K-4 Missile

India on Friday successfully test-fired the K-4 submarine-launched ballistic missile off the coast of Visakhapatnam for the second time this week, seen as a major milestone to augment India's naval prowess.

India on Sunday successfully test-fired the 3,500 km strike range nuclear-capable K-4 submarine-launched ballistic missile off the coast of Andhra Pradesh, further strengthening capabilities to hit enemy targets from submarines.

Nuclear capable ballistic missile K-4 was test-fired from nuclear submarine Arihant, both of which have been indigenously developed, officials said on Wednesday.

Expressing concern over India's recent ballistic missile launch, the US has said such actions could potentially "increase" the risk to nuclear security and have an impact on regional security.
