Brimstone is an air-launched ground attack missile developed by MBDA for Britain's Royal Air Force. It was originally intended for "fire and forget" use against mass formations of enemy armour, using a millimetre wave (mmW) seeker to ensure accuracy even against moving targets.

Experience in Afghanistan led to the addition of laser guidance in the dual-mode Brimstone missile, allowing a "man in the loop" to pick out specific targets when friendly forces or civilians were in the area.
The Tandem Shaped charge warhead is much more effective against modern tanks than similar weapons such as the AGM-65G Maverick, whilst the small blast area minimises collateral damage. Three Brimstones are carried on a launcher that occupies a single weapon station, allowing a single aircraft to carry many missiles.
After a protracted development programme, single-mode or "millimetric" Brimstone entered service with RAF Tornados in 2005, and the dual-mode variant in 2008. The latter has been extensively used in Afghanistan and Libya.
An improved Brimstone 2 was expected to enter service in early 2015, but has been delayed. MBDA is working on the targeting of swarms of small boats under the name Sea Spear. The RAF are waiting for funding to fit Brimstone to their Eurofighter Typhoons and planned to integrate it with their Harriers until they were withdrawn from service in 2010.
MBDA are studying the use of Brimstone on ships, attack helicopters, UAVs and from surface launchers; it will be integrated on the F-35 Lightning II when the F-35 enters British service. The US, France and India have expressed interest in buying Brimstone for their aircraft but Saudi Arabia is the only export customer to date.
