USS Lyndon B. Johnson

USS Lyndon B. Johnson (DDG-1002) will be the third and final Zumwalt-class destroyer built for the United States Navy. The contract to build her was awarded to Bath Iron Works located in Bath, Maine, on 15 September 2011. The award, along with funds for the construction of USS Michael Monsoor, was worth US$1.826 billion.[1][9] On 16 April 2012, Secretary of the Navy Ray Mabus announced the ship would be named Lyndon B. Johnson in honor of Lyndon B. Johnson, who served as the 36th President of the United States from 1963 to 1969. Johnson served in the Navy during World War II, when he was awarded the Silver Star, and ultimately reached the U.S. Naval Reserve rank of commander.[10] DDG-1002 is the 34th ship named by the Navy after a U.S. president.[11]

History

Lyndon B. Johnson will be a Zumwalt-class destroyer. Although 32 ships were originally planned for that class of ship, the U.S. Navy eventually reduced this number to three units.[12] Designed as multi-mission ships with an emphasis on land attack and littoral warfare,[13] the class features the tumblehome hull form, reminiscent of ironclad warships.[14] In January 2013, the Navy solicited bids for a steel deckhouse as an option for Lyndon B. Johnson instead of the composite structures of the other ships in the class.[15] This change was made in response to cost overruns for the composite structure, but due to the tight weight margins in the class, this required weight savings in other parts of the ship.[16]

In February 2015, the Navy revealed they had begun engineering studies to include an electromagnetic railgun on Lyndon B. Johnson. The Zumwalt class has been identified as more suited to use emerging technologies, like railguns, due to its superior electricity generation capability over previous destroyers and cruisers at 80 megawatts; Lyndon B. Johnson specifically was being studied because it is the latest of the class, while the previous two ships would be less likely to initially field the capability due to the testing schedule. The railgun would likely replace one of the two Advanced Gun Systems.[17] By March 2016, construction had become too far along to install the railgun during building, but it can still be added later.[18]

In September 2015, it was reported that U.S. Department of Defense officials were considering terminating funding for Lyndon B. Johnson prior to her completion.[19] Although considered as a cost-saving measure, cancelling the third Zumwalt ship at that stage was likely not possible, and might have ended up actually costing more after paying program shutdown costs and contract termination penalties.[20] By December 2015, the Pentagon had decided in favor of keeping the ship.[21]

The ship's two AGSs can only fire the LRLAP round. LRLAP procurement was cancelled in 2016,[22][23] and the Navy has no immediate plan to replace it.[8] As such, the guns cannot currently be used and the ship cannot provide naval gunfire support. The Navy has re-purposed the Zumwalt class to surface warfare.[24]

The ceremonial keel laying of Lyndon B. Johnson took place on 30 January 2017, by which time construction of the ship was over half finished.[25] The ship was launched in Bath, Maine, on 9 December 2018,[3][26] and christened on 27 April 2019, by Johnson's daughters, Luci and Lynda.[4][27]

Bath Iron Works

Bath Iron Works (BIW) is a major United States shipyard located on the Kennebec River in Bath, Maine, founded in 1884 as Bath Iron Works, Limited. BIW has built private, commercial, and military vessels, most of which have been ordered by the United States Navy. The shipyard has built and sometimes designed battleships, frigates, cruisers, and destroyers, including the Arleigh Burke class which are currently among the world's most advanced surface warships.

Since 1995, Bath Iron Works has been a subsidiary of General Dynamics, the fifth-largest defense contractor in the world as of 2008. During World War II, ships built at BIW were considered to be of superior toughness by sailors and Navy officials, giving rise to the phrase "Bath-built is best-built."

Guided missile destroyer

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.

In addition to the guns, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap.

United States ship naming conventions

United States ship naming conventions for the U.S. Navy were established by Congressional action at least as early as 1862. Title Thirteen, Chapter Six, of the United States Code, enacted in that year, reads, in part,

The vessels of the Navy shall be named by the Secretary of the Navy under direction of the President according to the following rule:

Sailing-vessels of the first class shall be named after the States of the Union, those of the second class after the rivers, those of the third class after the principal cities and towns and those of the fourth class as the President may direct.

Further clarification was made by executive order of President Theodore Roosevelt in 1907. However, elements had existed since before his time. If a ship is reclassified, for example a destroyer is converted to a mine layer, it retains its original name.

Zumwalt-class destroyer

The Zumwalt-class destroyer is a class of United States Navy guided missile destroyers designed as multi-mission stealth ships with a focus on land attack. It is a multi-role class that was designed for secondary roles of surface warfare and anti-aircraft warfare and originally designed with a primary role of naval gunfire support. It was intended to take the place of battleships in meeting a congressional mandate for naval fire support. The ship is designed around its two Advanced Gun Systems, their turrets and magazines, and unique Long Range Land Attack Projectile (LRLAP) ammunition. LRLAP procurement was cancelled, rendering the guns unusable, so the Navy re-purposed the ships for surface warfare. A National Review article by Mike Fredenburg calls the Zumwalts "an unmitigated disaster". The class design emerged from the DD-21 "land attack destroyer" program as "DD(X)".

These ships are classed as destroyers, but they are much larger than any other active destroyer or cruiser. The vessels' distinctive appearance results from the design requirement for a low radar cross-section (RCS). The Zumwalt-class has a wave-piercing tumblehome hull form whose sides slope inward above the waterline, which dramatically reduces RCS by returning much less energy than a conventional flare hull form. The appearance has been compared to that of the historic USS Monitor and her famous antagonist CSS Virginia.The class has an integrated power system that can send electricity from its turbo-generators to the electric drive motors or weapons, the Total Ship Computing Environment Infrastructure (TSCEI), automated fire-fighting systems, and automated piping rupture isolation. The class is designed to require a smaller crew and to be less expensive to operate than comparable warships.

The lead ship is named Zumwalt for Admiral Elmo Zumwalt and carries the hull number DDG-1000. Originally, 32 ships were planned, with $9.6 billion research and development costs spread across the class. As costs overran estimates, the quantity was reduced to 24, then to 7, and finally to 3, significantly increasing the cost per ship to $4.24 billion (excluding R&D costs) and well exceeding the per-unit cost of a nuclear-powered Virginia-class submarine ($2.688 billion). The dramatic per-unit cost increases eventually triggered a Nunn–McCurdy Amendment breach and cancellation of further production. In April 2016, the total program cost was $22.5 billion, with an average cost of $7.5 billion per ship.
