Pz. Kpfw. III Aus. A, B, C, D, E (Sd. Kfz. 141): Medium Tanks

Pz. Kpfw. III Aus. A, B, C, D, E (Sd. Kfz. 141): Medium Tanks

Reports on the early development of the Pz. Kw. III do not agree. The following summary conforms to the best information available.

Model A—Weighed about 20 tons. Its suspension arrangement consisted of eight small bogie wheels each side on semi-elliptical, laminated springs, with three return rollers. Motivating power was generated by a Maybach V-12 gasoline engine rated 300 hp. Armament consisted of a 3.7 cm Kw. K., two light machine guns in the turret, and one light machine gun in the front plate of the superstructure. Armor consisted of 30 mm plate all around.

Model B—Same as Mode] A except for suspension which consisted of five medium size bogie wheels and two return rollers.

Model C—Principal change was the new type suspension which incorporated six bogie wheels and three return rollers, which became standard for the Pz. Kw. III tank. It is believed that torsion bar suspension evolved in this model.

Model D1—At this point in the development the previous models were given the nomenclature D1. Commander’s tanks are known to have been produced serially from this period on.

Model E—Represents the first model in which the definite Pz. Kw. III type has been crystallized. It embodies the improvements made in previous models. It carried the same armament (3.7 cm Kw. K.) and had a suspension arrangement of six bogie wheels sprung on torsion bars and three return rollers.

A self-propelled equipment known as the Sturmgeschütz has been developed from the Pz. Kw. III. It consists of the Pz. Kw. III chassis mounting a short-barreled 7.5 cm Kw. K. The chassis was later used to mount the 7.5 cm Kw. K. 40, long-barreled gun, and the 10.5 cm howitzer.

Pz. Jäg. 38 für 7.5 cm Pak 40/3 (Sd. Kfz. 138): S.P. Antitank Gun (on Czech Chassis)

Pz. Jäg. 38 für 7.5 cm Pak 40/3 (Sd. Kfz. 138): S.P. Antitank Gun (on Czech Chassis)

The equipment consists of the 7.5 cm Pak 40 mounted on a turretless chassis of a Pz. Kpfw. 38 (t) tank of Czech origin, formerly known as the L.T.H. This mount was used by the Germans in large numbers on the Russian front. It usually moves just in the rear of the first wave of tanks. Its road performance approximates that of the Pz. Kpfw. 38 (t) tank.

Due to the bolted construction of the parent vehicle the removal of the turret, superstructure top plate and the engine access hatches of the original tank is readily accomplished and the mounting of the anti-tank gun is speedily performed. The turntable of the anti-tank gun is bolted to the angle section formerly carrying the superstructure top plate of the original tank. The gun shield is constructed from 10-15 mm plate. It is open at the top and rear. The protection afforded the crew is little better than would be found on a field piece.

The gun, which projects well beyond the front of the hull, is of monobloc, loose barrel construction, and is fitted with a double baffle muzzle brake. The breech ring is rectangular and is secured to the barrel by a loose screwed collar. The recoil mechanism is attached underneath the ring by a detachable lug. The elevating and traversing mechanisms are controlled by hand wheels. The gun has the following muzzle velocities: HE 1800 f.s.; A.P.C., 2525 f.s; hollow charge 1476 f.s. The A.P.C. shell will penetrate homogeneous armor as follows: 500 yards 4.0 ins. at 30° obliquity, 4.8 ins. normal—1000 yards 3.6 ins. at 30°, 4.3 ins. normal—2000 yards 2.8 ins. at 30°, 3.4 ins. normal—2500 yards 2.5 ins. at 30°, 3.0 ins. normal. The gun has a traverse of 65° and an elevation of -5° to + 22°.

Sturmgeschüz 10.5 cm Stu. H. 42 (Sd. Kfz. 142/2): S.P. Assault Gun

Sturmgeschüz 10.5 cm Stu. H. 42 (Sd. Kfz. 142/2): S.P. Assault Gun

The vehicle is a combination of the Pz. Kpfw. III tank chassis and the 10.5 cm l.F.H. 18 (M) with muzzle brake.

