Last of the U-Boots

[CCIP]

As per U-boat.net

U-995 (VIIC), which is now on display at Laboe, served as the Norwegian "Kaura" until 1965.

U-2540 (XXI), now on display at Wesermunde, served as research vessel "Wilhelm Bauer" and used for testing new models of German torpedoes in the 60's and 70's, and was transferred to the museum in 1984.

And I don't think it's true that morale would've been low - it's peace time. I remember visiting the Soviet submarine D2, which was built in the late 20's, fought in WWII and used for training until the 80's, and the retired diesel boat captain who lead the tour - while not having much to say for the comforts - spoke very fondly about the boat. I'm sure the VIIs weren't used as combat-ready boats, either - training most likely.

Some U-boats are still on service (of cause not Navy, but other stuffs)

U-550 become a museum boat, where she has the service there

A Type XXI (U-2540?) became a research boat


Romeo and Whiskey class submarine, which is derivated from the Type XXI boat, remained service in North Korea. China also got some, but put it in a reserve position (in case of a war)
