When people use radar, they are usually trying to accomplish one of three things: Detect objects: Usually, the object is moving, like an airplane being detected by air traffic controllers, but radar can also be used to detect stationary objects buried underground. In some cases, radar's targe...
People who noticed it are bothered to varying degrees, with some experiencing a mild feeling of irritation, while others report sleep disturbances, dizziness and nosebleeds. Conspiracy theorists suggest that it's caused by some sort of secret military communications system used to contact submarines,...
Whenever any suspicious leaks or odors are detected, workers use radiation and chemical test kits to check the levels in the air. USAR teams are recommended to have at least three different visual search devices in their cache. Teams use snake-eye and fiber optic camera systems to get into ...
Indicator Loops are long lengths of cable laid on the seafloor of harbours to detect enemy submarines. They were developed by the Royal Navy in the early 1900s and first trialled at the end of WW1. They were then successfully deployed in WW2 in British ports both at home, in the ...
U-boats were being sunk after surfacing in the dark of night to recharge their batteries. (The charging generators were run by an internal-combustion engine, which required air.) The Germans couldn’t explain it. Did the Allies have a new type of unknown radar that could detect submarines?
11 In the past two years, this market segment has seen a rise in the number of new players because it offers a competitive entry point with products that are much smaller than manned warships and submarines. The in-service fleet of unmanned naval systems...
If you think nuclear-powered submarines or aircraft carriers are rare military assets, then consider heavy bombers: today, only three countries—Russia, the United States and China—operate any at all. The People’s Liberation Army Air Force (PLAAF) likely has 210-230 H-6s in service (not...
They detected around27,000barrels. Over two weeks in March, scientists with NOAA and the Scripps Institution of Oceanography dropped two autonomous underwater vehicles (they look like small submarines) into the ocean, approximately 12 miles off the coast. The researchers knew barrels holding waste ...
Similarly to hospitals or submarines on Earth, these will have an artificial atmosphere, air filtration, controlled temperature, moisture, etc. which usually results in high microbial diversity. The high radiation exposure and microgravity environment will cause (un)expected changes in all living ...
China boasts between 50 and 75 ICBMs and four missile submarines, with a total of eight to nine planned. The country maintains a fleet of 20 nuclear-capable H-6 bombers, but these lack a nuclear gravity bomb. A future bomber, the Xi’an H-20, might eventually be armed with a nuclea...
