Indian Navy Scorpene-class Submarines in Sea Trials & SUT Torpedo Firing Test
 
The Indian Navy announced that Khanderi, the second of the six Scorpene-class submarines being built in India at MDL, sailed out on 01 June 2017 from Mumbai harbour for her maiden sea sortie. Meanwhile, Kalvari, the first ship of the class, conducted its first torpedo firing.

Khanderi's initial sea trial was also the first major trial for her propulsion plant and a very important milestone in the construction programme. The successful trial moved the submarine a significant step closer to her induction into the Indian Navy later this year. She will now be put through her paces via a rigorous set of trials, which are designed to test her operating envelop to the maximum.

As part of the ongoing sea trials, the first indigenously built, Scorpene-class submarine Kalvari undertook it's first torpedo firing on 26 May 2017. A German SUT heavyweight torpedo was used for the test.

SUT Torpedo
The SUT heavyweight wire-guided torpedo is a dual-purpose weapon that can be launched off surface ships and submarines, and from shore positions. Its successor is the DM2A3/4 (Seehecht) by Atlas Elektronik. The SUT torpedo is designed to operate effectively in both deep and shallow water and against surface and underwater targets. The Mod 1 variant is a developed version of the SUT Mod 0 with modifications to meet specific user requirements. It was delivered to India and Chile. The SUT is reported to have a range of 15.1 nautical miles at 18 knots or 8 nautical miles at 35 knots. The SUT is already fitted aboard the Type 209 SSK (Shishumar-class submarine) of the Indian Navy. Kalvari class Submarines were originally planned to be fitted with the Black shark heavyweight torpedo by Italian company WASS / Leonardo but this plan was stopped follwoing a bribery scandal. Down the road, the Kalvari class may receive the Varunastra, a new heavyweight torpedo currently being developped in India by the DRDO.

In March this year, Kalvari conducted its first SM39 Exocet anti-ship missile launch.

P75 Scorpene
Six submarines of the P75 project are being built by MDL through technology transfers from DCNS for the Indian Navy. "Kalvari", the first Scorpene class diesel-electric submarine (SSK) was launched in the water on 28th October 2015 in Mumbai. It started sea trials in May last year. The sea trials campaign went well and left Indian submariners with a very good impression. "Khanderi", the second submarine in the series, was launched in January 2017 and started sea trials in June. Four other submarines will follow in the wake of Khanderi, at intervals of nine months.
