Pak 38

Pak 38 The 7.5 cm Pak 38 was a German towed anti-tank gun introduced during World War II to counter newer Soviet tanks and replace earlier models. It saw service with the Wehrmacht, Waffen-SS, and allied formations across the Eastern Front, Western Front, and North African Campaign. The design balanced mobility from a split-trail carriage with a longer, high-velocity barrel to fire kinetic and shaped-charge projectiles.

Development and Design

Development began as part of interwar German efforts at Rheinmetall-Borsig and Krupp to improve anti-tank capabilities following encounters like the Spanish Civil War and intelligence on Soviet Union armored programs. Designers sought a middle ground between the lighter 3.7 cm and heavier 8.8 cm weapons used by units such as the Heer and Waffen-SS. Trials considered influences from captured French Army and Czechoslovakia designs and lessons from the Battle of France. Engineers prioritised a long 75 mm L/46 barrel, a horizontal sliding-wedge breech adopted from earlier German ordnance, and a split-trail carriage to increase traverse for combined-arms coordination with units like the Panzerwaffe and Fallschirmjäger anti-tank detachments. Industrial production involved firms including Rheinmetall, Krupp, and private subcontractors mobilised under Reichsministerium für Bewaffnung und Munition policies.

Technical Specifications

The gun fired a 75×490mm R cartridge and used a horizontal sliding-block breech with semi-automatic extraction similar to contemporary designs fielded by the British Army and United States Army. Barrel length (L/46) produced muzzle velocities near 792 m/s with APCBC rounds and higher with APCR ammunition developed in response to T-34 and KV-1 armour. The split-trail carriage allowed 60° traverse and elevation from −8° to +27°, facilitating engagement across features encountered in operations like Operation Barbarossa and the Battle of Kursk. Gun shield protection mirrored trends seen in weapons used by Italian Army and Hungarian Armed Forces allies. Ammunition types included APCBC, APCR, HE, and later the 75 mm hollow-charge round inspired by developments elsewhere in Germany's munitions sector and comparable to shaped-charge work by Italian, British, and American researchers.

Operational History

Introduced in 1940–1941, the gun entered service with anti-tank battalions of the Heer and Waffen-SS formations during Operation Barbarossa and subsequent Eastern Front campaigns. Units employed it in defensive belts during events such as the Siege of Leningrad, Battle of Moscow, and counterattacks around Kharkov and Stalingrad. Western deployments saw use in the Italian Campaign, the Battle of Normandy, and the later defensive battles during the Allied invasion of Germany. Captured examples were used by the Red Army, French Forces of the Interior, British Army units in limited roles, and German-occupied coast defenses opposing the Normandy landings. Production continued despite shifting priorities to heavier weapons like the 8.8 cm Pak 43 and to self-propelled mounts such as the successors used by Panzerjäger formations.

Variants and Modifications

Field modifications ranged from carriage adaptations to enable towing by vehicles like the Sd.Kfz. 7 half-track and conversion into self-propelled mounts on chassis such as the Marder II and Marder III. Anti-tank companies experimented with enhanced muzzle brakes, modified gun shields, and specialized mounting kits for coastal batteries used by Kriegsmarine shore detachments and Festung units. Several captured and allied workshops produced rechambered or rebored examples for use by Hungarian Army, Romanian Army, and Croatian Legion formations. Later-war shortages prompted improvisations similar to those employed with the Pak 36 and the 7.5 cm PaK 40, influencing logistic interchangeability with ammunition stocks of units from Italy to Finland.

Combat Use and Effectiveness

Combat experience showed the gun to be effective against early T-34 variants at combat ranges with APCBC rounds and highly effective with APCR rounds against heavier Soviet armour during engagements like the Battle of Kursk and the Second Battle of Kharkov. It proved more mobile than the 8.8 cm Pak 43 and more potent than captured light anti-tank pieces such as the Hotchkiss 25 mm. However, by 1943–1944, increasing thickness and sloped armour on Allied tanks reduced its battlefield dominance, prompting emphasis on heavier ordnance and increased use of shaped-charge warheads. Tactical employment evolved: deployed in concealed anti-tank ambushes by units from the Heer and Waffen-SS, integrated into combined-arms defenses with Sturmgeschütz support, and used in urban fighting in cities like Kiev and Warsaw. Postwar, surviving pieces served in limited roles with several European armies and in museum collections documenting the evolution of anti-tank artillery.
