List of submarines of the United States Navy

USS Nautilus SSN-571 - 0857101

List of Submarines of the United States Navy encompasses the various classes and individual vessels that have served or are currently serving in the United States Navy's submarine fleet. Submarines have been a component of the U.S. Navy since the early 20th century, playing critical roles in both World Wars, the Cold War, and modern global operations. This article provides an overview of the types, classes, and notable submarines that have defined American undersea warfare capabilities.

History

The history of submarines in the United States Navy dates back to the American Civil War, with experimental submarine designs like the CSS Hunley. However, it wasn't until the early 20th century that the U.S. Navy formally incorporated submarines into its fleet, beginning with vessels like USS Holland (SS-1). Throughout World War I, World War II, the Cold War, and into the modern era, submarines have evolved from coastal defense units to nuclear-powered vessels capable of launching ballistic missiles and conducting covert operations.

Classes of Submarines

The U.S. Navy's submarine fleet has evolved through several classes, each reflecting advancements in technology, strategy, and naval warfare.

Diesel-Electric Submarines

Before the advent of nuclear power, submarines were primarily diesel-electric powered. Notable classes include:

• Gato-class
• Balao-class
• Tench-class

These classes served prominently during World War II, with many vessels seeing action in the Pacific Theater.

Nuclear-Powered Submarines

The introduction of nuclear power revolutionized submarine design and capabilities. Key classes include:

• Nautilus-class (SSN-571) – The world's first operational nuclear-powered submarine.
• Skipjack-class – Introduced the teardrop hull design.
• Los Angeles-class – One of the largest classes of nuclear-powered fast attack submarines.
• Ohio-class – Fleet ballistic missile submarines, part of the U.S. nuclear triad.
• Virginia-class – The latest class of nuclear-powered fast attack submarines.

Special Mission and Experimental Submarines

The U.S. Navy has also operated submarines designed for special missions or experimental purposes, such as:

• Seawolf-class – A class known for its advanced acoustic performance and stealth.
• NR-1 Deep Submergence Craft – A nuclear-powered submarine designed for deep-sea research and recovery operations.

Notable Submarines

Several U.S. Navy submarines have gained fame due to their design, missions, or historical significance, including:

• USS Nautilus (SSN-571) – The first nuclear-powered submarine.
• USS Thresher (SSN-593) – Lost in 1963, leading to significant safety improvements in submarine design.
• USS Scorpion (SSN-589) – Lost in 1968 under mysterious circumstances.
• USS Triton (SSRN-586) – First submarine to execute a submerged circumnavigation of the Earth.

Future Developments

The U.S. Navy continues to advance submarine technology with plans for new classes and upgrades to existing vessels. The focus remains on enhancing stealth, sensor capabilities, and weapons systems to maintain undersea dominance in global waters.
