The Dew Line points out an industrial design firms renderings of a "future" Sukhoi PAK FA fighter aircraft. The designs are stunning, but at this point they're also purely hypothetical. The actual PAK FA aircraft is anticipated to pull heavily from the design of both the SU-47 and MIG 1.44. originally scheduled to debut in the 2007 time frame the fighter has seen numerous delays. The latest reports put the airframe completion near this August.
