Comparison of anti-ballistic missile systems

This is a table of the most widespread or notable anti-ballistic missile (ABM) systems intended in whole or part to counter ballistic missiles. Since many systems have developed in stages or have many iterations or upgrades, only the most notable versions are described. Such systems are typically highly integrated with radar and guidance systems, so the emphasis is chiefly on system capability rather than the specific missile employed. For example, David's Sling is a system that employs the Stunner missile.
