NEXT, the NASA Evolutionary Xenon Thruster project at Glenn Research Center aims to build an ion thruster about three times as powerful as the NSTAR used on Dawn and Deep Space 1.

By 2008, flight qualification models of the thruster were available. NEXT has 6.9 kW thruster power and 236 mN thrust, can be throttled down to 0.5 kW power, and has an ISP of 4190 seconds (compared to 3120 for NSTAR). The thrusters are manufactured at Aerojet and the power-management units at the ETI division of L3 Communications.

The Dual-Stage 4-Grid (DS4G) is an electrostatic ion thruster design developed by the European Space Agency, in collaboration with the Australian National University.

The design was derived from Controlled Thermonuclear Reactor experiments that use a 4-grid mechanism to accelerate ion beams.

RD AMROSS is a supplier of NPO Energomash RD180 rocket engines to United Launch Alliance (ULA) for the Atlas Launch Vechicle. The RD-180 provides the main thrust on the Atlas V launch vehicle made by the United Launch Alliance.

RD AMROSS, a limited liability company, is a U.S. joint venture between Pratt & Whitney Rocketdyne of West Palm Beach, Florida and NPO Energomash of Khimki, Russia. The company is based in Cocoa, Florida. NPO Energomash manufactures the RD-180 rocket engine for RD AMROSS, and provides designing, manufacturing, testing and other services for liquid propulsion rocket engines.

Aerojet was an American rocket and missile propulsion manufacturer based primarily in Rancho Cordova, California, with divisions in Redmond, Washington, Orange, Gainesville (both in Virginia) and Camden, Arkansas.

Aerojet was owned by GenCorp. It was one of the rare companies that provide both solid rocket motors and liquid rocket engines. Its products include a range of motors, from main engines used on a number of NASA vehicles and ballistic missiles, down to station-keeping thrusters for spacecraft. The propulsion devices include rocket motors as large as the EELV Atlas V strap-on rocket boosters.

Aerojet provided almost all of the USA Army's tactical missile rocket motors. They develop and manufacture a range of air breathing ramjet and scramjet engines. They also do research in the area of electric ion and Hall effect thrusters.

Marotta Controls Inc. designs and manufactures fluid control systems, components and actuators designed specifically for the Aerospace, Military, Space and Industrial markets. Applications include aircraft hydraulic systems, high-pressure pneumatics and smart fluid systems on Navy ships, and reaction control systems on launch vehicles and small satellites.

Marotta produce thrusters and isolation valves; cold gas thrusters; regulators; relief valves; check valves.

Draco is a group of hypergolic rocket engines (known as a thrusters) designed by SpaceX for use on their Dragon spacecraft, the upper stage of their Falcon 9 rocket, while the larger Super Draco engines will be used on later versions of the Dragon spacecraft used for crew transport to low-Earth orbit, as well as entry, descent and landing control of the proposed Red Dragon robotic probe to Mars.
