Recepy for no sweat group NPC capitals killing (for missions at least):
Any Battleship who has 2 heavy slots on same side of ship , so you can mount 2 Nightamares, turn that side of ship toward group of NPC capitals (so that nightmares fly straight to them from moment you launch them, not at arc) fire both nightmares in 2 secunds interval toward ship that is in middle of group and then collect loot.
Valor for example have 2 heavy uo and 2 heavy down, equip 2 nighmares on top, charge toward group of enemies, lock missles on one in middle , engine kill, turn your top side down so Valor top side face oponents, fire nightmares with little interval betwen then and wait sound of masive explosions.
Since Nigmares have huge explosion area, First nigthtmare will deshield hole group, second will finish them before their shield regenerate , only few high HP Battleships can survive this tactic, for them you need third nightmare launcher on same side (Sarrissa for example have 3 heavy on top if i am not mistaking).
