The 250k motor that was fired last friday built on the old AMROC designs. The biggest difference was the use of a patented hybrid staged combustion head end design. Here is a quote from the NASA Stennis Space Center press release:

"This particular hybrid motor featured new technologies including a revolutionary new head-end combustion approach and ignition system designed by Lockheed Martin Michoud Space Systems in New Orleans."
