Gw. Lr. S. für 15 cm s.F.H. 13: S.P. Heavy Field Howitzer (on French Lorraine Chassis)

Gw. Lr. S. für 15 cm s.F.H. 13: S.P. Heavy Field Howitzer (on French Lorraine Chassis)

This mobile artillery equipment consists of a French Lorraine chassis, “Tracteur Blinde 38 L,” on which is mounted the 15 cm. s.F.H. 13, a medium howitzer designed for the last war. The chassis type was produced shortly prior to this war as an armored ammunition and personnel carrier.

The chassis is divided into the driving compartment at the front, the engine compartment in the center and an open welled tray at the rear. The piece is mounted on the superstructure at the front of the tray and extends forward over the engine and driving compartments. The gun crew is stationed in the tray and is protected by a 9 mm armored body which is open at the top. At the extreme rear of the hull is a hinged spade which may be lowered when the gun is fired. The original carrier is armored by plates, bolted together of the following thicknesses : Nose of hull, 12 mm; glacis plate, 8 mm; front sloping plate, 9.5 mm; sides, 9 mm; back, 9 mm; top, 6 mm; floor, 5 mm. Except for a band about 12 inches high around the rear half of the sides and the rear of the vehicle there is no overlap in the two armors.

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 Delahaye 6-cylinder, in line, water-cooled, gasoline engine generates 80 horsepower. The ignition system is Bosch. The transmission provides 5 forward speeds and one reverse.

The piece has a muzzle velocity of 1250 f.s., bore length of 17 calibers, and a maximum range of 9300 yards. Its traverse as mounted is approximately 4 degrees and its elevation -5 to +45 degrees. It utilizes the following ammunition: H.E. shell, 92.4 lb.—Anti-concrete shell, 95.7 lb.—Smoke shell, 85.8 lb.—H.E. shell (stream­lined), 84.7 lb.

Pz. Jäg. II Aus D, E für 7.62 cm Pak 36 (Sd. Kfz. 131): S.P. Antitank Gun (Russian)

Pz. Jäg. II Aus D, E für 7.62 cm Pak 36 (Sd. Kfz. 131): S.P. Antitank Gun (Russian)

The Pz. Kpfw. II chassis embodying the suspension on four large bogie wheels has been used as a self-propelled mount for the German modified Russian gun 7.62 cm Pak 36 (r) as well as the Pz. Kpfw. II models utilizing five bogie wheels. These equipments are used in an antitank capacity.

The turret and superstructure of the original tank has been removed and replaced by a high box-like superstructure shield of approximately 15 mm thickness, sloping about 75° to the horizontal. Centrally located above the lower shield superstructure is a three-sided shield of approximately 10 mm thickness with a slotted front plate through which the long muzzle of the gun projects well over the front of the chassis. The original shield of the gun has been retained.

The gun, 163 1/2 inches in length including the muzzle brake, is of monobloc construction. The breech mechanism is of the falling-wedge type. The elevating gear is operated by a handwheel located on the left side of the gun; the traversing gear is on the right. The estimated elevation of the piece is -5° to +22°; traverse 65°. Its muzzle velocities are as follows: H.E. shell, 1805 f/s; A.P.C. shell, 2430 f/s. Firing A.P.C. shell this gun will defeat 3.2 inches of homogeneous armor of 30° obliquity at 1000 yards, and 4.1 inches at normal.

Gw. II für 15 cm s.I.G. 33: S.P. Heavy Infantry Howitzer

Gw. II für 15 cm s.I.G. 33: S.P. Heavy Infantry Howitzer

This vehicle consists of the 15 cm. heavy infantry howitzer mounted in the hull of a modified, turretless Pz. Kpfw. II chassis. The chassis is approximately three feet longer than that of the standard Pz Kw II tank and has six bogie wheels instead of the usual five. The sprockets, rear idlers, bogie wheels, return rollers, steering assembly, gear box and hull nose are those of the Pz. Kpfw. II; the instrument panel is that of a Pz. Kpfw. III. The front shield is in one piece extending straight across the full width of the superstructure. The driver’s visor is of the double shutter type. The road performance of this equipment approximates that of the Pz. Kpfw. II tank.

The gun, a standard infantry support weapon, is mounted low in the hull, projecting through a vertical slot in the shield. The gun shield is 15 mm thick and is of shallow construction. It extends about a third of the distance of the superstructure to the rear. Unlike the “Wasp” there are no protecting side plates along the entire length of the superstructure.

