Sagarika (pronounced: sɑːgərikɑː),[a] (Sanskrit - सागरिक 'Oceanic') also known by the code names K-15 or B-05 or PJ-08, is an Indian submarine-launched ballistic missile (SLBM) with a range of 750 kilometres (466 mi)[8][9][10] that was designed for retaliatory nuclear strikes.

It belongs to the K Missile family and forms a part of India's nuclear triad.

[11] The K-15 is a two-stage submarine-launched ballistic missile which uses a gas booster to eject out of its launch platform and rise up to the surface of water.

A solid rocket motor is fired after the missile reaches a fixed altitude.

[15] The development of the underwater missile launcher, known as Project 420, was completed in 2001 and handed over to the Indian Navy for trials.
