Greg Easterbrook’s recent column “Our Navy is Big Enough” in the New York Times demonstrates that one lecture at the Naval War College does not a naval expert make. Easterbrook advances two arguments. First that the Navy, at 275 ships, is large enough to meet all of the nation’s naval maritime security needs. Secondly he states that the Navy’s proposed budget proposed budget of $161 billion is far in excess of spending requirements. That he would correlate the size of the Navy’s budget with the size of the force deployed demonstrates his shallow awareness of matters maritime. In both the case of the size of the fleet and the size of the budget, it all comes down to math.
The size of the fleet is measured largely against two separate standards. The first is the size of the force necessary to fight and win the nation’s wars. This standard often looks first to the capabilities a potential challenger might field and then estimates the size of the US naval force required to ensure US victory. Such analysis attempts to present the capabilities required to operate in a lethal and effective manner. Cost and efficiency factor into these calculations but not in a large way. Decisive victory is the objective.
The American navy derives it’s lethality from the brutal and exquisite nature of its naval platforms. Aircraft carriers have occupied the central position in naval force planning for more 70 years. These 100,000 ton behemoths carry an air wing of over 70 tactical aircraft and can strike targets with precision hundreds of miles away. As threats to the carrier have mounted over time, they have been increasingly surrounded and protected by a fleet architecture of cruisers and destroyers, generally four, equipped with the latest state of the art radars and missile defense systems. They are also protected by two nuclear powered fast attack submarines that prowl the ocean in search of opposing submarines and enemy shipping.
The number of conflicts to be fought also factors in. The United States has two coasts so, for most of the 20th century and all of the 21st, the nation has maintained a fleet in both the Atlantic and Pacific oceans. This lesson was well learned in World War II when the nation faced existential threats in both oceans. To fight and win the nation’s wars the Navy requires ships of sufficient capability and quantity to move to and from battle without interruption, factoring in projected combat and material casualties. Factoring our current carrier-based force structure and near peer competitors in both the Atlantic and Pacific theaters has results in a requirement for 10 carriers, 20 cruisers, 20 destroyers and 20 fast attack submarines as well as 33 associated amphibious assault ships and 30 logistical support for a total of 163 ships to meet the bare minimum requirements to conduct combat operations. This number allows no room for extensive maintenance, reactor refuelings, combat repairs or prolonged training and readiness exercises.
However, as Mr. Easterbrook has pointed out, no one has been foolish enough to take on the United States in one theater, let alone two, since the end of World War II. Surely no one would think of doing so today, or would they?
The reason they haven’t represents the logic behind the second standard of measurement for the fleet: The number of ships required to maintain the peace. The presence of the United States Navy convinces rouge actors on a daily basis that today is not the day to start a conflict with the United States. If our Navy were to fall so low as to meet only the bare minimum requirements for combat operations it would invite our competitors to question whether the United States was ready and willing to defend its interests, just as the drawdown in US ground forces in Europe has encouraged Russian adventurism there today. Our maritime interests span the globe. Some interests are commercial, some are security based, and many are diplomatic. Today the United States services these interests by deploying Navy ships to key regions to demonstrate US resolve. These regions range from the north Atlantic to the Indian Ocean and from the Black Sea to the South China Sea. Altogether there are 15 specific geographic regions that require frequent demonstrations of US interest. These operations assure friends and allies of continued US support as well as remind competitors of the breadth and depth of US power. Some of these regions require visits from our front line capital vessels, the carriers. Most require only frigates to show our flag and convey US resolve. This has been the manner in which Pax Americana has been maintained over the past 70 years.
To service the far flung regions, scattered as they are across the globe, requires a constant cycling of ships, generally one on station, one on its way home, one training to deploy and one in maintenance. Some of these requirements can be offset with forward based naval forces such as those that operate out of Japan, Singapore, and Spain, but in the end, when you crunch all the numbers through the force structure calculator, you arrive at a the naval force of 355 ships. It’s math, and a particular simple form of it at that. However, there is another calculation, much more arcane, that needs exploring, the math behind a Navy budget.
There is a logic to the argument that to build a bigger Navy you need a bigger budget. It seems self-evident, but is not necessarily true. When the Navy decides to build one aircraft carrier for $14 billion, it is tacitly making a decision not to build the 7 destroyers or 28 frigates those same dollars could have bought. If we hold spending constant, or live with the confines of the Budget Control Act, and yet choose to buy increasingly expensive and technologically exquisite ships, then we are making a decision to buy fewer ships in the long run. This equation largely explains the decreasing size of the American fleet over the past 20 years.
Presently we buy one supercarrier every five years, and two destroyers, two submarines and four frigates every year. These are the combatants that occupy much of the conversation regarding the size and capability of the Navy. If, however, we were to purchase only one destroyer per year and invest the $2 billion saved in the construction of four additional frigates, we could rapidly grow the size of the fleet in short order. The Secretary of the Navy has stated his opposition to trading one type of ship for another, and I would agree with that. However it is possible to trade one type of ships for several of another type. This would still allow us to field high-end war fighting capabilities in balance with the need to build a larger Navy. If we were to take a really radical path and recognize that super carriers are too large, too expensive and too vulnerable to serve in combat and cease building super carriers while investing a portion of the savings in the construction of nuclear guided missile submarines to provide the lost precision strike power projection capability previously generated by the carrier’s airwing, we could afford to grow the fleet and shrink the Navy’s budget simultaneously. This is math as well and should intrigue fiscal conservatives.
In the end we must recognize that the shrinkage of the American fleet over the past generation has begun to create a power vacuum that is inviting others to challenge the longest lasting maritime peace since man took to the water in boats. If we are to maintain peace as well as remain prepared for war, we will need to grow the fleet. That we can do so while remaining within the current budget caps presents a significant opportunity for policy makers and supporters of naval power. It’s math that every American, including Mr. Easterbrook, should be able to understand.
