Sitting next to the YF-23 at the US Air Force Museum in Dayton, OH (or at least it was a few years ago) is an example of the General Electric YF120. The YF120 was in competition with the Pratt & Whitney YF119; both the YF-23 and the YF120 lost their respective competitions. The YF120 was an advanced engine, capable of efficient operation at low speed as well as supersonic. As shown here, it was equipped with a vectoring nozzle providing pitch axis control. Thrust was around 35,000 pounds.

    One of the engineers in my current squadron was on the Northrup Flight Test Team for the YF-23, and he reported that it performed much better on the GE engines, “It would take off like something out of star wars,” is how he described it.
