[22] In August 2012, NASA announced new agreements with the Sierra Nevada Corporation and two other companies to design and develop the next generation of U.S. human spaceflight capabilities, enabling a launch of astronauts from U.S. soil in the next five years.

As part of this agreement, Sierra Nevada Corporation was awarded $212.5 million, ostensibly to continue the development and testing of its Dream Chaser spacecraft.

[24] In July 2014, the corporation signed a letter of cooperation with Tuskegee University to collaborate on efforts related to SNC's Dream Chaser.

[25] In August 2014, Lockheed Martin and Sierra Nevada Corporation unveiled the composite airframe of the Dream Chaser, which was used to conduct the first orbital launch in 2016.

While the Dream Chaser was designed to carry passengers, they modified it for cargo and worked through Thanksgiving 2015 to meet a January 2016 bidding deadline.

[36] The corporation was the main contractor on RocketMotorTwo for Virgin Galactic's SpaceShipTwo, and designed the rocket engine for Scaled Composites, including the one used for SpaceShipOne.

In late November, the corporation announced the permanent closure of their Poway, California propulsion development facility as they intend to consolidate all propulsion activity in one location, at the facilities at Orbital Technologies Corp.[39] In October 2014, the United States Department of Defense awarded Sierra Nevada Corporation's Space Systems with a contract to develop and build a next-generation science and technology demonstration satellite, known as STPSat-5, for their Space Test Program.

The system has flown long-duration sorties daily in multiple theaters since March 2011, providing thousands of hours of direct combat support.

The fully upgraded system simultaneously provides a four-fold increase in area coverage with a two-fold improvement in resolution compared to its predecessor.

[57] The Sierra Nevada Corporation Transport Telemedicine System is a capability that captures and communicates patient care and condition information beginning at the point of injury and continuing until arrival at a medical facility.

In September 2014, at the inaugural Nevada Telemedicine Summit, SNC successfully demonstrated the capability to the U.S. Army Medical Material Agency.

In 2016, United States Customs and Border Protection (CBP) awarded SNC a $280 million firm-fixed-price contract to engineer and integrate 12 Multi-Role Enforcement Aircraft.

[60] In 2020, CBP Air and Marine Operations (AMO) issued a delivery order to SNC valued at roughly $47 million for the acquisition of two Multi-Role Enforcement Aircraft (MEA).

[61] Operators: In 2015, Sierra Nevada Corporation acquired 328 Support Services GmbH (328 SSG) and with it the maintenance rights and type certificates for the Dornier 328 and Fairchild-Dornier 328JET.

[46][72][73][74] In 2004, then-Nevada house representative and Armed Services Committee member Jim Gibbons promoted SNC to receive a $4 million no-bid helicopter technology development contract.

[75][76][77] In 2009, SNC was tied to lobbying scandals from the PMA Group and Indiana congressman and House Appropriations Subcommittee on Defense member Pete Visclosky.

[78][79][80][81][46][82][83] In 2020, SNC's Multi-Agency Collaboration Environment (MACE) group produced a report shared among the Department of Defense and Congress attempting to demonstrate that the Wuhan Institute of Virology shut down for several days in October, providing evidence for the COVID-19 lab leak theory.

[84] The report came under heavy criticism and was the subject of a rebuttal in The Daily Beast, which pointed out that the shifting patterns in cell phone data were easily explained by observable road construction.
