The system, known as JLENS, is designed to detect incoming cruise missiles. The North American Aerospace Command (Norad) did not specify the nature of the threat, but the deployment comes nine months after the Norad commander, General Charles Jacoby, admitted the Pentagon faced “some significant challenges” in countering cruise missiles, referring in particular to the threat of Russian attack submarines.
Those submarines, which have been making forays across the Atlantic, routinely carry nuclear-capable cruise missiles.
