of the engine. EFE – Environmentally Friendly Aero Engine is a 95 million pound programme, carried out by Rolls-Royce and a first engine run is planned for 2008. Its aim is to prepare the UK industry for future engine programmes and from a technical perspective, its aims are a 10% reduction in carbon dioxide emissions and a 60% reduction in NOx emissions. UAV Engines Limited (UEL), a British company owned by Elbit of Israel, is one of the largest suppliers of UAV engines in the world. Their engines, ranging from to , are installed on 25 different UAV systems. It will provide the engine for the British Army's Watchkeeper UAV. Reaction Engines SABRE, a hypersonic precooled hybrid air-breathing rocket engine currently in the early stages of research and development. It is being developed by the British-based company Reaction Engines and is expected to power their Skylon spaceplane with a planned first flight by 2025. Missiles ASRAAM, a short range air-to-air missile developed by MBDA UK. Brimstone, an air-to-ground missile developed by MBDA UK. CAMM, a family of missiles which includes versions for air, land and sea environments. It is developed by MBDA UK with technology sourced from ASRAAM. Martlet, a lightweight air-to-surface / surface-to-surface missile developed by Thales Air Defence with technology sourced from Starstreak. Meteor, a pan-European beyond visual range (BVR) air-to-air missile. The UK is the lead developer. Sea Venom, a lightweight air-to-surface / surface-to-surface anti-ship missile developed in cooperation with France. SPEAR 3, a network-enabled anti-ship, anti-tank and anti-ground mini-cruise missile developed by MBDA UK. Starstreak, a short-range surface-to-air missile, originally developed by Shorts Missile Systems, (now Thales Air Defence). Storm Shadow, a long range stand-off cruise missile developed in partnership with France and Italy. Perseus, a hypersonic anti-ship / land-attack cruise missile being developed in partnership with France. Radars Euroradar CAPTOR, the radar developed for the Eurofighter Typhoon. It has been developed and is being produced by the Euroradar consortium, a joint venture of major European radar houses. The UK contribution comes mainly from Selex ES (formerly Ferranti). The CAPTOR is based on the Blue Vixen radar of the Sea Harrier FA2. Euroradar CAPTOR-E, the AESA variant of the CAPTOR radar which will equip later tranches of the Eurofighter Typhoon. A CAPTOR-E technology demonstrator, called CAESAR, first flew in early 2006 on a BAC 1-11 and has since then also flown on a Eurofighter development aircraft.
