Israel has authorized the $3 billion purchase of a third squadron of F-35 stealth fighter aircraft, the Ministry of Defense announced on Sunday.

According to the ministry, the additional 25 Lockheed Martin (LMT.N) F-35s will increase the total number of F-35s in Israel’s air force to 75. The transaction will be paid for through the defense help Israel receives from the United States, the ministry added.

Israel was the first country outside the United States to acquire the F-35. In May 2018 its air force chief said that Israel was the first to use the plane in combat.

The F-35 is also known as the Joint Strike Fighter and in Israel by its Hebrew name “Adir” (Mighty).

Lockheed Martin and engine manufacturer Pratt & Whitney have agreed to involve Israeli defense companies in the production of aircraft components, the Israeli ministry added.
