The ASCOD (Austrian Spanish Cooperation Development)^[1] armoured fighting vehicle family is the product of a cooperation agreement between Austrian Steyr-Daimler-Puch AG and Spanish General Dynamics Santa Bárbara Sistemas. Both companies are now divisions of a unit of General Dynamics. The ASCOD family includes the LT 105 light tank equipped with a 105 mm gun, a surface-to-air missile launcher, an anti-tank guided missile launcher, mortar carrier, R&R vehicle, command-and-control vehicle, ambulance, artillery observer, and the AIFV model.

In Spanish service, the vehicle is called "Pizarro". The Austrian version is called "Ulan".

The ASCOD was designed to replace the older light armoured fighting vehicles of the Austrian and Spanish armies, such as the M113 armored personnel carrier and the Saurer APC. The Ulan, the Austrian version of the Pizarro, would provide a flexible complement to their heavy Leopard 2A4. The Ulan would allow the Austrian army to deploy rapidly and effectively over longer distances, especially for foreseeable future operations—such as trouble-spots for UN operations.^[2]

In 1982, Steyr-Daimler-Puch Spezialfahrzeug initiated the conception phase for the development of a new infantry fighting vehicle. This was followed by initial talks with the militaries of Greece, Norway and Switzerland to find the desired requirements for a new IFV. In 1985, the decision to develop a new IFV was made following the Bundesheer announcement of the military requirement for the Kampfschützenpanzer 90 (combat infantry fighting vehicle 90).^[3] Based on this, Steyr-Daimler-Puch Spezialfahrzeug started the conception of the vehicle. However, it was clear that Austria would not order new IFVs in the next years and that the development costs exceeded Steyr's budget.^[3]

Therefore, in 1988, a cooperation with the Spanish company Empresa National Santa Barbara S. A. was signed, which resulted in the development being renamed to ASCOD (Austrian Spanish Cooperative Development).^[3] Following this, the development of the ASCOD started. The hulls were manufactured in Spain. The ASCOD turrets were made by Steyr in Austria, based on the SP-30 turret design used on the scout version of the Pandur. In 1991, the first prototype was presented in 1991 in Sevilla.^[3] It was tested in 1992. Production began in 1996.^[4]

Initially, the design was a cooperation between Austrian Steyr-Daimler-Puch AG and the Hellenic ELVO, formerly Steyr Hellas, after signing the contract for the domestically contracted Leonidas 2 APC. The contract, activated in 1988, required Steyr-Daimler-Puch AG to follow Hellenic instructions, and to include parts already produced in Greece, such as the wheels, tracks, and smoke-grenade launchers based on those of the Leopard 1 tank. Also, the secondary MG-3 gun — a variant of the Mauser 30F — was constructed in Greece. Greece withdrew from the program in 1991 after a change of government, requiring Steyr-Daimler-Puch to find a new partner. The IFV in Hellenic service would have the name Alexander the Great. Greece donated its design rights to Steyr-Daimler-Puch as compensation for the 450 IFVs cancelled.^{[citation needed]}

Following the numerous changed requirements during the ASCOD's conception and development phases, the weight increased from the original 18.8 t to 25.2 t and finally 29.0 tonnes. The first prototype was trialled in Norway in 1993/94, but Norway decided to purchase the Swedish CV9030 instead.^[3] Following these trials, a slightly updated third prototype was built, essentially equalling the version offered as ASCOD to Austria, Spain and other countries. In 1994, Spain decided to order four pre-series vehicles after successful trials of the prototype. In 1996, Spain ordered 144 vehicles with the designation "Pizarro".^[3]

Austria's order for the first 112 ASCOD vehicles, "Ulan" in Austria, was delayed for financial reasons until May 1999. Four pre-series Ulan vehicles were given to the Austrian Bundesheer in April 2001 for the final qualification. The official handover happened in May 2001. In 2002, 28 Ulans were delivered. The next batch of 36 was delivered in 2003. In 2004 the order was completed.^[3] In contrast to the original prototypes, the Ulan was completely manufactured in Austria.^[3]

The ASCOD effectively brought Austrian and Spanish armour up to date. The Pizarro project was part of the greater Project CORAZA (Project Armour) to replace Spain's M113 APCs, M60A3s, and M110 artillery pieces.^[5] By 2005, the Austrian army was equipped with 112 Ulan vehicles^[2] and Spain with 144 (123 IFV and 21 C2V).^[6]

In 2004, the Spanish Ministry of Defence ordered another 212 Pizarros (170 IFV, 5 C2V, 28 artillery observation, 8 recovery, 1 engineering vehicle) for €707.5 million Euros,^[7] with up to 356 units total planned.^[8] By 2010 the cost of this second batch had increased to €845m.^[9]

