Why Has the Cost of Navy Ships Risen. A Macroscopic Examination of the Trends in U.S. Naval Ship Costs Over the Past Several Decades

摘要

Over the past four decades, the growth of U.S. Navy ship costs has exceeded the rate of inflation. This cost escalation concerns many in the Navy and the government. The real growth in Navy ship costs means that ships are becoming more expensive and outstripping the Navy's ability to pay for them. Given current budget constraints, the Navy is unlikely to see an increase in its shipbuilding budget. Therefore, unless some way is found to get more out of a fixed shipbuilding budget, ship cost escalation means that the size of the Navy will inevitably shrink. In fact, by some estimates, even boosting the shipbuilding budget from $10 billion annually to $12 billion would only help the Navy achieve a fleet of 260 ships by the year 2035 rather than the nearly 290 it now has (CBO, 2005). To better understand the magnitude of ship cost escalation and its implications, the Office of the Chief of Naval Operations asked the RAND Corporation to explore several questions. These include the magnitude of cost escalation, how ship cost escalation compares with other areas of the economy and other weapon systems, the sources of cost escalation, and what might be done to reduce or minimize ship cost escalation.
