Aircraft carrier (or simply carrier) is a 6-cell still life, and the smallest still life that has more than one island. It consists of two pre-blocks.

Commonness

Aircraft carrier is the fifteenth most common still life in Achim Flammenkamp's census, being less common than long barge but more common than paperclip.[1]

Aircraft carrier is the fifteenth most common still life on Adam P. Goucher's Catagolue, being less common than long barge but more common than paperclip. Among all still lifes with 6 cells, it is the fourth most common, being less common than barge but more common than snake.[2] It is also the twentieth most common object overall on Catagolue.

Glider synthesis

There are three 3-glider collisions that produce an aircraft carrier as well as another object. The first one leaves a stray block, the second a beehive and the third a blinker, leading to three two-stage 4-glider syntheses for the still life. Other 4-glider collisions that make a clean aircraft carrier are also known.
