A 15-inch Tiger turns speed into a tactical problem for other navies, especially the United States. A three-knot advantage is judged sufficient to influence engagement timing or range, but too small to withdraw decisively and return from another angle at will. A seven-knot advantage would permit that wider freedom to disengage, reposition, and reengage. American planners would then have reason to reconsider the speed of their battle line.

How seven knots changes tactical control
A seven-knot advantage could let a ship control engagement timing and range, giving American planners reason to reconsider a slower battle line.
