By the way, Long Beach was the first surface ship to use a surface-to-air missile to down an enemy fighter. It shot down a North Vietmanese Mig over the Gulf of Tonkin using the Talos long-range missile system. (Talos was removed from the ship in the early 1980's, being replaced by two Tomahawk armored box launchers. The missile magazine was converted into a very large gym, Tomahawk Control Room, and Ship's store area.)
During the same conversion they converted the forward Mk 10 launchers to the Standard Missile (1) system. They were later upgraded to SM-2 (ER) missiles that could down aircraft or missiles at ranges of up to 125 nautical miles. Harpoon anti-ship missiles were added as well (we fired one of them while I was on board as well, but I can't find the pic of it being launched). Two CIWS weapons were also added on the aft superstructure.
Long Beach, along with Enterprise, also boasted the first phased array radar when originally commissioned. The system was removed in the 70's and replaced with a standard SPS-49/SPS-48 combination. Plans to equip her with Aegis were nixed by congress due to cost.
