Following the arrival of the RAF VIP Voyager “Vespina” at its base at RAF Brize Norton in Oxfordshire on Thursday 25th June 2021, the aircraft undertook its first operational tasking today Friday 26th June 2021, by tanking RAF Lightning and Typhoon fighters during Exercise CRIMSON OCEAN. After several weeks repainting, the Voyager was confirmed ready to undertake its full operational role of Air-to-Air Refuelling and personnel transport alongside the rest of the RAF Voyager fleet. Taking off from RAF Brize Norton, the aircraft spent most of the day airborne to provide several refuelling stops for the fighters taking part in the joint RAF and Royal Navy exercise. This refuelling occurred off the Northeast coast of the United Kingdom. Exercise CRIMSON OCEAN allows the Royal Navy and RAF to train and hone their ability to deliver routine fighter and helicopter operations in a range of environments from the aircraft carrier HMS Queen Elizabeth. Lightning aircraft from 617 Squadron have been onboard the carrier since 9 July when they left their base at RAF Marham in Norfolk. The aircraft, known as Vespina is also referred to as 'ZZ336', its military registration number, was previously visually indistinguishable from the rest of the RAF Voyager Fleet.

The paintwork concludes a refurbishment stemming from the 2015 SDSR.]() *Crown Copyright* The United Kingdom is moving toward adding a flying-boom aerial refueling capability to the Royal Air Force (RAF), a requirement being driven in large part by the future [Tempest]() combat jet, being developed under the [Global Combat Air Program]() (GCAP) initiative. In a [written response]() to opposition MP Ben Obese-Jecty, U.K. Defense Minister Luke Pollard confirmed that the RAF’s existing [probe-and-drogue aerial refueling]() capability will eventually be complemented by a boom system. The move would give Britain a sovereign capability to refuel aircraft equipped with the U.S.-standard boom receptacle, including the Tempest, while also improving interoperability with other NATO and allied air forces. ![This picture is from a Quick Reaction Alert training scenario. The QRA exercise was conducted 31 March 2026. The purpose of the exercise was to demonstrate the full end-to-end process of the UK's air defence strategy if an actual foreign aircraft was to invade their protected airspace. Upon receiving the alert, the QRA team at RAF Coningsby would launch to RAF Typhoon FGR4's to intercept any unknown aircraft within the protected airspace. In this particular scenario an RAF Voyager A330 (RAF Brize Norton) was acting as the agressor and two RAF Typhoons FRG4 (RAF Coningsby) were responding to the simulated threat. During the exercise the Typhoons intercepted the Voyager and conducted a series of maneouvers whilst communicating with the "foreign" aircraft with the aim of escorting it to a safe location on the ground (RAF Brize Norton) upon which it and it's crew would be guarded and safely inspected by counter-terrorist police. The resulting imagery is to be used for training government ministers on how a QRA works and all the different elements involved. From the initial radar detection of a foreign, unidentified aircraft at the London Area Control Centre, Swanwick, to the physical launch of our QRA team at RAF Coningsby. The RAF use a hose-and-drogue air-to-air refuelling system deployed from Voyager tanker aircraft. Instead of a rigid flying boom, the tanker trails a flexible high-pressure hose attached to a stabilizing basket (drogue), allowing receiver jets like the Typhoon and F-35 to plug in mid-flight. This image shows a Typhoon releasing flares as a warning to the "enemy aircraft".]() *A Royal Air Force Typhoon FGR4 accompanies a Voyager tanker during a Quick Reaction Alert training scenario in March 2026. *Crown Copyright* Crown Copyright* “The Royal Air Force currently operates a probe and drogue air-to-air refueling system and will complement this with the development of a boom system,” Pollard said. “This will ensure we have a sovereign air-to-air refueling capability for the future Royal Air Force fleet that enhances interoperability with NATO allies and partners.” ![]() https://twitter.com/Gabriel64869839/status/2095268510788157857?s=20 The decision follows comments by a senior RAF official in July indicating that the service was already examining how to meet the requirement. “We currently do not have boom \[-equipped tankers\] in the UK. We have a requirement for a boom from GCAP, so we have to resolve that requirement and that is what we are now looking at,” the official said at the Air Power Association Global Air and Space Chiefs’ Conference in London, [according to *Janes*](). “I \[am\] certain that at some point we are going to have to work out how we deliver a sovereign boom capability for our own combat aircraft.” The requirement is particularly significant because GCAP’s Tempest is being designed with a fuselage-mounted receptacle for boom refueling. Unlike the probe-and-drogue arrangement used by the RAF’s existing [Voyager]() tankers, a flying boom uses a rigid, telescoping refueling tube that is maneuvered by an operator aboard the tanker into the receiver aircraft’s receptacle. ![230220-N-NO777-1002 ROMANIA (Feb. 20, 2023) A Royal Air Force A330 tanker performs aerial refueling of a Spanish Navy AV-8B Harrier during combined long range strike training, Feb. 20, 2023.

