The '''Aero L-39NG''' ('''N'''ext '''G'''eneration) is a [[turbofan]]-powered military [[trainer aircraft]] currently under development by [[Aero Vodochody]]. It is a successor of the [[Cold War]] era [[Aero L-39 Albatros]]. The aircraft is being developed in two versions (stages). While the L-39NG Stage 1 is an upgrade of the original L-39 airframe with a new engine and avionics, the Stage 2 is a newly-built aircraft with several design improvements such as the [[wet wing]] without the type's distinctive [[Wing tip|wingtip]] fuel tanks.<ref name="Osborne" /> Serial production should begin in 2019.<ref>{{cite news|title=Aero L-39 Albatros Advanced Trainer / Light Attack Aircraft - Czechoslovakia|url=https://www.militaryfactory.com/aircraft/detail.asp?aircraft_id=436|publisher=MilitaryFactory|date=3 January 2018}}</ref>
