The United States Navy SSN-21 Seawolf attack nuclear submarine arrived at the port of Yokosuka in Japan on October 4, after the United States Navy used the SSN-22 Connecticut attack nuclear submarine to operate in the South China Sea, during which it directly collided with the submarine mountain and has not yet been repaired. The ASSN-22 Connecticut belongs to the Seawolf-class, and now the United States Navy has once again used the Seawolf-class nuclear submarine to operate in the Asia-Pacific region, and there is already a rhythm of "forget the pain after the scar".
The United States Navy regularly deploys nuclear submarines in the Asia-Pacific region, in addition to attack nuclear submarines, there are also strategic missile nuclear submarines, and there will also be activities near the first island chain of cruise missile nuclear submarines.
Recently, the deployment of the US military in the Asia-Pacific region has been intensified, because in addition to the naval force, the air force is also a frequent activity, including the deployment of F-22A fighter jets to multiple bases in the first island chain.
