A report claims that a Russian-built submarine operated by the Indian Navy was able to defeat a Los Angeles-class US Navy sub. The INS Sindhudhvaj engaged the USS City of Corpus Christi in the Bay of Bengal. The two submarines worked to track each other down in the open water, and the INS Sindhudhvaj allegedly prevailed.

The incident took place during an annual training exercise between the Indian, Japanese, and American forces in October 2015.

India’s Kilo-class diesel-electric attack sub, the INS Sindhudhvaj, according to the Indian Navy, “killed” the USS City of Corpus Christi during the exercise.

“The way it happens is that the Sindhudhvaj recorded the Hydrophonic Effect (HE) – simply put, underwater noise – of the nuclear powered submarine and managed to positively identify it before locking on to it. Being an exercise what did not happen was the firing,” said an Indian naval officer, according to a report by Yahoo.

The INS Sindhudhvaj allegedly used simulated 533mm torpedo fire to “sink” the US vessel during the scheduled training event.

India’s claims of success are not confirmed by other participants in the training exercise. Additionally, the rules of engagement and similar details were not provided in the original report, so the conditions under which the US craft was defeated are not clear.

However, a Kilo-class sub could defeat a Los Angeles-class vessel, as the design is considered dated by today’s standards.

Additionally, the diesel-electric design of the Kilo-class make these submarines especially quiet, and they have often been described as a “black hole” or “a hole in the water” by those who face them.

The US has been working to replace many Los Angeles-class submarines with the quieter and more technologically advanced Virginia-class.
