Missile defense refers to a system, weapon, or technology that detects, tracks, intercepts, and destroys attacking missiles. Originally designed to counter nuclear-armed intercontinental ballistic missiles (ICBMs), its use has expanded to include shorter-ranged non-nuclear tactical and theater missiles.
A missile is a guided, airborne, long-range weapon that can fly on its own, typically propelled by a jet engine or rocket motor. Hence, guided missiles or guided rockets are other names for missiles (when a previously unguided rocket is guided).
The five systems that make up a missile are the targeting, guidance, flight, engine, and warhead systems. Surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons are some of the different types of missiles available.
The Global Boost-phase missile defense market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Making Sense of Ballistic Missile Defense: An Assessment of Concepts and Systems for U.S. Boost-Phase Missile Defense in Comparison.The ability to shoot down a missile during its powered phase, when it exhibits a bright plume signature and before it disperses its payload and countermeasures, is one of the main advantages of boost-phase defense that is generally acknowledged.
This allows the target to be destroyed to be identified with great clarity. One of the motivations for the pursuit of boost-phase defense has been the possibility to solve the midcourse discrimination challenge.
The challenge is that, when launch happens, the boost-phase interceptor (BPI) must be in close proximity to a location at which it may intercept the target and must be ready to act quickly. It turns out that saying this than doing it is considerably easier.
Any boost-phase intercept, whether carried out kinetically or by directed energy, must be launched after detection from a platform that is within the range and action time of the interceptor, essentially intercepting before the hostile missile’s “booster cut-off,” which can take as little as a minute for slower-burning liquid-fueled intercontinental ballistic missiles (ICBMs) to complete boost.
Although it seems like a smart idea, boost-phase defense has its own set of difficulties. First of all, the boost-phase schedule for the hostile missile is very condensed, regardless of whether a solid or liquid rocket motor is employed.
In a broad sense, the intercept procedure must first establish whether the launch actually represents a hostile missile and, if so, establish its trajectory. The “kill” vehicle (KV), which performs the “kill” function, must then approach and fire at the target.
