Open in interactive gallery →See aircraft like this on the live radar →

The Boeing KC-767 is an American twin-engine, wide-body aerial-refuelling tanker and transport aircraft, developed by Boeing as a military derivative of the 767-200ER airliner. It entered service in 2008 with the Italian Air Force and has been operated by Italy, Japan, and — briefly — Colombia, making it one of the principal medium-class Western tankers of the 2010s and the direct ancestor of the larger Boeing KC-46A Pegasus. Boeing pitched the KC-767 against the Airbus A330 MRTT for tanker procurements in the late 2000s and early 2010s. It lost the U.S. Air Force KC-X competition in 2008 to the Northrop Grumman / EADS A330 MRTT, but that selection was overturned, and the 2011 re-award went to Boeing's KC-46A — the lineal descendant of the KC-767.

The airframe is the 767-200ER: 159 ft (48.5 m) long with a 156 ft (47.6 m) wingspan. Empty weight is around 200,000 lb and maximum take-off weight is 395,000 lb. Two General Electric CF6-80C2 turbofans deliver about 62,500 lbf each, giving a maximum speed of Mach 0.85 (530 mph), a 40,000 ft service ceiling, 4,500 nmi range with maximum cargo, and 7,200 nmi as a tanker. The aircraft can carry 200,000 lb of transferable fuel together with 19 passengers and 19 standard cargo pallets. Distinguishing features include a rear-fuselage refuelling boom for USAF-style receivers, outboard wing-mounted hose-and-drogue pods for Navy and Marine Corps probe-equipped aircraft, a forward-fuselage cargo door, and a glass cockpit derived from the 767-300 / 777.

The KC-767's primary mission is medium-class aerial refuelling — supporting trans-theatre fighter and strike deployments, sustaining maritime-patrol aircraft, and combining tanker duties with passenger and cargo transport. It sits between the older KC-135 and KC-10 (which it can partly replace) and the larger A330 MRTT, which exceeds it in fuel offload and combined passenger / cargo / tanker payload. The wide-body, twin-aisle cabin gives it far better passenger and cargo capacity than the narrow-body KC-135, a key selling point for medium-class operators. The cockpit and avionics suite are drawn from the commercial 767 rather than the 1950s-era KC-135.

Italy fielded the type in 2008 and Japan in 2009. Italian Air Force KC-767As (4 in service) operate from Pratica di Mare AB outside Rome, supporting Italian fighter, transport, and maritime-patrol missions as well as NATO operations. The Japan Air Self-Defense Force flies 4 KC-767Js from Komaki AB in Aichi prefecture, refuelling F-15J, F-2, and E-767 AEW&C aircraft. The Colombian Air Force ordered 1 KC-767 in 2007 but cancelled before delivery; that airframe was sold to Brazil and converted for commercial passenger use. Total production reached 8 airframes (4 Italy + 4 Japan), built at Boeing's Everett, Washington facility, with the line closing in 2013. For new procurements, the type has been superseded by the KC-46A Pegasus, built on the closely related Boeing 767-2C airframe.

For Kids — a shorter, friendlier version

The Boeing KC-767 is an American tanker built from the 767 airliner. It first flew in 2005 and entered service in 2008 with the Italian Air Force. Only 8 KC-767s were built between 2008 and 2013. Italy, Japan, and briefly Colombia were the only operators.

The KC-767 has two GE CF6-80C2 turbofan engines, each making 62,500 pounds of thrust. Top speed is 530 mph, faster than most race cars. The plane is 159 feet long with a 156-foot wingspan, longer than a Boeing 737. It can carry 200,000 pounds of transferable fuel.

Like the KC-10, the KC-767 has a refueling boom on the back for Air Force jets. The wings have hose-and-drogue pods for Navy and other probe-equipped planes. The KC-767 can also carry 19 passengers and 19 cargo pallets at the same time as a refueling mission.

