The Panzerkampfwagen IV (PzKpfw IV), commonly known as the Panzer IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161.

The Panzer IV was the most widely manufactured German tank and the second-most widely manufactured German armored fighting vehicle of the Second World War, with some 8,500 built. The Panzer IV chassis was used as the base for many other fighting vehicles, including the Sturmgeschütz IV assault gun, Jagdpanzer IV tank destroyer, the Wirbelwind self-propelled anti-aircraft gun, and the Brummbär self-propelled gun.

The Panzer IV saw service in all combat theaters involving Germany and was the only German tank to remain in continuous production throughout the war. It received various upgrades and design modifications, intended to counter new threats, extending its service life. Generally, these involved increasing the Panzer IV's armor protection or upgrading its weapons, although during the last months of the war, with Germany's pressing need for rapid replacement of losses, design changes also included simplifications to speed up the manufacturing process.

The Panzer IV was partially succeeded by the Panther medium tank, which was introduced to counter the Soviet T-34, although the Panzer IV continued as a significant component of German armoured formations to the end of the war. The Panzer IV was the most widely exported tank in German service, with around 300 sold to Finland, Romania, Spain and Bulgaria. After the war, Syria procured Panzer IVs from France and Czechoslovakia, which saw combat in the 1967 Six-Day War. 8,553 Panzer IVs of all versions were built during World War II, with only the StuG III assault-gun/tank destroyer's 10,086 vehicle production run exceeding the Panzer IV's total among Axis armored forces.

Development history


The Panzer IV was the brainchild of the German general and innovative armored warfare theorist Heinz Guderian.[6] In concept, it was intended to be a support tank for use against enemy anti-tank guns and fortifications.[7] Ideally, each tank battalion in a panzer division was to have three medium companies of Panzer IIIs and one heavy company of Panzer IVs.[8] On 11 January 1934, the German army wrote the specifications for a "medium tractor", and issued them to a number of defense companies. To support the Panzer III, which would be armed with a 37-millimetre (1.46 in) anti-tank gun, the new vehicle would have a short-barreled, howitzer-like 75-millimetre (2.95 in) as its main gun, and was allotted a weight limit of 24 tonnes (26.46 short tons). Development was carried out under the name Begleitwagen ("accompanying vehicle"),[9] or BW, to disguise its actual purpose, given that Germany was still theoretically bound by the Treaty of Versailles ban on tanks.[10] MANKrupp, and Rheinmetall-Borsig each developed prototypes,[8] with Krupp's being selected for further development.[11]

The chassis had originally been designed with a six-wheeled Schachtellaufwerk interleaved-roadwheel suspension (as German half-tracks had already adopted), but the German Army amended this to a torsion barsystem. Permitting greater vertical deflection of the roadwheels, this was intended to improve performance and crew comfort both on- and off-road.[11][12] However, due to the urgent requirement for the new tank, neither proposal was adopted, and Krupp instead equipped it with a simple leaf spring double-bogie suspension, with eight rubber-rimmed roadwheels per side.

The prototype required a crew of five men; the hull contained the engine bay to the rear, with the driver and radio operator, who doubled as the hull machine gunner, seated at the front-left and front-right, respectively. In the turret, the tank commander sat beneath his roof hatch, while the gunner was situated to the left of the gun breech and the loader to the right. The turret was offset 66.5 mm (2.62 in) to the left of the chassis center line, while the engine was moved 152.4 mm (6.00 in) to the right. This allowed the torque shaft to clear the rotary base junction, which provided electrical power to turn the turret, while connecting to the transmission box mounted in the hull between the driver and radio operator. Due to the asymmetric layout, the right side of the tank contained the bulk of its stowage volume, which was taken up by ready-use ammunition lockers.[11]

Accepted into service as the Versuchskraftfahrzeug 622 (Vs.Kfz. 622),[10] production began in 1936 at Fried. Krupp Grusonwerk AG factory at Magdeburg.[13]

