A salient-characteristic resized Stinger. Same KE output, ammo, range, fuel, armor, with better DV/accel. Just to show how bloated some designs end up. Lighter and cheaper with the exact same performance.
Add in a 947kg Flourine tank and 100kg Methane tank. This takes 16 of the beer can size reactors from the reactor thread.

A tongue-in-cheek replacement to meet the challenge specs. 60 conventional guns, 10 coilguns, micro missiles, and gold plating standard over diamond armor. For when you have to kill the enemy in style and spare no expense.

Argh, now I REALLY want to test these.

So I detuned my very rude railgun below 100% efficiency. This resulted in a shorter barrel and very large mass savings.
The puzzle is now how to make the drone weigh 9.5 tons. I'll probably slap some external tanks because why not? More dv the easy way.

Make up the 'missing' mass with the tears of engineers forced to design a bloated drone the same weight as an Apollo command module.

We can make it a tenth the weight and a fourth the cost, why are you making us do this?"

Obviously, you shove in the extra mass with more guns and armor.
BECAUSE YOU CAN NEVER HAVE ENOUGH GUN AND ARMOR WHEN THERE'S FREE SPACE.

We can make it a tenth the weight and a fourth the cost, why are you making us do this?" I guess fleet command wanted to reuse the same launchers and drone bays for the stinger armed capships. The challenge was actually quite generous to not restrict physical dimensions to some percent tolerance of the original.

Retrofitting the fleet carriers to use the new drones is going to be complex enough even if they stick to the old launchers and drone bays, can't imagine how much more complex it'd be if they also needed to tear those out too and replace them.

Just put a handful of mine together with struts and put it in a big cardboard bin. Stuff the innards with the contract paperwork and presto. In reality, the stock launchers are basically short linear actuators, shouldn't be a problem to stick in an adapter for a smaller payload. Similar thought on the (likely) rotary payload bay. Think of it as a subcaliber munition. Heck, I'd offer a field converson kit and still be miles ahead of a 300kc drone replacement cost. I should add that the gold plated Stanker does have an onboard nuke warhead. Now you can bedazzle enemy ships with fragments of diamond and gold armor and increase their visual signature.

I obviously don't have experience in that particular field, but I still imagine that there'd be some non-trivial engineering going on to get the and drone sabot to fit in snugly , as well as the issue of getting the sabot to separate neatly without damaging the radiators. It'd be worse if the drone was actually longer than the Stinger, like mine is.

When the sabot leaves, the fins spring out. I believe it would be rather trivial. Also in atmosphere, any sub-caliber munition that needs a sabot discards it to reduce drag, since low cross section is the reason for sub-caliber anyway. For CDE we could have reason to believe a munition might keep its sabot after launch, since vacuum offers no drag.
