The Virginia-class nuclear submarine USS Delaware (SSN-791) conducted a number of tests last week involving the launch of the REMUS medium unmanned underwater vehicle (UUV), according to Navy News on December 13.
During the operation, called "Yellow Moray", the unmanned underwater vehicle was launched from the torpedo tubes of the USS Delaware and in the same way**.
The "Yellow Sea Eel" system will provide additional mission capabilities for the U.S. submarine force and enhance the ability of U.S. Navy submarines to provide our country's global unified combat command.
The most recent tests marked the second of their kind and involved the launch of a submarine in this way and ** an unmanned underwater vehicle. Similar tests were carried out last week by the Pacific submarine forces. The test involved an unmanned underwater vehicle produced by L3Harris.
These two successful tests paved the way for the US Navy to deploy torpedo tube launches and medium unmanned underwater vehicles next year.
One of such systems currently under development is the Razorback of the US Navy. The initial version of the UUV was based on the Remus 600 and could only be launched from a dry deck bunker, requiring a diver launch and **. The Navy is currently working on an industry team of Leidos and L3Harris working to address the challenges previously faced by the Razor Whales. The two companies are working together to launch a new version of the Razorwhale, which is easier to ** and launch through the use of torpedo tubes.
The new Razorback variant is on track to pass a Critical Design Review (CDR) this year.
In addition to developing the new Razorback model, HII is also developing a new cabin for the UUV, called the Shockproof and Fireproof Cap. In addition to facilitating the launch and ** of unmanned underwater vehicles, the new capsule will also bring new safety guarantees to submarine personnel.
Due to the dangers of lithium-ion batteries used in UUVs, there is always the possibility of high-energy** events. As a result, SafeCap can use a battery** detection system to monitor the health of the battery on the UUV and contain and stop high-energy events in the event of an event.
It is known that to date, the submarine fleet of the Royal Swedish Navy is the only service in the world that has an operating system capable of ** torpedo-type UUV (and can carry them back inside the submarine through torpedo tubes). Since 2019, the Swedes have been using a system designed by Saab, called Subrov.
