ILC Dover

ILC Dover was founded in 1947 in Frederica, Delaware, as a manufacturer of inflatable escape slides for military aircraft. The company later pivoted to producing flexible composite materials and life-support systems for aerospace, including the iconic space suits worn by Apollo astronauts and now being manufactured for NASA's Artemis lunar program. Its headquarters and primary manufacturing facility are in Newark, Delaware. The firm's strategy involves developing engineered solutions spanning multiple industrial sectors. It divides its business into four core segments: Aerospace (space suits, airlocks, and inflatable habitats), Life Sciences (powder containment and sterile processing systems for pharmaceutical manufacturing), Industrial Protection (containment for hazardous materials and cleanroom environments), and Engineered Solutions (custom inflatables and flexible structures). Revenue is derived from government and commercial contracts, not from investment returns. ILC Dover employs approximately 750 people across its Newark facility and a smaller office in North Carolina. The company is privately held but disclosed limited financial information in public records. Its production capabilities include ISO 9001 certified manufacturing, and it has actively invested in expanding aerospace production capacity to support the Artemis program contract. A structural differentiator is ILC Dover's specialization in engineering high-reliability flexible composite materials that must pass extreme environmental qualification tests — a capability scarce enough that it remains a sole-source supplier for many core government programs. Its ownership has changed through a series of private equity transactions, with current majority owner being an affiliate of the private equity firm Golden Gate Capital.
