In order to deliver timely, accurate, and relevant weather information in support of military operations in the air, on land, at sea, or in space, the 557th Weather Wing must work in and through cyberspace — without cyber readiness the weather mission fails. From maintaining the Air Force’s $322 million strategic weather computing complex to managing the flow of weather data to defending against cyber adversaries, about 20 percent of the wing’s Airmen are assigned to cyber roles. Like in the other war fighting domains, there is no guarantee of U.S. dominance in cyberspace. In fact, the 2018 National Defense Strategy calls out cyberspace as a contested domain. Because of this, the 557th WW is taking steps to protect and harden its cyber infrastructure, a tall order considering the complexity of the systems and data streams involved.
