I'll throw in my old ship into this argument:
U.S.S. Long Beach (CGN-9). The world's first Nuclear-powered surface vessel. She also featured the first phased-array radar and the most impressive arsenal of her time. During Vietnam, she was the first warship to shoot down an aircraft with a Surface-to-Air missile in combat. Decommisioned in 1994, she was the first, and arguably the greatest of all American nuclear-powered cruisers. At the time of her commissioning she was armed as follows:
2 - Mk 10 Terrier Surface to Air missile launchers (Mod 0 and Mod 1 - Mod 0 held 40 missiles while Mod 1 held 80).
1 - Talos Surface to Air missile system (it was this system that shot down a North Vietmanese Mig)
1 - Asroc anti-submarine rocket launcher
2 - 354 mm anti-submarine torpedo tubes
Shortly after commissioning, 2 Mk. 30 5"38 caliber gun mounts were added midships.
In 1980 she underwent refueling and NTU upgrade. Her final armaments were:
2 - Mk 10 SM2-ER SAM systems. 120 round magazine. Each missile capable of ranges up to 125 miles. Could handle up to 16 missiles in the air at any time.
2 - 5"38 caliber dual-purpose gun mounts
1 - Asroc anti-sub rocket launcher
2 - 354 mm anti-submarine torpedo tubes
8 - Harpoon anti-ship missiles
2 - Tomahawk Armored box launchers (capable of holding up to 8 Tomahawk cruise missiles)
2 - Phalanx point defense systems.
She also featured flag facilities that rivaled any onboard a carrier as well as electronic warfare detection and intercept capabilities far beyond most cruisers. For sheer amount of weaponry, only the Aegis cruisers could challenge her and she repeatedly outperformed them in every operations exercise that she participated.
Only part of that was thanks the to the excellent crew...