The improved ASCOD 2 vehicle was chosen by the UK MoD in March 2010 as the common base platform for the Scout Specialist Vehicle, later renamed Ajax. This selection was the result of the UK's Specialist Vehicle Programme. Around 300 British engineers at General Dynamics UK's Oakdale facility began developing the Ajax from the ASCOD 2 after being awarded the contract in 2010.^[10][11] The ASCOD 2 Scout SV was to replace the CVR(T) family of vehicles, including the FV107 Scimitar, the FV103 Spartan and the FV106 Samson armoured recovery vehicle.

General Dynamics offered the ASCOD 2 in an APC configuration in the competition for the Danish M113 replacement. The ASCOD 2 was not chosen. The Danish army preferred the wheeled Piranha 5.^[12]

ASCOD entered service with the Spanish and Austrian armies in 2002.^[8] The British Army received its first ASCOD SV in 2020.^[13] Despite being part of ISAF, Spain did not deploy the Pizarro IFV owing to its lack of a mine-protection kit.

The primary version of the ASCOD is the tracked infantry-fighting vehicle. It follows a conventional layout, featuring a front-mounted engine and a rear compartment for the dismounts. The driver's seat is located at the left hull front. The commander and gunner sit in the slightly off-center–mounted two-man turret. The rear compartment has two hatches on the roof. The Ulan can carry eight dismounts.^[14] The Pizarro carries seven.^[15]

The ASCOD mounts a 30 mm Mauser MK-30/2 autocannon in a fully traversable electro-mechanical turret. The dual belt-fed 30 mm cannon, electrically stabilized on two planes, is able to fire at a rate of up to 770 rounds per minute and accurately engage targets on the move.^[3] As secondary armament, the ASCOD carries a 7.62 mm machine gun. The Spanish Pizarro is fitted with an MG-3 machine gun. The Ulan is fitted with an FN MAG. The Ulan carries 200 rounds of 30 mm and 600 rounds of 7.62 mm in the turret. A further 205 rounds for the 30 mm gun and up to 1,290 for the 7.62 mm machine gun are stored inside the hull.^[3] The Pizarro carries 300 rounds of main-gun ammunition.^[15]

This armament is comparable to that of the M2 Bradley and the CV90, and performed well in a Norwegian vehicles trial, although it ultimately lost to the Swedish CV90.

The Ulan is fitted with a digital fire-control system built by Kollsman,^[8] utilising some components of the Kürassier A2's fire control system.^[3] The gunner's sight is manufactured by Elbit and provides 8× magnification in the day channel. The integrated thermal imager, featuring 2.8× and 8.4× magnification, can be accessed by both the gunner and the commander. The commander has a fixed day-sight with 8× magnification.^[3] The Pizarro uses the Mk-10 fire control system from Indra, featuring a full-solution digital ballistic computer, day channel, thermal channel and laser rangefinder. Future versions of the Mk-10 will be fitted with a new VC2 thermal imager.^[8]

The ASCOD is constructed of several rolled steel armour plates. The armour provides protection against 14.5 mm armour-piercing ammunition fired from distances of 500 meters or more along the frontal 60° arc,^[16][17] with all-round protection against 7.62 mm ammunition.^[8] The turret is fitted with two banks of 76 mm Wegmann multi-purpose grenade launchers. These can fire smoke grenades for self-protection, or high-explosive grenades with fragmentation warhead to a maximum range of 50 metres (160 ft).^[3]

The Pizarro is additionally fitted with limited amounts of SABBLIR explosive reactive armour along the frontal arc and might be upgraded with more later.^[4] The SABBLIR reactive armour increases protection against shaped-charge warheads as used on rocket-propelled grenades. The Ulan has been fitted with MEXAS composite armour,^[18] which increases ballistic protection against up to 30 mm APFSDS rounds fired from a 1,000 m range over the forward 30° arc, and all-round protection against 14.5 mm armour piercing incendiary (API) rounds from a range of 500 m.^[3] The Ulan is fitted with spall-liners to minimise casualties in case of armour penetration.^[3]

In terms of mobility, the Spanish Pizarro is fitted with a 600 horsepower (450 kW) MTU SV-183 TE22 engine, while the Austrian Ulan includes a 720 horsepower (540 kW) MTU 8V-199-TE20 engine. These have power-to-weight ratios of 21 and 25, respectively, offering both vehicles excellent mobility. Both versions use a Renk HSWL 106C hydro-mechanical transmission, and suspension — based on torsion bars^[8] and rotary dampers — designed and manufactured by "Piedrafita".^[19]

