Why the B-52 Bomber Will Outlive Everything.
Is it possible that the Vietnam-era B-52 bomber flies for 100 years? The aircraft is now seventy-years-old and may fly into the coming decades due to a series of recent and upcoming upgrades.
The Boeing B-52 Stratofortress, sometimes referred to as the BUFF is an American long-range, subsonic, jet-powered strategic bomber. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber is capable of carrying up to 70,000 pounds of weapons and has a typical combat range of around 8,800 miles without aerial refueling. It also is armed with nuclear or precision guided conventional ordnance with worldwide precision navigation capability. It can fly at high subsonic speeds at altitudes of up to 50,000 feet.
