The sale of F110 and F-35 aircraft to Turkey is facing obstacles, with some reports suggesting that Israel's intervention is a factor. However, the US has reportedly moved ahead with a $700 million sale of F110 engines to Turkey for its KAAN fighter jet program, despite concerns from lawmakers. The status of the F-35 sale to Turkey remains uncertain, with some indications that it may be hindered, while others suggest that Turkey is exploring ways to rejoin the F-35 program.
