About this opportunity
The Air Force Sustainment Center is conducting market research via Request for Information to identify qualified sources capable of developing a new supply source for the B-52 Radar Pressurization Unit (RPU), with responses due by close of business September 16, 2026. The Government seeks to mitigate supply chain risk; AeroControlEx Corp. is currently the sole known supplier, and the original equipment manufacturer (Great Lakes Manufacturing Corp.) technical data package is unavailable to the Government.
The RPU is a pneumatic assembly (NSN 1280-00-898-3679, P/N 101-352) consisting of a dehydrator, two-stage piston-type electric-motor-driven air compressor, filter, pressure switches, and relief valves, with dimensions of 15.75" length by 7.90" width by 7.75" height and weight of 22.5 pounds. Operating specifications include low pressure output of 17.0 ± 0.25 PSIA, high pressure output of 24.75 ± 0.25 PSIA, altitude capability to 60,000 feet, operating temperature range of –54°C to +71.8°C, AC power requirements of 115V at 1.8 amps at 400 Hz single-phase, and DC power requirements of 28V at 0.9 amps.
The Government anticipates an immediate need of 13 units with a monthly demand rate of 1.24 units and a 10-year requirement of 161.8 total units. NAICS code 334511 applies (small business size standard: 1,250 employees). Respondents must demonstrate capabilities in high-reliability electromechanical and pneumatic assemblies, military-grade hardware development without complete technical data packages, classified material handling up to Secret classification, component obsolescence mitigation, qualification protocols, and NIST SP 800-171 and DFARS 252.204-7012 cybersecurity compliance. Both large and small businesses, joint ventures, and teaming arrangements are encouraged. Responses should be submitted to Lt. Brenden Collins at brenden.collins@us.af.mil.
Notice text
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.
