S-Class Torpedo Solution From A Novel I Am Reading

[james_nix]

Here is another weird part:

Reynolds punched the firing button. “Firing one.”
Frankie shuddered as the torpedo ejected from its tube, a ton of metal and explosives suddenly exiting the boat.
Reynolds counted eight seconds on his stopwatch and pressed the plunger for the second tube. “Firing two!”
Another eight seconds: “Firing three!”
Then: “Firing four! Secure all tubes.”
Four torpedoes in a longitudinal spread. If all went according to plan, the first torpedo would hit the cruiser close to the bow. The ship’s momentum would carry it forward, allowing the other fish to nail her both amidships and near the stern. As the cruiser was nearly six football fields in length, the odds looked good.
The torpedoes streamed in a single line toward the cruiser. At this range, nearly two minutes would pass before the contact-exploders struck the hull and detonated.

Eight seconds between shots!! That is quite the spread, then again, the cruiser was six football fields in length, but it was a Furutaka-class cruiser which is only about 600 feet in length, about 2 football fields. Maybe time to put the book down.
