The Andaman and Nicobar administration set a Guinness World Record by unfurling the world’s largest underwater Indian national flag at Radhanagar beach [1].

The event aims to highlight India's commitment to marine tourism and adventure activities while fostering national pride through a high-profile maritime achievement [1].

Located on Swaraj Dweep, also known as Havelock Island, the operation involved a coordinated effort between the local administration and various agencies [1]. The tricolour measured 60 meters by 40 meters [2].

Approximately 200 divers participated in the record-breaking attempt [3]. The group included three teenagers who joined the professional divers to deploy the massive fabric beneath the surface [3].

The achievement was officially recognized as the world’s largest underwater national flag [4]. This effort was designed to draw international attention to the natural beauty and diving potential of the Andaman and Nicobar Islands [1].

Organizers coordinated the logistics to ensure the flag remained visible and intact during the unfurling process. The event serves as a promotional tool for the region's tourism sector, focusing on the intersection of sport and patriotism [1].

The tricolour measured 60 meters by 40 meters.

By securing a Guinness World Record, the Andaman and Nicobar administration is leveraging 'stunt tourism' to reposition the islands as a premier destination for adventure and scuba diving. This move aligns with broader national goals to diversify tourism revenue beyond traditional sightseeing by highlighting the region's unique marine biodiversity and geography.
