Does the BAC-111 have Medways instead of Speys? Allowing it to have a proper development programme would allow it to give the Boeing 737 and Douglas DC-9 a run for their money.Step 1 - DH.121 is not shrunk into the Trident, and give the Boeing 727 a run for its money

The extra sales are going to give Rolls Royce a healthy bank balance. That is until 1971.Snip to Post 39.
More Tridents means more cash for Hawker Siddeley and more BAC-111s means more cash for the British Aircraft Corporation.Snip to Post 39.
If Medway is chosen for the TSR.2 will it also be chosen for Concorde?If....if Government had allowed it RR Medway was the preferred engine on OR.339 submissions, rather than BS Olympus.
Assuming funding for TSR.2, Viggen will follow. Reheat addition is already funded in TSR.2 effort.
Making license for Mirage F2 F3 G etc....an easier proposition.
Furthermore reheat is based on US licensed technology, so a potential advocate for Medway would exist in the US.......
In the words of Dick Dastardly "Double drat!"Drats, forgot the TSR.2.

An earlier Marine Spey instead of the Marine Olympus or Marine Medway instead of Marine Olympus?
Dick Dastardly occasionally said, "And treble drat!"
The Spey for F-4K took longer do develop than estimated and the R&D cost was about £50M instead of the estimated £25M.Step 5 - the subscale Medway called Spey finds its way into the Buccaneer S.2, and then into the F-4K
So the twin-Spey Mirage F3 for France, Belgium and South Africa instead of the Mirage F1 and Mirage F3s with 2 M53s for France instead of the Mirage 2000. Have I interpreted that correctly?Step 8 - Meanwhile, in France... SNECMA is doing a good job with Medway, then Spey. By 1962 the subscale engine is licenced for the Mirage III-V; F2; F3; G. Eventually the French derive the M53 out of the Spey for larger twin-engine types. The Mirage F3 greatly benefits from this, screwing both F1-Atar and Mirage 2000 in passing. Belgium takes a handful of F3s in 1973, followed by South Africa.
Wouldn't that also apply to a Medway-powered TSR.2?...but sucks at high speed.
There's no civil Spey for the Trident so development of the military Spey for the Buccaneer can be begun several years earlier. In fact early enough for some of the 20 development aircraft to be fitted with Speys and the 40 production S.1s of our timeline are built to S.2 standard in this timeline.Step 5 - the subscale Medway called Spey finds its way into the Buccaneer S.2, and then into the F-4K
The A-7 prototype flew in September 1965 and the A-7A entered service in February 1967.Step 6 - Allison jumps into the fray, takes a Spey licence for the USAF A-7D; the USN likes the idea, ditches the TF30 for the A-7E - and both go TF41. Rolls Royce has now crashed their way into the US military pot of gold.
I'm confused here. Do the F-14A and F-111B have the TF-41 instead of TF30?Step 7 - This snowballs into the doomed F-111B, then into the Tomcat. Uncle Sam learns to appreciate the Spey, in comparison with that TF30 piece of junk. The engine is very welcome as a stopgap before the F100 and F101 - and the troubled F401, making it even more useful to the Tomcat in the long term...
What about a Marine RB.211?If Medway is chosen for the TSR.2 will it also be chosen for Concorde?If....if Government had allowed it RR Medway was the preferred engine on OR.339 submissions, rather than BS Olympus.

In that case the Nimrod's a modified "Big Trident" with Medway engines instead of a modified Comet with Spey engines.Step 1 - DH.121 is not shrunk into the Trident, and give the Boeing 727 a run for its money
I believe the Boeing Submission was originally designed around the General-Electric MF-295 (as was everyone elses, given that it theoretically offered better performance than the TF-30, whilst being smaller) and had to be modified for the TF-30.I'm confused here. Do the F-14A and F-111B have the TF-41 instead of TF30?
If that's the case do the F-111A/C/D/E/F and FB-111A have TF-41 instead of TF30 too? If it is I wonder if the engines on the this timeline version of F-111K would have RR built Speys or Allison built TF-41s.
I believe that Boeing's submission to TFX had Speys. Is that also correct?

