I know that the RAF did use Lightnings Mk.1 and Mustangs Mk.1 (etc.) but I consider drawing "more British" versions, as copies (more or less) of the famous Spitfire... elliptical wing, modified tail and so on. ;)
(It is now July 1st, 6 am on my side of the planet, the RAF time has come...)
Here are the Supermarine Spitning Mk.1 and 2, VERY long range fighters, ordered in 10,000 copies by the RAF 1942 (before cancellation)...

The short range derivatives Supermarine Spitning Mk.3/4/5 were interesting too, but without major advantage over the Whirlwind.

The P-51C, even with Merlin engine and Malcolm Hood, was still "not British enough", argue the RAF generals, so the Spitstang was developped:

After hard discussions between engineers and generals, North American admitted that, while the Mustang wing is the best, the Mustang tail may not be "how a tail must be"... so 2 British versions used Spitfire tails:

The RAF top general said: "OK for your Lightning heart and powerful nose, but for the rest: use Spitfires!".
This was built, then engineers said: linking the tails made it more solid.
This was built, then engineers said : decreasing the tailplanes size would give more speed.
This was built. Was it ? ;D

The English Mustang, the best one (Mk XIII?), used a Spitfire bubble canopy and wing radiators:

You're definitely onto something. Considering the Mustang also began life with Allison power egg, one can only wonder if the Lightning could have been equipped with the same even in real life? Simple mechanical supercharger instead of the complex and expensive turbocharger, maybe that would have made Lightning more viable economically and operationally (to be manufactured in greater numbers, adopted earlier, staying in service later, supplied to other Allies)?

But... without the huge chargers on engines, no more need of booms, or... something like a drawing I made years ago: ;D

And the top general of the RAF said: "We have not ordered the Twin-Spitfire because, as long as twin-engine fighters are concerned, we prefer the Mosquito", so Lockheed proposed the Lightito Mk.1, 2, 3, but without success either.
(https://www.whatifmodellers.com/proxy.php?request=http%3A%2F%2Fwww.kristofmeunier.fr%2FP38eclairT_dk.jpg&hash=e94860044e68e8013472d66f53e4982c9cbaf042)
Another Lockheed proposal for the RAF: Whirlning Mk.1, 2, 3. No success either...

In 1945, the RAF top general argued: "we have already twin-boomers, so Lockheed must use De Havilland Vampire's double tails!". This was designed but not ordered (too much expensive):

The US ambassador proposed a fair deal: the US Navy will buy British ships only and the RAF will buy American planes only: Horsning, Lancasning, Metning (replacing Horsa, Lancaster, Meteor), all right? The answer has been no, alas (for twin boom glory to reach eternity). :-\

for this Mustang's design, I see no technical (nor operational) justification, this seems a commemorative airplane...

Hehehe, very good Tophe. :thumbsup:

There was no
Allison power-egg, every installation was different. The Brits and Germans used
the power-egg concept, the US did not.
A single stage mechanical supercharger was a standard feature of the Allison V-1710, the only variant
that didn't have it was the airship powerplant version.
Turbo-superchargers are no more complex than any other centrifugal supercharger, in many ways
they're simpler as, in the majority of cases - turbocomponds being the exception, there is no
mechanical connection between the turbo and the engine. No drive system, thus no gearing issues,
quill shaft failures, no engine hp being absorbed to drive the supercharger, etc.
Ahem, I know that here you are damned what-ifers, stupid dreamers, so let a True Historian like me tell you The Very Truth, undoubtedly!:
The RAF, ordering the Lightning Mk.1 refused the turbocharger, arguing it is providing "not enough" bonus in performance, so was designed for them the P-38 with Very Super Charger, for a true boost at high altitude:

;D ;D ;D :thumbsup: :thumbsup:
Thanks!
And the P-51UJ should have been bought by the RAF, with its wing like "normal/swept/forward-swept" (NSFS?), but no order came, surprisingly:

LOL! ;D
