Not trying to be a butt head, but this still doesn't ring true and unfortunately some here are going to run with this and potentially embarrass themselves and this board. Willing to do some digging, if you can identify which of the many sources was used to generate the quantity (16k) and cost (78M) for the one line item that is almost 95% of the total cost rollup. Note that if that line item is taken out, then the total $$ falls in line with the 88B reported in other sources. Please help identify the source for this line item, for without that information this is unusable outside of this forum. P.S. Have worked on the development of many MIL systems and this does not add up!
