Navy Force Structure And Shipbuilding Plans

Discusses the U.S. Navy¿s proposed FY 2010 budget requests funding for eight new Navy ships. This total includes two relatively expensive, high-capability combatant ships (a Virginia-class attack submarine and a DDG-51 class Aegis destroyer) and six relatively inexpensive ships (three Littoral Combat Ships [LCSs], two TAKE-1 auxiliary dry cargo ships, and one Joint High Speed Vessel [JHSV]). Concerns about the Navy¿s prospective ability to afford its long-range shipbuilding plan, combined with year-to-year changes in Navy shipbuilding plans and significant cost growth and other problems in building certain new Navy ships, have led to concerns about the status of Navy shipbuilding and the potential future size and capabilities of the fleet.

In February 2008, as part of its proposed FY2009 budget, the Navy submitted to Congress the FY2009 version of its annual 30-year shipbuilding plan. The 30-year plan is intended to support the Navy's goal of achieving and maintaining a 313-ship fleet. The Navy first presented the 313-ship plan to Congress in February 2006. The increase in the Navy's estimated cost for implementing the plan is so large that the Navy no longer appears to have a clearly identifiable, announced strategy for generating the funds needed to implement the 30-year plan, at least not without significantly reducing funding for other Navy programs or increasing the Navy's programmed budget in coming years by billions of dollars per year. Concerns about the Navy's prospective ability to afford the 30-year shipbuilding plan, combined with year-to-year changes in Navy shipbuilding plans and significant cost growth and other problems in building certain new Navy ships, have led to strong concerns among some Members about the status of Navy shipbuilding and the potential future size and capabilities of the fleet. As a consequence of these strong concerns, some Members in hearings this year on the Navy's proposed FY2009 budget have strongly criticized aspects of the Navy's shipbuilding plan and indicated that they are considering making changes to the plan. Some Members in the House, for example, have indicated that they are considering the option of not procuring a third DDG-1000 class destroyer in FY2009, as the Navy has requested, and using the funding programmed for that ship to instead procure other kinds of ships for the Navy. This report will be updated as events warrant.

Updated 12/10/2020: In December 2016, the Navy released a force-structure goal that callsfor achieving and maintaining a fleet of 355 ships of certain types and numbers. The 355-shipgoal was made U.S. policy by Section 1025 of the FY2018 National Defense AuthorizationAct (H.R. 2810/P.L. 115- 91 of December 12, 2017). The Navy and the Department of Defense(DOD) have been working since 2019 to develop a successor for the 355-ship force-level goal.The new goal is expected to introduce a new, more distributed fleet architecture featuring asmaller proportion of larger ships, a larger proportion of smaller ships, and a new third tier oflarge unmanned vehicles (UVs). On December 9, 2020, the Trump Administration released a document that can beviewed as its vision for future Navy force structure and/or a draft version of the FY202230-year Navy shipbuilding plan. The document presents a Navy force-level goal that callsfor achieving by 2045 a Navy with a more distributed fleet architecture, 382 to 446 mannedships, and 143 to 242 large UVs. The Administration that takes office on January 20, 2021,is required by law to release the FY2022 30-year Navy shipbuilding plan in connection withDOD's proposed FY2022 budget, which will be submitted to Congress in 2021. In preparingthe FY2022 30-year shipbuilding plan, the Administration that takes office on January 20,2021, may choose to adopt, revise, or set aside the document that was released on December9, 2020. The Navy states that its original FY2021 budget submission requests the procurement ofeight new ships, but this figure includes LPD-31, an LPD-17 Flight II amphibious ship thatCongress procured (i.e., authorized and appropriated procurement funding for) in FY2020.Excluding this ship, the Navy's original FY2021 budget submission requests the procurementof seven new ships rather than eight. In late November 2020, the Trump Administrationreportedly decided to request the procurement of a second Virginia-class attack submarinein FY2021. CRS as of December 10, 2020, had not received any documentation from theAdministration detailing the exact changes to the Virginia-class program funding linesthat would result from this reported change. Pending the delivery of that information fromthe administration, this CRS report continues to use the Navy's original FY2021 budgetsubmission in its tables and narrative discussions.

This report provides background information and presents potential issues for Congress concerning the Navy's ship force-structure goals and shipbuilding plans. The planned size of the Navy, the rate of Navy ship procurement, and the prospective affordability of the Navy's shipbuilding plans have been matters of concern for the congressional defense committees for the past several years. Decisions that Congress makes on Navy shipbuilding programs can substantially affect Navy capabilities and funding requirements, and the U.S. shipbuilding industrial base.

The Navy in February 2006 proposed to maintain in coming years a fleet of 313 ships, including, among other things, 11 aircraft carriers, 48 attack submarines (SSNs), 88 cruisers and destroyers, 55 Littoral Combat Ships (LCSs), 31 amphibious ships, and a Maritime Prepositioning Force (Future), or MPF(F), squadron with 12 new-construction amphibious and sealift-type ships. The Navy says that for its shipbuilding plans to be affordable and executable, the Navy needs to control certain non-shipbuilding expenditures and build ships within estimated costs. The Navy's shipbuilding plans raise potential issues regarding the shipbuilding industrial base, particularly in the areas of the submarine design and engineering base, and the surface combatant construction base.

The current and planned size and composition of the Navy, the rate of Navy ship procurement, and the prospective affordability of the Navy's shipbuilding plans have been oversight matters for the congressional defense committees for many years. The Navy's proposed FY2018 budget, as amended on May 24, 2017, requests the procurement of nine new ships, including one Gerald R. Ford (CVN-78) class aircraft carrier, two Virginia-class attack submarines, two DDG-51 class destroyers, two Littoral Combat Ships (LCSs), one TAO-205 class oiler, and one towing, salvage, and rescue ship. On December 15, 2016, the Navy released a new force-structure goal that calls for achieving and maintaining a fleet of 355 ships of certain types and numbers. Key points about this new 355-ship force-level goal include the following: The 355-ship force-level goal is the result of a Force Structure Assessment (FSA) conducted by the Navy in 2016. The Navy conducts an FSA every few years, as circumstances require, to determine its force-structure goal. The new 355-ship force-level goal replaces a 308-ship force-level goal that the Navy released in March 2015. The actual size of the Navy in recent years has generally been between 270 and 290 ships. 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), while the Trump campaign organization's 350-ship goal appears to have a different origin. Compared to the previous 308-ship force-level goal, the new 355-ship force-level goal includes 47 additional ships, or about 15% more ships. More than 47 ships, however, would need to be added to the Navy's 30-year shipbuilding plan to achieve and maintain the Navy's 355-ship fleet, unless the Navy extends the service lives of existing ships beyond currently planned figures and/or reactivates recently retired ships: CRS estimates that 57 to 67 ships would need to be added to the Navy's FY2017 30-year (FY2017-FY2046) shipbuilding plan to achieve the Navy's 355-ship fleet and maintain it through the end of the 30-year period (i.e., through FY2046).
