What products does Moog Aircraft Group actually make

Flight control systems are the core of what Moog produces. These are the hydraulic and electronic systems that move the control surfaces on an aircraft — the flaps, rudder, elevators, and ailerons that pilots use to steer and stabilize the plane. Moog designs and manufactures the actuators (the devices that move these surfaces), the valves that control hydraulic pressure, and the electronic control units that coordinate everything together.

Landing gear and braking systems are another major product line. Moog makes the hydraulic cylinders, shock absorbers, and brake components that allow aircraft to land safely and come to a stop. These parts must withstand extreme forces during landing and function reliably over thousands of cycles.

Hydraulic systems and components run throughout modern aircraft. Moog manufactures pumps, motors, filters, and accumulators that move and control hydraulic fluid — the fluid that powers everything from flight controls to landing gear to cargo doors. The company also makes specialized hoses and fittings that connect these components.

Electronic and sensing systems have become an increasingly large part of Moog's business. The company produces sensors, actuators, and control electronics that feed information to the aircraft's flight management systems and autopilot. These components help modern aircraft fly more efficiently and safely.

Who buys Moog Aircraft components and why

Aircraft manufacturers are Moog's primary customers. Boeing and Airbus, the two largest commercial aircraft makers, both use Moog components in their planes. Military aircraft manufacturers including Lockheed Martin, Northrop Grumman, and Boeing Defense also purchase from Moog. When an aircraft manufacturer designs a new plane, they specify which suppliers will provide each major system, and Moog often wins contracts for flight control and hydraulic systems because of its reputation for reliability and engineering capability.

Airlines and maintenance providers are secondary customers. When an aircraft needs repair or overhaul, airlines and maintenance shops purchase replacement parts directly from Moog or through authorized distributors. A single commercial aircraft may need landing gear service or flight control component replacement multiple times over its 20- to 30-year service life, so the aftermarket for parts is substantial.

Military branches and defense contractors also purchase Moog components for military aircraft, helicopters, and unmanned systems. These contracts often involve specialized requirements and long-term supply agreements.

Where Moog Aircraft Group operates and what that means for employment

Moog Aircraft Group operates major manufacturing facilities across multiple U.S. states. The company has significant operations in New York (including the historic facility in Buffalo), Florida, California, and several other locations. Each facility typically specializes in certain product lines — for example, one plant may focus on flight control actuators while another produces landing gear components.

The company also operates facilities outside the United States, including in Europe and Asia, to serve international customers and reduce shipping costs for components. These international operations follow the same quality and engineering standards as U.S. plants.

Employment at Moog Aircraft Group spans manufacturing, engineering, quality assurance, supply chain, and administrative roles. The company regularly hires production technicians, CNC machinists, welders, quality inspectors, mechanical engineers, and software engineers. Many positions require technical training or a degree in engineering or a related field, though some entry-level manufacturing roles require only a high school diploma and willingness to learn on the job.

How Moog fits into the broader aerospace supply chain

Moog is what the aerospace industry calls a Tier 1 supplier — a company that sells directly to aircraft manufacturers and has responsibility for designing and engineering major systems. This is different from a Tier 2 or Tier 3 supplier, which makes smaller components or subassemblies that go into Tier 1 products.

Because Moog is a Tier 1 supplier, it carries significant responsibility for the safety and performance of its products. Aircraft manufacturers conduct rigorous audits of Moog's facilities, quality processes, and testing procedures. Moog must also comply with strict aerospace industry standards, including AS9100 (the quality management standard for aerospace), and must pass regular inspections by the Federal Aviation Administration (FAA).

This position in the supply chain also means Moog's business is tightly linked to aircraft production cycles. When aircraft manufacturers ramp up production, Moog's orders increase. When production slows — as happened during the COVID-19 pandemic and after the 737 MAX grounding — Moog's revenue and workforce contract accordingly.

The difference between Moog Aircraft Group and the parent company

Moog Inc. is the parent company, a diversified manufacturer with divisions serving multiple industries. Moog Aircraft Group is the largest and most profitable division, but Moog Inc. also operates Industrial Group (which makes components for industrial machinery and renewable energy), Space and Defense Group (which makes systems for satellites and space vehicles), and Medical Group (which makes components for medical devices).

When you see "Moog" in news articles or financial reports, the context tells you whether the story is about the whole company or just the aircraft division. If an article discusses commercial aircraft or landing gear, it is usually referring to Moog Aircraft Group specifically. If it discusses earnings or strategy for the entire company, it is referring to Moog Inc.

Why Moog Aircraft Group matters to people outside the aerospace industry

Even if you do not work in aerospace, Moog Aircraft Group affects you if you fly commercially. The flight control systems Moog manufactures are essential to aircraft safety and performance. The company's engineering and manufacturing quality directly influence how reliably and safely commercial aircraft operate.

Moog is also a significant employer in the regions where it operates, particularly in western New York and central Florida. The company's facilities support thousands of jobs and contribute to local economies through wages, taxes, and purchases from local suppliers.

For investors, Moog Inc. is a publicly traded company (ticker symbol MOG), so its financial performance and business strategy are matters of public record. The company's success or struggles in aerospace reflect broader trends in commercial aviation and defense spending.

Frequently Asked Questions

Does Moog make the entire flight control system, or just parts of it?

Moog typically makes major components and subsystems — the actuators, valves, and hydraulic power units — but not always the complete integrated system. Aircraft manufacturers often integrate Moog components with electronics and software from other suppliers. For some aircraft, Moog is responsible for the entire flight control system; for others, it supplies specific components that fit into a larger system designed by the aircraft manufacturer or another supplier.

How do I know if a plane I am flying on uses Moog components?

Most commercial aircraft in operation today use Moog flight control or hydraulic systems, but there is no way to know for certain without access to the aircraft's technical specifications. If you are curious about a specific aircraft type, you can search for the aircraft model and "Moog" together, or contact the airline directly. The airline's maintenance documentation would list the suppliers, but airlines do not typically share this level of detail with passengers.

Is Moog Aircraft Group the same as Moog Inc.?

No. Moog Inc. is the parent company that owns Moog Aircraft Group and several other divisions. Moog Aircraft Group is the division that specifically manufactures components for aircraft. When people refer to "Moog" in an aerospace context, they usually mean Moog Aircraft Group, but the parent company Moog Inc. is the entity that is publicly traded and reports financial results.

What qualifications do I need to work at Moog Aircraft Group?

Requirements vary by role. Manufacturing positions may require a high school diploma and technical training; engineering positions typically require a bachelor's degree in mechanical, aerospace, or electrical engineering. Many positions value experience in aerospace manufacturing, familiarity with quality standards like AS9100, or certifications in machining or welding. The company offers training programs and apprenticeships for entry-level candidates.

How often do aircraft need Moog components replaced?

Replacement intervals depend on the specific component and how heavily the aircraft is used. Landing gear and brakes wear out and require overhaul or replacement every few years. Flight control components are designed to last the life of the aircraft (20 to 30 years) but may need repair or replacement if they fail. Airlines follow manufacturer-recommended maintenance schedules that specify when each component should be inspected or replaced.
