Supporting Those Who Serve
Emanating from our nearby Niceville site, the IS4S office in Fort Walton Beach, Florida was founded to meet a growing need for warhead and direct attack munitions expertise. The programs we support, past and present, encapsulate our expanding technology capabilities and our driving priorities: Long Range Standoff (LRSO) missiles, Enterprise Test Vehicles (ETV), Dense Warhead, Joint Direct Attack Munitions (JDAM), BLU-140, and others.
Located just down the road from Eglin Air Force Base, we’re positioned to easily collaborate on complex problems and build meaningful partnerships. Hosting customers in our all-inclusive prototyping facility or taking our personnel, equipment, and expertise on base for face-to-face discussions has been invaluable in our relentless pursuit of excellence.
Our team has a strong foundation of prior military and civil service experience, and we are driven by a deep understanding of the challenges faced by our military today and a shared belief in the importance of supporting those who protect our nation.

Fort Walton Beach Leadership
Russ Klug
Vice President
-
Russ Klug is an IS4S vice president and site lead for the offices in Fort Walton Beach, Florida and Mooresville, North Carolina. He is responsible for a staff of 60 personnel and the execution of over $200M in programs. Russ’s major areas of focus include weapon system design and development, as well as aircraft integration, including development of direct attack and standoff weapon systems.
Prior to his retirement from DAF, Russ was the chief engineer of the Direct Attack System Program Office on Eglin AFB leading the technical development of multiple weapon systems with new innovative technologies and capabilities. The Direct Attack System Program office included the many variants of the Joint Direct Attack Munition (JDAM), supporting component technologies such as Hard Target Smart Fuze.
The most notable weapon system fielded during Russ’s leadership was the Massive Ordnance Penetrator (MOP). Russ led the development of the USAF’s largest hard target weapon system (30,000 lb) through a Quick Reaction Capability (QRC) process and over time transformed the MOP into a weapon inventory system for production and life-cycle sustainment. MOP to this day provides the USAF with the only conventional weapon system that holds the hardest/deepest targets at risk around the world.
Jason Darr
Associate Vice President
-
Jason Darr is a highly accomplished leader specializing in multimillion-dollar program and project management. Currently serving as a program manager at IS4S, he expertly oversees a $150 million aircraft integration project, directing a team of 60 employees and five subcontractors while continuing to competitively negotiate high-value contracts with government and prime contractors.
Known for his strategic planning and operational efficiency, Jason excels in navigating complex environments and fostering collaboration to drive results. His support of Defense Threat Reduction Agency (DTRA) showcased his sharp analytical abilities toward driving test planning and execution while demonstrating proven experience with systems diagnostics, pressure, and temperature, as well as high-speed cameras. Jason has a Bachelor of Applied Science in Program Management from Northwest Florida State College, and extensive experience in contract negotiations, customer engagement, and team development. He consistently delivers value-adding solutions while meeting and exceeding project goals.
Joel House, Ph.D.
Senior Technical Fellow
-
Dr. Joel House is a recognized expert in the processing and analysis of metals for weaponeering applications. He worked for three decades with the Air Force Research Laboratory’s Munitions Directorate at Eglin AFB as their subject matter expert for material science in tank-terminating weapons.
After retiring from civil service in 2019, Joel took a senior engineering position with IS4S and was recognized as a senior technical fellow in 2023. Joel has continued to analyze metallurgical data in support of DoD weapon systems such as the MK 82, MK 83, and LRSO. He is currently conducting developmental work in the use of artificial intelligence and machine learning. Machine learning algorithms are being used to identify patterns in metallurgical processing data for materials such as high-strength low-allow steels.
Joel has a BS in Mechanical Engineering, MS in Metallurgical Engineering, and a Doctorate in Metallurgical Engineering and Material Science. His graduate education was conducted at the University of Kentucky in Lexington, Kentucky.
Brad Pattullo
Senior Technical Fellow
-
With over four decades of extensive experience in munitions systems, Brad Pattullo has established a distinguished career in the defense sector, particularly within the U.S. Air Force (USAF) and its supporting agencies. Beginning as a munitions systems specialist in the USAF from 1977 to 1997, Brad honed his expertise in missile systems, fuzes, and the development of energetics at Eglin Air Force Base (AFB). Throughout this period, he collaborated closely with various military branches and research organizations, including the Air Force Research Laboratory (AFRL), to advance weapon systems and ensure the effective integration of new energetics into operational capabilities.
Since transitioning to a contractor role at Eglin AFB in 1997, Brad has served as a subject matter expert, contributing significantly to systems engineering, logistics, and production processes for munitions systems. He played a pivotal role in managing and supporting the development and procurement of a wide range of warheads, from the AGM-130 and AGM-142 to various general purpose and advanced munitions. Currently, as a senior technical fellow at IS4S, he leads efforts in weapon development and integration, focusing on research and development (R&D) initiatives for munitions like the BLU-140 and Massive Ordinance Penetrator (MOP). His commitment to enhancing quality and efficiency in munitions production continues to drive innovation and effectiveness in military operations.