That makes it especially useful for large aircraft and combat aircraft that need to take on substantial quantities of fuel quickly, reducing the time spent on the tanker. Tempest is not, however, the only RAF aircraft that depends on the boom standard. The RAF already operates several boom-equipped receiver aircraft, including [P-8A Poseidon]() maritime patrol aircraft, [RC-135W Rivet Joint]() intelligence, surveillance, and reconnaissance aircraft, and [C-17A Globemaster III]() airlifters. The [E-7A Wedgetail]() airborne early warning aircraft also uses a boom receptacle, while the forthcoming RAF [F-35A]() fleet will add another major boom receiver to the service. ![The first Wedgetail Airborne Early Warning (AEW) aircraft, destined to serve with the RAF, has arrived at RAF Lossiemouth on 21 May 2026. The aircraft was flown to RAF Lossiemouth by a mixed crew of personnel from Boeing UK and the RAF from STS Aviation Services at Birmingham Airport. The Wedgetail AEW Mk1 is the RAF’s next-generation airborne early warning and control aircraft, designed to deliver long-range surveillance, battle management, and command and control for air and joint operations.]() *The first Wedgetail aircraft, destined to serve with the RAF, at RAF Lossiemouth, Scotland, in May 2026. *Crown Copyright** Currently, the RAF has no boom-equipped tanker to support them. Its principal tanker fleet consists of [Airbus A330 Multi-Role Tanker Transport]() (MRTT) Voyager aircraft operated by the AirTanker consortium and leased to the RAF under a private finance initiative. Unlike many A330 MRTT operators around the world, which acquired the aircraft with a flying boom, the British Voyagers were configured exclusively around hose-and-drogue refueling. The Voyager K2 is equipped with two wing-mounted Cobham 905E hose-and-drogue refueling units. The K3 adds a third refueling point in the form of a Cobham 805E fuselage refueling unit, or FRU, located at the rear of the aircraft. The latter provides a higher fuel-transfer rate than the wing-mounted units. ![]() *The view from the cockpit of an A400M during air-to-air refueling with a Voyager KC3, via the fuselage refueling unit. *Crown Copyright** Since the fuel is stored in existing tanks, the Voyager’s cabin is still available to accommodate up to 291 passengers and the cargo hold for freight. One Voyager, serial ZZ336, nicknamed *Vespina*, is [modified for long-range VIP transport]() but still functions as a fully capable tanker. ***A video showing Voyager ZZ336 refueling RAF and German Eurofighter Typhoons during the enhanced Air Policing mission in Romania:*** https://www.youtube.com/watch?v=FNTSwZ45g9c Up to 14 Voyagers are available to the RAF under the current arrangement. The future of those aircraft is now one of the key questions surrounding Britain’s planned boom capability. One possibility would be to modify some of the existing Voyagers, installing a boom system in the rear fuselage. The baseline Airbus’ A330 MRTT design already incorporates a provision for a flying boom. At the time the United Kingdom ordered its Voyagers, boom refueling was not considered essential, so the capability was deleted to save weight, complexity, and cost — a decision which was to prove very shortsighted. Such a conversion, however, would involve engineering, certification, ownership, and contractual considerations, particularly given that the RAF does not directly own the Voyager fleet. Britain could also decide that modifying the existing aircraft is not worthwhile. The current Voyager private-finance arrangement runs until 2035, by which point the airframes will be considerably older. Rather than investing heavily in aircraft approaching the end of their contracted service period, the government could opt to acquire new A330 MRTTs or another tanker type equipped with a boom from the outset. ![A Republic of Singapore Air Force A330 Multi Role Tanker Transport leads a formation flight during a training scenario alongside a U.S. Air Force F-16C assigned to the 36th Fighter Squadron, Osan Air Base, Republic of Korea, two RSAF F-15SGs, and a Royal Thai Air Force F-16ADF during Exercise Cope Tiger 23, Korat Royal Thai Air Base, Kingdom of Thailand, March 22, 2023.

