were built in 1944. Swedish production Since the 90 PzKpfw 38(t) Ausf. S built for Sweden to be delivered in March 1940 were confiscated with the invasion of Czechoslovakia, negotiations with for the blue-prints needed for license production commenced and an agreement was reached at the end of 1940, which included the upgrades for the TNHP-S. The riveted construction was seen as a drawback, but since redrawing the blueprints for a welded construction was estimated to delay production by almost a year, 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 While clearly outdated, the need for a 10-ton light tank was so pressing that another order was placed in mid 1942.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 Germany The Panzer 38(t) performed well in the invasion of Poland in 1939 and the Battle of France in 1940. It was better armed than the Panzer I and Panzer II tanks. It was on a par with most light tank designs of the era, although it was unable to effectively engage the frontal armour of medium, heavy and infantry tank designs. 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. Some ex-German units were issued to the Romanians in 1943, after the loss
