The P.1154 proposal is described as a supersonic aircraft with a projected speed in the Mach 1.45-1.8 range. An American Sea Control Ship requirement could have provided a reason to revisit it. In that counterfactual, British design work and American interest might combine in a joint project. The proposed revival depends on a requirement that would make the aircraft worth developing.
