Pz. Kpfw. V: Heavy Tank—Experimental

Neubaufahrzeug

Although this tank represents a great deal of Germany’s early experimental development, it is reported that only three were produced (1937), and that two were seen in Norway (1941) where they were destroyed, while the third was destroyed by the Russians near the Rumanian border.

The Pz. Kpfw. V, weighing 36 tons equipped for action, was manned by a crew of seven—commander, driver, main gunner, loader, wireless operator/machine gunner, and two auxiliary turret machine gunners. In addition to the main turret which mounted a 7.5 cm Kw. K. and coaxial 3.7 cm gun and machine gun, there were two additional revolving machine-gun turrets fitted in the front right and rear left of the hull, each fitted with a 7.9 mm machine gun.

Its suspension consisted of ten small bogie wheels mounted in articulating pairs, and four return rollers. Between the high front idler and first bogie assembly an additional independent roller resisted the track. The driving sprocket, unlike usual German procedure, is mounted in the rear, as is the engine, a V-12 HL 120 TRM, and the transmission and differential assemblies.

The sloping turret and the circular superstructure employed considerable riveted as well as welded construction. The commander’s cupola, fitted with periscope, was situated at the rear of the turret. Access doors were located on each side of the turret. Riveted armor skirting was fitted along the length of the tank between bogie wheels and return rollers. Two access doors were located in the forward portion of the skirting on the right side and one on the left.

This was considered a heavily armed vehicle, but it in no way represented German design technique for that period but rather that of several years previous.

s. Zgkw. 18t (Sd. Kfz. 9): Heavy Semitrack Prime Mover

s. Zgkw. 18t - Sd.Kfz. 9: Heavy Semitrack Prime Mover

This 18-ton vehicle is the heaviest of the German semitrack prime movers. It is often used by the Germans in the evacuation of their damaged tanks. It has a net weight of 16.8 tons and a combat weight of 19.8 tons. Its personnel capacity is 8, including driver and helper, and it can tow a trailer load of 20 tons. The maximum highway range of action is 160 miles on a fuel tank capacity of 72 gallons. Its weight distribution is as follows: front wheels, 5,289 pounds; track, 34,320 pounds.

The front suspension is comprised of a tubular floating axle mounting two pneumatic-tired, heavy duty wheels with transverse leaf springing. The track suspension is the standard semitrack system consisting of straddle-mounted rubber-tired bogie wheels sprung on torsion bars housed in cross tubes; front sprocket, rear idler, and needle-bearing track.

The power plant is the V-12 cylinder, Maybach gasoline engine rated at 230 horsepower. The transmission provides four speeds forward and one reverse with high and low range. Steering is effected by normal steering wheel and an epicyclic-controlled differential drive for the track with a brake linkage connected to the front-wheel steering system.

In addition to the electric starter, this vehicle is also equipped with a Bosch airplane-type inertia starter located on the right side of the engine.

A power winch is located at the rear, with facilities for passing the cable beneath the vehicle and out the front end. The winch-driving mechanism and the drum are located near the center of the chassis. The drum is horizontal and is driven by a propeller shaft from the rear of the transmission. The hub of the winch-driving mechanism is fitted with a slide gear which enables the operator to engage and disengage the winch from the rear of the vehicle. The winch-lifting capacity is 7.7 tons.

s. Krad: Heavy Motorcycle with Sidecar

WW2 Motorcycle - s. Krad, Heavy Motorcycle with Sidecar

The motorcycle, due primarily to its economy of operation, has received extensive development in Germany. The following manufacturing types are known to exist: Ardie, B.M.W., D.K.W., Horex, U.S.U., Phänomen, Puch, Standard, Tornax, Triumph, Victoria, Zundapp, and C.S. (Czech). The vehicle described herein is the B.M.W. Its outstanding operational features are: (1) a shaft final drive instead of a chain drive; (2) sidecar wheel-drive arrangement; (3) high and low range transmission, and (4) hydraulic brakes. Its average road speed is 55 m.p.h.; maximum speed, 75 m.p.h.

The frame and fork are made of pressed steel. The wheels are spoked and have dismountable axles in front and rear. The front, rear, sidecar, and spare wheels are all interchangeable.

The vehicle is powered by a 2-cylinder, air-cooled engine rated 25.4 horsepower at 3900 r.p.m. It weighs 192 pounds, has a bore of 3.07 inches, and a displacement of 45.5 cubic inches. The ignition system is the Noris type ZG 2A with automatic spark control. Full-pressure lubrication is provided. The capacity of the gasoline tank is 6 1/3 gallons.

