India on Saturday tested its indigenously produced torpedo in Vishakapatnam.
With this, it joined the elite club of eight countries to have such a capability.
Manufactured by the Hyderabad-based public sector undertaking, Bharat Dynamics, the torpedo would undergo further trials, a company spokesman said.
"The design of the torpedo involves state of the art technology areas including hydrodynamics, aerodynamics, structural design, electrical, electronics, electro-chemistry, and software," the spokesman said.
