A Guide to Leidos Inc NSN Parts

Many modern defense and aviation operations depend on a steady flow of reliable parts to maintain performance and mission readiness. To support these needs, companies like Leidos Inc develop and integrate a wide range of technologies that are engineered to meet strict performance and reliability expectations in critical environments. In this blog, we will explore how Leidos Inc has evolved over time, outline the types of hardware that support its systems, and clarify how FSC and NSN data can connect buyers to relevant part listings from the company.

What Is the History of Leidos Inc?

Leidos Holdings, Inc. emerged from a 2013 corporate split of Science Applications International Corporation (SAIC), a reputable government contractor known for providing engineering, scientific, and technical services to U.S. federal agencies. Following this separation, the newly formed company adopted the Leidos name and expanded its capabilities through strategic acquisitions and program growth, including the high-profile 2016 merger with Lockheed Martin’s Information Systems & Global Solutions (IS&GS) business. These developments have shaped Leidos Holdings, Inc. into a major provider of integrated defense, civil, aviation, and digital solutions that support a broad range of mission-critical government and commercial operations.

What Components Are Commonly Used in Leidos Systems?

A wide range of hardware and electromechanical components are commonly used to maintain and support Leidos Inc NSN parts, including:


  • Knobs: Components like control knobs can be incorporated into Leidos systems to provide operators with manual input interfaces for adjusting settings on various equipment. 
  • Machine Screws: Fasteners like machine screws are often required to secure housings, panels, and internal assemblies within the company’s equipment.
  • Circuit Breakers: Protective devices like circuit breakers are routinely implemented in Leidos systems, as they have the capacity to interrupt electrical flow during fault conditions. 
  • Cable Assemblies: Interconnect solutions like cable assemblies are frequently employed in Leidos systems to enable reliable transmission of power between subsystems.
  • Relays: Electromechanical relays are commonly integrated into the company’s systems to control circuits by opening or closing electrical contacts, enabling automated switching functions within signal control architectures.

How Do FSC Codes Apply to Leidos Inc?

Federal Supply Classes (FSCs) are standardized four-digit classification codes used across U.S. federal procurement and logistics systems to categorize products and certain services. For example, FSC 6930: Operation Training Devices includes systems and components that support simulation and instructional environments, some of which may be associated with training programs developed or supported by Leidos Inc. As Leidos is involved in a wide range of programs across defense and aviation applications, its associated listings span numerous FSC groupings that reflect this broad operational scope.

How Does Leidos Inc Utilize NSNs for Components?

National Stock Numbers (NSNs) are standardized 13-digit identifiers used across U.S. and NATO military supply systems for items that are repeatedly procured by federal agencies. As Leidos primarily supports U.S. government and military applications, many components associated with its programs are cataloged within these systems and receive NSN designations.
