Is the DO-335 a fighter?

 

[Laurelix]

Is the DO-335 a fighter?

Yes I'd say so

 

[Venomstick121]

I think the A-6 was but not the A-1 if I am correct

 

[Laurelix]

Im full aware that Tempest Mk II should also be on that list but I just can't seem to find the source for the exact SL performance.

F2G-2 Corsair ?
(per October 1944 ACP)
642 km/h at SL with capped pylons
655 km/h at SL without pylons

On the list now

P-63A-10 makes the list with 384mph (618km/h) at SL

 

[Laurelix]

No wonder the Americans didn't want the Germans to capture a P-63.

P-63A: 618km/h at SL
FW-190D-9 running with the utmost maximum settings, C3 Fuel and MW-50 literally needs all that do reach 620km/h at SL

Whilst at the same time the P-63A puts the turning capability of the FW-190D-9 to shame

 

[BarnOwlLover]

Though it didn't make World War II (P-51H barely did, though it didn't see combat), any such data on the XP-82/P-82B?

Is that a Bell Aircraft Corp Company chart? Yeah, Bell tended to ah, 'fudge' their test results.

It shows a performance level the USAAF test pilots certainly could not obtain at max power setting,
since in their official tests (WEP/75" Hg/ADI/1820hp), the P-63 only made "366.0mph" at "0 ft".

 

[J.A.W.]

Im full aware that Tempest Mk II should also be on that list but I just can't seem to find the source for the exact SL performance.

From the usual site, here it is: 416mph @ S-L.

(Caveat, it has the Centaurus running hard at +12lbs boost, on 150 grade avgas).

Do you have the exact source link?

Do you have the exact source link?

Same location as the graph you showed also appears: P-63 Performance Tests

DH Hornet Mk I : 387mph at S-L, on +20lbs boost.

Ok Hornet is on the list and P-63 is off the list

Added Spitfire Mk 21 with Griffon 61 engine and +18lbs/in boost

Based on Spitfire Mk.21 - PP.139
(2nd prototype of Mk 22)

375mph at SL
460mph at Optimal Altitude

Quick question….
Was the +21lbs/in boost for Griffon 61 also used during WW2?

Griffon 61 Spitfire with +21lbs/in boost would have 628km/h at SL

Edit: Yes, +21lbs boost was also used in WW2

Added Spitfire with +21lbs boost also to the list

But is that with post war 2800hp?

 

[Metrallaroja]

But is that with post war 2800hp?

No, check the link. 100/130 + water at 60''
Also btw F2G-1 655kph is at 100/130 Military Power at 52'' . So probably the fastest in power setting to speed.
