The Navy has identified two sailors who perished during routine diving operations at a test pond at an Army site in Maryland.

Navy Diver 1st Class James Reyher of Caldwell, Ohio, and Navy Diver 2nd Class Ryan Harris of Gladstone, Missouri, died Tuesday at the Aberdeen Proving Ground in northeastern Maryland.

The sailors died during operations at Aberdeen’s Underwater Test Facility, dubbed “Super Pond.”

It is used to conduct shock testing of vessels, submarine systems and munitions.

Harris and Reyher were assigned to Mobile Diving and Salvage Unit 2 at Joint Expeditionary Base Little Creek-Fort Story in Virginia Beach, Virginia.

 

The incident is under investigation.
