    Navy Columbia (SSBN-826) Class Ballistic Missile Submarine Program: Background and Issues for Congress Updated September 14, 2021 Congressional Research Service https://crsreports.congress.gov R41129 Navy Columbia (SSBN-826) Class Ballistic Missile Submarine Program Summary The Navy’s Columbia (SSBN-826) class ballistic missile submarine (SSBN) program is a program to design and build a class of 12 new SSBNs to replace the Navy’s current force of 14 aging Ohio-class SSBNs. Since 2013, the Navy has consistently identified the Columbia-class program as the Navy’s top priority program. The Navy procured the first Columbia-class boat in FY2021 and wants to procure the second boat in the class in FY2024. The Navy’s proposed FY2022 budget requests $3,003.0 (i.e., $3.0 billion) in procurement funding for the first Columbia-class boat and $1,644.0 million (i.e., about $1.6 billion) in advance procurement (AP) funding for the second boat, for a combined FY2022 procurement and AP funding request of $4,647.0 million (i.e., about $4.6 billion). The Navy’s FY2022 budget submission estimates the procurement cost of the first Columbia- class boat at $15,030.5 million (i.e., about $15.0 billion) in then-year dollars, including $6,557.6 million (i.e., about $6.60 billion) in costs for plans, meaning (essentially) the detail design/nonrecurring engineering (DD/NRE) costs for the Columbia class. (It is a long-standing Navy budgetary practice to incorporate the DD/NRE costs for a new class of ship into the total procurement cost of the first ship in the class.) Excluding costs for plans, the estimated hands-on construction cost of the first ship is $8,473.0 million (i.e., about $8.5 billion).

  • Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress
    Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress September 16, 2021 Congressional Research Service https://crsreports.congress.gov RL32665 Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress Summary The current and planned size and composition of the Navy, the annual rate of Navy ship procurement, the prospective affordability of the Navy’s shipbuilding plans, and the capacity of the U.S. shipbuilding industry to execute the Navy’s shipbuilding plans have been oversight matters for the congressional defense committees for many years. In December 2016, the Navy released a force-structure goal that calls for achieving and maintaining a fleet of 355 ships of certain types and numbers. The 355-ship goal was made U.S. policy by Section 1025 of the FY2018 National Defense Authorization Act (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 a smaller proportion of larger ships, a larger proportion of smaller ships, and a new third tier of large unmanned vehicles (UVs). On June 17, 2021, the Navy released a long-range Navy shipbuilding document that presents the Biden Administration’s emerging successor to the 355-ship force-level goal. The document calls for a Navy with a more distributed fleet architecture, including 321 to 372 manned ships and 77 to 140 large UVs. A September 2021 Congressional Budget Office (CBO) report estimates that the fleet envisioned in the document would cost an average of between $25.3 billion and $32.7 billion per year in constant FY2021 dollars to procure.

  • The Law of Submarine Warfare Today
    Jacobson 205 Chapter VIII The Law of Submarine Warfare Today by Jon L. Jacobson* Introduction he roles of military submarines have evolved throughout the twentieth T century. In wartime, these roles have included coastal defense, harassment of enemy fleets, and, especially in World War II, hunting and destroying the seaborne commerce that supported the enemy's war efforts. Today, two principal roles for u.s. submarines, at least in any future war with the Soviet Union, are probably as anti-submarine weapons (attack submarines) and as strategic weapons platforms (ballistic missile submarines). Other missions, however, could include coastal defense, attacks on the enemy's surface fleet, projection of force ashore, and commerce warfare.1 The laws of war have never been comfortable with the submarine's unique combination of stealth and vulnerability. As will be explained below, it is this peculiar mix of strength and weakness that can be blamed as the root cause of the legal dilemma, particularly as it relates to the submarine's role as a commerce raider. The legal responses to this twentieth-century weapons platform have ranged from early proposals for its abolition to justification of its use under the rules of reprisal to tolerance of it as an effective war machine with characteristics that regrettably require some adjustments in the traditional laws of war. The U.s. Navy's new Commander's Handbook on the Law of Naval Operations (NWP 9) includes references to the laws of naval warfare that specifically address the submarine weapons system and also rules that apply, or can apply, to submarines and their roles in wartime.

