Description

The Government is conducting market research to identify potential sources that possess the repair data, expertise, capabilities, and experience to meet qualification requirements to purchase the B-52 APQ-166 Magnetron/Electron Tube. The National Stock Numbers (NSN) and Part Numbers (PN) are as follows: NSN 5960-01-318-0987, PN VMX-1849. The APQ-166 is currently repaired by CPI (88236) under contract FA8539-22-D-0002. The RMC/RMSC code for the APQ-166 is R3/R. This service has been performed multiple times by CPI, which is the original manufacturer of the APQ-166. The technical data required to organically repair or complete the repair is not owned by the Government and is uneconomical to acquire the data by purchase or to reverse engineer the item. No samples are available for potential suppliers to evaluate.
