Military Aircraft that should have never been built?

The Wellesly was actually quite a good aircraft. It had superlative range, flying from Africa to northern Australia without stopping. What it lacked was a fuselage bomb bay 'cause Barnes Wallis had not worked out yet how to create one. The Wellesly was a learning step towards the Wellington and later Vickers' bombers. It was rugged and it did what was asked of it, what else could be expected of it?

Lockheed in the '80s had proposals for a KS-3A tanker variant....and all those S-3s are still in the desert, gathering dust and cobwebs. No doubt Lockheed-Martin's got the plans to convert some to tankers (they'd be fools not to).
Despite what a lot of people think, the last S-3 Viking was manufactured 42 years ago. And after the retirement of the KA-6, they were worked hard as tankers. Lockheed was able to extend their service lives, so some of those airframes still have usable life, but the Navy seems uninterested in reactivating them
 
I have been reading these posts on the thread. As a non American I have to come to the conclusion that the USA should not, apparently, have made any of the warplanes made in OTL.
 
The North American Rockwell NR-356 should never have been selected for the VFAX program. Instead, the USN should've chosen the Convair-General Dynamics Model 200.
 
A couple of comments:

1. The Heinkel He 177 was hamstrung by the fact there wasn't enough money spent on fixing the engine overheating problems with the DB 610 engines. In fact, they actually modified one He 177 in early 1944 based on the analysis of known engine issues, and that modified He 177 actually functioned perfectly. Had the fixed that problem in 1942, the He 177 could have gone on to a fairly decent combat career.

A heavy bomber with 4 nacelles for 4 engines makes far more sense than what He 177 used.
BTW - DB 610 performed as advertised, it was DB 606 that was prone to spontaneous fire.

2. The Boulton-Paul Defiant was really hamstrung by the fact the plane was limited by the early Marks of the Merlin engine. Had the Defiant been upgraded to use the Merlin 45 or 61 engine, the plane would probably been a lot faster and with a redesigned turret designed to handle more powerful guns, could have been a potent anti-bomber interceptor.

Defiant, Hurricane and Spitfire in 1939-mid 1940 shared the same engine - Merlin III, difference in every-day service being that Defiant was a death trap when enemy fighters are around, unlike the other two. Due to the need to carry the turret, Defiant was wider (= draggier) than Spitfire, and heavier than either of other two. Add the drag and weight of turret, and speed and rate of climb are in problems. By 1941 (= Merlin 45 available), we have Spitfire doing 370+ mph with two cannons, and Hurricane IIC was making 320 mph with 4 cannons. Turret that can handle bigger guns = another money sink. Defiant simply does not offer anything over the cannon-armed Sptfire and Hurricane, it will be more expensive, it will require twice the crew, and it will be bad against fighters (German bombers are already fair game for any Hurricane, let alone Spitfire).

RAF has (an unlikely) surplus of Merlin 61s in 1942-43? Install them on actually useful aircraft besides Spitfire, like Mosquito, Lancaster, or re-engine the Mustangs.

Logistics. The USAAF concentrated the B-26 in Northwest Europe and the B-25 in the Med and Pacific. Same as B-17s were the Primary heavy bomber of 8th AF while the 15th in Italy was primarily equipped with B-24s as were the Pacific commands (which really needed the longer range)

Some analysis was done in making the decision. The B-26 was considered a better choice for the higher threat Northern Europe theater (faster, more maneuverable) while the B-25 had a longer range desired for the over water missions in the Med and Pacific.
The Marauder also had a problem damaging prop blades on the rough Pacific strips. The Mitchell had more clearance so it suffered less damage.

Most of the gear in the B-29 was pretty much revolutionary, and built in a hurry, never a good idea, but it was the only bomber the US had that could have carried out long range bombardement of Japan. So there's that. And it did fly well.. when the engines held. As for being "fortunate that it did not face particularly heavy opposition in its combat career" that can be said of any WWII bomber: none would hold out on it's own. At least the guns on the B-29 had proper fire control.. As for Korea... the Migs were at least 2 generations past the B-29 original design. You can't really compare them!
TheMiG 15 was specifically designed to kill bombers like the B29.

