The Lasta 95 is a light military trainer aircraft produced by Utva Aviation Industry. It is a tandem two-seater low-wing trainer with a metal airframe. The aircraft is capable of basic training functions including aerobatics, instrument and tactical flying, as well as basic training in use of weapons. The first prototype of Lasta 1 flew on 2 September 1985, while the first prototype of the current version, Lasta 3 flew on February 26, 2009. Lasta in Serbian is the swallow.

Design and development

Lasta 95 (Swallow 95) in 2011.

The Lasta was originally developed to be a replacement of the Utva 75 and, partially, Soko G-2 Galeb, which had been the most commonly used trainer aircraft of the Yugoslav Air Force up until 1991. The first prototype Lasta 1 was completed by the spring of 1985. Following completion of the initial testing phase, the first flight was achieved on September 2, 1985. In January 1989, design of a modified version – Lasta 2 was started, following changes in Yugoslav Air Force requirements. Lasta 2 was lighter, with shorter fuselage and a new electronics system including fire control Ferranti ISIS D-282. By the early 1990s Utva, and her partners, have produced enough parts for the completion of 10 pre-production airframes. During the 1999 NATO bombing of Yugoslavia, all five existing prototypes were destroyed during the bombing of Utva Aviation Industry (a sixth prototype survived with damage and was donated to the Aviation Museum at Belgrade Nikola Tesla Airport).

In 2006 development of the Lasta was restarted. The new version was known as the Lasta 95 and followed basic concepts of Lasta 2, with updates due to newer available technology. In 2009 it was announced that Iraq will purchase 20 of these trainer aircraft.

With its specifications and updated avionics, the aircraft will ensure full pilot training for all elements of airplane application including:

  • basic flying,
  • figure flying,
  • navigation flying,
  • basic elements of night flying,
  • category II instrumental flight,
  • basic elements of gunning, rocketing and bombing (GRB)
  • Light close air support of counterinsurgency operations and area patrol / light attack missions

Future improvements and developments

It is possible to install ejection seats, but with higher cost and weight of the airplane. It is also possible that new containers with armaments and sensors would be developed for Lasta 95, as well as a proposed turboprop version of the aircraft with more advanced training and combat capabilities.

Versions

There are three-factory versions of Lasta 95.

Lasta 95N

This light piston-propeller training aircraft is primarily intended for initial and basic training of military pilots. With in-line tandem seating, the trainer was developed in accordance with the Federal Aviation Regulations (Joint Aviation Requirements) 23 regulations for acrobatic category of airplanes and it provides an easy transition to Kobac and then to jet at higher training levels. The LASTA is equipped with a six-cylinder 224 kW (300 HP) engine of the opposed-cylinder type, and a two-bladed metal propeller Hartzell HC-C2YR-4CF/FC 8475-6, which provides maximum flight velocity (at an altitude of 3000m and a take off weight of 1085 kg) of 345 km/h. The empty weight is 888 kg, and the maximum take off weight is 1210 kg for the aerobatic category and 1450 kg for the utility (armed) category. The total aircraft length is 7.97m. The trapezoidal wings have a wingspan of 9.7 m and a surface of 12.9 m2. The altitude barrier of flight is 6000 m. This propeller-driven low-wing aircraft has a tricycle retractable landing gear suitable for rough-field operations. Onboard GPS and Instrument Landing System (ILS) support the operations during CAT-II weather conditions. The aircraft is equipped with Mode S transponder for flight identification.Besides for training purposes, it can be used for combat fire training, rocket firing and bombing. The armed version of the LASTA 95 can be equipped with 7.62 mm or 12.7 mm machine guns, 57 mm rocket launchers or bombs weighing up to 120 kg on two hardpoints.

Lasta 95V-54

Lasta 95V-54 designation is for Serbian Air Force and Air Defence. Differences between Lasta 95N and Lats 95V-54 are in following:

  • Engine Lycoming AEIO-580-B1A, with 315 hp (332 kW, under H = 0 and 2700 rpm)
  • Two-blade metal propeller HARTZELL HC-C2YR-4CF/FC 8475-8
  • New propeller cap
  • Modified primary flight controls
  • Modified engine controls with less friction
  • New instruments for measuring temperatures and oil pressure and temperatures of cylinder block and exhaust gases in both cabins
  • New radio stations Bendix/King for UHF with antennas
  • New gun sight AKN-09 Teleoptik Zemun which supports containers with Machine gun, bombs and unguided rocket launcher
  • Two under-wing hard points for weapons max allowed 120 kg
  • New glass cockpit with Garmin G500 avionics suites, which includes a primary flight display (PFD) and a multi-function display (MFD). The aircraft also integrates an instrumental flying simulation system.
  • Introduction of new composites materials in some parts of the plane

Lasta 95P-2

It is a same version as the Lasta 95V-54 designated for export customers with possibility of slight differences at customer request.

Variants

  • Basic version of the aircraft is built against the requirements for aerobatic category loads of +6.0 -3.
  • Armed version of the aircraft is built against the requirements for utility category with loads of +4.4 -1.8.

Operational history

In December 2007, the Iraqi Air Force ordered 36 (20 firm with an option for 16 units) Lasta 95 aircraft.[2] The first Lasta 95s were transferred to Iraq on August 5, 2010.[3] Last of the 20 ordered Lasta 95 aircraft arrived in February 2012.[4] According to media reports, the aircraft have been used during the Iraqi war against ISIS.[5]

By March 2012, two of 15 ordered Lasta 95 aircraft began service with the Serbian Air Force.[6]
