GROTON, Conn. (Feb. 10, 2022) Students from the Machinist's Mate Submarines Auxiliary "A" school at the Naval Submarine School in Groton, Conn., conduct a training module using a newly installed 8 station, 3 Dimensional Multipurpose Reconfigurable Training System (MRTS 3D) on February 10, 2022. The MRTS 3D provides photo-realistic, virtual training on a variety of different systems used aboard submarines. MRTS 3D trainers are used in both Sailor pipeline courses and in pre-deployment team training. After the instructor sets up a training scenario, faults can be inserted at any stage. The student follows shipboard procedures, interacting with the simulation through multi-touch LCD monitors. The MRTS 3D can be configured to emulate the shipboard environment on any of the currently in-service Submarine classes in the U.S. Navy. Utilization of MRTS 3D training replicates the real-world operating environment and tasks required of Sailors aboard a submarine, and allows Sailors to gain hands-on familiarity with both the layout of systems on submarines and the procedures needed to operate them.
