In order for KEW projectiles to reliably destroy hostile ICBMs they must use some form of guidance. To be practical, KEWs must be lightweight, able to withstand high g forces, and insensitive to nuclear and electro-magnetic effects. Laser command guidance can guide a KEW to a target 'basket' area whereupon a strapped-down seeker can guide for a hit-to-kill. Key elements of such a KEW system are a laser detector/processor and lightweight control thrusters. Phase I demonstrated miniature photo-acousto-fluidic elements that detected, processed and demodulated FM laser signals riding on a 1.0 watt/sq. cm carrier. Using laminar digital fluidic logic, the ability to command ON or OFF any one of four thrusters was also demonstrated. In addition, high efficiency (>93%), 10-lb net force, single- and dual-axis fluidic diverter/thrusters, were designed and could result in a 300 - 500 gm fully guided KEW projectile. Recommendations are made for Phase II efforts to build, test and demonstrate the diverters and to integrate a light weight detector. Brassboard cold and warm gas operation should also be demonstrated. The laser detection/processing circuitry needs to be designed to operate with propellant gasses. (fr)
