The U.S. Navy has a balanced fleet, but it wants to grow bigger and better. Will the budget allow both?

Maritime Reporter's March 2017 cover story on the U.S. Navy was all about the numbers. There exists several plans to grow the fleet beyond the current number of 308 ships, the Mitre recommendation of 414 ships, the Center for Strategic and Budgetary Assessment 340-ship proposal, and the Navy’s decision to grow the fleet to 355 ships, and the Trump administration’s 350.
With so many numbers being bandied about, there are even more suggestions on how to get there. The decision to expand the number of ships is based on sound analysis, and most of the suggested numbers are the result of a thoughtful examination of the requirement and the reasonable pathways to achieving growth.
According to a report to Congress by the Congressional Research Service, the figure of 355 ships appears close to an objective of building toward a fleet of 350 ships that was announced by the Trump campaign organization during the 2016 presidential election campaign. “The 355-ship goal, however, reflects the national security strategy and national military strategy that were in place in 2016 (i.e., the Obama Administration’s national security strategy and national military strategy).”
But no matter how you slice it and dice it, there’s a huge cost. 
And those who want to point to instantaneous gratification, and see an immediate growth in fleet size, will not find it in this most recent budget submission to the Congress.
The current Presidential Budget delivered to Capitol Hill does call for an increase in defense spending. This year’s budget submission is about readiness, not new construction.
The non-partisan Congressional Research Service (CRS) estimates that “procuring the 57 to 67 ships that would need to be added to the Navy’s FY2017 30-year shipbuilding plan to achieve the Navy’s 355-ship fleet and maintain it through FY2046 would notionally cost an average of roughly $4.6 billion to $5.1 billion per year in additional shipbuilding funds over the 30-year period, using today’s shipbuilding costs.”
There are also time and industrial capacity constraints to achieving the 355-ship objective. “Even with increased shipbuilding rates, achieving certain parts of the 355-ship force-level goal could take many years,” CRS reports. “For example, the 355-ship force-level goal includes a goal of 12 aircraft carriers. Increasing aircraft carrier procurement from the current rate of one ship every five years to one ship every three years would achieve a 12-carrier force on a sustained basis by about 2030. As another example, the 355-ship force level includes a goal of 66 attack submarines. Increasing attack submarine procurement to a rate of three attack submarines (or two attack submarines and one ballistic missile submarine) per year could achieve a 65-boat SSN force by the late 2030s. CBO estimates that the earliest the Navy could achieve the 355-ship fleet would be 2035.”
That means manning and tooling up the nation’s shipbuilders and suppliers.
“Ramping up to higher rates of shipbuilding would require additional tooling and equipment at some shipyards and some supplier firms. Additional production and supervisory workers would need to be hired and trained at shipyards and supplier firms. Depending on their specialties, newly hired workers could be initially less productive per unit of time worked than more experienced workers. Given the time needed to increase tooling and hire and train new workers, some amount of time would be needed to ramp up to higher shipbuilding rates—production could not jump to higher rates overnight,” the CRS report said. “Some parts of the shipbuilding industrial base could face more challenges than others in ramping up to the higher production rates required to build the various parts of the 355-ship fleet.”
CRS cited a non-partisan Congressional Budget Office Costs of Building a 355-Ship Navy report, which it submitted to Congress in April 2017. 
“All seven shipyards would need to increase their workforces and several would need to make improvements to their infrastructure in order to build ships at a faster rate. However, certain sectors face greater obstacles in constructing ships at faster rates than others: Building more submarines to meet the goals of the 2016 force structure assessment would pose the greatest challenge to the shipbuilding industry. Increasing the number of aircraft carriers and surface combatants would pose a small to moderate challenge to builders of those vessels. Finally, building more amphibious ships and combat logistics and support ships would be the least problematic for the shipyards. The workforces across those yards would need to increase by about 40 percent over the next 5 to 10 years. Managing the growth and training of those new workforces while maintaining the current standard of quality and efficiency would represent the most significant industrywide challenge. In addition, industry and Navy sources indicate that as much as $4 billion would need to be invested in the physical infrastructure of the shipyards to achieve the higher production rates required under the [notional] 15-year and 20-year [buildup scenarios examined by CBO]. Less investment would be needed for the [notional] 25-year or 30-year [buildup scenarios examined by CBO].”