The gun is 64.57 inches in length, has a muzzle velocity of 790 f.s. and a maximum effective range of 5140 yards. The casting containing the recuperator and buffer, housed underneath the barrel, extends almost to the end of the barrel. The breech mechanism is similar to the 10.5 cm. I.F.H. 18. The elevating qear is operated from the right and the traversing gear from the left. In field mounting its traverse is 11°, its elevation 0° to +73°.

Two types of ammunition are fired, the 15 cm. I. Gr. 33 and the 15 cm. I. Gr. 38. The H.E. capacity is high, 21.8%. The only other shell that the weapon is known to fire is a smoke shell, the 15 cm. I. Gr. 38 Nb. The same percussion fuze, s. I. Gr. Z. 23, which weighs 75 lbs., is used in each case.

Gw. für 15 cm s.I.G. 33/1 (Sd. Kfz. 138/1): S.P. Heavy Infantry Howitzer (on Czech Chassis)

Grille: Gw. für 15 cm s.I.G. 33/1 (Sd. Kfz. 138/1): S.P. Heavy Infantry Howitzer (on Czech Chassis)

The vehicle is the result of a combination of the 15 cm heavy infantry howitzer and the Pz. Kpfw. 38 (t) tank chassis. Its road performance will approximate that of the Pz. Kpfw. 38 (t) tank.

The howitzer, from which the trail has been removed, is mounted well forward on the chassis within a box-like, open top shield, the front plates of which overlap the original gun shield. The box shield has a thickness of 25 mm in front, 15 mm at the sides, and 15 mm at the rear. A further plate, fitted over the barrel and recuperator, is elevated and depressed with the howitzer, which also retains its original traversing and elevating mechanisms. Sighting is done through the aperture in the howitzer shield, by dial sight. Six metal sheets in the shape of a 3/4 circle are fitted to the sides of the fighting compartment, four vertically at the rear on the right, and two horizontally forward on the left. These may house a shell each, thus making a total of twelve rounds, corresponding to the 12 lockers for cartridge cases and charges. AW/T set is carried. This is mounted on the left wall of the fighting compartment. A folding type rod aerial is mounted on the left. The general appearance suggests that the equipment is overloaded. The silhouette is high.

The piece, a standard German infantry support weapon, has a length of 64.57 inches, a muzzle velocity of 790 f.s., and a maximum effective range of 5140 yards. Its field mounting traverse is reported as 11°, its elevation 0° to plus 73°. Its recoil mechanism, which consists of both buffer and recuperator, is housed in a casing underneath the barrel and extends almost the entire length of the latter. The gun fires an 83.6 lb. H.E. shell, and an 84.7 lb. smoke shell.

Gw. II (Wespe) für 10.5 cm le. F. H. 18/2 (Sd. Kfz. 124): S.P. Light Howitzer (Wasp)

Gw. II (Wespe) für 10.5 cm le. F. H. 18/2 (Sd. Kfz. 124): S.P. Light Howitzer (Wasp)

This equipment, known as the “Wasp,” consists of the 10.5 cm. light field howitzer mounted on a chassis which, with the exception that there are only three return rollers, is that of a normal Pz. Kpfw. II tank, Models A-C, with five bogie wheels. Its road performance approximates that of the Pz. Kpfw. II tank.

The gun is the 10.5 cm. 1.F.H. 18 M with muzzle brake. It is mounted at the rear of the chassis within an open top box type shield which is 10 mm thick, its muzzle brake being almost flush with the front of the chassis. Its recuperator and buffer mechanisms, mounted on the bottom and top of the barrel, respectively, are clearly visible beyond the shield. Overlapping the gun shield and sloping back to the rear of the superstructure are side plates, also 10 mm thick. The fighting compartment is open at the top and rear. Its silhouette is high.

The piece has a normal-charge muzzle velocity of 1542 f.s. and a maximum range of 11,650 yards. Firing the long range charge (Fern-ladung) the gun has a muzzle velocity of 1772 f.s. and a maximum range of 13,500 yards. All charges, except the long range, can be fired without the muzzle brake. It has a traverse of 32° and an elevation of -5° to +42°. It is reported to fire four types of ammunition, the 32.6 lb. HE (F. H. Gr.—Feldhaubitze Granate—field howitzer shell), the cast steel HE (F. H. Gr. Stg.—Stahlring—steelring), the 25.9 lb. hollow charge (10 cm. Gr. 39 rot Rohl Ladung—red hollow charge), and a 32.5 lb. smoke shell.

