Thermos bomb was the informal name for the AR-4, an air dropped anti-personnel mine used by the Italian Air Force during World War II. Large numbers were used against Malta and in the Middle East. It was named for its superficial appearance to a Thermos bottle, a popular brand of vacuum flask. The bomb was a cylinder 31 centimetres (12 in) long and weighing 3.68 kilograms (8.1 lb). It could be fitted with a very sensitive motion-sensitive fuze that would detonate if any attempt was made to move it. It could be lethal in the open to approximately 35 metres (115 ft). Because of this, unexploded Thermos bombs were normally destroyed where they fell, either by attaching a long piece of string to them and giving it a jerk, or detonating a small explosive charge near them.

La AR-4, fu una bomba aviolanciata antiuomo usata dalla Regia Aeronautica durante la seconda guerra mondiale. Fu largamente usata durante i bombardamenti di Malta e nel teatro del Nordafrica. Dagli inglesi venne denominata "Thermos bomb" per la sua apparente rassomiglianza ad un thermos. La bomba era costituita da un cilindro di 31 cm di lunghezza, di acciaio (corpo) ed alluminio (parte superiore) e dal peso di 3,68 kg. Veniva dotata di una spoletta meccanica della ditta Costruzioni Meccaniche Società Romana che era progettata per non esplodere all'impatto ma era sensibile al movimento/vibrazione. La bomba detonava al minimo movimento e poteva essere letale in un raggio di circa 30 m, con un raggio massimo di 90 m.Другой контент может иметь иную лицензию.
