Why the name, why the mission

Tradition holds that Krishna's city, Dwaraka, was reclaimed by the sea after he departed the world. Submerged structures off the Gujarat coast, surveyed by India's National Institute of Oceanography since the 1980s, have long been associated by tradition with that lost city. KRSNA is named for him, and built toward that search.

Today, that means a small, portable, autonomous (optionally thin-tethered) underwater vehicle for heritage and subsea survey, harbour and hull-side inspection, hull sweeps, mine-like-object detection, and diver support — carried in one air-transportable case by a two-person team, launched from a jetty or a RHIB, and recovered on mission completion or on any abort. Positive buoyancy means loss of autonomy, power or link ends with the vehicle on the surface.
