On July 4, 2026, the United States marks 250 years since the signing of the Declaration of Independence. It’s a time to reflect on our nation’s history and on the generations of Americans who have served this country and advanced the ideals upon which it was founded.

For 78 of those 250 years, Sandia has answered President Harry Truman’s call to “render exceptional service in the national interest.” We have helped shape U.S. history through scientific and technological achievements. We have stepped forward when our nation needed us most, solving hard problems, responding to emerging threats and making the impossible possible.

The stories in this special edition remind us that Sandia’s impact extends far beyond our campuses. Repeatedly, the nation has turned to us for expertise and a willingness to take on challenges that few others can.

We can take pride in the role Sandia has played in our nation’s story. New challenges lie ahead but our purpose remains unchanged. We will continue to serve the nation with the same sense of mission and commitment that has defined Sandia from the beginning.

Everything we accomplish starts with our people. You will see yourselves and your work reflected in the impressive collection on these pages. As our nation marks 250 years of history, these stories remind us that each generation is called to contribute something of its own.

The Sandians who came before us did exactly that, and now it’s our turn to carry this mission forward and add to the American story. It is still being written and, in so many ways, Sandians continue to help write it.
