R20C

R20C is a designation that can refer to several different things, most commonly an aircraft or a vehicle. One prominent example is the Lockheed R2V, a twin-engine seaplane developed for the United States Navy during World War II. While it was based on the Lockheed XR4C, the R2V featured a modified fuselage and wing. The R2V was intended for reconnaissance and bombing missions and underwent testing, but ultimately did not enter widespread service.

Another significant use of R20C is associated with the Rolls-Royce R20C engine. This was a variant of the Rolls-Royce Merlin aero engine, a powerful V12 piston engine that powered many Allied aircraft during World War II, including the Supermarine Spitfire and the North American P-51 Mustang. The R20C designation would have indicated specific performance characteristics or configurations of the Merlin engine.

In other contexts, R20C might appear as a model number or identifier for various industrial components, electronic devices, or even specific chemical compounds. Without further context, it is difficult to pinpoint a single definitive meaning for R20C. Its specific application depends heavily on the field or industry in which it is encountered.
