From the Yankee Modelworks website:
The Mogami class cruiser was 661 feet long, 59.1 feet wide and had a draft of 18.1 feet. She had 10 each 8”, 8 each 5” and 8 each 25mm guns along with 12 each 21” torpedo tubes. She carried three aircraft. She was built at Kaigun Kosho, Kure, Japan in 1937. The Mikuma was the second of four cruisers laid down under the terms of the London Naval Treaty. She and her three sisters were originally designed with fifteen 6.1 inch guns in triple turrets, but these were replaced in 1939 with ten 8.1 inch guns in twin turrets. The Yankee Modelworks kit of the IJN Mikuma is represented in the ship's "as-built" configuration with 6 inch gun turrets. The kit consists of resin, white metal, & photo- etch parts. A complete set of instructions is included with the kit.
