The UPSC NDA 1 2026 application form has been officially released by the Union Public Service Commission (UPSC) for the National Defence Academy and Naval Academy Examination (I), 2026. Defence aspirants across India can now apply online for NDA 1 2026 through the official UPSC portal — upsconline.nic.in and upsc.gov.in — after the NDA 1 2026 notification was published on 10 December 2025.
The opening of the UPSC NDA 1 2026 online application form marks a pivotal opportunity for young aspirants to pursue a career in the Indian Army, Indian Navy, Indian Air Force, and Indian Naval Academy. According to the official UPSC notification, the NDA 1 2026 application window will remain active from 10 December 2025 to 30 December 2025, giving candidates a clear timeline to complete NDA 1 2026 registration online before the deadline.
The NDA 1 2026 exam date has also been officially announced as 12 April 2026, with the offline written test conducted across multiple exam centres in India. Aspirants preparing for the UPSC NDA 2026 exam should prioritise submitting their application forms early, ensuring all required details, documents, and fees are correctly completed well before the final submission date.
Under the NDA 1 2026 eligibility criteria, candidates must be unmarried males or females and born between 02 July 2007 and 01 July 2010 (approximately 16½ to 19½ years at the time of joining). This age eligibility ensures that the aspirants meet the UPSC’s requirements to join the prestigious defence academies.
For educational qualifications, applicants must have passed or be appearing in Class 12/10+2 from a recognised board. Specifically, for the Army wing, any stream is acceptable, while Air Force, Navy, and Naval Academy candidates must have studied Physics and Mathematics in their 10+2 education — a standard condition under the NDA selection rules.
A total of 394 vacancies have been announced for NDA & NA 1 2026, which include posts in the Army, Air Force, Navy, and Naval Academy. These positions offer a career path into the Indian Armed Forces as commissioned officers, making the UPSC NDA 2026 recruitment one of the most competitive and sought-after defence entrance examinations in the country.
To complete the NDA 1 2026 application form online, candidates must first finish the One Time Registration (OTR) on the UPSC portal. After OTR, aspirants can select “NDA & NA (I) Examination, 2026” in the application section, fill in personal and educational details, upload required documents such as photographs and signatures, and pay the application fee of ₹100 (with exemptions available for SC/ST, female candidates, and certain categories).
Once submitted, candidates should download the confirmation page and keep it safe for future reference, including admit card release and exam centre details. With the NDA 1 2026 registration officially underway, aspirants are encouraged to double-check all entries to avoid discrepancies that could affect their candidature.
The NDA 1 2026 written examination will consist of two papers — Mathematics and the General Ability Test (GAT) — as part of the first stage of the UPSC NDA selection process. Successful candidates will move forward to the SSB interview and subsequent medical examination phases, before final selection into the defence academies.
