New Threat Upgrade

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.

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).

[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.

[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 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.
