What the government is buying

The Department of the Navy is procuring duct assemblies for air conditioning and heating systems. This falls under broader aerospace and aircraft manufacturing, specifically components that manage airflow for environmental control systems in military aircraft. NAVSUP Weapon Systems Support Philadelphia, the contracting activity, manages acquisition for naval aviation sustainment.

Duct assemblies in this context are typically precision-fabricated metal or composite conduit systems that channel conditioned air throughout aircraft cabins, cockpits, and equipment bays. These parts must meet strict military specifications for durability, weight, and performance under extreme conditions. The classification code 1660 and NAICS 336413 confirm this relates to aircraft components rather than building HVAC systems.

See the solicitation for exact technical specifications, quantities, and delivery requirements.

Key facts

Who can bid

Any qualifying business may bid—this is a full and open competition with no small business set-aside. Large manufacturers, mid-tier suppliers, and small businesses alike can compete.

For NAICS 336413, typical eligibility thresholds apply: the Small Business Administration generally classifies manufacturers with 1,000 or fewer employees as small. However, because no set-aside applies, size status does not restrict participation.

Bidders must be registered in the System for Award Management (SAM.gov) with active registration through contract performance. Technical capabilities relevant to aerospace duct fabrication—such as AS9100 quality certification, experience with military specifications (MIL-STD, MIL-PRF, or NAVSEA/NAVAIR requirements), and proven manufacturing processes—will likely factor heavily in evaluation.

How to put together a competitive bid

Manufacturing capability documentation: Emphasize your experience with aircraft duct assemblies or similar aerospace environmental control system components. Include past performance on Department of Defense contracts, particularly NAVSUP or NAVAIR awards.

Quality systems: Detail your AS9100 registration, Nadcap special process certifications (welding, brazing, heat treating if applicable), and inspection capabilities. Military aircraft parts demand rigorous quality assurance.

Engineering and technical proposal: Address how you will meet the specific material, dimensional, and performance requirements. Aircraft ductwork often involves aluminum, stainless steel, or titanium with complex geometric configurations.

Pricing strategy: With full and open competition, expect price to carry significant weight. Analyze your material costs, labor rates, and overhead carefully. Consider the Philadelphia place of performance for logistics costs if you must deliver or perform there.

Past performance references: Prepare relevant contract references with similar scope, value, and complexity. NAVSUP Philadelphia evaluates contractor reliability for weapon systems support.
