What is the condition of a ship when it is considered to be "in commission"?

A ship is considered to be "in commission" when it is officially in active service. This status indicates that the vessel is ready and operational, having completed all necessary preparations for deployment or engagement in missions. Being in commission signifies that the ship has the crew, equipment, and resources required to fulfill its intended functions, whether they be military, logistical, or support operations.

When a ship is "in commission," it is flying the appropriate flag and is recognized as part of the naval fleet, often undergoing training exercises or being ready for deployment. This contrasts with other conditions such as being in dry dock, undergoing repairs, or being decommissioned, all of which signify that the ship is not currently in a state to carry out its operational duties.
