In support of new operational priorities, there are future plans to equip the 212A with a land-attack capability. The Interactive Defense and Attack System for Submarines (IDAS), currently under development by Diehl BGT Defence, HDW and Kongsberg of Norway, uses a wire-guided missile to engage helicopters and mobile targets on shore. The third Type 212 submarine, U33 was selected as the platform for testing the new weapon. The missile made the first flight in June 2008, successfully launched from the torpedo tubes of the submerged submarine.
A total of five Joint Support Ships, two JSS800 and three JSS400, were planned during the 1995–2010 period but the programme appears now to have been abandoned, not having been mentioned in two recent defence reviews. The larger ships would have been tasked for strategic troop transport and amphibious operations, and were to displace 27,000 to 30,000 tons for 800 soldiers.  The German Navy will use the Joint Support Ship HNLMS Karel Doorman (A833) of the Royal Netherlands Navy as part of the integration of the German Navy Marines (Seebatallion) in the Royal Netherlands Marine Corps as of 2016.
Accomodation for 38 passengers.
Operated on the route between Europe and Straits/Bangkok.
Homeward bound on voyage no. 27, the vessel was lost in a fire, which broke
out in the engine room May 9th, 1939 about 20 nautical miles south of the
Barberyn Lighthouse on Ceylon. Passengers and crew went into the life boats
and were picked-up by Canton (P&O) and HMS Grashopper
(British Navy). The vessel drifted aground west of the city of Galle where
it burned completely out.
