The Sukhoi 22M4 is the export version of the Sukhoi 17M4. The NATO reporting name for both is Fitter-K. Poland began using Su-22s in August 1984, when it was a member of the Cold War era Warsaw Pact. Poland joined NATO in 1997. Polish officials want to phase-out the Su-22 by 2026.

Apparently there are only a handful of countries using the Su-22, with Poland being the only NATO member flying the Fitter-K. Peru has less than a dozen Su-22s in reserve status. In 2012 Peru signed a ‘codification’ agreement with NATO but is not considered a member, or partner, of NATO.
