The Greyback submarines were built in the 1950s for the United States Navy and the U.S. Navy Pacific Command.
The submarines were decommissioned in 1983 and never saw action in the 21st century.
They were retired after the end of the Cold War but were then sent to the Pacific for testing.
A number of grayback submarines have been spotted since then, and a Greyback sub has been detected off the coast of Chile.
But it has never been seen again.
That’s about to change.
Submarines will now be able to use the Greyback’s sonar to locate underwater objects and search for submarines, according to a new report.
[Washington Post] Greyback Submarine Tests Out of Service Grayback submarines are decommissioning and will be returning to the water in a new test.
According to the report, Greyback will be using the new system, which was first tested in 2011.
The Greyback system will include three sensors: a two-channel sonar and a sonar with three different wavelengths.
The sonar can detect objects that are 20 feet or less in depth, the report said.
Grayback said in a statement that the new sensor system was developed in response to the global submarine search efforts that are underway.
It will provide the Grayback with an enhanced understanding of the submarine environment and capabilities to better support search and rescue operations, the company said.
[Reddit] New Grayback Submarine To Be Deployed in the Pacific The U.K.-based Greyback subsidiary is now preparing to deploy a new submarine, according the report.
Greyback has previously deployed two Grayback submersibles and a new submersible in the Atlantic.
The new Grayback submarine is scheduled to be ready for testing in 2020.
“It is clear that the Graybears have been the most innovative and flexible submarine to deploy in the service of the United Kingdom,” Greyback said.
“We are proud of our innovative approach to delivering innovative products and services to the United Kiosks.”
Greybears Submersibles Deployed For Search and Rescue, Sea Shepherd and Maritime Patrol Submariners are deploying Graybases for search and recovery operations and marine patrol and maritime patrol missions.
[Pacific Times] Graybears Deploy Graybades for Search and Recovery in Atlantic Ocean The Greybears subs will be deployed in the U/S Sasebo Strait, near the Strait of Malacca, for search-and-rescue missions.
