Speys were available from approximate 1964 onwards. Conways were available before that in the late 1950s. Both were turbofan engines.
Basically you'd have at this point in time from the UK, the following engines. All could fit into the wings of the Canberra (with a little bit of a shoehorn):

The RB.168 Spey 202 OAL includes the afterburner, which obviously isn't going to be used in
a Canberra installation. The 250/251, as used in Nimrod, OAL is 117".

Thank you
Rickshaw and
jcf, in truth the Spey plays into my
Alternative ADF ORBAT, as you see, when I finally posted the bloody thing 😩
So does the forum think that the Spey 250/251 would fit into the existing Canberra Mk20's engine cowling (what with the difference in diameter between the existing Avon and proposed Spey? I think it goes without saying that an engine change would be a major part of this
Canberra SLEP project, but so would it's cost contribution, if it nesesitated a major engineering rework or the existing engine mount......
Thanks again for your contribution and input!!
As a side note, does anyone know the specific Rolls-Royce Spey model (designation) that was proposed by Douglas to be fitted to its proposed Spey CA-4E Skyhawk design???
I'm sure in an article I read that it said it was the same non-afterburning variant as used on the Nimrod.....If so, this would be awesome in relation to my
Alternative ADF ORBAT😯
