This scenario is to work on how to proceed with the Scimitar FAW, Type 556 to NR/A.38 of which one example was ordered in 23 Sept 1954 XH451, canceled in April 1955.
This machine is notable for the following.
29" AI.18B, coupled with dual computer for Firestreak and Red Dean.
twin 30mm ADEN cannon.
Reheated RA.24R Avons.
Wing Area 478sqft
MTOW (carrier?) Long range fighter (two drop tanks, two guns, two Firestreak) 41,852lb.
Climb sea level 43,600ft/min
Speed sea level 690mph
Service ceiling 52,150ft
Obviously this would mean killing off the DH110 - Sea Vixen.
But to draw in required funds and capacity to make sense of this properly I suspect later marks of RAF Javelin would have to be sacrificed, at least the 80 FAW 7 that went straight to storage in 1956 because of being superseeded by FAW.8.
Possibly the mk6 needs to be sacrificed from 1957.
And certainly the 'Thin Wing' development.
Experimentation on a possible mixed powerplant variant, using a rocket motor in the tail would be explored and ultimately abandoned.
To further fund developments and make this a compromise between both RAF and RN, it seems logical the RN would have to give up on NA.39, funding instead a Strike derivative of the Type 556, such as the Type 564, albeit with reheat to make the machine more able to get off a Carrier's deck (though likely at the sacrifice of full fuel and a need to tank before the mission).
We can assume all marks come with a fully blown wing.
We can fairly easily conceive of the mkII comprising RB.106, AI.18C and Red Hebe.
As surely as we can envision an alternative using Spey's and AI.23. The latter element potentially permitting a further development as a true multirole machine.
FAA FAW mkI = 119.
RAF FAW mkI = 33+80-ish so approximately 113.
FAA S mkI = 76 to 100 (Scimitar F1 number and original order number)
RAF S mkI = 70 to 100 (F4 number and a notional figure for MRI).
FAA mkII = (circa 1965-67) 14 from the mkI run end, 15 newbuild, 67 conversions.
FAA S mkII = 84 (Buccaneer number).
RAF S mkII = 150 (P1154 and Jaguar scale number)
Having both funded varients of the Scimitar FAW, a 'common' aircraft program is agreed circa 1958-1960 and so something approximate to the two seater Type 576 is set on as the solution, comprising reheated Avon RB.146's, AI.23 and nuclear strike facilities.
Scimitar F(G)R mk II.
RAF = 70 initial, with a further 80 post TSR.2 cancelation, potential further order of a mkIII.
FAA = 140 in total.
Assuming either of these scenario's go forward, several things result.
1. Red Dean is taken to service and likely either improved marks of this or a successor SARH AAM.
2. Sea Vixen, Buccaneer, and later Jaguar are the major casualties. With the addition of later marks of Javelin.
3. common successor program is put back to the later 1970s, though initially this would be the early 1970s. This obviates any rush to OR.346, removes the F4 from both RN and RAF needs.
Beyond this therefore the question is over exports.
Sea Vixen, Javelin, and bar a few to South Africa the Buccaneer did not achieve export success.
But can we say the same of these Scimitars?
I would presume a possible rival bid to the Saudis to EE's Lightning.
