Operation Meetinghouse, conducted on March 9-10, 1945, was the deadliest air raid in history. 334 B-29 Superfortress bombers dropped incendiary bombs on Tokyo, killing 80,000-100,000 civilians and destroying 15.8 square miles of the city.
On the night of March 9-10, 1945, the United States Army Air Forces launched Operation Meetinghouse - the single most devastating air raid in human history. This massive firebombing of Tokyo claimed more lives than either atomic bombing of Hiroshima or Nagasaki, yet it remains less widely known.
The operation marked a turning point in World War II's Pacific theater, employing a new strategy that would forever change the nature of aerial warfare. Under the cover of darkness, 334 B-29 Superfortress bombers flew at unusually low altitudes over Japan's capital, unleashing an inferno that would transform large sections of Tokyo into ash. The raid's death toll estimates range from 80,000 to over 100,000 civilians, making it the deadliest single air raid ever conducted.
Operation Meetinghouse: March 9-10, 1945
#Operation Meetinghouse launched on March 9, 1945, marked a pivotal shift in U.S. bombing strategy against Japan. The operation deployed 334 B-29 Superfortress bombers in a coordinated nighttime assault that fundamentally changed the course of the Pacific War.
Time and Location of the Attack
#The bombing raid began at 12:08 AM on March 10, 1945, targeting the densely populated areas of eastern Tokyo. B-29 bombers flew at altitudes between 5,000 to 7,000 feet, releasing their payloads over a 16-square-mile section of the Japanese capital. The attack continued for 3 hours through the early morning, focusing on the Shitamachi district where residential wooden buildings dominated the landscape.
Strategic Planning and Objectives
#General Curtis LeMay orchestrated Operation Meetinghouse with specific tactical modifications to maximize destruction. The strategic objectives included:
- Removing bomb bay fuel tanks to increase payload capacity
- Flying at lower altitudes to improve bombing accuracy
- Using M-69 incendiary bombs designed for wooden structures
- Targeting industrial zones mixed with civilian housing
- Coordinating waves of bombers in 3-minute intervals
| Operation Statistics | Data |
|---|---|
| Number of B-29s | 334 |
| Attack Duration | 3 hours |
| Target Area | 16 square miles |
| Flying Altitude | 5,000-7,000 feet |
| Bombing Pattern | 3-minute intervals |
The operation's planning emphasized overwhelming force concentration within a confined area to create firestorms. LeMay's strategy departed from conventional high-altitude precision bombing, adopting low-altitude area bombing techniques that proved devastatingly effective against Tokyo's infrastructure.
The B-29 Superfortress Fleet
#The B-29 Superfortress bombers formed the backbone of Operation Meetinghouse, representing the most advanced aerial warfare technology of World War 2. These aircraft played a pivotal role in executing the devastating Tokyo firebombing mission under General Curtis LeMay's command.
Low-Altitude Incendiary Bombing Strategy
#The B-29s operated at altitudes between 5,000 and 7,000 feet during Operation Meetinghouse, a dramatic shift from their standard high-altitude operations of 30,000 feet. This tactical modification enabled precise delivery of M-69 incendiary bombs while reducing fuel consumption. Each B-29 carried stripped-down armaments with removed gun turrets to accommodate increased bomb loads of 6-7 tons per aircraft.
Number of Aircraft Involved
#| B-29 Fleet Statistics | Numbers |
|---|---|
| Total B-29s deployed | 334 |
| Aircraft reaching target | 279 |
| Formation waves | 3 |
| Average payload per aircraft | 6.8 tons |
| Total incendiary bombs dropped | 1,665 tons |
The operation deployed 334 B-29 Superfortresses from bases on the Mariana Islands, with 279 aircraft successfully reaching their targets over Tokyo. The bombers flew in three coordinated waves, maintaining intervals of 3-4 minutes between aircraft to ensure maximum coverage of the target area. The aircraft formation stretched 40 miles long, creating a continuous stream of destruction over eastern Tokyo's residential districts.
Devastating Impact on Tokyo
#Operation Meetinghouse unleashed unprecedented destruction on Tokyo, creating a firestorm that devastated 15.8 square miles of the city's urban landscape. The Tokyo firebombing generated temperatures reaching 1,800°F in certain areas, transforming the densely populated eastern district into an inferno.
Civilian Casualties and Infrastructure Damage
#The US air raid claimed between 80,000-100,000 civilian lives in a single night, surpassing the death toll of either atomic bombing. Over 1 million residents lost their homes as the flames destroyed 267,000 buildings, including:
- 40 hospitals
- 267 schools
- 300 factories
- 18 shrines
