Not to excuse it all, because I'm sure there's plenty of waste and fraud, but sometimes militaries/governments need things that are more robust than the seemingly just-as-good civilian alternatives.
Why doesn't Curiosity run on a Dell Inspiron? Why can't the President drive a used Honda Civic? Why can't the drone programs just retrofit toy helicopters?
(Hint: there are good answers to all of these questions.)
As another point, the book Burning Money from the Chairman of Reagan's Committee on Cost Control, J. Peter Grace:
"The Federal government is Burning Money and it is your money. An actual case. One day the US Navy decided to buy a hammer, the kind you buy for $7 at the corner hardware store. To the $7 cost of the hammer, add: $41 to order the hammer and figure out how to use it. $93 to make sure the hammer worked. $102 for "manufacturing overhead. " $37 to make sure there were spare parts for the hammer. $3 for packing the hammer for shipment. $90 for the contractor's general administrative costs. $56 for the finder's fee. $7 for the capital cost of money. The U.S. Navy ended up buying a $7 hammer for $436, and who paid for it? You."
