Design and development
The maiden flight of the L-159 occurred on 4 August 1997 with a two-seat version. On 18 August 1998 the single-seat version first flew; it was completed to Czech customer specifications. April 2000 marked the first delivery of an L-159 to the Czech Air Force.
In 2009, Aero Vodochody selected V-Dot Systems (split off from Boeing) as the L-159 avionics integrator. V-Dot will replace the Honeywell multi-function displays (MFD) and upgrade the mission processors to support new functions.
The Czech Air Force is the primary operator, receiving the latest avionics upgrades.
The L-159A is a single-seat light multi-role combat aircraft designed for a variety of air-to-air, air-to-ground and reconnaissance missions. The aircraft is equipped with a multi-mode Doppler Grifo-L radar (a variant of the Grifo-F x-band multi-mode, pulse-doppler radar), for all-weather, day and night operations. It can carry a wide range of NATO standard stores including air-to-air and air-to-ground missiles and laser guided bombs. The L-159A is in operational service with the Czech Air Force and in production. Avionic upgrades are designed and developed by V-Dot Systems Inc.
There are two different configurations being used by the CzAF:
1. Using the Honeywell MFDs.
2. Using the Vdot MFDs.
The L-159B is a two-seat derivative of the L159A primarily designed for Advanced and Operational/Lead-In Fighter Training. The L-159B configuration can also be tailored to customer specific requirements and adapted to needs of basic training as well as combat missions including air-to-Ground, patrol and reconnaissance missions.
Note: only one prototype made by Aero Vodochody.
The L-159T1 is a two-seat trainer derivative used by the Czech air Force. All L-159T1s are modified L-159A airframes taken from storage. First flight 8 March 2007.
The L-159T2 is a two-seat trainer derivative based on the designs of the L-159T1 and L-159A. Instead of mirroring the instruments to the rear seat like the L-159T1, the new two-seater will have independent instruments. The avionic systems will be interchangeable with the L-159A and use the same software configurations. Aero Vodochody will be using parts from the L-159B to build the L-159T2 prototype. Avionic upgrades are designed and developed by V-Dot Systems Inc.
- Czech Air Force – in service 19 L-159As and 6 L-159T1s (remaining are in cold storage in Aero Vodochody)
- In 2009 three L-159As and two L-159T1s were exchanged with EADS-CASA of Spain for a fourth CASA C-295 for the CzAF. In July 2012 one L-159T1 was returned to the Czech Republic as compensation for the problem with the counter measure not meeting the CzAF requirements. In July 2013 EADS sold three single-seat L-159As to a private USA company located in Florida (not approved for flight since these aircraft were taken from storage and never overhauled). Second L-159T1 was returned to CzAF in September 2013 (also as compensation for C-295 counter measure problem).
On February 24, 2003 L-159A (No. 6056) crashed during weapons trials of the podded 20mm cannon "Plamen". Pilot (Captain Petr Vašíček) was killed.
On November 22, 2012 another L-159A (No. 6061) crashed during traning flight at central Bohemia. Pilot (First Lieutenant Ondřej Sovina) killed.
