AI Contract Overview

The Department of Defense, through the Common Avionics 407 SCMS/GULBA at Robins AFB, is conducting market research via a Request for Information to identify potential non-commercial sources for the repair and manufacture of the B-52 Radar Pressurized Unit (RPU), NSN 1280-00-898-3679, Part Number 101-352. The primary objective is to mitigate supply chain risks associated with a single source of supply and ensure long-term sustainment for the B-52 fleet. Because the government does not own the technical data package, interested sources must demonstrate the capability to reverse-engineer the unit or develop form-fit-function equivalents from physical samples and technical manuals. The effort is categorized under NAICS code 334511, and the government is evaluating whether a future contract can be awarded as a total or partial Small Business Set-Aside. Technical requirements for the RPU include meeting form, fit, and function standards referenced in T.O. 15A3-3-24-3, with a specific outlet air dew point of -20 degrees Fahrenheit. Qualified sources must be able to perform leak-rate testing under vacuum, vibration testing, and performance validation at a simulated altitude of 60,000 feet. The government estimates a 10-year demand of approximately 161.8 units, with an immediate need for 13 units. Prospective contractors must maintain facilities and personnel cleared for Secret classification and comply with stringent cybersecurity and supply chain standards, including DFARS 252.204-7012, NIST SP 800-171, and AS5553 for counterfeit parts prevention. Responses to this RFI are due by September 16, 2026.

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 B-52 Radar Pressurized Unit (RPU). The National Stock Number (NSN) and Part Number (PN) are as follows:

NSN 1280-00-898-3679, P/N 101-352, Radar Pressurized Unit (RPU)

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.

The original equipment manufacturer for the B-52 RPU was Great Lakes Manufacturing Corp.; however, the Government does not own the technical data package (TDP) or the rights to the data required for manufacture. The Government has identified AeroControlEx Corp. as the only known current supplier for this NSN. To mitigate supply chain risks associated with a single source of supply and ensure long-term sustainment for the B-52 fleet, the Government's primary objective is to develop a new, qualified source for this item. Please note, this is a Request for Information only, the Government is not requesting any proposals in response to this posting.