The ASCOD uses Diehl type-129 tracks.^[20] The Pizarro has a maximum speed of 70 km/h, and a maximum reverse speed of 35 km/h.^[3][4] The ASCOD has a ground-clearance of 450 millimetres (18 in). The Ulan can accelerate from 0 to 50 kilometres per hour (31 mph) in 14 seconds. It can cross ditches of 2.3 metres (7 ft 7 in), climb walls of 950 millimetres (37 in) and ford rivers of 1.2 metres (3 ft 11 in) depth. It is able to drive at 75% gradient and 40% side slope.^[3]

The ASCOD chassis has been used for a number of vehicles in Spanish service and numerous private ventures developed for the export market. Aside from the IFV version, the ASCOD has been offered as light tank and scout vehicle.^[21][22] The ASCOD Direct Fire light tank can mount a number of different commercial turrets with 105 or 120 mm tank guns. It is expected to weigh about 30 tonnes.

Steyr-Daimler-Puch Spezialfahrzeuge has developed an improved version called Ulan 2. This was never ordered by the Austrian government.^[23]

An improved version of the ASCOD, called ASCOD 2, has been developed by General Dynamics and was presented in 2004. The ASCOD 2 uses the more powerful MTU 8V 199T21 engine, which provides a 600 kilowatts (800 hp) output, together with a Renk HSWL 256 B transmission and Diehl 1028 tracks.^[20] It has an increased gross vehicle weight of 38 tons, with a growth potential to 42 tons. The ASCOD 2 has been presented as an IFV (with the SP-30 turret of the original ASCOD), as an APC with a raised roof and armed with an M2 machine gun (in a BAE Lemur remote weapon station)^[24] and as a specialized APC for urban combat (designated the ASCOD PSO).^[20]

In June 2008, GDELS, in conjunction with KMW, announced Donar, a medium-weight 155 mm self-propelled artillery system based on the KMW Artillery Gun Module (AGM) autonomous artillery system, integrated with the ASCOD 2 chassis. A prototype has begun mobility and firing trials in Germany.^[25][26]

In March 2010, the UK MoD announced that ASCOD 2 will be used as the base for the Scout Specialist Vehicle of the FRES program,^[27] which was later renamed to "Ajax".

At Eurosatory 2018, General Dynamics European Land Systems presented a new variant of the ASCOD 2. The ASCOD medium main battle tank (MMBT), with a gross vehicle weight of 42 tonnes, is fitted with the Italian Leonardo Defence Systems HITFACT 120 mm turret. This is armed with a 7.62 mm coaxial machine gun, a 7.62 mm pintle-mounted gun and a 12.7 mm remote weapon station on the roof. The 120 mm smoothbore gun is coupled to a computerised fire control system, with the commander and gunner having stabilised day/thermal sights incorporating a laser rangefinder.^[28]

• ASCOD 2 MMBT – As the name suggests, it is intended as a medium main battle tank armed with either a 120 mm or 105 mm HITFACT turret.^[28]

The ASCOD vehicle was chosen by the UK MoD as the common base platform on which the Ajax would be developed. This selection was the result of the UK's Specialist Vehicle Programme. Around 300 British engineers at General Dynamics UK's Oakdale facility began developing the Scout from the ASCOD after being awarded the contract in 2010.^[10][11]

These vehicles are the replacements for the CVR(T) family vehicles: FV107 Scimitar (armoured reconnaissance), FV103 Spartan (specialist personnel carrier) and FV106 Samson (recovery vehicle).

Recce Block 2 is expected to include ambulance, engineer reconnaissance and command & control replacements for the CVR(T) FV104 Samaritan (armoured ambulance) and FV105 Sultan (command vehicle).

The Ajax is planned to include the following upgrades:^[30]

• The main weapon will be a 40 mm autocannon with "telescoped ammunition" (CT40 cannon).
• The armour will provide basic ballistic and mine protection, with upgrade add-on packages for improved protection when needed.
• The chassis will be upgraded with enhanced suspension combining torsion bars and hydraulic dampers.
• An enhanced powertrain comprising a 600 kW (805 bhp) MTU V8 199 diesel engine and Renk 256B fully automatic transmission.
• The welded turret will be built by Lockheed Martin UK.
• Assembly and testing will take place in the UK^[31]

The vehicle's normal combat weight is 34 tonnes.

The ASCOD Pizarro is built by GDELS Santa Bárbara Sistemas, and operated by the Spanish Army. It exists in multiple variants.^[4]
