The anti-armour Brimstone missile is a UK development from the Hellfire used by attack helicopters. Although late and, as usual, overbudget it is now being deployed with RAF GR4 units. 31 Sqn at Marham are the lead squadron and this sortie in April, 2006 was one of the first operational flights by a service jet. 12 Missiles are carried on four, triple point stations under the fuselage. It's also carrying 4 ALARM anti-radar missiles on the wing shoulder stations.
