V Merilni kompositi Model 348 White Knight Two (WK2) is a quadjet cargo aircraft that is used to lift the SpaceShipTwo spacecraft to release altitude. It was developed by Scaled Composites from 2007 to 2010 as the first stage of Tier 1b, a two-stage to suborbital-space manned launch system. WK2 is based on the successful mothership to SpaceShipOne, White Knight, which itself is based on Proteus. With an “open architecture” design and explicit plans for multi-purpose use, the aircraft could also operate as a zero-g aircraft for passenger training or microgravity science flights, handle missions in high-altitude testing more generally, or be used to launch payloads other than SpaceShipTwo. A study of use of the aircraft as a forest fire water bomber has also been mentioned, one that would utilize a large carbon composite water tank that could be quickly replenished to make repeat runs over fires.

V Northrop X-4 Bantam je bil prototip majhnega twinjet letala, ki ga je leta 1948 proizvajala korporacija Northrop. Ni imel vodoravnih repnih površin, odvisno od kombiniranih dvigal in aileronskih nadzornih površin (imenovanih dvigala) za nadzor v odnosih z metom in rolo, skoraj točno na način podobnega formata, raketni pogon Messerschmitt Me 163 nacistične nemčije Luftwaffe. Nekateri aerodinamiki so predlagali, da bi odprava vodoravnega repa prav tako odpravila težave s stabilnostjo pri hitrih hitrostih (imenovanih šok stall), ki so posledica interakcije nadzvočnih udarnih valov s kril in horizontalnih stabilizatorjev. Ideja je bila utemeljena, vendar so sistemi za nadzor letenja tega časa preprečili uspeh X-4.

V Bristol tip 170 Tovorna ladja was a British twin-engine aircraft designed and built by the Bristol Aeroplane Company as both a freighter and airliner. Its best known use was as an air ferry to carry cars and their passengers over relatively short distances. A passenger-only version was also produced, known as the Wayfarer. The Freighter was developed during the Second World War, having attracted official attention from the British Air Ministry, which sought the development of a rugged vehicle capable of carrying various cargoes, including a 3-ton truck. Various changes to the design were made to accommodate their requirements, but being completed too late to participate in the conflict, the majority of sales of the Freighter were to commercial operators. In response to customer demand, an enlarged version to maximise vehicle-carrying capacity, known as the Bristol Superfreighter, was developed.

V Lockheed Model 12 Electra Junior, more commonly known as the Lockheed 12 or L-12, is an eight-seat, six-passenger all-metal twin-engine transport aircraft of the late 1930s designed for use by small airlines, companies, and wealthy private individuals. A scaled-down version of the Lockheed Model 10 Electra, the Lockheed 12 was not popular as an airliner but was widely used as a corporate and government transport. Several were also used for testing new aviation technologies.

V Zvonec X-5 je bilo prvo letalo, ki je bilo sposobno spreminjati zamahe kril med letom. Navdihnila ga je nepreizkušena vojna zasnova P.1101 nemškega podjetja Messerschmitt. V nasprotju z nemškim dizajnom, ki je lahko imel le kot pometanja kril na tleh, so Bellovi inženirji zasnovali sistem elektromotorjev za prilagajanje pometanja med letom.

V Ryan X-13 Vertijet (oznaka podjetja Model 69) je bilo eksperimentalno reaktivno letalo z vertikalnim vzletom in pristankom (VTOL), ki je letelo v ZDA v 1950-ih. Glavni cilj projekta je bil pokazati sposobnost čistega curka, da navpično vzleti, lebdi, preide v horizontalni let naprej in navpično pristane.

V Severnoameriški X-15 je bilo hipersonično letalo na raketni pogon, ki so ga upravljale letalske sile Združenih držav Amerike in Nacionalna uprava za aeronavtiko in vesolje kot del serije eksperimentalnih letal X-plane. X-15 je postavil rekorde hitrosti in višine v 1960-ih, dosegel rob vesolja in se vrnil z dragocenimi podatki, uporabljenimi pri oblikovanju letal in vesoljskih plovil. Uradni svetovni rekord X-15 za najvišjo hitrost, ki jo je kdaj zabeležilo letalo s posadko, postavljen oktobra 1967, ko je William J. Knight letel s hitrostjo 6,72 Macha na višini 102.100 čevljev (31.120 m), hitrost 4.520 milj na uro (7.274 km / h; 2.021 m / s), je ostal neprekinjen od januarja 2019.

V Martin Marietta X-24 was an American experimental aircraft developed from a joint United States Air Force-NASA program named PILOT (1963–1975). It was designed and built to test lifting body concepts, experimenting with the concept of unpowered reentry and landing, later used by the Space Shuttle. Originally built as the X-24A, the aircraft was later rebuilt as the X-24B. The X-24 was drop launched from a modified B-52 Stratofortress at high altitudes before igniting its rocket engine; after expending its rocket fuel, the pilot would glide the X-24 to an unpowered landing.

The Lockheed Martin X-35 je bilo konceptno demonstracijsko letalo (CDA), ki ga je razvil Lockheed Martin za program Joint Strike Fighter. X-35 je bil razglašen za zmagovalca nad konkurenčnim Boeingom X-32, razvita, oborožena različica pa je začela s proizvodnjo v začetku 21. stoletja kot F-35 Lightning II.
