Boeing delivered quarterly earnings that handily topped analysts' expectations on Wednesday.
The company earned $1.11 billion, or $1.59 per share, for the second quarter ended June 30, down from $1.65 billion, or $2.24 per share, a year earlier.
The company's results were hurt by a big charge related to its military tanker program, and cut its 2015 earnings forecast.
The company said last week it would take a $536 million after-tax charge in the second quarter to account for problems with the fuel system on the KC-46A aerial refueling tanker it is developing for the U.S. Air Force.
Core earnings, which exclude pension and other costs, fell to $1.62 per share from $2.42.
Revenue rose 11 percent to $24.54 billion.
Analysts expected earnings of $1.37 per share and revenue of $24.22 billion, according to Thomson Reuters I/B/E/S.
Commercial aircraft deliveries rose 9 percent to 197.
The company said it now expects core earnings of $7.70 to $7.90 per share for 2015, down from its previous forecast of $8.20 to $8.40 per share.
