Top speed submerged surely must be more than 15 knots. That speed is akin to 50s era diesel-electrics. 20 knots plus is more realistic, as it is closely related to 20knot 212A and 214. I am sure many modern diesel-electric (especially those with Lithium Ion batteries) are capable of mid-high 20s in terms of speed, but when that information will be de-classified is anyone's guess. I see no design reasons why the top speed of this class is so slow compared to its contemporaries (especially given similar hull / power numbers). 142.78.8.4 ( talk) 16:26, 21 December 2023 (UTC) reply
