No US defense vs supersonic cruise missiles The US and UK aircraft carrier battle groups do not have any known defense against the new supersonic missiles of their adversaries.
The Phalanx and Aegis ship defense systems may be effective against subsonic cruise missiles like the Exocets or Tomahawks, or exo-atmospheric ballistic missiles, but they are inadequate against the sea-skimming and supersonic Granits, Moskits and Yakhonts or similar types (Shipwreck, Sunburn and Onyx - North Atlantic Treaty Organization codenames) of modern anti-ship missiles in China's inventory.
Not only China and Russia have these modern cruise missiles, so do Iran, India and North Korea. These missiles can be delivered by SU-27 variants, SU-30s, Tu22M Blackjacks, Bears, J6s, JH-7/As, H-6Hs, J-10s, surface ships, diesel submarines or common trucks. Adding to the problems facing aircraft carriers are the SHKVAL or "squall" rocket torpedoes installed in some Chinese and Russian submarines and surface ships.
At 6,000 lbs apiece, these torpedoes travel at 200 knots (or 230 miles per hour) with a range of 7,500 yards guided by autopilot.
They are designed to sink aircraft carriers and nuclear submarines. Again, it is unfortunate for the US and UK to have no known or existing defenses against this new generation of rocket torpedoes.
