Future expeditionary fast transport USNS Yuma (T-EPF-8) successfully completed acceptance trials January 26, 2017 after two days of underway evaluation in the Gulf of Mexico. USNS Yuma (T-EPF-8) completes acceptance trials The ship returned to the Austal USA shipyard after demonstrating the readiness of its equipment and system operations for the Navy’s Board of Inspection and Survey. By conducting numerous tests, both dockside and underway, surveyors were able to evaluate and determine the ship met all criteria required for final acceptance. «The EPF program continues to be a successful model of serial ship production», said Captain Henry Stevens, Strategic and Theater Sealift program manager, Program Executive Office (PEO), Ships. «The class continues to grow and advance the U.S. Navy, expanding U.S. presence across the maritime theater. I look forward to seeing EPF-8 deliver this year and the continued success of the program». Expeditionary fast transports are versatile, noncombatant vessels designed to operate in shallow-draft ports and waterways. They provide increased operational flexibility for a wide range of activities including maneuver and sustainment, relief operations in small or damaged ports, flexible logistics support, or as the key enabler for rapid transport. They are capable of interfacing with roll-on/roll-off discharge facilities, as well as on-loading/off-loading vehicles such as a fully combat-loaded Abrams main battle tank. Each vessel includes a flight deck to support day and night aircraft launch and recovery operations. Yuma will have airline-style seating for 312 embarked forces with fixed berthing for 104. As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and special warfare craft.

Austal Limited is pleased to announce the christening of Expeditionary Fast Transport vessel USNS Yuma (T-EPF-8) at a ceremony held at Austal USA’s Mobile, Alabama shipyard on Saturday, 20th August 2016.
Ship sponsor Mrs. Janet Napolitano, former Governor of Arizona and current President of the University of California, joined distinguished guests from the U.S. Navy, State and Local Government, Austal USA management and employees for the christening ceremony, held beneath the hull of the ship in the final assembly bay.
USNS Yuma (T-EPF-8) is the eighth of 10 Expeditionary Fast Transport vessels (EPF) that Austal USA is delivering under a contract with the U.S. Navy valued in excess of US$1.6 billion.
«On behalf of Austal USA’s shipbuilding team – one of the most talented that I’ve ever worked with – we are proud to provide our Navy with an incredible vessel that will honour the great city of Yuma as she supports humanitarian efforts the world over», said Austal USA President Craig Perciavalle. «The EPF program has matured very well and we are confident that the EPF fleet will continue to serve our Navy as a highly flexible platform», Mr. Perciavalle added.
EPF-8, a 337.9 feet/103 meter, shallow draft all-aluminium catamaran, is a multi-mission, non-combatant transport vessel characterized by its high volume, high speed, and flexibility. It is the fourth U.S. Navy ship to be named Yuma as a tribute to the residents of the Arizona city and their close ties with the military.
USNS Yuma (T-EPF-8) will ultimately join her sister EPF’s that have been delivered over the last three years, including USNS Spearhead (T-EPF-1) which has logged over 100,000 nautical miles/115,078 miles/185,200 km at sea and is currently on her fifth deployment since she was delivered in 2012.
Three more EPF’s and seven Independence variant Littoral Combat Ships (LCS) are currently under construction at Austal USA. Next month, the shipyard is scheduled to launch USNS Yuma (T-EPF-8), while the future USS Gabrielle Giffords (LCS-10) will undergo builder’s sea trials.

On March 29 in Mobile, Alabama Austal USA celebrated the keel-laying milestone for the Expeditionary Fast Transport (EFT) vessel USNS Yuma (T-EPF-8) with a ceremony marking a significant milestone in the ship’s construction. This ship is the eighth EPF built at Austal USA under the 10-ship, $1.6 billion block-buy contract awarded to Austal in 2008.
Mayor Nicholls was assisted by Austal USA A-Class welder, Courtney Cagle
Laying the keel is the formal recognition of the start of a ship’s construction. The keel runs lengthwise down the middle of the ship serving as the basic foundation or spine of the structure, providing the major source of the hull’s strength.
The Honorable Douglas Nicholls, Mayor of the City of Yuma, Arizona, authenticated the keel at the ceremony by welding his initials onto an aluminum keel plate that will eventually be placed in ship’s hull. Mayor Nicholls was assisted by Austal USA A-Class welder, Courtney Cagle. Ms. Cagle began her employment with Austal USA in 2012 as an apprentice.
«I am excited to reach this significant milestone today in such a short period of time, considering we just launched EPF-7 from this bay in late January», Austal USA President Craig Perciavalle said. «The momentum we’re experiencing on the construction of this amazing ship is evidence of the strength of Austal’s EPF program, and the continued success displayed by Austal’s talented shipbuilding team».
The EPF program at Austal is progressing rapidly. USNS Brunswick (T-EPF-6) was delivered in mid-January and there are three other EPFs under construction at Austal USA’s headquarters and ship manufacturing facility in Mobile, Alabama. Of the ships already delivered to the U.S. Navy, USNS Spearhead (T-EPF-1) is in Africa on its third deployment and recently took part in a successful anti-piracy operation. USNS Choctaw County (T-EPF-2) and USNS Millinocket (T-EPF-3) are also currently deployed supporting U.S. Navy fleet operations, including many international exercises.
Austal is also under a 10-ship block-buy contract worth over $3.5 billion for the U.S. Navy’s Independence-variant Littoral Combat Ship (LCS) program. The company has delivered three LCS with another seven currently under construction. The future USS Montgomery (LCS-8) is scheduled for delivery later this year.
Ships
Defence vessels designed and built by Austal include multi-mission combatants, such as the Littoral Combat Ship (LCS) for the United States Navy and military high speed vessels for transport and humanitarian relief, such as the Expeditionary Fast Transport (EPF) – previously known as the Joint High Speed Vessel (JHSV) – for the United States Navy and High Speed Support Vessel (HSSV) for the Royal Navy of Oman. Austal also designs, constructs, integrates and maintains an extensive range of patrol and auxiliary vessels for government agencies globally, including the Cape Class Patrol Boat Program for Australian Border Force. Defence vessels are designed and constructed in Mobile, Alabama and in Henderson, Western Australia.
Austal has been at the forefront of the high speed ferry market since the early days of the industry. Our market leading designs of high performance aluminium vessels have long been at the heart of Austal’s research and development. Today, commercial ship construction is centred on our shipyard in Balamban, Philippines.
