The Boeing KC-46 Pegasus, a military aerial refueling and strategic transport jet, is derived from the Boeing 767 airliner. Initially developed to replace older Boeing KC-135 Stratotankers for the United States Air Force (USAF), the first delivery occurred in January 2019. The USAF plans to acquire 179 units by 2027.
Determining the cost of a KC-46 Pegasus involves two main expenses: purchase price and operational costs. The aircraft's exact purchase price is not publicly available due to its custom-built nature for military clients. However, a recent $2.4 billion agreement between the USAF and Boeing for 15 additional tankers suggests an approximate cost of $159 million per unit.
Boeing reports that the global fleet has logged over 100,000 flight hours and offloaded more than 200 million pounds of fuel. Despite some technical challenges resulting in $7 billion in losses, these new orders are significant for the program.
