Aerial reconnaissance facts for kids
Aerial reconnaissance is a way for the military to gather information from the sky. It uses special reconnaissance aircraft to look at the ground below. This helps armies make maps, find enemy troops, and plan their strategy. It is often called "recce" or "scouting" by soldiers.

History of Aerial Spying
Balloons and Pigeons
Long before airplanes were invented, people used balloons to spy on enemies. After the French Revolution, scientists used a balloon named L'Entreprenant in 1794. This was the first time an aircraft was used for military scouting. It helped the French win battles because they could see what the Austrian army was doing. It also scared the Austrian soldiers to see a balloon watching them.
Later, in the 1860s, people started taking photos from balloons and kites. In the early 1900s, a man named Julius Neubronner even put tiny cameras on pigeons. The birds would fly over an area, and a timer would take a picture.
Inventors also tried putting cameras on rockets. Alfred Nobel made a rocket camera in 1896. However, once airplanes were invented, they became the best tool for the job. The first time an airplane was used for scouting in a war was in 1911 by an Italian pilot in Libya.
World War I: Cameras in the Sky
During the First World War, airplanes became very important for spying. At first, pilots just drew sketches of what they saw. Soon, they started using cameras to take photos of enemy trenches and forts.
A British expert named Frederick Charles Victor Laws found a clever way to use photos. He took pictures with a 60% overlap. When looked at through a special viewer, the photos looked like 3D images. This helped map-makers see the height of hills and buildings.
By 1915, armies were photographing entire trench systems every day. Cameras got better and were built into the floor of the planes. By the end of the war in 1918, both sides took thousands of photos daily to track enemy movements.
World War II: Faster and Higher
High-speed Scout Planes
In World War II, it was dangerous for slow planes to fly over enemy territory. The Royal Air Force (RAF) realized that small, fast planes were safer. They took Spitfire fighter planes and removed the heavy guns and radios. They added extra fuel and cameras instead.
These special Spitfires were painted blue or pink to hide in the sky. They could fly very high (30,000 feet) and very fast (almost 400 mph). Because they were so fast, enemy fighters could not catch them.
The Americans used the Lockheed P-38 Lightning and the North American P-51 Mustang for the same job. The British also used the de Havilland Mosquito. The Mosquito was made of wood and was one of the fastest planes in the war. It could fly so high and fast that it could go almost anywhere to take pictures.
Bombers as Spies
Sometimes, big bomber planes were used for long trips. The American Boeing B-29 Superfortress was a huge bomber that could fly very high. It had a pressurized cabin, so the crew could breathe easily at high altitudes. It carried many large cameras to map cities and locate targets.
The Cold War and Spy Planes
After World War II, the Cold War began. This was a time of tension between the United States and the Soviet Union. Both sides wanted to know what the other was doing.
The US built special "spy planes" that could fly higher than any other aircraft. The Lockheed U-2 was a famous spy plane. It had long wings like a glider and could fly at 70,000 feet. This was so high that most enemy planes and missiles could not reach it.
Later, the US built the Lockheed SR-71 Blackbird. It was the fastest plane ever made. It could fly three times the speed of sound. If a missile was fired at it, the pilot simply sped up to outrun it.
Satellites in space also began taking photos. These spy satellites could take pictures of the whole world without entering anyone's airspace.
Modern Drones and Technology
Today, militaries use unmanned aerial vehicles (UAVs), also known as drones. These are planes with no pilot inside. They are controlled by a person on the ground or fly by computer.
Some drones, like the RQ-4 Global Hawk, are very large and can stay in the air for a long time. Others are small enough to be carried in a backpack. Drones have cameras that send live video to soldiers. This lets them see what is happening in real-time without risking a pilot's life.
How It Works
Miniature UAVs
Small drones are very useful for soldiers on the battlefield. They are cheap and easy to carry. A soldier can launch a small drone to look over a hill or around a building.
Some examples of small drones are:
- AeroVironment Wasp III (looks like a small airplane)
- Aeryon Scout (looks like a small helicopter)
- EMT Aladin (made in Germany)
These drones use tiny cameras and electronics. They allow small groups of soldiers to have their own "eye in the sky."
Camera Pods
Fast fighter jets can also do reconnaissance. Instead of building a special spy plane, engineers attach a "pod" to a normal fighter jet. This pod contains cameras and sensors.
For example, the F-14 Tomcat used a system called TARPS to take photos. This saves money because the air force does not need to buy a separate type of plane just for spying.
