USS Connecticut Damage Photos The damaged submarine has made her way home and the collision seems impressive. See below for a number of pictures:

The United States Navy Seawolf class nuclear fast-attack submarine, the USS Connecticut (SSN-22), slammed into a “submerged object” on Oct. 2, 2021.
The US Pacific fleet issued the following statement:
The Seawolf-class fast-attack submarine USS Connecticut (SSN 22) struck an object while submerged on the afternoon of Oct. 2, while operating in international waters in the Indo-Pacific region. The safety of the crew remains the Navy’s top priority. There are no life-threatening injuries.
The submarine remains in a safe and stable condition. USS Connecticut’s nuclear propulsion plant and spaces were not affected and remain fully operational, the extent of damage to the remainder of the submarine is being assessed. The U.S. Navy has not requested assistance. The incident will be investigated.
A Potential Explanation For the USS Connecticut
Seamounts do pop up surprisingly quickly; they are volcanic/seismic phenomena, after all, and it’s amazing how quickly a volcano can grow, with surprisingly little fuss. A 5,000 footer could easily appear between hydrographic surveys with minimal signs on the surface, and just a distant rumbling on the hydrophone arrays.
Of course there are those who will say the US and Chinese had a submarine collision. However, there is no evidence to back up that assertion.
