B52 Stratofortress, Boeing's veteran heavy bomber is still one of America's most effective combat aircraft, 40 years or so after the first examples were delivered to the then Strategic Air Command (SAC). A massive plane with a wingspan of 185 ft, length of over 159 ft and weighing nearly 220 metric tons at full load, yet still capable of barrelling along at 650 mph with it's eight P&W TF33-P-3/103 turbofans mounted in groups of two, and able to fly up to 50,000 ft altitude. Range is equally massive at 8,800 miles without being refueled.
