Let's kick this DOD weapons test into high gear! Go Big or go home! Yowzer Baby!

Defeating a Russian MIRV (Multiple Independently-targetable Reentry Vehicle) ICBM is an incredibly challenging task, requiring advanced missile defense systems capable of intercepting both the delivery vehicle and multiple warheads at high speeds in space or the atmosphere. The following systems are designed to counter ICBM threats:
1. Ground-Based Midcourse Defense (GMD)
Operated by the U.S., the GMD system uses Ground-Based Interceptors (GBIs) to target ICBMs during their midcourse phase in space.
Each GBI deploys an Exoatmospheric Kill Vehicle (EKV) to destroy the warhead via kinetic impact.
2. Aegis Ballistic Missile Defense (BMD)
Equipped with SM-3 interceptors, this ship-based system targets missiles in the midcourse phase.
The Aegis system may also assist in the terminal phase with SM-6 missiles for lower-altitude interceptions.
3. THAAD (Terminal High Altitude Area Defense)
Designed to intercept short- to intermediate-range ballistic missiles, THAAD may have limited utility against ICBM warheads in their terminal phase.
4. Next-Generation Interceptors (NGI)
Under development to replace GMD interceptors, NGIs are expected to handle advanced threats like MIRVs and hypersonic glide vehicles.
5. Patriot PAC-3 and other terminal systems
These systems provide a last line of defense but are primarily effective against shorter-range ballistic missile threats.
Key Challenges:
Decoys and Countermeasures: Russian MIRVs often deploy decoys and penetration aids to overwhelm defenses.
Speed and Accuracy: ICBMs travel at speeds exceeding 20,000 km/h, requiring interceptors to respond with extreme precision.
Layered Defense: Success typically depends on a combination of midcourse and terminal interception systems, creating a layered defense.
No system guarantees 100% success against a sophisticated MIRV ICBM attack, but ongoing developments aim to improve interception probabilities.
Note: Maybe the best way to defeat an incoming MIRV ICBM is via an orbital kinetic energy weapons platform. Orbiting laser (projected energy beam) systems such as the U.S.'s Merlin and the UK's Dragon Fire may work as well, but only while the ICBM is executing its midcourse exoatmospheric phase in space.
