Acceptance Trials

The future USNS Apalachicola (T-EPF-13), the U.S. Navy’s 13th Spearhead-class expeditionary fast transport successfully completed Acceptance Trials and Unmanned Logistics Prototype Trials.

Acceptance Trials consists of a series of in-port and at-sea demonstrations that allow the U.S. Navy and the shipbuilder, Austal USA, to assess the ship’s systems and readiness prior to delivery to the Navy.

«The completion of this milestone is another win for our Navy and industry partners and a testament to the hard work of our shipbuilding team», said Tim Roberts, program manager, Strategic & Theater Sealift, Program Executive Office (PEO) Ships. «USNS Apalachicola (T-EPF-13) will enhance the operational flexibility needed by our Sailors».

USNS Apalachicola (T-EPF-13) also completed Unmanned Logistics Prototype trials assessing autonomous capabilities integrated into the shipboard configuration, demonstrating that a large ship can become a self-driving platform.

In transit from Mobile, Alabama, to Miami, Florida, Apalachicola’s autonomous system completed a stress test in high-traffic coastal areas by taking appropriate ship handling actions while operating around other ships, boats, sailboats, and craft. Overall, the ship was in autonomous mode for approximately 85 percent of the multiple day at-sea period.

The unprecedented development of autonomous capability on Apalachicola is the culmination of collaborative efforts with the Navy’s shipbuilding and industry partners, Austal USA, L3 Harris and General Dynamics.

«The ability to expand unmanned concepts into the existing fleet was validated by these trials», said Roberts. «The capabilities integrated onto EPF 13 set the groundwork for future autonomous operations».

EPFs are shallow draft, commercial-based, catamaran designed for rapid, intra-theater transport of personnel and equipment. The EPF’s high speed, shallow draft, and ability to load/unload in austere ports enables maneuver force agility in achieving positional advantage over intermediate distances without reliance on shore-based infrastructure.

USNS Apalachicola (T-EPF-13) is scheduled to be delivered to the U.S. Navy later this year.

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, boats and craft.

Autonomous capabilities

The future USNS Apalachicola (T-EPF-13) is performing a series of planned test events assessing autonomous capabilities integrated into the shipboard configuration, demonstrating that a large ship can become a self-driving platform.

Known as Unmanned Logistics Prototype trials, each test event increases the perception capabilities and complexity of behaviors demonstrated by the autonomous systems. Test evolutions to date include point-to-point autonomous navigation, vessel handling and transfer of vessel control between manned to unmanned modes.

«The autonomous capabilities being demonstrated by this prototype system represent a major technological advancement for the EPF platform, the U.S. Navy at large and our industry partners. EPF-13 will be the first fully operational U.S. naval ship to possess autonomous capability including the ability to operate autonomously in a commercial vessel traffic lane», said Tim Roberts, Strategic and Theater Sealift program manager, Program Executive Office (PEO) Ships. «This testing is a game changer and highlights that there is potential to expand unmanned concepts into existing fleet assets».

Collaboration for the test events include team members from PEO Ships, PEO Unmanned and Small Combatants, Naval Systems Engineering and Logistics Directorate – Surface Ship Design and System Engineering, Supervisor of Shipbuilding – Gulf Coast, Naval Surface Warfare Center support from Carderock, Combatant Craft Division, Dahlgren and Philadelphia and the Navy’s shipbuilding and industry partners, Austal USA, L3 Harris and General Dynamics.

Future test events will add levels of difficulty and include night navigation, and differing weather and sea states. These trials will set crucial groundwork for autonomous vessel operations, to include vessel encounter and avoidance maneuvering and compliance with International Regulations for Preventing Collisions at Sea.
