The B-29 is one of the most iconic bombers to emerge in the Second World War. It is most widely known for dropping the first nuclear bombs used in war, helping to end the war. This bomber changed the landscape of Japan in World War II by the sheer amount of destruction wrought with just two bombs.

Bombers in general played important roles throughout the conflict. Some were specifically designed for naval warfare and destroying ships while others were meant for decimating enemy artillery or armored units. As such, these bombers carried a wide array of ordnance, including torpedoes, general purpose bombs, and some also carried nuclear bombs. (Also see: every country’s nuclear weapons arsenal, ranked.) 

When the United States entered the war, the tide began to turn in part due to the bombers that were reinforcing Allied troops. U.S. bombers played a role in the D-Day Invasion that helped the Allies gain a foothold in Europe to launch their campaign across the continent. American bombers would go on to support the Allies in many critical battles from the skies as they marched to victory against the Axis powers. 

To determine the least and most mass-produced American bombers from WWII, 24/7 Wall St. reviewed a catalog of World War II aircraft compiled by Military Factory, an online database of military vehicles, aircraft, arms, and more. We only included bombers that served during the war, ranking them based on the grand total produced. Prototypes and concept aircraft were excluded. Supplemental information about year entered service, type, manufacturer, crew size, and top speed also came from Military Factory. 

With 18,000 aircraft produced, the B-24 Liberator was by far the bomber most prolific to emerge from the conflict. Manned by a crew of up to 10, this bomber was outfitted with a series of 12.7mm machine guns in different mounts around the plane, and it could carry up to 8,800 pounds of conventional drop bombs. It was not the fastest aircraft with a top speed of only 290 mph, but it could traverse distances of over 2,000 miles. 

Some of these bombers also doubled as fighter planes capable of engaging other enemy aircraft while still conducting their bombing raids. Others would also play roles as transport for paratroopers.  

The current generation of bombers, the B-2 Spirit, is strictly for stealth bombing and is capable of carrying nuclear ordnance among many other big bombs. As this generation has become more specialized, there is less of a need to produce as many, though the cost of each aircraft is much greater. In the days of World War II, however, bombers flooded the skies and rained down fire on their enemies. (These are the oldest and newest fighter jets used in today’s Air Force.)
