What about the Fairey Rotodyne, this was cancelled in 1962. Is it allowed in this GB?

Certainly, it might have been useful in Vietnam.

Quote from: zenrat on January 23, 2024, 03:53:39 AMSo what you are saying is that while use of the vehicle may have begun in the fifties or earlier and/or continued into the seventies and beyond, to be valid for entry into this GB it must be finished in a specification and scheme it bore between 31/12/1959 and 01/01/1970?

affirmative / yes

I'm considering a Star Trek build.   Of course, the subject would be based in the future.  But it'd be firmly be based on the TV show (TOS, not the later films or shows), I'm guessing this would be okay?

After a bit of thought we think this is ok as the original series was in the 60s

It would be a common problem for every science fiction/fantasy book/movie/series. I think reasonable to consider (as you did) the years of the original issue.

Now I'm wondering it it was possible to get the MBT-70 into service before 1970. Not sure if enough Handwavium exists in this universe.

You should at least change the name to MBT-69 . 

Another Lockheed Constellation C-121 to my list of builds.

Sure you could because if one wants to be accurate the 1960s - the seventh decade of the 20th century - started 01 January 1961 and ended 31 December 1970. There's never been a year Zero.

How about a slightly lower-tech MBT-70 with fewer radical features. Some in the US armour community wanted a collaboration with the British rather than the Germans: what if that had happened, and "MBT-69" had been essentially like a Chieftain with a more powerful engine, hydro-gas suspension, and the XM150 gunn/missile launcher?*

*And yes, I know the 152mm gun/missile launcher was awful, but the US was committed to it in the '60s and we're trying to get this into service by 1969, not make it perfect. You might imagine a situation with the British similar to that with the Germans on MBT-70, where they reject the 152mm and insist on their version having the 120mm L11 instead.

development work was in the 60s and the prototype was running in 60s

It has been argued (not by me) that the sixties didn't really get going until 1964 with the Beatles and didn't finish until '73 with the oil crisis.

I can see that argument having been 12 in 1964. They were certainly two distinctly different half-decades
