Russia just tested this ultra-fast ship-killing missile

Russia carried out the latest test of a new high-speed cruise missile last week as part of a program that is raising concerns in the Pentagon about the threat the missile poses to American warships.

The test of the Zircon hypersonic missile was tracked by U.S. intelligence agencies, according to a senior defense official familiar with reports of the test. No other details of the test were available.

However, state-run Russian news reports say the Zircon can reach speeds of between Mach 6 and Mach 8, or between 4,600 and 6,100 miles per hour — enough to outpace any current missile defense interceptors.

Such high speeds pose dangers for Navy destroyers, cruisers, and aircraft carriers currently outfitted with anti-missile defenses but that are not capable of countering the missile.

Defense analysts said the test was probably carried out from a ground-based launcher near an area of the White Sea in northern Russia around May 30 — the date that Russian authorities issued an air closure notification for the region.

The Zircon has been billed by the Russians as an anti-ship cruise missile that media have said will be deployed on Moscow’s nuclear-powered missile cruisers. Production is expected to begin this year.

Vladimir Tuchkov, a military analyst, told the state-run Sputnik website that Zircon missiles will be deployed between 2018 and 2020.

“The Russian development of hypersonic weapons is clearly a very serious threat,” said Mark B. Schneider, a senior analyst at the National Institute for Public Policy and a former senior Pentagon official. The missile’s estimated range of up to 620 miles “would give it very great capability against defenses,” he added.

Mr. Schneider said the Pentagon is “clearly well behind” in the race for developing hypersonic weapons, and that the problem is not technology but a lack of funding. China also is developing a hypersonic missile called the DF-ZF.

The Pentagon is planning a test this year of a missile called the Advanced Hypersonic Weapon as part of its Conventional Prompt Strike program. That program until recently was dubbed the Conventional Prompt Global Strike and is seeking weapons capable of striking any location on Earth within minutes.
