Lexington Class Battle Cruisers: Key Ship Series 2, Ship 4

The planned Lexington-class names show that the US Navy expected the battlecruisers to carry unusual political and national weight.

The official renaming of the historic USS Constitution shows how seriously the Navy prepared to transfer the name to CC-1.

A fast, imposing Lexington could have projected US naval power through world cruises and diplomatic visits before combat.

The class was meant to secure American scouting and contest Japanese battlecruisers such as the Kongōs and planned Amagis.

A spectrum from presence and scouting work to sustained capital-ship combat explains why later battlecruisers needed more protection.

Lexington suited presence, commerce, and scouting work, while direct capital-ship combat exposed the cost of her limited protection.

The comparison sets Lexington's speed, range, 16-inch battery, and turbo-electric machinery against Hood's heavier protection.

Six hulls divided among four American yards show the industrial reach of the programme.

Some apparent portholes in a later Lexington rendering may have been deleted or painted rather than openings through the armour belt.

The design makes more sense as a Pacific fleet asset expected to avoid unsupported duels with stronger enemy battlecruisers.

Treaty limits would have made surviving Lexingtons scarce, fast capital ships and strong candidates for repeated modernization.

Without an arms-control halt, completed Lexington, G3, N3, Colorado, South Dakota, Nagato, Amagi, and Francesco Caracciolo programmes would have forced another round of capital-ship design.

The cancelled programmes show which capabilities and industrial commitments governments accepted losing through naval arms control.
