This is the Romanian insignia used on modern aircraft reintroduced in the early-80s.
These decals represent 700mm roundels in scale 1/72. Please consult your references to assess whether these are suitable for your model. Perfect for Romanian jets such as MiG-15, MiG-21, MiG-23, MiG-29, as well as helicopters such as Pumas and Alouettes.
These decals may also be suitable for many late-war Romanian aircraft, most notably the Ju87D Stukas, as well as some Bf109, IAR37/38/39, etc. Please consult your references.