The power train includes the single dry disk clutch, the synchromesh transmission of four speeds forward and one reverse with high and low range, and the final shaft drive with bevel gear reduction of 5.69. In order to make the cycle and sidecar combination more capable of cross-country operation, the sidecar also drives. As the drive comes back from the transmission, it enters the rear gear case by means of a shaft mounted parallel to the direction of motion. The rear wheel of the cycle is driven by means of a ring and pinion gear. However, the wheel is not on the same center as the ring gear, a pair of spur gears being mounted between the ring and the wheel to afford a further gear reduction. This gives the wheel an offset of about 4 inches to the rear of the ring gear. From the right of the ring gear the drive passes through a differential to the sidecar wheel.

The rear and sidecar wheels have hydraulic brakes; the front wheel mechanical brakes.

8 cm s. Gr. W. 34: Heavy Mortar

8 cm s. Gr. W. 34: Heavy Mortar (WW2)

The German 8.1 cm heavy mortar, first manufactured in 1934, is of conventional design, consisting of a tube, base cap, and firing-pin mechanism. Wall thickness of the tube or barrel tapers from 0.288 inch at the base cap to 0.190 inch; a collar at the muzzle slightly increases the wall thickness at that point. A leather-covered handle attached to the collar clamp near the muzzle is used apparently to change elevations when the tube is hot. The firing pin mechanism can be adjusted for two positions. In the “On” position, the pin protrudes into the tube the correct length for firing; in the “Safe” position, the firing-pin head is retracted, permitting greater safety in unloading the mortar in the event of a misfire or other malfunction. The change in setting is readily made by means of an adjuster located on the side of the base ring. The mortar is supported by a bipod and base plate.

The bipod includes cross-leveling, elevating and traversing mechanisms. The legs, and all other nonsliding parts, are made of light white metal. These legs, which have spikes and feet attached to the bottom, are adjusted to any one of six positions by a lever and held in place by locking gears. General construction of the bipod is sturdy and compact. It is easily folded for carrying purposes by swinging the cradle, which is hinged on the traversing mechanism sliding housing, until the left hook at the rear of the cradle is mated in the slot at the top of the rear bipod connector plate. The cradle is then traversed to the left, locking the hooks into the connector plate, and the legs are brought together.

The sighting system, having a total weight of 2 1/2 pounds, includes a collimator, cross level, longitudinal level, and an elevating and lateral deflection mechanism. Machining of the sight parts is excellent, and when in use it is attached to a mount on the left side of the traversing mechanism mount.

8.8 cm Pak 43/41: Antitank Gun

8.8 cm Pak 43/41: Antitank Gun

The Pak 43, one of Germany’s newer antitank guns, is a more solidly built weapon than the 7.5 cm Pak 40. The gun is mounted on large rubber-tired metal wheels. A sloping double shield, 6 feet, 3 inches in height, is fitted to the carriage for the protection of the gun crew. Split trails, approximately 12 feet long, are also supplied.

A muzzle brake is fitted to the barrel. The semi-automatic breech mechanism of the horizontal sliding block type is operated by a small auxiliary cylinder on the left side of the breechblock.

The buffer and recuperator are contained in one cylinder which is fitted above the barrel; the balancing cylinders are mounted vertically on either side of the carriage.

The sight bracket is marked for 8.8 cm Pak 43/41 and 8.8 cm Pak 43 Sfl. This marking tends to confirm the opinion that the Pak 43 is a modification of, or development from, the 8.8 cm Flak 41, which it resembles superficially. This marking also confirms the information that this gun, with the designation 43/1, is used in the self-propelled piece Pz. Jag. III/IV (the “Hornet”).

m. gp. Mannsch. Kw. (Sd. Kfz. 251): Medium Armored Personnel Carrier

m. gp. Mannsch. Kw. (Sd. Kfz. 251): Medium Armored Personnel Carrier

This vehicle is a medium armored personnel carrier with the chassis of the Sd. Kfz. 11 (light semitracked prime mover). The Sd. Kfz. 11 has been modified by placing armor on the chassis, altering the cooling arrangement, and mounting the steering wheel in an inverted position. The armor plate thickness measures 7.5 mm on the radiator cover, 8.5 mm on the sides, and 15 mm on the lower front plate, set at angles to the horizontal of 81°, 55-60°, and 55° respectively. It has been reported that these vehicles were used by the motorized infantry of armored divisions. Eight variations are known to exist with designations 251/1 through 251/8. The vehicles are used for infantry, ammunition and as command vehicles with built-in wireless, or ambulances.

The suspension is the same as that utilized for the Sd. Kfz. 11, as is also the power plant and the power train.

