'Light CapShip Missile' kinda reminds me of 'Fighter-mounted Battleship Turret' for some reason - the term doesn't quite fit; personally, I'd suggest another name for it, like 'superheavy torpedo' or something less like an oxymoron.
Personally, I think it's a bit skinny and apparently underarmed and underarmored to be a bomber - even with the particle cannon turrets, especially for a WC3/4 era craft - this is closer to the original Broadsword in terms of armament than it is the equivalent WC3/4 era Longbow, which has twice the missiles and guns of this thing (two neutron, two plasma) but the same torpedo capability. And there are only TWO of those super-duper torps/missiles as well, which means an equivalent capability in killing ships, assuming you need only one missile per target instead of two... but you've lost the missiles and the guns to cut your way through the escorts, and the plasma guns of WC3 could let you start chewing through light capship armor as well.
