It is worth noting here that the lifecycle costs of the medium CTOL option likely would be lower than those estimated in the JFTL. Those numbers were based on an unaugmented fleet of 49 CTOLs needed to meet the gross lift requirements of its chosen scenarios.
The other options discussed in the JFTL are unrealistic, and their merits in relation to the theoretical capabilities of a new tiltrotor and the real capabilities of, say, the A400M would be too marginal to justify their costs.
The estimated cost of $128 billion or more represents a large commitment, particularly when the JFTL indicates that MVM will shorten the closure time of a maneuvering battalion by only 21 hours in comparison to current capabilities of the POR fleet.
