Quick Answer: On May 4, 2026, a Boeing KC-46A Pegasus tanker built at Paine Field in Everett completed its maiden flight. Serial number 301, named Gideon, is the first of six ordered by Israel — and the first KC-46 ever delivered to an international customer. Delivery to the Israeli Air Force is expected early June 2026. Here’s the complete story of why it was built in Everett, why it matters historically, and what it means for the tanker workforce at Paine Field.
What Just Happened at Paine Field
Boeing’s KC-46 tanker program has logged a lot of firsts since its troubled early years. The first delivery to the U.S. Air Force. The first Remote Vision System fix. The first full-rate production approval. On May 4, 2026, it logged one more: the first KC-46 delivery to an international customer, built at Paine Field and flown from a U.S. military facility before its handoff to Israel.
The aircraft — serial number 301, assigned the Hebrew name Gideon after the biblical military leader — completed its maiden sortie on May 4. The Israeli Ministry of Defense confirmed the flight, noting the aircraft would be “equipped with Israeli systems and adapted to the operational requirements of the Israeli Air Force” before delivery. Specific Israeli modifications have not been detailed publicly, consistent with standard FMS security practice. Delivery is expected in early June 2026.
Why Israel Needs This Aircraft — And Why Everett Built It
Israel has operated aerial refueling tankers based on the Boeing 707 airframe since the 1970s. Those aircraft — heavily modified over decades by Israeli Aerospace Industries and Rafael Advanced Defense Systems — have supported some of the most demanding long-range strike operations in aviation history. The IAF’s ability to project airpower beyond Israel’s borders has depended substantially on what those tankers can carry and transfer.
The 707-based fleet is aging out. Airframes accumulated significant flight hours across 50 years of operational use. Parts are increasingly difficult to source. Modern threat environments demand more capable sensors, communications, and survivability features than 1970s architecture supports. The KC-46A Pegasus answers each of those limitations: fly-by-wire controls, modern avionics, a fuel offload capacity approximately 40% higher than the legacy tankers, compatibility with both boom-and-receptacle and probe-and-drogue refueling methods, and a design life intended to reach into the 2040s.
The connection to Everett comes from the KC-46’s airframe. The tanker is built on the 767-200ER commercial airframe — the same platform that anchors Boeing’s 767 freighter line at Paine Field, which is scheduled to run through 2027. Boeing builds both in the Everett complex: the commercial 767 freighters on one production floor, the KC-46 tankers on adjacent space in the same factory complex. When Gideon rolled off the line at Paine Field and flew its first flight, it was doing so on a production floor that Everett workers built and maintain.
The FMS Framework: How Israel Gets American Military Aircraft
Israel contracted for six KC-46As through the U.S. Foreign Military Sales program — the government-to-government channel that allows allied nations to acquire American defense equipment at U.S. procurement pricing. A 2022 Department of Defense contract covered the first four aircraft at approximately $930 million. In 2025, Israel expanded the order to six total aircraft.
Under FMS, Boeing contracts with the U.S. government rather than directly with Israel. The U.S. government manages the acquisition on Israel’s behalf, including delivery logistics, quality oversight, and coordination of any country-specific modifications. Israel pays the U.S. government; the U.S. government pays Boeing. This structure means the KC-46 order appears in Boeing’s U.S. government backlog rather than as a separate international line — but the aircraft are built at Paine Field and the work flows through Everett’s production floors the same way domestic Air Force aircraft do.
What Gideon Means for the KC-46 Program
The KC-46 program’s domestic story has been well-documented: approximately $8 billion in losses on the fixed-price Air Force contract, a multi-year Remote Vision System deficiency, and an Air Force that paused follow-on KC-46 procurement in early 2026 pending resolution of outstanding technical issues. That’s the program’s domestic chapter, and it remains unresolved.
Gideon represents the opening of the international chapter. Israel’s six-aircraft order is the first FMS KC-46 delivery. Japan has ordered 15 KC-46As. Italy has expressed formal interest. Each international customer adds production volume to the Paine Field tanker line, contributing to the workforce stability that Boeing workers on that floor depend on.
The timing matters in a specific way for Everett. The 767 commercial freighter line — which shares the same airframe as the KC-46 and the same production complex — is scheduled to wind down in 2027 as Boeing transitions to the 777-8F. The KC-46 tanker line is not winding down. International FMS deliveries extend the production runway for Paine Field’s tanker work, keeping skills and facilities active that the commercial 767 line would otherwise close with it.
The Everett Factory Context
Paine Field’s Boeing complex — formally the Everett Production Facility — is the largest building by volume in the world at approximately 472 million cubic feet. It currently houses the 777-9 final assembly line, the 767 freighter and KC-46 tanker lines, and is being configured for 777-8F production as that program ramps. The first production-standard 777-9 flew from Paine Field on May 7, 2026 — two days after Gideon’s maiden sortie — with Lufthansa’s full Allegris cabin already installed.
This is a production facility in active transition. The 767 commercial line is closing. The 777-9 is entering production deliveries. The 777-8F is being set up. The KC-46 tanker line — now proven out through the first international customer delivery — remains as one of the more stable elements of Paine Field’s production mix through the transition period.
Frequently Asked Questions
What is Israel’s KC-46 Gideon?
Serial 301, the first of six Israeli KC-46A Pegasus tankers. It completed its maiden flight May 4, 2026 and is due for delivery in early June. Built at Boeing’s Paine Field complex in Everett.
Is this the first international KC-46 delivery?
Yes. Israel’s Gideon is the first KC-46 delivered to an international customer under the Foreign Military Sales framework. Japan is next with 15 aircraft on order.
How many KC-46s did Israel order?
Six total. Four in a 2022 contract at ~$930M, expanded to six in 2025.
What does this mean for Boeing jobs in Everett?
International FMS deliveries add production volume to the Paine Field tanker line, contributing to workforce stability as the commercial 767 line winds down in 2027.
What is the KC-46 built on?
The Boeing 767-200ER airframe — same platform as the 767 commercial freighter, built in the same Paine Field complex.