This is actually a myth. American and Japanese pilots, in the early stages of the war, were equally well trained. And once the USN worked out the tactics, even the supposedly inferior Wildcat could tear through a Japanese Zero formation. The problem was, early in the war, that the USN did not believe that the A6M was in service on Japan's carriers. They were expecting to still fight Claudes, which the Wildcat could literally fly circles around. So the Zero came as a shock thanks to Naval Intelligence missing it. Once American pilots saw the Zero's handicaps, they very rapidly worked out how to beat it (Thatch weave, Boom and Zoom).
The IJN had the best pilots in the world in forty one and forty two. It was incredibly picky about picking pilot candidates and then washed out over ninety percent of the few they picked. Read Samurai by Martin Caiden and Saburo Sakai for a description of the training.

This one at least, I think is just a simple misunderstanding. The Merlin was not fit for mass production using American methods until it was redesigned (minimal handfitting or craftsman involved, being machined to far tighter tolerances than in the UK), whereas it was being mass produced in the UK without problems because the UK had far more skilled craftsman who could do final fitment of the engines by hand.
“File and fit”production isn’t mass production in my book. It takes far longer and is less accurate than properly designing and producing parts to fit. Needing scarce skilled craftsmen on a production line wastes manpower and man hours.
 
There's nothing wrong with the Wellesley. Fantastic range, decent bombload for the time and tough as old boots. The only thing it possibly needed was another engine.
A twin-engine Wellesley is effectively a Wellington.:)

Which could have been a very good thing.

The Wellesley was started a year before the Wellington, the prototype's first flight was a year earlier than the Wellington and it entered service 18 months before the Wellington.

The Wellesley entered service the same month as the Battle and two months after the Blenheim.

This old canard! The Merlin was designed for mass production and was fully mass produced in the UK such as by Ford in Manchester. Original orders were in the low hundreds and were made by Rolls Royce who had skilled staff and insufficient orders to fund full mass production so used the skills they had. The principal difference between US and UK production was the projection of the drawings as the UK used European views and the USA used their own views. A bit like today where the USA uses Imperial units and the rest of the world uses metric. Merlin development was done by Rolls Royce and development engines were hand fitted but UK production was all mass produced. Packard's occasionally got ahead of the game as they got new developments into their production as new lines came on stream whilst UK production maintained existing models to keep the flow going.
 
Merlins were produced at four separate plants in the UK. These were RR at Derby, RR at Crewe, RR at Hillingdon Glasgow and Ford at Manchester. Of these Crewe and Hillingdon Used British mass production standards, where tolerances were such that some parts would need fettling to fit, Fords used higher tolerances with more single operation/use machines. One advantage of Crewe and Hillingdon over Ford's at Manchester was that the RR factories could just get their operators to adjust their machining to accommodate changes to the engine for a new Mark or other development. Whereas Ford could spam out the same engine in the thousands but had to basically change the machinery to make any changes to the production line. Meanwhile the Artisan production by highly skilled individual machinists at Derby could build prototypes and batches of specialized engines as required which no other existing facility could do at the time. In a wartime environment IMVHO the British government got it about right with RR on how to get the most benefit from what was possible.

Never underestimate the value of a flexible, pragmatic approach. If the RLM had looked at the early problems with the He177 and decided to produce a simpler version with four single engines (maybe by nicking the nacelle design off the He111) and no dive bombing requirement, the Luftwaffe could have had an effective four engined bomber certainly by 1943, maybe sooner. The failed development of the OTL He177 could have continued.
 
Having recovered both wrecked Manchesters and Lancasters, I am please that no Luftwaffe bod made the connection and suggested the same fix for their problems with the He117 as suggested by oldiornside above.

Far too late for that. Besides, it would mean having the nazi leadership admit their idea was bad, and the enemy's good...

They may have been the best, but it was by a very small margin. There wasn't this huge gulf between American and Japanese Naval Aviators that some seem to think there was. Both services were highly trained and thoroughly professional.

Two of the main problems with the IJN were the same as the Luftwaffe: their training programs and their mania for not rotating pilots in and out of active duty. German and japanese veterans flew untill they died, regardless of time in duty; meanwhile, training was carried out by instrutors that(for the most) had little combat experience. Alied pilots were rotated back, and many went on to training units, to pass on what they had learned. This meant that new alied pilots had far better tactical training in middle/late war than Axis pilots.

But there were 10 US pilots for every IJN pilot.
