The roots of all OTS communications gear begin from supplying the U.S. Navy, as well as other government agencies, with underwater communications. OTS gear is designed to meet special operator’s demands and is used by many Special Forces around the world. All systems cannot be shown. Many systems are custom designed—meeting tactical demands specific to the user’s needs.

OTS has many items currently on the Authorized for U.S. Military Use (AMU) List. Recently, the British Royal Navy went out to the world and asked for all underwater communication manufacturers to send equipment for a 1 year evaluation. The outcome for the winner was a $1.4 million dollar contract, and the British Royal Navy would standardize on the victor’s equipment. OTS was the victor—beating all other suppliers.

If you are looking for the finest, field-tested underwater communication system, OTS has the solution to your needs.
