USS Miami (SSN-755)

History of USS Miami (SSN-755)

The USS Miami was part of the formidable Los Angeles class of attack craft that appeared in 1976 and beyond, with a total of 62 completed ships. Her construction contract was awarded to General Dynamics Electric Boat Company on November 28, 1983, and her keel was laid on October 24, 1986.

She was subsequently launched on November 12, 1988, and enlisted in the U.S. Navy on June 30, 1990, making her home in Groton Harbor, Connecticut.

When built, the USS Miami will displace 5,840 tons under light load and 6,245 tons under full load. She had a barrel length of 362 feet, a beam of 32 feet 10 inches, and a draft of 30 feet 10 inches. Her propulsion is based on a General Electric GE PWR S6G nuclear reactor with two 35,000-horsepower turbines and a 325-horsepower auxiliary engine attached to a shaft.

Miami consists of a crew of 110, including 12 officers.

As an attack submarine, the USS Miami has 4 x 21 in (533 mm) torpedo tubes in the bow that can fire up to 37 Mk 48 series torpedoes. She can also use Tomahawk cruise missiles against land targets and Harpoon anti-ship missiles against surface warships.

Like other submarines of this type, she can also be used to lay mines.

Externally, the ship has a typical American submarine shape with a rounded nose cone and a tapered stern wrapped around a single propeller shaft. The sails are set near the midship and contain the necessary communications and optical systems consistent with modern submarine designs.

Sensor and processing systems include the BQQ-5, which includes a sonar system, ESM receiver, WLR-9 acoustic receiver, BRD-7 radio direction finder and BPS-15 radar system. She also deployed the WLR-10 countermeasure kit for self-defense.

The USS Miami has been in service for about 20 years and has been commissioned to the Portsmouth Naval Shipyard in Kittery, Maine for a scheduled overhaul. She arrived there on March 1, 2012. As work on the ship progressed, civil contractor Casey Fury caught fire on May 23, severely damaging the ship's interior. Several people were injured in the ensuing blaze, which took about twelve hours to put out.

Fury was sentenced to 17 years in federal prison and a $400 million fine. While high-level talks and lobbying got the ship repaired and put back into service, budget cuts prompted the Navy to retire the ship.

The USS Miami was subsequently decommissioned and is scheduled to be scrapped after its critical systems have been removed.

The USS Miami joins more than 20 decommissioned Los Angeles-class submarines. The Seawolf class officially succeeded the class and entered service in 1997. Of the 29 originally planned, only 3 were completed (all 26 were cancelled).

This has resulted in the Virginia class, of which 30 are now planned and 10 have been completed.
