Incomparable's 35-knot speed, 11-inch belt, and four-inch deck lead into a broader explanation of battlecruiser risk. A battlecruiser cannot safely exchange sustained heavy fire with a properly armoured opponent, because the better-protected ship is more likely to survive the first hit. It therefore needs rapid fire control and enough gun output to score the first and second damaging hits before the enemy lands its first. The video recasts Fisher's maxim that speed is life: ship speed matters, but so do sensors, fire control, gun numbers, and the speed with which a salvo becomes effective. The real measure is speed of engagement, not maximum speed alone.

A battlecruiser's real speed is speed of engagement
Thirty-five knots cannot protect a lightly armoured battlecruiser unless it can range, hit, and disable its opponent before heavier fire arrives.
