The first 12 MiG-29 (nine MiG-29As, three MiG-29UB) were delivered to Poland in 1989–1990. The aircraft were based at Mińsk Mazowiecki and used by the 1st Fighter Aviation Regiment, which was reorganized in 2001 as "1 Eskadra Lotnictwa Taktycznego" ("1. elt"), or 1st Tactical Squadron (TS). In 1995–1996, 10 used examples were acquired from the Czech Republic (nine MiG-29As, one MiG-29UB). After the retirement of its MiG-23s in 1999, and MiG-21s in 2004, Poland was left for a time with only these 22 MiG-29s in the interceptor role.
