And don’t you like the “ballistic” pun in the following quote from the article:

“Russian built submarines armed with the potent Klubs are expected to play a critical role in any conflict in the South China Sea. According to one analyst, the land-attack cruise missiles mark a “massive shift” advancing Vietnam’s naval capabilities. “They’ve given themselves a much more powerful deterrent that complicates China’s strategic calculations.”

It is believed Chinese warships have no effective defense against missile like Klub, which why they have gone ballistic about Russia selling them to Vietnam.

While the Kilos are being built, Russia and India are currently in charge of training Vietnamese officers who will work in the submarines.”
