Why the Indonesian air force wants the Su-35May 13, 2015 Rakesh Krishnan Simha, special to RBTH
The Indonesian air force has asked Jakarta to greenlight the purchase of advanced Russian Su-35 fighters. Here’s why it’s a sensible decision.

The Indonesian air force wants to replace its outdated American built F-5 fighters with the brand new Russian Su-35 Super Flanker, but the country’s political leadership is unable to act quickly because the U.S. is pitching in with its F-16 and F-18 jets.
Future proofingWith Australia planning to acquire 72 F-35 stealth fighters by the end of this decade, Indonesia needs to look at counter measures. Russia’s T-50 seems like the most ideal candidate but in the meantime the Su-35 can fill the interim and also take on the F-35 threat.
Dave Majumdar of the National Interest says a US Air Force official with experience on the F-35 believes the Su-35 could pose a serious challenge for the new American jet. The F-35 was built primarily as a strike fighter and does not have the sheer speed or altitude capability of the Su-35 or F-22. “The Su's ability to go high and fast is a big concern, including for F-35,” the Air Force official said.
According to Majumdar, “As an air-superiority fighter, its major advantages are its combination of high altitude capability and blistering speed—which allow the fighter to impart the maximum possible amount of launch energy to its arsenal of long-range air-to-air missiles.
“The Su-35 would be launching its weapons from high supersonic speeds around Mach 1.5 at altitudes greater than 45,000 ft; the F-35 would primarily be operating in the 30,000-ft range at speeds around Mach 0.9.”
Sergey Ptichkin of Rossiyskaya Gazeta says the Su-35S is almost identical to the Russian T-50 in terms of the on board electronics suite, control systems and armament. “Therefore it will not prove difficult for pilots to convert to the classic fifth generation fighter with its obligatory stealth technology: any pilot who has assimilated the Su-35S can easily convert to the T-50,” he says.
The upshot: Indonesian pilots will have had a head start when it comes to flying fifth generation stealth aircraft in the next decade.
