"The ""Nimrod"" reconnaissance aircraft is based on which former passenger aircraft?"
Hawker Siddeley Nimrod R1 Hawker Siddeley Nimrod R1 The Hawker Siddeley Nimrod R1 is a signals intelligence aircraft formerly operated by the Royal Air Force. The aircraft was a conversion of the existing Nimrod maritime patrol aircraft, with all of the electronic equipment and armament optimised for anti-submarine and anti-ship warfare, and search and rescue, replaced by equipment for the gathering of communications intelligence and electronic intelligence. In 1958, 192 Squadron took delivery of a pair of Comet R2 aircraft, converted for use in the signals intelligence (SIGINT) gathering role, to replace the Avro Lincoln and Boeing Washington aircraft being used in the role.
Reconnaissance aircraft Reconnaissance aircraft A reconnaissance aircraft is a military aircraft designed or adapted to perform aerial reconnaissance. Their roles include collection of imagery intelligence (such as photography), signals intelligence, and measurement and signature intelligence. In addition to general intelligence gathering, modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance. In years prior to the development and common use of sophisticated electronic sensors (such as radar) and image recording devices, reconnaissance aircraft were also relied upon by military forces for distant visual observation and scouting of enemy movement. An example is the PBY Catalina maritime patrol flying
