USAF mulls cargo planes for bombers

With money getting short and costs of the, just on paper, long way from flying, new  B21 bomber rising, a study group has suggested loading up cargo planes like the C17 with cruise missiles  They carry the missiles in the cargo bay and they launch them in flight out the cargo bay doors.  Nifty.  The cargo planes are all ready bought and paid for and flying now.  If we need more, they are a LOT cheaper than the B21 will be.  They have the range to get to most places we might care about.  The cruise missiles can reach out maybe 1000 miles.  If we give the cargo planes a bit of ECM and have them fly low they can penetrate all but the toughest air defenses. 

   Only real drawback is that cruise missiles are a lot more expensive than iron bombs.  For example Tomahawks go for $1 mil a shot.  For a short war, the cruise missile carrying cargo planes are effective.  For a long war, the stealthy B21 can get in close enough to drop cheap iron bombs, offsetting the higher cost of the B21 airframe.
