Design and development
Development of the L-159 began in 1992 using Rockwell Collins (eventually Boeing) as the avionics integrator. The Czech Air Force ordered 72 of the aircraft in April 1995.[1]
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.[1]
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.
Operational history
The Czech Air Force is the primary operator, receiving the latest avionics upgrades.
Variants
L-159A
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),[3] 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.
L-159B
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.
L-159T1
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.
L-159T2
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.
Operators
Current operators
- Czech Air Force – in service 15 L-159As and 6 L-159T1s (remaining are in cold storage in Aero Vodochody)[4]
- Iraqi Air Force - 15 L-159 aircraft purchased (10+3 L-159As and 2 L-159T1s).[5] The first two Czech L-159s were delivered to Iraq on 5 November 2015.[6][7]
Civilian operators
- Lewis Fighter Fleet LLC - 3 L-159As[8] These aircraft were bought from EADS-CASA in July 2013. In 2009 EADS-CASA of Spain exchanged with the CzAF four CASA C-295 for three L-159As, two L-159T1s and 130 million Euros.[9] Later the two L-159T1s were returned by EADS-CASA to the Czech Republic as compensation for the C-295M not meeting the counter measures requirements of the CzAF at the time of delivery.[10] This problem has been solved by EADS-CASA three years later and the remaining three L-159As resold by EADS-CASA to Lewis Fighter Fleet LLC.
- Draken International Inc. - 21 L-159Es: a civilian U.S. company that cooperates with the U.S. Army, will buy 21 planes in total.[11][12][13][14]
Accidents and incidents
On 24 February 2003 L-159A (No. 6056) crashed during weapons trials of the podded 20mm cannon "Plamen", pilot killed.[15]
On 22 November 2012 an L-159A from the Czech Air Force (No. 6061) crashed during training flight in central Bohemia. Pilot (First Lieutenant Ondřej Sovina) was killed.[16][17]
