"power junctions" and connecting wires, if these are destroyed, all modules and weapons will power down. Would add another level of detail in ship designs, and could possibly help balance uber-weapon ships. Causes minor damage if destroyed.
So, wires, switches, transformers, and electrical gear. Let's implement Maxwell's equations and electrical conductivity as well as insulator breakdown voltage as well as magnetic field effects in their mechanics while we're at it. Shalom differential calculus!
'Power nodes" supplies power junctions, and directly connects to aegis devices. Affected by lancet. Causes major damage and can overload/destroy connected junctions if destroyed.
And this is called a "reactor-generator set". Let's implement nuclear physics for different classes of reactor. You know what, fuck it. Let's go Whole Hog and make everything into computational engineering and design, maybe with subroutines that compute weapon effects from materials equations of state as well as thermal and fluid-mechanics modeling! Awesome!
"Anti-matter missile" Single use, very big, make-the-game-crash weapon that simply blows everything into quarks, even if intercepted. For those of you wanting to get closer to god, very quickly.
Nukegun. Stupidly-long reload into four digits, hilariously short range, comically-huge blast radius (maybe five digits), and Lucky Nines damage. DONE.
