Electronics Technician Navigation (Submarine) 2nd Class Sergio Valadez responds to a code red announcement to combat a simulated fire in the machinery room aboard USS San Juan (SSN 751), a Los Angeles-class submarine, Sept. 14. San Juan is participating in Exercise Black Widow in the Atlantic to advance the art of theater undersea warfare in a multi-domain environment. Our submarines, surface ships, ASW capable aircraft, and other undersea capabilities work together in a dynamic environment to prepare our teams for challenging operations against near-peer competitors.
