27. Salutes to National Flags
(1)Salute to the national flag of a country consists of 21 guns.(2)The Captain of a ship, or the senior officer of more than one ship, visiting a foreign port where there is a fort or saluting battery, or where a ship of the nation may be lying shall salute the national flag with 21 guns, on being satisfied that the salute will be returned. A salute shall not be fired when the ship is passing through territorial waters with no intention of anchoring, or making fast in any way, in them, even if a saluting station is passed, unless unusual circumstances make it desirable. The salute shall be fired on each occasion that a ship visits a foreign port, except that of a ship leaving port temporarily, when, by agreement with the local authorities, the salute on her return may be dispensed with.(3)When a ship visits a foreign port where there is no saluting battery and no ship of the nation is lying on arrival, and a ship of the nation arrives during the visit, a salute to the national flag shall only be fired after mutual agreement between the Senior Officers of the ships concerned.(4)If the ship of a senior Indian officer is already present in the port, the junior will not fire a salute.(5)Salutes to a national flag shall not be fired by Indian Naval Ships when visiting Commonwealth Countries.
