Although details remain sparse, Israel has announced that the long-touted F-35 has officially seen combat for the first time anywhere in the world.

Israel was not one of the original nine partner nations that helped to fund the F-35s development but is among the three foreign military sales (FMS) customers for the platform — and is now the first nation ever to use the F-35 in combat operations.

On Tuesday, Maj. Gen. Amikam Norkin, Commander of the Israeli Air Force, announced that the F-35, which was recently dubbed the “Panther” by test pilots, had already seen combat on at least two occasions, though he declined to specify which.

“The F-35 squadron has become an operational squadron. We are flying the F-35 all over the Middle East and have already attacked twice on two different fronts.” He said.
