US and Canadian warplanes “detected, tracked, and intercepted” two Russian TU-95 and two PRC H-6 military aircraft within Alaska’s Air Defense Identification Zone (ADIZ) on Wednesday, NORAD said.
The aircraft did not enter US or Canadian sovereign airspace and were not considered a threat, NORAD said.
“NORAD will continue to monitor competitor activity near North America and meet presence with presence,” the binational command said in a statement, Al Jazeera reported.
Intercepting an aircraft is military speak for contacting a foreign aircraft by electronic or visual means.
Countries including the US, China, India and Japan have unilaterally declared ADIZs that require foreign military aircraft to identify themselves upon entering a specific zone of airspace.
Unlike sovereign airspace, ADIZs are not recognized in international law or overseen by any international body.
Russian military activity is not uncommon off Alaska’s coast.
In February, NORAD said it had detected four Russian warplanes operating in the Alaska ADIZ.
On Sunday, Moscow said it had scrambled fighters to intercept two US bombers that approached the Russian border over the Barents Sea in the Arctic.
