Using a nsk-adjusted fuel index of 2.7, the leasing option will be significantly higher than the budget estimate in the next 30 years. The risk-adjusted cost baseline, lease adjusted for fuel uncertainty, and the budget baseline total obligational authority for FY97-FY37 is $8.608 billion, $9.560 billion, and $7.432 billion, respectively.

The JT3D re-engining program was expected to increase fuel delivery capacity of the KC-135Es by an average of 20 percent over that of the KC-135A and fuel efficiency by about 12 percent. Both the KC-135E and the KC-135R required a shorter takeoff distance at maximum gross weight than the KC-135A, enabling tankers to land at additional airfields.

Implications for the Guard and the Reserve Congress focused the JT3D re-engining program on the KC-135s in the Air National Guard and the Air Force Reserve. The Guard and Reserve, however, did not maintain backup aircraft in their inventory.
