US Navy hopes super-stealth ship answers a rising China

A super-stealthy warship that could underpin the US 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 $US3 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.

With the first of the new ships set to be delivered in 2014, the stealth 
destroyer is being heavily promoted by the Pentagon as the most advanced 
destroyer in history - a silver bullet of stealth. It has been called a perfect 
fit for what Washington now considers the most strategically important region 
in the world - Asia and the Pacific.

Though it could come in handy elsewhere, like in the Gulf region, its ability 
to carry out missions both on the high seas and in shallows closer to shore is 
especially important in Asia because of the region's many island nations and 
China's long Pacific coast.

"With its stealth, incredibly capable sonar system, strike capability and lower 
manning requirements - this is our future," Admiral Jonathan Greenert, chief of 
naval operations, said in April after visiting the shipyard in Maine where they 
are being built.

On a visit to a major regional security conference in Singapore that ended on 
Sunday, US Defence Secretary Leon Panetta said the Navy will be deploying 60 
per cent of its fleet worldwide to the Pacific by 2020, and though he didn't 
cite the stealth destroyers he said new high-tech ships will be a big part of 
its shift.

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.

Down the road, the ship is to be equipped with an electromagnetic railgun, 
which uses a magnetic field and electric current to fire a projectile at 
several times the speed of sound.

But cost overruns and technical delays have left many defence experts wondering 
if the whole endeavour was too focused on futuristic technologies for its own 
good.

They point to the problem-ridden F-22 stealth jet fighter, which was hailed as 
the most advanced fighter ever built but was cut short because of prohibitive 
costs. Its successor, the F-35 Joint Strike Fighter, has swelled up into the 
most expensive procurement program in US Defence Department history.

"Whether the Navy can afford to buy many DDG-1000s must be balanced against the 
need for over 300 surface ships to fulfill the various missions that confront 
it," said Dean Cheng, a China expert with the Heritage Foundation, a 
conservative research institute in Washington. "Buying hyperexpensive ships 
hurts that ability, but buying ships that can't do the job, or worse can't 
survive in the face of the enemy, is even more irresponsible."

The Navy says it's money well spent. The rise of China has been cited as the 
best reason for keeping the revolutionary ship afloat, although the specifics 
of where it will be deployed have yet to be announced. Navy officials also say 
the technologies developed for the ship will inevitably be used in other 
vessels in the decades ahead.

But the destroyers' $US3.1 billion price tag, which is about twice the cost of 
the current destroyers and balloons to $US7 billion each when research and 
development is added in, nearly sank it in Congress. Though the Navy originally 
wanted 32 of them, that was cut to 24, then seven.

Now, just three are in the works.

"Costs spiraled - surprise, surprise - and the program basically fell in on 
itself," said Richard Bitzinger, a security expert at Singapore's Nanyang 
Technological University. "The DDG-1000 was a nice idea for a new modernistic 
surface combatant, but it contained too many unproven, disruptive technologies."

The US Defence Department is concerned that China is modernising its navy with 
a near-term goal of stopping or delaying US intervention in conflicts over 
disputed territory in the South China Sea or involving Taiwan, which China 
considers a renegade province.

China is now working on building up a credible aircraft carrier capability and 
developing missiles and submarines that could deny American ships access to 
crucial sea lanes.

The US has a big advantage on the high seas, but improvements in China's navy 
could make it harder for US ships to fight in shallower waters, called 
littorals. The stealth destroyers are designed to do both. In the meantime, the 
Navy will begin deploying smaller Littoral Combat Ships to Singapore later this 
year.

Officially, China has been quiet on the possible addition of the destroyers to 
Asian waters.

But Rear Admiral Zhang Zhaozhong, an outspoken commentator affiliated with 
China's National Defence University, scoffed at the hype surrounding the ship, 
saying that despite its high-tech design it could be overwhelmed by a swarm of 
fishing boats laden with explosives. If enough boats were mobilised some could 
get through to blow a hole in its hull, he said.

"It would be a goner," he said recently on state broadcaster CCTV's military 
channel.
