This is a resin and white metal ship model kit.
The USS San Francisco was built as a conventional cruiser, and among other missions, she was involved in the Battle of Guadalcanal, where she engaged with the Japanese ships Hiei and Kirishima. She also happened to be at Pearl Harbor for maintenance the day of the attack, and was able to avoid sustaining any damage. Active until the end of the war, she was sold for scrap in 1959.
This waterline-hull kit is composed of resin and white-metal parts.
