Secret Code to Crack NDA

National Defence Academy (NDA)

The National Defence Academy (NDA) is India’s premier joint training institution for young aspirants who want to become officers in the Indian Army, Indian Navy, or Indian Air Force. Located in Khadakwasla, Pune, it’s the world’s first tri-service academy, where cadets from all three services train together before going on to their respective service academies for advanced training.

The NDA was established in 1954 and has produced some of India’s most decorated military leaders. The academy is known for its rigorous physical, academic, and leadership training that shapes cadets into disciplined and capable officers.

Trailblazing Women Cadets

“The National Defence Academy (NDA) is set to make history on May 30, 2025, as it graduates its first-ever batch of 17 women cadets alongside approximately 300 male cadets. This landmark event follows the Supreme Court’s 2021 directive that opened NDA admissions to women, leading to the induction of the first female cadets in 2022”

Future Assignments

Post-graduation, these pioneering women cadets will proceed to their respective service academies for further training:

9 cadets will join the Indian Army
5 cadets will join the Indian Air Force
3 cadets will join the Indian Navy

This historic graduation not only marks a significant step toward gender inclusivity in the Indian Armed Forces but also sets a precedent for future generations of women aspiring to serve the nation in uniform.

Joining the National Defence Academy (NDA) is not just about wearing a uniform — it is about carrying the pride and honor of the nation on one’s shoulders, embracing a life of discipline, courage, and selfless service. At NDA, a cadet learns to rise before dawn, push past personal limits, lead with integrity, and forge lifelong bonds, all while preparing to serve something greater than oneself. The academy does not merely select the strongest or the smartest; it selects those who refuse to give up, those whose love for the country outweighs their fear of failure, and those ready to live by the motto “Service Before Self.” Choosing NDA means stepping onto a path of purpose, sacrifice, and national pride — a journey that transforms ordinary individuals into extraordinary defenders of the motherland.
