Pratt & Whitney
The Pratt & Whitney T-220 is a 10-kW Hall thruster. This thruster was tested at PEPL as a part of the Air Force Integrated High Payoff Rocket Propulsion Technology (IHPRPT) program. A variant of this thruster (T-220HT) established the U.S. Hall thruster power level record when it operated at 21 kW at PEPL. This record stood for a few months until NASA tested its NASA-457M thruster past 50 kW.
