A fleet of Malta carriers and Lion battleships would transform British strategy

How would the war change if British battleships became Lion-class ships and carriers became Malta-class ships in 1941?

Britain would field a much stronger fast battle line and carrier force, changing calculations for Japan, Germany, Italy, Force Z, and operations across the war.

The outcome depends partly on whether the transformed carriers receive air groups, although Britain could fill gaps with rapidly converted Sea Hurricanes and American aircraft. Converting every battleship would produce roughly fourteen Lion-class ships, each capable of 28 knots and carrying nine 16-inch guns. Force Z could include Lion-class battleships and a Malta-class carrier, radically changing its vulnerability and the composition of the Eastern Fleet. Germany and Italy would lose many favourable capital-ship matchups, while the enlarged carrier fleet would transform operations and fleet allocation across several theatres.
