AI Contract Overview

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 [phone hidden]). 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.

Full Description

The Government is conducting market research to identify potential sources with the expertise, capabilities, experience, and technical repair data necessary to meet qualification requirements to repair the Solid-State Crystal Controlled Oscillator/Isolator Assembly. The National Stock Number (NSN) and Part Number (PN) are as follows:

NSN 5955-01-089-1801, P/N +1 (555) 000-0000, Oscillator, Crystal Controlled

This RFI is being conducted to identify different potential non-commercial sources in determining if a future contract effort can be competitively awarded and/or awarded on a total or partial Small Business Set-Aside basis. The applicable North American Industrial Classification System (NAICS) code assigned to this effort is 334511 (Search, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing).

The Government does not own the complete technical data package (TDP) or the unlimited rights to the technical data required for manufacture. The original manufacturer of this item is Norden Systems (Northrop Grumman), and a secondary obsolete source is Cobham. To mitigate supply chain risks associated with a single source of supply, avoid obsolescence bottlenecks, and ensure long-term sustainment for the B-52 fleet, the Government's primary objective is to qualify a new, competitive manufacturing source that can deliver a form, fit, function, and interface replacement for this unit. Please note, this is a Request for Information only, the Government is not requesting any proposals in response to this posting.
