The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a heater fluid electric component and other replacement parts, identified by NSN 0Q-4410-016954565-TX. The procurement involves a quantity of 2 each, with delivery terms set to FOB Origin, and is critical due to the part's unstable design and marginal performance during tests, necessitating government source approval prior to contract award. This item is essential for flight operations, and only previously approved sources will be considered for this solicitation, which emphasizes the importance of submitting comprehensive source approval documentation alongside proposals. Interested parties should contact Bridget M. Murphy at (215) 697-5047 or via email at BRIDGET.M.MURPHY6.CIV@US.NAVY.MIL for further details and to ensure compliance with submission requirements.
