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 ...
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 ...
Vela started out as a small budget research program in 1959. It ended 26 years later as a successful, cost-effective military space system, which also provided scientific data on natural sources of space radiation. In the 1970s, the nuclear detection mission was taken over by the Defense Support Program (DSP) satellites.
In the late 1940s, the United States began to develop the capability to detect atmospheric testing using air sampling; this system was able to detect the first Soviet test in 1949. [30] Over the next decade, this system was improved, and a network of seismic monitoring stations was established to detect underground tests. [ 30 ]
The United States is continuing to plan for a nuclear detonation in a major city -- should it occur near you, here's what you should do. If a nuclear bomb goes off, this is the most important ...
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."
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.
Project Mogul (sometimes referred to as Operation Mogul) was a top secret project by the US Army Air Forces involving microphones flown on high-altitude balloons, whose primary purpose was long-distance detection of sound waves generated by Soviet atomic bomb tests. The project was carried out from 1947 until early 1949.
