The Naval Air Systems Command intends to award a sole-source delivery order to Northrop Grumman for software, engineering, and logistics support to integrate the AN/APR-39E(V)2 system as the Electronic Warfare bus controller for Navy aircraft. Northrop Grumman is the sole designer and manufacturer of the APR-39 system, making them the only known source capable of meeting the requirement without unacceptable delays or costs. Performance of services will be at Patuxent River, MD, and Rolling Meadows, IL. No budget amounts or submission timelines are specified in this notice. Interested parties may submit a capability statement for review, but this is not a request for competitive proposals.
