The superiority of the American military submarine will soon be threatened if it does not get funds in time to replace old vessels. One of America’s biggest threats to foreign countries, is a submarine that is 171 meters long, its height is like a four-story building, can fully dive beneath the surface of the water and can roam the sea unnoticed. The Ohio class SSBN submarine carrying the Trident II nuclear missile by Defense Minister Ash Carter this week is called “really important” and “the source of American excellence”. SSBN submarines strategically placed around the world carry dozens of ballistic missiles that can shoot 7400 kilometers away. “This is the most important weapon system that belongs to America regarding strategic security because no one knows where it is, always active and constantly alert,” said lead engineer sonar Jarrad Hampton on Hampton Roads.
Officials say the submarines are one of the most important parts of America’s nuclear arsenal, a term used to describe America’s ability to launch nuclear attacks from air, land or sea. But that capability will soon be threatened if it does not get funds in time to replace old vessels. The walls of the submarines can only last about 40 years. NASA’s Langley Research Center in Hampton, Virginia, will conduct a test by swinging the body of a Sea Knight CH-46 helicopter like a pendulum, then dropped from a height of about 10 meters to the ground. NASA engineers will intentionally drop an American Marine helicopter, which is equipped with a floor base of various composite materials, to see how far the strength of the aircraft frame made of these materials can protect anyone who is in the cabin.
According to the space exploration agency, there is increasing interest in the framework of aircraft made of carbon, but not many safety tests have been carried out at the scale of the scale to determine the accident resistance. NASA’s Langley Research Center in Hampton, Virginia will conduct a test by swinging the body of a Sea Knight CH-46 helicopter like a pendulum, then dropped from a height of about 10 meters to the ground. The helicopter will crash to the ground at a speed of about 50 kilometers per hour. NASA officials say the situation after the fall will be severe but the humans inside can survive, according to civilian and military requirements.