The squat superstructure which replaced the turret of the original tank is similar to the Stu. K. 40. Motor, track, and other chassis mechanisms are the same as those in the standard Pz. Kpfw. III tank and its performance should nearly approximate that vehicle.

The howitzer, Stu. H. 42, is identical to the 10.5 cm l.F.H. 18 (M), except that the former is electrically fired and has the following radius of movement: traverse 20°; elevation -6° to +20°. The piece has a length of 115.75 inches excluding the muzzle brake, which is approximately 15 inches in length. The weight of the gun and cradle is 1.7 tons. Firing a long range shell with supercharge, its muzzle velocity is 1,770 f.s. and its maximum range is 13,480 yards. It fires the 32.6 lb. H.E. shell, a long range H.E. shell, a 32.51 lb. smoke shell, a 25.9 lb. hollow charge shell, and an H.E./incendiary shell.

Auxiliary armament consists of 2 machine pistols, 18 egg grenades, and 1 signal pistol. There are no coaxially mounted or free-mounted machine guns.

The Germans have recently begun attaching thin skirting armor plate of from 5 mm to 8 mm thickness on various fighting vehicles, including the Sturmgeschütz. The following theories have been advanced for this development: (1) to break up or deflect 20 mm tungsten carbide core ammunition; (2) to defeat hollow charge shells; (3) to defeat the 14.7 mm Russian antitank rifle; (4) to defeat the American Bazooka.

Pz. Kpfw. IV Aus. F1, F2, G, H, K (Sd. Kfz. 161): Medium Tanks

Pz. Kpfw. IV Aus. F1, F2, G, H, K (Sd. Kfz. 161): Medium Tanks

Model F—The hull, superstructure, and turret, as in all other known models of the Pz. Kpfw. IV, is of welded construction. The basic frontal armor, including superstructure and turret of Model F, was increased to 50 mm; on the sides to 30 mm. The main hull superstructure projects over the top of the tracks, providing additional stowage space and a wide base upon which to mount the turret. The turret floor is carried by brackets from the turret ring and consequently rotates with the turret.

The suspension consists of 4 bogie assemblies, each fitted with two rubber-tired bogie wheels 18 1/2 inches in diameter on each side, with a quarter elliptic spring anchored beneath the leading axle arm of each assembly. There is a front sprocket, the spokes of which are bent outward from the hub cap giving the outside a dished appearance, a rear idler which has 7 spokes instead of 8 as in previous models, and 4 return rollers.

The power plant consists of a Maybach HL 120 TRM, V-12 O.H.V., 4-stroke, gasoline engine, rated 320 B.H.P. at 3,000 r.p.m.

The armament consists of a 7.5 cm Kw. K., 24 cals. in length, a coaxial 7.92 mm MG 34 mounted in the turret, and a 7.92 mm MG 34 at the right of the front plate of the superstructure.

Model F2—Same as Model F except that it carried the initial experimental mounting of the Kw. K. 40, 43 cals. in length.

Model G—Produced in 1942. Same as Model F except that the mounting of the Kw. K. 40 was continued. The gun was fitted with a double baffle muzzle brake.

Models H, K—These models are referred to in German documents published during 1943.

2 cm Flak 38: A.A./A.T. Gun

2 cm Flak 38: A.A./A.T. Gun

The Flak 38 was introduced in 1940 to replace the 2 cm Flak 30. Its performance does not differ materially from that of the earlier weapon, except for a higher cyclic rate of fire of 450 rounds per minute.

The gun is operated by short barrel recoil and the residual pressure of gas in the barrel. Recoil unlocks the breech and imparts rearward acceleration to the breechblock carrier. This rearward acceleration is assisted by gas pressure after unlocking has been completed so that the breechblock travels back with sufficient force to perform the operations of extraction, ejection, and compression of the return spring.

The energy required for closing the breech and carrying a fresh round to the chamber is provided by the return spring, assisted at first by the buffer spring.

The breechblock is of the Solothurn type. Any tendency toward rebound is counteracted by the impact of an inertia block at the end of the forward movement. The barrel has resistance rings which brake the recoil and forward movements of the barrel; a buffer and buffer spring arrest the backward movement of the breech block.

