Submarines.
The submarine flotilla is planned to be replaced/updated with four new submarines in around 2030. Norway has joined forces with Germany to develop the new submarines based upon the German 212-class of submarines.
Surface combatants.
Frigate HNoMS Helge Ingstad sunk in a fjord outside of Bergen, Norway and has been decommissioned in 2019.
Auxiliary ships.
It was decided that due to delays on HNoMS Maud the two former inner coast guard vessels NoCGV Olav Tryggvason and NoCGV Magnus Lagabøte (both from the Reine-Class), would be transferred to the navy as auxiliary vessels.
