India's government-run Defence Research and Development Organisation (DRDO) successfully test-fired on 19 January its locally developed, nuclear-capable K-4 intermediate-range submarine-launched ballistic missile (SLBM) off the country's east coast to its longest range so far, military sources revealed on 20 January.
Although no official confirmation has yet been provided by the DRDO of the 19 January day-time firing of the SLBM, the sources told Jane's on condition of anonymity that the 12 m-long K-4 was launched from an underwater pontoon near Visakhapatnam out to a distance of about 2,200 km.
This was 1,300 km short of the maximum 3,500 km range claimed by the DRDO, but reportedly "far in excess" of the range the missile had achieved in its previous test-firing from a similarly submerged platform in March 2016, the sources stated.
