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

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.

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:

Operation DOMINIC Johnston Island (1962), Section 3

Thor missiles were built by Douglas Aircraft Company -- later merged into McDonnell Douglas in 1967, and then Boeing in 1997 -- and required manufacturer technicians to monitor their technical operation.

DOMINIC I nearly ran out of Thor rockets, because of unforeseen tracking and rocket component failures. FISHBOWL reached completion with a Nike-Hercules rocket in the last shot, coded as Tightrope.

Instrument pods replaced AVCO reentry vehicles after aerodynamic failures in trial launches. Ceramic plating protected the lower rocket from exhaust eddies created by the pods and their support extensions.

Sadly obvious, not much could be done with the dark areas with digital processing, without increasing defects.

The shoreline cliffs and beach rocks are grey-black basalt.

Scientific monitoring of high altitude nuclear bursts took place at stations like these throughout the Pacific basin.

Flag Plot on the USS Princeton (LPH-5) was the VIP work center of the fleet. This is normally the fleet commander's navigation and operations office, but Major General Alfred Starbird was the joint task force leader of DOMINIC I. (R to L) Dr. William E. Ogle, Los Alamos test director (a.k.a. supreme scientific commander, who also was among the top American negotiators for the use of Christmas Island/Kiritimati during DOMINIC); Starbird, Joint Task Force 8 supreme commander, US Army; Captain Paul J. Knapp, USN, skipper of USS Princeton; Lieutenant Colonel George Kallis, USAF, JTF 8 technical operations deputy; unknown US Navy commander.

MIM-14 (Mobile Interceptor Missile design 14) Nike-Hercules launch in salvo, each capable of reaching over 100 000 feet (30.5 km). This was the type of missile that carried the W31 boosted fission nuclear warhead of the last shot of the entire operation, coded as Tightrope, to 13 miles (21 km) in altitude.

Instrument stations were placed throughout the Pacific basin.

Rafts like these were the bombing targets for nuclear weapons development tests off of Johnston Island, over open sea. Targeting radar reflectors, radio beacons, and flashing lights made them easy to find.

USS Princeton (LPH-5) hosted the fleet command center for some of Operation DOMINIC I. The darker, greyish-blue water under the ship was a sea rise, likely of coral.

Highly radioactive filter paper from a shot sampling mission was loaded into the lead protection casing, called a pig. That Martin B-57 flew through a mushroom cloud to extract bomb debris particles, using filter pods along the wing tips. These samples were flown directly to the Lawrence-Livermore and Los Alamos weapons labs, for fission efficiency analysis.

The relative amount of unfissioned uranium and plutonium among their decay products determined the yield of the fission component. Fireball photography and electromagnetic signal timings between fission and fusion stages were common techniques to calculate the fusion and total yields.

USS Spruance (DD-447) sailed at sea after its FRAM II (Fleet Rehabilitation And Modernization, Mark II) upgrade during 1961 in Hawaii. Mark II was a lighter upgrade intended to extend the useful life of the World War II ship by at least 5 years, and less costly than a Mark I system, with the Vietnamese insurgency growing. The overhaul included the new DASH (Drone Anti-Submarine Helicopter) system, Mark 32 torpedo tubes, and VDS (Variable Depth Sonar), to detect extremely quiet submarines.
