Submarines of the Lafayette class:[7][6]

Boats in class

The Lafayettes were decommissioned between 1986 and 1992, due to a combination of SALT II treaty limitations as the Ohio class SSBNs entered service, age, and the collapse of the Soviet Union. One (Daniel Webster) remains out of commission but converted to a Moored Training Ship (MTS-626) with the missile compartment removed. She is stationed at Nuclear Power Training Unit Charleston, South Carolina, along with USS Sam Rayburn (MTS-635).[6]

Fate

Daniel Webster was originally built with diving planes mounted on a "mini-sail" near the bow, leading to her nickname "Old Funny Fins". This configuration, unique to US submarines, was an attempt to reduce the effect of porpoising. While successful, the "mini-sail" required to contain the operating mechanism reduced hydrodynamic efficiency and lowered her overall speed. During a mid-1970s overhaul these unusual planes were removed and standard fairwater planes were installed.[5]

The Lafayettes and their successors were equipped with a hovering system to manage trim more effectively when firing missiles; this increased the missile rate of fire from one per minute to four per minute.[2]
