SAIC split itself in two — Leidos became the technology-services half with a new name
Leidos’ corporate roots lie in Science Applications International Corporation, founded in 1969 by physicist J. Robert Beyster as an employee-owned scientific and engineering services company.
SAIC worked heavily with US government customers across defence, intelligence, science and technology.
The early business looks very different from the company visible today. Following the milestones in order shows which decisions changed Leidos’s direction and which capabilities remained constant.
Employee ownership created an unusual government contractor
Beyster built SAIC around broad employee share ownership and technical autonomy, helping attract scientists and engineers to government projects.
The AI era increased the value of capabilities Leidos had already been developing. Compute, data, networking, software or infrastructure that once served narrower workloads became relevant to much larger AI systems.
The 2013 split created Leidos and a new SAIC
The original SAIC separated into two public companies. The larger national-security, health and engineering business adopted the Leidos name, while a services operation continued as SAIC.

Lockheed Martin’s IS&GS business transformed the scale
Leidos combined with Lockheed Martin’s Information Systems & Global Solutions business in 2016, adding large defence and government technology programmes.
The transaction mattered because it changed the shape of Leidos rather than simply adding revenue. It brought additional technology, customers, geographic reach or operating capability into the group and influenced the next stage of its strategy.
Digital modernisation and cybersecurity became core service lines
The company expanded cloud, cyber, data and software work alongside traditional systems engineering and mission support.
This shift also changed how customers consumed the technology. Instead of treating software or infrastructure as a one-off purchase, the relationship became more continuous, with updates, capacity and services delivered over time.
The new name carried an old scientific-services lineage
As of 18 September 2026, leidos is now a major US government technology and engineering contractor. Its history makes the name deceptively young: the corporate lineage and technical culture extend back to the original 1969 SAIC.
For readers following the brand today, the history explains why newer announcements often connect back to technology or business decisions made much earlier.
For TechnologyBlog.co.za, this page is intended to serve as the company-history cornerstone for future Leidos coverage, so product and company-news articles can link back to one factual brand background instead of repeating the full origin story.
