March 23 (Bloomberg) -- The U.S. Navy, after nearly six years of warnings from Pentagon testers, still lacks a plan for defending aircraft carriers against a supersonic Russian-built missile, according to current and former officials and Defense Department documents.

The missile, known in the West as the ``Sizzler,'' has been deployed by China and may be purchased by Iran. Deputy Secretary of Defense Gordon England has given the Navy until April 29 to explain how it will counter the missile, according to a Pentagon budget document.

The Defense Department's weapons-testing office judges the threat so serious that its director, Charles McQueary, warned the Pentagon's chief weapons-buyer in a memo that he would move to stall production of multibillion-dollar ship and missile programs until the issue was addressed.

Well, the sinodefence-site mentions the missile:

The Sizzler is smaller in size and lighter. I think the main difference is that the sunburn travels at supersonic speeds all the time, therefore requiering a big load of fuel, wich in turn makes the missile big and heavy. The Sizzler cruises at subsonic speeds and goes supersonic in terminal phase. But there are different versions of the "Club" some are "conventional" subsonic CMs over the entire flight.
The range is rather bigger than the sunburn's.

And I think the Sizzlers also have the capability of interoperability. Meaning they can exchange info. One "lead" missiles flies at high altitude searching for targets with it's radar, while the other missiles of a barrage stay low and recieve info from the lead-missile.
