Brimstone is a further development of the Hellfire anti-tank missile carried by the AH-64 Apache attack helicopter. Effectively the same missile body but new electronics and seekers inside and designed to be fired from faster moving aircraft (fixed wing jets).
Sadly, the Tornados are all retired from RAF service and they're disappearing from the Luftwaffe and the Italian Air Force as well. But Brimstone is compatible with most NATO fighter and attack aircraft.
