The INAS 315 was an Indian naval air squadron based at INS Hansa, Goa.
With the induction of the Il-38s, the Navy acquired modern maritime reconnaissance and fixed-wing Anti Submarine Warfare (ASW) capability.
In January 1978, the squadron aircraft using the on board Magnetic Anomaly Detector (MAD) equipment successfully located the wreckage of the ill-fated Air India Jumbo which had crashed soon after take-off of the Mumbai coast.
[5] On 1 October 2002, two Il-38s of INAS 315 collided in mid-air during a flypast near Dabolim, Goa, to celebrate the 25th anniversary of the squadron.
The collision and subsequent crashes killed all six crew members in each aircraft and three bystanders on the ground.
