New Threat Upgrade
Vessels of the California class cruisers, Virginia class cruisers and Kidd class destroyers had their Tartar systems upgraded to modification 14 or 15 standard which enabled them to employ the Standard missile 2 as part of the New Threat Upgrade(NTU) program. The New Threat Upgrade equipped vessels could utilize the inertial guidance systems on the SM-2 and time share illumination radars for semi-active homing in the terminal phase of the intercept, increasing the number of targets the Tartar system could attack at the same time. The New Threat Upgrade Tartar ships could function nearly as well as Aegis Combat System equipped vessels, except for dealing with saturation missile attacks. The NTU still requires the AN/SPG-51 radar to acquire a lock on the target and illuminate it just before intercept.

Famous quotes containing the word threat:
“Where do whites fit in the New Africa? Nowhere, I’m inclined to say ... and I do believe that it is true that even the gentlest and most westernised Africans would like the emotional idea of the continent entirely without the complication of the presence of the white man for a generation or two. But nowhere, as an answer for us whites, is in the same category as remarks like What’s the use of living? in the face of the threat of atomic radiation. We are living; we are in Africa.”
—Nadine Gordimer (b. 1923)
