The Ethan Allen class of fleet ballistic missile submarine was an evolutionary development from the George Washington class. Together with the George Washington, the Lafayette, the James Madison, and the Benjamin Franklin classes, they comprised the "41 for Freedom."
Rather than being designed as Skipjack-class attack submarines with a missile compartment added, the Ethan Allens were designed from scratch as fleet ballistic missile submarines carrying the Polaris A-2 missile. In the early and mid-1970s, they were further upgraded to Polaris A3s. They were unable to be modified to carry the larger diameter Poseidon missile,[1] and were refitted as SSNs (attack submarines), with the missile tubes being filled with concrete and their fire control systems being removed in the early 1980s. Two were further converted to carry SEALs, accommodating 67 troops each. The Ethan Allen class submarines were decommissioned between 1983 and 1992.[2] All have now been broken up.
