US nuclear submarine collides with US warship off East Coast

The USS Montpelier nuclear-powered submarine has collided with the USS San Jacinto aegis missile cruiser, while being led during exercises off the East Coast by the aircraft carrier USS Harry S. Truman.

The Saturday incident caused the cruiser’s sonar dome to collapse besides leading to possible other damage, but did not cause any casualties, Reuters reported. The dome covers some of the warship’s electronic navigation, detection, and ranging equipment.

Prior to the incident, the cruiser spotted the submarine’s periscope, but failed to avoid the collision.

A related investigation is underway and overall damage to both vessels is still being evaluated.
