Which US-based AST SpaceMobile communication satellite did ISRO launch from Sriharikota (Andhra Pradesh) in 2025 ?
BlueBird Block-2
The satellite ISRO launched from Sriharikota for the American company AST SpaceMobile is BlueBird Block-2. It went up on the GSLV-F15 class mission through NewSpace India Limited, ISRO's commercial arm.
BlueBird Block-2 is a direct-to-device communications satellite: it unfolds a very large phased-array antenna in orbit so that an ordinary unmodified mobile phone on the ground can connect to it without any special terminal. That is why it needed a heavy-lift slot rather than a small launcher.
The other names belong to different operators. Starlink V2 satellites are SpaceX's own broadband constellation, BlueWalker 3 was AST SpaceMobile's earlier prototype flown on a SpaceX rocket rather than from Sriharikota, and OneWeb Gen-2 refers to the next phase of the Eutelsat OneWeb constellation.
Hence, the answer is BlueBird Block-2.
