For surface craft, I think boats used to infiltrate commandos, and agents used in by the US/ARVN in the Vietnam war and North Korea would somewhat qualify. I think they use wooden or fiber-lass hulls to reduce surface radar signatures. Whether anyone has tried to arm them with anything substantial, I don't know but it should not be that hard to if we can get a good fire-n-forget autonomous missile or torpedo. I'm not so sure how good passive sonar would be for detecting surface ships ... on the surface, aren't there waves and other ships that distort the motor sounds? -Han Kim
