About this file
This document is a Sources Sought Announcement for Commercial Underwater Breathing Apparatus (UBA) issued by the Naval Surface Warfare Center Panama City Division (NSWC PCD). The announcement outlines the minimum required characteristics and capabilities for the UBA, including that it must be an electronically controlled closed-circuit rebreather (eCCR) or semi-closed-circuit rebreather (sCCR), capable of operating between 0-300 feet of saltwater, and use Calcium Hydroxide as a CO2 scrubbing media. Respondents must be able to provide technical literature, pricing for 10/20/50 unit quantities, production rate estimates, delivery timelines and costs, quality certifications, and preventative maintenance details. This is not a solicitation, but responses may be used to develop a future Request for Proposal (RFP). Responses are requested within 30 days and should be emailed to the identified technical points of contact.

Table I – Required UBA Characteristics
Characteristic Description
Type:Electronically Controlled Closed-Circuit Rebreather (eCCR) OR Semi Closed-Circuit Rebreather (sCCR)
Operational Depth:UBA shall be capable of operating within a depth range of 0 feet of saltwater (fsw) to a depth greater than 300 fsw.
Human Interface –
BMA:
UBA shall be capable of being utilized by means of a Bite Mouthpiece Assembly (BMA) or otherwise known in industry as: Tbit, Mouthpiece Valve, Dive/Surface Valve (DSV), Mouthpiece, etc.
Mounting Interface-
BM:
UBA shall, at a minimum, be capable to be back mounted to the diver; critical controls (i.e. pressure gauges, oxygen manual gas addition valve, diluent manual gas addition valve) shall remain easily accessible and operable by the diver while wearing thick exposure gear. Back mount configuration shall include minimum required gas cylinders onboard the
UBA
CO2 Scrubber Material:
UBA shall be capable of using Calcium Hydroxide (Ca(OH)₂) as a carbon dioxide (CO2) scrubbing media.
UBA should use materials compatible with both Calcium Hydroxide AND Lithium Hydroxide.
CO2 Scrubber Type:UBA shall be capable if using granular style carbon dioxide (CO2) scrubbing media.
Oxygen Control:
If Electronically controlled, UBA shall maintain a specific partial pressure of oxygen within a tolerance band of ±0.15 ata throughout its operational depth rage; if applicable.
If Semi-closed, UBA Shall maintain a partial pressure of oxygen between
0.19 ata and 1.6 ata.
Non-Metallics ID:UBA manufacturer/vendor shall be able to identify all non-metallics used in its construction by part name, part number, material and approximate weight.
Over pressurizationUBA shall not exceed a pressure of 40 cm H₂O while breathing at 62.5 RMV and performing a diluent flush (MAV or second stage)
