Survivable Electronics for Control of Hypersonic Projectiles under Extreme Acceleration

Sea Power 21 represents a vision and roadmap for a transformational process which seeks to optimize Naval force employment through integration into joint global operations and align R & D toward specific current and projected warfighter needs. Sea Strike is one of the concepts behind the Sea Power 21 vision. Sea Strike is the ability to project precise and persistent offensive power from the sea and builds upon the asymmetric strengths unique to US Naval forces. Technology now allows Naval forces to decisively engage targets deep inside enemy territory while operating from a remote, secure, mobile afloat base. Electro-magnetic rail guns are one of the key technologies targeted for Future Sea Strike Capability and will contribute in a very measureable way to the ability of the US Navy to execute long range, precise, sustained, time-sensitive, and covert strike missions. Hypersonic guided flight for precision munitions delivery and the related launch survivability for guidance electronics are ONR focus areas. Our proposed shock hardened IMU solution leverages our relevant experience and adapts existing technologies to produce a reliable, compact, cost effective shock hardened and isolation approach for electronic systems subjected to the specific extreme shock environment characteristic of launch from an electromagnetic rail gun.
