Open the nose cover and this is what you will find - a massive radar scanner measuring about 8 ft. wide by 6 ft. high. Use of nose and tail radars on the AEW Nimrod is considered by Marconi-Elliott to be preferable to the over-fuselage system on AWACS as there is no shielding from the aircraft's wings and fuselage
The AEW Nimrod development aircraft, a converted Comet 4, XW626 from A. & A.E.E. Boscombe Down, shortly after roll-out at Woodford on 1st March 1977. So far it has only the nose radar, developed by Marconi-Elliott, but the tail system is identical. Flight tests are expected to begin in June.
