The Lahti L-39 is a Finnish 20 mm anti-tank rifle used during the Second World War. It had excellent accuracy, penetration and range, but its size made transportation difficult. It was nicknamed "Norsupyssy" ("Elephant Gun"), and as tanks developed armour too thick for the Lahti to penetrate its uses switched to long range sniping, tank harassment and with the L-39/44 fully automatic variant, an improvised anti-aircraft weapon.
Aimo Lahti had doubts about the original idea of a 13 mm anti-tank machine gun and started working on a 20 mm design. Officers who wanted smaller calibre anti-tank weapons believed that the muzzle velocity of 20 mm shells was insufficient to penetrate armour and a weapon with a higher rate of fire and in a smaller calibre would prove useful. As a result, Lahti designed two competing anti-tank weapons: a 13.2 mm machine gun and a 20 mm rifle. After test firing both weapons in 1939, they found that the 20 mm rifle displayed better penetration.
Lahti (Finnish pronunciation: [ˈlɑxti], Swedish: Lahtis) is a city and municipality in Finland.
Lahti is the capital of the Päijänne Tavastia region. It is situated on a bay at the southern end of lake Vesijärvi about 100 kilometres (60 mi) north-east of the capital Helsinki. In English, the Finnish word Lahti literally means bay. The Lahti region is growing and is one of the main economic hubs of Finland.
The coat of arms of the city depicts a train wheel surrounded by flames.
Lahti was first mentioned in documents in 1445. The village belonged to the parish of Hollola and was located at the medieval trade route of Ylinen Viipurintie, which linked the towns of Hämeenlinna and Vyborg.
The completion of the Riihimäki – St. Petersburg railway line in 1870 and the Vesijärvi canal in 1871 turned Lahti into a lively station, and industrial installations began to spring up around it. For a long time, the railway station at Vesijärvi Harbour was the second busiest station in Finland. Craftsmen, merchants, a few civil servants and a lot of industrial workers soon mixed in with the existing agricultural peasantry.
