German armored forces in World War II created a variety of vehicles by mounting anti-tank guns on obsolete tank chassis. These machines performed even better than expected, yet were still vulnerable due to high vehicle profiles and open-topped turrets. Allied bombings took a heavy toll on German production facilities, and further increased the need for an easily produced yet effective light tank destroyer to replace vehicles like the StuG III and Marder series. Prototypes of the Jagdpanzer 38 were ready by 1944 and mass production began in April of that year. The Jagdpanzer 38 was covered entirely with sloped armor, and possessed a compact form and low silhouette, giving it much improved defensive ability over other self-propelled guns. Armament consisted of a 7.5 cm Pak 39 L/48 gun in fixed mounting as well as a remote-controlled MG 34. It featured a wide body to accommodate the four-man crew, as well as strengthened lower hull with enlarged wheels, guide rollers and tracks.

Jagdpanzer 38s first entered service in July 1944, and would eventually be assigned to a number of units, including infantry, Panzerjäger and Volksgrenadier divisions. BMM and Škoda continually modified and improved the Jagdpanzer 38 during production of the more than 2,800 vehicles built. Owing to the ease of production and high operating rates, the Jagdpanzer 38 came to serve as Germany's main tank destroyer in the latter period of the war, making an important contribution on both the Eastern and Western Fronts.

Name

The name Hetzer (German for "baiter" or "chaser") was at the time not used for this vehicle. It was the designation for a related prototype, the E-10. The Škoda factory for a very short period confused the two names in its documentation and the very first unit equipped with the vehicle thus for a few weeks applied the incorrect name until matters were clarified. However, there exists a briefing paper from Heinz Guderian to Hitler saying that an unofficial name, Hetzer, had spontaneously been coined by the troops. Post-war historians basing themselves on this statement made the name popular in their works, though the vehicle was never named as such in official documents.[3]

Development

The Jagdpanzer 38 was intended to be more cost-effective than the much more ambitious Jagdpanther and Jagdtiger designs of the same period. Using a proven chassis, it avoided the mechanical problems of the larger armoured vehicles.

British historian Mark Axworthy suggests that the design for the Hetzer was likely rooted from the Romanian "Mareşal" tank destroyer. In November–December 1943, a Romanian commission ordered from Germany and German-occupied France several components which could not be made in Romania, and this drew German attention to the Mareşal. Hitler had approved the development of the Hetzer on 7 December 1943. That same month, Marshal Antonescu (Conducător of Romania at the time) commended the Mareşal project to Hitler. Soon afterwards, on 6 January 1944, Hitler was presented with the plans of the Mareşal M-04 prototype. Axworthy notes that the Hetzer's armament, armor configuration and chassis broadening were very similar to those of the M-04. He also reports that in May 1944, German Lieutenant-Colonel Ventz (a delegate of the Waffenamt) admitted that the Hetzer had followed the Romanian design solution.[4] American historian Steven Zaloga writes that "The Germans were impressed with the overall layout of the Mareşal, and it is credited with being the inspiration for the German Jagdpanzer 38(t) tank destroyer."[5]

It was built on the Panzerkampfwagen 38(t)'s widened and lengthened chassis with modified suspension (larger road-wheels from the Praga TNH n.A prototype reconnaissance tank) and up-rated engine. The new engine was 160 PS Praga AC/2 6-cylinder engine coupled to a Praga-Wilson gearbox (5 forward and 1 reverse gear). The chassis was modified in order to accommodate a larger gun and thicker armour than the regular Panzerkampfwagen 38(t) tank. Its combat weight was 16 metric tons (versus 9.8-tonnes for the Pz 38(t)) and it could travel at a maximum speed of 42 km/h.

It was better armored than the thinly armoured earlier Panzerjäger Marder III and Nashorn with a sloped armour front plate of 60 mm sloped back at 60 degrees from the vertical (equivalent in protection to about 120 mm), carried a reasonably powerful 75 mm gun, was mechanically reliable, small and easily concealed. It was also cheap to build.

