Brimstone

Brimstone

This advanced radar-guided weapon is derived from the US Army Hellfire AGM-114F missile and is deployed in RAF service on a pylon-mounted launching rack that contains three missiles.

It is powered by a rocket motor and can seek and destroy targets at long range.

Ground acquisition and target recognition are achieved by a millimetric wave radar seeker. The weapon locks onto a target after launch and is designed for the attack and destruction of armoured targets. Steerable fins guide the missile towards the target with final impact causing a tandem charge warhead to detonate. The first, smaller warhead nullifies reactive armour, allowing the follow-through charge to penetrate the main armour. It is designed to be carried by the Tornado GR4 and Typhoon F2. The weapon can be used in Indirect and Direct modes. For Indirect attack weapons are launched when the targets and their position are not visible to the attacking aircraft. In Direct mode the pilot can use an onboard sighting system to select the target, which can lie off the aircraft's track, so that pilots do not need to manoeuvre to release weapons. The weapon flies at low level, using its onboard navigation systems to head for the target and searching, using its radar, to distinguish between valid and non-valid targets. Brimstone can be programmed to start searching only in target areas, limiting risks to friendly forces.

MOD wanted a weapon that could operate in all weathers, day and night, be effective against the future predicted Explosive Reactive Armour arrays and be a genuine ‘fire-and-forget’ weapon.

After a strong competition between four rival projects, a contract was let with MBDA in 1996. Total expected cost of introducing the weapon into service is about £850 million.

The weapon went into service on the Tornado GR4 in 2005. Work continues to ensure the weapon reaches its full potential.