  • NATIONAL REGISTER ELIGIBILITY ASSESSMENT VESSEL: Ex- USS Pigeon (ASR-21)
    NATIONAL REGISTER ELIGIBILITY ASSESSMENT VESSEL: ex- USS Pigeon (ASR-21) USS Pigeon (ASR-21) underway. Pigeon was the first of two catamaran-hulled SRVs. Location and date are unknown. http://www.navsource.org/archives/09/32/3221.htm Vessel History The USS Pigeon (ASR-21) was the first of two catamaran-hulled submarine rescue vessels commissioned by the U.S. Navy in 1973. Alabama Drydock and Shipbuilding Company in Mobile, Alabama won the construction contract on November 15, 1967. Its keel was laid on July 17, 1968 and it was launched on August 13, 1969. Pigeon was commissioned on April 28, 1973. It was the navy’s third vessel that carried the name. Pigeon was assigned to the U.S. Navy’s Pacific Fleet, spending most of its career homeported at Naval Base San Diego. Its sistership, the USS Ortolan (ASR-22) was assigned to the U.S. Navy’s Atlantic Fleet in Norfolk, Virginia. The Pigeon spent the next two decades in readiness for the submarine disaster that fortunately never occurred. It spent frequent periods at sea conducting drills and training, including general training in saturation diving. The Pigeon successfully performed the navy’s first open ocean working saturation dive when it recovered the engine and ejection seat of an F-14 jet fighter that had crashed in 730 feet of water. The construction and design of the ships were a result of the loss of the nuclear-submarine USS Thresher (SSN-593) in the deep waters of the North Atlantic in April 1963, and the subsequent loss of a hydrogen bomb in the western Mediterranean off of Spain’s coast in January 1966.

  • The Strategic Missile Submarine Force and Apl's Role in Its Development
    JOHNM. WATSON THE STRATEGIC MISSILE SUBMARINE FORCE AND APL'S ROLE IN ITS DEVELOPMENT The U.S. Navy's Fleet Ballistic Missile program is one of the largest, most successful weapons systems development programs in our country's history. In the thirty-seven-year span of this program, three generations of increasingly capable weapons systems (Polaris, Poseidon, and Trident) have been developed and deployed. Contributions to these systems have spawned three of the technical departments at the Applied Physics Laboratory: Space, Strategic Systems, and Submarine Technology. INTRODUCTION The U.S. Navy's Fleet Ballistic Missile (FBM) program, begun in 1955, is recognized today as the cornerstone of the U.S. nuclear strategic deterrent. The submarine­ launched ballistic missile (SLBM) and its nuclear-powered submarine launching platform, the SSBN (submersible ship, ballistic, nuclear), provide a mobile, stealthy, long­ patrol-duration weapon system with enormous retaliation potential. This system provides a significant deterrent advantage over land-based missiles or aircraft systems because of its mobility and its ability to avoid detection in vast ocean patrol areas, thus remaining invulnerable to a surprise attack. The Navy's Strategic Systems Program (SSP), formerly the Special Projects Office (SPO) and the Strategic Systems Program Office (SSPO), has overseen the development and operational deployment of three generations of increasingly capable weapon systems (Po­ laris, Poseidon, and Trident), with six variants of the SLBM (Figs. 1 and 2). The success of this program is largely due Figure 1. A Trident II (D5) submarine-launched ballistic missile (SLBM) is launched off the coast of Florida.

Patton, Jr. It’s not the strongest that survive, but the ones most responsive to change. CHARLES DARWIN The Department of Defense is sometimes guilty of glomming onto a buzzword or catchy phrase and wearing it thin. “Revolution in Military Affairs,” or RMA (a term derived, incidentally, from Soviet military writings concerning a “military- technical revolution”) certainly came close to crossing that threshold. Today, the word “transformation”—a marvelously useful and intellectually descriptive word—could similarly be at risk of exhaustion. When such a phrase represents an apparently desirable property, there exists a tendency to attach that phrase to every conceivable defense system, thereby en- hancing the program’s attractiveness to senior decision makers.
