Acceptance Trial

The future USS Mobile (LCS-26) successfully concluded its acceptance trial in the Gulf of Mexico September 25 after a series of in-port and underway demonstrations.

Future USS Mobile (LCS-26) Completes Successful Acceptance Trial

The Navy conducted comprehensive tests of the Independence-variant littoral combat ship’s systems during the trial, spanning multiple functional areas including main propulsion, auxiliaries and electrical systems. USS Mobile (LCS-26) also performed a full-power demonstration, steering and quick reversal, anchor drop test and combat system detect-to-engage sequence. The acceptance trial is the last significant milestone before delivery of the ship to the U.S. Navy, currently planned for October.

«I am impressed with the outstanding results achieved by the U.S. Navy and industry team during this acceptance trial of the future USS Mobile. We continue to see impressive results during trials as we work to provide warfighting capability to the fleet and the nation», said Captain Mike Taylor, Littoral Combat Ship program manager.

Following delivery and commissioning, Mobile will sail to its homeport in San Diego with sister ships USS Independence (LCS-2), USS Coronado (LCS-4), USS Jackson (LCS-6), USS Montgomery (LCS-8), USS Gabrielle Giffords (LCS-10), USS Omaha (LCS-12), USS Manchester (LCS-14), USS Tulsa (LCS-16), USS Charleston (LCS-18), USS Cincinnati (LCS-20), USS Kansas City (LCS-22), and USS Oakland (LCS-24).

Four additional Independence-variant ships are under construction at Austal USA in Mobile. Final assembly is well under way on USS Savannah (LCS-28). The modules for USS Canberra (LCS-30) are erected. Additionally, Austal is fabricating modules for USS Santa Barbara (LCS-32) and fabrication has started on USS Augusta (LCS-34). USS Kingsville (LCS-36) and USS Pierre (LCS-38) will begin fabrication in 2021.

Littoral Combat Ship (LCS) is a highly maneuverable, lethal and adaptable ship designed to support focused mine countermeasures, anti-submarine and surface warfare missions. The Independence-variant LCS integrates new technology and capability to affordably support current and future missions, from deep water to the littorals.

LCS is now the second-largest surface ship class in production, behind the Navy’s DDG-51 Arleigh Burke-class destroyer program. In 2019, three LCSs were delivered to the fleet and four will be delivered in 2020 – a shipbuilding pace not seen since the 1990s.
