TOKYO (AP) — Nearly every navy with a presence in Southeast Asia is involved in the extensive search for the Malaysia Airlines Boeing 777 that disappeared early Saturday. Some details on the key responders and their capabilities:
The U.S. Navy is easily the biggest and best equipped Navy in the Pacific and was fast to participate. Two San Diego-based destroyers have been searching areas designated by the Malaysian government. The USS Kidd searched the southwest section of the Gulf of Thailand before heading to the Strait of Malacca as of Thursday, according to 7th Fleet spokesman Cdr. William Marks. The USS Pickney searched the northeast area, between Thailand, Cambodia and Vietnam before heading to Singapore for maintenance.
The Kidd's two HM-60R Seahawk helicopters flew sorties from dawn to dusk in search of debris. They can search a 400- to 600-square-nautical mile area during a typical 3½-hour sortie, depending on sea and weather conditions and the size of object it's trying to find. Its onboard sensors can detect small objects in the water, in addition to the crew using binoculars or the naked eye. The Seahawks also have forward-looking infrared cameras for night use.
A Navy P-3C Orion aircraft has been searching over both the Strait of Malacca and the Gulf of Thailand. The P-3C can search for extended periods and cover 1,000-1,500 square miles every hour. On-board sensors allow the crew to clearly detect small debris in the water.
Four Chinese naval vessels are joining the effort. The Jinggangshan is the largest in the Chinese navy and has a large flight deck capable of launching several helicopters. An air force plane was dispatched to search for signals from the flight's black box.
The People's Liberation Army Newspaper, run by the ruling party's military commission, said Beijing also sent four helicopters and four civilian search vessels. The Kunlunshan — another amphibious landing ship with two helicopters — arrived at the designated area in the Gulf of Thailand early Thursday morning.
China plans to expand the scope of its search in the northwest toward the Gulf of Thailand and to cover 5,000 square nautical miles (17,000 square kilometers) in the Gulf of Thailand, the military newspaper said.
"That is equivalent to a medium-sized city, and we must be meticulous in our work because of the higher demands to conduct the search in such a vast area," Liu Zhonghu, captain of Jinggangshan, told the newspaper.
On state-run China Central Television, PLA navy officers said the helicopters took off from the Jianggangshan and Kunlunshan to search, the ships were using underwater sonar and robots to detect the plane, and the crews have been surveying the sea.
