See this from wikipedia, for example: The JSF program was expected to cost about $200 billion for acquisition in base-year 2002 dollars when SDD was awarded in 2001.[56][57] As early as 2005, the Government Accountability Office (GAO) had identified major program risks in cost and schedule.[58] The costly delays strained the relationship between the Pentagon and contractors.[59] By 2017, delays and cost overruns had pushed the F-35 program's expected acquisition costs to $406.5 billion, with total lifetime cost (i.e., to 2070) to $1.5 trillion in then-year dollars which also includes operations and maintenance.[60][61][62] The F-35A's unit cost for LRIP Lot 13 was $79.2 million.[63] Delays in development and operational test and evaluation, including integration into the Joint Simulation Environment, pushed full-rate production decision to March 2024, although actual production rate had already approached the full rate by 2020; full rate at the Fort Worth plan is 156 aircraft annually.[64][65]
