U.S. STRATCOM Commander Air Force Gen. John E. Hyten spoke about the importance of space, nuclear and missile defense modernization at an event held by the Mitchell Institute in Washington D.C. on Tuesday.

General Hyten first explained the role of the U.S. Strategic Command, which is “a global warfighting command whose mission areas include nuclear, global strike, space, cyber, missile defense and electronic warfare and more,” though the General emphasized that the nuclear aspect of that list is their number one priority.

Hyten then explained that STRATCOM is the “most global” of all U.S. military commands, with a dominion that stretches from the ocean floor to 2,300 miles above the earth’s surface and a roster of nearly 184,000 men and women he claims represent the best and brightest America has to offer.

“‘Peace is our Profession’ is the motto for all 184,000 people, and those priorities apply to every element of this command,” the general said. “But nuclear is still the backbone, and it has to be our top priority.”
