| Source measurement | — | Shyena is electrically propelled, and can target submarines with a speed of 33 knots with endurance of six minutes in both shallow and deep waters. It can operate at depths of a few hundred metres and has self-homing, i.e. it can home in on targets by passive/active homing and explode on impact. Once launched, it can perform pre-programmed search patterns for available targets. The torpedo weighs around 220 kg.[source]Torpedo Advanced Light Shyena · Design and development; only the objects and conditions stated in this passage Advanced Light-Weight Torpedo (ALWT) is the 2nd generation of Shyena anti-submarine torpedo . The torpedo is developed by Naval Science and Technological Laboratory (NSTL). It can be launched from ship, helicopter or from a fixed wing aircraft. Based on inputs from the platform's sonar and Fire Control System inputs, certain preset parameters are given to the torpedo prior to launch in order to ensure the target is in a favourable position to acquire, home in and destroy the it. The torpedo boasts a dual-speed capability for which it has a range of 25 km (16 mi) at 25 kn (46 km/h) and a range of 12 km (7.5 mi) at 50 kn (93 km/h). It uses sea-water powered battery which eliminates the requirement of pre-launch charging. The ALWT will also form the warhead of the SMART anti-submarine missile along with a parachute-based release system. The torpedo is meant to replace Mark 46 torpedo in the Indian Navy's inventory. The torpedo will also be integrated on the Boeing P-8I Neptune fleet of the Indian Navy for anti-submarine warfare operations.[source]Torpedo Advanced Light Shyena · Advanced Light-Weight Torpedo (ALWT); only the objects and conditions stated in this passage BDL signed a third and fourth export contract for the Shyena torpedo in 2019 to an undisclosed friendly country. The value of the contract is ₹ 455.27 crore (equivalent to ₹ 566 crore or US$59 million in 2023) and ₹ 1.43 crore (equivalent to ₹ 1.6 crore or US$170,000 in 2023) respectively. The order is planned to be executed in 2020–21.[source]Torpedo Advanced Light Shyena · Exports; only the objects and conditions stated in this passage |
