Need best 1MW resistojet

So my new design uses your reactor and resistojet designs...

I actually had to do some... modifications... to account for the fact the reactor is so much lighter (and a single unit, as opposed to the trio I was using previously) to get respectable damage out of it.

So, strictly speaking, it is no longer a KKV, though most of the damage does come from direct kinetic impacts rather than the payload.

A payload of one nuclear hand grenade and 10 10x1cm osmium rods.  At 100km relative stop, the thing's still burning when it hits the target, though almost empty.  That's about the perfect engagement range.  The first few usually hit hull, punching nice big ragged entry holes thanks to the size of the missile and its radiators.  subsequent flights tend to go through the same hole doing nothing, or get some glitchy damage results.  So, a 500ish ton explosive and some osmium fragments will detonate inside the hull and do Bad Things to the internals.

Granted, micronukes like that sometimes get... odd... results.  I took a carrier with four launchers for these things up against a pair of laser frigates, the first died after the #3 salvo...  the other survived with a railgun intact until weapons range, and even my tactical missile ships are armored solely against lasers, trusting in their missiles for standoff damage capability and point defense.
