According to WorldTribune, Vietnam will receive the BrahMos which is considered one of the most effective and lethal anti-ship missiles in the world, with speeds reaching Mach 2.8 to 3.0. The BrahMos can be launched from submarines, ships, aircraft or land. It was developed jointly by India’s Defense Research and Development Organization (DRDO) and Russia’s NPO Mashinostroeyenia. The missile is heavily based on the Russian P-800 Oniks cruise missile and other similar sea-skimming Russian cruise missile technology.

On September, 2016 Indian PM Narendra Modi visited Vietnam and had bilateral talks with his Vietnamese counterpart Nguyen Xuan Phuc, as well as President Tran Dai Quang. Vietnam is India’s important strategic partner and the visit is aimed at further strengthening bilateral ties, including defense, security and trade. During the trip, Modi announced a $500 million credit line to Vietnam to buy defence equipment, on top of a $100 million given previously to help it buy patrol boats. The two sides have also agreed for training of Vietnamese air force pilots to operate Su-30 Russian fighter planes.
It was published by Reuters  in Feb 2017 that: “India is in talks to sell short range surface-to-air missiles to Vietnam, the head of India's defense research agency said on Wednesday, in what would be its first transfer of such weapons to the Southeast Asian country.”
