The six-nation exercise 'Pitch Black 2012' kicked off in Darwin, Australia on 27 July, with the Royal Australian Air Force hosting visiting aircraft and personnel from Indonesia, New Zealand, Singapore, Thailand and the USA.
Among the equipment on show are four of the Indonesian air force's great-looking Sukhoi Su-27 and Su-30 fighters, which are making a rare overseas appearance. We ran one picture of the formation arriving on our Image of the Day blog today (with two Boeing F/A-18As from the RAAF's 77 Sqn), but here are a couple more for your enjoyment (images courtesy of the Commonwealth of Australia).
The single-seat Su-27s deployed are aircraft TS-2703 and -2705, with the twin-seat Su-30s being TS-3004 and -3005, if you like to know that kind of thing. Indonesia flies five of each type.
