This thread has reminded me of something I came across a couple of years ago concerning Zuckerman and the TSR.2.
I came across a copy of Zuckerman's book
Six Men Out of the Ordinary, London, 1992.
In the chapter on Mountbatten he claimed Mountbatten was, "a friend of the retired naval officer who was the project manager," at Blackburn and that therefore Zuckerman avoided Mountbatten when he was asked by the Minister of Defence, Harold Watkinson, to make a review of the Operational Requirement and whether it should be relaxed.
Two weeks later by chance, at Kew I cam across a letter in Zuckerman's MoD files from that time. The letter was from Duncan Lewin at Blackburn Aircraft Ltd., dated 1st September 1960. The letter was a thank you note for Zuckerman's recent visit to Brough on 24 August. Lewin offered him the services of the Technical Staff to answer any questions and went on to say, "We are going to try to persuade the Minister to visit Brough so that we can introduce him to our ideas," and hoping Zuckerman could accompany him. Sadly the aide-memoire Lewin enclosed on the subject of their conversations was missing from the file.
Intrigued if this was the retired Naval friend of Mountbatten's I searched his obituary in The Times and his entry in Who's Who which soon confirmed the fact. Capt. (Ret.) Duncan Lewin began his career as an FAA pilot and rose to command HMS Glory during the Korean War and later HMS Eagle. He had been Director of Plans when Mountbatten was First Sea Lord. In 1971 he became Managing Director of Blackburn and in 1977 became Sales Director for Hawker Siddeley, being responsible for the Beechcraft 125 deal in the 1970s. He even has his own Wikipedia page:
https://en.wikipedia.org/wiki/Duncan_Lewin. Damian Burke's book notes Mountbatten's 'chance' meeting with Lewin at Farnborough but does not investigate the background. I find less than coincidental that Mountbatten, Zuckerman and Lewin were mutual acquaintances and there is evidence that Zuckerman and Lewin had met, most likely to discuss the Buccaneer's suitability to fulfil the OR. In
Six Men Out of the Ordinary Zuckerman claims there was no collusion though the RAF suspected it, but in reality there is no smoke without fire and we've heard many tales of Mountbatten's interference against the TSR.2.
Presumably Lewin would have had some knowledgeable input from Zuckerman on the carrier debate too.
