I realise these are early post WWII aircraft but I think this may be informative.

There is much misinformation and misplaced bias on the internet about comparisons between these two aircraft. Most are easily disproven by basic physics, aircraft specifications, and actual aircraft performance tests. A lot of information came to light post the USSR (i.e. the complete debunking of the 12:1 kill ratio of the USAF- revised to just 2:1 from official Soviet 'Quartermaster' Bureau figures and squadron records) and also in newly discovered archives. When it comes to commentary and data- i will take data every time -(an occupational of being a former military aviator and more recently a university lecturer teaching BSc Aerodynamics and Systems to aspiring pilots)

Bias about the Meteor Mk 8's performance is often based on the artificially poor performance of the RAAF's 77SQN F8s in Korea against the MiG 15.

In reality, a major part of the wartime air-to-air combat disparity is that the Aussies from 77 SQN had been flying exclusively ground attack in CAC built P-51 (F-51 by then) Mustang since their arrival, and not only had to convert onto a jet (a completely different way of flying) but had to train in bomber escort and how to use a Meteor's strengths in air combat, a task that would take a normal peacetime squadron probably a year of training. It's a bit like stepping out of an A-10A and into and F-35 and expected to fight it effectively within a very short period.

A series of trials between an F8 and an F-86A that took place at Iwakuni in May 1951 showed the Meteors obvious lesser speed (Mach 0.82 at altitude) but maximum speed is only ever used for attach or escape manoeuvres so it is not a useful as it sounds. Following the merge, The F8 proved that it could outturn and outclimb the F-86 allowing it to re-engage and could in many respects, dictate the combat once a slashing attack was avoided.

WGCDR Bill Simmons (RAAF) noted that he was very disappointed in the lack of training they received about the F8s strengths. He said "Had we been operating at its optimum height of 20,000', below the contrail layer, (USAF Sabres often operated at 25-30,000' for the same reason) the attack could be detected (MiG 15s with their higher ceiling were well known for leaving distinctive contrails) and they could have used the F8's superior zoom climb to turn into the enemy and either defeat the attack or draw them in to a turning fight where the Meteor was far superior.

After some difficulty and a few victories over MiGs, 77SQN RAAF while struggling to learn how best to fly and fight the F8, 77SQN was switched to ground attack where they performed extremely well.

The truth is that the Meteor F8 was a much more capable fighter than it has been given credit for. It was not that much slower than the MiG 15 if we use 'peak' figures. The 585mph often quoted for the Meteor is a little misleading, (people mix low altitude mph vs TAS vs Mach number) as this was at sea level in dense, thick air. In fact an earlier F4 actually held the world speed record of 616mph at sea level in 1945. (At the same altitude, captured German performance charts showed the Me 262 could manage just 490mph)

The F8 was capable of Mach 0.82-84 at altitude with a VNE of 0.89. For a first generation jet built without the benefit of the German high speed wind tunnel research captured after the war, this was pretty impressive

Despite its swept wing, the MCrit of the MiG was 0.82–0.85 and the Meteor Mach 0.82-not a big difference. The MiG was transonically unstable in a dive (as many pilots including Chuck Yeager) found to their discomfort or ultimate cost, and oilots were warned not at attempt to approach its VNE, so its primary escape manouevre could be terminal.

The MiGs first generation swept wing design (with its less than optimal aerofoil profile) had to be ameliorated by large wing fences to prevent excessive spanwise airflow and it would experience tip stall and depart in a tight turn. Soviet squadron records show that many 'spinning' MiG 15s that were claimed as victories by eager USAF pilots actually recovered and returned to base, chastened but unharmed.

The MiG 15 typically used it's speed and altitude advantage (thanks to its copied British Nene engine) in common slashing attacks and avoided turning fights (unless piloted by experienced Russian pilots) but if a Meteor saw it first and turned aggressively into the merge, the MiG would have no hope in a turning fight, as the Meteor had a wing loading of 44.9 lb/sq ft compared to 60.7 lb/sq ft with an almost identical thrust to weight ratio.

Again, the MiG did have a superior ceiling and rate of climb to the Sabre and Meteor thanks to its VK1 (copied British Nene) engine but that only gets you so far.

The Meteor had better fighter armament in the 4 Hispano 20mm with a higher muzzle velocity (880m/s vs 660 m/s for the NR 23 giving a much flatter trajectory and so better accuracy (the MiG was designed with heavier armament for shooting down bombers).

In short, a properly trained F8 pilot with good tactics and situational awareness and using the strengths of his aircraft, would have a very good chance of dispatching a MiG 15.

Hi,
My understanding is that the operational wartime Welland Meteors contemporary with the Me 262 had a SL speed of 415mph. Also, the later 606mph was post war with Derwent 1 and the 616mph was later with the Derwent V, all the post-war speed record attempts with tweaked airframes and engines. Of course, these post war records were highly deserved, the engine development in particular advancing at a high rate.
I think Eric Brown commended the Wartime Me 262 at the time, he then having flown all the operational combat jet aircraft of the WW2. I think Brown said that the 262 was the foremost combat aircraft of WW2, with a tactically useable limit of M 0.8.

