General Dynamics Mission Systems Insights
What We Do
At General Dynamics Mission Systems, a business unit of General Dynamics, we develop mission critical C4ISR solutions across the land, sea, air, space and cyber domains, but that doesn’t tell our whole story. When downed pilots are isolated in enemy territory, our equipment gives them a lifeline to call home. When a student opens a textbook to learn about the universe, they’re looking at data and pictures sent using our technology. When the government needs to share crucial top-secret information, our products help them keep this information out of the wrong hands. When sailors need to locate underwater mines, our technology allows them to find explosives with unmanned underwater vehicles. Delivering C4ISR technology is what we do but we think why we do it is more important.
