In the 1960s, the RAF started to examine options for land-based AEW aircraft. NASR.6166 was a joint RAF/RN requirement issued in 1962, for a carrier-borne AEW aircraft that would also be used from land bases. This requirement specified an FMICW radar.That didn't stop companies from offering alternatives. One of those was Bristol, which offered a Britannia equipped with a Marconi S-band radar. This had a 24ft x 7ft (7.3m x 1.2m) elliptical antenna in a mushroom-type radome. Transmitter power was 3 MW. This was proposed for use on overseas bases.Bristol called this the Britannia Early Warning Airborne Radar Equipment or BEWARE (apparently thought up by one of the designer's sons).(data from Chris Gibson, The Air Staff and AEW).
