The U.S. Naval Academy won the National Security Agency‘s recent Cyber Exercise, or NCX, an event where cadets contended with a variety of cyber operations challenges.

Cadets from all five U.S. military service academies took part in the three-day exercise that challenged participants in the areas of adversary coordinates tracking, space mission kit protection and U.S. infrastructure defense, NSA said Wednesday.

The event garnered 80 guests during its first two days, and on the third day had additional attendees who were supposed to take part in the Joint Service Academy Summit.

The JSA Summit was cancelled due to a snowstorm in the Annapolis area.

The NSA and U.S. Cyber Command members delivered each exercise’s opening and closing remarks.

Harry Coker, executive director at the NSA, announced on March 21 the winner after the final exercise; then Walter Carter, superintendent at the U.S. Naval Academy, delivered NCX’s closing remarks.

NCX 2019 is expected to take place at the U.S. Air Force Academy in Colorado.
