Assume the German facilities for HTP are destroyed and thus no cheap quick means to establish bulk production of HTP.
This increases emphasis on new nuclear propulsion for ships and submarines. As resources are not diverted to HTP development.
Having a higher priority from 1953 as argument for nuclear submarines wins out.
Analysis of earlier opens prospect of submarines capable of carrying ballistic missiles.
1955 accelerated program as sufficient quantities of uranium becomes available. Approved shoreside prototype that year.
1957 Defence Review increases and secures long-term plan and funding.
Meanwhile.....
Only the LOx/Kerosene motor effort proceeds as HTP production is very low.
While OR.301 is issued in '51, the potential exists for abandonment in 1952 as E.T.Jones thought a Mach 2 aircraft with twin jet engines was more important.
Potentially Saro are awarded ER.134T submission P.163.
Alternatively the 1953 defence cuts and the focus on mixed power interceptors that led to F.177.
