The United Kingdom has successfully conducted tests of stratospheric balloons aimed at intelligence, surveillance, and reconnaissance (ISR) missions, under the scope of the AETHER Project.

The experiments took place in the United States, in South Dakota, using unmanned balloons capable of operating between 18,000 and 24,000 meters in altitude—well above conventional air traffic. Each balloon carried up to 3 kg of surveillance equipment and remained airborne for over five days, with the balloon constellation providing near-continuous coverage for around a month.

According to the British Ministry of Defence, the system can be launched and operated by a single person even under adverse weather conditions, increasing its potential applications. In addition to military use, the government also sees potential in civil operations such as disaster relief support, remote area monitoring, and meteorological and environmental data collection. Minister Maria Eagle emphasized that the technology represents an advancement in the Armed Forces’ ability to operate in complex environments.

The initiative is the result of a partnership between British and American companies, such as Voltitude, Landguard Systems, and Aerostar, with support from the Defence Equipment and Support (DE&S) agency. Despite current limited capabilities, the UK is already studying more robust versions of these balloons, capable of operating for up to a year and carrying heavier sensors.

The government considers the technology a promising alternative to satellite systems or manned aircraft, which come with higher costs.
