The SPA-Viberti AS.42, officially known as Autoblindo Sahariana (Saharan Armoured Car) or Autoveicolo Sahariano (Saharan Vehicle), was an Italian reconnaissance and light combat vehicle developed during World War II. Designed specifically for desert operations, it was a collaborative effort between the Italian automotive manufacturer Società Piemontese Automobili (SPA) and the bodybuilder Viberti.
Development and Design
The AS.42 was developed in 1942 in response to the specific requirements of the Italian Army operating in the vast and challenging North African desert. The need was for a fast, long-range vehicle capable of reconnaissance, convoy escort, and engaging lightly armed targets. Its design was influenced by the British Long Range Desert Group (LRDG) vehicles and aimed to provide similar capabilities.
Based on the chassis of the SPA TL37 light truck, which itself was derived from the successful SPA TL37 artillery tractor, the AS.42 featured a distinctive open-top, low-profile body. This design facilitated easy crew entry and exit, provided good all-around visibility, and allowed for quick adaptation of various armaments. The vehicle was characterized by its four-wheel drive (4x4) capability, which provided good off-road mobility over sand and rough terrain. Large fuel tanks were incorporated to ensure the long operational range required for desert warfare. It was powered by a 100 hp (75 kW) SPA 18T engine, allowing for a respectable top speed on appropriate terrain.
Armament
The AS.42 was designed with flexibility in mind regarding its armament, allowing units to mount weapons based on operational needs and availability. Common configurations included:
- A 20 mm Breda 35 autocannon, an effective weapon against unarmored vehicles and infantry.
- One or more 8 mm Breda Modello 38 machine guns.
- Some vehicles were fitted with heavier weapons, such as the 47 mm 47/32 anti-tank gun, making them capable of engaging enemy armored cars and light tanks.
- Other improvised armaments included captured 20 mm Solothurn S-18/100 anti-tank rifles. Ammunition storage and additional equipment like jerry cans for fuel and water were integral parts of its design.
Operational History
The SPA-Viberti AS.42 entered service with the Italian Army in North Africa in 1942. It was primarily used by specialized reconnaissance units and compagnie Sahariane (Saharan companies), which operated deep behind enemy lines. Its speed, range, and adaptability made it valuable for disruptive raids, scouting, and patrolling.
Following the Allied invasion of North Africa (Operation Torch) and the eventual surrender of Italian forces there, many AS.42s were captured and some were subsequently used by British and French Free Forces. After the Italian armistice in September 1943, the vehicles remaining in Italy were utilized by German forces and the Italian Social Republic. Some units reportedly saw service on the Eastern Front, modified to suit the differing terrain.
Legacy
The AS.42, along with its successor, the AS.43, represented an important attempt by Italy to develop specialized vehicles for a specific theater of war. While relatively few were produced (estimates suggest around 300 units for both AS.42 and AS.43 combined), they demonstrated a pragmatic approach to mobile warfare in the desert environment. Surviving examples are rare but are valued by military history enthusiasts.
