Wonderful plans of these post war potential crafts.. It strikes me that the your first Hawker P1067 images and the last Vickers type 553 look like later Soviet production models? Which I guess, having growing up in the UK through those Cold War 60's 70's decades is of no surprise.
I had a most favoured Uncle, who used to tell us, as young children on holidays, the most oddest tales of these invented naughty characters he names Red, Bluey and Whitey. and what mischieve they would do to each other. Sorry to digress so much. but this Uncle worked as an "M" for the British Foreign Office / Ministry at GCHQ in Cheltenham. Its only now ( when I cannot ever remember his story details ) that he probably invented these characters as a way to unwind from the reality of what he was working with or all the US,GB CCCP juggling he was involved with. He would always later say to me "the things that I know, would make your hair stand on end" of course he never would reveal anything further - and would often add - "they only let me know half of it all, in case I'm captured by the Soviets.. Oddly enough well after his retirement he was offered a free expenses paid trip to visit the USSR anytime, in the early 80's (prior Berlin the wall coming down).
Really sorry to ramble so here, but there is always some back story to our fascination with all this secret project effort
