The Navy seeks repair of the Encoder-Decoder, DIG, to meet specified CAGE/reference-number and original manufacturer operational/functional requirements, with authorized distributor status required for award consideration. This is a total small business set-aside under Emergency Acquisition Flexibilities; the award will be bilaterally issued and will be a DPAS-rated national-defense order. Pricing should be submitted for an increased-quantity option, which the Government may add by modification after award (the description references both 365 days and 180 days), and evaluation will be based on lowest aggregate total price including the option. The repaired item must be mercury-free for submarine/surface ship use, marked per MIL-STD-130, packaged per MIL-STD-2073, and supported by inspection/testing and quality records retained for 365 calendar days after final delivery. NAVSUP WSS Mechanicsburg will consider past performance, and document/drawing access may need to be requested through SAM.gov Contract Opportunities.
