The battle-repaired KC-135R Stratotanker photographed transiting through RAF Mildenhall has safely arrived at Tinker AFB, the hub for KC-135 depot level maintenance, but its future remains questionable.
As we reported previously, 59-1444, which currently sports a massive number of patch repairs across the airframe, was likely among the tankers damaged in the multiple Iranian attacks against Prince Sultan Air Base, Saudi Arabia, during March 2026. The attacks destroyed at least one E-3G Sentry, while at least five Stratotankers are reported to have been damaged. Damage to other types has been reported but not yet verified.
The aircraft landed at RAF Mildenhall, UK, on Apr. 12, 2026, with spotters at the fencelines immediately noticing the battle damage repairs (BDR) evident on the fuselage as well as on some of the engine cowlings. It had previously diverted into Chania International Airport, near Souda Bay, during its first attempt to fly from Prince Sultan to Mildenhall.
The squawk 7700 diversion to Souda Bay on Friday is a bit more interesting for KC-135R 59-1444 #AE0361. Seen arriving at RAF Mildenhall today, we can see repairs in patterns consistent w/ splinter damage from a high explosive detonation.

After departing Mildenhall on Apr. 13, the jet stopped over in Bangor, Maine, before completing its journey to Tinker Air Force Base, Oklahoma. Tinker is home to the Oklahoma City Air Logistics Complex, which oversees depot level maintenance for the KC-135 Stratotanker, KC-46 Pegasus, E-3 Sentry, E-6 Mercury, B-52 Stratofortress, and B-1B Lancer. With all of the facilities on site, Tinker was a natural destination for an airframe with such evident damage – and, as we mentioned previously, it would be ably equipped for any level of inspection, repair, and overhaul necessary for the aircraft.

The Aviationist now understands that, while full assessments have yet to take place, it is likely that 59-1444 will be withdrawn from service rather than repaired. Various undamaged components from the aircraft will be made available as spares to sustain the surviving fleet, which has been partially replenished following the fatal incident over Iraq as well as the Iranian strikes on Prince Sultan by bringing recently retired airframes out from the ‘boneyard’ (officially the 309th Aerospace Maintenance and Regeneration Group or AMARG) at Davis-Monthan AFB to Tinker for restoration to service.

Calling upon AMARG’s stock of retired aircraft for full refurbishment to operational standard is an uncommon but not unheard of practice, and has most notably been undertaken in recent years to maintain numbers of high value out of production airframes like the B-1B Lancer.
Tanker Pressures
The U.S. Air Force, when including airframes operated by various Air National Guard (ANG) units, currently has over 350 KC-135s in service. This compared to just shy of 100 KC-46 tankers. While far exceeding any other tanker fleet worldwide, the global operations of the U.S. military can still leave the tanker force stretched.
As we have seen during Operation Epic Fury, hundreds of tankers have been flying at an extraordinarily high tempo supporting not only direct combat operations but also transit flights and logistics taskings. Increased use of contracted aerial refueling services can alleviate a small amount of this burden, particularly for training sorties.
An Omega KDC-10 refueled a US Air Force B-52H and MC-130J over Pacific Ocean on Mar. 10, making it first commercial aircraft to refuel both aircraft. The KDC-10 transited from South Korea to Guam completing four successful contacts with B-52H and MC-130J.https://t.co/jRhPKM1zQS pic.twitter.com/11CrphdvBW

Meanwhile, the use and employment of the KC-135 – even after sixty years in service – continues to evolve. Earlier in April, as part of a Total Force Integration initiative, the Alaska Air National Guard’s 168th Wing took delivery of four additional Stratotankers. The Eilson AFB unit, nicknamed the ‘Guardians of the Last Frontier’, is the only U.S. aerial refueling unit based in the Arctic, and primarily supports F-16s and F-35s from Eilson alongside F-22s from Elmendorf AFB both on training and real world sorties.
Alaska’s proximity to Russia means that intelligence and defence probing missions from the Russian Air Force and Russian Navy are far from uncommon, and the significant over-water distances involved in many sorties reinforce the need for reliable tanker support. The U.S. Air Force’s press release states that the additional tankers “increases sortie generation, operational flexibility and the ability to sustain long-duration missions in austere environments”.
