Work began in September 1944 on the 4000 e.h.p. Proteus turbo-prop originally intended to  power  the  Bristol  Brabazon  2  and Saunders-Poe Princess. The Proteus first ran in January 1947 and was later used to power the  Bristol  Britannia  at  4445  e.h.p.  A development  of  this  engine,  the  Marine Proteus, is used to power various patrol boats, hovercraft and hydrofoils.
