I went ahead and designed this frigate based off my usual frigate design.  The fallout of the engine changes is pretty massive, I think I will need to put tankers with my ships now. 

Just a reflection...

I learned the hard way that you do not want your engines to be too big on a smaller ships. The problem is when the engine is damaged due to combat. It take you twice its cost in supply to repair and often they can't do that. So they will have to be tractored to safety. Often that is not an option.

Unless you don't care for damaged ships that is... ;)

To your point about different approaches...

In the equivalent role of the " Iron Fist" TG I'd be using 6 25k ships.  Using the research points I extrapolate from the test battle post my tech choices would have  been very different.  The result is a class that has armor 6, delta shieldsx36 (90), single 30cm C3 Plasma Carronade, 1 BFC 4xRange, 1 quad GC R1 (1x12) turret, 1 BFC 4xSpeed, 10 sz1 ROF-5 std launchers, 1 res1 4hs(3m/km vs sz6 msl) MFC, 12 sz4 ROF-20 std launchers, 4 res100 2.75(190m/km vs 5k/ton) MFC's, magazine capacity for 47 salvos sz1 48/kps wh1 m24 and 22 salvos sz4 40k/kps wh6 m10, 1 res100 8hs(184m/km vs 5k/ton) AS, 1 res1 12hs(3m/km vs sz6 msl) AS, 1 sz4 EM Sensor, 1 ECM-2, 5 conpact ECCM-1, 1m liters fuel.  And 12 months crewquarters.

This is just the extrapolation using my prototyping worksheet not actual games stats.  But does follow my design protocols for 25k/ton battlecruisers.  On paper the AMM's should stop all 120 other  either torpedo version and only expend about 70% of the on-board stock.  Conversely the ASM's likely wouldn't penetrate a Liberty's armor belt.  The ASM damage potential is do to having 1 more salvo per volley than the defending TG has defensive fire controls.

Though the missile bombardment version would be a very different result.  It was developed to address the issue of heavy GC turret usage when they were introduced to Aurora.  The above stat's drop the shields, PD turret, and offensive beam in favor of adding another 9 sz4 launchers and 3 MFC's.  This configuration has a volley of 42 salvos of 3 missile each.  That's 20 salvos more than the defending TG has the ability to intercept.  It should only take about half the ASM's in the magazines to at least disable all 3 Liberty BC's.

Both of these standard TG's are vulerable to smallcraft swarms designed to using res100 1hs(69m/km vs 5k/ton) MFC's.

In essence I would like to point out (as I did in that post with the test) that both fleets were suboptimal by design and that I intentionally avoided gauss cannon spam.

It is more than doable to counter missile fire-controls with gauss pd fire-controls they are roughly equal in cost but the gauss cannon are practically free in comparison with all the missiles that you need to produce to support the missile weapon system.

In a normal fleet I usually attach frigate escorts based on my intel on the enemy and what type of ordnance I know that they use. If I'm unsure I go with one AMM frigate, one laser frigate and one gauss frigate. There might sometimes be a few more beam armed frigates for every AMM. Gauss frigattes are between 4500-4800tons and have two 67% quad turrets each with a fire-control. They are specifically designed to combat fighter launched salvoes.

Even trying to compare is rather futile because any fleet composition anyone make here can be countered somehow. My balanced fleet composition can probably be beaten by any other composition but not easily by anyone in equal size at least. By providing a large compliment of beam PD I make sure that I free up my industry and naval yards for producing more ships or infrastructure instead of expensive missiles. When beams fire their ammunition is free. They are also complimented by AMM that can be used if I feel there is a need for them. It is possible to target AMM by hand. That way I can destroy entire salvoes instead of saturating every salvo with a few missiles. I just need to make sure I have a high fleet training level on my ships. ;)

You must agree that in the engagement between the Freedom and Iron Fist fleet the Freedom fleet came out on top in terms of industrial capacity in replacing their respective losses after the engagement?

Below are some comparison in cost of different systems using approximately the same technology levels.

Code: [Select]
70mm Phalanx PD System (67% miniaturized quad turret), size 20.61, Cost 119
Point-defence Fire-control, size 4, cost 77

This turret will on average shoot down about 4-5 equal technology fast missiles per turn.

Total space: 25 HS, 1250 tons
Total cost: 196 BP


Code: [Select]
3 size 4 missile launchers, size 12, cost 84
Missile Fire-control, size 3, cost 63
Magazine space for 21 salvoes missiles, size 15, cost 90
63 size 4 missiles, cost about 220

Total space: 30 HS, 1500 tons
Total cost: 457 BP

So, in general it is very hard to out perform a PD turret in terms of both combat and industrial efficiency when you use full size launchers. In my opinion this is a good thing because it is generally easier to attack then defend so defence should in general be slightly cheaper in comparison.

The above turret is the most common point defence system on my ships in general. My laser PD frigate only has one fire control but their role is engaging larger salvoes of heavy missiles. They generally come in waves of 10-20 in each salvo so one fire control is more than enough in one battery with two quad turrets.

