OSI Maritime Systems has been subcontracted by Saab to deliver its tactical dived navigation systems (TDNS) for the Royal Swedish Navy's two new A26 submarines.

Under the contract, OSI will design, construct, integrate and set to work a TDNS system for each submarine.

Developed specifically for use on subsurface platforms, OSI's TDNS features a bespoke hardware design and the full operational capability offered by the company's ECPINS submarine.

"The new A26, which is claimed to be the world's most modern submarine programme, will be capable of operating in all oceans."

OSI's ECPINS has been independently certified against Nato WECDIS STANAG 4564. TDNS will also be closely interfaced with other submarines' systems and sensors.

The company's navigation solutions are also deployed with the navies of the UK, Australia, Canada, Netherlands, South Africa, Portugal, Brazil, and Sweden.

The new A26, which is claimed to be the world's most modern submarine programme, will be capable of operating in all oceans and across a broad spectrum of conflict environments.

The vessel is equipped with a multi-mission portal to be able to launch and retrieve diverse mission payloads, such as manned and unmanned vehicles.

Powered by conventional diesel-electric propulsion machinery, A26 will also feature the Kockums Stirlingair-independent propulsion (AIP) system, which allows the submarine to be stealthy and difficult to detect.

In June, Saab signed contracts worth Skr7.6bn ($919.01m) with the Swedish Defence Materiel Administration to deliver two new Type A26 submarines.

Saab has already started construction work on the next-generation submarines, with delivery expected to commence in 2022, and to be complete in 2024.
