The Defence Research and Development Organisation (DRDO) has developed light weight torpedo. The torpedo, developed under the project, Advanced Experimental Torpedo, is now named “Torpedo Advanced Light” (TAL). The torpedo
has undergone technical trials during 1994-1998 and user trials during
1998-2000.
User evaluation trials using designed and engineered models
of the Torpedo were conducted during 2003-2005. Navy
has termed these trials as successful and satisfactory. The expenditure
incurred on Research and development of the torpedo during 2003-04, 2004-05 and 2005-06 was Rs. 164.93 lakhs, Rs. 36.94 lakhs and Rs. 23.63 lakhs respectively.
Bharat Dynamics Limited, Hyderabad has submitted budgetary quotation for 25 numbers of torpedo
to Integrated Headquarters (Navy). Production will start immediately
after placement of order. This information was given by Defence Minister
Mr Pranab Mukherjee in a written reply to Mr Kuldeep Bishnoi on april
06.
Light Weight Torpedo (Advanced Experimental Torpedo)
is an anti-submarine weapon which can be fired from a flying/hovering
helicopter very close to the previously known location of enemy
submarine to have a definite kill probability. The torpedoes can also be
fired in a quick salvo from surface ships using torpedo Triple Tube Launchers (TTL).
Several front-end technologies are developed for the first time in
the country making it self reliant. Several other products using state
of art materials such as composites, titanium alloys are incorporated to
bring down the total weight of the torpedo without
sacrificing the strength requirements. High power sea water activated
batteries in compact size to fit into the 324 mm diameter shells, contra
rotating DC propulsion motors are the contribution of this project.
Sensor instrumentation packages, hybrid control and guidance motors are
fabricated within the country which were denied under the Technology
control regimes. Development of the light weight torpedo has resulted in several indigenous products which were hitherto imported. The fully integrated torpedo consists of 95% of indigenous components and sub-systems.
The torpedo
is capable of operating at depths of few hundred meters and homes on to
its prey by passive/active homing and explodes on impact to
destroy/damage the target submarine. Torpedo, on entry
into water, performs pre-programmed search patterns, detects the targets
and homes on to the target. Many user evaluations were conducted. The torpedo
met all of its required specifications and user acceptance criteria as
stipulated by the user and production orders are placed on M/s. BDL,
Hyderabad by the Indian Navy.
