| Summary | A family of medium-lift launchers from SAST serving China's growing SSO/LEO commercial and government satellite demand, with the 6A and 6C variants adding solid boosters or a simplified expendable configuration respectively. | India's most reliable and frequently flown launch vehicle, operational since 1994. Set a world record in Feb 2017 by deploying 104 satellites in a single flight (Cartosat-2D + 103 microsats). Launched Chandrayaan-1 (2008), Mars Orbiter Mission (2013), and Aditya-L1 (2023). The dual C61/C62 failure streak raised concerns about aging solid motor design. The vehicle is on a return-to-flight campaign (not retired): PSLV-C63 (TDS-01 technology demonstrator), with strengthened third-stage/PS3 checks following the expert-committee (FAC) review, is targeted for late June / early July 2026. | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. |