This weapon may be adjusted for either semi-automatic or full-automatic fire. It is fired by a foot pedal. Cartridges are fed from a 20-round curved box magazine hinged on the left of the gun.

The mounting consists principally of the base, cradle, traversing and elevating gears, firing mechanism, and lighting equipment.

Traverse is 10° per turn of handwheel in fine gear and 30° in coarse gear; rate of elevation or depression is 4° per turn in fine gear and 12° in coarse gear.

The weapon, which is transported on a trailer, may be mounted on railways cars or road vehicles. When traveling over difficult country, gun and mounting may be split into six loads.

2 cm Flak 30: Antiaircraft Gun

2 cm Flak 30: Antiaircraft Gun

The Flak 30 was the principal armament of German light antiaircraft units since the beginning of the war in Europe until the introduction of the 2 cm Flak 38 and 2 cm Flak 38 Vierling. The gun, which may be mounted on road or railway vehicles, is normally transported on a single-axle trailer which is drawn by either horse or motor vehicle. It is usually fired with its mounting on the ground and with the trailer removed. However, it can be fired from the trailer at both ground or aerial targets in emergencies.

This recoil-operated weapon is fed by a flat 20-round box magazine. The trigger mechanism is pedal-actuated; operation is either full-automatic or semi-automatic.

The barrel slides in the body with the barrel extension. A combined muzzle brake and flash eliminator is screwed to the muzzle and retained by a catch. The barrel extension is slotted on the right and left sides for ejection and feed respectively.

The body is formed to receive the barrel extension, which is hinged near the rear end of the body. The barrel return spring, buffer spring, buffer, and rod and sleeve are housed in a casing secured to the body at the rear.

The sights used are the Flakvisier 35, and the Linealvisier 21, the former is of the reflecting-mirror type with a data-calculating mechanism; the latter is a direct antiaircraft sight embodying course, speed, and range adjustment.

The gun carriage consists of a firm under carriage and a revolving top carriage supported on ball bearings. The under carriage is leveled by three adjustable feet, and is provided with a spirit level. The top carriage has a cradle which is adjustable for elevation. The elevation handwheel is located on the right side of the top carriage, and the traversing handwheel at the back.

Pz. Kpfw. 38 (t): Light Tank (Czech)

Pz. Kpfw. 38 (t): Light Tank (Czech)

This is the Czech tank L.T.H. The chassis of this vehicle is frequently converted by the Germans for use as a self-propelled mount for artillery pieces, such as the 7.5 cm. Pak 40 and 7.62 cm. Pak 36 (r) anti-tank guns, and the 15 cm. s.I.G. 33. The primary characteristics of the Pz. Kpfw. 38 (t) are its four large Christie-type bogie wheels of equal size; two top rollers forward; flat-topped turret with prominent cupola, and a square gun mantlet covering the whole front of the turret.

The turret is round with a square front. It has a traverse of 360° and an internal diameter of about 48 inches. Its floor does not revolve. The traversing gear, which is fast and light in action, is operated by a wheel on the left-hand side of the gunner. The bulge at the rear of the turret is fitted for ammunition storage.

All main construction is riveted with the exception of the top of the superstructure, which is bolted. The turret front has a basic armor of 25 mm with an additional 25 mm plate. The front vertical plate is similarly armored; the side superstructure armor is 30 mm in thickneses.

The suspension consists of four 30-inch diameter rubber-tired wheels on two bogies with half elliptic springs, a high front sprocket 22 1/4 inches in diameter and a rear idler. There are two return rollers mounted well forward. The track is of the outside center guide type, with single pin secured by circular clip.

The tank is powered by a Praga T.N.H.P.S. O.H.V. 6-cylinder, water-cooled, gasoline engine, rated 125 h.p. at 2200 r.p.m. The ignition is Bosch magneto.

The armament consists of a 3.7 cm. gun and one light machine gun coaxial in the turret, and one light machine gun in the front superstructure.

