Factual error: Atop the desk in the Captain's stateroom is a model of a 5"/25 wet mount gun. The 5"/25 was designed for, and mounted on, U.S submarines; however, it was not introduced into service until 1944, and this is set at the start of World War 2.
Factual error: When Chief Tostin and Major Heywood are arguing in the engine room, Tostin says "I'm a machinist's mate, not a laundry feeler!" Actually, his rating would have been motor machinist's mate (later changed to engineman); machinist's mates work with steam propulsion plants, not diesel engines.
Factual error: Lt. Holden and his men raid a warehouse on the night of 10 December 1941. When Holden is confronted by an MP, he explains his blackened face by saying it was a directive from Admiral Nimitz. However, at the time, Admiral Kimmel was in command of the Pacific Fleet. Nimitz was Chief of the Bureau of Navigation in Washington, and did not replace Kimmel until 17 December.
Suggested correction: Holden and men didn't raid the warehouse on December 10. The attack on the Sea Tiger occurred on December 10, and Holden wasn't part of the crew yet. He joined the crew after repairs were being made to the sub, so it is possible that by the time he received the transfer orders and got to where Sherman was stationed, Admiral Nimitz had already taken over.
