[Ukro Turk]

Designation:ASCOD 105 LRF
Manufacturer:General Dynamics European Land Systems-Steyr GmbHProduct type:Armoured VehiclesName:Light tank

Development

The ASCOD 105 light tank has been developed as a private venture for the export market by ASCOD AIE which is jointly owned by Santa Barbara ol Spain and Steyr-Daimler-Puch of Austria.

The ASCOD 105 light tank consists of a modified ASCOD armoured infantry fighting vehicle chassis which is already in production for the Spanish Army. It is fitted with the complete South African LIW turret installed on the private venture South African Reumech OMC Rooikat 105 mm armoured car (8 x 8) (covered in detail in the Reconnaissance vehicles section).

The first prototype of the ASCOD 105 light tank was completed late in 1996 and it has been demonstrated in Austria to a number of potential export customers, including some in Asia.

Description

The hull of the ASCOD 105 light tank is all-welded steel armour which provides protection from small arms fire and shell splinters.

The driver is seated front left with the power pack to the right and above his position is a single-piece hatch cover that lifts and opens to the rear, in front of this are three periscopes, the centre one of which can be replaced by a passive periscope for driving at night.

The all-welded steel turret is in the centre with the commander and gunner on the right and the loader on the left. The commander has a single-piece hatch cover that opens to the rear and eight periscopes for all-round observation and a roof-mounted stabilised day sight. He also has a monitor of the gunner's main thermal sight.

The gunner has a stabilised day/thermal sight incorporating a laser range-finder and an observation periscope. The loader has a single-piece hatch cover that opens to the rear plus two periscopes and a vision block. An ammunition resupply hatch is provided in the left side of the turret.

Main armament is a fully stabilised 105 mm LIW GT 7 gun that fires standard natures of 105 mm ammunition with a 7.62 mm machine gun mounted coaxial with the main armament and a roof-mounted 7.62 mm antiaircraft machine gun.

Suspension is of the torsion bar type with rotary dampers for the first and last roadwheel stations. The suspension either side consists of seven dual rubber-tyred roadwheels with the drive sprocket at the front, idler at the rear and track-return rollers.

The rear hull door of the ASCOD armoured infantry fighting vehicle is retained and for a detailed description of the chassis and turret - the reader is referred to the detailed entries previously mentioned.

If required, additional armour can be fitted to provide a higher level of battlefield survivability.

Low Profile Turret on ASCOD

First firing trials of the General Dynamics Land Systems 105 mm Low Profile Turret (LPT) installed on an ASCOD infantry fighting vehicle (IFV) chassis were successfully carried out in the US late in 1998.

The LPT was originally developed in the early 1980s and first installed on a tracked chassis called the Armored Gun System and then the Direct Fire Support Vehicle.

The latest generation LPT has a number of significant improvements and features a new turret structure that is lighter and stiffer. The 105 mm M68A1 rifled tank gun is fed by an automatic loader mounted below the turret ring and between the commander (seated on the right) and the gunner (seated on the left).

The 105 mm M68A1 gun has been fitted with a cam operated drop-block breech assembly, bore evacuator, muzzle reference mounting collar and an integral muzzle brake. Low recoil is made possible by the installation of a four cylinder recoil assembly.

. By mounting the 105 mm M68A1 gun externally the LPT is not only much lighter than a conventional turret, allowing it to be installed on much lighter tracked and wheeled armour vehicles, but is also much smaller and therefore much more difficult to hit.

The 7.62 mm machine gun is mounted coaxial with the 105 mm M68A1 gun and a 7.62 mm or 12.7 mm machine gun or a 40 mm grenade launcher can be mounted at the commander's station.

The commander and gunner have vision periscopes while the gunner's primary sight has a dual axis stabilised head mirror, second generation FLIR, eye safe laser range-finder and ' eight direct viewing options.

The commander has a panoramic sight which allows the vehicle to undertake hunter/killer target engagements. Turret traverse and weapon control is all electric and stabilised and either commander or gunner can aim and fire the armament.

It was expected that the LPT would first be tested on a Diesel Division, General Motors of Canada Generation III LAV chassis. As this was not available, a offer to test it on the ASCOD was accepted by General Dynamics. Over 70 rounds of ammunition were fired while the vehicle was stationary and moving with the target also moving.

The aim of the trials was to validate the improvements carried out to the latest Generation LPT system.
