Why the Lexington battlecruisers had a glass jaw

Lexington's speed, range, and firepower suited Pacific scouting, but its thin protection left it vulnerable even to Japanese Kongo-class ships and cruisers.

Question

Did the Jutland reports lead the United States to the lightly armored Lexington battlecruiser design, and what Japanese ships threatened it?

Short answer

No convincing Jutland lesson supports such thin armor; Lexington was a speed-and-range Pacific design vulnerable even to upgraded Kongos and Japanese cruisers.

Notes

The thinly armored Lexington design does not follow from a sober reading of British battlecruiser losses at Jutland. It makes more sense as a Pacific ship built around speed, range, and firepower in the same broad philosophy as American scout cruisers. Its protection created a glass-jaw problem: the ship could hit hard but could not safely absorb comparable punishment. Upgraded Kongo-class battlecruisers and Japanese cruisers would therefore remain serious threats despite Lexington's size and guns.
