India joined the exclusive group of submarine constructing nations on February 7, 1992, with the commissioning of INS Shalki. The MDL built this submarine and went on to commission INS Shankul on May 28, 1994. They are still in service.
Khanderi is named after the Island fort of Maratha forces, which played a vital role in ensuring their supremacy at sea in the late 17th century. Khanderi is also the name of Tiger Shark, an MDL official said.
The submarine is built according to the principle of modular construction, which involves dividing the submarine into a number of sections and outfitting them concurrently.
The equipment is mounted in a special manner and then embarked into the sections. The complexity of the task increases exponentially as it involves laying kilometres of cabling and piping in extremely congested compartments.
