My heavy flak/EFP missile utilises The following setup : A 2 kg octogen charge with an 8kg Osmium EFP on top of it.. ~30cm diameter. Followed by an 30kg shrapnell charge (round pill shapped ) that uses a smallish amount of exlosives to break up into ~2/3 kg chunks. Then : 10kg shrapnell charge that breaks up into ~5g bits. Again round pill shaped. And lastly : The stock 10kg flak explosive rod ( 5000 2 g bits ). I think I settled on a 100m standoff range on the explosives. IIRC it uses a 28kN LOx/Decane thruster. Has around 7g Accell and just under 3km/s dV. Its a bit of a chainsaw vs stock designs..... It produces 3 distinct cones of shrapnell (4 if you count the EFP ). 1 tight dispersal with the heavy chunks. 1 low/medium dispersal with the 5g bits. 1 wide pattern with the side blast 2g flak storm. Its quite versatile vs both enemy ordnance and capital ships. I might have missed something, but we can now do duel-charges in warheads now? Why not ? As long as the fuses are set on the same distance I havent seen any problems. My heavy flakEFP produces large pie plate holes surrounded by tons of flak impacts.

Next up are my 50kg class missiles.
Smallish 4to5kN thruster. Again LOx/decane.
I have 2 warhead combos ATM for EFPs. One uses the standard 2/8 Octogen/Osmium EFP combo in the nose. 250m standoff.
The Other EFP uses one in nose and one behind the smaller decane tank which is above the larger LOx tank.
I seem to be getting more ragged holes and more complete penetrations with the double EFP charge so it seems worthwhile for the small dV and g costs of the slightly heavier missiles.
For more Science I may follow up with a small 20cm or so spacer and a 3rd EFP with a slightly smaller Octogen charge( 1.5 kg or so ).
My KKV is fairly standard : small armored internal nose cone 5mm thick under silica Areogel. Payload is a 3 x 45 cm Osmium rod.

I have been meaning to experiment with small (<1kN) no gimbal control thrusters near the nose of my heavy flak missile. The missile weighs about 400 kg. And 4 thrusters are about 8kg. For some reason they really cut into dV though. I think I will try using a different fuel for em.
I guess it is because the usual 3 degree gimballed missile engines ostensibly also generate dV by the wide turns they are required to make. Overall that procedure seems more wasteful to me however.
I wonder if missile survivability will go down with more off angle missile main thruster burns.

Haven't noticed the resistojets . I'm still deep in making the smallest useful missile. Remote control now seems awfully large however Talk's cheap...we want the pudding.

Try strong metals instead of ceramics as radiators ?

For those who need to do their killing on more of a budget, but still want unreasonable levels of penetration, I can offer a line of 15x400cm conventional missiles. No treaty violations with these! The first is a pure kinetic kill vehicle, with a 10kg osmium long-rod penetrator. It's most deadly at long range, and has demonstrated a penetration of 50cm of RCC when near its top velocity, and repeated strikes to the same area can breach a full meter of RCC. Cost is under 350c per missile, and mass per missile is just over 57 kg. And for the safety-minded among you, it's a nonexplosive bi-propellant design. For those who are willing to sacrifice long-range penetration performance for good performance at any range, we have a conventional explosively formed penetrator variant. The CEFP uses an 8kg copper slug propelled by 2kg of octogen to offer 50cm of penetration vs RCC at ranges as low as 5 kilometers, and in testing has also shown the ability to penetrate 25cm of vanadium-chromium steel in a single hit. The flexibility of this variant comes at a slightly higher mass, but a significantly lower price tag. Each missile weighs in at 58kg, and costs less than 300c. With the power to penetrate the armor of even the largest USTA and RFC capital ships at 1/5 the price of a standard USTA/RFC flak missile, defending your moon, dwarf planet, or asteroid's citizens from the threat of takeover by "wealthy" navies has never been easier. Think of your citizens. Think Salacian Naval Surplus. This message brought to you by Salacian Naval Surplus Liquidators, Inc.Could you post your engine designs and the detonation range on the explosive?

Ive been experimenting with adding a 1kg rad shield pill a ways behind the main penetration rod. Usually between the fuel tanks. Cant hurt to have a second penetrator behind the first. And it spreads the damage if the missile is wobbling.

The armor I use for my 4 to 5 kt missile schooners is as follows : Inner to outer.
2.5cm RCC 2 cm VC steel 2 cm Boron Carbide 1m empty space 5mm Aluminium 2cm Si-areogel.
I may switch the Al to Boron and increase the gel to 3 or 4 cm.
It gets a fair amount of bounces vs the AI drones.
Nukes tend to heat the outerlayer.
I'd pay to be able to get another layer or 2 in the armor matrix......

Theyve invested alot more in astronauts, so they also invest alot more in astronaut food
