Aegis Combat System


Description:

The Aegis weapons system is a surface-to-air integrated weapons system. It is designed to defend the fleet against any airborne threat. The heart of the Aegis system is the AN/SPY-1 Phased-array radar system coupled with the AN/UYK-1 high-speed computer system. This combination is able to detect incoming missiles or aircraft, sort them by assigning a threat value, assign on-board Standard surface-to-air missiles, and guide the missiles to their targets. Aegis can track up to 100 targets at any given time. The radar panels are flat structures, mounted to give 360 degree coverage around the ship. These are an improvement over the old rotating type of radar in that there are no moving parts. The old rotating radar covered ONLY the area they were scanning. Phased arrays switch rapidly and cover the entire range around the ship in milliseconds.
--------------------

AEGIS is currently carried aboard 2 types of ships. The TICONDEROGA-class cruisers were the first. These ships are often fitted with 2 MK 41 VLS. They can carry up to 122 missiles of all types, including Tomahawk, Standard and SLAM. These ships carry a "full" AEGIS System.

The above taken from Unofficial US Navy website where the full text can be read.

As can be seen in the attachment above, each of the arrays are of considerable size.

.... so; a lot of array to become misaligned as reported to be the case in the Port Royal grounding.

Towed Array Sonar type AN/SQR-19B (or a variant/successor of/to same)

Not sure what you were reading into the weights Ivor. My intention was to give an indication of the size and weight of the aerial/antenna arrays associated with the AEGIS system.

Can't recall if it was one or more of these arrays that required realignment as a consequence of the Port Royal grounding incident.
