P-40's were part of 17th Pursuit Squadron (Provisional), shipped to Philippines, but convoy diverted to Australia.
Some 18 P-40's formed part of the PS. Stories here

Armyairforces speaks of some losses over Java, so 40-674 and 40-675 may be among them. 40-667 apparently written off after ground incident?
