A Pearl Harbor-based Navy destroyer is home after a ten-month deployment, welcome news for the crew and their families, though questions about the mission itself are still open.

• The USS Frank E. Peterson Jr. left Hawaii in December and was at sea for more than 300 days, covering 85,000 nautical miles.
• The ship sailed with the Abraham Lincoln Carrier Strike Group, first in the South China Sea, then the Middle East during air attacks.
• It handled air defense for the strike group and was the first in the group to enter the Strait of Hormuz.
• The crew leaned on group therapy and mental health support to get through the long stretch away from home.
• Congress is now asking whether the Pentagon played down how much actual combat the strike group saw.

Outlook: The crew gets time with their families before returning to regular duties, while lawmakers press for a fuller account of what the strike group did.
