As of 2021, the US Naval Submarine Force maintains a fleet of 71 submarines. These submarines are divided into two primary categories: ballistic missile submarines (SSBNs) and guided-missile submarines (SSGNs). Let’s delve into each category to gain a better understanding of their purpose and capabilities.
Ballistic missile submarines (SSBNs) form the backbone of the US strategic nuclear deterrent. These submarines are armed with ballistic missiles capable of carrying nuclear warheads, thus serving as a crucial component of the nation’s nuclear triad. Currently, the US Navy operates a total of 14 Ohio-class submarines, with future plans to replace them with the Columbia-class submarines. The Columbia-class will consist of 12 submarines and is expected to enter service in the late 2020s. These submarines patrol the world’s oceans silently, ready to provide a credible and swift response should the need arise.
Guided-missile submarines (SSGNs) are multi-mission platforms that can engage in both conventional and strategic warfare scenarios. The US Navy currently has 4 Ohio-class SSGNs in service. These submarines were initially built as SSBNs and were later converted to carry guided missiles instead of ballistic missiles. They are capable of launching a variety of missiles, including Tomahawk land-attack cruise missiles. With their versatility and stealth capabilities, SSGNs provide flexible options to commanders on the battlefield.
Additionally, the US Naval Submarine Force operates fast-attack submarines (SSNs), which are specifically designed to engage both surface and subsurface targets in various mission areas. These submarines are known for their capability to project power worldwide and are integral in gathering intelligence, surveillance, and reconnaissance (ISR) data. The US Navy currently operates a fleet of 53 fast-attack submarines, consisting of both Los Angeles-class submarines and Virginia-class submarines. The Virginia-class submarines, with their sophisticated technology and enhanced capabilities, are planned to replace the aging Los Angeles-class submarines.
It is important to note that the size and composition of the US Naval Submarine Force may change over time due to retirement, decommissioning, or construction of new submarines. The US military regularly assesses its force requirements based on evolving threats and national security strategies. The US Navy’s commitment to maintaining a robust and technologically advanced submarine force remains steadfast.
In conclusion, the US Naval Submarine Force boasts an impressive fleet of 71 submarines, divided into ballistic missile submarines (SSBNs), guided-missile submarines (SSGNs), and fast-attack submarines (SSNs). These submarines play a vital role in safeguarding national security interests, projecting power, and ensuring a credible nuclear deterrent. With ongoing modernization efforts and the introduction of new submarine classes, the US Navy remains at the forefront of undersea warfare capabilities.