The armament normally consists of two 7.92 mm M.G. 34’s, one on a mount welded to the front of the chassis and one on an antiaircraft pedestal mount in the rear of the vehicle. Reports have been received that the 2 cm Kw.K. 30 is also mounted. The vehicle has a seating capacity for eleven men, including the driver.

l. gp. Mannsch. Kw. (Sd. Kfz. 250): Light Armored Personnel Carrier

l. gp. Mannsch. Kw. (Sd. Kfz. 250): Light Armored Personnel Carrier

This is a light armored personnel carrier with the chassis of a 1-ton light semitrack. It is often used by antitank units and, towing a small trailer, by infantry units in motorized formations. The front of the chassis, with its pneumatic tires mounted on disk-type wheels, and the forward superstructure are similar to that of the ordinary motor car. The riding compartment at the rear is built low and has a seating capacity for six men including the driver. Four vision ports are provided, two in the front plate of the driving compartment and one at each side thereof. The thickness of the superstructure plate averages from 10 to 15 mm.

The vehicle is powered by a Maybach, 6-cylinder, water-cooled engine rated 100 horsepower. The transmission, of the semiautomatic preselective type, provides seven forward speeds and three reverse. The drive is taken to the final drive sprockets from the spiral beveled gear on the forward end of the lower gearbox shaft, through a gear train and a differential unit of the spur gear and pinion type. The steering brakes, utilized for turns over 15° are built into the gear train and act on the epicyclic reduction units.

The flexible track suspension consists of front sprocket and rear idler and four pairs of rubber-tired bogie wheels on each side. The front of the vehicle is mounted on two single pneumatic-tired wheels, fitted on an axle suspended by a single transverse semi-elliptic spring.

Armament for this vehicle is a machine gun mounted within a shield at the forward end of the riding compartment.

s. Pz. Sp. Wg. (Sd. Kfz. 231, 232, 263): 8-Wheeled Armored Cars

Panzerspahwagen

The “8 Rad Panzerspahwagen” is the standard heavy armored car now in use by the Germans. It is a highly mobile, cross-country vehicle used by reconnaissance units. The car is armed with one 20 mm automatic cannon and one 7.92 mm machine gun, coaxially mounted in the turret. A 9 mm M.P. 38 or 40 is also carried. It is also equipped with periscope attachments for the camera used on scouting missions.

This vehicle is unusual in that all eight wheels are powered, and a steering control system at each end enables the crew to operate it from either end quite efficiently. The rear end control can be engaged or disengaged, whereas the front end control is permanently engaged.

The wheel suspension is very flexible. It consists of four longitudinal semi-elliptic springs, two on each side of the frame. Each spring is secured to the vehicle frame at its center on a fiber bearing to permit easy maneuvering over rough terrain.

The engine is a water-cooled, V-8, gasoline type of approximately 155 horsepower. The transmission has six speeds that can be used in either direction.

There are several variations of this car: one with radio and antenna and another without; one with a rotating turret; one with a fixed turret; and a turretless type mounting the 75 mm short tank gun, Kw.K.

7.92 mm M.G. 15: Flexible Aircraft Machine Gun

7.92 mm M.G. 15: Flexible Aircraft Machine Gun

The M.G. 15, a reliable weapon, was the standard flexible aircraft machine gun in the German Air Force until it was replaced by the M.G. 81, because the latter is more easily manufactured. It is still used in some aircraft, however, and has been recently modified by the addition of a bipod and ground sights for use as a ground weapon for air force troops. Its efficiency as a ground gun is questionable because of the difficulty of changing barrels.

It is a recoil-operated, gas-assisted, drum-fed, air-cooled, automatic gun. The M.G. 15 has a Solothurn-type action, except that the locking arrangement is placed on the rear of the bolt instead of on the bolthead as in other German Solothurn-type guns. It was the first Nazi weapon to be fed by a saddle-type drum.

The Japanese have painstakingly copied it, even to the ammunition, and call their version the Model 98 (1938) 7.92 mm Aircraft Flexible Gun.

9 mm M.P. 34/1 (Bergmann): Submachine Gun

9 mm M.P. 34 Bergmann Submachine Gun

The Bergmann 9 mm machine pistol, M.P. 341, is a semi- or full-automatic, air-cooled, blow-back-operated submachine gun which is fed by a box magazine containing 32 rounds. It is manufactured commercially in Germany for use by the German Army. It is also used by other countries in modified forms. This is only one of several types of submachine guns.

The barrel and moving parts are, except for the trigger mechanism, housed in a long cylindrical tube. The forward end of this tube is perforated and forms a cooling jacket for the barrel; the rear portion serves as a receiver or housing for the bolt group. The M.P. 341, unlike the M.P. 181, is cocked by a turning bolt handle, and has a positive safety mechanism.
