Eirik Raude Class

The Uppsala class is a class of 8 "conventional" (non-nuclear) propulsion attack submarines in service in the Kongelige Sjøforsvaret. Because of the innovative nature of their propulsion system and the quality of their control and armament systems, it is a class of attack submarines that surpasses in performance any submarine of non-nuclear propulsion and many of nuclear one.

Power generation & propulsion
The Eiri Raude Class submarine’s main nuclear powered propulsion system is based on the second-generation ASEA PWR2M, which was developed specifically for the Eiri Raude Class. Current generations of PWR allow submarines to circumnavigate the world about 20 times, whereas the latest development of PWR would allow circumnavigation 40 times without refuelling.

The other main items of machinery are two ASEA geared steam turbines, and a single shaft with a NAtech marine Pump-jet propulsor. There are two SCANIA diesel alternators, and two turbo generators from ASEA. The propulsion system provides a maximum submerged speed over 25kt.

Electronic systems
One of the main design premises was the need to mount Kalmar Union made electronic systems in order to full integration with other Forsvaret systems and satellite net.
