Aircraft programs

Program	Manufacturer
ATRX Space Plane	ATRX
Approx. Mach 5 spaceplane, unmanned and manned variants planned. Concept design.
Blue Origin New Glenn	Blue Origin
Family of two-stage heavy-lift launch vehicles with reusable first stage (capable of 25 flights) whereby post lift-off and seperation, the first stage autonomously descends to a landing platform leaving the second stage engines to ignite and propel the payload into space, then the fairing separates and the payload is delivered into orbit.
Boeing X-37	Boeing Defense, Space & Security
Low-earth orbit, unmanned, reusable spacecraft used to demonstrate reusable space advancements, requires launch vehicle to exit atmosphere then can re-enter and land as a spaceplane (upon re-entry, vehicle is capable of Mach 25). DARPA involvement reflects potential military applications.
Dassault VORTEX	Dassault Aviation
VORTEX: Véhicule Orbital Réutilisable de Transport et d’Exploration, reusable spaceplane program that lands and manoeuvres in space like an aircraft, for advancing space operations and commercial/science/military missions. Includes subscale VORTEX-D (flight demonstrator, 1:3 scale), and VORTEX-S (smart free flyer, 2:3 scale) variants, and full-scale VORTEX-C (cargo), and VORTEX-M (manned) variants. In development.
Dawn Aerospace Mk-II Aurora	Dawn Aerospace
Commercial version of this remotely-piloted, reusable, suborbital rocket plane. Horizontal take off and parabolic flight trajectory at Mach 3+. Remote pilot control with autonomous pilot-assist. Powered by Dawn Aerospace's single pump-fed HTP/kerosene bi-propellant 4300 N thrust rocket engine. In development, including next-generation Mk-IIB with projected Mach 3.5 speed.
ESA Invictus	European Space Agency (ESA)
Reusable, hypersonic, hydrogen-fuelled, research spaceplane, capable of flying at Mach 5, and builds on technology developed through Reaction Engines' SABRE engine (Synergistic Air-Breathing Rocket Engine). In development, lead by European Space Agency (ESA) and Frazer-Nash.
Hypersonix Delta Velos	Hypersonix Launch Systems
Reusable launch system with scalable design that manoeuvres like an aircraft and is able to accelerate from Mach 5 to Mach 12. In development.
ISRO RLV	Indian Space Research Organisation (ISRO)
Unmanned, Mach 5, reusable launch vehicle to help develop hypersonic flight, autonmous landing, air-breathing engine propulsion and powered cruise flight technologies, and lower launch costs. Initial research and engine development conducted with Advanced Technology Vehicle modified sounding rocket (ATV-D Series). Planned test flights: HEX - Hypersonic Flight Experiment (completed, 2016), LEX - Landing Experiment (completed, 2023-2024), OREX - Orbital Return Flight Experiment, and SPEX - Scramjet Propulsion Experiment. In development.
Polaris Spaceplanes Aurora	Polaris Raumflugzeuge GmbH
Two-stage-to-orbit reusable spaceplane with 2 rocket engines and 4 turbofan engines, capable of carrying up to 1,000 kg or 10,000 kg orbital or suborbital / hypersonic payload respectively. Includes Aurora, and Vega spaceplanes, and Aleda, Athena, and Mira demonstrators. In development.
Radian One	Radian Aerospace
Reusable horizontal takeoff and landing, single-stage to orbit spaceplane. In development.
Rocket Lab Electron / HASTE	Rocket Lab
Family of two-stage orbital launch vehicles with modified third Kick Stage for precise payload delivery, features nine Rutherford engines on first stage, single vacuum Rutherford for second stage.
Rocket Lab Neutron	Rocket Lab
Reusable medium-lift two-stage launch vehicle featuring nine Archimedes engines for first stage, one for second stage, and “Hungry Hippo” fairing meaning there is no separation between stages, instead the fairing opens like a clamshell to deploy the second stage from within the first stage and then closes for atmospheric reentry back to Earth. In development.
