409: 339: 354:. The cannon had an overall length of 89 calibers (hence the additional designation L/89), which allowed 4,800 m (15,700 ft) maximum ceiling. The armour penetration was considerable when using dedicated ammunition, at 100 m distance it could penetrate 36 mm of a 60°-sloped armour, and at 800 m distance correspondingly 24 mm. It used a mechanical bolt for automatic fire, featuring a practical rate of fire of about 80 rounds per minute (rpm). The gun, when emplaced for combat, weighed 1,750 kg (3,860 lb), and complete for transport, including the wheeled mount, 3,560 kg (7,850 lb). 42: 549: 522: 468:(2,600 ft/s). This gave the Bofors an effective ceiling of about 4,900 m (16,100 ft) compared to 4,200 m (13,800 ft) for the Flak series. Firing rates for the earlier models were similar, although the Flak 43's improved rates beat the Bofors. The most notable difference is the size and weight of the two weapons; the Bofors weighed just under 2,000 kg (4,400 lb) and required a two-axle trailer, while the earlier Flak models weighed 1,550 kg (3,420 lb) on a single-axle mount, and the 636: 665: 694: 723: 578: 607: 362:
that cut the complete weight to 1,550 kg (3,420 lb) in combat and 2,400 kg (5,300 lb) in transport. The gun's ballistic characteristics were not changed, although the practical rate of fire was raised to 120 rpm (180 rpm theoretical). A new, simplified sighting system introduced
