Nuclear test "John". (Nevada test site 19. July 1957)


Kimmo Huosionmaa

One of the most bizarre military tests was nuclear test code-named "John". The test was part of the nuclear test series of "Operation Blumbbob", and it was accomplished in the Nevada desert in 19. July 1957. The test was the first time when the United States Air Force tested the nuclear warhead in an air-combat missile. The AIR-2 "Genie" was the first but not an only air-to-air rocket, what has the 2 kilotons nuclear warhead. That rocket was installed under the F-102 Delta Dart and F-4 Phantom fighters, during the cold war.

Nuclear test "John" was very scary because the group of men was standing just under the explosion, and the idea was tested, would that kind of explosion cause blindness and cancer.  The idea was also tested, how close of the target was safe to use nuclear weapons. This type of tests would not be made in modern times, but the attitudes in the 1950's were different than today. "John" was a very interesting thing, because the weapon itself carried by T-38 "Talon" aircraft and the reason why this test was made, was to test the installation of nuclear missiles also in other aircraft than the first line high-speed jet fighters.

There were a couple of things, what the Atomic energy commission didn't mention about the test. If "John" were successful would the nuclear weapons installed also in the high-speed jet fighters, and those warheads would be effective also against ground targets. So the plan was to create the multimission weapon, what can be used against every military target in the world. That weapon can destroy incoming bombers, tank or other military formations, warships and factories. But the high-altitude test was also made for testing the ABM-system.

AIR-2 was an effective plan for the fast-moving system, what can move with extremely high speed to some area. And then it can be launched to the route of incoming missiles.  The warhead would be detonated in the near- or middle of the missile swarm. And the radiation would destroy the electronics of those warheads.


That weapon was retired from service in the 1990's but it was showing the route to the more effective ASAT and ABM-weapons like SRAM and ASAT. Actually, every satellite launching vehicle can be modified for a nuclear missile. Those air-launched carrying vehicles, what are under development in many countries are multipurpose productions, what can be equipped with the warhead. SRAM-missiles have officially removed from SAC inventory because they are classified as the offensive nuclear weapons, and they wanted to replace with some conventional solution, what is not so dangerous in the wrong hands.

The ASAT-missile can be installed under the F-15 and the project was shut down because of the problems of aiming the kinetic energy impact warhead but creating that kind of weapons continue. But we know that the SRAM-missiles can be used in the same missions with ASAT. The kinetic energy version of this missile is the multipurpose weapon, what is normally installed in B-52 bombers, and it can shoot against satellites. That aircraft has also used for carrying "Hound Dog" missiles, what are actually modified Pegasus-rockets, what are equipped with nuclear- or kinetic warheads.

The new 3D printers are coin-size systems.

"The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation. Credit: Sampson Wilcox, RLE" (Scitech, Tiny Titan: MIT’s Revolutionary Coin-Sized 3D Printer Fits in Your Pocket) Researchers created a 3D printer that is coin-size. That kind of printer can create things like microchips. But it's possible. Those tiny 3D printers can also work in extremely large-size projects. In simplest models, the 3D printers are positioned on tracks. The 3D printer itself is the tool, that can be part of the modular production systems.  There are visions of high-temperature metal printers installed on the gantry cranes. That makes those crane printers that can make even ship-size things. The crane that the printer controls can move back and forth and the printer can move horizontally. This kind of thing can turn the crane into a high-temperature 3D printer, that...

Quantum computers and ultra-fast photonic microchips can danger even the most secure communication.

"Quantum computers could pose a major security risk to current communication systems in 12-15 years with their exponentially greater speed and code-breaking ability. (ScitechDaily, Today’s Most-Secure Communications Threatened by Future Quantum Computers) Quantum computers can break entire binary cryptography. And that makes all communication unsecured. That is one of the greatest threats in quantum computing. And this brings the arms race to the quantum age. The quantum computer can create codes that any binary computer can break. But the quantum computer can also break old-fashioned codes. And that makes it an ultimate weapon and sabotage tool.   Quantum computers can change the measurements of the ammunition in factories by changing the system calibration. Or it can delete databases from the opponent's computer systems. This thing can delete all SIM cards from mobile telephones. In peacetime, the hackers that operate using quantum systems can steal the names of the counter-...

Electric power innovations. Fuel cells in aircraft and solar panels over Arizona canal.

  "ZEROe teams powered on the iron pod, the future hydrogen-propulsion system designed for Airbus’ electric concept aircraft." (Intersting Engineering, Airbus's ZEROe: First engine fuel cell powers up for hydrogen flight) Electric power innovations. Fuel cells in aircraft and solar panels over Arizona canal.  Airbus Zero is a testbed for fuel cells that are used in commercial aircraft. The problem with aircraft is always noise and pollution. If the aircraft uses electric engines. That decreases noise levels and cleans the air, especially around airfields. Lightweight solar panels that can be installed on the wings and body of aircraft can give electricity to electric engines. And they can extend an aircraft's operational range.   The thing that makes this kind of system interesting is that the "flying cars" or cheap VTOL aircraft can use them as a power source. The hydrogen power cells can give energy to electric aircraft at night time. And that makes them m...
