The Department of Defense awards 36-month fellowships for students in selected fields in science and engineering. The purpose is to increase the number and quality of scientists and engineers in the United States. All are meant for students who are beginning their graduate work, and the deadline for each generally is late December or early January of the year preceding the autumn when the student will begin graduate work. Recipients may take their fellowships to any appropriate research institution of higher learning in the United States.
