The UK and US collaboration in space domain awareness (SDA) reflects their enduring military alliance, marked by a memorandum of understanding that streamlines military space strategies and joint operations, including vital information exchange, Space Domain Awareness - How the UK and US Cooperate. This partnership is further strengthened by the UK’s new joint task force-space defense commercial operations cell, which collaborates with its US counterpart to bolster orbital surveillance, thus enhancing the monitoring of satellites and hazardous space debris.
