The US Navy’s newest expeditionary fast transport (EPF) vessel, the future USNS Carson City (EPF 7), has completed acceptance trials during an underway period in the Gulf of Mexico.

During the trials, the navy’s Board of Inspection and Survey (INSURV) remained on-board the vessel to examine and evaluate the ship’s performance.

The trial included a range of tests that were conducted both dockside and underway in order to evaluate the operational readiness of the vessel prior to its delivery to the US Navy.

"Acceptance trials is a major step towards delivering Carson City to the navy."

The vessel is made to undergo such thorough testing to ensure the delivery of a functional, safe and capable naval vessel.

Program Executive Office strategic and theatre sealift programme manager captain Henry Stevens said: "Acceptance trials is a major step towards delivering Carson City to the navy.

"The ship performed very well at acceptance trials, which is a great reflection of the hard work of our contractor and government team’s commitment to delivering quality ships."

The future USNS Carson city is the seventh of the ten EPFs, formerly known as joint high-speed vessels (JHSV), being built by Austal under a $1.6bn US Navy block-buy contract.

The 338ft-long shallow draft aluminium catamaran vessel is a non-combatant vessel, which is designed to deliver high volume, speed and flexibility in its operation.

It can be deployed to engage in a range of missions such as manoeuvring and sustainment, relief operations in small or damaged ports, and logistics support for quick transport.

USS Carson City is outfitted with a flight deck to support day and night aircraft launch and recovery operations and features an airline-style seating for 312 embarked forces with fixed berthing for 104.