Mun. Trsp. Kw. Auf. Lr. S.: Ammunition Carrier (on French Lorraine Chassis)

Mun. Trsp. Kw. Auf. Lr. S.: Ammunition Carrier  (on French Lorraine Chassis)

The chassis of this vehicle is divided into the driving compartment at the front, the engine compartment in the center and an open-welled tray at the rear. The driving and engine compartments are armored on the sides and top; the rear compartment is armored on the sides only. The superstructure plates over the driving and engine compartments are bolted, whereas the sides of the rear superstructure are of riveted construction. With the exception of the cast nose plate and pressed steel cover, all the plates are flat and are riveted or bolted together over angle sections. There are no formed plates or welded joints. The armor thickness of the original carrier is as follows: Nose of hull 12 mm; front sloping plate 9.5 mm; sides 9 mm; back 9 mm.

The chassis is suspended from three semi-elliptical leaf springs on each side. The load is transmitted from the central point of each spring through supporting members to each of three pairs of bogies on each side. The bogie wheels are of the single, rubber-tired type 17.5 inches in diameter. Adjustment of the outside center guide track is provided by a movable rear idler. The driving sprocket is at the front and the track is returned on four return rollers positioned at the extremities of the semi-elliptical springs.

The power unit is the Delahaye, straight 6-cylinder, water-cooled, gasoline engine rated at 80 h.p. It has a bore of 84 mm and a stroke of 107 mm. The transmission is mounted centrally to the right of the driver. It provides five forward speeds and one reverse, the fifth speed being direct. The steering unit is housed in a large steel casting which forms the front plate of the vehicle. The brakes of external contracting type are mounted on the differential unit and therefore operate in oil.

Pz. Kpfw. III (Fl. W. 41): Flamethrower Tank

Pz. Kpfw. III (Fl. W. 41): Flamethrower Tank

The flame-throwing tank, put into service in 1942, consists of the standard Pz. Kpfw. III tank equipped with a flame projector instead of the usual tank gun. A machine gun is mounted coaxially in the turret and another is ball mounted in the front plate of the hull. Its road performance will approximate that of the Pz. Kpfw. III tank.

The flame tube, which looks like an ordinary cannon, contains 3 jets. The barrel behind the curved position of the armored shield is 134 cm long and at the flame end is 12 cm in diameter. Movement of the gun horizontally and vertically is controlled by two handwheels within reach of and to the left front of the tank commander. Propulsion of the liquid fuel for the flame thrower is achieved by means of a centrifugal pump driven by a small two-cylinder gasoline engine which is located in the engine compartment to the left of the tank motor. The fuel tanks are located beside the tank commander to the inside right and left side of the tank chassis.

Pz. Jäg. Lr. S. für 7.5 cm Pak 40/1 (Sd. Kfz. 135): S.P. Antitank Gun (on French Chassis)

Marder I: Pz. Jäg. Lr. S. für 7.5 cm Pak 40/1 (Sd. Kfz. 135): S.P. Antitank Gun (on French Chassis)

The French Lorraine tank chassis, in addition to being utilized as a self-propelled mount for the German 15 cm heavy field howitzer and the 15 cm heavy infantry gun, is also used for the high-velocity antitank gun, 7.5 cm Pak 40.

The Lorraine suspension arrangement consists of six small bogie wheels on each side, sprung in three pairs on three semi-elliptical springs. The driving sprocket is at the front, the track-adjusting idler at the rear, and four return rollers, located at the ends of the suspension springs, return the track, which is of the dry-pin type with outside center guides.

The power plant of this vehicle is the six-cylinder, in-line, water-cooled Delahaye engine rated at 70 hp. The ignition system is Bosch. Its main and reserve gasoline tanks hold 20 gallons and 5 1/2 gallons respectively.

The semi-automatic gun of monobloc construction is mounted within a high, open top, box-like shield, constructed of sloping 10 mm plate, well back on the chassis. The original gunshield overlaps the superstructure shield at the front. The gun is 134 inches in length and its muzzle with brake extends beyond the front of the chassis. The piece has the following muzzle velocities: H.E., 1800 f/s; A.P.C., 2525 f/s. Its appropriate elevation is -5° to +22°; traverse 65°. At 1000 yards, firing A.P.C. shell, it will defeat 3.6 inches of homogeneous armor at 30° obliquity, and 4.3 inches at normal.
