U.S. Navy Commander Greg Hicks says there were no injuries reported from the accident late Sunday and officials were investigating the cause.
A U.S. Coast Guard spokesperson said the collision happened around 11:30 p.m. about 50-miles northwest of Point Loma. Three people were on board the civilian boat. None of them were hurt.
The civilian craft was deemed seaworthy and the Coast Guard escorted it back to Oceanside. The collision is still under investigation.
Hicks says the USS Shoup, a guided-missile destroyer, suffered scrapes but both vessels were functioning. The 509-foot-long Shoup carries about 380 people and is training out at sea with the Abraham Lincoln strike group.
Hicks said the civilian vessel is believed to be a 21-foot-long dive vessel.
