The Swedish Defence Materiel Administration (FMV) has awarded a contract to Saab to deliver new sensor systems for the Royal Swedish Navy's two A26-type and two Gotland-class submarines.
The latest $55.8m order forms part of the letter of intent (LOI) signed on 9 June, covering Sweden's underwater capabilities, and refers to the 2015 to 2024 period.
However, neither a production order for A26-type submarines nor a modification order for Gotland-class vessels are included.
The deliveries, which are set to take lengthy lead-times, have been ordered in a timely approach to enable the FMV to proceed with its plans for the A26 next-generation submarine programme.
The new submarine sensor systems detect threats and identify other submarines and surface vessels, while providing navigation support.
In July, Saab received a $70m order from the FMV for the construction of the next-generation A26 submarines, in addition to mid-life updates to two Gotland-class submarines, as well as systems design and detailed construction.
A further LOI was signed by both parties regarding the work that will be offered to the Swedish Government for the development, design and production of submarines and other underwater systems.
Saab's selection follows the cancellation of Sweden's deal with ThyssenKrupp for the construction of new models and upgrades to some of its existing underwater fleet.
