Navy JROTC Cadets test dive submersibles

Student Cadets attending the Everett High School Navy Junior Reserve Officer Training Corps (JROTC) program just completed their introduction to naval engineering unit. For eight weeks, Naval Science 1 Cadets from Everett, Cascade and Jackson High schools studied naval mechanical, materials, electrical and project management engineering.

At the end of the unit, all 13 teams gathered around the Everett YMCA of Snohomish County pool to test their Remotely Operated Vehicles (ROV) in watery action–the most highly anticipated part of the study unit. With the help and support of the Naval Station Everett Fleet Diving Detachment, the Cadet’s ROVs operated well.

Gunnery Sergeant Dan Boudreau USMC (Retired), Naval Science Instructor described the poolside action, “Three blasts of a submarine diving claxon sounded, heralding the start of the operational test dives!” Cadets conducted function checks at the first station which gave each cadet in a SeaPerch crew a chance at the operational controls.

“In the second station, Cadets conducted drag races against another SeaPerch crew ROVs both on and below the surface to learn about the different operating characteristics of each ROV."

"At this point, during sustained operations at speed and ‘on step,’ three engineering casualties developed. One SeaPerch starboard engine failed while the other two engines kept functioning. This caused consternation and critical thinking among the crew! The two other casualties were from two separate SeaPerch ROVs, which each lost a propeller. Luckily, the Navy divers were able to salvage the propellers and lock nuts that had held the propellers in place, so those crews were able to resume and complete the operational test dives.”

More information and more photos of the dive tests and of the Cadets building the ROV are online.

Boudreau noted that the cadet learning experience is made possible by the SeaPerch Program which is sponsored by the Office of Naval Research (ONR) and managed by the Association of Unmanned Vehicle Systems International (AUVSI) Foundation. He also thanked the NJROTC Booster Club for their support for the activity, which included some funding.
