Service Life Extension Program
From Wikipedia, the free encyclopedia
The Service Life Extension Program (abbreviated SLEP), is a program developed in the 1980s to extend the useful designed service life of the US Navy's aircraft carriers. The concept subsequently expanded to all of the US Navy's life-extension programs for ships, aircraft, and combat systems. The original SLEP program was canceled in 1994, before John F. Kennedy could go through it; instead, JFK was put through an 18-month Comprehensive Overhaul program.
A similar program has been used for the US Air Force's systems, such as the F118-GE-101 SLEP program which updates the powerplant for the U-2 spy plane.
