Experts question NSB’s missile scoop

MYSTERY:Roger Cliff, an independent military expert, said it was unlikely US analysts would be unaware of the deployment of a new type of missile by China

By J. Michael Cole  /  Staff Reporter

The lack of US intelligence on a new type of short-range ballistic missile allegedly deployed by China has led some defense specialists to conclude that the projectile could be a medium-range missile already known to US authorities.

Debate over the existence of the Dong Feng-16 (DF-16) emerged soon after National Security Bureau (NSB) Director Tsai Der-sheng (蔡得勝) informed the legislature on March 16 that his agency had intelligence proving that the People’s Liberation Army (PLA) had finished testing and had deployed a new type of missile. In his testimony, Tsai said that some of the missiles, with a range of between 800km and 1,000km, were targeting Taiwan.

The faster re-entry of a longer-range ballistic missile, experts said, would make it more difficult for interceptors, such as Taiwan’s PAC-3, to defend against them.

With scant specific references in the literature and no confirmation from other intelligence agencies, some experts have wondered whether Tsai’s DF-16 might not be a variant of an existing short-range ballistic missile (SRBM), such as the DF-11 or DF-15, of which more than 1,000 are targeted at Taiwan.

However, some defense specialists approached by the Taipei Times said that as older SRBMs had been developed in the 1980s and fielded in the 1990s, it would not be surprising, as per industrial cycles, for an altogether new type of missile to be developed.

While variants of a missile are indicative of minor design improvements — for example, the DF-15C, which some reports say could serve as a longer-range upgrade at the Second Artillery’s Leping SRBM Brigade in Jiangxi Province — new designations, such as the DF-16, imply fundamental design changes, such as advances in solid rocket fuel, guidance systems and warhead design.

However, the lack of specifics provided by Tsai, who claimed Taiwan had sources unavailable to its allies, has led some analysts to conclude that rather than a brand new type of SRBM, the DF-16 could in fact be a medium-range ballistic missile (MRBM) already known to US intelligence, the CSS-X-11.

A spokesperson for the NSB would not comment on the matter when contacted by the Taipei Times yesterday.

That view was reinforced by comments by an unnamed military intelligence official, also on March 16, to the effect that the new missile could have a range of between 1,000km and 1,500km, making it, according to the US definition, a MRBM rather than a SRBM.

A week prior to Tsai’s announcement, an article in the Washington Times said the US intelligence community had assessed that on Jan. 11 last year, the PLA had successfully intercepted a CSS-X-11 MRBM launched from the Shuangchengzi Space and Missile Center in Gansu Province using a SC-19 anti-satellite missile. The story, based on a US Department of State cable made public by WikiLeaks, said that while little was known about the CSS-X-11, it could be an extended-range variant of the CSS-7 (DF-11) short-range missile.

US missile warning satellites had detected the launches and the intercept at an altitude of about 250km, the report said.

An intercept at an altitude of 250km would confirm that the ballistic missile had a range of at least 1,000km.

The “X” in CSS-X-11 means the missile was still in development at the time of the report, meaning that if the MRBM has since been deployed, it would be known as the CSS-11.
