Military Sealift Command Ships Exercise Seabasing Capabilities During Pacific Horizon 2017

Off the coast of Southern California’s Camp Pendleton, two Military Sealift Command ships are currently supporting the Marine Corps crisis response exercise, Pacific Horizon 2017, while simultaneously testing the Seabasing capabilities of both ships.

At anchor, off-shore, expeditionary transfer dock ship USNS John Glenn (T-ESD 2) and large, medium-speed roll-on/roll-off ship USNS Dahl (T-AKR-312) are conducting ship-ship operations, that position the ships feet apart. Using a ramp that extends from Dahl to Glenn, Marine Corps rolling equipment such as M88 Armored Recovery Vehicles (ARV) and Internally Transportable Vehicle-Light Strike Vehicles (ITV-LSV) is transferred to Glenn which serves as a mobile supply and vehicle depot used to ferry materials by Landing Craft, Air Cushions (LCACs) to the beach.  The LCACs travel back and forth from the ships to the beach carrying vehicles and supplies in support of simulated humanitarian assistance and disaster relief operations being held ashore.

Rolling Marine Corps equipment is transferred from the Military Sealift Command’s large, medium-speed roll-on/roll-off ship USNS Dahl (T-AKR-312) to the Military Sealift Command expeditionary transfer dock ship USNS John Glenn (T-ESD 2). Both ships are supporting the Pacific Horizon 2017 exercise off the coast of Camp Pendleton in Southern California.

In addition to the vehicle transfers, Glenn and Dahl conducted the first, at-sea crane transfer of cargo from a RO/RO to an ESD while performing ship-ship operations.  The crane transfer demonstrates another aspect of the flexible platform the EDS provides in support of the Navy’s Seabasing concept, which enables large-scale logistics movements from sea to shore and prepositioned Marine Corps equipment from the Sea Base to the shore.

The operation the first, at-sea crane transfer of cargo from a RO/RO to an ESD while performing ship-ship operations.

“Participating in an exercise like Pacific Horizon provides the crews of both the RO/RO and the EDS with critical training in ship handling, line handling and VTR movements which are required for providing SeaBasing support to the Marines,” said Capt. William McCullough, Glenn’s contracted civilian master.  “This is a great, hands-on experience for my crew!”

Pacific Horizon 2017 continues through July 20.
