U.S. nuclear submarine “USS Ohio” in Guam

With less than 10 days left before the change of government in the United States, tensions continue between the United States and China. After the U.S. F-35B Lightning II fighter jets appeared in the Philippine Sea on the 9th and performed takeoff and landing drills on the deck of the USS America amphibious assault ship, the U.S. military disclosed on the 11th in a rare and high-profile manner that the USS Ohio (SSBN-726), the first ship of the Ohio-class nuclear-powered submarine equipped with 154 cruise missiles USS Ohio (SSBN-726), the first ship of the Ohio-class nuclear-powered submarine equipped with 154 cruise missiles, has been spotted in Guam, a strategic location in the Western Pacific.

The U.S. Navy said the USS Ohio was in Apra Harbor, Guam, on April 4 for a scheduled exercise, but did not disclose more specific details, saying only that the ship is currently in the 7th Fleet area of operations, responsible for defense in the Western Pacific, performing surveillance, training and other critical tasks.

The U.S. military rarely discloses the movement of nuclear submarines, especially cruise missile nuclear submarines, and this is the second time in less than a month that the U.S. military has disclosed the location of the Ohio-class nuclear submarine, which is clearly a deterrent signal. On December 21 last year, the U.S. military announced that another Ohio-class nuclear submarine, the USS Georgia (SSGN-72), had sailed into the Persian Gulf through the Strait of Homodes in a show of force against Iran.

With a submerged displacement of 18,750 tons, the Ohio is 170.7 meters long, has an S8G nuclear reactor, can reach a maximum speed of 48 kilometers per hour while submerged, has a maximum food supply storage of about 60 days, and can carry up to 15 officers and 140 men. The ship is armed with 22 tubes and up to 154 Tomahawk cruise missiles, in addition to torpedoes.

The four best known Ohio-class cruise missile submarines in the world are the USS Ohio, USS Michigan, USS Florida and USS Georgia. Because the U.S. military is in compliance with the nuclear weapons treaty, 22 of the 24 launch tubes of the former Trident I (C-4) ballistic missiles, which were capable of firing nuclear warheads, have been converted to fire the BGM-109 Tomahawk cruise missile, a submarine The BGM-109 is an all-weather subsonic cruise missile with a range of 1,127 kilometers.

On March 19, 2011, during Operation Odyssey Dawn against the Libyan dictatorship, the USS Florida launched 93 Tomahawk cruise missiles to destroy Libyan air defenses, command centers and other strategic targets.
