MacArtney Underwater Technology has been contracted to supply SubConn underwater connectivity solutions to the French, Italian and Moroccan navies, for use in their frégate européen multi-mission (FREMM) frigates.

The company has designed the connectivity solutions in collaboration with naval defence technology contractors, Thales and WASS.

Under the contract MacArtney will provide the 'inboard' lead-in cables running from the sonar dome to a central hub within the hull of the ship.

The company will also supply SubConn underwater connectivity harnesses, which will provide the power and signal interface for all sonar elements within the sonar dome.

The Subconn harness cables each feature five power and signal outlets for plugging into sonar elements, as well as one SubConn connector, which connects to the inboard system.

"MacArtney will provide the 'inboard' lead-in cables running from the sonar dome to a central hub within the hull of the ship."

A total of 96 outboard harness cables have already been delivered to the French, Italian and Moroccan navies.

The contract is part of programme, run European joint armaments cooperation organisation, which aims to upgrade FREMM vessels designed by DCNS and Orizzonte Sistemi Navali.

As part of the programme, Thales previously installed an upgraded sonar suite in FREMM vessels, to increase the vessels anti-submarine detection ranges and torpedo defence capabilities.

The suite is a combination of the UMS 4110 CL bow mounted sonar and the towed CAPTAS 4 variable depth sonar.

The bow mounted sonar systems play a crucial role in enhancing the undersea threat detection and response capability of the FREMM frigates.
