The broken Connecticut submarine returned to base

The US Navy's SSN22Connecticut nuclear submarine was critically damaged after colliding with an unknown object. As a result, the submarine lost a significant part of the "nose".
According to the official version, the submarine collided with an underwater rock. According to unofficial information, it was rammed by a Chinese Navy drone. The Pentagon will conduct a thorough investigation of the incident. The preliminary cost of repairs is estimated at $ 100 million.
The pictures taken in San Diego that appeared on the Internet show that the submarine does not have a bow, including torpedo tubes and sonar systems.
According to experts, such damage could be caused by an underwater drone. If the submarine had crashed into a rock, the vessel would have been completely crushed.
