A state-of-the-art construction, one of the first all-metal monoplane fighters in the world, in 1933–1935 it was a main fighter of the Polish Air Force. It was replaced in Polish service by its follow-up design, the PZL P.11c. More than 30 P.7 fighters remained in service in the Polish Defensive War of 1939, scoring several kills despite their obsolescence." ] ,
