HMS Hajen (1904)

3D Model

Hajen (Shark), launched in 1904, was the first submarine constructed for the Swedish Navy. She was designed by Carl Richson, who had experience from US shipyards and was influenced by the work of submarine pioneer J P Holland. Hajen had an electric propeller which received power from a combustion engine when surfaced and from a battery when submerged. The vessel was in service until 1922 and is today an exhibit at the Naval Museum in Karlskrona. Original model by Hugo Åkerlund, 1924. 3D model by Adam de Kaminski for SMTM, 2023.

Hajen var svenska flottans första ubåt och sjösattes 1904. Hon konstruerades av Carl Richson, som hade arbetat vid amerikanska varv och hämtat idéer från ubåtspionjären J P Holland. Den eldrivna propellern fick sin kraft av en förbränningsmotor i ytläge. I undervattensläge användes batteridrift. Hajen var i tjänst till 1922 och visas idag på Marinmuseum i Karlskrona. Originalmodell byggd av Hugo Åkerlund 1924. 3D-modell producerad av Adam de Kaminski för SMTM 2023.
