found this little gem on another forum I visit, its USADF centric for the replacement to C130E/H. But what I found interesting is revisiting the C27J option,
Replacing the C-130E
Costly Flight Hours | TIME.com
If I'm doing my math correct you are only saving 33% of the cost to move 40% of what a C130J can move with a C27J, that confirms Mr C analysis sometime ago about a battlefield lifter and tactical loads strategic distance. But on the other hand are the loads being moved within the region to the islands full loads ie are the loads greater than 40% of the lift capacity of C130J.
Time Magazine has listed the C130-J as having a costed flight hour of
$14,014 USD(2013) so in theory if a C27J saves 33% you should save approx $4624.62USD, I'm not sure what the current budgeted flight hours per aircraft is but ill say roughly 600hrs. if a 3x regional airlifters were acquired and flown the estimated flight hours, that's a potential cost saving of $ 2774400.00USD per regional lifter.
Is that cost saving worth having 2 types of aircraft in the tactical role?
