The Aero L-39NG is a Czech two-seat subsonic jet trainer and light-attack aircraft developed by Aero Vodochody as the modernized successor to the L-39 Albatros family. Aero now markets the type as L-39 Skyfox, and the program pairs a Williams FJ44-4M turbofan with modern avionics, a 15,000-flight-hour service life, and training, reconnaissance, and light-combat roles.
Held in the Various Conflicts archive because the open-source record confirms the L-39NG program and current operators, but not a precise named modern conflict assignment.
