- NEW: Official: The Navy is looking at how it can get the bombs out

(CNN) -- Two U.S. military aircraft jettisoned four bombs near the Great Barrier Reef off the Australian coast last week, the U.S. Navy says.
Now, the Navy is looking at how it can get the bombs out, a U.S. Navy official who declined to be identified told CNN.
The two Marine planes abandoned the bombs Tuesday in the national park containing the natural wonder because they were running out of fuel and could not land with the amount of ordnance on board, the Navy said. The two Marine aircraft were launched from a Navy ship, the USS Bonhomme Richard.
Two of the projectiles were explosive bombs that were disarmed before they were dropped. They did not explode, the Navy said. The other two were inert, or non-explosive bombs, the Navy said.
Australian reef threatened
"The jettison box was selected in a deep channel away from the reef to minimize the possibility of reef damage. However the inert and unexploded ordnance is inside the Great Barrier Reef World Heritage area," the Navy official said. "The Navy knows full well how environmentally sensitive the Great Barrier Reef is, and will do everything to make this right."
The pilots chose an area away from the reefs, which contain 400 types of coral. The area was also deep enough to prevent passing ships from running into the bombs, the Navy said.
The reef is home to 1,500 species of fish and 4,000 kinds of mollusks, according to the United Nations' World Heritage Convention.
It is also a habitat for animals threatened by extinction and is protected as a World Heritage Site.

Reports of the incident drew swift condemnation from one Australian lawmaker, who told the Australian Broadcasting Corporation that the situation was "outrageous."
"I think it's outrageous that we're letting the U.S. military drop bombs on the World Heritage Great Barrier Reef," said Greens Sen. Larissa Waters, according to an article on the Australian network's website. "I mean have we gone completely mad? Is this how we look after our World Heritage area now? Letting a foreign power drop bombs on it?"
