NAVSUP Weapon Systems Support Philadelphia intends to award a sole source repair requirement for an OBIGGS Pack to Sikorsky, with no drawings or data available for additional sourcing. The Government does not own the rights needed to purchase this part from other sources, and only one responsible source is expected to satisfy the requirement. Firms not already approved to manufacture this material must submit a Source Approval Request, though the procurement will not be delayed for SAR approval. Interested organizations may submit capability statements or proposals to the contracting office for consideration. Delivery will be FOB origin, and this procurement is not a total small business set-aside.
