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)
- Iraqi Air Force - 10 (13) L-159As and 2 L-159T1s (8 L-159As from Aero Vodochody storage plus 3 for spare parts, 2 L-159As and 2 L-159T1s from Czech Air Force) ordered, with deliveries to be September 2014.
- Lewis Fighter Fleet LLC - 3 L-159As (These aircraft were bought from EADS-CASA in July 2013. In 2009 EADS-CASA of Spain exchanged with the CzAF one CASA C-295 for three L-159As and two L-159T1s. Later L-159T1s were returned to the Czech Republic as compensation for the problem with the counter measure not meeting the CzAF requirements.)
- Draken International Inc. - 28 L-159: a civilian U.S. company that cooperates with the U.S. Army, will buy 28 L-159 planes (24 intact and 4 broken down for spares) in a deal worth up to $25.8 million.
