The US Navy no longer has nuclear powered cruisers or destroyers. The only nuclear powered surface ships are aircraft carriers.

Aircraft carriers must be able to achieve the same speed in order for them to be able to launch and recover aircraft. The US Navy no longer has nuclear powered cruisers or destroyers.
Best Answer: Military submarine speeds are generally unpublished. The Alfa class Russian attack submarine is generally held to be the fastest with a speed of 43-45 knots. To convert knots to MPH multiply by 1.15 which guves a speed of 49-52 MPH. Source(s):
