Description
As published on SAM.gov.
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 164-029-0001, 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.
