India became an emerging nuclear power in 1998, the reason behind which was the nuclear test on 11 May 1998. After achieving this great success, the Prime Minister of India announced to celebrate 1999 as National Technology Day. Since India had conducted its most powerful nuclear test on May 11, that is why to remember this day, National Technology Day is celebrated every year on May 11.
Before demonstrating its nuclear power, India was considered a very weak country. Along with this, the countries which already had nuclear power, used to consider India below. After some time, the real turning point in this thinking of these countries came when India declared itself as the sixth country which has the power to make nuclear weapons.
In India, on 11 May 1998, when the Department of Atomic Research tested three nuclear bombs simultaneously in Pokhran, an earthquake up to 5.3 reactor scale was recorded in the surrounding areas. This test was named "Shakti" by the Research Department of India. Two days later i.e. on May 13, 1998 two more nuclear bombs were tested. On the same day, the Indian Security Department also tested Trishul missile and Hans-3 (training aircraft).
India's most powerful and successful nuclear test was done in 1998 and the great scientist Abdul Kalam was behind the execution of this entire test. The credit for handing over this work to Abdul Kalam goes to former Prime Minister Atal Vihari Vajpayee. All the nuclear tests were successfully tested only by the excellent guidance of Abdul Kalam ji. After this test, the central government had termed this achievement as India's biggest achievement.
