It looks like Russia, China, and perhaps others can now easily sink our giant aircraft carriers, which are now sitting ducks! Also see:

Its 200 kiloton nuclear warhead has almost 20 times the explosive power of the atomic bombs dropped on Hiroshima. The U.S. Navy has no defence against this missile system

For decades, the USA owning the seas has been a myth, because of Russia, and now China too. China already has many state-of-the-art subs, and they’re estimated to surpass our above-water capability soon.

Those 345 MPH Supercavitating Torpedoes: Did You Know?
UPDATE: July-10-2008

The Peoples Republic of China reportedly bought 40 Shkval rocket torpedoes from Kazakhstan [71] in 1998. An improved version of the Shkval may be capable of a 300 knots speed (345 mph). France, the U.S., and Germany have also undertaken supercavitating torpedo development.

With a range of at least 3 to 4 miles, Shkval torpedoes reduce reaction times to travel that distance from 3 minutes to perhaps 40 seconds.

2.1    FOREIGN HELP FOR HI-TECH WEAPONS

Russian Assistance for Supercavitating Underwater Weapons

            Supercavitating underwater weapons move through water at very high velocities, at speeds up to greater than sound. They are able to do so because they form an air bubble, or cavitation, around the structure. Once launched, there is little defense against such high-speed underwater weapons.  They are envisioned for use as torpedoes, anti-torpedoes, anti-mine or as missiles that travel underwater and then air-launch near the shore to defeat anti-missile defenses.[69] Russia is a leader in supercavitation technology and in 1977 fielded the Shkval (Squal) rocket torpedo, which can achieve speeds up to 200kts, or 100 meters per second (230 mph) through water. An advanced version of the Shkval is reportedly capable of 300kts speed.[70] This version reportedly was being tested on the Russian Oscar-class SSGN Kusk that sank in August 2000.  The U.S., France and Germany also have supercavitating weapons research programs.

            In August 1998 the PRC was reported to have purchased 40 Shkval rocket torpedoes from Kazakhstan.[71] This could indicate that the PLA also has programs underway to develop supercavitating underwater weapons.  A Taiwanese source notes that the PLA has used these weapons to aid the development of its own supercavitating weapons, which may be in testing.[72] Developing such weapons would be consistent with the PLA’s efforts to adopt new technologies and to build weapons that exploit the weaknesses of the U.S.  U.S. sources reportedly have confirmed that a PLA Navy Officer perished on the Kurskwhen it sank.[73] There is speculation that he was there to observe the testing of a new version of the Shkval.
