You are right, a sideways glance at the MH-60L numbers seem most warranted. Any aircraft with the MH designation will cost more due to the nature of the mission, those aircraft are worked very hard their whole lives and are equipped with a number of systems the standard versions aren’t, the numbers simply aren’t believable.
There has to be some context missing. Perhaps the numbers were compiled at a time of low utilization of the airframes, MH-60L have been replaced by the 60M variant, the variants are so dissimilar as far as cockpit layout and systems that it seems unlikely the 60L would still be used in a limited training role, but who knows?
