The US Air Force stopped flying the F-111 nearly 15 years ago, while the Royal Australian Air Force has continued flying its F-111s and expected to do so until the end of this year. However, according to media reports, the RAAF has just temporarily grounded its fleet following a problem encountered during an appearance at the Singapore air show last week. The engine on one fighter caught fire in mid-air Feb. 4, but the pilot made an emergency landing without incident. (Some RAAF F-111s made a US appearance in 2006, flying in Red Flag.)

Defense experts say the drone threat represents only part of a larger, looming problem: U.S. air bases in the Pacific are increasingly vulnerable to air attacks.
