Most are small shops where compliance paperwork and quoting speed decide who wins work. This guide covers the ecosystem and the systems problems typical for these shops. ## Industries ### Precision machining **Detail:** Aluminum, titanium and stainless components for airframe, avionics housings and ground support equipment, typically in low to medium volumes with first article inspection. ### Sheet metal and fabrication **Detail:** Brackets, enclosures, chassis and welded assemblies for aircraft and defense electronics, with frequent engineering change orders and drawing revisions. ### Electronics and cable assembly **Detail:** Wire harnesses, circuit card assemblies and box builds for military and communications customers, built to IPC workmanship standards. ### Special processes and finishing **Detail:** Anodizing, plating, painting, heat treat and nondestructive testing, often needing NADCAP accreditation or prime approval. ### Defense electronics and systems **Detail:** Radar, communications and sensor subsystems supported by engineering firms and machine shops that supply them. ## Ecosystem ### Northrop Grumman (Bethpage) **Type:** prime contractor **Note:** The successor to Grumman, with a long documented history on Long Island and a supplier base that grew around it. ### Brookhaven National Laboratory **Type:** national laboratory **Note:** A US Department of Energy laboratory in Upton, New York, relevant for advanced instrumentation and engineering suppliers. ### Stony Brook University **Type:** university **Note:** A major research university offering engineering programs and industry partnerships on Long Island. ### Farmingdale State College **Type:** college **Note:** A SUNY college known for aviation, technology and applied engineering programs that supply the local workforce. ### Long Island Association (LIA) **Type:** business association **Note:** A regional business organization that advocates for employers in Nassau and Suffolk counties. ### Long Island Forum for Technology (LIFT) **Type:** technology organization **Note:** A Long Island nonprofit that supports technology companies and workforce development. ### NIST Manufacturing Extension Partnership (MEP) **Type:** federal program **Note:** The national network of manufacturing assistance centers, with a New York state affiliate that helps small manufacturers with improvement and compliance. ### Defense Contract Management Agency (DCMA) **Type:** federal agency **Note:** Oversees contract administration and quality for many defense suppliers. ## Requirements - AS9100 quality management, often flowed down by primes - AS9102 first article inspection reports - ITAR registration with the State Department DDTC for manufacturers of defense articles - DFARS 252.204-7012 and NIST SP 800-171 for controlled unclassified information - CMMC 2.0 for contractors handling federal contract information and CUI - DFARS specialty metals and counterfeit part prevention clauses - NADCAP accreditation for special processes where required ## Sections ### What subcontractors here make and for whom **Body:** Most Long Island aerospace and defense suppliers are small and privately held. They sell build to print parts to primes, to higher tier suppliers and sometimes directly to government programs. A shop may serve commercial aerospace, military and industrial customers at once, which means several quality flowdown sets in one building. Because the region is expensive, shops tend to focus on complex, low volume, high mix work with short lead times rather than commodity parts. Reputation for on-time delivery and clean paperwork matters as much as price. ### Quoting and estimating realities **Body:** Government and prime RFQs arrive as drawing packages with specification callouts, special process requirements, certifications and inspection levels. Estimators must read each flowdown, price material with required certifications, and add cost for first article reports and special process outsourcing. Quote speed is a competitive advantage. A slow quote often loses to a faster competitor, but an unreviewed fast quote can miss a hidden requirement. Capturing past quotes with their actual cost and linking them to the drawing number helps repeat work. **Bullets:** - Price certifications and material test reports into material cost - Outsourced special processes add lead time and need prime-approved vendors - Record actual hours so the next quote for the same part uses real data ### ERP and systems commonly seen **Body:** Small shops commonly run JobBOSS, E2, ProShop or Global Shop Solutions, with ProShop and similar tools popular for integrating quality documents. Mid sized suppliers use Epicor Kinetic, Infor SyteLine/CloudSuite Industrial, DELMIAworks, Plex or NetSuite. Typical pain points are managing drawing revisions against open work orders, keeping certificates and material test reports attached to lots, tracking approved supplier lists, and producing accurate on-time delivery reporting for primes. ### Compliance and data handling **Body:** Defense work puts the burden on the contractor to protect CUI. That includes where drawings are stored, who can access them and which cloud services are used. NIST SP 800-171 controls and CMMC assessment expectations apply to the whole environment, including any AI tooling that touches CUI. A private deployment on the shop's own hardware, or in an approved private cloud, avoids sending controlled data to public AI services. The customer, not the AI vendor, remains responsible for meeting the controls, so involve your compliance lead early. ### Workforce and where private AI helps **Body:** Experienced machinists and quality inspectors are scarce, and knowledge often sits in a few people's heads. AI that answers questions over the ERP and over procedures, drawings and past quotes can shorten onboarding and reduce interruptions to senior staff. It will not replace first article inspection or a quality manager. In a small shop with a tidy ERP, built-in reports may be enough. AI is most useful where data is spread across ERP, shared drives and email and where quoting depends on finding similar past jobs. ## Faq ### What aerospace and defense work is on Long Island? **Answer:** Long Island has a long history with Grumman, now part of Northrop Grumman, and a supplier base of machining, fabrication, electronics and finishing shops. Many serve primes and military programs with build to print parts and assemblies. ### Do Long Island subcontractors need CMMC? **Answer:** Contractors handling federal contract information or CUI face CMMC 2.0 requirements under DoD contracts, with the level depending on the data. Check your contract clauses and talk with your prime and a qualified assessor to confirm which level applies. ### Is ITAR registration required for machine shops? **Answer:** Registration with DDTC is required for companies that manufacture defense articles on the US Munitions List. A shop machining parts to a defense drawing for a prime may fall under it. Confirm with export counsel, as the obligation belongs to the manufacturer. ### Which ERP is common for small aerospace machine shops? **Answer:** JobBOSS, E2, ProShop and Global Shop Solutions are common for small shops, while larger suppliers use Epicor, Infor SyteLine, DELMIAworks, Plex or NetSuite. Choose based on traceability, document control and AS9100 support. ## Search terms long island aerospace manufacturing, long island defense contractors, aerospace machine shops long island ny, AS9100 ITAR machine shop New York, CMMC for small machine shops, ERP for aerospace subcontractors, defense subcontractor quoting software --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
