New Generation of Akash Surface-to-Air missile
The DRDO successfully flight-tested a new generation of Akash surface-to-air missiles from an integrated test range off the coast of Odisha, enhancing air defence capabilities. Compared with the original version, the new variant of Akash-NG has a slightly better range and can strike targets at a distance of about 25 kilometers. During testing, the missile demonstrated the high manoeuvrability required to eliminate rapid and agile aerial threats.
Akash is India’s first indigenously manufactured medium-range Surface-to-Air missile capable of engaging multiple targets from multiple directions.
It is capable of being launched from mobile platforms such as battle tanks or wheeled trucks. It has a kill probability of nearly 90%.
The missile is aided by an indigenously developed radar known as ‘Rajendra,’ which is capable of handling multiple targets from multiple directions in group or autonomous mode.
Indigenously Developed MPATGM for Minimum Range
In a major push for AatmaNirbhar Bharat and the strengthening of the Indian army, DRDO successfully conducted flight tests on the indigenously developed low-weight, firepower and forget Man Portable Anti-Tank Guided Missile (MPATGM).
The test successfully validated the minimum range.
The maximum range of the missile has already been successfully flight tested.
The missile is equipped with the most advanced miniature infrared imaging seeker and advanced avionics.
The test made the development of an indigenous third-generation MPATGM nearly completed.
Sero Survey – Population Affected by Covid
Antibodies against the coronavirus are present in two-thirds of India’s population. 67.6 percent of adults were seropositive, and more than 62 percent were unvaccinated. Around 400 million of India’s 1.4 billion people do not have antibodies
