Indonesian Ministry of Defence revealed that it is renegotiating a cooperation program with the Republic of Korea to build 4.5 generation fighter aircraft. 

The countries signed a deal in January 2016 to jointly develop the fighter aircraft Korean Fighter Xperimental or Indonesia Fighter Xperimental (KFX/IFX). Under the agreement, Indonesia’s MoD will invest about US$1.3 billion in the Korean Fighter Experimental (KF-X) program. However, the country is now renegotiating the terms to make clear Indonesia’s gain from the program. Indonesia may not produce components although some of the components for the IFX could be produced locally, to facilitate a transfer of technology, chief spokesman of the Defence Ministry Brig.Gen Totok Sugiharto said.
