Ships started warping in to help
x100 Armed Cargo Ships/Fighter carriers
x200 Heavy Fighters
x3000 Z-11 Swarm Fighters
x50 MKII Battleships, 

The Cargo Carriers had strong sheilding and tons of flak, while the battleships had plasma cannons, The Heavy fighters built to rip fighters to shreds, and the swarm fighters as cannon fodder
(PS: The battleships also have Ion lasers and the little emp guns)
