Which flag is flown from the jackstaff at the bow of a commissioned ship?

The flag that is flown from the jackstaff at the bow of a commissioned ship is the Union Jack. This flag is an important symbol of the nation's sovereignty and is displayed on naval vessels up until the moment they are underway. It represents the United Kingdom and is typically flown when the ship is at anchor or moored to denote its status.

The Union Jack serves an important ceremonial purpose in naval traditions. It indicates that the ship is in port and embodies a sense of national pride and honor. When at sea, the national ensign is raised at the stern of the ship, while the Union Jack remains at the bow. Recognizing these distinctions enhances understanding of naval customs and practices, which is crucial for those serving in the Navy.
