The DoD plans to spend $27 billion acquiring launch services through the Evolved Expendable Launch Vehicle (EELV) program over the next 12 years. It uses 2 families of commercially owned and operated vehicles to launch satellites. The EELV program has undergone significant changes, including: adoption of a new acquisition strategy that sought to ensure the viability of the two EELV launch vehicle providers, Boeing and Lockheed Martin; the subsequent decision by those two co. to form a joint venture, the ULA; and a 10-year increase in the life of the program. This report: determines what uncertainties DoD faces in the EELV program and in the transition to ULA; and assesses how DoD is positioned to manage and oversee the effort. Illustrations.
