DRDO Develops Underwater Signaling Flares for Indian Navy Submarines

Imagine submarines need to talk to ships or planes above the water, but they can't use regular radios.

The DRDO has made special flares called Signal Star Naval Flares for this.

These flares are launched from the submarine and pop up to the surface.

Once up, they create bright lights, like red or green stars.

The red stars mean the submarine is in trouble, and the green ones are for safe signals.

These flares help the navy practice and communicate without giving away their location.

This is important for the navy, as it helps them communicate and be safe.
