History of the Boeing KC-135 Stratotanker
The Boeing KC-135 Stratotanker was first introduced in 1956, with the first operational aircraft being delivered to the USAF in 1957. Designed to replace the KB-29 Superfortress and KB-50 Superfortress tankers, the KC-135 was built to meet the increasing demand for aerial refuelling during the Cold War era. With a range of over 4,000 miles and a payload capacity of 200,000 pounds, the KC-135 quickly became the go-to tanker for the USAF. Over the years, the aircraft has undergone numerous upgrades, including the installation of improved engines, avionics, and communication systems. Despite being surpassed by newer tankers like the KC-46 Pegasus, the KC-135 remains a vital part of the USAF's aerial refuelling fleet.Design and Capabilities of the Boeing KC-135 Stratotanker
