Not intending to derail the thread too much, but does anyone have any credible evidence of the alleged mock dogfight between the He 280 and the FW 190? I have a book on the He 280, which mentions a race between the two, but no evidence of mock battles. From what I have read over the years, the He 280 bested the FW 190 in every aspect of dogfighting, not just outright speed. It was supposedly held in front of high ranking Nazi's to boost the possibility of being awarded a production contract, which of course never came. The He 280 was completing pure jet flights before the Me 262 prototypes were barely getting airborne with a Junkers piston engine. It already had tricycle undercarriage, an ejection seat, and three 20mm cannon fitted in the nose, although it remains unclear if any actual gunnery practice took place. There were plans for a single fin and rudder and improved armament,and it was designed purely as a fighter, with no indications of having any kind of bombing capability. The problems with the engines sealed its fate, and it would have never been ready or reliable enough to enter combat in any numbers, so the "what if" scenario is pretty much dead in the water. I still consider it one of the most elegant aircraft ever made, classically beautiful and unique for its time.

The RLM had the "golden egg" dropped in their lap in 1939, when the He178 took to the skies, but they dismissed it's significance as a technilogical leap (and potential military value).

Had they embraced it's potential, and provided the needed funding, the HeS011 (the intended engine for the He280) would have been ready by the time the He280 was production ready (at a time when the Me262 was still being developed).

Even still, proper funding for engine development may have seen the "bugs" worked out of the HeS08 engines that were installed in the He280 and carried the He280 aloft for trials and successful demonstrations.

So that oversight by the RLM early on, created a "what fortunately didn't happen" instead of a "what if".

Heinkel He 178 - Wikipedia, the free encyclopedia
It wasn't a combat aircraft, it was a proof of concept aircraft. The reason the RLM didn't run with it is there were better options at the time like the Me262 and the Jumo 004. The He178 was not a viable path to a combat model, while the He280 didn't have a viable engine; the Me262 and Jumo 004 were ready first.

You couldn't be further from the truth, honestly.

The He178 obviously was not a combat aircraft, (and I never said it was) even though in the following decades, jet design would adopt several innovations that the He178 possessed.

Now, the point being, that the He178 proved to the RLM that jet engines were a viable concept and not a "flash in the pan" like several other parallel technologies (like Caproni's ducted fan project), etc. and had the RLM fully backed the jet engine development in earnest in 1938/39, then the Hirth, Jumo and BMW engine development would have been far ahead of the game by the early 1940's. It wasn't until the war was well underway when the RLM suddenly realized their mistake.

So in a nutshell, the RLM looked at early jet technology much like the old school Admiralty looked upon steam engines fitted in ships, back in the day. It was different and they didn't like it.

And I am not sure where you got your information, but the Me262 was still on paper when the He178 was taking to the air. The He280 was much further along than the Me262 and was demonstrated to the RLM in April of 1941, while the Me262 prototype made it's first flight under piston power (Jumo210 mounted in the nose) a few days later (18 April 1941). It wouldn't be until 18 July 1942 that the Me262 flew under jet power for the first time.

The Jumo004 (and BMW003) was still on the bench, being developed in 1940, while the Hirth engine (HeS3, HeS8) had already been used to power the Heinkel aircraft.

Several jet engine issues had to be worked out before the RLM started funding jet engine projects in 1939 just before WW2 started; it was on the eve of WW2 that jet engines finally worked out several issues that finally made the RLM realize it was worth it. The He280 never got its engines working though:
Heinkel He 280 - Wikipedia, the free encyclopedia
Over the next year, progress was slow due to the ongoing engine problems. A second engine design, the HeS 30 was also undergoing development, both as an interesting engine in its own right, as well as a potential replacement for the HeS 8. In the meantime, alternative powerplants were considered, including the Argus As 014 pulsejet that famously powered the V-1 flying bomb.[4] (Using as many as eight was proposed.)[5]

By the end of 1943, however, the third prototype was fitted with refined versions of the HeS 8 engine and was ready for its next demonstration. On 22 December, a mock dogfight was staged for RLM officials in which the He 280 was matched against an Fw 190. Here, the jet demonstrated its vastly superior speed, completing four laps of an oval course before the Fw 190 could complete three.[citation needed] Finally, at this point the RLM became interested and placed an order for 20 pre-production test aircraft, to be followed by 300 production machines.

