A KC-135 performs an aerial refueling demo with a F-15C Eagle during the 2022 California Capital Airshow. The KC-135R was the result of a modernization effort to re-engine KC-135As and some KC-135Es with CFM56 turbofan engines, 361 converted. The upgraded KC-135R can offload up to 50% more fuel, is 25% more fuel-efficient, is significantly quieter, and costs 25% less to operate than with the previous engines. Stratotankers have been in service since 1957 and will eventually be replaced by the Boeing 767-based KC-46 Pegasus.
