The Australian Defence Force has been criticised for its phase out of planes it has operated for only a decade in favour of commercial replacements.
"You guys don't really actually have a plan, do you? You have no idea," independent senator Jacqui Lambie told senior Air Force officials at a federal budget inquiry on Wednesday.
"It's really embarrassing for me who wore that uniform."
The Royal Australia Air Force will phase out C-27J Spartan planes just 11 years after the first one landed in Australia, but it is yet to disclose a detailed replacement plan.
The Spartans - which are small enough to land on short, soft runways but can carry troops and equipment - is being phased out just over a decade after they were first brought in.
