The Naval Science and Technological Laboratory (NSTL) is one of the premier laboratories under the Defence Research and Development Organisation (DRDO), located in Visakhapatnam. NSTL plays a crucial role in strengthening India’s underwater defence capabilities by developing advanced naval weapon systems and cutting-edge marine technologies.
Established with a mission to empower the Indian Navy, NSTL focuses on research and development of torpedoes, underwater sensors, control systems, and high-end naval engineering solutions. The lab brings together some of India’s brightest scientists and engineers to work on mission-critical defence technologies that safeguard the nation’s maritime borders.
For students and researchers, NSTL is not just a laboratory, it is a centre of excellence where innovation meets national service. An internship here offers exposure to real-time defence projects, hands-on technical learning, and mentorship from experts working at the forefront of naval research.
DRDO NSTL Internships are among the most prestigious defence research internships available to engineering and science students in India. The Naval Science and Technological Laboratory offers both short-term internships (8 weeks) and long-term internships (6 months), providing students with an opportunity to gain hands-on experience in cutting-edge defence R&D. Interns get exposure to real projects related to underwater naval warfare systems and marine defence technologies developed for the Indian Navy. Selected students may contribute to research in advanced torpedo systems, working on areas such as propulsion systems, guidance and control algorithms, acoustic homing technology, warhead integration, and hydrodynamic optimization. The internship also provides expert mentorship, valuable practical exposure, and a completion certificate from one of India’s most prestigious DRDO laboratories.
Six Months Internship For B.Tech, M.Tech & M.Sc. students.
Every year DRDO-NSTL announces internships for students who want to do 6-month long internships at their facility in Visakhapatnam. Students from Electronics, Mechanical, Computer Science, Chemical, Electrical, Instrumentation, Naval Architecture, Physics & Chemistry can apply for the internship. The DRDO NSTL internship will be announced in April-May. The basic requirement is 75% in B.Tech, MSc or M.Tech.
DRDO labs typically require:
Without this, applications are often rejected.
You also need to send the following once you are selected, so keep them ready.
How to Apply: Candidates must send a scanned copy of the application form duly filled in all respects, along with the reference/request letter from their college for the paid internship (as per the attached format), to the Director, NSTL via email only; no hard copy of the application will be accepted. Applications should be forwarded to intern-hrd@gov.in, and the email subject must be written as “Application for Paid Internship with Branch Code for which the Candidate is Applying.” The last date to submit the application is 23 March 2026 at 17:00 hrs, and emails received after the specified date and time will not be considered.
Two Months Internship For B.Tech, M.Tech & MSc. students.
DRDO NSTL announces an internship every year in the month of June for 6 months internship for final year B.Tech students. A student who has completed third year can attend the internship. It is advised to apply for the DRDO-NSTL internships in the month of march if you are planning to do the internships in the month of May-June. The basic requirement is 75% in B.Tech, MSc or M.Tech.

Underwater Weapon Systems (Torpedoes): NSTL plays a pivotal role in the development and advancement of India’s underwater weapon systems, particularly torpedoes designed for the Indian Navy. The laboratory has been instrumental in systems such as Varunastra, India’s indigenous heavyweight torpedo, and TAL Shyena, a lightweight torpedo system. Research in this domain exposes students to the complete lifecycle of underwater weapon development — from conceptual design and simulation to testing and operational deployment in marine environments.
Internship Research Areas
Underwater Sensors & Sonar Technologies: A core strength of NSTL lies in underwater sensing and sonar technologies. The lab develops advanced systems for submarine detection, underwater surveillance, and acoustic countermeasures. Research combines hardware innovation with sophisticated signal processing techniques to enhance maritime situational awareness and defence readiness.
Internship Research Areas
Hydrodynamics & Marine Engineering: Hydrodynamics and marine engineering form the scientific foundation of underwater system design at NSTL. The lab focuses on improving underwater vehicle performance through experimental validation and advanced simulations. Students gain exposure to both theoretical modelling and practical testing environments.
Internship Research Areas
Control Systems & Embedded Systems: NSTL develops sophisticated real-time control systems and onboard electronics for underwater platforms. This area integrates electronics, embedded systems, and software engineering to create reliable and autonomous defence technologies.
Internship Research Areas
Materials & Chemical-Based Research: NSTL also undertakes advanced materials and chemical research to ensure reliability and performance in harsh underwater environments. This research supports propulsion systems, durability, and long-term operational efficiency.
