NASSCO-Awarded--1-4-Billion-to-Build-Additional-Navy-Ships

General Dynamics National Steel and Shipbuilding Corporation (NASSCO) has received $1.4 billion in US Navy contract modifications for construction of a sixth Expeditionary Sea Base ship (ESB 8) and two additional John Lewis-class fleet oilers (T-AO 211 and 212). 

This award comes in addition to $600 million already received to procure long-lead time materials for the same ships. Construction is scheduled to begin in the third quarter of 2023 and continue into 2027.

The contract modification also provides an option for the Navy to procure an additional oiler, T-AO 213, bringing the total potential value to $2.7 billion for the four ships.

In 2011, the Navy awarded NASSCO with a contract to design and build the first two ships in the newly created Mobile Landing Platform program, USNS Montford Point and USNS John Glenn. 

The program evolved, adding USS Lewis B. Puller (ESB 3), USS Hershel “Woody” Williams (ESB 4), USS Miguel Keith (ESB 5), the future USS John L. Canley (ESB 6) and the future USS Robert E. Simanek (ESB 7). ESB 6 and ESB 7 are currently under construction.

ESB ships are highly flexible platforms designed to support multiple maritime-based missions, including Air Mine Counter Measures, Special Operations Forces, and limited crisis response. Acting as a mobile sea base, this 784-foot ship has a 52,000 square-foot flight deck to support MH-53, MH-60, MV-22 tilt-rotor, and H1 aircraft operations.  

In 2016, the Navy awarded NASSCO with a contract to design and build the first six ships in the next generation of fleet oilers, the John Lewis-class. Designed to transfer fuel to US Navy ships operating at sea, the 742-feet vessels have a full load displacement of 49,850 tons, capacity to carry 157,000 barrels of oil and significant amounts of dry cargo, as well as providing aviation capability while traveling at speeds up to 20 knots.

The first ship, USNS John Lewis (T-AO 205), was delivered to the US Navy in July 2022. The USNS Harvey Milk (T-AO 206), USNS Earl Warren (T-AO 207), and USNS Robert F. Kennedy (T-AO 208) are currently under construction.

“NASSCO is committed to working together with the Navy to deliver these much needed ships to the fleet,” said Dave Carver, President of General Dynamics NASSCO. “As partners with the Navy, we remain dedicated to ensuring the success of both of these programs to help enhance and expand the Navy’s forward presence and warfighting capabilities while providing sustained growth for our workforce.”
