“Without tankers, America’s air power can’t get off the North American continent.” According to Dr. Andrew Latham, such was the statement used to highlight the importance of the Pegasus. The purpose of the tanker was to replace the KC-135 Stratotanker family that was already in the process of aging. However, due to numerous delays, problems, and design defects, the Air Force ended up dealing with a difficult situation, in which there has been a transition from the old platform to the new one, and many of the tasks associated with the latter are yet to be fully fulfilled.
As of late 2025, the service had accepted a total of 100 KC-46 aircraft, and in time, that number increased to 105. Nonetheless, acceptance did not mean that the aircraft ceased being a problem, since the entire fleet has been reported to have Category 1 deficiencies, which implies the worst class of operational shortcomings identified by the military.
The importance of the aircraft is dictated by the task the tanker is meant to fulfill namely, to provide long-range aerial refueling to bombers, fighters, and other receivers. Moreover, according to the design principles, the tanker was supposed to represent a next-generation aircraft, equipped with 787-derive cockpit and other state-of-the-art solutions. As such, the KC-46 is based on the 767 family but represents a significantly more advanced aircraft. However, the transition into the digital era was hampered by design flaws and software bugs.
The case is especially true in regard to the Remote Vision System (RVS). Since the aircraft does not feature any rear windows and is meant to conduct the refueling operations with cameras and displays, the RVS has been one of the defining features of the program that faced a great deal of issues associated with the quality of image and depth perception, requiring a complete overhaul. After several delays, the improved version of the system, also called RVS 2.0, is still in development.
Furthermore, the boom itself has failed to meet expectations in regard to light receivers, adding additional restrictions to the capabilities of the aircraft. Structural defects found during inspection in 2025 contributed even further to the problems associated with the KC-46 aircraft, thus confirming that there is something fundamentally wrong with the program. At the same time, the consequences of all the described issues are far-reaching, as the current generation of B-21 Raiders, together with the upcoming NGARef, require a highly efficient long-distance refueling solution.
As such, NGARef has moved from the stealth-tanker paradigm to survivability, connectivity, and self-protection, which is explained by the current context. Tankers are not expected to orbit within sanctuary anymore. Nonetheless, for the time being, the tanker that is capable of performing those roles does not yet exist, and the B-21s and NGARef need to rely on the KC-46 until their successors emerge.
At this point, it looks like the Air Force plans to continue purchasing the planes rather than launch a new recapitalization competition. Therefore, the current generation of the Stratotanker is bound to remain in use for some time. All in all, the tanker has become more than just a platform that was meant to replace the previous generation. It is the intermediary stage of transition from outdated to innovative concepts and technologies.
