OICW System Enhancements
STO III.WP.2000.01
Specific Goal:
• Design, Build and Demonstrate Prototype Micro-Electro Mechanical
Systems (MEMS) based Safe & Arm (S&A) Devices to Include Microscale Firetrain (MSF)
Why?
• Cost for the OICW projectile is high. The S&A contributes significantly to
the cost.
• Large fuze (small payload) limits terminal effects
Payoff:
• Reduced cost –50% over traditional S&A
• Increased lethality and survivability – 75% S&A volume reduction
• Enabling MEMS technology facilitates fielding of OICW and OCSW
