Transforming the Navy's Surface Combatant Force
The Bush Administration came into office announcing its intention to transform the military into a more effective and lethal force. Perhaps the most visible transformation effort involving the Navy is the drive to modernize the surface combatant force. That force, which represents more than one-third of the Navy's fleet, comprises cruisers, destroyers, and frigates. (It excludes aircraft carriers, amphibious ships, and support ships.) Over the next 10 to 15 years, the Navy plans to retire one class of destroyers, modernize its cruisers and frigates, and introduce three new classes of surface combatants. That plan--which is at the heart of the Navy's effort to expand the total fleet from a little over 300 ships to 375 ships--would produce a force of 160 surface combatants 25 years from now, compared with today's force of 115 surface combatants. The resources needed for that expansion, however, are much larger than what the Navy now spends on surface combatants. Thus, without large budget increases, transforming the surface combatant force could crowd out funding for other ship programs. The Congressional Budget Office (CBO) examined three alternative approaches
for structuring the surface combatant force that would limit average annual
spending on procurement and direct operation and support costs to roughly
the amount spent last year: $6.6 billion (in 2003 dollars). The Navy could
cap average spending at that level and still have a larger and more capable
force of surface combatants in 25 years. However, the additional money
that the Navy would spend under its plan would provide an even bigger and
more effective force than would any of CBO's options.
The Resource Implications of Modernizing the ForceAt present, the Navy's force of surface combatants comprises 17 Spruance class destroyers, 27 Ticonderoga class cruisers, 33 Oliver Hazard Perry class frigates, and 38 Arleigh Burke class destroyers. Although they continue to be adapted for other missions, those ships constitute the final Cold War generation of surface combatants designed for open-ocean naval warfare against the Soviet Union. The Navy proposes to introduce a new generation of surface combatants designed to confront new threats and perform new missions. With the demise of the Soviet fleet, Navy leaders have refocused their attention on influencing events on land and operating in crowded coastal regions. The Navy expects the next generation of ships, designed especially for coastal areas, to reduce the risks that U.S. naval forces might face in that operating environment (such as risks from mines, quiet diesel-electric submarines, and small, fast attack boats armed with antiship missiles) and to increase the ability of those forces to attack targets on land. The Navy's Modernization Plan
The DD(X) is intended to be a stealthy, multimission ship with an emphasis on land attack. It is expected to carry one or two 155-millimeter advanced gun systems capable of hitting targets up to 100 nautical miles away and as many as 128 vertical launch system cells for longer-range land-attack missiles. The Navy may buy up to 16 DD(X)s. The littoral combat ship is intended to be much smaller than the DD(X). The Navy wants it to be a "focused-mission" ship with a modular design, in which combat systems could be changed depending on what mission the ship was assigned to perform. At any given time, the LCS could be configured to carry out one of three missions: mine countermeasures, antiboat operations, or littoral antisubmarine warfare. The Navy has not stated officially how many littoral combat ships it plans to buy, but CBO assumed that the number is 56--consistent with statements by Navy officials and with briefings that CBO has received. The CG(X) would also be a multimission ship, emphasizing air and ballistic missile defense. Although the Navy has also not said how many of the new cruisers it intends to purchase, current Navy operating concepts imply a force of between 24 and 42 CG(X)s. CBO assumed that the Navy would buy 32 of the new cruisers through 2025. Under that transformation plan--which CBO refers to as the Navy's 160-ship plan--the envisioned inventory of 160 surface combatants would consist of 88 cruisers and destroyers capable of providing long-range air defense as well as 16 DD(X) destroyers and 56 littoral combat ships (see Figure 1). |
Budgetary Implications of the Navy's Plan
At the same time, other components of the Navy will need greater resources if Navy leaders are to achieve their overall force goal of 375 ships. CBO estimates that meeting that goal would require an average budget for ship construction of almost $17 billion a year between 2011 and 2020--or about $3 billion more than the average required for the 2003-2010 period and twice what the Navy spent between 1990 and 2002 (see Table 1). |
The Navy's ship construction budget has had a growing shortfall in recent years, and building a larger surface combatant force would exacerbate that problem. Before 2002, the Navy's total force goal for ships was officially about 300. (That goal was set in the 1997 Quadrennial Defense Review and appeared to be retained in the 2001 review.) Sustaining a 300-ship Navy indefinitely--that is, in steady state--would require spending about $11 billion a year on ship procurement, CBO estimates. But since 1990, the Navy has spent only about $8.5 billion per year, on average. Thus, the total shortfall in ship construction relative to the spending needed to maintain a steady-state fleet of around 300 ships now stands at almost $39 billion. (The shortfall relative to the 375-ship goal would be about $58 billion.) The bulk of that shortfall involves attack submarines. In the past year, senior Navy admirals have argued that they need 375 ships to perform all of the missions asked of the service. By far the biggest change in force goals is the increase in the desired number of surface combatants to 160. In short, the Navy is proposing a major expansion of the surface combatant force that will require considerable resources at the same time that other ship programs will need more funding if current force levels are to be maintained. Structuring the Future Force at Today's Funding LevelTransforming the surface combatant force need not be as expensive a proposition as the Navy's 160-ship plan would be. CBO examined three different options to structure the force, each of which would require no more than an average of about $6.6 billion a year (in 2003 dollars) for procurement and direct operation and support costs between 2003 and 2025. The three approaches emphasize different trade-offs between keeping the current generation of ships and transforming the force over the next two decades. Option I: Delay the Transition to Next-Generation Ships by Making the Most
of the Existing Fleet
Option II: Accelerate the Transition to Next-Generation Ships by Retiring
Much of the Existing Force Early
Option III: Buy Fewer Next-Generation Ships by Assigning Multiple Crews
to New Ship Classes
This option would also retire the Spruance class destroyers early and
upgrade all but the first five Ticonderoga class cruisers as well as the
Perry class frigates. It would buy eight DD(X)s and 28 littoral combat
ships. The CG(X) would be delayed until 2018, and only 15 would be purchased.
Those new classes of ships would use multiple crews and thus spend more
time at sea, so they would cost more to operate than single-crewed ships
would. Under this option, the surface combatant force would increase to
124 ships by 2025, but the multiple-crewing concept would make that force
equal to 165 single-crewed ships in peacetime (see Figure 1).
