The image shows a close-up of a large gun mounted on the side of a ship. The gun is grey in color and appears to be made of metal. It is mounted on a metal frame with a rope attached to it. The rope is coiled around the gun and is secured to the ship's deck. The ship is docked at a dock with other ships visible in the background. There is a large white object on the left side of the image, possibly a radar or other equipment. The sky is overcast and the overall mood of the photo is gloomy.
