Nicholas de Larrinaga reports for Janes 360 on the latest version of my favourite recoilless rifle:
Saab debuted a new variant of its Carl Gustaf 84 mm shoulder-fired recoilless rifle, the M4, during a series of demonstration firings at the Bofors Test Center at Karlskoga, Sweden, on 24 September.
The latest version of the nearly 70-year-old weapon system has been designed to offer significant weight savings over its predecessors, as well as improvements to other aspects of the system.
The M4 weighs 6.7 kg, some 3 kg lighter than the earlier Carl Gustaf M3 and half the weight of the 14.2 kg M2 version still in service with many nations. This has been achieved by constructing the recoilless rifle’s barrel out of titanium, saving 1.1 kg (compared to the M3’s steel barrel), building its outer casing our of carbon fibre (saving 0.8 kg), and by redesigning the weapon’s venturi to save a further 0.9 kg. The redesign has also served to decrease the size of the Carl Gustaf, bringing the M4’s total length down to under 1,000 mm.

There are currently 11 different ammunition types available for the Carl Gustaf weapon system, providing considerable operational flexibility. Programmable ‘smart’ ammunition types for use with the M4 are expected to be the next to reach the market. Saab officials also disclosed they are working on a new concept of ammunition for the Carl Gustaf: and ‘Ultra-Light Missile’ that would feature lock-on before launch guidance, feature several attack modes, and have a range of 1,500-2,000 m – approximately doubling the range of the existing Carl Gustaf ammunition types.
