Well done Paul

No. 74 Sqn operated IXEs with rockets (they were the only Sqn. to do so), although MN477 did test the American M10 three tube cluster rockets, but they didn't get used in action by British forces.
A number of different extra fuel tanks were fitted to the IX including;
internal 75 gal. (in the rear of the cockpit)
45 gal. slipper tank
16.5 gal. wing tanks
BF274 was fitted with a Y-shaped bridle to enable her to be towed behind a Wellington, she was given a fully-featherable prop (the only one to have one) as the engine had to be kept idling or else it gummed up with oil.
Ozzy

Ps. Five IXs were the first Spits to be fitted with contra-rotating props as well

Fabulous plane
