On the quiet coast of Kerala, a young girl would often watch rockets soar into the sky. The roar of each launch stirred her mind with curiosity and wonder. She stood still for long moments, gazing at the trails of smoke above the sea, unaware that those fleeting sights were planting seeds of ambition. Years later, that same girl would emerge as a leading scientist in India’s defence programme. The world would come to know her as the “Missile Woman of India,” but it all began with simple curiosity.

Tessy Thomas was born in April 1963 in Alappuzha, a coastal town in Kerala. Her father ran a small business, and education was very important in their home. The family lived not far from the Thumba Equatorial Rocket Launching Station (TERLS) in Thiruvananthapuram. Watching rockets launch from the nearby facility fascinated her deeply. She often wondered how machines could travel so far into the sky. Those early sights quietly shaped her interest in science and technology.

Life brought difficulties when Tessy Thomas was still a child. Her father suffered a stroke that left him partly paralysed. Her mother worked hard to support the family and manage the household. Watching this struggle taught Tessy the value of strength and responsibility. Despite these challenges, she stayed focused on her education. She showed a strong interest in mathematics and physics during her school years.

At a time when few women studied engineering, Tessy Thomas chose that path with confidence. She enrolled at Government Engineering College, Thrissur, to study electrical engineering. Her interest in missile systems slowly grew during her college years. She became curious about how defence technology worked. Her dedication to science kept getting stronger with every step. These years helped build the foundation for her future work.

After engineering, Tessy Thomas continued her studies in missile technology. She joined the Defence Institute of Armament Technology, now called Defence Institute of Advanced Technology. There she studied guidance and control systems used in missiles. Her training gave her a deeper knowledge of defence technology. In 1988, she joined the Defence Research and Development Organisation, known as DRDO. This step marked the beginning of her long career in India’s missile programme.

At DRDO, Tessy Thomas worked under scientist APJ Abdul Kalam. At that time, Abdul Kalam was leading India’s missile development projects. His guidance helped young scientists grow in confidence and skill. Tessy learned from his leadership and vision. The experience shaped her career in many ways. It also strengthened her role in India’s growing missile programme.

Over the years, Tessy Thomas became closely involved with the Agni missile programme. She worked on guidance systems, navigation technology, and flight control methods. These systems help missiles travel long distances with accuracy. Her knowledge and dedication made her an important member of the team. Slowly, she gained greater responsibility within the programme. Her work contributed to major progress in India’s defence technology.

Tessy Thomas later became the project director for the Agni-IV missile. This long-range missile can travel more than 4,000 kilometres. Under her leadership, the missile was successfully tested in 2011. The test was an important moment for India’s strategic defence programme. It showed the strength of years of research and teamwork. After this success, her reputation as a leading scientist grew widely.

Along with her demanding career, Tessy Thomas also managed family life. She is married to naval officer Saroj Kumar. The couple has a son and a supportive family environment. Long hours of research and testing often brought great pressure. Missile launches represent years of work by many scientists and engineers. For Tessy Thomas, each successful test carried great pride and responsibility.

Tessy Thomas later became Director General of Aeronautical Systems at DRDO. Her achievements helped break barriers for women in science and defence research. She also received honours like the Lal Bahadur Shastri National Award. From a curious child watching rockets to a leading scientist, her journey is remarkable. Her story shows how determination and education can shape a life. Today, Tessy Thomas inspires many young students, especially girls, to pursue science and dream bigger.
