Ethan Allen (1738–1789) was an early American and Vermont revolutionary.

The Benjamin Franklin-class submarine was a group of US ballistic missile submarines that were in Navy service from the 1960s–2000s. The class was an evolutionary development from the earlier James Madison class of fleet ballistic missile submarine. Having quieter machinery and other improvements, it is considered a separate class. A subset of this class is the re-engineered 640 class starting with USS George C. Marshall. The primary difference was that they were built under the new SUBSAFE rules after the loss of USS Thresher, earlier boats of the class had to be retrofitted to meet SUBSAFE requirements. The Benjamin Franklin class, together with the George Washington, Ethan Allen, Lafayette, and James Madison classes, composed the "41 for Freedom" that was the Navy's primary contribution to the nuclear deterrent force through the late 1980s. This class and the James Madison class are combined with the Lafayettes in some references.
The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs). Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. Navy. They are the world's third-largest submarines, behind the Russian Navy's Soviet-designed 48,000-ton Typhoon class and 24,000-ton Borei class. At 24 Trident II missiles apiece, Ohio-class boats carry more missiles than either the Borei class or the Typhoon class (20).
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles.
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. The United States Navy's hull classification symbols for ballistic missile submarines are SSB and SSBN – the SS denotes submarine, the B denotes ballistic missile, and the N denotes that the submarine is nuclear powered. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect, thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence.
The George Washington class was a class of nuclear-powered ballistic missile submarines deployed by the United States Navy. George Washington, along with the later Ethan Allen, Lafayette, James Madison, and Benjamin Franklin classes, comprised the "41 for Freedom" group of submarines that represented the Navy's main contribution to the nuclear deterrent force through the late 1980s.
41 for Freedom refers to the US Navy Fleet Ballistic Missile (FBM) submarines from the George Washington, Ethan Allen, Lafayette, James Madison, and Benjamin Franklin classes. All of these submarines were commissioned 1959–1967, as the goal was to create a credible, survivable sea-based deterrent as quickly as possible. These submarines were nicknamed "41 for Freedom" once the goal of 41 nuclear-powered ballistic missile submarines (SSBNs) was established in the early 1960s. The 1972 SALT I Treaty limited the number of American submarine-launched ballistic missile tubes to 656, based on the total missile tubes of the forty-one submarines, in line with the treaty's goal of limiting strategic nuclear weapons to the number already existing.
Two ships of the United States Navy have been named USS Ethan Allen in honor of Ethan Allen, the guerrilla leader of the Green Mountain Boys.
USS Ethan Allen (SSBN-608), lead ship of her class, was the second ship of the United States Navy to be named for American Revolutionary War hero Ethan Allen.
The Ethan Allen class of fleet ballistic missile submarine was an evolutionary development from the George Washington class. The Ethan Allen, together with the George Washington, Lafayette, James Madison, and Benjamin Franklin classes comprised the "41 for Freedom" that were the Navy's main contribution to the nuclear deterrent force through the late 1980s.
USS Thomas A. Edison (SSBN-610), an Ethan Allen-class nuclear-powered ballistic missile submarine, was the second ship of the United States Navy to be named for the inventor, Thomas Edison (1847–1931).
The Lafayette class of submarine was an evolutionary development from the Ethan Allen class of fleet ballistic missile submarine, slightly larger and generally improved. This class, together with the George Washington, Ethan Allen, James Madison, and Benjamin Franklin classes, composed the "41 for Freedom," the Navy's primary contribution to the nuclear deterrent force through the late 1980s. The James Madison and Benjamin Franklin classes are combined with the Lafayettes in some references.
The James Madison class of submarine was an evolutionary development from the Lafayette class of fleet ballistic missile submarine. They were identical to the Lafayettes except for being initially designed to carry the Polaris A-3 missile instead of the earlier A-2. This class, together with the George Washington, Ethan Allen, Lafayette, and Benjamin Franklin classes, composed the "41 for Freedom" that was the Navy's primary contribution to the nuclear deterrent force through the late 1980s. This class and the Benjamin Franklin class are combined with the Lafayettes in some references.
Two ships of the United States Navy have been named USS Sam Houston.
USS Carbonero (SS/AGSS-337) was a Balao-class submarine, the first ship of the United States Navy to be named for the carbonero, a salt-water fish found in the West Indies.
United States ship naming conventions for the U.S. Navy were established by congressional action at least as early as 1862. Title 13, section 1531, of the U.S. 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.
Commander, Submarine Force Atlantic (COMSUBLANT) is the Submarine Force U.S. Atlantic Fleet type commander under the United States Fleet Forces Command.
The Columbia-class submarine is an upcoming class of nuclear submarines designed to replace the Ohio-class ballistic missile submarines in the United States Navy. The first submarine officially began construction on 1 October 2020, and is scheduled to enter service in 2031.
Charles L. Munns, retired as a Vice Admiral in the United States Navy. Munns held several posts including Commander, United States Submarine Forces (COMNAVSUBFOR) and Commander, Submarine Force Atlantic (COMSUBLANT). Munns served as commander of the U.S. submarine force from 2004-2007.
