WASHINGTON D.C. (S&P Global Ratings) April 30, 2020--S&P Global Ratings today assigned its 'BBB-' issue-level rating to Chicago-based aircraft manufacturer and defense contractor Boeing Co.'s proposed senior unsecured notes. The company plans to issue the notes in tranches due 2023, 2025, 2027, 2030, 2040, 2050, and 2060.
