we're not really capable of making proper planes , but neither is israel , the f-35 is entirely built in the USA , if some israeli companies made minor contributions then that is a drawback for f-35I and not a positive point .
the only planes israel makes lavi and kfir don't look much more advanced than our own rebranded f-5s
Changes from standard F-35A[edit]
A senior Israeli air force official stated, "the aircraft will be designated F-35I, as there will be unique Israeli features installed in them."
The United States initially refused to allow the integration of Israel's own electronic warfare systems into the aircraft’s built-in electronic suite. However, Israel planned the introduction of a
plug-and-play feature added to the main computer to allow for the use of Israeli electronics in an add-on fashion, and to fit its own external jamming pod.
[54] The IAF dispatched two officers to the US where they discussed issues involving the integration of Israeli technology into the fighter with Pentagon and Lockheed Martin officials.
[34] In July 2011, it was reported that the U.S. had agreed to allow Israel to install its own electronic warfare systems and missiles in its F-35s in the future.
[55] In 2012 Lockheed was awarded a contract to make changes to the first Israeli F-35s to allow the installation of Israeli electronic warfare equipment produced by
Elbit Systems.
[56][57] This equipment will use "specific apertures... in the lower fuselage and leading edge".
[58] Israel also plans to install its own indigenously-produced guided bombs and air-to-air missiles in the F-35's internal weapon bays.
[54] Benni Cohen compared the Israel Aerospace Industries Command and control system to an iPhone App that would run on top of the central avionics.[59]
Israel Aerospace Industries will manufacture the outer wings of Israel's F-35s.
[57] IAI may also play a role in the development of a proposed two-seat F-35. An IAI executive stated, "There is a known demand for two seats not only from Israel but from other air forces. Advanced aircraft are usually two seats rather than single seats."
[60] The Israeli F-35s helmet-mounted displays will also be manufactured in Israel.
[61] This is part of the
Offset agreement provided to Israel, in spite of the purchase being entirely funded by American aid.
[62]
An IAF official stated that while the stealth of the F-35 in its current form will be overcome in 5–10 years, the aircraft will be in service for 30–40 years, and that is the reason that Israel insisted on the ability to make its own changes to the aircraft's electronic warfare systems.
[63]
The first 19 aircraft will be delivered as standard F-35As while the remaining 31 will be fully equipped F-35I.
