VELA UNIFORM playtime with very low resolution source

VELA UNIFORM Participation in Operation NOUGAT and GNOME (1962)

This was an emergency response to the Soviets resuming nuclear testing after the revelation that U-2 spy planes exposed the significant strategic gap in Soviet nuclear missile development. Under way within 2 weeks of the Soviet resumption, these operations were a large mix of expert academics, industry, seismic monitoring organizations, the military, and the Atomic Energy Commission (now the Department of Energy). VELA UNIFORM set to develop means of detecting, identifying, and locating underground nuclear explosives after the looming (atmospheric) Limited Test Ban Treaty took effect by 1963. VELA UNIFORM was the technical working to build on enforcement of future international testing requirements.

The VELA program also had complementary components for detecting, identifying, and locating nuclear tests:

VELA SIERRA, for atmospheric nuclear explosives
VELA HOTEL, detection from space

Random scene frame comparisons:

 Instrument trailers are essential data recording platforms for scientific analysis of each test.

Data capture trailer at GNOME:

Seismometers near ground zero, with signal recordings, required batteries to operate. Using commercial power could be disastrous because of the huge electrical surges that would be generated in long wires by the electromagnetic pulse, even with underground shots. Pulses like these could damage commercial power supplies over a vast area.

Ground shock gauge:

Electromagnetic pulse effects antennas:

Loop antenna resonance optimizes as the antenna loop circumference reaches one wavelength of the source electromagnetic signal.

Oscilloscopes capture weapons signal events in microseconds

Typical nuclear shots involved dozens if not hundreds of individual experiments:

Still photography of ground shock displacement effects was integral with data collection:

This test left a visible subsidence crater:

Shuron Ronsir Zyl ebony frame eyeglasses were among the most iconic designs of the 1960s, dating back to their 1947 development:
