 S.6/43 was allowed to proceed, and there are indications that Shorts submitted two uninvited tenders, a single-engined Bristol Centaurus design and a twin-Rolls-Royce Merlin design.However, none of the original S.6/43 submissions was adopted and no reference to the Shorts submissions has been located in the official documentation.Focus instead shifted to splitting the requirements, with the torpedo bomber requirement becoming O.5/43, eventually leading to the Fairey Spearfish, while S.11/43 was written for a reconnaissance aircraft able to operate as a bomber.
