Part of the New Threat Upgrade are significant improvements to SPS 48 radar: SPS 48E radar modification provides higher elevation angle coverage, increased average power output and provides frequency and pattern flexibility to defeat jamming while detecting targets through heavy clutter. Also included is the addition of the SYS 2 integrated automatic detection and tracking system that integrates outputs of SPS 48 and 40 air search radars to provide a correlated track file.

VIRGINIA

(Scale 1 : 1 800)

VIRGINIA

Sonars: EDO/GE SQS 53A; bow-mounted; active search and attack; medium frequency. Based on SQS 26 but with digital computers

Programmes: Virginia was authorised in FY 1970, Texas in FY 1971, Mississippi in FY 1972, and Arkansas in FY 1975, Originally classified as guided missile frigates (DLGN); subsequently reclassified as guided missile cruisers (CGN) on 30 June 1975.

Modernisation: Standard SM-1 MR replaced bySM-2MR using Block II missiles to counter current and protected anti-ship cruise missile threats at extended ranges in the presence of severe enemy electronic countermeasures. Production systems were deployed in all guided-missile cruisers and in "DDG 993" class destroyers in FY 1988. The initial phase of fleet introduction of SM-2 in a Tartar ship was completed in May 1986 in Virginia. Tomahawk fitted in all of the class at the expense of the helicopter capability. Structure: The principal differences between the "Virginia" and “California" classes are the provision of improvements to anti-air warfare capability, electronic warfare equipment, and anti-submarine fire control system. The deletion of the separate ASROCMk16 launcher permitted the "Virginia" class to be 1 1 ft shorter.

A hangar for helicopters was installed beneath the fantail flight-deck with a telescoping hatch cover and an electromechanical elevator provided to transport helicopters between the main deck and hangar; the installation of Tomahawk right aft meant the removal of helicopter facilities.
