When Britain went to war in 1939, its factories faced an acute labour shortage as millions of men were called up for military service. The solution was one of the most remarkable social transformations in British history: the mass mobilisation of women into industrial work.
By 1943, nearly 90% of single women and 80% of married women between 18 and 40 were engaged in war work. They built Spitfires and Lancaster bombers, manufactured shells and bullets, welded ships, operated heavy machinery, and maintained the industrial output that sustained the entire Allied war effort.
Munitions Work
The most dangerous factory work was in munitions — the manufacture of bombs, shells, bullets, and explosives. Women who worked with TNT and other chemicals were nicknamed "canary girls" because the toxic chemicals turned their skin yellow. Despite protective clothing, many suffered long-term health effects. Explosions were an ever-present danger; over 100 women were killed in factory accidents during the war.
Aircraft Production
Women played a crucial role in aircraft production, working at factories across Britain including the famous Supermarine works in Southampton (which built the Spitfire) and the Avro factories in Manchester and Leeds (which produced the Lancaster). They riveted fuselages, installed engines, wired electrical systems, and performed precision engineering work that was vital to keeping the RAF and Fleet Air Arm supplied.
Recognition and Legacy
After the war, most women were expected to return to domestic life, and their industrial contribution was largely forgotten. It was not until decades later that the vital role of wartime factory women began to receive proper recognition. Their story is one of resilience, skill, and quiet heroism.
