General Dynamics Receives $7.7 Million to Operate Floating Dry Dock Shippingport (ARDM-4)

General Dynamics Electric Boat (GDEB) is awarded a contract modification, worth $7.7 million, for the operation, maintenance and protection of the floating dry dock Shippingport (ARDM-4).

Fiscal 2020 operation and maintenance (Navy) funding in the amount of $1.9 million will be obligated at time of award and will expire at the end of the current fiscal year. The Naval Sea Systems Command (NAVSEA), Washington, DC, is the contracting activity.

The work will be performed in Groton, Connecticut, and is expected to be completed by November 2020.

Shippingport (ARDM-4) is a government-owned, contractor-operated ARDM-4-class U.S. Navy Medium Auxiliary Repair Dry Dock used to execute submarine repairs.

Laid down in 1977, delivered and placed in service on 4 January 1979, she is still in service at the Naval Submarine Support Facility (NSSF) at Naval Submarine Base New London in Groton, Conn.

With a displacement of 5400 tons, this floating dry dock had a lifting capacity of 7800 tons. It has two 25 ton portal gantry cranes on tracks, one running along the top deck of each hull side superstructure.
