Reference excerpt

A reusable launch vehicle has parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as fairings, boosters or rocket engines can also be reused, though reusable spacecraft may be launched on top of an expendable launch vehicle. Reusable launch vehicles do not need to make these parts for each launch, therefore reducing its launch cost significantly. However, these benefits can be diminished by the cost of recovery and refurbishment. Reusable launch vehicles may contain additional avionics and propellant, making them heavier than their expendable counterparts. Reused parts may need to enter the atmosphere and navigate through it, so they are often equipped with heat shields, grid fins, and other flight control surfaces. By modifying their shape, spaceplanes can leverage aviation mechanics to aid in its recovery, such as gliding or lift. In the atmosphere, parachutes or retrorockets may also be needed to slow it down further. Reusable parts may also need specialized recovery facilities such as runways or autonomous spaceport drone ships. Some concepts rely on ground infrastructures such as mass drivers to accelerate the launch vehicle beforehand. Since at least in the early 20th century, single-stage-to-orbit reusable launch vehicles have existed in science fiction. In the 1970s, the first reusable launch vehicle, the Space Shuttle, was developed. However, in the 1990s, due to the program's failure to meet expectations, reusable launch vehicles were reduced to prototype testing. The growth of private spaceflight companies in the 2010s lead to a resurgence of their development, such as in SpaceShipOne, New Shepard, New Glenn, Electron, Falcon 9, and Falcon Heavy. At the same time, the US Boeing X-37 and Chinese CSSHQ military spaceplanes began deploying small satellites. Many launch vehicles are now expected to debut with reusability in the 2020s, such as the US Starship, Neutron, Terran R, Stoke Space Nova, and Eclipse, the Chinese Long March 10 and 12, Tianlong-3, LandSpace Zhuque-3, and the European Maia and Miura 5. The impact of reusability in launch vehicles has been momentous for the spaceflight industry. In 2024, the Cape Canaveral Space Force Station initiated a 50-year forward looking plan for the Cape that involved major infrastructure upgrades (including to Port Canaveral) to support a higher anticipated launch cadence and landing sites for the new generation of vehicles.

Configurations

Fully reusable launch vehicle

Several companies are currently developing fully reusable launch vehicles as of January 2026. Each of them is working on a two-stage-to-orbit system. SpaceX is testing Starship, which has been in development since 2016 and has made an initial test flight in April 2023 and a total of 12 flights as of May 2026. Stoke Space's Nova vehicle is also planned to be reusable. As of June 2026, SpaceX's launch vehicle Starship has made significant progress towards full reuse of the entire launch vehicle, both first and second stages. The Super Heavy boosters have demonstrated capability to return to the launch site where they are caught by a "chopstick system" on the launch tower where they can then be reused. The Starship upper stage has completed six controlled splashdowns in the ocean but has not yet been recovered or reused.

Partially reusable launch systems

Partial reusable launch systems, in the form of multiple stage to orbit systems have been so far the only reusable configurations in use. The historic Space Shuttle reused its Solid Rocket Boosters, its RS-25 engines and the Space Shuttle orbiter that acted as an orbital insertion stage, but it did not reuse the External Tank that fed the RS-25 engines. This is an example of a reusable launch system which reuses specific components of rockets. ULA's Vulcan Centaur was originally designed to reuse the first stage engines, while the tank is expended. The engines would splashdown on an inflatable aeroshell, then be recovered. On 23 February 2024, one of the nine Merlin engines powering a Falcon 9 launched for the 22nd time, making it the most reused liquid fuel engine used in an operational manner, having already surpassed Space Shuttle Main Engine number 2019's record of 19 flights. As of 2026, Falcon 9, Falcon Heavy and New Glenn are the only orbital rockets to reuse their boosters, although multiple other systems are in development. All aircraft-launched rockets reuse the aircraft. Other than that, a range of non-rocket liftoff systems have been proposed and explored over time as reusable systems for liftoff, from balloons to space elevators. Existing examples are systems which employ winged horizontal jet-engine powered liftoff. Such aircraft can air launch expendable rockets and can because of that be considered partially reusable systems if the aircraft is thought of as the first stage of the launch vehicle. An example of this configuration is the Orbital Sciences Pegasus. For suborbital flight the SpaceShipTwo uses for liftoff a carrier plane, its mothership the Scaled Composites White Knight Two. Rocket Lab is working on Neutron, and the European Space Agency is working on Themis. Both vehicles are planned to recover the first stage. So far, most launch systems achieve orbital insertion with at least partially expended multistaged rockets, particularly with the second and third stages. Only the Space Shuttle has achieved a reuse of the orbital insertion stage, by using the engines and fuel tank of its orbiter. The Buran spaceplane and Starship spacecraft are two other reusable spacecraft that were designed to be able to act as orbital insertion stages and have been produced, however the former only made one uncrewed test flight before the project was cancelled, and the latter is not yet operational, having completed eleven suborbital test flights, as of November 2025, which achieved all of its mission objectives at the fourth flight.

Worked examples

Example 1 — a first encounter with Reusable launch vehicle

Start with the simplest possible case. Write down what Reusable launch vehicle claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Reusable launch vehicle before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Reusable launch vehicle ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Reusable launch vehicle

In research: Reusable launch vehicle appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Reusable launch vehicle in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Reusable launch vehicle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Reusable launch systems, Reusable spaceflight technology, Rocket propulsion, so understanding it makes those chapters shorter.
In everyday life: Look for Reusable launch vehicle outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
