Saab has showcased its new programmable Carl-Gustaf munition, designated HE 448, during a live-fire demonstration in front of an audience in Karlskoga, Sweden on 3 and 4 May.
A new fire control device, designated FCD 558, was also demonstrated alongside the programmable high explosive round.
The HE 448 programmable round has the ability to communicate with the FCD 558 fire control device via a protocol named Firebolt.
The programmable Carl-Gustaf munition provides the fire control device with the exact information on the round type and propellant temperature and combines this with target distance to determine the best trajectory.
This means that Carl-Gustaf operators will be able to quickly configure a chambered round and so increase their operational effectiveness.
Michael Höglund, head of Saab’s business unit Ground Combat, said: ‘The FCD 558 also gives users a new option for equipping Carl-Gustaf with a more efficient sighting solution than the baseline configuration’.
This demonstration follows Saab’s award of the contract by the Swedish Armed Forces in December 2021.
According to Shephard Defence Insight, the Carl-Gustaf M4, the newest generation of the weapon system, has been ordered or procured by at least eight countries, Australia, Estonia, Latvia, Slovakia, Slovenia, Sweden and USA.
The most recent customer, Lithuania, announced in January 2022 that it had signed a framework agreement with Sweden for the platform.

Vehicle procurement in the Middle East continues to target big-ticket main battle tanks, with lighter platform purchases also potentially on the horizon including tactical, infantry fighting and armoured personnel carrier vehicles.
Positioned between light 4x4s and heavier 8x8 platforms, the new vehicle, Vantrex, aims to combine high payload capacity with IFV-level firepower in an increasingly competitive segment.
The latest infantry fighting vehicle from Rosoboronexport draws on experience from the war in Ukraine, and is designed to be more lethal and more survivable than its predecessors.
The Rhino 4x4 protected vehicle is being manufactured for an undisclosed country, likely to be Singapore, while its Agil counter-UAS C2 system is in low-rate production.
Saudi Arabia’s investment in its land forces, notably in the area of air defence as recently as 30 January, is a sign of the challenges the Gulf State faces, particularly the threat from Houthi rebels in Yemen.
