After a range of top fighter aircraft and other weapon systems, the US has now offered another sophisticated system to India, the Airborne Stand-Off Radar (ASTOR), whose capability has been described as "unmatched" by a former US navy official. According to Admiral Walter F Doran, president Asia for Raytheon, Indian officials had already been briefed on "this latest radar, for highly effective 24-hour surveillance and target acquisition capability", India Strategic magazine reported in its latest issue. The system is being operated now by the British Army and Royal Air Force (RAF) in Afghanistan with five ASTOR aircraft and eight ground stations. Admiral Doran is quoted in the magazine as saying that Raytheon, a military technology giant, had also submitted a formal proposal to the Indian government. He declined to give details.
