{{USS|Mahan|DDG-42}} was selected to install and test the Terrier New Threat Upgrade (NTU) Combat System with the improved Standard Missile Two Block II (Extended Range). Testing lasted from October 1981- March 1985. New Threat Upgrade allowed the full use of newer [[Standard missile]]s (SM-2) and improved the interoperability of the radar and computer systems aboard the ships. The system allows the ships to which it was fitted to time share illumination radars for multiple missile interceptions in a manner similar to the [[Aegis Combat System]]. Some sources claimed that NTU ships were superior in some respects to [[Aegis combat system|Aegis]] ships of the same era, particularly in the area of [[user interface]]. They were inferior in that they could not deal with a [[Saturation attack|saturation missile attack]] as well as Aegis vessels. The lower levels of funding available to the USN after the Cold War lead to most of the NTU ships being retired early, because of high cost of operation compared to newer vessels. As a result, the [[United States Navy]] no longer fields any NTU capable ships and most newly constructed ships have the [[Aegis weapon system]].

==History==
The New Threat Upgrade to the [[Leahy class cruiser|''Leahy'' class]] included massive remodeling of the ship from food service space rehabilitation to a main propulsion system overhaul.<ref>[http://www.globalsecurity.org/military/systems/ship/cg-16.htm]</ref> Entire systems were removed and replaced, for example the [[AN/SPS-40]] air-search radar was replaced with the [[AN/SPS-49]] air-search radar. The upgrade was also quite expensive and the ships modified didn't serve much longer after the modification. For example, [[USS Gridley (DLG-21)|USS ''Gridley'' (CG-21)]] received NTU in 1991 at a cost of $55 million but was decommissioned in early 1994.

In 1983, the USS Mahan (DDG-42) was underway to test and evaluate the Terrier New Threat Upgrade (NTU) Combat System.

New Threat Upgrade (NTU) was a United States Navy program to improve and modernize the capability of existing cruisers and destroyers equipped with Terrier and Tartar anti-aircraft systems, keeping them in service longer.

The Program[edit]

USS Mahan (DDG-42) was selected to install and test the Terrier New Threat Upgrade (NTU) Combat System with the improved Standard Missile Two Block II (Extended Range). Testing lasted from October 1981- March 1985.[1]

New Threat Upgrade allowed the full use of newer Standard missiles (SM-2ER BlkII w/Mk80 booster) and improved the interoperability of the radar, computer, tracking and engagement systems aboard the ships.[citation needed] The system allows the ships to which it was fitted to time share illumination radars for multiple missile interceptions in a manner similar the Aegis Combat System.[2][3]

History[edit]

The New Threat Upgrade to the Leahy class included massive remodeling of the ship from food service space rehabilitation to a main propulsion system overhaul.[4] Entire systems were removed and replaced, for example the AN/SPS-40 air-search radar was replaced with the AN/SPS-49 air-search radar.[5]

In 1988–90, the Kidd-class destroyers received the New Threat Upgrade, including a new superstructure and heavier mainmast cooperative engagement with Aegis Ticonderoga-class cruisers, which could control the Kidds’ surface-to-air missiles while they remained electronically silent.[citation needed] The Spruance class, the predecessor to and close relative of the Kidd-class, did not receive the NTU.[citation needed][6][7]

End of NTU[edit]

The Cold War ended shortly after the New Threat Upgrade was initiated. The lower levels of funding available to the United States Navy after the Cold War meant that the NTU upgrade was never applied to all of the intended vessels.[citation needed] The NTU upgrade itself was expensive.[citation needed] Many of these ships were retired in the 1990s whether they received the full NTU modification or not; most of these warships built in the 1960s-1970s had high operational costs and manpower requirements (especially those which were nuclear-powered), compared to newer Aegis warships.[citation needed] The USS Texas (CGN-39) was decommissioned during the upgrade, in the midst of her reactor refueling. USS Gridley (CG-21) received NTU in 1991 at a cost of $55 million but was decommissioned in early 1994. Overall, all US Navy ships that received the NTU upgrades were decommissioned within six years of their upgrade, as the Navy chose instead to order new ships with the Aegis weapon system.[citation needed]

The Navy also accelerated the retirement of the Spruance and Kidd classes, despite their recent modifications, due to the arrival of the Aegis-equipped Arleigh Burke-class destroyers, which were more effective and cost-efficient.[citation needed] The four Kidd destroyers were later transferred to Taiwan (Republic of China) where they remain in service, while some members of the Spruance class remained in service until 2005.[8]

NTU systems[edit]

  • AN/SPS-49(V)5 - A 2D Air Search Radar (azimuth and range)
  • AN/SPS-48E - A 3D Air Search Radar (azimuth, range and altitude)
  • AN/SYS-2(V)1 Integrated Automatic Detection and Tracking System (IADTS)
  • (A)CDS - (Advanced) Combat Direction System
  • WDS Mk 14 - Weapons Direction System
  • Mk 74 Tartar[9] and Mk 76 Terrier Fire Control Systems (AN/SPG-55B radar for Terrier ships and AN/SPG-51 for Tartar)
  • AN/SYR-1 Communications Tracking Set,[10] used for SM-2 missile downlink
  • Mk 10 twin-arm manual launcher, Mk 13 single-arm automated launcher and Mk 26[11] twin-arm, automated missile launchers
  • RESS - Radar Environmental Simulator System

NTU ships[edit]

These classes had some of their units modified with the New Threat Upgrade.

KDX-II Class[edit]

The Navy of the Republic of Korea uses a NTU derived system for its Chungmugong Yi Sunshin class destroyers.
