The Aero L-159 ALCA is a Jet Trainer with Sharp Teeth

Developed by Aero Vodochody in the Czech Republic, the L-159 ALCA (Advanced Light Combat Aircraft) is a lightweight attack platform based on the L-39 Albatross jet trainer. This aircraft not only serves as a platform for advanced pilot training but also excels in ground attack, reconnaissance, and close air support missions.


Development and Design

The early 1990s saw the Czech Air Force grappling with the challenge of replacing its ageing L-39 Albatros trainers. This period of transition necessitated an aircraft that was not only advanced and versatile but also cost-effective to meet the stringent demands of modern warfare.

Enter Aero Vodochody, a firm with a rich legacy in aircraft manufacturing, who took upon this challenge and embarked on the development of the L-159.
