Two F-35 fighter jets, known in Hebrew as "Adir" jets, landed at Nevatim Airbase in southern Israel on Sunday, the IDF said. The jets join the two squadrons the military declared operational in December 2017.
"The ongoing procurement of the Adir is another expression of the long-term military cooperation between Israel and the US, which continues to produce exceptional results in the process of strengthening and streamlining [the F-35]," the IDF said in its statement.

The Israeli Air Force is the first air force in the world outside the US with an operational F-35 squadron.
"The capabilities of the Adir Squadron add another tier to the operational and strategic capabilities of the air force, which ensures the air force's superiority in all its missions, namely the protection and safety of the State of Israel's skies," the IDF said in a statement.
Last week, Prime Minister Benjamin Netanyahu warned Tehran that Israel's F-35 fighter jets can reach "anywhere in the Middle East," following threats against Israel in recent weeks by senior Iranian officials.
Israel has agreed to purchase at least 50 F-35 fighter jets from the US defense contractor Lockheed Martin. They will be delivered in batches of twos and threes until 2024.
Last month, the IAF held a large multi-day exercise simulating combat action on multiple fronts, with F-35s taking part for the first time.
