Gulfstream Aerospace will not disclose how many wide-cabin G650s it delivered last year until January 25, when parent company General Dynamics will hold its fourth-quarter investor conference call. Following FAA provisional certification of the G650 in mid-November, the Savannah, Ga.-based aircraft manufacturer reconfirmed plans to deliver 10 to 12 G650s by the end of 2011. Investors are keen to find out if that target was met, especially in light of Gulfstream’s increasing importance to General Dynamics’s future growth.
