Since its inception, DSA has played an important role in supporting the U.S. Warfighter. In one of its first major programs in the early 1960s, DSA partnered with the U.S. Department of Defense (DoD) to provide a secure and reliable messaging system for America's fighting forces and our allies. DSA engineers developed the world's first packet switch in the 1960s and helped pioneer the use of electronic messages for the DoD. These innovative solutions have been critical in supporting U.S. fighting forces to command, control, and communicate on battlefields from Vietnam to the most recent conflicts in Iraq and Afghanistan.

The DSA Commitment to Customer Service 

DSA is proud of our customer service track record that is supported by comprehensive independent surveys. Our customers we surveyed overwhelmingly stated that they will refer us and engage with DSA in another program. DSA also received exemplary customer responses when asked if there was anything else that DSA could do to better service their account. We see this as a reflection of our proactive service, and we are dedicated to continuing to drive IT solutions. DSA learned, through our most recent survey, that our customers often see us as a niche provider, so we will work to share the breadth of our services to help create IT solutions to meet your diverse needs.
