No. Just one. The above answer is incorrect, according to the Gundam 00 2nd Mechanics sourcebook released earlier this year, the Arche does indeed have 3 GN Drives. The other 2 Drives are located on each leg, specifically the giant cylindrcal objects jutting from them. The book also further confirms that the Masurao and Susanowo possess 2 GN Drives, which are located on their hips.-SonicSP 07:46, June 10, 2010 (UTC) Though they may probably be GN thrusts.