Will Dassault still develop the Mirage F1? That is to sell to air forces that couldn't afford the F3? Except that it will have a single Spey engine instead of the Atar 9K-50.
Can the Mirage III/5/50 airframe take a Spey? If will the aircraft that had the Atar 9K-50 in the "real world" have Spey engines in this timeline?
In that case the Nimrod's a modified "Big Trident" with Medway engines instead of a modified Comet with Spey engines.Step 1 - DH.121 is not shrunk into the Trident, and give the Boeing 727 a run for its money
The "Little Trident" was in production until 1978 and the "Big Trident" will be in production until 1984 if it gives the Boeing 727 "a run for its money". That will make it easier to sell the Nimrod on the export market.
It would be an even bigger disaster than the real one. The airframe isn't big enough and the engines are too close to the rear radome.Excellent ! How about the AEW mk.3 ?In that case the Nimrod's a modified "Big Trident" with Medway engines instead of a modified Comet with Spey engines.Step 1 - DH.121 is not shrunk into the Trident, and give the Boeing 727 a run for its money

So all the countries that bought F1 and 2000 in the "real world" buy F3s and in the same quantities. Is that correct? My previous interpretation was that it was only bought by France, Belgium and South Africa.Just the Mirage F3, first with 1*Spey and later with 1*M53.So the twin-Spey Mirage F3 for France, Belgium and South Africa instead of the Mirage F1 and Mirage F3s with 2 M53s for France instead of the Mirage 2000.

OTL F1 was a 0.8 scale F3 shrunk from TF30 to Atar 9k50.
No need for the F1-Atar, F1-M53 nor 2000 if the F3 with a turbofan is doing the job right from 1972.
What do they buy instead of the Jaguar?Step 9 - In passing, the Medway-Spey Anglo-French connection screws the Jaguar out of history; it goes no farther than the AFVG, leading to a Hawk - Alphajet split on trainers.
There were Spey powered trainer/light Attack I think from the Folland stable.What do they buy instead of the Jaguar?Step 9 - In passing, the Medway-Spey Anglo-French connection screws the Jaguar out of history; it goes no farther than the AFVG, leading to a Hawk - Alphajet split on trainers.
Yes!!What about a Marine RB.211?
I agree with the first part of the sentence. However, the "Big Trident's" order book would, rather than might, look healthier than the "Small Trident's" order book. Doubling or trebling the number of Tridents sold would be a considerable improvement on the 117 built in the "real world".I'm not sure a Big Trident would necessarily sell 727 volumes of sales, but the salesbook might look healthier.
I don't see why because the aircraft weren't competing for the same segment of the market. They were complimentary. Trident was competing against the Boeing 727 while the BAC-111 was competing against the Boeing 737 and Douglas DC-9.Ironically a successful Trident might kill off the 1-11 entirely...
I think that an earlier BAC-211 and for that matter the HS.132 or HS.134 entering production is unlikely....but we might get a 2-11 earlier perhaps.
I suspect that the only Diefenbaker that most British people have heard of (and that includes myself) is the dog/wolf hybrid that was in the late 1990s TV series Due South.Duncan Sandys, how we love to hate you passionately. With Diefenbaker. And McNamara. I wonder if there is a picture of these three together - we aerospace nerds could use it as a target to play darts... or voodoo.
Are you referring to the Gnat Mk 5 and its VG variants? As far as I know it was to be powered by a pair of RB.153 engines, but I'm prepared to be proved wrong.There were Spey powered trainer/light Attack I think from the Folland stable.What do they buy instead of the Jaguar?Step 9 - In passing, the Medway-Spey Anglo-French connection screws the Jaguar out of history; it goes no farther than the AFVG, leading to a Hawk - Alphajet split on trainers.
