The O 21 - 27 Class was a 1937 Dutch Navy design. They were 949tons on the surface (slightly lighter than the German type IX), had eight torpedo tubes and carried 14 torpedoes. Range was about 7100 nautical miles on the surface at 10 knots. They had a crew of about 44 men. All of the boats were fitted with a Schnorchel, years before the Germans implemented it.

3 of those boats (U-D3, U-D4 and U-D5) fell into German hands in May 1940.
