L-39NG is a project concerning a new, highly efficient trainer that will be able to serve in the training syllabus as a basic, advanced and LIFT trainer thanks to advanced avionics. The L-39NG is based on the aerodynamic concept of the current L-39, but is manufactured using new technologies and contains modern systems.

In 2018, there were several major milestones in the project of the new L-39NG aircraft. At the beginning of the year, Aero launched the assembly line for the first four aircraft; the final assembly of the first L-39NG began in the summer 2018. On Friday, October 12, the new aircraft thus could be introduced to the public for the first time during a roll-out ceremony. Even before the end of the year, December 22, 2018 factory test pilots David Jahoda and Vladimír Továrek took off with the L-39NG for the first time. Starting June 2019, this aircraft will be used for flight-testing and other development tests. The second aircraft is designed for static tests, the third for fatigue tests. The fourth aircraft produced will be involved in flight tests. L-39NG certification is planned for the end of 2019.

In addition, in 2018, Aero managed to conclude agreements with three potential customers for the new aircraft. First, in April, it signed an agreement with Senegal Air Forces interested in four aircraft in a light combat configuration. In July, Aero presented two other serious potential customers for the L-39NG. Aero further continued in the intensive promotion of the new aircraft and in negotiations with potential customers on almost every continent.

Technology Demonstrator of L-39NG is used as a testbed for our own program L-39NG. We can implement and properly test all the technologies that we want to use in our new aircraft later. It is "One of a kind" and Aero bought this L-39 from Ukraine specifically for this mission. The aircraft is built on the legendary airframe of L-39, but we fitted the aircraft with state of the art system avionics, new engine FJ44-4M by Williams International, several changes in cockpit and the external fuel tanks have been substituted by the wet wing technology, which keeps the fuel inside the whole wing.
