The whole Empire? New Zealand, Australia, and India would be speaking Japanese and Canada would've eventually been absorbed by the USA, meaning we'd all be speaking English with a Texas drawl.Gemhorse said:...The British Empire would be talking German now if the Spitfire was 'over-rated'...

Spitfire.
Good, but many planes were better in most categories, such as the La-7.
Nonskimmer said:But why argue it? The Merlins powered the Lancaster as beautifully as they would have any fighter, and there wasn't exactly a shortage of them. Fighters either, for that matter.
RG_Lunatic said:The B-17 could carry 6,000 lbs of bombs to a target about 1100 miles away at 25,000 feet. However, for such a long range mission typcially only about 4000 lbs were carried to provide more form-up time at the start of a mission.
The Lancaster could carry about 12,000 lbs of bombs to a target 1100 miles away at about 15,000 feet, or 14,000 lbs of bombs at about 10,000 feet.
If the B-17 were to limit its altitude to 15,000 feet and not have to form up into a bomber box, it could carry 8,000 lbs further to a target further than 1000 miles away.
So yes, the Lancaster did carry a bigger bombload, but it also was much less durable and would have been slaughtered much worse than the B-17 had it undertaken the same daylight missions.
Some other points to be made:
First the specs of the aircraft:
The B-17F had four Wright R-1820-97 Cyclone radials rated at 1200 hp takeoff, 1000 hp @ 25,000 feet, 1380 hp WEP for brief intervals. Max. speed was 299 mph at 25,000 feet, 325 mph at 25,000 feet (war emergency). Cruising speed was ~200 mph. Climb to 20,000 feet could be attained in 25.7 minutes. Defensive armament: 1 x .30 M2 mg + 11 x .50 M2 hmg's. Production: ~12,750 Sorties flown: ??? Bombs dropped: 500,000 - 640,000 tons in the ETO (sources differ).
The Lancaster Mk.III had four Rolls Royce or Packard Merlin 28 or 38 inverted-Vee, rated at 1460 hp (no WEP figure given). Maximum speed was 281 mph at 11000 ft. Cruising speed was 227 mph at "optimal cruising altitude" (?). Climb to 20,000 feet could be attained in 41 min 24 sec. Defensive Armament: 8 x .303 Brownings. Production: 7377 Sorties flown: 156,000 Bombs dropped: 608,000 tons HE plus more than 51 million incendiary bombs.
Of the 7377 Lancasters (there may have been a few more but not many) at least 3460 used the American built Packard Merlin, and many RR Merlins used some American built parts. The Lancaster had about 1000 HP more than the B-17, and almost half of them were using American built engines which could have been used in a B-17 or B-24 variant which would have made them substantially faster.
Which brings up another point. Neither the B-17 nor the B-24 used an engine which could have reasonably powered a fighter. It could well be argued that the production of Lancasters cost the British/Americans something around 8,000 Spitfires, 8,000 Mustangs, and another 6,000 Mosquitos! Just food for thought.
