2. The RN Type 26s have yet to be built, so the unit price when they do will receive the volume cost benefits of the RAN order.

"Stewart said the plan was for the Hunter-class build to follow the Type 26 activity in the U.K. by around five years, which will serve to de-risk the Australian program. BAE is due to deliver the first ship, HMS Glasgow, to the British Royal Navy in 2025, with entry into service in the 2027 time frame.
“We cut steel for the first Type 26 in the U.K. in June 2017, and we’ll cut steel for full production of the Hunter class in South Australia in 2022,” he said. “We’ll run at an 18-month drumbeat in the U.K., and somewhere between 18 months and two years in Australia. That will keep a five-year gap, which is almost perfect. You are de-risking the Australian program in the U.K. and you don’t get the obsolescence issues you would if there was a longer gap, so it’s a really good program overlap.”
