The Pentagon has updated its cost projections for the F-35 Joint Strike Fighter, with the estimated acquisition cost rising to $536.3 billion and the total lifecycle cost dropping to $1.93 trillion. The revised estimates, published in a recent modernized selected acquisition report, account for development and procurement costs, as well as operating costs over the next six decades.
