Israel received three F-35s from the US on Tuesday, bringing its total inventory of the revolutionary fighter up to five, but according to a French journalist citing French intelligence reports, Israeli F-35s have already carried out combat missions in Syria.

In Air Forces Monthly, Thomas Newdick summarized a report from Georges Malbrunot at the French newspaper Le Figaro that said Israel took its F-35s out on a combat mission one month after getting them from the US.

Malbrunot reported that on January 12, Israeli F-35s took out a Russian-made S-300 air defense system around Syrian President Bashar Assad’s palace in Damascus and a Russian-made Pantsir-S1 mobile surface-to-air missile system set for delivery to Hezbollah in Lebanon.

Israel has repeatedly and firmly asserted that its goal to make sure weapons cannot reach Hezbollah, a terror group that has sworn to seek the destruction of Israel.
