Detailed Insights
The expedition, launched on 11 September 2025 and escorted home on 22 July 2026, was the maiden tri‑service circumnavigation involving women officers from the Army, Navy and Air Force. The nine‑person crew navigated the 50‑foot, self‑made IASV Triveni across four oceans, with the Defence Minister’s virtual inauguration in Mumbai marking a historic moment.
Covering 25,500 nautical miles in 314 days, the voyage crossed every meridian of longitude, crossed the equator twice, intersected the International Date Line, and rounded the three most formidable capes: Cape Leeuwin (Australia), Cape Horn (South America) and the Cape of Good Hope (South Africa). Crossing the Drake Passage—the world’s deadliest maritime channel—enabled the crew to become members of the exclusive Cape Horners Society, a tradition reserved for sailors who have successfully rounded Cape Horn.
Beyond navigation, the journey showcased Aatmanirbhar Bharat through the vessel’s indigenous engineering, self‑sufficient defence capability, and technological innovation. The expedition also underscored the rising phenomenon of Nari Shakti within the armed forces, illustrating gender inclusivity, resilience, and leadership in high‑stakes military operations.
