3Dsolve, a developer of simulation technology, is being acquired by defense contractor giant Lockeed Martin.

3Dsolve is privately held.

Terms of the deal were not disclosed.

Lockheed Martin said 3Dsolve will remain based in Cary and be known as the 3D Learning Systems Group.

“The acquisition of 3Dsolve will strengthen our ongoing initiatives in the rapidly growing training and simulation market, allowing us to provide a broader array of solutions and services to our expanding customer base,” said Dale Bennett, the president of Lockheed Martin Simulation, Training & Support.

“This transaction represents a solid strategic fit for our business and will enable us to strengthen our core competencies, leverage the talents of our employee base and support Lockheed Martin Corporation’s long-term strategy of value expansion,” he added.

The Lockeheed Martin (NYSE: LMT) simulation business unit is based in Orlando, Fla.

3Dsolve develops so-called “serious games” technology based on 3D simulation and multimedia software.

Richard Boyd, one of 3Dsolve’s co-founders and its CEO, will serve as director of the 3D Learning Systems Group.

“We are very pleased to join LM STS to address exciting opportunities,” Boyd said in a statement. "With our experience in gaming, visualization and training combined with Lockheed Martin’s expertise and resources, we intend to be the leader in simulation-based learning.”
