The Naval Air Warfare Center Aircraft Division (NAWCAD) Lakehurst, NJ intends to negotiate on a sole-source basis with Aerospace Control Products, Inc. for Portable Oxygen Regulator Test Set (PORTS) hardware components supporting the Royal Australian Air Force F/A-18F and EA-18G Program. PORTS is described as a dissolved oxygen meter kit or handheld oxygen analyzer for testing water quality or medical oxygen equipment such as concentrators. The requirement is pursued under FAR 6.302-1 because only one responsible source is available and no other supplies or services will satisfy agency requirements. This notice is not a request for competitive proposals, though the Government will consider responses and requires System for Award Management (SAM) registration for consideration. The information is subject to change and does not bind the Government to solicit or award a contract; applicable classifications are PSC 4920 and NAICS 334515.
