- AEGIS battle management system : An integrated system of computers, radars, and other systems that provides integrated management of a shipboard suite of strategic strike, anti-surface warfare, ballistic missile defense and anti-air warfare principally using missiles in vertical launch systems; it complements other integrated systems for anti-submarine warfare and naval gunfire support
- Ballistic missile defense : A combination of sensors, command and control systems, and missile/warhead kill mechanisms that protect a region, or, in the case of the U.S., theaters of operations as well as the nation proper.
- RIM-161 Standard SM-3 : Theater anti-ballistic (i.e., midcourse and terminal phases) and anti-satellite missile, using hit-to-kill, launched from ships equipped with the AN/SPY-2 radar and AEGIS battle management system.
- Burke class destroyer : Large U.S. Navy multirole destroyers equipped with AEGIS battle management system and constant upgrades; Japan has Kongo-class clones, also being upgraded to ballistic missile defense; South Korea has the KDK-class
- Kongo-class : Destroyers currently in service with the Japanese Maritime Self-Defense Force (i.e., Japanese Navy), which are licensed copies of the U.S. Burke-class and are being upgraded for ballistic missile defense
- AN/SPY-1 : This is the main radar for the air and cruise missile defense functions of the AEGIS battle management system aboard cruisers and destroyers
- Ticonderoga class cruiser : Modern U.S. Navy cruisers usually serving as carrier or amphibious escorts, but capable of independent action including long-range strike, anti-air/anti-ballistic missile/anti-satellite warfare, naval gunfire support, and antisubmarine warfare.
- AN/TPY-2 : A long-range, high-altitude X-band phased array radar for use to guide the top layer anti-ballistic missiles (i.e., THAAD) of a theater ballistic missile defense system, cueing for lower-altitude system, and as a component of national missile defense
