Boeing Co. absorbed a $426 million blow as it prepares to deliver the first of its delay-plagued aerial tankers to the U.S. Air Force, rattling investors accustomed to turbulence-free results from the world’s largest planemaker.

The latest writedown covers the higher estimated expense of retrofitting eight of the three-dozen-odd KC-46 tankers in various stages of production ahead of final certification. Boeing had already amassed $3 billion in charges developing the aerial refueler based on its 767 jetliner.