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°.

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.

Pz. Jäg. 38 für 7.62 cm Pak 36 (r) (Sd. Kfz. 139): S.P. Antitank Gun (on Czech Chassis)

Pz. Jäg. 38 für 7.62 cm Pak 36 (r) (Sd. Kfz. 139): S.P. Antitank Gun (on Czech Chassis): Marder III Panzerjäger

This vehicle is an ex-Czech light tank chassis mounting a Russian 7.62 cm Pak 36 (r). The mechanical layout and components are identical with those of the Pz. Kpfw. 38 (t) tank and its road performance will therefore be similar.

The conversion to a self-propelled mounting has been achieved by the removal of the turret and the superstructure top plate of the original tank. The turntable for the gun is mounted on the superstructure at four points on transverse and lateral beams. A three-sided shield of 10 mm plate is secured by bolting and welding to the original front gun shield, and by tubular supports to the mounting. This shield traverses with the gun. A sliding mantlet is provided in the shield to permit elevation and depression of the gun. A lower, fixed three-sided shield is bolted to the superstructure. This is of 15 mm plate. The sloping side covers have been replaced by flat hatches hinged to the sides.

The gun is of monobloc construction with detachable breech ring. It has an over-all length, including the double baffle muzzle brake and breech lock, of 163 1/2 ins. The elevating gear is driven from a handwheel, on a traverse axis, on the left of the gun. The traversing gear is hand operated from the right. The gun has the following muzzle velocities: HE shell, 1805 f.s; A.P.C. shell, 2430 f.s. The penetration performance firing A.P.C. shell against homogeneous armor is as follows: 500 yards 3.7 ins. at 30° obliquity, 1000 yards 3.2 ins. at 30°, 4.1 ins. normal—2000 yards 2.5 ins at 30°, 3.1 ins. normal—2500 yards 2.2 ins. at 30°, 2.8 ins. normal.

Additional armament on this vehicle consists of a 7.92 M.G. 37 (t) on a ball mounting in front superstructure; Discharger for 5 smoke generators, fired by cable from fighting compartment; 9 mm machine carbine.

Gw. III/IV (Hummel) für 15 cm s.F.H. 18/1 (Sd. Kfz. 165): S.P. Heavy Field Howitzer “Bumblebee”

Gw. III/IV (Hummel) für 15 cm s.F.H. 18/1 (Sd. Kfz. 165): S.P. Heavy Field Howitzer "Bumblebee"

This equipment, known as the “Bumble Bee,” is composed of the 15 cm heavy field howitzer mounted on a modified Pz. Kw. IV tank chassis. It should not be confused with the 10.5 cm l.F.H. 18/2 (“Wasp”), which is the 10.5 cm light field howitzer mounted on the chassis of a Pz. Kw. II tank. The road performance of the “Bee” will approximate that of the Pz. Kw. IV tank.

In the construction of this vehicle the following modifications were made to the hull of the Pz. Kw. IV tank. The turret top plate mounting the turret traversing ring, the front vertical plate, and the rear partition separating the engine from the fighting compartment have been removed. The engine, cooling-fan assembly and exhaust pipes have been moved forward up to the gear box. A partition has been built across the width of the hull dividing the driver and assistant driver from the fighting compartment. A steel plate separates the engine from the fighting compartment. In place of the driver’s entrance hatches a cover similar to a cupola, with lid and shutter type vision, is provided.

The superstructure is in the form of a sloping four-sided shield 10 mm (.39 inch) thick. The front of the shield provides a bulging slot for the traverse and elevation of the gun while the rear plate is fitted with a hinged door.

The gun is mounted well back on the top of the engine cover plate by means of angle iron and steel brackets so that its muzzle projects almost flush with the nose of the hull. It retains its original buffer, recuperator and compensator, and elevating and traversing gears. Its overall length including muzzle brake, with which it must be fitted when firing charge 8, is 17 feet, 4 1/4 inches. The muzzle velocities of this piece are: Charge 6, 1,020 f.s.; Charge 7, 1,375 f.s.; Charge 8, 1,965 f.s. The maximum ranges are: Charge 6, 10,550 yards; Charge 7, 12,140 yards; Charge 8, 14,380 yards. Its elevation is 0°-39°; traverse each side 16°.
