Black Arrow is promoting the development and delivery of an ambitious, disruptive commercial space program to deliver low-cost, reliable, orbital launch services to a global customer base. We will bring together the best expertise, know-how and innovation from high performance automotive, aerospace, space and marine sectors to produce a range of world-class launch vehicles using non-mined materials, non-intrusive infrastructure, cryogenic propellants and ultra-modern flight systems. With our policies of promoting sustainability, we will be the World's first NetZero launch service provider, leading the way in responsible operating practices, actively supporting debris mitigation strategies and pollution-free spaceflight. The mission is to provide high-value, reliable and flexible access to space, with $/kg to orbit as low as possible and in doing so, support the UK as a responsible space launch hardware and service provider. Our initial system will launch single or multiple payloads in the 500kg class into Low Earth Orbits (LEO), with first launches planned for early 2023, from a specialist seaborne launch facility: our Horizon spacefleet.
