About this program
The LOS ANGELES Class Nuclear Attack Submarine (SSN 688) is a Major Defense Acquisition Program (MDAP) under Major Capability Acquisition (MCA) pathway management. This program encompasses the acquisition and sustainment of the Navy's Los Angeles-class nuclear-powered fast attack submarines, which form a significant component of the U.S. submarine force. The program supports maintenance, modernization, and logistics activities necessary to maintain operational readiness of these naval vessels.
Contract awards associated with the program range from small-scale maintenance tasks valued at a few thousand dollars to major overhaul projects exceeding $90 million. Typical services include propeller repairs, ventilation system maintenance, tank cleaning, nuclear regional maintenance support, and various engineering support services. Contract durations typically span from immediate delivery to three-year performance periods. The Department of the Navy is the primary contracting authority, with work frequently performed at naval shipyards including Pearl Harbor Naval Shipyard and Norfolk Naval Shipyard. While most contracts are awarded without set-aside designations, some smaller maintenance tasks utilize Total Small Business or Service-Disabled Veteran-Owned Small Business set-asides. Notable contractors include Imia, LLC for submarine maintenance and painting services, Kropp Environmental Contractors for tank cleaning, and Amee Bay, LLC for equipment refurbishment. Contract types are predominantly firm-fixed-price, with some cost-plus-fixed-fee arrangements for more complex engineering and maintenance work.
