Philip Zarraga is worried that failure to bring into service a replacement patrol aircraft has left the UK and Europe "deficient"
Mr Zarraga, aged 72, from Loughborough, became chief pilot for JCB in Staffordshire after he retired from the services.
He flew 2,000 hours in Nimrods from 1976 to 1980.
The aircraft have been withdrawn but today an old one was on display to aircraft enthusiasts at Bruntingthorpe airfield in Leicestershire.
Two men who refuelled the Vulcan which disabled the runway at Port Stanley in the Falklands War with Argentina were back in the type of Victor aircraft they used.
Mike Beer, an air electrician officer in the Victor, says he too is concerned about the state of Britain's defences.
The Ministry of Defence says our ability to operate maritime patrol aircraft is being maintained.
