Lion-class battleships in Cold War service

If the Lion-class battleships had been completed, how long might they have served and what Cold War modernization would they receive?

The answer suggests a Vanguard-and-Lions rotation into the 1960s, reserve status in the 1970s, and a possible Falklands-era return if one hull remained usable.

The panel treats the Lion class as a force-structure problem rather than a simple nostalgia ship. A three-ship capital-ship pool with Vanguard could support rotation, but by the 1970s the hulls would face manpower, maintenance, and role questions. The most concrete payoff is the Falklands scenario, where a usable Lion in reserve might have offered a major bombardment and command asset, though probably not a long postwar future.
