Additional details of the new 4.5 generation combat aircraft being developed by South Korea with Indonesian participation have emerged at Indo Defence 2018.
The KF-X/IF-X programme is being managed through a Joint Programme Management Organisation, based in Incheon Korea, that brings together South Korea’s Defence Acquisition Program Administration (DAPA) and the Indonesian MOD. The 4.5 generation fighter will feature advanced avionics, AESA radar and advanced sensors, smart weapons, enhanced survivability and high energy maneuverability.
Indonesia’s state owned airframer PT Dirgantara Indonesia (PTDI) is tasked with delivering a modified Indonesian version of the Korean KF-X, 4.5 generation stealth multi-role fighter, which is being developed by Korea Aerospace Industries (KAI). TNI-AU specific requirements call for the IF-X to be fitted with a drag chute, external 480-gallon fuel tank and new weapons and sensors.
As per the KF-X/IF-X final configuration (C-109). The single seat and twin seat aircraft will have a wing area of 46.5 sq mt and max thrust of 41,392 Ib, using two GE F414 engines. While Maximum Takeoff Gross Weight (MTOGW) has been stated for both types as 25,211 kg; empty weight for the single seat variant is 11,696 kg, while the twin-seat aircraft will weigh 12,048 kg. Max payload for both variants has been pegged at 7,257 kg. In terms of fuel capacity, the single seat aircraft can carry 5,262 kg as compared to 4,237 kg for thee twin-seater.
In addition, flight training and maintenance training systems comprised of simulators, cockpit procedure training systems, maintenance training devices and computer-based training tools will be developed. It is expected that Indonesia will also play a major role in the development of these systems as also other avionics equipment.
KAI is the prime contractor for the programme and will coordinate with Lockheed Martin, Domestic and foreign suppliers, Indonesia’s PTDI and industry and academia. DAPA is handling the development of the AESA radar for the KF-X programme. There will be six flight test prototype aircraft and two structural test prototypes built over the course of developmental testing.
A model of the KF-X at the KAI stand shows the aircraft carrying two air-to-air missiles (AAMs), two precision guided munitions (PGMs), a laser designator pod, recce pod and two drop tanks.
