The Aero L-159 ALCA (Advanced Light Combat Aircraft) is a Czech-built multi-role combat aircraft. It is in service with the Czech Air Force. It is derived from the Aero L-59 Super Albatros.

Design and development[edit]

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[edit]

The Czech Air Force is the primary operator, receiving the latest avionics upgrades.

Variants[edit]

L-159A[edit]

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),[2] 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[edit]

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[edit]

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[edit]

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[edit]
