India says it has successfully test-fired a submarine-launched ballistic missile, or SLBM, in the Indian Ocean.

The Indian government announced on Friday the missile had been launched from the INS Arihant in the Bay of Bengal.

The INS Arihant is India's first domestically built nuclear-powered submarine and went into full operation in 2018.

Government officials did not provide details about the launch, such as exact location, type of missile and number of test-firings.

Multiple Indian media outlets report this is the first time the government has officially announced an SLBM test by the submarine.

India is ramping up efforts to strengthen its navy. The country commissioned its first locally made aircraft carrier in September.

Some observers say the Indian government made the announcement as part of an effort to keep China in check, as Beijing is stepping up maritime activities around the Indian Ocean under its Belt and Road initiative.
