The Aegis Weapon System is the world’s most capable naval defense system and the sea-based element of the United States’ Ballistic Missile Defense System. The Aegis Weapon System can simultaneously attack land targets, submarines and surface ships, while automatically implementing defenses to protect the fleet against aircraft and missiles.

The Joint Direct Attack Munitions (JDAM) is a guidance kit that converts unguided bombs, or "dumb bombs" into all-weather "smart" munitions. JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles (28 km).

An airborne early warning and control (AEW&C) system is an airborne radar system designed to detect aircraft. Used at a high altitude, the radars allow the operators to distinguish between friendly and hostile aircraft hundreds of miles away. AEW&C aircraft are used for defensive and offensive air operations. The system is used offensively to direct fighters to their target locations, and defensively to counter attacks. It can also be used to carry out surveillance, and C2BM (command and control, battle management) functions

The Lockheed Martin/Boeing F-22 Raptor is a single-seat, twin-engine fifth-generation super maneuverable fighter aircraft that uses stealth technology. It was designed primarily as an air superiority fighter, but has additional capabilities that include ground attack, electronic warfare, and signals intelligence roles.

The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, fifth generation multirole fighters under development to perform ground attack, reconnaissance, and air defense missions with stealth capability. The F-35 has three main models; one is a conventional takeoff and landing variant, the second is a short take off and vertical-landing variant, and the third is a carrier-based variant.
