Block IIIF satellites host a redesigned U.S. Nuclear Detonation Detection System (USNDS) capability that is both smaller and lighter than previous systems. [ 11 ] The USNDS is a worldwide system of space-based sensors and ground processing equipment designed to detect, identify, locate, characterize, and report nuclear detonations in the Earth ...
In the 1970s, the nuclear detection mission was taken over by the Defense Support Program (DSP) satellites. In the late 1980s, it was augmented by the Navstar Global Positioning System (GPS) satellites. The program is now called the Integrated Operational NuDet (Nuclear Detonation) Detection System .
A nuclear detonation detection system (NDDS) is a device or a series of devices that are able to indicate, and pinpoint a nuclear explosion has occurred as well as the direction of the explosion. The main purpose of these devices or systems was to verify compliance of countries that signed nuclear treaties such as the Partial Test Ban treaty of ...
In the article astrophysicist Ed Fenimore states "Vela was the prototypical project that made Los Alamos the premier scientific national security laboratory in the world." Data from Project Vela is still used for national security work, and sensors, such as those developed in the project, are still an important part of nuclear detonation detection.
ROC post bomb detection instruments (see Bomb Power Indicator) operated by recording the peak overpressure of the blast wave from any nearby nuclear explosion. Any ultra-high-altitude nuclear explosion, designed to knock out the UK's communications and electronic equipment would not produce a detectable blast wave, and the AWDREY system was ...
The GE 477L Nuclear Detection and Reporting System (NUDETS, [1] NUDETS 477L, [2] Program 477L [citation needed]) was a Cold War "Nuclear Detonation and Radioactive Fall-out Reporting System" for the National Military Command System. [3] Planning/development began "by September 1, 1959, when NORAD had taken over responsibility from CONAD."
The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
