SEYMOUR JOHNSON AIR FORCE BASE, N.C. - From the earliest days of Seymour Johnson Air Force Base to today’s high-tempo operations supporting F-15 airpower, one constant remains quietly vigilant at the gates, on the flightline and across the installation: our military working dogs and the Airmen who stand watch beside them.

The 4th Fighter Wing’s K-9 program has a long and proud history rooted in protection, deterrence and trust. Before advanced sensors and integrated security systems became commonplace, military working dogs provided defenders with an unmatched capability. Their senses, instincts and loyalty offered an edge no technology could replicate. That remains true today.

“As commander of the 4th Security Forces Squadron, I have the privilege of overseeing one of the most specialized and demanding assignments on the installation,” said Maj. Justin Asendorf, 4th Security Forces commander. “Our K-9 teams serve as a force multiplier, extending the reach of our defenders and strengthening our ability to safeguard people, resources and aircraft.”

Military working dogs have supported U.S. military operations for generations, and their role has evolved alongside the mission. At Seymour Johnson, MWD, or K-9, teams have adapted to meet changing threats while remaining grounded in their core purpose: detecting explosives, deterring hostile activity and responding decisively when needed. Whether conducting patrols, supporting flightline security or responding to incidents, these teams operate with precision and discipline.

“The importance of the K-9 mission is directly tied to the success of the 4th Fighter Wing. Our wing’s ability to project F-15 airpower depends on secure operating environments,” said Asendorf. “Every sortie generated, every aircraft launched and every task executed relies on a foundation of safety and protection. K-9 teams ensure that the foundation remains solid.”

Explosive detection dogs play a critical role in protecting the flightline and infrastructure that sustain combat-ready operations. Their presence reduces risk, increases deterrence and enhances our ability to identify threats before they can disrupt the operation. In an era of evolving asymmetric threats, that capability is indispensable.

Equally important are the Airmen behind the leash. K-9 handlers undergo extensive training to build a partnership based on trust, communication and accountability. They are responsible not only for mission execution but also for the health, welfare and readiness of their dogs. This bond is built over countless hours of training, deployments and daily care and is reflected by the professionalism of our Security Forces Airmen.

“Our K-9 teams regularly train alongside installation partners and external agencies to ensure seamless integration during real-world scenarios,” said Staff Sgt. Briana Irven, 4th Security Forces Squadron military working dog trainer. “These exercises reinforce readiness while strengthening relationships across the base and the surrounding community. That collaboration enhances our collective ability to respond effectively, no matter the challenge.”

As we look to the future, the role of K-9 teams will remain vital. Technology will continue to advance, but the unique capabilities of military working dogs and their handlers will stand irreplaceable. They are, and will continue to be, a critical element of how we protect the force and enable F-15 airpower.

The men and women of the 4th Security Forces Squadron K-9 program stand watch so that the rest of the wing can fly, fix and fight. Their service ensures that our mission remains secure and that our Airmen return home safely.
