AST SpaceMobile’s BlueBird Block 2 satellites are part of a new class of spacecraft designed for direct-to-smartphone communication from orbit. These satellites are designed to support continuous cellular broadband service, starting with markets such as the United States, and aim to deliver voice, data, and video services directly to unmodified smartphones.
Each Block 2 satellite features a 2,400 sq ft phased-array antenna, placing them among the largest satellite arrays ever deployed in low Earth orbit. The arrays support beamforming with up to 40 MHz per beam and peak data rates of 120 Mbps, capable of supporting high-throughput data services, including video and real-time connectivity.
The performance upgrade is powered by the custom AST5000 ASIC chip, developed with TSMC, which provides up to 10,000 MHz of instantaneous bandwidth while improving power efficiency and reducing cost.
AST SpaceMobile plans to launch up to 60 Block 2 satellites between 2025 and 2026 using multiple launch providers, including Blue Origin’s New Glenn, SpaceX Falcon 9, and ISRO’s GSLV. The first deployment is planned aboard an Indian GSLV mission.
The company is working with network operators such as AT&T, Verizon, Vodafone, Rakuten, and Google, and holds agreements with more than 45 mobile carriers representing nearly 3 billion subscribers. A long-term contract with Vodafone in Europe and Africa extends to 2034 and covers both Block 1 and Block 2 satellite infrastructure.
