Sagem to equip four Swedish Navy's submarines with Series 30 optronic masts

The contract provides for Sagem Series 30 optronic surveillance masts to outfit two future A26 class submarines and two Gotland class submarines, already in service, along with initial logistic services and options for additional systems.

Saab Kockums' selection of Sagem's optronic mast was based on its high-performance optronic sensors, easy integration in the ship's combat system, and a human-machine interface that allows for optimized operation of its high-definition imaging functions.

Using modern non-penetrating technology for the subs' pressure hulls, Sagem's optronic masts feature a compact design and highly integrated multi-sensor architecture. They meet the Swedish navy's most demanding stealthiness requirements. They are compatible with a full range of electromagnetic antenna (GPS, ESM, early warning and communication), it includes a high-definition thermal imager as well as a high-definition camera, and can simultaneously accommodate a low-light level, anti-blooming camera and a laser range finder.

Series 30 masts' four optronic sensors, which can be used simultaneously to obtain panoramic scene captures in record time, are the fastest on the market. Known as the “Quick Look Round” feature, it enables panoramic or segment displays in separate, full resolution or compressed windows. This mode is available in addition to the conventional, live display of the different video channels.

The optronic surveillance masts to be delivered to the Swedish navy are based on Sagem's Series 30 family, already produced for the Scorpène class submarines built by French shipyard DCNS for the international market, and the future Suffren class nuclear attack submarines for the French navy (Barracuda program). Sagem's optronic masts were ordered by the South Korean shipyard DSME in 2014 for its KSS-III ocean-going submarines.
