| Launch Cost | $46,000,000 |
AST SpaceMobile’s Block 2 BlueBird satellites are designed to deliver up to 10 times the bandwidth capacity of the BlueBird Block 1 satellites, required to achieve 24/7 continuous cellular broadband service coverage in the United States, with beams designed to support a capacity of up to 40 MHz, enabling peak data transmission speeds up to 120 Mbps, supporting voice, full data and video applications. The Block 2 BlueBirds, featuring as large as 2400 square foot communications arrays, will be the largest satellites ever commercially deployed in Low Earth orbit once launched.
This launch will feature a single satellite.
