Panzer 38(t)

The Panzerkampfwagen 38(t), originally known as the Českomoravská Kolben-Daněk (ČKD) LT vz. 38, was a tank designed during the 1930s, which saw extensive service during World War II. Developed in Czechoslovakia by ČKD, the type was adopted by Nazi Germany following the German occupation of Czechoslovakia. With the German Army and other Axis forces, the type saw service in the invasions of Poland, France and the USSR. Production ended in 1942, when its main armament was deemed inadequate. In all, over 1,400 Pz. 38(t)s were manufactured. The chassis of the Pz. 38(t) continued to be produced for the Marder III (1942–1944) with some of its components used in the later Hetzer tank destroyer and its derivative vehicles.

Description
The Panzer 38(t) was a conventional inter-war tank design, with riveted armour. The armour varied in thickness from 10 mm to 25 mm in most versions. Later models (Ausf. E on) increased this to 50 mm by bolting on an additional 25 mm armour plate to the front portion of the hull. The sides received an additional 15 mm increase of armour from Ausf. E production runs onward. The two-man turret was centrally located, and housed the tank's main armament, a 37 mm Skoda A7 gun with 90 rounds of ammunition. In addition, a 7.92 mm machine gun was in a ball mount to the right of the main gun. This machine gun could be trained on targets independently of the main gun, or coupled to the main gun for use as a conventional coaxial machine gun. The driver was in the front right of the hull, with the radio operator seated to the driver's left. The radio operator manned the hull-mounted 7.92 mm machine gun in front in addition to operating the radio on his left. The driver could also fire the hull machine gun with a trigger fitted on the left tiller bar. A total of 2,550 rounds were carried for the bow and turret machine guns. In German service, a loader position was added to the turret by reducing the ammunition capacity by 18 rounds. All future Panzer 38(t) tanks were rebuilt according to this specification and those already in service were modified accordingly. The commander had to aim and fire the main gun in addition to his role as commander. Minor adjustments, such as adjustable seats for the driver and firmer footing for the commander/gunner and loader, were also made. The engine was mounted in the rear of the hull and powered the tank through a transmission at the front of the hull with five forward gears and one reverse gear. The track ran under four rubber-tyred road wheels and back over a rear idler and two track return rollers. The wheels were mounted on a leaf-spring double-bogie mounted on two axles. == Development ==
Development
In 1935, the Czechoslovak tank manufacturer ČKD was looking for a replacement for the LT-35 tank they were jointly producing with Škoda Works. The LT-35 was complex and had shortcomings, and ČKD felt there would be orders both from the expanding Czechoslovak army and for export. ČKD decided to use a leaf-spring suspension with four large wheels for their new tank with an export success under the name "TNH". The main advantages of the Panzer 38(t), compared to other tanks of the day, were high reliability and sustained mobility. In one documented case, a regiment was supplied with tanks driven straight from the factory in 2.5 days instead of the anticipated week, without any mechanical breakdowns. In the opinion of the crews, the drive components of the Pz. 38(t) – engine, gear, steering, suspension, wheels and tracks – were perfectly in tune with each other. The Pz. 38(t) was also considered to be very easy to maintain and repair. After production of the Pz. 38(t) ceased, the chassis was used for tank destroyer designs, which were produced in greater numbers than the original Pz. 38(t). no changes were made to the 116 m/41 ordered from Scania-Vabis in June 1941. Deliveries started in December 1942 and were completed in August 1943, no less than three years behind the original plan. While clearly outdated, the need for a 10-ton light tank was so pressing that another order was placed in mid 1942. Since Scania-Vabis had reached the production ceiling, the 122 tanks had to be complemented by some 80 strv m/40. The second batch had the frontal armour upgraded to 50 mm bringing the weight to 11 tonnes, and to deal with the increased weight the 145 hp Scania-Vabis typ 1664 was replaced by a more powerful 160 hp Scania-Vabis typ 603. Due to the larger size, the hull had to be made 65 mm longer causing a wider gap between the second and third roadwheel. This enabled the fueltanks to be upgraded from 190 litres to 230 litres. Only 104 got delivered when production ended in March 1944; the last 18 chassis were built as the assault gun Stormartillerivagn m/43 instead. Another 18 Sav m/43 were purpose built. At the end of the 1950s, 220 SI & SII were converted to Pansarbandvagn 301 armoured personnel carriers and the turrets used for airbase defences. == Operational history ==
