This is the second vessel delivered by Austal USA to the U.S. Navy this month.

Austal Chief Executive Officer (CEO) David Singleton said the delivery of the latest Expeditionary Fast Transport (EPF) is further evidence of Austal USA’s success in efficient, modern shipbuilding and expertise in modular manufacturing.

«Our hard working, highly skilled workforce continues to deliver on this important program, which is redefining naval capability and exceeding stakeholder expectations around the globe».

Three additional EPF remain under construction in Mobile as part of a 10-ship, US$1.6 billion block-buy contract from the U.S. Navy. The future USNS Yuma (EPF-8) will be christened later this summer and will launch soon after, while modules for the City of Bismarck (EPF-9) are under construction in Austal’s Module Manufacturing Facility (MMF). The first aluminium was cut for Burlington (EPF-10) earlier this month and module construction has begun in the MMF.
