Aviation: Radar Receiver Gets New Processor


The AN/APR-39A(v)4 radar warning system uses the CP-1597B processor, NSN 5985-01-445-6940, as its primary component.

Heads up! That processor is being replaced with a new CP-1597C processor, NSN 5841-01-543-6979. 

Until last year, only a limited number of aviation units were allowed to use the new processor. Now all aviation units are authorized CP-1597C processors for the UH-60A/L, CH-47D/F, AH-64D/F, and H-60M.

If you have any CP-1597B processors on order, they’ll be cancelled. So put in your order for the CP-1597C processor now

The CP-1597C has the same form, fit and function as the old processor, but uses only three circuit cards versus the seven used by the old processor. That reduced size and weight allows for future growth.