Operational history
Germany in 1939 The Panzer 38(t) performed well in the invasion of Poland in 1939 and the Battle of France in 1940. It was also used in the German invasion of the Soviet Union from 1941 onwards in German and Hungarian units but, like other Axis tanks, was outclassed by Soviet tanks such as the T-34. • Slovak National Uprising: 13 tanks of this type were used by the Slovak insurgent army. Iran Iran purchased 50 TNH tanks armed with a Skoda 37mm gun. A further order of 200 was interrupted by the German occupation of Czechoslovakia. Iranian TNHs were assigned to the 1st and 2nd Divisions and the Imperial Guards but were overwhelmed by the 1000 tanks used by the Soviet Army in the Anglo-Soviet invasion in August 1941. Peru A Peruvian mission went to Europe in 1935 and looked at tanks from several major manufacturers before settling on the Czech LTP. Peru bought 24 of them. They were delivered in 1938–1939 and designated 38 (then 39). This small armoured force of two tank companies was complemented by truck-mounted infantry and artillery pulled by tractors (the Czech ČKD). Peruvian doctrine was influenced by the French military mission operating in Peru at the time, and emphasized the use of tanks to support infantry attacks rather than in independent mobile columns (as in the German Blitzkrieg). The Peruvian tank battalion played an important role in the 1941 Ecuadorian–Peruvian War, spearheading the attack across the Zarumilla River and at Arenillas. Hungary With a local designation T-38 was used by the Royal Hungarian army. 108 were handed over between 1941 and 1942. 92 deployed with the 1.st Field Armoured Division. Romania The T-38 was the local designation for the wartime deliveries of Panzer 38(t)s from Germany in 1943. T-38 served with the forces operating in Kuban within 2nd Tank Regiment and later the 54th Company attached to the HQ and the cavalry corps in Kuban and Crimea. T-38 tanks were still in action with the 10th Infantry Division and Cavalry Divisions in 1944. Slovakia In the Slovak Army, this tank received the designation LT-38. Because of the first series of the LT-38 was not yet finished in March 1939, when Czechoslovakia dissolved, and as the first series was seized by Nazi Germany, the army of the Slovak State, which was a German ally in the Polish and Soviet campaigns, initially had only LT-35 tanks. In 1940 the Slovak Army ordered 10 tanks, which were used in Operation Barbarossa. All of them were used at the Eastern Front in the Fast division in the Battalion of Assault Vehicles. Two tanks were destroyed; the other 8 tanks later returned to Slovakia. After that, the Slovak Army ordered another 27 tanks, and when the Germans started withdrawing Panzer 38(t) tanks, the Slovak Army received another 37 tanks from Germany. Thirteen tanks of this type were used by Slovak insurgents during the Slovak National Uprising in 1944. One complete LT-38 tank in Slovak camouflage and one LT-38 torso are displayed in the Museum of the Slovak National Uprising in Banská Bystrica. Tank 313, the torso of which can be seen in the museum, was the third tank of the first order and saw combat on the Eastern front. Later it was used for training because of its high mileage. During the Slovak National Uprising it was used by insurgents, but because its engine failed, it was abandoned. Sweden All Strv m/41 SI were sent to P 3 in Strängnäs, who were the only regiment who painted the road-wheels in the same camouflage pattern as the hull against regulations prescribing field-grey to be used. Most of the m/41 SII went to P 4 in Skövde, with a small number allocated to P 2 in Hässleholm and the material reserve of P 3. All tanks had been retired from active service in the mid-1950s and later rebuilt into Pansarbandvagn 301 armoured personnel carriers (APCs). == Technical data ==
