During World War II, the skies above London were filled with a distinctive sight: barrage balloons. These floating defences were a common feature of the city's landscape, playing a crucial role in protecting the capital from aerial attack. In this article, we will explore the history and significance of barrage balloons over London.
Introduction to Barrage Balloons
Barrage balloons were large, tethered balloons made of rubber or nylon, filled with hydrogen or helium. They were designed to fly at high altitudes, typically between 2,000 and 5,000 feet, and were used to defend against low-flying enemy aircraft. The balloons were tethered to the ground by a cable, which was attached to a winch system that could raise or lower the balloon as needed.
How Barrage Balloons Worked
The barrage balloons were used to create a barrier against low-flying enemy aircraft, such as bombers or fighter planes. The balloons were positioned in strategic locations, such as near important military installations or population centres. When an enemy plane approached, the balloons would be raised to their maximum height, creating a wall of cables and balloons that the plane would have to navigate through. This made it difficult for the plane to fly low and drop its bombs, forcing it to fly higher and making it more vulnerable to anti-aircraft fire.
- The balloons were also equipped with explosive cables, which would detonate if an enemy plane collided with them.
- The balloons were often used in conjunction with other defences, such as anti-aircraft guns and searchlights.
- The balloons were also used to disrupt enemy aircraft formations, making it harder for them to coordinate their attacks.
Deployment of Barrage Balloons Over London
The first barrage balloons were deployed over London in 1938, and by the start of World War II, there were thousands of them hovering above the city. The balloons were positioned in a series of rings, with the inner ring protecting the city centre and the outer rings protecting the surrounding suburbs. The balloons were operated by the Royal Air Force (RAF) and the British Army, and were an important part of the city's air defence system.
Impact of Barrage Balloons on the War Effort
The barrage balloons played a significant role in the war effort, helping to protect London from enemy bombing raids. The balloons were particularly effective against low-flying aircraft, and are credited with shooting down or damaging numerous enemy planes. The balloons also helped to disrupt enemy aircraft formations, making it harder for them to coordinate their attacks.
- The balloons were also used to protect important military installations, such as airfields and naval bases.
- The balloons helped to boost civilian morale, providing a visible symbol of the city's defences.
Legacy of the Barrage Balloons
Today, the barrage balloons are remembered as an important part of London's wartime history. Visitors to the city can still see remnants of the balloon system, including the winch houses and tethering points. A guided Westminster WWII walking tour is a great way to add context to the history of the barrage balloons, and to learn more about the city's role in the war effort. The balloons may be gone, but their legacy lives on as a testament to the city's resilience and determination during one of the darkest periods in its history.
