I didn't think the R2800 was relevent as they didn't have any engines.

But it does prove that the CA-15 was not based or was not a modified -51, but an completely new design.

The CA15 was based on a Mustang (hence a similarity)

Wrong, It's a common misconception that it was based on a Mustang because of its similar looks. The CA-15 had a longer and bulkier fuselage and its operating weights were also greater. The need to install the inline Griffon instead of the R2800 necessitated the use of an under fuselage radiator which, coupled with the streamlined look of the Griffon, gave the CA-15 its "mustang" look.

Fair enough. I does make more sense this way because to fit a R2800 you would need a completely new design.

Oh, well when you are designing something new, you take something that works and then try to improve on it...

A great looking aircraft. Kinda has a 'comic book' look to it. Big and powerfull, probably short of grace though. Had we had them in service a bit earlier, probably still being too late for WWII service, they could have seen action in Korea. Who knows... maybe even a carrier variant could have evolved???

perhaps- all you'd need then is a carrier to put them on

Wildcat · Feb 4, 2007

C'mon Lanc we HAD carriers that served in Korea.

the lancaster kicks ass · Feb 4, 2007

as yes- the wonderfully named HMS Terrible before you bought her

abramsteve · Feb 6, 2007

Didnt the Sydney serve in Korea?

HealzDevo · Feb 6, 2007

Was it named HMS Terrible for the food quality on board? (Joking) Was that the HMAS Sydney's UK service name?

Yep the Sydney served in Korea with its air group of two Sea Fury Sqn's (805 808) and a sqn of Fireflies (817sqn).
The carrier HMAS Vengeance was also marked for Korean service but the war was over by this time and only made it to Japan.

Nah not because of the food mate, but because it was built in England!

Was it an Irish naming committee or a Scottish naming committee? (That is a joke based on the fact that the Irish and the Scotts aren't really that fond of the English...)

Design work on the CAC CA-15 first began in 1943 with the intention that the a/c was going to be powered by a Pratt and Whitney R-2800 radial engine, however it was announced that these engines would not be made available so CAC therefore decided on the Rolls Royce Griffon.
The CA-15 first flew in March 1946 and was handed over to the RAAF in June 46. It was damaged in a wheels up landing in Dec 46 and did not fly for a further 18 months. After this it was used in a very limited flying programme before being scrapped in 1950.
The 502mph was achieved in May 48 but only through a 4000ft dive, not in level flight. Although the Ca-15 resembles a Mustang it is infact a completely different design. It's unofficial name was the Kangaroo.
Some figures:-
Weights
Max overload 12 340lbs
normal loaded 10 764lbs
empty 7 540lbs

Armament
6x .50 machine guns in wings with 250 rounds each.
provision for 10 rocket projectiles
or 2x 1000lb bombs under wings.

Performance
Max speed at sea level 368mph
at 25 600ft 442mph
at 26 400ft 448mph
at 30 000ft 439mph
at 32 000ft 432mph

Initial climb 3 650ft/min
max climb 4 990ft/min
climb at 30 000ft 2 250ft/min
time to 20 000ft 5.5 minutes
service ceiling 39 000ft
range wing tanks only 1 150miles
max range + drop tanks 2 540miles

Where is the museum with this plane?, in USA??.

Sorry mate, no CA-15 exists anywhere in the world.

So they are an aviation link that is totally dead? What a pity still nice blueprints early on in the thread.

Unless somebody wants to spend big big money and make a replica.
