This requirement is for the purchase of two proprietary EL motor/brake assemblies for the X-Band Radar system, which supports the rotational movement of the radar at an OCONUS site. The assemblies must be fully tested after modification to meet strict specifications and avoid catastrophic failure. Performance of services is at the OCONUS site, with logistical and technical support provided by AFLCMC/ESGS at Robins AFB GA. No budget amounts or submission timelines are specified in the description. The specialized nature and proprietary design indicate a limited pool of potential suppliers.
