The move is designed to counter China's build-up on its seven reclaimed islands in the Spratlys archipelago.
Carl Thayer, an expert on Vietnam's military at the Australian Defence Force Academy, said the deployment showed the seriousness of Vietnam's determination to militarily deter China as far as possible.
"China's runways and military installations in the Spratlys are a direct challenge to Vietnam, particularly in their southern waters and skies, and they are showing they are prepared to respond to that threat," he said. "China is unlikely to see this as purely defensive, and it could mark a new stage of militarization of the Spratlys."
