Joint Electromagnetic Preparedness for Advanced Combat (JEPAC)

Colonel Gregory Wood

Mission Statement

JEPAC partners with the Services and Combatant Commands (CCMD) to identify and assess Joint Electromagnetic Spectrum Operations (JEMSO) capability gaps and vulnerabilities, support development of doctrine, organization, training, materiel, leadership and education, personnel, and facilities (DOTMLPF) mitigation strategies, validate potential solutions, and enhance joint force combat capabilities for air, ground, sea, space, and cyber domains.


JEPAC originated from an Office of the Secretary of Defense (OSD), Director of Operational Test and Evaluation chartered joint test (JT) project, August 2007. During that initial phase, the JEPAC JT developed, tested, and evaluated joint tactics, techniques, and procedures (TTP) to enhance air combat capability in an advanced Electronic Attack (EA) environment. Based on its JT success, JEPAC transitioned to a permanent USSTRATCOM directorate to conduct JEMSO assessments and develop mitigation strategies across all warfighting domains.


JEPAC priorities are derived from a combination of USSTRATCOM Commander's guidance, CCMD Integrated Priority Lists (IPL), emerging enemy technology, threat analysis, foreign exploitation, Service priorities, and joint/OSD initiatives. JEPAC products and solutions include:

  • Operational assessments and JEMSO gap analysis of US Systems
  • Non-materiel solutions: joint and service TTP/CONOPS, Navy Tactical Bulletins, Tactical Supplements
  • Enhanced joint interoperability and integration
  • Improved EW training requirements and capabilities
  • Operationally representative exercise EW environment for test and assessment
  • Improved Service and joint academic curriculum
  • Improved EW modeling and Simulation
  • JEMSO advocacy
  • Recommendations for joint and Service acquisition
