No. 2 OCU operates both single-seat F/A-18A Hornets and two-seat F/A-18Bs. The F/A-18B is largely identical to the A model aside from its dual cockpit, which reduces internal fuel capacity by about six per cent. Aircraft livery includes a yellow-and-black tail fin flash, the base featuring a yellow tiger's head outlined in black, with a red mouth, white fangs and white eyes. The unit crest shows a winged kangaroo carrying a joey in its pouch, symbolising "'Mother Australia' flying with her young". The motto is "Juventus Non Sine Pinnis" ("The Young Shall Have Wings").
