Statements 1 and 2 are correct. Israel’s Iron Dome is based on the principle of kinetic interception which is based on the method of destroying a threat by physically striking it with another object.

It works by firing an interceptor missile that is specifically designed to collide with and destroy the incoming projectile. The interceptor is guided by radar and other sensors, which track the trajectory of the incoming threat and help the Iron Dome system calculate the most effective intercept point. The key benefit of kinetic interception is that it doesn’t rely on any sort of explosive payload – it’s all about the direct impact.

Project Kusha is a mission by India’s Defence Research and Development Organization (DRDO) to develop a state-of-the-art air defense system similar to Israel’s Iron Dome. The project aims to develop an indigenous long-range air defense system that can detect and destroy enemy projectiles and armor, including cruise missiles, stealth fighter jets, and drones at long range.

It seeks to establish a formidable three-layered defense system with the capability to neutralize enemy aircraft and missiles from extended distances effectively.