Ausf. A to Ausf. F1

Panzer IV Ausf. C 1943

The first mass-produced version of the Panzer IV was the Ausführung A (abbreviated to Ausf. A, meaning "Variant A"), in 1936. It was powered by Maybach's HL 108TR, producing 250 PS (183.87 kW), and used the SGR 75 transmission with five forward gears and one reverse,[14] achieving a maximum road speed of 31 kilometres per hour (19.26 mph).[15] As main armament, the vehicle mounted the short-barreled, howitzer-like 75 mm (2.95 in) Kampfwagenkanone 37 L/24 (7.5 cm KwK 37 L/24) tank gun, which was a low-velocity weapon mainly designed to fire high-explosive shells.[16] Against armored targets, firing the Panzergranate (armor-piercing shell) at 430 metres per second (1,410 ft/s) the KwK 37 could penetrate 43 millimetres (1.69 in), inclined at 30 degrees, at ranges of up to 700 metres (2,300 ft).[17] A 7.92 mm (0.31 in) MG 34 machine gun was mounted coaxially with the main weapon in the turret, while a second machine gun of the same type was mounted in the front plate of the hull.[11] The main weapon and coaxial machine gun were sighted with a Turmzielfernrohr 5b optic while the hull machine gun was sighted with a Kugelzielfernrohr 2 optic.[18] The Ausf. A was protected by 14.5 mm (0.57 in) of steel armor on the front plate of the chassis, and 20 mm (0.79 in) on the turret. This was only capable of stopping artillery fragmentssmall-arms fire, and light anti-tank projectiles.[19]

After manufacturing 35 tanks of the A version, in 1937 production moved to the Ausf. B.[10] Improvements included the replacement of the original engine with the more powerful 300 PS (220.65 kW) Maybach HL 120TR, and the transmission with the new SSG 75 transmission, with six forward gears and one reverse gear. Despite a weight increase to 16 t (18 short tons), this improved the tank's speed to 42 kilometres per hour (26.10 mph).[20] The glacis plate was augmented to a maximum thickness of 30 millimetres (1.18 in),[19] while a new driver's visor was installed on the straightened hull front plate, and the hull-mounted machine gun was replaced by a covered pistol port and visor flap.[20] The superstructure width and ammunition stowage were reduced to save weight.[20] A new commander's cupola was introduced which was adopted from the Panzer III Ausf. C.[20] A Nebelkerzenabwurfvorrichtung (smoke grenade discharger rack) was mounted on the rear of the hull starting in July 1938[20] and was back fitted to earlier Ausf. A and Ausf. B chassis starting in August 1938.[21] Forty-two Panzer IV Ausf. Bs were manufactured before the introduction of the Ausf. C in 1938.[10][22] This saw the turret armor increased to 30 mm (1.18 in), which brought the tank's weight to 18.14 t (20.00 short tons).[22] After assembling 40 Ausf. Cs, starting with chassis number 80341, the engine was replaced with the improved HL 120TRM. The last of the 140 Ausf. Cs was produced in August 1939, and production changed to the Ausf. D; this variant, of which 248 vehicles were produced, reintroduced the hull machine gun and changed the turret's internal gun mantlet to a 35 mm (1.38 in)[23] thick external mantlet.[22]Again, protection was upgraded, this time by increasing side armor to 20 mm (0.79 in).[16] As the German invasion of Poland in September 1939 came to an end, it was decided to scale up production of the Panzer IV, which was adopted for general use on 27 September 1939 as the Sonderkraftfahrzeug 161 (Sd.Kfz. 161).[10]

In response to the difficulty of penetrating the armor of British infantry tanks (Matilda and Matilda II) during the Battle of France, the Germans had tested a 50 mm (1.97 in) gun—based on the 5 cm Pak 38 anti-tank gun—on a Panzer IV Ausf. D. However, with the rapid German victory in France, the original order of 80 tanks was canceled before they entered production.[24]

In October 1940, the Ausf. E was introduced. This had 30 millimetres (1.18 in) of armor on the bow plate, while a 30-millimetre (1.18 in) appliqué steel plate was added to the glacis as an interim measure. A new driver's visor, adopted from the Sturmgeschütz III was installed on the hull front plate.[25] A new commander's cupola, adopted from the Panzer III Ausf. G, was relocated forward on the turret eliminating the bulge underneath the cupola.[26] Older model Panzer IV tanks were retrofitted with these features when returned to the manufacturer for servicing. 206 Ausf. Es were produced between October 1940 and April 1941.[3]

The short-barreled Panzer IV Ausf. F1.

In April 1941, production of the Panzer IV Ausf. F started. It featured 50 mm (1.97 in) single-plate armor on the turret and hull, as opposed to the appliqué armor added to the Ausf. E,[22] and a further increase in side armor to 30 mm (1.18 in).[27] The main engine exhaust muffler was shortened and a compact auxiliary generator muffler was mounted to its left.[25] The weight of the vehicle was now 22.3 tonnes (24.6 short tons), which required a corresponding modification of track width from 380 to 400 mm (14.96 to 15.75 in) to reduce ground pressure. The wider tracks also facilitated the fitting of track shoe "ice sprags", and the rear idler wheel and front sprocket were modified.[28] The designation Ausf. F was changed in the meantime to Ausf. F1, after the distinct new model, the Ausf. F2, appeared. A total of 471 Ausf. F (later temporarily called F1) tanks were produced from April 1941 to March 1942.[3]
