Saab demonstrated the HEAT 758, a new 84mm anti-tank round for the Carl-Gustaf M4 recoilless rifle, during a live firing at Karlskoga, Sweden on May 7. The round is designed to defeat modern explosive reactive armor including Russia's Kontakt-1, Kontakt-5, and Relikt systems. Unlike conventional tandem-charge munitions, which use a precursor charge to detonate the reactive armor before the main warhead hits, the HEAT 758 uses what Saab calls a Non-Initiating Precursor. It strikes hard enough to physically penetrate the ERA cassette and open a path for the shaped charge jet, but not hard enough to trigger the explosive inside. This avoids the blast interference that degrades the main charge in traditional designs. Saab said the concept was validated through 50,000 AI-driven digital simulations of warhead-to-armor interactions. The round penetrates up to 700mm of rolled homogeneous armor at an effective range of 700 meters.

The HEAT 758 also introduces Firebolt, a digital communication link between the munition, the Carl-Gustaf M4 launcher, and the Fire Control Device 558. The system reads ammunition type and propellant temperature to calculate an optimized ballistic solution before firing. Each round weighs about 7 kg and measures under one meter, with a carbon composite sleeve and titanium barrel liner. Saab confirmed the HEAT 758 is already in production for an undisclosed customer. The Carl-Gustaf is in service with more than 40 armed forces worldwide and has seen heavy use in Ukraine, where defeating ERA-equipped Russian armor at infantry range remains a central tactical problem.

ArianeGroup and Thales completed the first firing of their FLP-T 150 ballistic munition, three weeks after rival MBDA and Safran fired Thundart at the same range. Both rounds are competing under France's FLP-T program to replace the Army's nine aging Lance-Roquettes Unitaires by 2030. The FLP-T 150 uses propulsion and guidance technology derived from ArianeGroup's M51 submarine launched ballistic missile, following a ballistic trajectory with terminal maneuvering via rear-mounted fins for accuracy in GNSS jammed environments. Range exceeds 150 km. The X-Fire launcher, developed by Thales and Soframe, is designed to fire both the sovereign FLP-T round and foreign munitions, and integrates into the existing ATLAS artillery command network. The launcher's own demonstration firings are expected before the end of May. Like Thundart, the system is fully ITAR-free.

L3Harris deployed its Deceptor EW payload on multiple drones during a US Army experiment, demonstrating a system that autonomously detected, geolocated, and jammed hostile RF emitters without human direction. The payloads operated within DiSCO, L3Harris's distributed spectrum operations ecosystem, which fuses data from multiple airborne sensors in real time and coordinates electronic attack at machine speed. Deceptor is built around commercial hardware in a form factor small enough for Group 1 and 2 drones. The design is intended to make EW a volume play rather than a specialist capability: cheap enough to lose, numerous enough to saturate. In a separate March demonstration, L3Harris integrated DiSCO with Shield AI's Hivemind autonomy software, linking electromagnetic battle management directly to autonomous drone flight control.

I read every message and would love to hear what's working, what's missing, or what you want to see more of.