It remains unclear, however, whether a podded boom would offer the performance and integration characteristics required for Tempest and the RAF’s wider fleet. There is also a question about what platform it could be installed on. ![As part of its seemingly never-ending search for new fighters, the Indian Ministry of Defense says it wants to team up with one of the two rival European next-generation combat aircraft programs.]() *A rendering of the Tempest future combat jet. *BAE Systems* BAE Systems* At the same time, *TWZ* [has previously highlighted]() how drones equipped with buddy stores could operate in a hub-and-spoke model, ferrying fuel from tankers positioned outside the threat envelope to aircraft operating at the tactical edge. This could be another option that might gain traction as the U.K. Ministry of Defense increasingly looks to unlock the potential of [uncrewed capabilities](), but must also be considered less likely, especially as a primary solution. There is also a potential requirement for the tankers themselves to be capable of receiving fuel. Equipping a tanker with a receiver system would allow tanker-to-tanker refueling, extending the flexibility and reach of the RAF’s future air-to-air refueling force during long-range operations. Other A330 MRTT operators already benefit from this feature. ![A Republic of Singapore Air Force Airbus A330 Multi-Role Tanker Transport (MRTT) refuels a Royal Australian Air Force KC-30A MRTT during a 'Boom Camp' in the Northern Territory \*\*\* Local Caption \*\*\* Combined training was conducted by air-to-air refuelling tanker crews from the Republic of Singapore Air Force (RSAF) and Royal Australian Air Force (RAAF) at RAAF Base Darwin over 25 to 30 October 2020. Both nations operate variants of the Airbus A330 Multi-Role Tanker Transport (MRTT), which in RAAF service is called the KC-30A, and can carry a fuel load in excess of 100 tonnes that can be transferred in-flight to compatible receiver aircraft. The combined training at RAAF Base Darwin was an opportunity to compare experiences operating the MRTT and build working-level relationships, forging closer ties between RSAF’s No. 112 Squadron and the RAAF’s No. 33 Squadron. The RAAF was the world’s first MRTT operator, introducing the aircraft to service in 2011. The RSAF received its first MRTT in 2018 but has extensive experience with conducting air-to-air refuelling with the previous KC-135 Stratotanker, which had previously been used in support of RAAF exercises and training activity. read less]() *A Republic of Singapore Air Force Airbus A330 MRTT refuels a Royal Australian Air Force KC-30A MRTT during combined training at RAAF Base Darwin in Australia. *Australian Department of Defense* Republic of Singapore Air Force* While Tempest is providing the immediate catalyst, a refueling boom capability would also close an increasingly conspicuous gap in the RAF’s tanker force. The service is acquiring and operating an increasing number of aircraft built around the boom standard while relying on a tanker fleet configured around the alternative hose-and-drogue system. Whether Britain modifies its existing Voyagers, replaces them, or adopts another solution entirely could become an important part of the RAF’s long-term force structure as the Tempest program advances. *Contact the author: thomas@thewarzone.com* ## Author Thomas Newdick is a staff writer at *TWZ*, where he covers military aviation, defense technology, weapons systems, and international security.
