A Combat Systems Officer (CSO[1]) is a flight member of an aircrew in the United States Air Force and is the mission commander in many multi-crew aircraft. The combat systems officer manages the mission and integrates systems and crew with the aircraft commander to collectively achieve and maintain situational awareness and mission effectiveness. CSOs are trained in piloting, navigation, the use of the electromagnetic spectrum, and are experts in weapon system employment on their specific airframe. Aircrew responsibilities include mission planning, mission timing, weapons targeting and employment, threat reactions, aircraft communications, and hazard avoidance.
In 2006, USAF undergraduate CSOs began attending Initial Flight Training (IFT), a civilian contracted flight training operation under Air Education and Training Command (AETC) auspices, with their USAF undergraduate pilot counterparts at Pueblo Memorial Airport, Colorado, a program that replaced the previous Pilot Indoctrination Program (PIP) at the United States Air Force Academy (USAFA), the previous Flight Instruction Program (FIP) in Air Force Reserve Officer Training Corps (AFROTC), the former Centralized Flight Screening Program for Air Force Officer Training School (AFOTS) graduates (and later USAFA and AFROTC graduates following discontinuation of PIP and FIP) at Hondo Municipal Airport, Texas, and the former Cessna T-41 Mescalero phase in Undergraduate Pilot Training (UPT) that was discontinued in the early 1970s. Initial Flight Screening (IFS) has continued as previously established at Pueblo with the transition of USAF Navs to CSOs.
CSO training merges three previous USAF Undergraduate Navigator Training (UNT) tracks formerly known as the Navigator track, the Weapon Systems Officer (WSO) track and the Electronic Warfare Officer (EWO) track into one coherent training cycle in order to produce an aeronautically rated officer who is more versatile and able to adapt to all spectrums of an airframe. Parallel Navigator and WSO training tracks ended in 2009.
