For a future fracas . . .

HERE'S THE FIRST LOOK AT THE DDG-1000 ZUMWALT. It's a major part of the USN's answer to the Chinese navy's growth in Asian waters. It's a littoral vessel, designed for coastal patrols. Like everything these days, it's not cheap: according to the Washington Post/Associated Press, "Stealth destroyer, at over $3 billion apiece, is US Navy’s latest answer to rising China". 

A super-stealthy warship that could underpin the U.S. navy’s China strategy will be able to sneak up on coastlines virtually undetected and pound targets with electromagnetic “railguns” right out of a sci-fi movie.

But at more than $3 billion a pop, critics say the new DDG-1000 destroyer sucks away funds that could be better used to bolster a thinly stretched conventional fleet. One outspoken admiral in China has scoffed that all it would take to sink the high-tech American ship is an armada of explosive-laden fishing boats.

At 2.4 kilometres per second (5,400 mph), the air burns, no chemical propellant used.

Right now, it's could be, would be, should be, might be. And the Chinese say they are not impressed, but then again, what else are they going to say? HOWEVER, if this is NOT speculative, it may be an indication that the USN has made solid progress with the Polywell Fusion program, which is intended to power those rail-guns. The rail-guns, with a projected 200-mile/320km range, will be appearing later in the decade — if the USN solves the power-source problem.

The DDG-1000 and other stealth destroyers of the Zumwalt class feature a wave-piercing hull that leaves almost no wake, electric drive propulsion and advanced sonar and missiles. They are longer and heavier than existing destroyers — but will have half the crew because of automated systems and appear to be little more than a small fishing boat on enemy radar.
