The U.S. F-35 Joint Program Office reports that the jet’s acquisition costs increase in the latest production lots. Average flyaway prices for the F-35A and F-35B rise by more than 11% compared with recent contracts, while the F-35C’s price increases by more than 8%, according to figures cited by outlets covering the program.

Both reports describe the broader context as continuing modernization and sustainment costs that raise the overall acquisition bill for the F-35 program. Times of India characterizes the program as the Pentagon’s most expensive weapons system ever built and links the price movement to modernization efforts and higher sustainment spending. Breaking Defense focuses more narrowly on the production-lot comparisons using Joint Program Office data, without emphasizing additional drivers beyond the cost increase itself.

While the outlets agree on the percentage increases by variant, they differ in emphasis: one highlights program-wide cost drivers and scale, while the other centers on the specific pricing figures for the latest lots.
