The Egyptian Air Defence Forces (EADF) recently showcased a new layer of protection for their high-value assets during the Egypt Defence Expo (EDEX) 2025 in Cairo. Held from 1 to 4 December, the event served as the venue for the public debut of the Guardian system, a high-powered electromagnetic (HPEM) weapon developed by Germany’s Diehl Defence. The presence of this technology confirms Egypt as the previously unnamed African customer that Diehl Defence referenced in 2022 when announcing a contract for its SkyWolf HPEM technology.
The Guardian system appeared at the expo, positioned alongside an IRIS-T Surface-to-Air Missile (SAM) launcher, both featuring a matching camouflage pattern. This pairing reflects the specific operational role Diehl Defence envisions for the system. According to manufacturer specifications, the Guardian is designed to protect IRIS-T SL (Surface Launched) batteries against the growing threat of small unmanned aerial vehicles (UAVs). By integrating HPEM technology into the broader air defence network, the EADF aims to counter low-cost, high-volume threats that might otherwise saturate or deplete expensive missile stocks.
Egypt’s acquisition of the SkyWolf follows a substantial expansion of its air defence capabilities. In late 2021, the German government approved the sale of 16 IRIS-T SL batteries to Egypt, a deal that includes various ranges such as the Medium Range (SLM) and potentially the Short Range (SLS) and Long Range (SLX) variants. The first of these batteries made its public appearance during a military parade in October 2024, marking the anniversary of the 1973 war. The arrival of the HPEM component suggests a phased delivery and integration process, ensuring that the primary missile batteries remain protected from close-in drone harassment.
The technical core of the SkyWolf is its large horn antenna, which provides a non-kinetic means of neutralising aerial threats. Unlike traditional electronic warfare systems that may focus on specific radio frequencies, HPEM weapons emit intense bursts of electromagnetic energy. At extended ranges, the system functions as a powerful jammer, disrupting the communication and navigation signals necessary for a UAV to reach its target. However, the system’s most potent capability is evident at shorter ranges. At these distances, the electromagnetic pulses are strong enough to induce currents in the electronic circuits of a drone, leading to permanent hardware malfunctions or total system failure.
This mechanism offers a notable advantage over conventional electronic countermeasures. Modern UAV threats increasingly utilise autonomous flight paths governed by internal inertial navigation or pre-programmed waypoints, making them immune to standard GPS jamming. Furthermore, some specialised drones now employ fibre-optic cables for control links to avoid radio frequency detection and jamming. Because the HPEM SkyWolf targets the physical integrity of the electronic components themselves rather than just the signal, it can defeat these autonomous and hard-wired systems. The ability to engage multiple targets simultaneously within the beam of the horn antenna also makes it an effective tool against swarm attacks, where kinetic interceptors would be cost-prohibitive.
The integration of the Guardian system into the EADF demonstrates a calculated response to the changing nature of regional aerial threats. While the IRIS-T SL missiles are highly effective against manned aircraft, cruise missiles, and larger drones, the proliferation of “Class I” small UAVs presents a different set of challenges. These small targets often have low radar cross-sections and can be launched in large numbers. Using a high-end interceptor missile against a commercial-grade drone costing a few thousand dollars creates an unfavourable cost-exchange ratio. The SkyWolf provides a reusable, low-cost-per-shot alternative that preserves the missile inventory for more capable threats.
Diehl Defence has engineered the SkyWolf to be modular, allowing for integration onto various vehicle platforms to maintain mobility alongside the SAM batteries it protects. The system typically includes its own power supply and cooling units to manage the high energy requirements of the electromagnetic emitter. While the exact effective range of the circuit-damaging pulse remains classified, typical HPEM systems of this class operate effectively against small electronics within a range of several hundred meters to a few kilometres, depending on the hardening of the target.
The delivery of the SkyWolf emphasises the deepening defence relationship between Cairo and Berlin. Despite occasional domestic political scrutiny in Germany regarding arms exports to the Middle East, the sale of air defence systems is often viewed as defensive in nature. As of early 2026, Egypt remains the only confirmed African operator of this specific Diehl HPEM technology, positioning the EADF as one of the most technologically advanced air defence organisations in the region.
The use of HPEM technology does involve certain trade-offs. The high power output requires substantial electrical support and can potentially interfere with friendly electronics if not carefully managed through strict frequency deconfliction and directional control. The use of a horn antenna helps mitigate this by focusing the energy in a specific direction, away from the IRIS-T’s own radar and command systems. This directional focus ensures that the “soft-kill” capability of the SkyWolf complements the “hard-kill” capability of the missiles without causing fratricide in the electromagnetic spectrum.
As drone technology continues to evolve, the EADF’s adoption of the Guardian system shows a commitment to maintaining a multi-layered defence posture. By combining the long-reach and precision of the IRIS-T missiles with the wide-area, non-kinetic effects of the SkyWolf, Egypt has created a robust shield capable of addressing everything from high-altitude jets to low-level autonomous drone swarms.
