The Aerion AS2 12-passenger aircraft aimed for Mach 1.6 with a supersonic natural laminar flow wing for a minimum projected range of 4,750 nm (8,800 km).

[1] The company announced at the May 2014 EBACE that it was redesigning its previous Aerion SBJ with a larger cabin, more range, and three yet unspecified engines for a $100 million-plus target price.

[10][11] On December 15, after discussions with Lockheed's Skunk Works, they announced a MoU to explore over a year the joint development of the supersonic business jet: engineering, certification and production.

Lockheed previously developed supersonic aircraft like the F-16, the F-35, F-22, and the Mach 3+ SR-71, and they concluded that the AS2 concept warranted time and resource investment after reviewing Aerion's aerodynamic technology.

[22] In April 2020, Aerion unveiled an updated design for the 12 passenger jet, reaching Mach 1.4 in supercruise with nonafterburning engines, over 5,000 nmi (9,300 km).

[23] Building on the NASA X-59 experience, cruise could be boomless up to Mach 1.2, as thicker air at lower altitude can refract the boom away, but this was the highest drag region for the previous supersonic natural laminar flow wing.

[23] The new substantially cranked arrow delta wing is 79 ft (24 m) wide and has leading and trailing edges flaps for field performance and to meet aircraft noise regulations with reduced engine power.

[23] Partners and suppliers included: Safran for the landing gear and nacelles, GKN Aerospace and Fokker Technologies for the electrical wiring and the empennage structure, Spirit AeroSystems for the forward fuselage, Aernnova for the midfuselage structure, Potez for the doors, Eaton and Parker for systems and components, and Siemens Digital Industries Software for design and development.

[24] The facility would include a $300 million factory,[26] a 110.6 acres (44.8 ha) campus, and production plants capable of building 48 AS2 aircraft per year.

[24] Aerion Park would also focus on green technologies, such as solar and 100% water recycling, to power its operations and leave the lowest environmental footprint possible.

[24] In June 2020, Boeing and Spirit AeroSystems disbanded their AS2 engineering teams due to the impact of the COVID-19 pandemic on aviation, and Aerion had to push its first flight date back from 2024 to 2025.

[29] Wind tunnel tests reached Mach 3, providing high-speed performance evaluations, loads, stability measurements, and control of transonic and supersonic velocities, to complete the preliminary design review.

[35] The engine's high-pressure core is derived from the CFM56, and it matches a new twin fan, low-pressure section for a reduced bypass ratio that is better suited to supersonic flight.

[citation needed] General Electric's intentions on the project were confirmed at the 2018 National Business Aviation Association's annual conference.

[40] Spirit AeroSystems, Safran, GKN, Aernnova, and Potez Aeronautique supply aerostructures, wiring, nacelle, landing gear, and aircraft doors.

Ricci noted that, with the aircraft traveling at Mach 1.2, its boom would not reach the ground, possibly allowing regulators to permit supersonic flight over land.

[43] In March 2021, another fractional ownership company, NetJets, announced that it had acquired purchase rights for 20 AS2s, bringing Aerion's order backlog value to over $10 billion.
