Plymouth-based MSubs Ltd has been awarded a contract by the UK Royal Navy for a large autonomous underwater vehicle, First Sea Lord Admiral Tony Radakin revealed at the Underwater Defence and Security Conference.

The Royal Navy has awarded a contract for a large autonomous underwater vehicle, First Sea Lord Admiral Tony Radakin revealed at the Underwater Defence and Security Conference.

According to the contract, MSubs will provide the senior service with a 30-metre unmanned underwater vehicle (UUV), which has a range of up to 3,000 nautical miles.

“I am really excited by the possibilities that this offers to increase our reach and lethality, improve our efficiency and reduce the number of people we have to put in harm’s way,” said Adm Radakin.

MSubs has earlier revealed its Moray Extra Large Unmanned Undersea Vehicle (XLUUV) with a length of around 25 meter. According to the company, MORAY is a multi-role XLUUV system designed for sea-denial and maritime domain awareness operations.

Modular in design, the UUV can be configured for specific Anti-Submarine Warfare (ASW); Anti-Surface Warfare (ASuW); Mine Countermeasures (MCM); Intelligence, Surveillance and Reconnaissance (ISR) offensive and defensive roles in all threat environments.

MSubs claims that MORAY draws on proven in-service technologies to deliver a versatile force multiplier at a fraction of the cost of a manned system.

The UUV is designed to act independently and as a fully networked sensor capable of automatically queuing manned and unmanned sensors to assist in the localisation and prosecution of Contacts of Interest (COIs). COIs include surface and subsurface vessels (including AUVs), mine-like objects and specific emissions on the EM spectrum. In addition to a wide range of primary roles, MORAY’s modular design lends itself to many secondary functions such as covert insertion of SF payloads, underwater logistics hub/command and control (C2) node for AUVs, theatre level OPDEC (Operational Deception) platform and advanced ASW trainer.
