Triple

Target class: unmanned reusable spaceplane
Context triple: [Orbital Test Vehicle, instanceOf, unmanned reusable spaceplane]

• A. reusable spaceplane chosen
  A reusable spaceplane is a winged spacecraft designed to take off, operate, and land multiple times like an aircraft while transporting payloads or crew between Earth and space.
• B. fully reusable launch system
  A fully reusable launch system is a space launch architecture in which all major components (such as boosters, upper stages, and spacecraft) are recovered, refurbished, and flown again, minimizing expendable hardware and reducing per-launch costs.
• C. partially reusable launch vehicle
  A partially reusable launch vehicle is a space launch system in which only some components—such as the first stage, boosters, or engines—are recovered and refurbished for multiple flights, while the remaining parts are expended.
• D. rocket-powered aircraft
  A rocket-powered aircraft is a type of airplane that uses rocket engines for primary thrust, enabling very high speeds and altitudes over relatively short flight durations.
• E. space station resupply vehicle
  A space station resupply vehicle is a spacecraft designed to transport cargo, equipment, and sometimes crew to and from an orbiting space station, supporting its ongoing operations and maintenance.
• F. None of above.
