeting than with the usual reloadable launcher designs. As pointed out above, AMMs are obviously need to be dealt with manually, but what about ASMs?

Notes?

ASM does not require any extra handling at all, they just launch multiple missile per launcher and that is it.
