Chris Cavas of Defense News Offers Key Takeaways from CMSI’s Conference on “China’s Naval Shipbuilding: Progress and Challenges”
Christopher P. Cavas, “China’s Navy Makes Strides, Work Remains to Be Done,” Defense News, 24 May 2015.
NEWPORT, R.I. — It’s no secret that China has embarked on a major modernization and expansion plan for its Navy, and its aggressive building program, coupled with the placing in service of more modern submarines, an aircraft carrier, destroyers with ever-sophisticated sensors and a large number of long-range surface-to-surface missiles, is altering politics and strategies throughout the Asian theater.
What is not so clear is what sort of fleet the Chinese are building toward, and how far their industrial capability can take them.
That was the theme last week at a two-day conference here to discuss China’s naval shipbuilding progress and challenges. Presenters at the event, sponsored by the US Naval War College’s China Maritime Studies Institute, were in general agreement on several major themes — that China’s Navy will continue to grow and field ever-more capable systems, and that it remains a work in progress.
“That’s a good way to put it,” Andrew Erickson, a leading expert at the college on the People’s Liberation Army (Navy) — or PLAN — and one of the event’s organizers, said shortly after the conference ended.
“A lot of activity is occurring, there’s a lot of effort, they’re making achievements, but in this complex and difficult field it takes a lot of achievement to be accrued before that translates to a major increase in actual capability,” Erickson said.
“They are far from hopeless, they are moving ahead, but it is a long and rocky road.”
There was general agreement at the conference that the PLAN fleet now being created is heavily centered on anti-surface warfare, as evidenced by the construction of a growing number of destroyers, frigates and submarines armed with a wide variety of ship-killing missiles, many with ranges far in excess of similar missiles in service with the US Navy.
“Both surface vessels and subs seem to be largely focused on anti-surface warfare,” Erickson said. “That doesn’t mean they’re not working to progress in new directions, but it doesn’t seem to have borne as much fruit that we can easily see.” …
Many conferees took note of China’s development of an improved nuclear-powered ballistic missile submarine, the Type 094 Jin class, and predicted the first deterrent patrol could happen in 2016. But many speakers decried the overall performance of the new submarines as still a work in development, especially when it comes to propulsion engineering.
“Here’s where things become more demanding for them,” Erickson said. “They’re going to want to be able to build a significant number of [attack submarines] whose reactors are efficient, long-lasting, reliable and quiet enough. There’s no way to compensate for quietness if you don’t have it.”
Propulsion problems were cited by a number of presenters at the conference. China is lagging in engine development, many noted, and still produces a large number of power plants based on foreign designs. Chinese industry is able to produce diesel engines and gas turbines, but, Erickson said, “what still seems to be lacking is having the highest level of capability.”
Foreign-supplied engines remain a concern for China, some noted, and producing better engines will continue to be a focus.
With the Type 041 Yuan-class, China now is operating submarines equipped with Stirling air-independent propulsion (AIP) engines, a technology already in use in other navies.
“They want the ability to be quiet and not to have to surface to charge the batteries,” Erickson said. “They have achieved that with a Stirling capability in the Yuan class. But technology is always moving ahead. And in AIP, even if you’ve mastered it, is a highly complex system.”
And China, like Japan and Germany, is moving ahead with the development of improved lithium-ion (Li-Ion) batteries.
“Chinese researchers clearly see Li-Ion batteries as the wave of the future for conventional submarine propulsion,” Erickson said. “They’re not there yet, but they are determined to get there.”
“They are talking about putting them on a new generation of conventional subs sometime between now and 2020,” Erickson added, “but there is no indicator as yet of the type of submarine that might be.” …