The KC-767 was Boeing's tanker pitch to the American Air Force in 2008. Boeing first lost the bid to the Airbus A330 MRTT but won a re-bid in 2011 with a bigger and newer plane called the KC-46A Pegasus. The KC-46A is the next-generation descendant of the KC-767, with a bigger fuel load and a refurbished cargo door.

Kids’ Questions

Why so few built?

The KC-767 came on the market when most countries already had old tankers from the 1960s. Replacing them was costly. Italy bought 4, Japan bought 4, and that was it. Boeing later offered an improved version called the KC-46A to win the much bigger Air Force order in 2011.

Why did Boeing lose the first bid?

In 2008, the Air Force first picked the Airbus A330 MRTT over Boeing's KC-767. The Air Force said the A330 was bigger and could carry more fuel. Boeing complained, and a review found problems with how the Air Force scored the bids. The contest was held again, and Boeing won in 2011 with the new KC-46A Pegasus.

How is the KC-46A different?

The KC-46A Pegasus is built from a newer 767 with stronger engines, more fuel, and better cameras for the boom operator. The KC-767 used direct visual sight for refueling; the KC-46A uses 3D cameras. The KC-46A also carries more cargo, troops, or medical patients than the KC-767.

Variants

KC-767A (Italian)
Italian Air Force variant. 4 delivered 2011-2013, operating from Pratica di Mare AB, Rome. Configured with refuelling boom plus wing-mounted hose-and-drogue pods and a combined cargo / passenger cabin. Used for Italian Air Force operations and NATO missions.
KC-767J (Japanese)
Japan Air Self-Defense Force variant. 4 delivered 2008-2010, operating from Komaki AB, Aichi prefecture. Differs from the Italian variant in being boom-only — JASDF receivers use boom-receptacle exclusively, with no probe-and-drogue requirement. Used for F-15J / F-2 refuelling and other JASDF missions.
KC-767C (Colombian, cancelled)
Colombian Air Force variant. 1 ordered in 2007, cancelled before delivery. The pre-built airframe was sold to Brazil and converted for commercial passenger service. Listed for context — it illustrates the limited export market for the KC-767.
KC-46A Pegasus (successor)
Direct successor based on the Boeing 767-2C airframe — close to the 767-200ER but with updated electrical, hydraulic, and structural systems. 109 delivered to the U.S. Air Force as of 2026, with 179 planned plus international orders (4 to Israel, 6 additional KC-46As to Japan). See the separate KC-46A entry.
Boeing 767-200ER (commercial base)
The commercial airliner from which the KC-767 derives. The 767-200ER (Extended Range) was a 1980s twin-engine wide-body, with around 250 built for commercial operators. Boeing began offering the military derivative in the late 1990s; both Italian and Japanese KC-767s are 767-200ER airframes converted to military configuration.

Notable Operators

Italian Air Force (Aeronautica Militare)
Primary operator. 4 KC-767As delivered 2011-2013, flown by 14° Stormo (14th Wing) at Pratica di Mare AB, Rome. Supports Italian fighter operations (F-2000A Eurofighter, F-35A), the Boeing P-72A maritime-patrol fleet, and NATO missions including Operation Unified Protector (Libya, 2011) and subsequent eastern-flank deployments.
Japan Air Self-Defense Force
4 KC-767Js delivered 2008-2010, flown by the 1st Airlift Wing (formerly 404th Squadron) at Komaki AB, Aichi prefecture. Supports F-15J, F-2, and E-767 AEW&C operations across the Pacific theatre. JASDF has since ordered 6 KC-46A Pegasus, with deliveries beginning in 2024 — the KC-767J and KC-46A will operate as a mixed fleet through 2030 and beyond.
Colombian Air Force (cancelled)
1 KC-767C ordered in 2007, cancelled before delivery for budgetary reasons. Listed for context — it shows how difficult it was to justify KC-767 procurement in smaller air arms, where the cost was not matched by mission demand.
Boeing test / development (former)
Boeing's flight-test fleet at Boeing Field, Seattle, operated 2-3 KC-767 prototypes for development work through 2010. Once Italian and Japanese deliveries were complete, the test fleet transitioned to KC-46A development. Design heritage from the KC-767 test programme fed directly into the KC-46A.

