Pols can be, ah, selective in their memories. Macmillan, Memoirs/VI,P335: (vice Douglas MGR-1B Honest John for France (yes, really!), Italy, FRG and UK, US urged Sperry MGM-29A Sergeant SSM to) “the tune of umpteen Mn.$”; UK declined “not a European rocket. It’s a racket of US industry.” BAC Blue Water was: “a better weapon (but pressure for Sergeant) was irresistible (on) favourable terms more common (for) washing machines (8/62 forcing) us to cancel at considerable loss” (£32.1Mn.)
In fact, once UK decided to restrict SSM deployment to BAOR, then inter-operation and free US warheads orphaned any UK-solo product. We perpetuated our HJs to 1977, then took Lance on the customary washing-machine deal.
