The Lambda was reasonably well-armed, with three double blaster cannons (one rear-mounted) and two double laser cannons.[16] The military version built by Cygnus Spaceworks was armed with ten laser cannons. It was also protected and a powerful deflector shield, which was powered by a pair of generators. source:http://starwars.wikia.com/wiki/Lambda-class_T-4a_shuttle
