The foremast was of a new tripod design that was considerably reinforced to allow the AN/SPS-6 air-search radar system to be replaced with the [[AN/SPS-49]] radar set (which also augmented the existing navigation capabilities on the battleships), and the AN/SPS-8 surface-search radar set was replaced by the [[AN/SPS-67]] search radar. The new mast also incorporates a Tactical Air Navigation System ([[TACAN]]) antenna.<ref name="Stillwell 62.1" /> The aft mast was changed to be placed in front of the aft funnel and mounts a circular SATCOM antenna while another one was mounted on the fire control mast.<ref>Miano 2021, p. 15</ref> By the Korean War, jet engines had replaced propellers on aircraft, which severely limited the ability of the 20 mm and 40 mm AA batteries and their gun systems to track and shoot down enemy planes. Consequently, the AA guns and their associated fire-control systems were removed when reactivated. ''New Jersey'' received this treatment in 1967, and the others followed in their 1980s modernizations. In the 1980s, each ship also received a quartet of Phalanx CIWS mounts which made use of a radar system to locate incoming enemy projectiles and destroy them with a 20 mm Gatling gun before they could strike the ship.{{sfn|Sharpe|1991|p=732}}<ref name="Stillwell 62.2">Stillwell, p. 304.{{Incomplete short citation|date=November 2020}}<!--Ambiguous, there are two Stillwells (1986, 1996) cited in article--></ref> [[File:Pioneer Unmanned Aerial Vehicle.jpg|thumb|alt=A large airborne machine photographed in flight from the ground looking up.

To fire the Harpoon anti-ship missiles, the battleships were equipped with the SWG-1 fire-control system, and to fire the Tomahawk missiles the battleships used either the SWG-2 or SWG-3 fire-control system. In addition to these offensive-weapon systems, the battleships were outfitted with the [[AN/SLQ-25 Nixie]] to be used as a lure against enemy torpedoes; an [[AN/SLQ-32 Electronic Warfare Suite|SLQ-32]] electronic warfare system that can detect, jam, and deceive an opponent's radar; and a [[Mark 36 SRBOC]] system to fire [[Chaff (countermeasure)|chaff]] rockets intended to confuse enemy missiles.{{sfn|Sharpe|1991|p=732}}<ref name="Stillwell 62.2" /> Aside from the electronics added for weaponry control, all four battleships were outfitted with a communications suite used by both cruisers and guided missile cruisers in service at the time.{{sfn|Polmar|2001|p=128}} This communication suite included the OE-82 antenna for satellite communications{{sfn|Sumrall|1988|p=122}} but did not include the [[Naval Tactical Data System]].{{sfn|Polmar|2001|p=128}}
