Bombers, drones, submarines, the US military deployed three advanced weapons in Guam.

　　

　　B-2 bomber (data)

　　Four b-2 bombers

　　The radar reflection area, which integrate various sophisticated technology, is only 0.1 square meters.

　　The US Air Force recently said: "Four B-2 Ghost bombers from Whiteman Air Force Base in Missouri have been transferred and deployed to Anderson Air Force Base in Guam."

　　The B-2 strategic bomber developed by Northrop Grumman Company can reach 12,000 kilometers without refueling in the air, and 18,000 kilometers once refueling in the air. The air flight time of each mission is generally not less than 10 hours, and the US Air Force claims that it has the ability of "global arrival" and "global destruction". B-2A integrates all kinds of sophisticated technologies, and is praised by experts as "a milestone in the development history of military aircraft in the 20th century" because of its outstanding stealth performance. It is reported that the radar reflection cross section of B-52 bomber is 1000 square meters, that of MIG-29 is 25 square meters, that of B-LB is less than L square meters, and that of B-2A is less than 0.1 square meters, which is only equivalent to the radar reflection cross section of a bird in the sky, which makes it difficult for general radar to find it.

　　The two weapon bays of B-2 can hold Boeing’s rotary missile launchers, which can carry 16 AGM－129 advanced cruise missiles or 16 B61/B83 nuclear bombs, 80 227kg Mk82 bombs, 16 joint direct attack weapons, 16 908kg Mk84 bombs, 36 M117 incendiary bombs and 36 CBU-87/89/97.

　　

　　

　　Global Hawk Unmanned Reconnaissance Aircraft (data)

　　Six Global Hawk unmanned reconnaissance aircraft

　　The most advanced high-altitude long-haul spy fighter can shoot objects only 0.3 meters in size.

　　According to the Air Force Times, the US Air Force will deploy six Global Hawk unmanned reconnaissance aircraft at Anderson Air Force Base in Guam before 2009. In addition, the US military is still discussing with South Korea and Japan in Northeast Asia, Singapore and Malaysia in Southeast Asia, and plans to establish a Global Hawk unmanned strategic reconnaissance base in 11 countries in the Asia-Pacific region.

　　"Global Hawk" is the most advanced high-altitude long-endurance unmanned spy fighter in the world. It can fly continuously for 35 hours at an altitude of about 20,000 meters and a speed of about 630 kilometers per hour. It has certain invisibility and is unlikely to be hit by ground fire. Global Hawk’s aerial voyeurism is extraordinary. It is equipped with an electro-optical camera, an infrared camera and a synthetic aperture radar. It can conduct 24-hour aerial reconnaissance of ground or sea targets, including aerial shooting of targets with a size of 1 meter, and even shooting objects with a size of only 0.3 meter. The latest model of "Global Hawk" will also have the ability to eavesdrop in the air and intercept communication secrets such as military satellites of other countries. Once the "Global Hawk" hunts for information, it can be immediately and automatically transmitted to the US military through the satellite system.

　　Global Hawk also has some weaknesses. With a body of about 15 tons, it is difficult to resist the influence of bad weather. The cruising speed is only about 500 kilometers. Once it is bitten by a fighter or an air defense missile, it is difficult to get rid of the bad luck of being shot down.

　　

　　

　　The first ship of the Virginia class submarine of the US Navy is in the sea trial (data)

　　The noise of the world’s most advanced sonar system of Virginia attack nuclear submarine is only 1/10 of the submarine standard.

　　According to American media reports, the most advanced nuclear submarine of the US Navy, the "Virginia" attack nuclear submarine (see left), may be being deployed to Guam. According to the data of the US Navy, the "Virginia" nuclear submarine with a cost of about $2.2 billion is the first submarine specially developed by the US military to cope with the threat after the Cold War. It has powerful anti-submarine, anti-ship, long-range reconnaissance, special operations and the ability to accurately strike land targets with new Tomahawk cruise missiles. It will gradually replace the US Navy’s "Los Angeles" class attack nuclear submarine. The "Virginia" attack nuclear submarine is 114.8 meters long, with an underwater displacement of 7,800 tons, a diving depth of more than 245 meters and an underwater speed of 25 knots. There is no need to replenish nuclear fuel during its life. "Virginia" is said to be "the quietest submarine in the world", the noise is only 1/10 of today’s submarine standard, and the "Virginia" class in sailing is quieter than the "Los Angeles" class parked on the dock without stopping. "Virginia" submarine has 12 vertical launch tubes and 4 533mm torpedo tubes. The vertical launch tube can launch Tomahawk cruise missiles and Harpoon anti-ship missiles with various warheads. The boat is also equipped with lightning protection system, which has strong anti-torpedo ability.

　　This class submarine "has the most advanced sonar system in the world", which replaces the traditional periscope with the advanced photoelectric mast periscope and is equipped with the most advanced C4ISR combat system. It is said that the computing power of a "Virginia" class nuclear submarine exceeds the sum of the computing power of 65 "Sea Wolf" class submarines. What is particularly interesting is that the boat adopts the latest electronic chart, which can automatically process the data of the detection device, not only mark the azimuth or direction of the underwater target, but also calculate the distance to the underwater target. This is something that all submarines can’t achieve before. (Wang Jun)

　　

　　

　　Xinhua News: The British "Economist" published an article in the first issue on October 27th, entitled "Use your brain instead of bullets". The article said that there has been another round of debate about Iraq and Afghanistan in the United States, which may have a major impact on the West. The ongoing debate within the Pentagon is related to the future model of the US military. Since the alliances and obligations of the United States are spread all over the world, this superpower certainly wants to have a "complete set" of military capabilities, which can cope with all kinds of situations, from all-out wars to small-scale public security operations. However, the exact proportion of different abilities in it has caused more and more controversy, and it may cost a lot of money.
