Galerie de photos d’un SturmHaubitze 42, En 1942, une variante de la StuG III Ausf. F a été conçu avec un obusier de 105 mm (4,1 po) au lieu du canon StuK 40 L/43 de 7,5 cm. Ces nouveaux véhicules, désignés StuH 42 (Sturmhaubitze 42, Sd.Kfz 142/2), ont été conçus pour fournir un soutien d’infanterie avec le nombre accru de StuG III Ausf. F/8 et Ausf. Gs utilisés dans le rôle antichar. Le StuH 42 a monté une variante de l’obusier leFH 18 de 10,5 cm, modifié pour être tiré électriquement et équipé d’un frein à museau. Des modèles ultérieurs ont été construits à partir de StuG III Ausf. Châssis G ainsi que StuG III Ausf. F et Ausf. Châssis F/8. Le frein museau a souvent été omis en raison de la rareté des ressources plus tard dans la guerre. 1 211 StuH 42 ont été produits d’octobre 1942 à 1945.

Lla Sturmhaubitze 42 was the brute-force sibling of the StuG III. While the standard StuG evolved into a high-velocity tank destroyer, the German infantry still needed a vehicle that could lob heavy high-explosive shells to destroy bunkers and fortified buildings. The solution was to take the StuG III chassis and replace the 7.5cm anti-tank gun with a modified 10.5cm leFH 18 howitzer. It looked nearly identical to its brother, but its short, fat barrel signaled a much bigger boom, making it the perfect tool for clearing out street corners and entrenched « Ivan » positions.

Design Engineering: Low Profile, Big Caliber
- The Howitzer Conversion: To fit the massive 10.5cm gun into the StuG’s cramped cabin, engineers had to redesign the recoil system. Early models featured a large, double-baffle muzzle brake to help manage the violent kick of the bigger shell.
- Two-Part Ammunition: Unlike the 7.5cm StuG which used single-piece shells, the StuH 42 used separate loading (projectile and then the casing with powder). This made the rate of fire slightly slower, but allowed the loader to change the « charge » to adjust the shell’s trajectory for firing over obstacles.
- Interchangeable Parts: Because it shared the chassis, engine, and transmission with the StuG III and Panzer III, maintenance in the field was remarkably easy. Parts could be scavenged from broken StuGs to keep the heavy howitzers rolling.
- Concrete Armor: It wasn’t uncommon to see StuH 42 crews add layers of beton (concrete) to the front of their vehicles. While it added weight, it helped protect against the Soviet anti-tank rifles that plagued the low-slung assault guns.
Operational History: Breaking the Stalemate
- The Siege Specialist: The StuH 42 was most effective in urban combat. During the retreat through Italy and the fighting in Normandy, one 10.5cm HE shell could collapse an entire house used by Allied snipers, whereas the 7.5cm StuG might just punch a clean hole through it.
- Anti-Tank Capability: While not its primary job, the StuH 42 carried Hollow Charge (HEAT) rounds. These could penetrate roughly 100mm of armor, meaning the « Infantry Sledgehammer » could still knock out a T-34 or a Sherman if it had to.
- Lla « Saukopf » Evolution: Like the late-war StuG, many StuH 42s received the cast « Pig’s Head » mantlet, which was more aerodynamic and better at deflecting enemy shells than the original boxy design.
- Rare Survival: Only a few StuH 42s survived the war. Because they were usually at the very front of an assault, their attrition rate was high, but their contribution to keeping German infantry from being pinned down was immeasurable.
