The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 9 each of the Buffer Cylinder Assembly (NSN 7R-1720-014657848-EY). This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, and new sources must undergo a qualification process as outlined by the Government engineering activity. The Buffer Cylinder Assembly is vital for aircraft launching equipment, and the contract is set aside exclusively for small business concerns, with specific set-aside clauses to be detailed in the solicitation. Interested parties should contact Alexis K. Healy at (215) 697-1143 or via email at ALEXIS.HEALY@NAVY.MIL for further information, and must ensure compliance with the Source Approval Information Brochures to be considered for award.
