The head of Air Mobility Command (AMC) on Wednesday offered some new details about what went into repairing a KC-135 Stratotanker riddled with shrapnel holes from an Iranian attack. We have previously written about a couple of these jets damaged during Operation Epic Fury (OEF) as they came through RAF Mildenhall in the U.K. on their way back to the U.S. for comprehensive repair work. We are also getting new information of how AMC kept its fleet operating at such a prolonged high-tempo ahead of and during OEF.
The discussion about the damaged tanker took place during a panel at the Air & Space Forces’ Air, Space and Cyber Conference that TWZ is attending. The tanker in question was damaged as it was preparing for a mission, explained AMC commander Lt. Gen. Daniel H. Tulley.
“A KC-135 ops crew is in the jet,” he said. “KC-135 maintenance team is about to launch this jet. Unexpected Alarm Red [an attack warning]. Everyone jumps in a bunker.”
After the barrage, the airmen emerged from their bunkers and checked out the plane.
“That aircraft is smoking,” Tulley said. “There are holes in it, and it’s a fully loaded KC-135. Two hundred thousand pounds of jet fuel. Took 48 hours for that [fuel] to be drained out of that aircraft. In the meantime, first on the scene was I think the pro super [production superintendent] and the expediter. They immediately began to collect the fuel… They start to patch the holes. They start to fix all the systems. Long story short, they were eventually able to get that plane to make a transoceanic flight back home to be fully repaired.”
Tulley did not say where the attack took place. However, as we have previously reported, five tankers were reportedly damaged in an Iranian long-range strike on Prince Sultan Air Base (PSAB) in Saudi Arabia on March 14. That was later confirmed in a Department of War Inspector General report released earlier this week.
You can see two of the shrapnel-damaged KC-135s as they passed through the UK on the way home in the following photographs shared with us by aviation photographer Andrew McKelvey. We do not know if either of these is the one discussed by Tulley.
Lt. Gen. Linda Hurry, Commander of Air Force Materiel Command (AFMC), followed Tulley’s comments with additional details about the repair work.
“I’ll pick right up on that because it was our aircraft battle damage repair team that was actually able to patch their aircraft back together to get it back to Tinker [Air Force Base in Oklahoma] that can put it completely back where it needed to be,” she noted. Tinker is home to the Expeditionary Depot Maintenance (EDMX), which is “responsible for maintaining the Air Force’s sole source for Aircraft Battle Damage Repair (ABDR) rapid repair capabilities for the entire tanker and bomber fleets,” according to the Air Force.
“So with Operation Epic Fury, we’re asking those questions: What can we sustain for how long? And it begs a question about regeneration,” Tulley further explained. “You know, our new teammates have regeneration as part of their doctrine, so readiness in contact is the way we’re approaching this. What can we do to improve how we generate capability while under fire, in contact, persistently in an extended or protracted conflict? Lots of great examples of work being done to get after this. General Hurry’s team has brought a lot of capability forward at Mildenhall Air Base.”
One example of how this has worked has been repairing damaged aerial refueling booms in the U.K. instead of all the way back to the U.S., Tulley highlighted. The booms, which extend from the back of tankers so that receiving aircraft can get their gas, can be damaged by the process, especially during combat refueling.
“I think we turned 30 booms instead of bringing them all the way back to the states,” Tulley noted.
Repairing battle damage is certainly a unique situation for AMC airman, but keeping hundreds of the command’s tankers and cargo aircraft moving at such a high rate prior to and during the war was a huge undertaking that was helped by new maintenance concepts. The Air Force sent maintainers and parts to bases in Europe to drastically speed up major maintenance that would have demanded the aircraft return stateside.
“We moved some maintenance actions forward, so they didn’t have to – the aircraft didn’t have to go all the way back to the states,” Air Force Chief of Staff Gen. Kenneth S. Wilsbach said during his keynote speech earlier this week. “We put some of them in Europe, so they could get through some normal safety inspections that were either due or deferred. Got those done, and the aircraft doesn’t have to go all the way back to the states. They can go somewhere in Europe, get the thing done, and then get right back to the flight. And so, those measures by Air Mobility Command paid dividends in the readiness of our mobility fleet.”
Air Force Global Strike Command (AFGSC), which maintains the service’s fleet of strategic bombers and its ICBM force, did something similar at RAF Fairford in the U.K., AFGSC commander Gen. Stephen L. Davis explained.
“It’s a complex problem,” said Davis. “I would say in the past we probably didn’t do this the right way. When we thought a conflict was kicking off, the first thing we do is start sending bombers forward, and that actually consumes our readiness. So I think we got it right during OEF.”
“We pushed maintainers and support personnel forward to RAF Fairford, and then we actually took the bombers, we loaded them up in CONUS [Continental United States]. We took them to the Middle East. They actually did a mission. They employed, deployed, conducted a combat mission, and then landed at Fairford. And then for the next, well, I guess they’ve been there for now six-plus months.”
“They’ve been conducting nearly daily operations out of there,” Davis proffered. “When bombers are back at home base, they build readiness. When we deploy it forward, they consume readiness. And then, as [Gen. Hurry] said, we’re getting great support in terms of parts, in terms of supplies, and in terms of forward depot support. So that fleet remains healthy.”
Being able to do as much repair and maintenance work as close to the front lines as possible will be hugely important in any future fight against China, and, unfortunately, repairing battle damaged aircraft will be necessary too. Clearly, the Air Force has learned some very important lessons from Epic Fury.

The post How The Air Force Patched Up A Shrapnel-Damaged KC-135 appeared first on TWZ.
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.
“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.”
For the first time we have a Minister confirming the Boom is coming to Royal Air Force tankers, although the when and the how currently remain very much up in the air.

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.
One of the major advantages of the boom system is its higher fuel-transfer rate. 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.
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.
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:
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.
Another, more remote possibility could involve a podded boom arrangement, a concept that has been around for a while now, but which is gaining traction with the U.S. Air Force as it weighs options for future tanker capabilities.
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.
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.
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.
