During the christening ceremony of the new US nuclear submarine USS Hyman G. Rickover (SSN 795), a bottle of champagne was only smashed at the third attempt, reports Interfax. & nbsp; It should be noted that the mission was given to the daughter of the former Chief of Staff of the US Navy, Jonathan Greenert. Sarah Greenert hit the side of the sub with the bottle twice, but the container didn't break. The bottle was only broken after the instructions of the military. & nbsp; The incident took place in Groton, Connecticut. The new submarine was built by General Dynamics. Sarah Greenert is his employee. & Nbsp; Traditionally, a bottle of champagne is broken on the hull of a new submarine. Sailors think that an unbreakable bottle is a bad sign for a ship. & nbsp; The Virginia IV-class Hyman G. Rickover (SSN 795) multipurpose nuclear submarine, after entering the US Navy, will carry torpedoes and 12 Tomahawk cruise missiles with a range of 1.6 thousand kilometers. The displacement of the submarine reaches 7.8 thousand tons, and its length is about 115 meters. & nbsp; Previously, it had been reported that the US Army, during testing of the aircraft carrier, caused an earthquake. It was caused by an explosion on the high seas during testing of the USS Gerald R. Ford.
