As of May 31, the U.S. Navy's USS Nimitz Carrier Strike Group is still located near Guam, ready to provide emergency assistance to Guam after the typhoon. The U.S. Navy had also planned to send the USS Makin Island Amphibious Readiness Group to Guam, but the U.S. Navy abandoned the plan due to the typhoon that hit Guam and damaged some civilian and military facilities. Typhoon Mawar is the most damaging typhoon to Guam since Typhoon Fengxian hit Guam in 2002. The U.S. Marine Corps is building a radar station, the radome is destroyed, and NASA radar is also damaged. In areas such as US barracks, there was a certain degree of damage. The entire US Marine Corps base, the US Air Force at the Anderson base, it is estimated that the losses will not be small. The typhoon swept through Guam, destroying parts of the island's radome and military installations. Some people say that "more than 95% of the branches and leaves of trees on Guam were blown away by the typhoon", the situation of casualties is not known for the time being, and the US military must have blocked all the damage news.
