Throughout the 1920s and 1930s, some officials within Poland remained interested in the establishment of a national bomber force, in some cases for prestige value rather than in terms of strict military value. During 1927, the Department of Aeronautics authorised the development of the Lublin R-VIII, a large single-engined reconnaissance bomber. In the following year, the department ordered Polish aviation manufacturer Państwowe Zakłady Lotnicze (PZL) to make preparations towards the development of a heavy multi-engined night bomber; while numerous proposals and design studies were made by both PZL and private factories, but none were approved for further development by the department. Instead, it was decided to procure a number of Dutch-built Fokker F.VII to meet the bomber role, the first of which being delivered during 1929, despite condemnation of the aircraft's poor defensive armament, limited payload capacity, and excessive weight.
