The motto in Latin: Custos Custodum Ipsorum means "Guard of the Guardians Themselves" in English. The Aegis ballistic missile defense system (Aegis BMD or ABMD), [1] also known as Sea-Based Midcourse, is a Missile Defense Agency program under the United States Department of Defense developed to provide missile defense against short and intermediate-range ballistic missiles.
Diagram of the Aegis Combat System (Baseline 2-6). The Aegis Combat System (ACS) implements advanced command and control (command and decision, or C&D, in Aegis parlance). It is composed of the Aegis Weapon System (AWS), the fast-reaction component of the Aegis Anti-Aircraft Warfare (AAW) capability, along with the Phalanx Close In Weapon System (CIWS), and the Mark 41 Vertical Launch System
Since the mid-2000s, they have also been equipped with a missile defense capability with the primary intention of countering North Korean ballistic missiles, and now have an Aegis BMD 3.6 system installed to launch SM-3 Block IA and IB missiles. [1] The Mark 41 Vertical Launching System arrangement, similar to the Arleigh Burke class, consisted ...
Phase Four (in the 2020 timeframe) – After development and testing are complete, deploy the SM-3 Block IIB to help better cope with medium- and intermediate-range missiles and the potential future ICBM threat to the United States. The deployment of warships equipped with the Aegis RIM-161 SM-3 missile began after Obama's speech in September 2009.
In May 2014, USNI News reported that 21 of the 28 Flight I and II Arleigh Burke-class destroyers would not receive the full mid-life upgrade that included electronics and Aegis Baseline 9 software for SM-6 compatibility; instead, they would retain the basic BMD 3.6.1 software in a $170 million upgrade concentrating on HM&E systems, and on some ...

The 5"/54 caliber or 5"/62 caliber Mark 45 gun is fully-automated and capable of engaging surface targets in an anti-ship role, air targets in an anti-aircraft or defensive anti-missile role, and land targets in a naval gunfire support role. The gun has a range of 13 nmi (24.1 km) for 5"/54 variants [4] or 20 nmi (37.0 km) for the 5"/62 variant ...
The GMD can also work to receive information from the C2BMC, which allows Aegis SPY-1, and TPY-2 to contribute to the defense system. [17] A problem with GMD is that the ground systems have increasingly becoming obsolete as the technology was initially installed as early as the 1990s. So, the ground sensors had been replaced sometime in 2018.
