Sukhoi-Gulfstream S-21 was a projected Russian-American supersonic business jet.
In the early 1990s, Gulfstream Aerospace and the Sukhoi Design Bureau began a joint effort to develop a supersonic small business jet, code named the S-21. Due to questionable market demand for commercial supersonic air travel, commitment to the project weakened and delays mounted. [1]
Gulfstream eventually dissolved the partnership, although Sukhoi continued work on the S-21.
The S-21 would be capable of sustained cruise at Mach 2+ and much research and development has gone into the management of the troublesome transonic effects phenomena associated with near Mach 1 air speeds.
As of 2012, the project had not received any funding for the 2013-2025 development period and appeared to be cancelled. [2]

The Sukhoi Su-11 was an interceptor aircraft used by the Soviet Union in the 1960s.
The Sukhoi Su-47 Berkut, also designated S-32 and S-37 during initial development, was an experimental supersonic jet fighter developed by the JSC Sukhoi Company. A distinguishing feature of the aircraft was its forward-swept wing that gave the aircraft excellent agility and maneuverability. While serial production of the type never materialized, the sole aircraft produced served as a technology demonstrator prototype for a number of advanced technologies later used in the 4.5 generation fighter Su-35 and current fifth-generation jet fighter Su-57.
The Sukhoi Su-9 was a single-engine, all-weather, missile-armed interceptor aircraft developed by the Soviet Union.
The Sukhoi T-4, or "Aircraft 100", or "Project 100", or "Sotka" was a Soviet high-speed reconnaissance, anti-ship and strategic bomber aircraft that did not proceed beyond the prototype stage. It is sometimes called the Su-100.

The Aerion SBJ is a supersonic business jet project designed by American firm Aerion Corporation. Unveiled in 2004, the designer sought a joint venture with a business aircraft manufacturer before a $1.2–1.4 billion development in 7–8 years. Aerion received 50 letters-of-intent before enlarging the design as the Aerion AS2 in 2014. Powered by two Pratt & Whitney JT8D-219 engines, the $80 million aircraft would transport 8–12 passengers up to Mach 1.6 and up to 4,000 nmi (7,400 km).
The Embraer Lineage 1000 is a variant of the Embraer 190 regional jet airliner, launched as a private jet on May 2, 2006. Manufactured by the Brazilian aerospace firm Embraer, the Lineage is advertised as an "ultra-large" business jet with comfortable seating for 19.
The Bombardier Challenger 800 was the largest super-midsize business jet offered by Bombardier Aerospace. It is based on Bombardier's 50-seat Bombardier CRJ200 LR. The Challenger 850 was the updated version, produced from 2006 to 2015. This aircraft is no longer for sale.
The Tupolev Tu-244 was a proposed supersonic transport (SST) aircraft, developed from the Tu-144. It implemented novel features such as cryogenic fuel to enable flight distances of up to 10.000 km (6.214 mi) and would have carried up to 300 passengers. The project was cancelled in 1993.
The Sukhoi Su-15 was a prototype Soviet all-weather interceptor which never reached production. The designation was later reused for an entirely different 1960s interceptor, see Sukhoi Su-15.
The Sukhoi Su-17 was a prototype Soviet fighter. The name was later reused for an entirely different fighter-bomber, see Sukhoi Su-17.

The Reaction Engines Limited LAPCAT Configuration A2 is a design study for a hypersonic speed jet airliner intended to provide environmentally friendly, long range, high capacity commercial transportation. The aircraft was designed by the British aerospace engineering firm Reaction Engines Limited, who claim it could be developed into a working aircraft within 25 years once there is market demand for it. The aircraft was designed as part of the LAPCAT programme of the European Union, but has not yet been commercially launched.
The Gulfstream G650 is a large business jet produced by Gulfstream Aerospace. The model is designated Gulfstream GVI in its type certificate, and may be configured to carry from 11 to 18 passengers. Gulfstream began the G650 program in 2005 and revealed it to the public in 2008. The G650 was formerly the company's largest and fastest business jet with a top speed of Mach 0.925, having been surpassed by the larger G700.
The Mikoyan-Gurevich Ye-8 was a supersonic jet fighter developed in the Soviet Union, intended to replace the MiG-21. Only two prototypes were built in 1960-61. The original MiG-21's air intakes were moved under the fuselage, freeing up the nose where a larger and more powerful radar, able to deliver longer range air-to-air missiles, could be built in. Canards were built to both sides of the nose, in front of the cockpit,.

The Citation Excel fuselage was stretched and joined with an all-new, larger wing and more powerful Pratt & Whitney Canada PW306C engines for increased maximum takeoff weight. Announced at the 1998 NBAA convention, it made its maiden flight in February 2002, certification was awarded on June 2, 2004, and deliveries began in late September. The improved Sovereign+ was announced at the October 2012 NBAA for a first flight in April 2013 and deliveries in December, with added winglets and an improved flight deck and engines.

It was announced at the 2011 NBAA convention, the prototype first flew on 18 February 2014, it achieved FAA certification on June 5, 2015 and first deliveries begun on August 27. It keeps the Model 680 Sovereign wing, twin P&WC PW306D turbofans and cruciform tail, but its clean sheet stand-up circular fuselage has a flat floor. This new fuselage is kept in the later Cessna Citation Longitude.
