Best Allied Nightfighter: P-61, Mosquito, or Hellcat?

[kitfox]

Hello. This is my first posting. I read with interest an extensive evaluation of WW2 aircraft at Elgin Field, Florida throughout 1945. This testing included flying competition between all current USA production fighter aircraft. (P-51D, F4U-4, P-39Q, P-40N, P-38L, P-47D-25, P-61B, F6F-3, FM-1, and P-63) It also included some pilots from Canada and the UK, and a few foreign aircraft (Hurricane, Spitfire, A6M2, Bf-109E, Mosquito NFII). The report listed the result of the flyoff between the P-61B and Mosquito NFII "inconclusive", the only flyoff so listed. There was interest by the Americans to abandon the P-61 and procure only Mosquitos for the nightfighter role. My question is:
What was the best nightfighter Allied aircraft; P-61B, Mosquito NF-XIII, or F6F-5N?
Thank you.

The Mosquito NF XII for me most, but this isn´t a general answer.
It very much depends on the thread scenario and I must admit that the P-61 could proove more able to development changes in some respects.

I should think the Mossie, for one or two reasons that I can think of offhand - higher speed: about 612kph/380mph compared to 589kph for the Widow (sorry, but my docs on the Widow are in German, with metric measures. It would in fact be fairer to compare the Widow, which entered squadron service in March 1944, with the Mossie NF. Mk30. This entered service in 1944, and had two-stage Merlin 72s or 76s, and a speed of 424mph/682kph.

The Mossie was not just faster, but significantly more manoueverable (is that how it's spelt?), too.

It was cheaper and easier to build, needing far less in the way strategic materials.

And it had a not dissimilar punch; although it had lost the four .303 Brownings, the four 20mm Hispanos were the same. Do not forget that the turret was not carried on many P-61s, having proven to be unreliable.

Hellcats? As night fighters? Forget it. A single seater equipped with AI, at that time, gave the pilot too many things to look at at the same time. Just flying at night was difficult enough, plus keeping an eye on navigation - you never know when your d/f kit is going to pack up - without having to keep your eyes on a second set of dials for the AI system. And 6 .50 brownings do not pack enough punch to do significant damage to a bomber with just a few hits. Because at night, that's what you're going to get.

I think you've forgotten the Beaufighter, as well; not as advanced as the Mossie, but greatly loved by the people who used it. 4x 20mm Hispanos and 7x .303 Brownings...

Mossie for me - ndicki has mentioned the main reasons for my decision.

Mossie was a better performer but I would look at this by theater. In the SW Pacific I'd go with the P-61. It was tailored for the role and had nice round reliable engines. We could argue which aircraft had the better radar, I think in reality they were about the same. The Mossie had an edge on firepower but it's wood structure could be troublesome, especially if continually repaired.

[the lancaster kicks ass]

this's already been covered and apart from CC and wmaxt who will swear blind that the P-38 is the best most will agree to it being the mossie NF.XXX, and whilst i agree the Beau does deserve a mention she wasn't the best, better than a hallcat though ................

[FLYBOYJ]

The Hellcat was a qucik fix - the F4U-5N was probably the best Naval recip single engine night fighter.

[DerAdlerIstGelandet]

I voted for the Mossie and she was obviously a better aircraft than the other aircraft post but I agree with FBJ that for the PTO the P-61 would be better only due to construction. Wood would rot easier in the PTO.

As it did

Early Mosquitos in the Far East delaminated due to the glue used, until it was changed.

[Hurricane33]

how come no one mentioned the messerschmitt bf 110?

[Gnomey]

Because it is best Allied night fighter...

So no Axis ones in the poll...

This from Wikipedia...

"Training of P-61 crews commenced in a variety of ways. Several existing night fighter squadrons operating in the Mediterranean and Pacific Theatres were to transition directly into the P-61 from Bristol Beaufighters and Douglas P-70s, though most P-61 crews were to be made up of new recruits operating in newly commissioned squadrons. After receiving flight, gunnery, or radar training in bases around the U.S. the pilots, gunners, and radar operators were finally combined and received their P-61 operational training in Florida, for transfer to the European Theatre or California, for operations in the Pacific Theatre."

The 422nd Night Fighter Squadron was the first squadron to complete their training in Florida and, in February 1944, the squadron was shipped to England aboard the Mauritania. The 425th NFS was soon to follow aboard the Queen Elizabeth.

Upon arrival in England, the two squadrons found they were without any aircraft. The crews passed the time by flying the base's Airspeed Oxford and Cessna C-87, as well as visits to local towns and occasionally to London.

The situation deteriorated in May 1944 when the squadrons learned that several USAAF Generals believed the P-61 was too slow to effectively engage in combat with German fighters and medium bombers. The RAF shared this view, based on a single P-61 they had received in early May. The RAF championed switching to their De Havilland Mosquito Mk. XVI. Several pilots in the 422nd NFS threatened to turn in their wings if they weren't permitted to fly the "Black Widow." At the end of May, the USAAF insisted on a competition between the Mosquito and the P-61 for operation in the European Theatre. RAF crews flew the Mosquito Mk. XVI while crews from the 422nd NFS flew the P-61. In the end the USAAF determined that the P-61 had a slightly better rate of climb, and could turn tighter than the Mosquito. The RAF disputed these claims and continued to push for the use of the Mosquito, but the P-61 was considered the victor. In later tests conducted by the manufacturers, the two aircraft were actually found to be very similar in performance, with no clear advantage for either aircraft.

As I posted here before, while the light wood structre of the Mossie was its strength, wood could be real troublesome in the field. Those working with it had to be well trained and some of the repair operations required a clean temperature controlled environment, something not readily available in that day. An aluminum structure aircraft could be repaired almost anywhere you could bring tools and possibly shop air for a rivet gun. Also aluminum structures were a lot more forgiving if the repairs weren't of the highest quality, not the same for wood....

Actually, the AI was the same - AI Mk X, which was the British built US SCR-720.

[syscom3]

I thought the roll rate of the P61 was superior due to the "zap flaps".

There was an occasion in New Guinie where a P61 actually turned inside a Japanese "sally" which wa pursuing it, and maintained the turn through several complete circles. This was an accomplishment of sorts.

Before you make stupid questions like that please read the title of the the thread. Was the Bf-110 used by the Allies...
