Israel Finds Planes That Could Be Key to a Strike on Iran Badly Back-Ordered

WASHINGTON — Israel asked the Biden administration last week to speed up the delivery of refueling tankers that could prove critical to striking Iran’s nuclear facilities, but it was told that the aircraft were back-ordered and it was unlikely that its first one would be ready until late 2024, according to U.S. and Israeli officials.

The Israeli defense minister, Benny Gantz, made the request last week when he met with Defense Secretary Lloyd J. Austin III and other senior officials in Washington. Details were reported earlier by Yedioth Ahronoth, an Israeli newspaper.

While U.S. officials told Mr. Gantz that they would work to alleviate a production backlog, the timing of the delivery is a crucial issue: Biden administration officials are concerned that Prime Minister Naftali Bennett of Israel is trying to revive the threat of a military strike against Iran, after arguing that diplomacy has failed and that the country is closer than ever to a threshold capability of building a nuclear weapon.

The request came amid new tensions between Washington and Jerusalem over how to deal with Iran’s nuclear program. Since mid-2018, when President Donald J. Trump pulled out of a deal aimed at limiting Iran’s nuclear activities, Tehran has made significant gains in its nuclear fuel production, despite repeated operations by Israeli intelligence services to sabotage uranium-enrichment sites and a factory that produced nuclear centrifuges.
