| CA 15
An Australian griffon-powered mustang! Sound great! All I know is that it did 502mph! Any info at all would be greatly received!
I am also interested in the Rolls Royce Dart turboprop powered P51 how much better was it to the merlin powered versions? Also did the spitfire ever get tried with a Dart turboprop? |

Country:  | 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

Those stats sound similar to the Spitfire mk XIV's apart from service ceiling!

Country: | Yeah, it doesn't look quite right. Still she wouldn't of been a bad aircraft had she gone into service.

It was a completely new design that looked similar. The original plan was to have the CA-15 powered by a P&W R2800 radial engine which gave the a/c a completely different appearance. But, as I stated, these engines were not available so CAC went for the Griffon giving it it's "mustang" look. Quote: |

| Nothing. It was obviously too late to see any WWII service and was made obsolete by new jet a/c. It wasn't put into production because CAC (Commonwealth Aircraft Corporation) was already building Mustangs for the RAAF so the Govt. felt there was no need for this a/c.
