Executive Summary
Recent experience and a number of key trends suggest two important conclusions with respect to the Navys carrier fleet. First, carriers are becoming increasingly vulnerable, a trend that cannot be easily (or cheaply) reversed. Second, there are a significant and likely growing number of alternatives to the carrier for providing prompt strike capabilities and conducting forward-presence operations.
These trends do not indicate that the Navy should consider abandoning the carrier. They do, however, suggest that the Navy should begin in earnest a transition process designed to reduce its reliance on the carrier to carry the overwhelming burden for strike and forward presence operations.
The United States Navy needs to accelerate its restructuring efforts toward developing a distributed capital ship. The distributed capital ship comprises a network of Navy long-range strike platforms, to include carriers, surface combatants and submarines armed with vertical launch systems capable of firing long-range precision-guided munitions (PGMs), such as the Tomahawk land-attack missile (TLAM). But it also would include new combatants, such as the arsenal ship and converted Trident submarines (so-called stealth battleships). This architecture of strike platforms would be integrated by an expanded version of the Navys Cooperative Engagement Capability.
There are several key trends that inform this observation:
- Carriers are likely to become increasingly vulnerable over the next decade or two, a trend that will not likely be easily (or cheaply) reversed. This growing vulnerability has both strategic and technological roots. The Navys growing emphasis on littoral warfare will see carriers operating less in the broad expanses of the worlds oceans and more along the shores of would-be hostile states. This will make carriers increasingly easy to find, while also reducing their warning time of an attack. Moreover, the diffusion of advanced targeting technologies (e.g., communications, positioning, and imaging satellites) and weapon technologies (e.g., submarines, anti-ship missiles, long-range strike systems such as ballistic missiles and high-performance aircraft, and even anti-ship mines), may increase substantially the carriers vulnerability.
- Since their spectacular performance in the Pacific Theater of Operations during World War II, carriers have, over time, seen many of their unique features eroded by technology. For example, the carriers displaced the battleship as the capital ship in large part because of its strike range advantage. But now that advantage has been eclipsed by other ships carrying long-range PGMs, and by long-range bombers. Whether it is the strikes on Baghdad during the Gulf War, or retaliatory strikes against Iraq after the war, or punitive strikes in Bosnia, increasingly the weapon of choice is the long-range PGM, not carrier-based aircraft. In short, there are a growing number of alternatives to the carrier for providing prompt strike capabilities.
- With the proliferation of ballistic and cruise missile technology, the long era of sanctuary for U.S. forward bases will probably come to an end. Third World nations armed with improved Scuds and low-observable cruise missiles will likely make the forward deployment of land-based aircraft and large ground forces in future regional conflicts a far more hazardous enterprise than it was during the wars in Korea, Vietnam, or the Persian Gulf. This will place a premium on the U.S. militarys ability to conduct long-range precision strikes against enemy weapons threatening in-theater, high-value, fixed-point targets. The primary means for conducting these strikes will be Air Force long-range bombers and Navy precision-strike platforms, linked into a distributed network.
The distributed capital ship offers the following advantages over current fleet strike capabilities:
- Military Effectiveness. The Navys strike capabilities are not likely to be sustained at even todays level of effectiveness unless the Navy can meet the challenge of increasingly capable Third World military systems. Much as the carriers of an earlier era held a range advantage in strike operations over the battleship, so today these latter-day battleships the arsenal ship and converted Trident submarine can outrange the carriers. They do so by virtue of their missiles and their reduced vulnerability, which will allow them to operate more closely to shore than do carriers at a comparable level of risk. The stealth battleships also can undertake offensive mining and countermine operations, and still operate with less detection and less protection in the littoral areas than can the carriers.
- A Hedge Against Uncertainty. An emphasis on a more balanced, more distributed fleet that exploits those technologies that are advancing most rapidly will provide future fleet commanders with a variety of options for conducting strike and presence operations. It also will present would-be adversaries with more operational problems to solve before they can feel comfortable taking on the U.S. Navy.
