Is China's "Carrier-Killer" Really a Threat to the U.S. Navy?
It seems tomorrow will be a big day for China-military watchers around the world: the mighty DF-21D, or “carrier-killer” anti-ship ballistic missile (ASBM) will likely be one of the features of Beijing’s end of World War II celebrations. But how much should America or anyone else in Asia fear this supposed killer of carriers?
The “carrier-killer” has been a favorite topic of mine for some time now. The weapons are launched from a mobile truck-mounted launcher into the atmosphere, with most likely over-the-horizon radar, satellite tracking and possibly unmanned aerial vehicles each providing guidance to a target in the open oceans. It also incorporates a maneuverable warhead, or MaRV, to help find its target.
The DF-21D would be instrumental in striking a vessel in the open ocean or denying access to a potential opponent in transiting to a conflict zone, like in the East or South China Seas. An August 2011 report by Taiwan’s Ministry of National Defense warned that: “A small quantity of the missiles [was] produced and deployed in 2010.”
When looking at this weapon, there are really two basic questions I have been asking for years: How capable is it? And if capable, can U.S. Navy vessels defend against it?
First, to its capabilities. According to the most-recent and up-to-date open-source materials I can find, the weapon indeed has been tested, however, never against an ocean-going, noncooperative target. As frequent TNI contributor Andrew Erickson pointed out in his 2013 study of the DF-21D (the best open-source resource on the “carrier-killer” to date):
“Additional challenges and tests remain before the DF-21D reaches its full potential; however, senior U.S. and Taiwan officials in the last two years have confirmed separately that the ASBM is in the field. Additionally, the basic support infrastructure is already sufficient to provide basic targeting capabilities against U.S. aircraft carriers operating in the Western Pacific (if countermeasures are not considered).”
As Erickson also noted, from the same text:
“The ASBM’s physical threat to U.S. Navy ships will be determined by the development of associated information processing systems and capabilities. This is part of a larger analytical challenge in which Chinese “hardware” continues to improve dramatically, but the caliber of the “software” supporting and connecting it remains uncertain and untested in war. The missile components of the DF-21D already are proven through multiple tests, but China’s ability to use the missile against a moving target operating in the open ocean remains unproven. The supporting command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) technologies probably still lag behind the requirement to identify and track a U.S. aircraft carrier in real time under wartime conditions. Improving C4ISR capabilities, however, is a high priority in China’s military modernization program. U.S. countermeasures are another matter entirely: there is every reason to believe that they are already formidable.”
With the above analysis done in 2013, we have every reason to assume that China has worked hard to perfect this weapon. In multiple conversations I have had with U.S. defense officials over the last year, most are working under the assumption that the DF-21D would in wartime conditions be able to at least initially target an ocean-going vessel and track such a vessel through its course to the target. Keeping in mind that Beijing would not fire just one of these missiles in combat—and would likely attack its target with other types of missiles in a saturation-style strike—there is certainly reason for concern.
Can America Defend Against the DF-21D?
Assuming the DF-21D is ready for battle, can America defend against China’s mighty missile?
While opinions are clearly mixed—in speaking to many sources over the last several years on this topic—it seems clear there is great nervousness in U.S. defense circles. However, as time has passed, initial fears have turned towards a more optimistic assessment.
Back in 2012 when I spoke to noted defense expert Roger Cliff, he explained that:
“[O]ver-the-horizon radars used to detect ships can be jammed, spoofed, or destroyed; smoke and other obscurants can be deployed when an imagery satellite, which follows a predictable orbit, is passing over a formation of ships; the mid-course updates can be jammed; and when the missile locks on to the target its seeker can be jammed or spoofed.”
He continues, noting an actual kinetic strike on the missile in flight might be the hardest part:
