The Future: Expeditionary
Force 21• naval in character
• distributed operations
• disaggregated operations
• self-sustaining under austere conditions
• extended or indefinite sustainment
• employing more efficient electrical generation and distribution systems, leveraging ground renewableexpeditionary energy systems (GREENS) to maximum extent possible.
Advanced Base Operations Example
• Modular & scalable energy needs; flexible to support different missions
• Very mobile to elude threats; quick tear down and setup; get away from static forward operating bases
• High efficiency sources
• Optimize renewables when able

USMC: Every Clime and Place
• Foot mobile
• Drives size and weight
• Sand and dust
• Shock and vibration
• No “comfort cooling”
• Work at altitude
• Austere conditions; need reliability
• Military fuels / high S
• Work at altitude
• High humidity
• Salt fog
• Work at MILSPEC Temp Ranges
• Easy to operate & maintain

117 pounds of batteries for 72-hour squad mission
Ground Vehicle Platform
Challenges
• Ground vehicles, expeditionary bases, command and control centers, aviation, and even the individual Marines have experienced an exponential growth in power needs
• Growth expected to continue
• Vehicles are currently batteries for other mission applications
• New C4ISR technologies
• Counter-IED jammers
• New weapons
• Future continued growth:
• Silent Watch
• Lasers and advanced
weapons
• Active protection
systems
• Sensors

Ultracompact Reliable
Expeditionary Power
• Why?– Enhanced combat performance had been mirrored by
exponential power growth at the tactical edge. – Disaggregated & distributed operations eliminates
mutual support and reach-back to battalion assets & maintainers• Current portable generators were fielded for intermittent use
with solar systems, but due to power growth for battery recharging, command and control, computers, and weapon systems, there is a critical need for ultracompact, man-portable, near maintenance free & reliable power at the tactical edge.
• Additionally, signature requirements also drive new S&T solutions.
