Ethan Allen class submarine
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 A2 missile. In the early and mid-1970s, they were further upgraded to Polaris A3s
