L40/70

The Bofors 40 mm L/70 is a towed anti-aircraft autocannon developed by Sweden's Bofors company, serving as an improved successor to the widely used L/60. It features a higher muzzle velocity and rate of fire, making it effective against faster-moving jet aircraft and also adaptable for ground support roles.

Developed in the late 1940s to counter the emerging threat of high-speed jet aircraft, the L/70 was designed to offer a significantly faster reaction time and greater effective range than previous air defense systems. It officially entered Swedish service in 1951 and was rapidly adopted as a standard light anti-aircraft weapon by numerous NATO and allied nations. The system saw extensive combat deployment in major 20th-century conflicts, including the Indo-Pakistani Wars and the Falklands War, where it was utilized by both British and Argentine forces. Today, the L/70 remains in active service globally, frequently modernized with advanced radar guidance, and has found renewed relevance as an effective countermeasure against unmanned aerial vehicles.
