Over 250 Airmen and 9 F-15 Eagles from the 104th Fighter Wing (FW), Massachusetts Air National Guard (ANG) recently deployed to Tyndall Air Force Base (AFB), Florida, to take part in Weapons Systems Evaluation Program (WSEP), alongside Canadian F-18s, F-35s, F-16s, and F-22s.As told by Master Sgt. Julie Avey, 104th Fighter Wing in the article 104th Fighter Wing Eagles on Target at United States Air Force’s Weapons Systems Evaluation Program, as a part of WSEP, the aircraft are loaded and shoot live missiles. The WSEP evaluates aircraft, weapons delivery systems, the weapons, weapons loaders, aircrew, technical data, and maintenance. The purpose is to gauge operational effectiveness, to verify weapons systems performance, determine reliability, and evaluate capability.(This first appeared in 2018.)“The WSEP does two things,” said Col. Jeffrey Rivers, Commander of the 83rd Fighter Weapons Squadron, Weapons Systems Evaluation Program. “It feeds Combat Air Force’s (CAF) training and readiness. We get air crew experience for the first time subsequent to the events, sounds, sights, smells, and noise of a real missile coming off the jet in a realistic scenario they would find normally in training but now it is with real weapons and real targets to shoot at.”
