OB1, or Orbital Baguette One, is HyPrSpace's developing hybrid-propellant microlauncher for small satellites. Its development is supported by the Baguette One suborbital demonstrator. The company's CNES R2D2 contract calls for five launches carrying payloads up to 235 kg to low Earth orbit; that contract requirement is separate from a universal maximum vehicle rating.
