The B-2 Stealth Bomber is a long-range aircraft designed to fly undetected in enemy airspace, carrying large artillery including nuclear bombs. Its unique design and features allow it to remain inconspicuous, and it can carry up to 40,000 lbs of weapons. The future use of the bomber is uncertain.
The Stealth Bomber, or B-2, is a long-range bomber with the ability to fly almost undetected in enemy airspace, appearing as small as a bird on radar. It can carry large artillery, including nuclear bombs. It is effective at all altitudes, capable of reaching the entire world in just a few hours, and can fly 6,000 nautical miles (11,112 kilometers) without refueling.
The Stealth Bomber was to replace the B-52 bomber and took nearly 10 years and billions of dollars to develop. Northrop Grumman began delivering the first functional B-2 bomber in late 1993. The United States Air Force (USAF) gave the stealth bomber a 90% reliability rating during its first three years of use. Published assessments claimed that two stealth bombers could do the job of 75 other aircraft.
From a visual perspective, the stealth bomber’s “flying wing” build is truly unique. The body of the aircraft is remarkably narrow and flat, giving the appearance of virtually no body. The leading edges are angled at 33 degrees, while the trailing edges form a “W” shape. The aircraft is covered in a black paint with a radar-absorbent coating. The black color helps keep the bomber concealed during night missions.
The overall goal of the stealth bomber is to deliver weapons accurately and quickly without having to engage in combat. To achieve this goal, it has numerous design features. These deviations from conventional aircraft allow it to remain almost undetected in enemy airspace.
To remain inconspicuous, the stealth bomber must be remarkably quiet, both from radar and audio perception. All four engines are buried deep in the plane to muffle sound. Instead of venting exhaust behind like a conventional aircraft, the B-2 cools its exhaust in a special chamber, then vents the cooled exhaust onto the body. This prevents it from being an easy target for heat-seeking missiles and shields it from ground sensors that would detect heat from the bottom of the plane.
The cabin has two crew members. There are three settings for pilots to choose from: takeoff mode, go to war mode, and landing mode. These three functions are changed by operating a three-way switch.
Weapons are stored in bays in the center of the plane. It can carry 40,000 lbs (18,143 kg) of weapons at a time. These include conventional and nuclear bombs, precision-guided munitions such as bunker-busting ground bombs and strategic cruise missiles, gravity bombs, and a wide range of maritime weapons.
The future use of the B-2 Stealth Bomber seems to be a bit unsure. The original USAF plan was for 132 bombers to be in service, but after 35 years there were still just 21. Stealth aircraft in general have been largely admired as the future of military service aircraft, but the purchasing history it has not yet shown whether they will be a major force in the United States or otherwise.
