If Tiger exploded during the First World War

What if Tiger exploded during the First World War in a way comparable to Mutsu?

Accelerated Admiral-class construction is suggested, with several completions putting pressure on the postwar treaty settlement.

The scenario uses roughly 1916 as the equivalent date. At least two Admiral-class ships would probably be pushed through quickly in the existing design. Completing three or four raises larger treaty questions. Several ships over 40,000 tons would be harder to accommodate than one exceptional vessel. Possible American demands for more Colorados and Lexingtons would accompany British interest in 16-inch-gunned ships. These are conditional negotiating possibilities.
