FHE and the Defense Industry
• Defense Environmental Operational Ranges
– High Altitude / Outer space
– Deep Ocean
– Environmental Extremes in Temperature and Pressure
• Extreme thermal and pressure gradients
– High acceleration and deceleration operations
• Critical Factors: ruggedization, performance, reliability, qualification
• From the perspective of the defense industry, recasting electronic components in new form factors introduces new design paradigms, free from the constraints of rigid circuit boards.
• SWaP: In an industry constrained in terms of size, weight, space, and cost, FHE will provide unique solutions to these drivers for Lockheed Martin platforms.

The Importance of Ruggedization
• Driver: Electronics Survivability under extreme conditions
• FHE / Direct Write components face large challenges to integration into high-performance systems,
given the absence of past performance data
• Certification of new materials and technologies for DoD high-performance platforms can take years
• There is a lack of test strategies to ensure long term system reliability for defense applications
• Initial applications will find use in secondary, noncritical systems, and in platforms with less stringent
requirements
– Unmanned vehicles
– Sensor platforms
– Energy harvesting
– Conformal antennas
• Demonstration in operational environments is key
• Ruggedization = Reliability! Stringent V&V of FHE in extreme environments will lower hurdles to qualification
for defense platforms
