Shimakaze's quoted specifications are about 2,600 tons standard displacement and nearly 3,400 tons fully loaded, with a speed close to 41 knots. The stated range is 6,000 nautical miles at 18 knots. A rule of thumb divides fuel endurance equally between the outward journey, the return journey and combat manoeuvring. Applying that rule to the stated range gives a rough outward radius of 2,000 nautical miles, with the remaining endurance reserved for the return and combat. The published range therefore cannot all be treated as distance available for an outward operation.

Shimakaze's speed, range and combat fuel reserve
Separate a quoted 6,000-nautical-mile range from the fuel needed to go out, return and manoeuvre in combat.
