Members from engineering and technical support company JT4 and the 418th Flight Test Squadron sit in the mobile control room of the newly created Receiver Simulation Tool. This is where aerial refueling simulation tests are monitored and recorded. The RST is a ground-based system designed to simulate events that happen during aerial refueling between receiver aircraft and new tankers such as the KC-46 Pegasus, Australian KC-30 and Italian 767.
