How fewer Pearl Harbor losses could keep US battleships active

Would US battleship strategy continue if only two battleships were sunk at Pearl Harbor?

Probably, because the surviving battle line would remain usable, although inadequate tanker support would still restrict where it could operate.

The counterfactual leaves most American battleships intact after Pearl Harbor and asks whether the pre-war battle-line strategy survives. The United States Navy would probably try to use the force because a much smaller proportion of its capital ships would be damaged. Hull numbers would not be the only limit: too few fast tankers could still prevent sustained operations across Pacific distances. The extra battleships would likely matter more around Guadalcanal than in an immediate relief of the Philippines, unless commanders accepted an exceptionally reckless advance.
