Beartrap (hauldown device)

A helicopter hauldown and rapid securing device (HHRSD) or beartrap enables the landing and handling of helicopters and unmanned aerial vehicles (UAVs) aboard small ships in poor weather.

The beartrap was developed by the Royal Canadian Navy (RCN) in the 1950s and 1960s, and entered service in 1967. It was quickly adopted by other navies and remains in use.
