The source said that the delivery was postponed due to technical reasons but Russia would meet the earlier announced deadline and the last contracted Su-27SKM plane will be delivered to the same base on September 16.
Under a $300 million contract, signed in 2007, Russia is to complete the delivery of three Su-30MK2 and three Su-27SKM fighters to Jakarta by the end of 2010 in addition to two Su-27SK and two Su-30MK fighters purchased in 2003.
On the whole, Russia sends the planes to Indonesia earlier than scheduled following a request by the Indonesian military authorities, who would like the aircraft to take part in a military parade dedicated to Armed Forces Day on October 5.
Indonesia earlier said it needed at least one squadron equipped with 16 Sukhoi fighters to replace part of the outdated fleet of U.S. F-16 fighters.
