Operation Epic Fury will hit a month old by the weekend. It and the massive military build-up to it were made possible by a global logistics chain that only the Pentagon can supply. At the heart of it is the aerial refueling fleet. These aircraft have flown thousands of sorties to get materiel where it needs to be and fast. These have included stuffing the fuel tanks of C-17s with cargo holds full of Patriot missiles to dragging stealth fighters across the globe. Epic Fury has been one of many operations to heavily tax the tanker fleet in recent years. To get a much better insight into the tanker portion of the war and its impacts, we talked to one man with an extreme level of experience behind the controls of USAF tankers. For more than 20 years, Troy Pananon, a retired Air Force colonel, served in the aerial refueling community. He flew KC-10 Extender and KC-135 Stratotanker refueling jets and served as deputy commander of the 6th Air Mobility Wing at MacDill Air Force Base in Tampa, Florida (now 6th Air Refueling Wing), and later as commander of the 100th Air Refueling Wing at RAF Mildenhall in England.

Q: The Air Force tanker fleet has come under extremely heavy use in recent years, being widely utilized in the evacuation of Afghanistan, the massive deliveries to Ukraine, the constant crisis in the Middle East and the campaign against the Venezuelan dictator Nicolas Maduro. Now, the war in Iran. Talk about the strain this is putting on it, on the aircrews, the maintainers and the airframes, some of which rolled out during the Eisenhower era.

A: I would categorically say that there’s a huge strain on the entire ecosystem. The KC-135s were rolling off the assembly line in the 50s and 60s. Some of the technology, and we called it technology back then, was graduated from the Wright brothers technology. Parts on that aircraft are still reminiscent of some of the things that were invented by the Wright brothers. So it’s amazing to me that the KC-135 is able to operate, and it’s due in large part to the maintainers and the relentless effort that they follow through to keep those aircraft air worthy. If you think about the [airmen], how they’re operating in places you mentioned all over the world, they’re there. We’ve broken their normal routine. They’re away from home, away from their family and friends. So that’s a mental and physical stressor, because they’re in environments that they’re not accustomed to.

WHAT THE HELL DO YOU THINK BEING IN THE MILITARY IS!? A FUCKING PICNIC?

We don’t know how long this conflict could last. We’re approaching a high heat of summer in that region, and so depending on where some of these personnel are based or stationed, they’re certainly out of their normal circadian rhythm, their normal environmental routines. It is a huge strain on those maintainers and the airframes that we’re placing in different parts of the world, exposed to different elements than they may have been exposed to at their normal pace. Maintaining these aging aircraft is a strain on the entire ecosystem, and we are operating them at a high operations tempo, and surely that puts a lot of a significant strain on the KC-135. We do have the KC-46 that is helping to fill some of that void, but we just retired the KC-10, which was a tremendous workhorse. And so I would say that there’s a significant strain on the ecosystem.

Q: What are the biggest challenges in keeping these Cold War-era jets like the KC-135 flying? How difficult is it to find parts, and what do you do when you can’t?

A: That’s 100% accurate. There have been some breakthroughs in technology. I know that they’ve used 3D printing to help source some parts. They’ve even gone back to the boneyard and pulled parts off of older KC-135s. So resources will always be a great puzzle for our entire team to source. There’s no new assembly line. They shut that assembly line down back in the ’50s and ’60s. Some of the parts for those aircraft in general were from the ’60s, ’70s and ’80s. And then, you have to take those back and refurbish those certain parts. There’s not a lot of new technology that’s going on to these core platforms. The avionics, for sure, is newer. But everything that you add to this aircraft, I call it the Frankenstein effort – taking bolt-on technology to try and help modernize the fleet. And by modernizing that means that you’re also helping with the parts availability. But going back to the age of these aircraft, some of these parts were developed back in the ’40s and machined back in the ’50s and ’60s. Our teams have to get creative with the acquisition. And that’s a huge, huge challenge. But they currently have done a great job of putting new engines on the aircraft. And so that means that the parts availability is better in some cases, but it’s not a solution.

Q: What are some of the old parts you’re talking about that go back to the ’40s, or to the Wright brothers era?

A: Just think about the flight controls. If you, for whatever reason, need to replace certain pulleys or elements within the flight control system, those parts were thought-up and developed way back in the ’40s. Machined maybe back in the ’50s and ’60s. It’s still not a fly-by-wire aircraft like some of the modern aircraft that we have nowadays. And so you have to go back and machine some of these parts if they get wear and tear.

Q: The cause of the tanker crash is suspected to be a collision with another KC-135. How many close calls have you experienced in your career?

A: Well, I have a deep background in the KC-10, and that also gives gas and takes gas. So I’ve been within 10 feet of another aircraft, operating at close to 350 miles an hour. It’s an inherently dangerous occupation when you’re trying to receive fuel from another aircraft. I don’t think that was the case in this particular incident over Iraq. But at all times, everything we do is inherently dangerous because we operate within safe operating margins, but they’re tight. So, a simple split-second decision or maybe error puts you in a precarious position. But we have procedures that, if we make a mistake and we come close to another aircraft – there is a term that we use, which is ‘breakaway.’ And that tells both aircraft, ‘hey, we’re in a situation where we need to create some space between our aircraft,’ and we follow our procedures. It’s a safe maneuver, but probably makes the hair on the back of your neck stand up a little bit. I’ve been in this, I’ve been in situations where I’ve had to rapidly escape from another aircraft. But again, we get trained for this. We are highly trained. And I think because of the training, when a situation like that occurs, your instinct kicks in and you know what to do. And so, I don’t recall instances where two KC-135s had a midair collision, but certainly, we have had air-to-air collisions, just none in my recent memory.

Q: Give me a sense of how RAF Mildenhall and other bases in Europe and elsewhere keep these aircraft flying to generate sorties and deploy to combat zones like the Middle East.

A: The best part about having a forward operating base like Mildenhall is that you have all the resources in place, and in this particular case, they’re closer to where the conflict is. You don’t have as much of a long logistical chain, but you still have a logistics chain that you have to support. And so operating at a place like Mildenhall, a round the clock operation every day of the year, you do have weather to contend with on occasion, and you do have airspace constraints that you do have to contend with. But again, all of these crews are highly trained and so I would say that the operations tempo at a place like Mildenhall is extremely high. Just being able to have the support of the government there and the host nation that there is, and the local community is a big deal. I enjoyed my time there. Of course, we were there during COVID, during the global pandemic, and the lengths and support that we received from the host nation to ensure the safety of our community and our airmen was incredible.

Q: The 100th Air Refueling Wing has 15 tankers and more transit through. What are the concerns and checklists of objectives for a Mildenhall commander during a major contingency operation like Epic Fury?

A: It’s just our ability to support, right? You mentioned there are 15 tankers, but the airfield itself was able to surge to support twice as many. I currently don’t know how many aircraft that we’re currently supporting out of Mildenhall, but the ability to support that means that you have to be able to flex to the surge of the operation that you’re encountering. You have personnel that are helping to fuel the aircraft. You need personnel to maintain and sustain the aircraft. And so I would assume that we are getting support from bases in the United States. And they’re deployed there from all parts of our country and major units. The tanker fleet is a total force effort. Nearly half of the force resides in the [Air Reserve Component] ARC, and so personnel from Reserve, Guard, active duty, I’m sure, have been sent to help support operations like that.