The Jagdpanzer 38 succeeded the open-top Marder III (based on the same chassis). Starting from April 1944, about 2584 were built until the end of the war. The older Marder III Panzerjäger series retained the same vertically sided chassis as Panzer 38(t). In the Jagdpanzer 38, the lower hull sides slope 15 degrees outward to make a roughly hexagonal shape when viewed from front or rear. This increased the available interior space and enabled a fully enclosed casemate-style fighting compartment. Because of the fully enclosed armor, it was 5 tonnes heavier than the Marder III. To compensate for the increased weight, track width was increased from 293 mm to 350 mm.[6]

Initial production Jagdpanzer 38 did not sit even with the ground because the gun, transmission and thicker frontal armor weighed the front down. The leaf springs were strengthened from June 1944, which leveled the posture of the vehicle. From May–July 1944, accessibility was improved in the form of more hatches: the commander's smaller hatch opening to the rear, one in the right rear corner for radiator access, and one in the left rear corner for fuel tank access. From August 1944, lighter inner and outer mantles reduced the weight by 200 kg. These were more conical looking compared with the half cone shaped initial mantles. Also from August 1944, new rear idler wheels were introduced that had 8, 6, and 4 (not necessarily in that order) lightening holes instead of 12. These simplified the manufacturing process. In September 1944, the front 16 spring leaves were increased in thickness to 9mm per leaf (the rear 16 remained 7mm thick). Also in September, the side Schürzen's front and rear tips were bent inward to prevent them from catching bushes and being torn off. It was discovered that the driver's periscope housing acted as a shot trap, preventing incoming shells from bouncing off the front glacis. The protruding housing was removed, instead the periscope was inserted into vertical cuts to the front armor from October 1944. Also from October 44, a flame reducing muffler was introduced, which reduced visibility and backfiring. A head cushion was added to the commander's hatch from October 1944. At the same time, road wheels' rims were riveted instead of bolted. To cope with the heavy front, and the necessity to traverse the vehicle to aim, the gear ratio was lowered from 1:7.33 to 1:8 to reduce the stress on final gears from January 1945. A buttoned-down Jagdpanzer 38 was blind to its right side. Since 20mm side armor (same as late model Panzer II's side armor) was adequate to protect the crew only from fairly small caliber guns, it was important to face the threat frontally. Hence, the commander's field of view was planned to be improved by installing a rotating periscope in the Jagdpanzer 38 Starr, just as the Sturmgeschutz III and Elefant had evolved from a single pair of periscopes to all around vision blocks. However, the Jagdpanzer 38 Starr came too late to see the action in the field.

Swiss Army G-13

The Jagdpanzer 38 equipped the Panzerjägerabteilungen (tank destroyer battalions) of the infantry divisions, giving them some limited mobile anti-armor capability. After the war, Czechoslovakia continued to build the type (versions ST-I and ST-III for training version, about 180 units built) and exported 158 vehicles (version G-13) to Switzerland. Most vehicles in today's collections are of Swiss origin.

By order of Adolf Hitler in November 1944, a number of Jagdpanzer 38s were refurbished straight from the factory with a Koebe flamethrower and accompanying equipment instead of the normal gun. The flame projector, encased in a metal shield reminiscent of that of a gun barrel, was very prone to damage. Fewer than 50 of these vehicles, designated Flammpanzer 38, were completed before the end of the war, but they were used operationally against Allied forces on the Western Front.

Further variants were a Jagdpanzer 38 carrying the 150 mm sIG 33/2 Howitzer, of which 30 were produced before the end of the war, and the Bergepanzer 38, a light recovery vehicle of which 170 were produced. Plans were made to produce other variants, including an assault gun version of the Jagdpanzer 38 carrying a 105 mm StuH 42 main cannon, a version mounting the 7.5 cm KwK 42 L/70 gun from the Panther, and an anti-aircraft variant mounted with a Flak turret. The war ended before these proposed models were put into production. Prototypes were also developed for the Jagdpanzer 38 Starr, this was a simplified version of the Jagdpanzer 38 and also a step towards the E-10. The design removed the recoil absorber from the main 7.5 cm Pak 39 gun, instead attaching the gun to the chassis, and using the Jagdpanzer 38's bulk and suspension to absorb the recoil. Three prototypes were built as were eleven pre-production vehicles, of which one was fitted with a diesel engine. Hitler ordered the one prototype committed to combat to be destroyed rather than let it be captured on 31 March 1945. The army requested on 29 April that the gun sights and traversing gear from the nine pre-production vehicles at the Milowitz proving ground, which it deemed not combat worthy, be removed and sent back to the factory to allow combat-ready vehicles to be completed.[7]

