Good point. The Lancaster and Halifax were in production and had been
operationally proven by the time the Warwick started to appear. I
presume it clung on due to some production commonality with the
Wellington plant which allowed Vickers at Brooklands to cling on to
stubbornly turning out at least a few of their own design before the
MAP could bear down on them and get them to change over to Lancasters.

It really didn't do anything that
other airplanes did better.

Or even as well.

By the time it came off the line, the
RAF's Medium bombers were teh B-25 and B-26, (Excuse me, Mitchell and
Marauder) except in those parts of teh world where the Wellington was
still viable. The Oceam Patrol stull has being handled by the
Catalina, the Sunderland, the Liberator, the Fortress, and the
U.S. Navy's patrol forces. So why all the effort? Was it an
Industrial Policy Effort to keep Vicker's Geodesic Structures skill
up to par, in case there was an urgent need to rebuild the R-100?

Probably due to all the expense and effort of getting the original
machine tools on line to produce the Wimpey airframes. Writing off
that stock would have been painful after all the problems they had in
1937-39 actually reaching Wimpey production targets.

As for the Stirlig's wing thickness. It's not all that bad, really.
It's just, lke the B-24 and the Davis Wing, that they stuck it onto
that godawful fuselage. (Which ended up being mainly empty space,
anyway.)

It's waaay thicker than the Lib wing - the wing root is practically as
deep as the fuselage. I suspect, knowing wartime working practices at
Shorts, that t was used as a bunk for snoozing workmen during
construction.

It's not like Critical Mach Number improvement is going to be
high on the list of Stirling Improvements. As for teh altitude
perfomance of the Hercules, in the VI and XVI models, they really
weren't all that different than the corresponding Merlin XX-24 series,
epsecially in terms of cruise power.

The Stirling III and Halifax III still seem to have a major
differential in terms of operational ceiling, which I can only put
down to structure weight and the wing.

A better operational ceiling comparison would be between the Stirling III
and Halifax II, as the latter has the original 98(?) foot wing (some
sources claim that early Halifax IIIs had the original wing; I don't have
enough info to say). The Halifax II is still better but not much, and I
expect the difference is largely due to the lower weight, and maybe the
drag of the Stirling's nose turret.
