The US Navy plans to send a second ship to help search for wreckage from an AirAsia jet that apparently crashed off the Indonesian coast, the Pentagon said Tuesday.

Family members of passengers onboard the missing Malaysian air carrier AirAsia flight QZ8501 react after watching news reports showing an unidentified body floating in the Java sea, inside the crisis-centre set up at Juanda International Airport in Surabaya on December 30, 2014. Items resembling an emergency slide, plane door and other objects were spotted during a aerial search on December 30 for the missing AirAsia plane, according to information from the flight. AFP

The USS Fort Worth, a littoral combat ship, is “prepared to deploy from the region from Singapore,” spokesman Rear Admiral John Kirby told CNN.

“That ship can be ready to sail in a day or two,” Kirby said.

An American destroyer, the USS Sampson, has already deployed to the area to aid with international efforts to find debris and bodies from the passenger plane that disappeared with 162 people on board.

The navy also was ready to provide maritime patrol aircraft to “help map the debris field on the surface” as well as sonar equipment if necessary to track down wreckage at the bottom of the sea, Kirby added.

Searchers on Tuesday spotted debris and bodies at sea that were believed to be from AirAsia Flight QZ8501, which disappeared en route from Indonesia’s second city Surabaya to Singapore amid a storm on Sunday.

All indications suggested the jet crashed in the Java Sea southwest of the island of Borneo, officials said.
