Austal has been issued a $14m worth of contract modifications by the US Department of Defence (Dod) to a previously existing $3.5bn contract for littoral combat ships (LCS) for the US Navy.

Under the contract, the company will plan and implement the design changes, which were determined during the course of the construction of the vessel.

The rectifications and the modification on the design are necessary to support the sail-away and follow-on post-delivery test and trial period.

“Work on the contract will be undertaken at Austal’s shipyard in Mobile, Alabama.”

The cost-plus contract modifications also encompass options to provide support following the delivery of the USS Gabrielle Giffords (LCS 10) and USS Omaha (LCS 12).

Work on the contract will be undertaken at Austal’s shipyard in Mobile, Alabama, and the activities related to the contract will be monitored by the US Naval Sea Systems Command, Washington DC.

Austal was previously awarded a $1.6bn block-buy contract from the US Navy to construct ten expeditionary fast transport vessels (EPF).

The USS Gabrielle Giffords (LCS 10) is a 419ft-long, high-speed, highly manoeuvrable combat ship with a full-load displacement of 3,000t, a waterline beam of 103ft, and a cruising speed of 40k.

The ship is designed to combat littoral threats and secure the maritime security and sovereignty of the coastal waters, as well as executing the DoD’s strategy.

The USS Omaha is an aluminium trimaran ship and ranks fourth in the series built under the block-buy contract with Austal.

The company is currently constructing seven LCSs and three EPFs at its facility in Mobile, Alabama.