Engine problems continued to plague the project. In 1942, the RLM had ordered Heinkel to abandon the HeS 8 and HeS 30 to focus all development on a follow-on engine, the HeS 011, a much more advanced (and therefore problematic) design.[citation needed] Meanwhile, the first He 280 prototype had been re-equipped with pulsejets[5] and was towed aloft to test them. Bad weather caused the aircraft to ice up, however, and before the jets could be tested, pilot Helmut Schenk became the first person to put an ejection seat to use. The seat worked perfectly, but the aircraft was lost, and never found.

With the HeS 011 not expected for some time, Heinkel was forced to accept that it would have to use a competitor's engines, and selected the BMW 003. Unfortunately, this engine was also experiencing problems and delays, and in the meantime, the second He 280 prototype was re-engined with Junkers Jumo 004s while the next three airframes were earmarked for the BMW motor (which, in the end, would never be ready before the end of the He 280 project). The Jumo engines were much larger and heavier than the HeS 8 that the plane had been designed for, and while it flew well enough (for the first time on 16 March 1943), it was immediately obvious that this engine would be unsuitable in the long term.[citation needed] The aircraft was slower and generally less efficient than the Me 262.[2]
Less than two weeks later, on 27 March, Erhard Milch cancelled the project. The Jumo 004-powered Me 262 appeared to have most of the qualities of the He 280, but was better matched to its engine. Heinkel was ordered to abandon the He 280 and focus attention on bomber development and construction, something he remained bitter about until his death.

However, the fact remains, the He280 was presented to the RLM in full battle dress, demonstrated as a capable fighter aircraft, while the Me262 was still being developed. And the Jumo004 was too heavy for the He280, which was designed for the lighter Hirth engines.

So let's look back to 1938/39: the RLM yawned at the jet program. It didn't fully back and fund the program. So jet engine development was primarily left to the manufacturer. HAD the RLM fully backed and funded the programs (including exotic material aquisition), then the development would have moved forward instead of struggling along as it did historically.

The He280 was presented only in late 1943 when the Me262 was in the process of being introduced and would form its first demonstration unit within 6-7 month; even at that point the engines for the He280 were not production ready and were behind Jumo 004 development. In the 1938-39 period jet engines still had not demonstrated they were worth pursuing, as the He178 was largely a stunt and not militarily viable; when the development level finally demonstrated potential in 1939 Franz Anseln was tapped to start the Jumo 004 project with major funding:

I am really curious...where are you getting your information from?

First off, I think calling the He178 a "stunt" plane is a little bit ridiculous...it was a pioneer in the field of turbojet technology and was the world's first turbojet powered aircraft to achieve flight.

I don't see why you're so adamant to point out the He178 was not a military aircraft. It was never intended to be a combat aircraft. What it was intended for, was to prove the viability of jet powered flight and it did remarkably well, too. However, the RLM maintained the attitude that piston powered aircraft were adequate and jet development wasn't a priority.

Now, let's step away from Wiki for a moment and get down to some real information:
The He280 timeline is far ahead of the Me262.

18 April 1944 sees 13 pre-production (Me262A-0) units completed

And we'll end the statistics at this point.

So now, let's recap on this comment:
...The He280 was presented only in late 1943 when the Me262 was in the process of being introduced...

How is this possible when the first He280 airframe was being glide tested in 1940 at a time when the only Me262 in existence was made of plywood?

