The first of the UK Royal Navy’s (RN's) Astute class submarines has begun to have its communications systems upgraded with SEA’s Network Interface Unit (NIU), company bosses have revealed.
Speaking to Shephard, officials said work had started on 9 September with the ‘integration of radios and fit’. They added that work would continue for the next year or so.
The upgrade will see the replacement of the telephone patch panel with a flexible and reconfigurable architecture, which SEA said, would provide size, weight and power benefits for the submarine. It will also allow communications operators to manage and control information from any part of the submarine. The project will incorporate Aurora, Astute’s External Communications System.
More specifically, the upgrade will see the interconnection of analogue and digital information, transfer to a LAN/WAN system as well as connectivity to legacy equipment.
The integration comes on the back of a £10m contract awarded to SEA by the UK’s MoD in 2003. SEA is understood to have beaten Babcock and Lockheed Martin to a £13m integration contract some 18 months ago.
SEA executives told Shephard that Astute boats 5, 6 and 7 could also be retro-fitted with the upgrad although they were unable to comment on when this may happen.
SEA communications systems director Seamus Brogan, said: ‘Communications systems have traditionally evolved by adding or replacing independently developed stove-piped sub-systems, resulting in an incoherent overall system architecture which consists of a muddle of incompatible systems.
‘NIU is designed to overcome this problem. Openness and standardisation are key features and the use of networks at the heart of the infrastructure enables centralised control and management and allows a flexible office layout,’ he said.
Looking abroad, SEA added that it had entered a bid for an Australian upgrade programme for surface warships, adding that they had also received interest in upgrading ‘other C2 systems’.
‘But for submarines, this programme is more pressing due to SWAP issues,’ Brogan said. NIU is already operated on RN Swiftsure and Trafalgar-class submarines.
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
The Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) counter-improvised explosive device (C-IED) and Drone Restricted Access Using Known Electromagnetic Warfare (DRAKE) counter-UAS (CUAS) systems are mounted and dismounted RF jammers.
Adarga’s Vantage information analysis tool is in service with the UK MoD and individual UK forces. It builds on the company’s Knowledge Platform which processes, organises and analyses open source material, as well as information held by the user’s military, security and intelligence services.
