| Summary | Germany's first orbital-class launcher attempt; its first flight in March 2025 was Western Europe's first orbital launch attempt from the European mainland. A qualification second flight carrying CubeSats and ESA experiments has slipped repeatedly through 2026. | A medium-lift successor to Firefly's Alpha, co-developed with Northrop Grumman, aimed at the national-security and commercial medium-lift gap between small launchers and heavy-lift vehicles. | China's primary geostationary transfer vehicle for over 25 years. Launched communications, meteorology, and navigation satellites including Beidou-3 (GEO/IGSO nodes). Being phased out in favour of Long March 5 for heavier GTO payloads as newer domestic communications satellites grow in mass. |
