The Republic of Singapore Air Force is one of the world's most modern air forces. It is also very large (100 combat planes) compared to the size of the country (276 square miles – less than a quarter of the area of Rhode Island). One could wonder how they fit all their planes in there?
The answer is, they don't. In fact, about a quarter of Singapore's primary combat jets, a total of 40 F-15SG Strike Eagles and 60 F-16C/D Fighting Falcons, aren't based in Singapore at all. They're in the United States.
You'll find ten of Singapore's F-15SGs at Mountain Home Air Force Base, the home of the 366th Fighter Wing (which operates F-15E Strike Eagles). They are assigned to the 428th Fighter Training Squadron.
Fourteen of Singapore's F-16C/D fighters are at Luke Air Force Base, the home of the 56th Fighter Wing, which handles training for not only the F-16, but for the F-35. They are assigned to the 425th Fighter Training Squadron.
So, why is roughly one-fourth of Singapore's combat aircraft inventory stationed across the Pacific Ocean, well over 8,500 miles away? Well, the answer is Singapore's small size, and its poor geography. Singapore is really an island nation pushed smack dab between Malaysia and Indonesia, and its airspace is less than six miles across.
One thing you need for flight training, though, is space, and a lot of it. This is especially true with high-performance fighters like the F-15SG and F-16C/D.
Transport helicopter pilots and basic flight training are done in Australia, where the trainees, it is safe to assume, can guzzle all the Foster's they want. Jet training for the Singaporean Air Force is done in France. Oh, and eight of Singapore's 17 AH-64D Apache Longbow helicopters are based near Tucson, Arizona.
In essence, Singaporean flight trainees get to see a lot of the world before they join a front-line unit. Not a bad way to enter service.