But the obstacles are not insurmountable, and frankly the kind of problem that the Navy and industry wants to solve.
The Navy currently has “hot production lines. “Our facilities are in pretty good shape,” said then Assistant Secretary of the Navy (now the acting secretary) Sean Stackley at the Surface Navy Association’s annual symposium. “Industry’s going to have to go out and procure special tooling associated with going from current production rates to a higher rate, but I would say that’s easily done,” he said. 
“My sense is that the industrial base will size to the demand signal,” said Rear Adm. William Gallinis, the program executive officer for ships at the SNA symposium. “We just need to be mindful of how we transition to that increased demand signal,” he said. 
Also speaking at the SNA event, Adm. William Moran, the Vice Chief of Naval Operations said the priority is readiness. Before inauguration, Moran said the Trump transition team inquired about what the Navy could do with more money right away. “The answer was not, ‘Buy more ships.’ The answer was, ‘Make sure that the 274 that we had were maintained and modernized to provide 274 ships’ worth of combat time.’ Then, we’ll start buying more ships,” he said.
Chief of Naval Operations Adm. John Richardson said the nation needs a more powerful Navy, on the order of 350 ships, that includes a combination of manned and unmanned systems. “More platforms are necessary but not sufficient. The Navy must also incorporate new technologies and new operational concepts.” 
 “As we increase our naval power, our focus cannot be on some distant goal decades in the future. The Navy must get to work now to both build more ships, and to think forward - innovate - as we go,” Richardson said. “To remain competitive, we must start today and we must improve faster.” 
“I believe that strong naval forces - maritime forces - are uniquely suited to help manage the increasing pace and complexity of change, by virtue of the uniquely productive relationships that are possible, and by virtue of strong history and advocacy for behavior in accordance with a well understood and agreed-to set of rules,” said Richardson. “And navies can do this in a way that preserves the opportunity for growth, and yes, the opportunity for competition, but also in a way that avoids conflict and violence.” 
The U.S. Navy operate as a balanced mix of aircraft carriers, expeditionary warfare platforms, combatants and auxiliaries. Here are some of the key Navy ship programs:
Nimitz-class aircraft carriers
The Nimitz-class supercarriers are a class of 10 nuclear-powered aircraft carriers in service with the United States Navy. These ships are 1,092 feet long with a displacement of over 100,000 tons. The two A4W pressurized water reactors drive four propeller shafts for a maximum speed of over 30 knots. The reactors can operate for more than 20 years without refueling. All ten carriers were constructed by Newport News Shipbuilding Company in Virginia. USS Nimitz was commissioned on May 3, 1975, and the final ship in the class, USS George H.W. Bush, joined the fleet in 2009. The ship has a crew of about 5,500 including the airwing of about 90 aircraft.

Littoral combat ships and frigates
Littoral Combat Ship (LCS)
The Littoral Combat Ship is a fast focused-mission combatant designed to address the asymmetric threats in littoral waters on mines, quiet diesel submarines and swarms of fast armed boats. LCS is being built in two variants. The Freedom-class variant is a monohull, built in Marinette, Wisconsin. The Independence-class is a trimaran, built in Mobile, Ala. Both have core systems to fight and defend the ship, and are modular and can be configured with mission packages to address those three asymmetric threats. The crews rotate between their homeport and the forward deployed ships. The Navy has a requirement for 52 LCS.

Frigate (FF)
The next-generation frigate (FF) is currently envisioned to be a modified multi-mission littoral combat ship (LCS) with enhanced lethality and survivability in support of surface warfare (SUW) and anti-submarine warfare (ASW) missions. The FF will operate independently, as part of a strike group, and serve as an escort. Both the Freedom and Independence variant may be selected for the frigate, but the COMBATSS-21 (an Aegis Weapon System derivative) has been selected as the combat management system. The existing LCS training and maintenance infrastructure will be able to support the frigate program.