With the limitations relating to its maintence problems, the Me 262 would have been a sort of WW2 F-35.
 
There can be little doubt that a Welland Meteor would be easy prey for a 262. However I think I am right when I say that the Meteor III came effectively in two batches, the second having a redesigned nacelle mounting which had a much higher performance, just under 500mph. This would have been a serious threat to the 262.

We need a Meteor specialist to give the details.
The Meteor F.3 initially had the Welland engines. At some time, these engines were superceded by the Derwent I engine with some improvement to performance.
At some other later time, the engine nacelles were lengthened with a performance improvement.
There doesn't seem to be a clear definition of any or all of these changes and the performance or whether they were deployed before the end of WW2.
In view of the large differences in performance of these early versions of Meteor "F.3", it would be interesting to know the precise standard and performance of the aircraft actually deployed in WW2. This information would also help with understanding of their limited operational impact.

Cheers

NOTE I have added the information for the MiG-15bis to my post#5 above. The MiG-15bis values are from a Soviet 1954 Pilot's Flight Manual for the MiG-15bis. The primary(I think) difference in weight compared to the original MiG-15 production model is due to the MiG-15bis having an ejection seat fitted, plus detail strengthening of the airframe.

The MiG-15bis entered production sometime in 1950(I think).

Quite right. That's the empty weigh W/L for the prototype F1 . Loaded weight in the 30s. Copy error. Mea Culpa. F8 was 44.9 lb/ sq ft. MiG15 60lbs/sq ft - still a significant difference in performance (other than top speed) climb and turning ability as demonstrated with is nearest analogue the Sabre at Iwakuni. I will correct my post.

Soviet pilots did not consider the Meteors as a serious threat and mention this in their memoirs. Furthermore, no combat losses were recorded for the 64th Fighter Aviation Corps in engagements with the 77th Squadron. In general, it is difficult to say who the Meteor pilots fought against in 1952 and 1953 - most likely Chinese MiGs. At least, I know of only one mention of combat with Meteors in Soviet sources from 1952, namely on October 2, 1952. The training level of Chinese pilots was significantly lower than that of Soviet pilots, although the Soviet 97th and 190th Fighter Aviation Divisions, which arrived as replacements in early 1952, were somewhat less well-trained than the 303rd and 324th Divisions. And it seems to me that the pilots of the 77th Squadron were simply lucky that they were no longer used as fighters - their losses would most likely have been even higher. You can argue endlessly that the Meteor wasn't all that bad compared to the MiG-15, but I'm afraid that would just be creating a new myth.

I have to agree that the Meteor wasn't equal to the Mig 15 when properly flown. Pretty much everything was against it apart from the turn
 
re

NOTE that the wing loading of 60 lbs/sq ft is for the MiG-15 with 2x 158 USgal drop tanks - the wing loading for a clean MiG-15bis is only 49.3 lb/ft2, and the basic MiG-15 would be a bit less. This is of course still a significant difference vs the 41-43 lb/ft2 of the Meteor Mk.8.

Also, see my post in the other thread "Dogfight: Me 262 vs. Meteor" re the RAAF view of the Meteor and MiG-15.
 
British summary of the topic, reporting from a visit to Korea back to the Air Ministry (via British Embassy in Tokyo) 10 May, 1952:

The facts are that in a fair fight a well handled Meteor should be able to avoid being shot down by a MIG 15 at low to medium altitudes. On other hand a MIG 15 properly handled and alert should never be loitering about in such a position that a Meteor can shoot it down for the following reasons. The MIG 15 can and does normally fly in the combat area at high cruising speeds which are in excess of the maximum permissible mach. number of the Meteor. In equal combat the MIG 15 can always rapidly pull away from a Meteor in level flight or climb away at will. Thus the MIG 15 can always dictate the fight and it has a superior performance which should make it impossible for a Meteor ever to shoot it down in equal combat.


Very interesting bits contained in a report from Air Vice Marshal Bouchier after a visit to Kimpo and 77 Squadron RAAF, 19 Sep, 1951:

...

Morale. Above mentioned officers all agree that morale in the Squadron was "good". My personal assessment is that morale is something less than good and that some action must be taken to prevent further deterioration. This loss of morale arises from many factors. Wing Commander Steege appears to be an excellent officer but understand he does not fly regularly if at all with the Squadron. He is emphatic and loud in his statements that the Meteor is hopelessly outclassed by the M.I.G. 15 in air to air fighting. This attitude which of course does not help morale is however largely governed by his natural desire to prevent his Squadron from being badly beaten up and decimated with relatively so few Meteor aircraft behind him and with his present difficulties in getting replacement pilots from Australia. None of his Australian pilots or replacements appears in any way to have been hand picked. This is a pity. On the same airfield I spoke with a Wing Commander and Squadron Leaders of three American Squadrons of F 86 type Sabre Jet fighters. Every American pilot in these three Sabre Jet squadrons has been hand picked in the United States for the job in Korea and consequently they are experienced and of very high quality. Thus although the Australian Meteor pilots are close friends and work in greatest harmony on the same airfield with the pilots of the American Sabre Jet Squadrons, nevertheless I imagine the ever present reminder of the better performance of the American F 86 Sabre Jet fighter in air to air fighting with the M.I.G. 15's plus the greater experience and possibly higher quality of the American pilots, has perhaps a depressing effect and does not help much to raise morale in the Australian Squadron.

