NEW YORK (Standard&Poor's) Feb. 18, 2015--Standard&Poor's Ratings Services today assigned its 'A' issue-level rating to Seattle, Wash.-based aircraft manufacturer and defense contractor Boeing Co.'s proposed $750 million senior unsecured notes. The company plans to issue the notes in three tranches due 2025, 2035, and 2045, and to use the proceeds for general corporate purposes. We do not believe that the proposed transaction would significantly alter the company's credit metrics, and our other ratings on the company remain unchanged. Our ratings on Boeing reflect its position as one of two global producers of large commercial jetliners and as one of the largest U.S. defense contractors. Our ratings on the company also reflect the cyclical and competitive nature
