Hawker Siddeley P.1154

[Pirate Pete]

What where the expected performance parameters for any of 1154 variants? Like maximum speed (more precisely than simply M2), ceiling, g-limits, endurance? Ability to use combat vectoring like the Harrier?

I fear you may be asking for too much here...TSR.2 had designed performance targets, but I am not sure if any were met in reality (In know for sure that range fell short against field take-off performance...
As far as 'Combat vectoring', IF I recall correctly V.I.F.F.ing (vectoring in forwards flight) was never part of the intended operational characteristics for the Harrier and I think (and I stand to be corrected) that it was the United State Marine Corps Aviators who were the first to do it and introduce it...It was then used by the R.A.F....So, it would not figure in The P.1154's intended operational planning at the stage the design was at...

In a slim hope there are any known details about aerodynamic testing or even just theoretical calculations.

Put another way, it may be asked which contemporary existing fighter it could have been closest in performance to as some kind of benchmark?

The first picture
I think that this picture shows Royal Navy version, because perhaps there was no double seat version plan for the RAF.

The second picture
A cutaway of the P1154 as submitted for NBMR-3. Of note is the Bristol Siddeley BS100/9 turbofan, fitted with plenum chamber burning in the front nozzles. The store on the centreline pylon is a ‘shape’ representing a tactical nuclear weapon.

Probably a B28EX.
