In today’s world, no nation is a true friend of others. For self-defenses, you should make your own indigenous weapons so that in case of any knock with the enemy nation, they shouldn’t have any technological advantage.
The Advanced Air Defense System (AAD) is a single-stage solid fuel ABM missile designed to intercept ballistic missiles located in the atmosphere at an altitude of 30 km. Steering is similar to PAD steering with an inertial navigation system, mid-lane updates from ground radar and active radar in the final stage.
It is 7.5 meters high, weighs about 1.2 tons and has a diameter of less than 0.5 meters.
On December 6, 2007, AAD system was successful in intercepting a modified Prithvi-II missile as an incoming target as a ballistic missile. The inland atmosphere is intercepted at an altitude of 15 km. The interceptor and all the items that are made in the copybook method to validate the inner atmosphere layer of the defense system. After two successful trials as an interceptor missile, DRDO later developed the AAD missile into a new surface-to-air missile with an extended range (150 km).
On 15 March 2010, a test of an AAD interceptor missile from the coast of Orissa was aborted as a target, a Prithvi missile launched from a mobile launcher from the Integrated Test Complex 3 at Chandipur-On-Sea, veered off course and fell into the sea. The AAD missile to intercept the target was at an altitude of 15 to 20 km above the sea. On July 26, 2010, AAD tested successfully from the Integrated Test Scope (ITR) on Wheeler Island.
On 6 March 2011, India successfully test-fired its interceptor missile from the coast of Orissa, which destroyed a ballistic missile, a modified Prithvi, at an altitude of 16 km over the Bay of Bengal. An AAD interceptor stationed at Wheeler Island, about 70 km across the sea from Chandipur, received signals from tracking radars installed along the shoreline as it thundered the sky at a speed of Mach 4.5 and successfully destroyed the target. On February 10, 2012, AAD was successfully tested again from Wheeler Island. Although successful, these experiments were conducted under laboratory conditions.
The missile defense system in the second stage is based on the AD-1 and AD-2 interceptor missiles that are developed recently in 2019. The second stage of interceptors will be hypersonic with speeds of Mach 6 to 7. The missiles have less time to intercept. The steering systems are more active and able to respond faster.
On 24 September 2020 successful test flight of AAD was conducted. It is the latest test of AAD system and it is expected to be inducted in service of Indian Army by the end of 2020 or in 2021.
These interceptors are capable of intercepting missiles with a range of more than 5,000 km, which follows a completely different path than a missile with a range of 2,000 km or less. During their final stage, ICBMs are propelled toward their targets at speeds twice the speed of ICBMs. The Indian system for each unit costs between US $ 25-20 million.
The development of the AAD system was started in late 1998. Talking about the specification of AAD system it is a single-stage engine with solid propellant. Its first test was conducted in December 2007 and it is expected that it will be inducted into the service of Indian military till last 2020 or in 2021. The length of this Missile is 7.5 meters and its diameter is 0.5 meter. The Missile has a weight of 1.5 ton and it can cruise at a speed of Mach 6 to Mach 7. There are only four or five missiles have been produced by DRDO but only for test purpose.
