ABSTRACT
The Support Systems business unit of Boeing Integrated Defense Systems makes support equipment for military aircraft; the equipment is sold to all four major U.S. service branches (Army, Air Force, Navy, Marines) and to foreign militaries. Boeing Support Systems started in this market to support its own aircraft. Boeing Support Systems has since expanded and tries to compete for equipment that supports other military systems, as well. Boeing Support Systems makes and sells the support equipment, both
mechanical and electrical, to fit one of three different levels of maintenance: Organizational Level (O-Level), Intermediate Level (I-Level), and Depot Level (D-Level).