Flight Lieutenant Scannell of Eastern Sector of Fighter Command and Flight Lieutenant Blyth of Training Command are the two remaining members of the team sent out here from England to convert this Squadron on to Meteors. Both these officers are due to return to U.K. forthwith. I saw only Flight Lieutenant Scannell. In the absence of Squadron Leader Wilson I judged Scannell to be the best pilot in the Squadron and his morale is high. He says he can shoot down a M.I.G. 15 and very much wants to remain with the Squadron to complete a full operational tour. I strongly recommend that Scannell should immediately be authorised to stay with this Squadron and Blyth also if the latter volunteers.

To illustrate the different and somewhat shaky morale in this Squadron. Flight Lieutenant Scannell said that with pilots of equal ability in both aircraft "below thirty thousand feet no Meteor pilot should ever be shot down by a M.I.G. 15 unless the Meteor pilot makes a mistake because the Meteor has better or at worst equal manoeuvrability". Whereas the other Flight Commander Flight Lieutenant Murphy said "no Meteor pilot can escape being shot down by a M.I.G. 15 at all altitudes". Both however agreed that two M.I.G. 15's have the tactical performance ability to attack at any time and every day a squadron of Meteors and that the M.I.G. 15's would shoot down, in the general dog fight dispersion which ensued, one or two Meteors regularly without loss to themselves.

In a fair amount of fighter sweep operations the Meteors have however so far only had two separate encounters with M.I.G. 15's. In these two engagements the Meteors lost one shot down and two heavily damaged for no damage at all to the M.I.G. 15's.

The main complaint of the Meteor pilots is the very limited mach (repeat mach) number of the Meteor and to much lesser extent the fact that rearward vision of the Meteor is extremely bad and dangerous. No backward vision at all between five and seven o'clock. The mach number of the M.I.G. 15 is unlimited. That of the American Sabre Jet is zero point ninety five. Whilst the Meteor mach number is zero point eighty two.

Thus in the air fighting area the M.I.G. 15's normally cruise (repeat cruise) at not less than the mach number of the Meteors namely point eighty two or slightly in excess of that number with the result they say that every advantage that the Meteor in theory is supposed to have over the M.I.G. 15 is automatically annulled. For example. If a Meteor finds itself at five thousand feet directly above a M.I.G. 15 and heading in same direction. The Meteor can not close the range because although the M.I.G. 15 might even be caught by surprise the M.I.G. 15 is already cruising at a mach number in excess of that of the Meteor. Thus the only time the Meteor can attack a M.I.G. 15 other than head on is as follows. When the Meteor is above the M.I.G. 15 as described above and the M.I.G. 15 starts a turn. The Meteor can then cut the corner and get into firing position provided the M.I.G. 15 does not stop turning and does not ascend or descend.

Zero point eighty seven is the absolute mach number of the Meteors. Beyond this number the Meteors become uncontrollable. Thus when the Meteor attempts to close in upon a M.I.G. 15 which is already flying at or slightly in excess of point eighty two mach number the margin available to the Meteor is extremely small and the Meteor pilot is always in danger of losing control of his aircraft at the outset of an engagement. This happened in one of the engagements as follows. A M.I.G. 15 sailed past just below and to one side of Squadron Leader Wilson at a high mach number. Probably as a decoy. Wilson chased after it. Wilson's number two followed suit to protect Wilson's tail. But Wilson's number two exceeded at once zero point eighty seven mach number and his aircraft went out of control and fell many thousands of feet. The pilot wrenching his back in trying to regain control again which however he eventually did successfully. In such circumstances the uncontrollable Meteor is not a sitting duck but if the M.I.G. 15 follows it down the latter can of course shoot the Meteor down at the moment when control is regained and the pilot is wiping off the sweat as he flies straight and level. Regarding Squadron Leader Wilson. He was jumped on by another M.I.G. 15 which hit his Meteor with two thirty seven and two twenty three millimetre shells but Wilson brought his Meteor back safely to base although extensively damaged.

...

The Meteors have not as yet registered any hits on M.I.G. 15's in combat. All bursts having been fired by necessity at ranges in excess of fifteen hundred yards. The gunnery of M.I.G. 15 pilots is definitely inferior to gunnery of American pilots in Sabre Jets which are able to close to more effective range than the Meteors. ...
 
"He was jumped on by another M.I.G. 15 which hit his Meteor with two thirty seven and two twenty three millimetre shells but Wilson brought his Meteor back safely to base although extensively damaged."
If anything, one advantage of the Meteor is its survivability. Hit by 2x37mm and 2x23mm, it landed safely. As I remember, Wilson flew back with his canopy partly destroyed and without instruments.
Reminds another survivor - Royce Williams in his F9F-5 after one or two 37 mm hits.
