Montana and Conqueror replacing Anglo-American battleships in World War I

What if all British and American World War I battleships were replaced by Conqueror- and Montana-class ships?

The technological and numerical advantage would be so large that existing enemy fleets and coastal defences could not contest them.

Replacing British battleships with the hypothetical Conqueror and American battleships with Montana would make the imagined Jutland overwhelmingly one-sided. The discussion emphasizes radar-directed 16- and 16.5-inch guns and the initial condition that battlecruisers remain unchanged, allowing Jellicoe's battle line to outrun Beatty's force. A later amendment replaces British battlecruisers with Admiral-class ships; Conqueror's speed is corrected during the exchange to 29.5 knots. The proposal includes pre-dreadnoughts as well as the Grand Fleet, producing an approximate estimate of 90 British replacements. Coastal operations would also change, with radar-directed bombardment and spotting aircraft threatening the Dardanelles forts. At Coronel, replacing the British pre-dreadnought with the much stronger ship is expected to reverse the encounter with von Spee. These are consequences of the hypothetical replacement conditions, not descriptions of historical ships or battles.
