In Action
31 Squadron - RAF Marham
Following live firing trials with Brimstone equipped GR.4s of 41(R) and 31 Squadron at the China Lake range in 2005, 31 Squadron was declared fully operational with the missile to become the lead unit with the weapon. 
Brimstone has been developed utilising both high altitude dive and low-level attack profiles. It is a fire-and-forget missile for use against armoured targets on the ground. Target designation can be made using the Head Up Display (HUD) and through the Thermal Imaging Airborne Laser Designator (TIALD) pod. The missile when fired from as far as six miles (10km) from the target drops to a cruise height and using its own terrain avoidance radar proceeds to the target.
