The ARROW platform is leveraging our innovative manufacturing approaches tailored for mass production of small (150 kg-class) satellites at significantly lower costs than other systems with comparable capability. ARROW product is derived from our OneWeb Gen1 product.

ARROW’s heritage comes from hundreds of spacecraft being produced on the same active OneWeb Satellites production lines in Florida and Toulouse. Each factory is configured to output a fully assembled and tested satellite from each line every eight-hour shift.
