Keeping the E-2 Radardome Spinning

The E-2 gearbox transmitter, P/N GRD5629-2, monitors the rotation speed and position of the E-2 Rotordome. Originally developed and manufactured in the early 1960’s for use on the E-2 Hawkeye, this product became increasingly difficult to support over time due to its age and multiple obsolescence issues. To respond to the worldwide demand from E-2 operators to keep this system in service, ASI successfully engineered and developed an updated repair program. This repair program required a complete redesign and production of new test equipment, as well as developing a new supply chain for spare parts. Several component designs needed to be updated to current specifications due to obsolescence with the aging original design.
