>Nine years after contract award, the Sentinel R1, fitted with the ASTOR radar, officially entered service with the Royal Air Force on Dec. 1. (UK MoD photo)The MoD has today declared the technologically advanced ASTOR (Airborne Stand-Off Radar) in service with the RAF, on the Sentinel R1 aircraft.>> The new radar system will be operated by the RAF's Number 5 (Army Co-Operation) Squadron based at RAF Waddington in Lincolnshire providing a new all-weather intelligence, surveillance, target acquisition and reconnaissance capability to assist commanders on the battlefield.>> Operating at altitudes in excess of 40,000ft, for over 9 hours at a time, the aircraft is capable of detecting and recognising moving, static and fixed targets at stand-off range. This information is transmitted in near-real time to commanders on the ground, enabling rapid tactical planning and efficient cueing of other sensor and attack systems such as Reaper and GMLRS (Guided Multiple Launch Rocket System).>> Minister for Defence Equipment and Support, Quentin Davies said:>> "The new ASTOR system onboard our Sentinel R1 aircraft is a unique and technologically advanced capability that will deliver exceptional battlefield surveillance. The ASTOR radar will link up with other intelligence-gathering equipment providing commanders with a complete picture of the ground allowing them to make immediate decisions on operations.>> "ASTOR is already providing a number of UK companies the opportunity to participate in a high-technology programme ensuring that the UK remains at the forefront of defence technology. I am delighted to welcome this vital asset into service with the RAF and Army.
