The national flag of the Solomon Islands was adopted officially on November 18, 1977. The five main island groups are represented by the five stars. The blue is supposed to represent the surrounding ocean, while the green represents the land. The yellow stripe is symbolic of the sunshine.
The civil ensign (for merchant ships) and state ensign (for non-military government vessels) are red and blue flags, respectively, with the national flag in the canton. The naval ensign (for police vessels) is based on the British white ensign, a red cross on a white field, also with the national flag in the canton.