Also, if the Jumo 109-004 was given major funding, then why did development languish?
There was continuous meddling by the RLM, in particular, Hans Mauch of the the RLM's "Engine Development Bureau". The Helmut Schelp, who replaced Mauch, ordered several changes, which set back the engine developers yet again. And it was during this confusion that the RLM ordered Heinkel to abandon work on the HeS 30 (which was developing well and showed great promise) and instead, work on the HeS 011.

So let's look at the turbojet timeline here:
Heinkel
HeS 1 - first test: 1937
HeS 3 - first test: 1939 (first flight: 27 August 1939, He178)
HeS 6 - first test: 1939
HeS 8 (109-001) - first test: 1940 (first flight: 2 April 1941, He280)
HeS 30 (109-006) - first test: 1940
HeS 011 (109-011) - first test: 1943

Junkers Jumo 004 (109-004)
004A - first test: 1940
004A-0 - first flight: 18 July 1942, Me262 V3
004B - first test: 1943
004B-0 - first flight: 22 April 1943, Me262 V4

BMW BMW003 (109-003)
003A - first test: August 1940
003A - first flight: November 1941, Me262 V1
003C - first test: 1943
003E - first flight: 6 December 1944, He162 V1 (note: 003E was designation for mount modifications)

And even Porsche was in the process of developing a turbojet engine (109-005), but it was a little late in the game and not much came of it's development.

So we can still see a difference in your timeline and what really happened.

Hopefully, these figures might better help you understand the actual timeline of events!

The airframe was the easiest part of development. Its the engines that held up the whole project. The biggest part of the problem was the lack of nickel and several other metals that Germany did not have a major source for in wartime. So they couldn't get the Jumo 004A, which had no restrictions on metal usage and ready in 1942, into serial production, so had to go back and develop it again with steel parts and improved cooling so as not to melt the metals, which delayed introduction of the Jumo 004B until 1944, which also pushed back Me262 development. The HeS engines were never developed to take the steel parts that the Jumo and BMW did:
Heinkel HeS 8 - Wikipedia, the free encyclopedia
The HeS8 never solved its major issues and was much weaker in thrust than the BMW and Jumo engines, while requiring more rare metals.
Heinkel HeS 30 - Wikipedia, the free encyclopedia
Of all of the designs Müller brought with him, the HeS 30 was simplest and easiest to build. Müller had already built a test engine while still at Junkers, however it was only able to run at about half its designed RPM, which limited compression and required a continuous supply of external compressed air. The design was abandoned when Müller left, the Jumo team's simpler design being used instead. Müller promised Heinkel he could have the engine up and running on a testbed within one year of completing the move, a promise he was ultimately unable to keep.

Helmut Schelp, in charge of engine development at the RLM, refused to give Heinkel a production contract, an event Hans von Ohain claims brought Ernst Heinkel near tears. Schelp noted that while the design was excellent, BMW and Jumo were so far ahead they simply did not need another "Class I" engine – something that would prove ironic in another two years when both of those engines were still not operational. It also appears he had some misgivings about the compressor arrangement, but if this was the case it was never official. He also cancelled von Ohain's Heinkel HeS 8 at the same time.

There was nothing this engine could offer that wasn't already on the table and would need redesigns to conform to the lack of necessary metals heat resistant metals, which delayed both of the Jumo and BMW projects.

The HeS 30 had a better Power-to-weight ratio than the contemporary 003 or 004, it was more compact, it was less complex, required less exotic materials and had better fuel economy.

109-006: weight 860 pounds - max. thrust 1,896 lbf
109-003A: weight 1,375 pounds - max. thrust 1,760 lbf
109-004A: weight 1,805 pounds - max. thrust 1,980 lbf

So back to the original point: Had the 109-006 been allowed to develop (along with the rest of the jet engines in the various programs) then they would have been much further along in development and ultimately into production.

It might also be noted that the He280 was designed with the HeS 8 (and ultimately, the HeS 30) in mind...since these engines were lighter, more compact and required less fuel, the He280 was doomed when the ax fell on the HeS 30 development. It simply could not accept a different engine without drastically altering it's performance.

