The KC-46 Pegasus refueling tanker’s troubled remote vision system is now not expected to receive a replacement upgrade until summer 2027. This new timeline puts Boeing’s program over three years behind schedule, as confirmed by an Air Force spokesperson in an email on Wednesday.
The current projection for the fielding of the new system, referred to as RVS 2.0, is approximately two years away. However, the Air Force did not specify the reasons for the latest delay. Boeing has directed inquiries regarding the issue back to the Air Force. An Air Force spokesperson mentioned that both the Air Force and Boeing are exploring opportunities to prevent or mitigate this scheduling slip.
Older refueling tankers such as the KC-10 Extender and KC-135 Stratotanker require boom operators to visually guide the boom through a window in the back of the aircraft, often necessitating uncomfortable positions such as lying on their stomachs. The KC-46 was designed to improve this process significantly by allowing boom operators to use cameras and sensors from stations located towards the front of the tanker.
The original remote vision system developed by Collins for the KC-46 has faced numerous issues. Notably, it is criticized for its slow response to sunlight and shadows, as well as producing distorted images, which raises concerns about potential damage to receiving aircraft during refueling operations.
Boeing’s replacement, RVS 2.0, aims to resolve these issues by utilizing a combination of sensors, screens, and 4K ultrahigh-definition cameras to deliver a 3D, full-color image for the boom operators. Initially scheduled for release in March 2024, the timeline for RVS 2.0 has shifted multiple times due to supply chain issues and delays related to the Federal Aviation Administration’s airworthiness certification process.
Air Force Chief of Staff Gen. David Allvin reported to lawmakers that the KC-46 currently has five category 1 deficiencies, two of which are linked to its remote vision system. He anticipates an additional 18 months of development may be necessary for the RVS 2.0 to meet operational standards. According to Allvin, while the system is operational, it does not perform to expected levels.
Additionally, the KC-46’s stiff refueling boom remains a persistent issue, preventing it from refueling the A-10 Warthog and complicating testing with the future E-7 Wedgetail aircraft. Recently, Allvin and Air Mobility Command head Gen. Jon Lamontagne met with Boeing Defense leadership to discuss and analyze the major outstanding problems with the KC-46 in detail. Allvin summarized the situation by stating, “It is capable; it’s not optimal.”
