B-52 Solid-State Crystal Controlled Oscillator/Isolator Assembly

The Department of Defense, through the AFSC PZABA at Robins AFB, is conducting market research via Request for Information FA853926I-APQ166OSC to identify non-commercial sources capable of manufacturing a form, fit, and function replacement for the B-52 Radar Receiver Transmitter Oscillator/Isolator Assembly (NSN 5955-01-089-1801, P/N 164-029-0001). The primary objective is to mitigate supply chain risks and obsolescence bottlenecks associated with the original manufacturer, Norden Systems, and secondary source, Cobham, to ensure long-term sustainment of the B-52 fleet. This effort falls under NAICS code 334511 and is being evaluated to determine if future contracts can be awarded as total or partial Small Business Set-Asides. The required assembly must be a solid-state, voltage-controlled, crystal-stabilized high-frequency signal generator with a minimum frequency range of 8.66 GHz to 9.66 GHz, a tuning voltage of +5 VDC to +25 VDC, and a maximum weight of 1.3 lbs. Critical technical requirements include compliance with Norden specification 000-R-00031 for nuclear survivability and electromagnetic pulse hardness, as it is designated as a Nuclear Hardness Critical Item. Additionally, the unit must withstand 30 g crash safety shock, adhere to strict electrostatic discharge protection practices, and integrate with a UG-136/U flange. Potential sources must demonstrate the ability to handle classified material up to the Secret level and provide documentation of their capabilities, including socioeconomic status and counterfeit parts prevention compliance such as AS5553. Estimated requirements include an immediate need for 6 units, with a projected 10-year total demand of approximately 39.6 units.
