This design is for a pdc capable of housing 1 battalion of marines divided into 5 companies and 5 assault shuttles to transport them, although it doesn't really exist it's purpose would be to deal with smugglers and pirates on intersystem trading routes, this design is at the maximum for a 2 section prefabrication since the barracks and hanger alone take up more than a single section, doesn't really have any defenses either but it's cheap

This is an even smaller Complex, it's just a single quad barreled laser turret enough power to fire it and aiming systems, the rest of the 2500 tons is armor just to make it more annoying. Since it's a single section prefab it's very easy to make and drop on an asteroid. The plan would be to seed an inner system asteroid belt with these to delay and aggravate an enemy fleet, also because it's very heavily armored for it's size it's hard to kill. It would also work in conjunction with the 1 section missile complex I am developing, acting as an anti-missile laser defense, there will also likely be an anti-missile gauss cannon battery to go with the set for additional missile defense.

You could probably save some space by reducing the size of  the fire control as it has far too much range and tracking speed compared to the weapon it is controlling. Also, I do not think Plasma Carronades work in an atmosphere, might be best with a Meson based weapon.

I know this isn't really a good comparison, but the following is my Full Blown Colony PDC:

The Long Range Search Sensor covers the approaches and acts as an early warning.

The Anti Ship Serch Sensor is tied into the Anti Ship Fire Controls to take on the destroyers and up.

I can switch over to the the Anti Gunboat Search Sensor which is tied into the single Anti Gunboat Fire Control incase my ASFC can not lock onto a smaller combatant.

I have a ridiculous throw weight in terms of Anti Missiles and because this is based on a Colony that will have production/stockpiles I do not need to worry about reloads if the engagement takes a long time. (although I think Steve may have implemented a delay in reload from Colony stockpiles now?)

The thing with this is that all an enemy has to do is skirt your bases by 100k km and they will be fine. Later, they can stand off at a million km and throw a couple of salvos at you, the best you can do is take out 4 missiles every 5 seconds. I would suggest some way of projecting fire power, if you are producing dropships then I guess you could maybe produce a beam armed fighter?

[AtomikKrab (OP)]

Well for one these pdcs are intended to be placed on asteroids thus negating the atmosphere problem

as for the other things, it's only a 2500 ton installation, it's not meant to survive only to delay.

and really each of the 2500 installations will work together, so I will be making a combined installation of 10000 tons later, but these are made for portability onto asteroids.

So while for the laser or gauss installations it's possible to sit outside the range and shoot missiles, when the anti-missile missile complex and anti-ship complex are added it becomes a layered threat.

So really if you want think of these as individual components of a 10,000 ton installation

Your active sensors are very myopic. A properly routed course could thread a path through the defense belt without the bases being able to engage. You might consider large passives, both EM and Thermal.

Hopefully you noticed the 'efficiencies of scale' in Aurora (that 'filler' you had to add to get up to 10,000 tons).  Armour, crew quarters, magazines & sensors will be your PDC's biggest savings, but don't overlook that 'final defensive fire' point defense is more efficient when protecting the unit than its nearby allies.

In other words, one big PDC is more efficient than several smaller ones.  The same for ships, assuming they're always going to work in concert, and not split up.  PDCs are easy, since they don't move.

[AtomikKrab (OP)]

yes, but an anti-missile pdc is worthless against a nonmissile using NPR

[Brian Neumann]

yes, but an anti-missile pdc is worthless against a nonmissile using NPR

This is actually not quite true.  You can load the pdc with some small missiles that will be fired from those launchers to shoot at enemy ships instead.  The only weapon that will not work against an enemy ship would be a CIWS system.  Everything else can at least theoretically shoot back at them.  Admittedly the gauss cannon are useless in any type of atmosphere and have a very short range, but they can shoot at a ship that is in range if they are on an airless rock.

[Father Tim]

Straight size 1 missiles launchers are about 50% as efficient as the same total tonnage of mixed PD and AS launchers (say, size 1 and 6) - you give up range & penetration vs size 6 (or 8, or whatever) launchers, but make up for it in numbers and reload rate.  You can build two sets of size 1 missiles (PD and AS) or design a slightly more dual purpose standard missile.

You sandpaper your opponent's armour rather than blowing holes, but you still destroy him in the end.

[Andrew]

I am seriously considering a design philosophy of only using short range size 1 missiles for antimissile work and antishipping work , because it is so hard to get missiles throough a fleets defenses with comparable technology. The otehr two alternatives I have are large numbers of Box launchers for massive salvo's or relaying entirely on Beam weapons for offense.
In a couple of warp point assaults I have found that the rapid firing missile launchers , do a good job of sandpapering my enemy to death and have the advantage over missiles that if he is faster and armed with longer range beams he cannot stand off outside my range , in those cases I was just using the normal antimissile launchers I fit to my fleet , although I now tend to carry a small number of light antishipping missiles with slightly larger warheads and less agility and speed

[Rathos]

I've been using MIRV weapons to great success.

You can design several types of missiles of different size, then put them in a mirv pod.

Depending on the type of MIRVs it carries it can have its own sensors or not.

Now, strapping a MIRV pod in there reduces the overall space you have for making your missile so it is slightly less efficient, but this is made up for it's customizability.

I use the large 100 size missile now, and it has several MIRV configurations.

First is a anti-super-heavy-torpedo design that is meant to take out those pesky heavily armored torpedoes. I don't run into them myself much (Actually the only ones I've seen are the ones I carry)

Second is a anti-fleet MIRV that carries 10 size 10 missiles that each have their own small sensor. The extra range from the pod helps boost the distance I can hurl them.

Third is my "sandpaper punch" pod that carries 95 size 1 missiles. The idea here is to use a slow moving pod, and to time your normal launchers to have their missiles fly by the pod as soon as it releases its payload to create a really huge sudden strike of missiles to confuse their PD into shooting the smaller sandpapers while ignoring the giant torpedoes.

I plan on using size 1000 box launchers to make even larger versions of the above as soon as I research them. (Even 10k size box launchers on my battleship+s  :wink: and still do a lot of damage and go fast)

[waresky]

Rathos..u "cheat" tech tree?or u reach good tech level in "real" research mode on?

[Rathos]

In 4.9 everyone starts off with size 100 launchers  :twisted:

I did put research costs on the new launchers though, so I have to work my way up to them. (1 million RP points for a size 10000)

The largest launcher I have access to in my current game is 150, though in 4.82 I had 500s and 1000s. I also tested out the size 10000 and 100000 launchers in a "Cheat game" to see if they broke anything.

I don't really cheat my tech, other than instanting a racial when the one I designed before I accidentally "messed" up. I do like to start off with 200k tech points and 40 labs right off though.
