Ironsides IRN-SD1b

The Ironsides IRN-SD1b is a 65-ton fighter flown as a dogfighter. It replaces the IRN-SD1's pair of PPCs in the nose with ER PPCs in the same position, keeping the SRM 6 in the nose, the paired SRM 6 and Medium Laser in the right wing, and the paired SRM 6 and Medium Laser in the left wing. The fusion engine gives way to an XL engine, and heat sinks rise from 10 to 15 double heat sinks. CASE is fitted in the fuselage, and the fighter carries standard armor. Brooks Incorporated builds it at Carver V / Liberty.