All in all I feel that there are no direct point in saying you can't counter full sized launchers. Its only when you go below size four you will have a chance to beat them in combat efficiency but not in industrial efficiency. Size two beat them without question. But in my games I don't use ASM with size less than four anyway.

My suggestion could be to increase the number of launchers to five per fire control and include two armoured dud or yield 1-2 missiles and three high yield missiles. That would certainly make my defence much more dicier if countered with a great number of gauss PD systems. There would be allot more leaks from every salvo.

Weasel missiles help with AMM saturations as well. Lets say that your first three salvoes have three weasels and two regular missiles. The next three has three regular and two weasels while the next three are only regular. You then start with weasels again of you have to to make sure your regular missile hits home. Weasel missiles are also incredibly cheap to produce.

Something like this could work perhaps...

Code: [Select]
Missile Size: 4 MSP  (0.2 HS)     Warhead: 6    Armour: 0     Manoeuvre Rating: 10
Speed: 40000 km/s    Engine Endurance: 61 minutes   Range: 146.0m km
Cost Per Missile: 3.5
Chance to Hit: 1k km/s 400%   3k km/s 130%   5k km/s 80%   10k km/s 40%
Materials Required:    1.5x Tritanium   2x Gallicite   Fuel x1250

Code: [Select]
Missile Size: 4 MSP  (0.2 HS)     Warhead: 0    Armour: 1     Manoeuvre Rating: 10
Speed: 40000 km/s    Engine Endurance: 61 minutes   Range: 146.0m km
Cost Per Missile: 2.25
Chance to Hit: 1k km/s 400%   3k km/s 130%   5k km/s 80%   10k km/s 40%
Materials Required:    0.25x Tritanium   2x Gallicite   Fuel x1250

When this method is used relying on AMM alone will be a very expensive proposition indeed. You will probably be force to start using a serious part of your PD duty to beam weapons.


And... lets not argue this as if it was a competition... (my fleet is bigger and tougher than yours) neither will win.  ;)

Here is another interesting approach I have been contemplating. It actually is reasonably cheap and I could produce this ship in my military auxiliary ship yards.

Materials Required:    3.25x Tritanium   3.504x Gallicite   Fuel x2025

The missiles are not really optimised and could perhaps be reduced in range a bit but I just took the designs I had.

This would obviously be a highly specialised missile strike cruiser and be operated in independent squadrons of three to five ships attached to battle-groups in need of extra heavy artillery fire-power.

The ship is pretty cheap at about 3500 BP and its ordnance has total cost of about 800 BP

can other players see two different types of missiles coming at them? or can they not determine which ones are armored and which ones have warheads?

They can tell the difference, but you don't get a choice of which to shoot.  You shoot all of them or none of them (or you manually target, which is 5s slower per salvo and subject to fire delay)

I have a question about armored missiles. Do they work let's say with 0.5 armouring or the armor has to be exactly 1 or more?
If it's stupid but it works, it isn't stupid.

Acording to Steve they should work with fractions from an old post I found. But my investigations by testing seem to show that fractions below one does not work. Testing fractions above one is harder. I have reported it as a bug a while ago.

I stick with whole numbers for now.

Thanks.
By the way after my experience with the swarm i decided to design a special missile for countering their high speed FACs. It is on ion tech and has a reduced range in the favor of speed and agility and IR sesnsors.

AS-52 Sidearm
Missile Size: 5 MSP  (0.25 HS)     Warhead: 4    Armour: 0     Manoeuvre Rating: 17
Speed: 25200 km/s    Engine Endurance: 13 minutes   Range: 20.0m km
Thermal Sensor Strength: 0.0296    Detect Sig Strength 1000:  29,600 km
Cost Per Missile: 3.3036
Chance to Hit: 1k km/s 428.4%   3k km/s 136%   5k km/s 85.7%   10k km/s 42.8%
Materials Required:    1x Tritanium   0.0174x Boronide   0.0296x Uridium   2.2566x Gallicite   Fuel x475

Development Cost for Project: 330RP

I am not sure about the thermal sensors. Is their range ok for targeting FACs?

Yes, and that is normally why you don't want to run with zero yield armoured missiles or those with very low yield. They can be safely ignored but it means more micromanagement to do so and you might loose some small efficiency since whenever you give them a new target you loose 5 seconds.

It should also not be used to saturate enemy PD with firing more salvoes. Because in essence you get two salvoes from each fire control for PD to engage and PD will engage every missile.

If you are playing against another player I would just make up some ground rules for how you want to play it. The easiest is probably that no manual targeting of AMM is allowed and that salvoes with mixed missiles has to be big enough so you don't saturate enemy beam PD fire-controls that way, or just a rule that you can't mix missiles in the same FC.

Well, those little buggers have a 160 thermal signature and a 10000 km/s speed...
Your thermal sensors seems quite weak for this purpose
(I think that you need to be able to detect the ennemy after a 5 second movement phase - so you'll need a 50000 km detection range for a thermal signature of 160 / more than 300000 km for a thermal signature of 1000 if the formula is linear)