Variants
Jagdpanzer 38, exhibited in the Texas Military Forces Museum in Austin, USA.
  • Befehlswagen 38 - Command variant. Fitted with a 30W FuG 8 radio set.[8][6]
  • Flammpanzer 38 - Jagdpanzer 38 modified with a Koebe flamethrower in place of the main gun. Deployed on the Western Front, with first use during the Battle of the Bulge (20 in 352nd and 353rd Panzer-Flamm-Kompanies attached to Army Group G). Less than 50 units produced.[6]
  • Panzerjaeger 38(t) mit 75mm L/70 - Prototype version experimenting with mounting the 7.5cm KwK 42 L/70 gun from the Panther. 3 prototypes built, but the long gun and extra weight caused even bigger problems driving the vehicles. A proposal by Krupp to modify the Jagdpanzer 38 with a superstructure to the rear to mount the gun, but no more development was done on this idea.[6]
  • Jagdpanzer 38 Starr - A simplified version of the Jagdpanzer 38, which attached the 7.5cm Pak 39 gun to the chassis, fitted with a Tatra diesel engine. 10 were built, 9 converted back to normal Jagdpanzer 38. The remaining prototype was destroyed at the end of the war.[9][6]
  • Panzerjaeger 38(t) mit 105mm StuH 42/2 L/28 - A proposed version of the Jagdpanzer 38 Starr armed with a 10.5 cm howitzer.[6]
  • ST-I - Post-war Czech designation for new manufactured or repaired Jagdpanzer 38. 249 in service, together with 50 ST-III/CVP driver training vehicles (Unarmed chassis, some with a superstructure). Prototype developments included the Praga VT-III armoured recovery vehicle and PM-I flamethrower tank.[6]

The Jagdpanzer 38 fit into the lighter category of German tank destroyers that began with the Panzerjäger I, continued with the Marder series and ended with the Jagdpanzer 38. The 75 mm Pak 39 L/48 gun of the Jagdpanzer 38 was a modified version of the 75 mm StuK 40 L/48 used in the StuG III and StuG IV assault guns. With this gun the Jagdpanzer 38 was able to destroy nearly all Allied or Soviet tank types in service at long ranges (except heavy tanks) and its fully enclosed armor protection made it a safer vehicle to crew than the open-topped Marder II or Marder III series.

The vehicle could carry two different armor piercing shells for the Pak 39 gun: the Pzgr. 40 high-velocity tungsten cored round, which fired a 4.1 kg (9.0 lb) projectile at 930 m/s that could penetrate 120 mm of armor at 500 meters and 97 mm at 1,000 meters striking at a 30-degree angle, but was often in scarce supply; and the Pzgr. 39 armor piercing, ballistic-capped with explosive filler and tracer element, launching a heavier 6.8 kg (15 lb) projectile at 750 m/s that could pierce 106 mm (4.2 in) of armor at 500 meters and 95 mm at 1,000 meters. Based on tests using Pzgr. 39 ammunition, with correct range estimation and competent gunnery a 99% chance of a first-shot hit at 500 m and a 71% chance at 1,000 m was estimated. The vehicle also carried standard high-explosive rounds and the Gr. 38 HL/C HEAT round designed with a shaped charge, but this was less effective and accurate against armored targets than AP rounds.[13]

The Jagdpanzer 38 was one of the most common late-war German tank destroyers. It was available in relatively large numbers and was generally mechanically reliable.[14] Like some other late-war German SPGs, the Jagdpanzer 38 mounted a remote-control machine gun mount, which could be fired from within the vehicle. This proved popular with crews, though to reload the gun a crewmember needed to expose himself to enemy fire.

The vehicle's small size made it easier to conceal than larger vehicles. A self-propelled gun such as this was not intended for a mobile, meeting engagement or the typical Wehrmacht blitzkrieg style of warfare. Instead, a light self-propelled gun like the Jagdpanzer 38 excelled when emplaced along pre-determined lines of sight where the enemy was expected to approach and when used in defensive positions to support a prepared ambush. The Jagdpanzer 38 is similar in its dimensions and vertical profile to the minuscule and undergunned Panzer II, a prewar tank. However, by 1944, the majority of tanks were much larger and heavier; a Jagdpanzer 38 waiting motionless in an ambush position was a much smaller target to detect and hit than many other armoured fighting vehicles of the time. Its main failings were comparatively thin side armor, limited ammunition storage, poor gun traverse, poor internal layout that made operating the vehicle difficult, as well as leaf springs and drive wheels that were prone to failure due to the increased weight.[15] Using the Jagdpanzer 38 and similar vehicles according to a defensive doctrine would offset some of the disadvantages of poor side armor and limited gun traverse.

Operational history

The Jagdpanzer 38 first entered service with the Heeres Panzerjäger-Abteilung 731 in July 1944. This unit was sent to Army Group North on the Eastern Front.[16] One report from the Eastern Front described that a company of Jagdpanzer 38 destroyed 20 enemy tanks without any losses.[17]

Survivors

Due to the large number produced, the Jagdpanzer 38 is probably the most abundant World War II German tank destroyer remaining today, though many survivors are actually post-war Swiss G-13 variants. In addition to numerous examples in museums, there are Jagdpanzer 38 in various conditions in private collections.

In 2007, a Jagdpanzer 38 was recovered from the Baltic Sea in Jurata, Poland. It is currently being restored in Gdansk.[18]