- Reduced Cost. The distributed capital ship offers the Navy a way out of its long-term budget dilemma. Maintaining a twelve-carrier force has crowded out investment in long-range precision munitions, countermine warfare, and the recapitalization of surface combatants, among other things. Carriers cost over $4 billion to construct and nearly $2 billion per year to operate. Projected costs for the arsenal ship run at about $700 million, and the conversion of Trident boats to stealth battleships is estimated at $450-700 million each. Due to dramatically reduced crewing, and the use of missiles in lieu of aircraft, among other factors, operating costs of a fleet employing a distributed capital ship approach is likely to be substantially lower than a fleet based principally on carriers. Finally, both the arsenal ship and (especially) the converted Tridents would require considerably less in the way of combat escorts, producing additional savings.
- Advantages Over Surface Combatants. Both the arsenal ship and Trident stealth battleship have three principal advantages over surface combatants. They are less vulnerable. With far smaller crews, their operating cost would likely be considerably less than those of surface combatants with comparable strike capabilities. Finally, the arsenal ship carries several times as many vertical launch systems (VLS) as any other surface combatant.
- Casualties (Strategic Culture). If the Navy is to make good on its avowed mission to be first on the scene in the event of crisis, and to provide a prompt global strike capability when the nation requires it, then it will have to find some way of doing it without putting so many of its sailors in harms way, especially for those contingencies where the stakes are relatively low. As recent crises have shown, the carriers have long since lost their monopoly in both crisis and strike operations to a variety of other platforms, from Marine amphibious ships, to Navy surface combatants, to long-range Air Force tactical and strategic aircraft. Over time, both the arsenal ship and the stealth battleship will likely offer an increasing capability to conduct substantial strike operations, while risking less damage to themselves and their crew, than the carriers.
In summary, it seems prudent for the U.S. Navy to begin the transition toward a distributed capital ship comprising perhaps eight to ten carriers (the number that can be sustained within projected Navy budgets), and between two and four arsenal ships and a comparable number of Trident stealth battleships. This should permit a vigorous level of experimentation and innovation to determine the optimal force that will comprise the distributed capital ship.
If the Navy fails to invest in a distributed capital ship strike architecture, and carriers do become progressively more vulnerable, the worst case scenario could be catastrophic. Under these circumstances, having bet everything that the future conflict environment at sea will be very similar to what it was during the Cold War, or the Gulf War, the Navy would be left with relatively little operational flexibility. Fortunately, the Navy leadership has wisely given itself the opportunity to create a fleet that will meet the very different geopolitical and military-technical challenges of a new era. But now it must seize upon that opportunity, for as Francis Bacon once observed, He who will not apply new remedies must expect new evils.
Introduction
For the U.S. Navy, the early months of 1942 proved a difficult and discouraging time. The devastating Japanese surprise attack on Pearl Harbor in December 1941 had destroyed or damaged much of the American Pacific Fleet sitting at anchor along Battleship Row. In the months that followed, as the Japanese scored one victory after another in the Philippines, Hong Kong, Singapore, and Wake Island the American people and their leaders were desperately searching for some sign, no matter how small, that the tide would soon turn and victory would ultimately be theirs.
To raise American spirits and signal national resolve to the enemy, President Franklin Roosevelt directed his military leaders to develop a plan for striking directly at Japan as soon as possible. Given the strategic situation, the great distances involved, and the forces and technology available, the Army and Navy found it necessary to combine their capabilities to meet the presidents demanding task. Sixteen modified B-25 Army Air Corps medium bombers received specialized training on short-field takeoffs to determine if they could operate off the decks of a Navy aircraft carrier. After determining the bombers could be launched from a 750-foot carrier deck, they were loaded aboard the carrier USS Hornet and, accompanied by a heavy escort, sailed for Japan. The "Doolittle Raid" was born.
The rest, as they say, is history. The Hornet sailed undetected to within 700 miles of the Japanese coast. Then, having been spotted by a Japanese fishing boat (part of a special early warning fleet of radio-equipped fishing boats), Lieutenant Colonel James Doolittle decided to launch his aircraft at maximum range, on rough seas and into a strong wind. All sixteen bombers made it to Tokyo, dropped their small payloads, and continued on to China where all but one crash-landed. Of the 80 crew members who lifted from the Hornet's pitching deck, 71 eventually returned to the United States.1
Although the Doolittle Raid did little to alter the course of the war, its impact on American morale was electrifying.2
Colonel Doolittle was awarded the Congressional Medal of Honor, and the nation received a much-needed psychological lift. Two months later, following the Battle of Midway, the tide of the war turned for good.
