Direct peers

• MBDA: European missile consortium (Airbus, BAE Systems, Leonardo) producing air-to-air, surface-to-air, anti-ship, and ground-based air defense systems. Directly competes with IRIS-T in the European air-defense market and is Diehl's most direct competitor in guided missiles.
• Kongsberg Defence & Aerospace: Norwegian defense group producing NASAMS air defense systems (with Raytheon), missiles, and air defense radars. Directly comparable in the European ground-based air defense space and operates with similar NATO-focused defense exposure.
• Rheinmetall: Largest German defense prime, with major exposure to air defense (Skynex), ammunition, and armored vehicles. As a German publicly listed defense peer, Rheinmetall offers the cleanest public-market benchmark for Diehl's defense division.
• Itron: Global smart metering and IoT utility major directly competing with Diehl Metering in AMI/AMR deployments, leak detection analytics, and water utility software platforms.

Broad incumbents

• HENSOLDT: German sensor house supplying TRML-4D radar used within the IRIS-T SLM system, while also offering competing air-defense sensor suites. Operates as both partner (radar supply) and adjacent incumbent in European air defense.
• Raytheon (RTX): US defense prime with Stinger, Patriot, and NASAMS air defense portfolios. Direct global competitor in missile-based air defense and Diehl's partner on Stinger co-production in Europe.
• Thales: European defense and aerospace prime covering missile systems, radar, avionics, and military electronics. Comparable to Diehl Defence and Diehl Aviation across both air defense and aerospace electronics.
• Leonardo: Italian defense and aerospace group partnering with Diehl on ERAP artillery and broader European defense programs. Provides comparable exposure to missiles, air defense, and helicopter avionics.
• Lockheed Martin: Largest US defense prime producing PAC-3, Stinger (now RTX), and global missile/air defense systems. Sets the global benchmark for missile-based air defense economics and competes with IRIS-T in NATO tenders.

Emerging players

• Elbit Systems: Israeli defense electronics and loitering munition producer partnered with Diehl on the SkyStriker offering for German Bundeswehr. Compares on air-defense-adjacent systems and EW/drone defense.