Frequently Asked Questions

How does the KC-767 differ from the KC-46A Pegasus?

The two are close cousins. The KC-46A is built on the Boeing 767-2C airframe — itself derived from the 767-200ER but with updated structural, electrical, and hydraulic systems. The KC-46A also introduces the Remote Vision System (RVS), which replaces the traditional boom-operator station with a video-based one, a 787-derived cockpit, and improved electronic-warfare protection. Both aircraft offer 200,000 lb of fuel offload and a similar cargo / passenger load; the KC-46A is best understood as a refresh of the KC-767 concept rather than a clean-sheet design.

Why didn't the KC-767 win the U.S. Air Force KC-X competition?

The competition ran in three stages with controversial outcomes. (1) The 2002-2004 lease-purchase deal between the U.S. Air Force and Boeing for KC-767As was cancelled in 2004 amid a corruption scandal involving Boeing CFO Michael Sears and USAF Acquisitions executive Darleen Druyun, both later prosecuted. (2) The 2008 KC-X competition was won by the Northrop Grumman / EADS proposal based on the Airbus A330 MRTT, but a GAO-sustained protest by Boeing on procurement-irregularity grounds overturned the result. (3) The 2011 re-competition went to Boeing's KC-46A — close in capability to the KC-767 but built on the updated 767-2C airframe. The KC-46A is the lineal descendant of the KC-767, drawing directly on Boeing's lessons learned during KC-767 development.

How many KC-767 were built?

8 airframes in total: 4 for the Italian Air Force and 4 for the Japan Air Self-Defense Force. A 9th, intended for Colombia, was pre-built but never delivered and was sold to Brazil for commercial use. Production at Boeing's Everett, Washington facility ended in 2013. The low volume reflects the narrow international market for medium-class tankers — most large air arms (USA, France, U.K., Australia, Canada, Saudi Arabia, India) chose either smaller (KC-135) or larger (A330 MRTT, KC-46A) types instead. The successor KC-46A has fared much better, with 109 delivered to the U.S. Air Force and 30+ to international customers.

What does the KC-767 cost?

Around $200-250M USD per airframe, depending on configuration and customer. The Italian Air Force programme — 4 airframes plus support equipment and training — totalled roughly $1.0-1.2B USD. The Japanese KC-767J programme (4 airframes plus support) came in at $800M-1.0B USD. The high per-airframe cost, comparable to the A330 MRTT, reflects the small production run, which prevented cost amortisation. The KC-46A has reached lower per-airframe pricing of $160-180M USD on the back of higher volumes.

Will the KC-767 be retired and replaced?

Italy and Japan plan to fly the KC-767 alongside the KC-46A in mixed fleets through 2035-2040. JASDF expects the KC-767J + KC-46A combination to remain in service through 2035; the Italian Air Force plans to keep the KC-767A flying past 2040. The fleet is still relatively young (delivered 2008-2013) and has plenty of structural life remaining. Any post-2040 replacement is likely to be a KC-46A derivative or a future Boeing tanker programme, but no formal successor programme is yet defined for either operator.

What aircraft can the KC-767 refuel?

It offers combined boom and drogue refuelling. The rear-fuselage boom services USAF-style receivers including the F-15, F-16, F-22, F-35A, F-2, F-15J, B-52, B-1, B-2, C-17 Globemaster III, C-5M Super Galaxy, RC-135 Rivet Joint, E-3 Sentry, E-7A Wedgetail, E-767 AEW&C, and P-8 Poseidon (boom-equipped). The wing-mounted hose-and-drogue pods — fitted to the Italian variant only, since the Japanese KC-767J is boom-only — refuel U.S. Navy and Marine Corps probe-and-drogue aircraft including the F/A-18E/F Super Hornet, EA-18G Growler, F-35B/C Lightning II, and AV-8B Harrier II. This dual refuelling fit matters for NATO operations, where USAF-style and Navy / Marine Corps-style receivers often need to be supported on the same mission.
