The July 7-8 summit, which is being hosted by President Recep Tayyip Erdogan, will bring together leaders from the military alliance's 32 member states. In June, Trump promised to make Erdogan "very happy" when asked about Turkey looking to secure F110 jet engines and being readmitted to the F-35 fighter jet programme. Analysts said it would likely mean freeing up fighter jet engines Turkey wants to use in its flagship KAAN stealth fighter project. "It's likely to be the green light for the F110 GE engines for the KAAN fighter plane, about 40 of them. There had been obstacles to that supply and very possibly those are now being removed," Sinan Ulgen, director of the Istanbul-based Edam think tank, told AFP. "Turkey has produced a couple of prototypes which are flying with the F110 engine, but it has been waiting for the supply of additional engines to increase the number of KAAN platforms," he said. KAAN is a twin-engine stealth fighter being developed by Turkish Aerospace Industries (TAI) to replace the Turkish Air Force's fleet of F-16s as Ankara seeks to join the exclusive club of nations producing fifth-generation combat aircraft, notably the US, China and Russia. Although Turkey will eventually fit the fighter with its own domestically-produced engine -- the F110s lacking stealth capability -- that project is still in the preliminary design phase, Defence Minister Yasar Guler said in September. Turkey received a first batch of 10 F110s in September, and talks with the US government to acquire 80 more were "ongoing", he said. (Bssnews)
