The Israeli Air Force took a significant step toward modernizing its aerial refueling capability on May 4, 2026, as the Israeli Ministry of Defense confirmed the successful maiden flight of the nation’s first KC-46 Pegasus tanker in American skies. Designated 'Gideon' in Hebrew, the aircraft is scheduled to touch down in Israel in roughly one month after further testing and integration work.
This KC-46 represents the first of six tankers Israel has procured from Boeing through the U.S. Foreign Military Sales program. Officials emphasized that the aircraft will undergo substantial customization with domestically produced systems before entering frontline service. These modifications, which include advanced electronic warfare suites and other classified Israeli technology, mirror the extensive changes made to the country’s F-35 Lightning II jets that operate as the F-35I Adir variant. The adaptations are intended to allow the tanker to support extended-range missions while maintaining compatibility with the IAF’s unique operational doctrine.
The timing of the announcement is notable, arriving just one day after Israel’s Ministerial Committee on Procurement signed off on the acquisition of two additional fighter squadrons. One squadron will consist of F-35I stealth fighters — bringing Israel’s total F-35 fleet toward 75 to 100 aircraft — while the second will be equipped with Boeing F-15IA jets, an advanced derivative of the F-15EX. Recent contracts and approvals suggest each squadron will comprise approximately 25 aircraft, backed by comprehensive sustainment packages. The deals, valued in the tens of billions of shekels, form the opening phase of a broader 350-billion-NIS defense modernization blueprint approved at the highest levels of government.
For decades, the IAF has relied on a small fleet of converted Boeing 707 Re’em tankers for aerial refueling. These aircraft, some of which have been in service for nearly 60 years, are increasingly difficult to maintain and lack the modern capabilities required for high-tempo operations against distant targets. The six KC-46s will provide a one-for-one replacement while delivering markedly improved performance, including the ability to refuel multiple aircraft simultaneously using both boom and drogue systems. Industry observers note that the KC-46’s greater fuel offload capacity and enhanced survivability features will allow Israeli fighters to project power more effectively across the Middle East.
The KC-46 program with Israel has followed a deliberate timeline. The U.S. State Department first approved the potential sale of up to eight tankers in 2020. Israel formally committed to the type in 2021, leading to a $930 million contract award to Boeing in 2022 for the initial four examples with deliveries originally eyed for 2026. Subsequent requirements reviews resulted in two additional aircraft being added to the order. While infrastructure work to accommodate the new tankers at Israeli bases is already underway, the arrival of the first Gideon will mark the beginning of a multi-year transition period.
Boeing and Israeli industry partners have collaborated closely on the integration effort. The maiden flight itself included test points validating the aircraft’s core systems before Israeli-specific equipment is installed. Delivery and acceptance flights are expected to follow a compressed schedule to accelerate the tanker’s entry into service.
The developments reflect Israel’s ongoing focus on qualitative military superiority amid evolving regional threats. By pairing next-generation tankers with expanded fleets of advanced fighters, the IAF aims to maintain the ability to conduct long-range strikes while preserving air dominance. As the Gideon completes its final pre-delivery milestones in the United States, defense officials in both Jerusalem and Washington continue finalizing the larger fighter procurement packages that will define Israeli air power for the coming decades.
