The stuff the SARF SMEs had to trawl through had a little to do with the radar but plenty more to do with claimed performance of both the aircraft and equipment not meeting claimed specification by the bidders.
I had no intention of reopening the radar debate though some here seem very sensitive about it.
I am also very aware that the civsar capability as presently demonstrated by CHC up North is (apart from lack of NVG) very impressive and the layout of the back of the aircraft (and the cockpit I suppose) puts the Sea king to shame - as it should since our aircraft is 60 plus years old.
However it is not the RAF's fault that the AW139 is not fit for purpose as a SAR aircraft.
