Six U.S. Air Force service members were killed on March 12, 2026, when a KC-135 Stratotanker crashed during operations against Iran, the Pentagon confirmed. Among the fallen are three airmen from the Ohio National Guard’s 121st Air Refueling Wing, stationed at Rickenbacker Air National Guard Base in Columbus. The incident, currently under investigation, marks a significant loss for the Ohio military community and raises questions about the ongoing operation in the region.
The Ohioans identified as casualties are Captain Seth R. Koval, 38, of Stoutsville; Captain Curtis J. Angst, 30, of Columbus; and Technical Sergeant Tyler H. Simmons, 28, also of Columbus. These airmen were integral to the 121st Air Refueling Wing, a unit responsible for providing aerial refueling capabilities worldwide. The loss underscores the risks faced by U.S. Forces involved in the escalating conflict. The crash occurred in western Iraq, according to officials.
Ohio Airmen’s Service and Backgrounds
Captain Seth R. Koval, an aircraft commander with 19 years of military service, was a KC-135R Stratotanker Instructor Pilot for the 166th Air Refueling Squadron. He earned a bachelor’s degree in aviation operations from Purdue University in 2011. Koval’s wife, Heather, shared a statement on Facebook expressing the family’s devastation, describing him as a loving husband, father and dedicated Airman.
Captain Curtis J. Angst, a KC-135 pilot with 10 years of service, was responsible for flying worldwide air refueling, aeromedical, cargo, and passenger operations. He held a bachelor’s degree in aerospace engineering from the University of Cincinnati and initially enlisted in the Ohio Air National Guard on May 6, 2015.
Technical Sergeant Tyler H. Simmons, a boom operator with eight years of service, played a critical role in transferring fuel to receiver aircraft during aerial refueling missions. A 2015 graduate of Eastmoor Academy in Columbus, Simmons’ cousin, Stephan Douglas, described him as “determined” and a “leader” who was pursuing his dream job. Douglas stated, “This was his dream job, and for this to happen, it’s just a sad tragedy.”
The KC-135 Stratotanker and Operation Epic Fury
The KC-135 Stratotanker is a vital component of the U.S. Air Force’s aerial refueling fleet, extending the range and operational capabilities of other aircraft. The aircraft involved in the crash was supporting Operation Epic Fury, the U.S. Campaign with Israel against Iran, which has resulted in over 2,000 deaths in the Middle East since February 28, according to Reuters. The Pentagon has stated the crash was not caused by hostile fire.
The three Ohio airmen were flying alongside three other airmen from the 6th Air Refueling Wing at MacDill Air Force Base in Florida: Maj. John “Alex” Klinner, Capt. Ariana G. Savino, and Tech. Sgt. Ashley B. Pruitt. There were no survivors from the crash, and another refueling tanker involved in the incident landed safely.
Official Reactions and Memorials
Ohio Governor Mike DeWine has ordered flags to be flown at half-staff in honor of the three fallen Ohioans. Expressions of grief and condolences have poured in from politicians across the state and nation. Vice President JD Vance called for prayers for the service members, stating, “a grateful nation mourns their loss.” Columbus Mayor Andrew Ginther extended condolences to the family and friends of Technical Sergeant Simmons, calling his death a tragic loss.
The Ohio National Guard has initiated support services for the families of the deceased airmen. The cause of the crash remains under investigation.
As the investigation continues, the focus remains on supporting the families of the fallen airmen and understanding the circumstances surrounding the crash. The loss of these service members serves as a stark reminder of the sacrifices made by those serving in the U.S. Military. The ongoing operation in the Middle East continues to present significant risks, and the nation awaits further updates on the investigation and the broader strategic implications of this incident.
