The US Navy has selected Northrop Grumman's voyage management system (VMS), version 9.3, for installation onboard SSN and SSGN nuclear powered submarines.

The VMS version 9.3, which supports polar operations, has increased rendering speeds, and integrates seamlessly with combat radar and mission planning submarine systems. It also enables real-time checking of installed charts.

Programme executive office, submarines (PEO SUB), PMS 425 captain John D Zimmerman said: "VMS 9.3 brings significant performance and usability improvements over earlier versions and I appreciate the hard work by Northrop Grumman to make this a great product.

"Submarine Force feedback on VMS 9.3 has been very positive and the boats are excited to have it installed."

As a result of this new development, the VMS software package will be equipped on 55 SSNs and four SSGNs that are operating globally from all navy submarine homeports.

"Submarine Force feedback on VMS 9.3 has been very positive and the boats are excited to have it installed."

The navy has already started the installation of VMS on its submarines. Work is expected to be completed by the end of 2016.

Northrop Grumman maritime systems vice-president Todd Leavitt said: "These improvements in the VMS, along with a newly streamlined user interface, will help to dramatically improve the sailor's ability to navigate efficiently."

In April this year, Northrop Grumman's Sperry Marine business unit secured a contract to design and supply gyrocompass navigation systems for 12 Kingston-class coastal defence vessels for the Royal Canadian Navy.

The contract will comprise dual Navigat X MK1 gyrocompass systems, Navitwin IV heading management systems and a complete suite of heading repeaters.
