Air defence systems are used to protect the population, important buildings, objects as well as ground troops against attacks from the air. Particularly ground-based air defence is capable of providing continuous area protection over the long term. For the Bundeswehr´s Tactical Air Defence System (TLVS), Diehl Defence developed the surface-launched IRIS-T SL, an upgraded version of the IRIS-T missile equipping fighter aircraft of numerous countries worldwide. In combination with various radar and command systems, IRIS-T SL offers the capabilities and benefits of an advanced air defence system. An entire IRIS-T SLM system was tested successfully for the first time in 2014 in the presence of international representatives.

Sky Sphere is a drone defence system whose purpose is the protection of assets against direct attacks carried out by class I and class II UAVs in military conflicts. The system shall be effective against single drones as well as swarm attacks and therefore utilizes an appropriate C2 System combined with suitable sensors and a sufficient number of effectors. The system is able to operate independently as well as in coordination with military units and can be integrated into higher-level systems. The eMissile CICADA is used within the Sky Sphere system. CICADA is an electrically driven missile which is supposed to be deployed with two different payloads. In a non-lethal version, drones are neutralized by a catch net. In a lethal version, a fragmentation warhead is integrated as an effector.

The IRIS-T guided missile was developed as aircraft armament for air-to-air missions within a European cooperation program. The combination of thrust vector and aerodynamic control provides the missile with extremely high agility. An additional technological leap was achieved with the imaging IR seeker head in conjunction with intelligent image processing. Target designation is accomplished by airborne radar or via the pilot's helmet sight. IRIS-T´s outstanding features even permit engaging targets behind the aircraft as well as interception of opponents`missiles. In addition to the consortium partners Germany (pilot nation), Greece, Italy, Norway, Sweden and Spain, further countries worldwide decided to procure IRIS-T. It was selected as standard weapon for the Eurofighter, F-16, EF-18, Tornado and Gripen fighter aircraft.

Guns are part of the standard armament of modern naval vessels. Besides modern conventional solutions, Diehl Defence is offering an innovative, self-guiding projectile. For decades, the 76 mm ammunition used by 20 navies worldwide has proved its effectiveness in the field. An enhanced version with insensitive explosives increases on-board safety. Diehl’s 127 mm full-caliber as well as the 127 mm VULCANO guided ammunition, developed in cooperation with the Italian industrial partner Leonardo, are new products. Both ammunition types can be used to engage sea and land targets at long ranges. Thus, both types are suited for joint tactical fire support operations.