The Me262 even had to be altered from it's original design to accept changes in it's engine installation (hence the "swept" wings) to counter the change in CoG.
 
I know this thread is old but I find it very interesting. Especially the discussions of the armaments of the aircraft in question. I always thought the 50cal was a good weapon but not a great weapon. I've watched a lot of gun camera film of FW-190's and ME-109's shooting apart B-17's. Those 30mm's really tear apart a 17. I was surprised to read about the range of the 30mm's being so low. I assumed they'd carry further than a 50cal. I also have read a lot about the 20mm's being very effective. Was the 50cal really that superior to the other machine guns on fighters in WW2?
 
If by "machine guns" you mean guns with a bore under 14mm then it was in the top 3. If by "machine guns" you include guns with bores larger than 14mm (like 15-20mm ) then it falls (as all the 12.7-13.2mm guns do) a number of places.

The Russian 12.7mm and Japanese 13.2mm (Navy) guns were sort of a 3 way tie in effect on target with the US .50cal.
 
The 262's 30mm cannon would have been a major short coming against the F-80's .50 guns. Such low muzzle velocity would have seriously affected the range and hit probability. The F-80 would have swept the skies.

How many hits would you need from the .50" hmgs to get the same effect as one hit from the 30mm?

A hit with a .22 beats a miss with a .44, you have to hit first. The 30mm cannon was designed to take down bombers, the primary target for 262 pilots. A group of hits from a .50 cal, likely using high explosive or incendiary rounds, if not outright destroying the aircraft, will damage sub-systems, causing the stricken fighter to disengage.

If the Me 262 found itself with new jet fighters to oppose, I can not imagine it would have been difficult to fit some MG 151 or perhaps the new MG 213 to the airframe. The machine gun, 50 cal included, was obsolesent as a primary aircraft armament by 1944.
Perhaps a combination armament, like we saw with the MiG 15, would have been selected. 2 MG 213 and a single mk108 would have been devastating to bombers AND fighters
 
My bet would be on the ME-262. At the end of the war, it was already evolving. (larger more durable engines were in the works). The p-80 was still a test vehicle. By the time the P-80 would have been available, the ME-262 would be faster and further developed. The advantage to the ME-262 would be dive and run. Cleaner lines and heavier, and with the swept wings no compress-ability issues. Perfect for dive and zoom (P-40 warhawk against the Zero tactics) A better comparison would have been the P-59 which was at least ready for deployment before wars end. (that one would be a bad mismatch and fodder for the ME-262). The meteor also would be a poor match at least one on one.

Armament would be hard to compare. The .50 can spit out a stream of shells with good velocity which makes it better at deflection shots. The 30mm is just crazy destructive. (explosive energy vs kinetic energy) The estimate was two hits by the 30 mm to take down the average B-17. In a turning battle the 50 would be the better. In a dive and zoom, probably the 30mm.

Training and experience by the time the 262 was deployed was strongly leaning toward the US. Most of the experienced Luftwaffe pilots were dead, and the training program quality had badly fallen. The US on the other hand now had many experienced pilots, and excellent training. The Germans were working up tactics due to experience which could have shifted the bar a little at least in the initial encounters.

Are we talking about the skys over Europe in 1945? If so, being out numbered 50 to one would still leave the Me-262 out gunned and out maneuvered.
 
The specifications for the original P-80 was maximum speed 502 MPH. Only when improved engines were available in the late 1940's/early 1950's did the P-80 get to 558. You have to look at what the planes were like when the first P-80's were sent to Italy in 1945. The speed was essentially the same in level flight. The two were about equal speed wise, The P-80 better in the turn, the 262 better in dive and zoom. P-80 mechanicals all new and likely trouble probe as were the engines. Near equal specification wise, (P-80 a little out gunned) but also no experienced jet pilots on the P-80 side. Engine development was progressing rapidly on both sides, with the Germans a little ahead (we got their scientists after the war which made the advances in the P-80)
