India is trying novel ways to safeguard itself from assaults from its neighbours. If China and Pakistan execute missile attacks on India, there will be consequences. The government is presently developing an indigenous Variant to Russia's S-400. This weapon is classified as a Long Range Surface to Air Missile (LRSAM), and its design is overseen by the Defence Research and Development Organisation (DRDO).

The country is now armed with S-400 missile defence systems, which were purchased from Russia and are widely considered as the world's most advanced missile defence system. Pathankot, near the Pakistani border, and Siliguri, near the Chinese border, both have S-400 deployments. The DRDO is developing a new indigenous 'Long Range Surface To Air Missile' defence system that will be faster, more precise, and technologically advanced than the S-400. The DRDO is developing an indigenous air defence system capable of hitting long-range targets. The ability to engage and destroy opposing fighter aircraft, ballistic missiles, and attack drones while in the air is one of the LRSAM's capabilities. The LRSAM will be a three-tiered system with missiles ranging in range from the ground to the air.
These missiles are designed to kill hostile aircraft flying at different altitudes and distances across the sky. The indigenous LRSAM is expected to have a range comparable to the S-400, which can reach up to 400 kilometres. It, like the S-400, will be able to intercept hostile missiles in the sky. The LRSAM system will provide multi-layered defence against enemy aircraft arriving from a variety of angles. This ambitious project, valued at more than $2.5 billion, aspires to position India in an exclusive club of nations with indigenous capability to destroy enemy assets in the air at such great distances.
The collaboration between India and Israel in the development of the medium-range surface-to-air missile system (MRSAM), capable of targeting aerial threats at distances of 70 kilometres or more, has provided a firm basis for this cutting-edge endeavour. India hopes to improve its defence capabilities by developing the LRSAM in-house, boosting self-reliance, and bolstering national security against prospective aerial attacks.
