The great warrior G.I. Joe once said that ‘knowing is half the battle,’ but the Air Force is still using antiquated long-range radar systems from the 1960s to know what threats are approaching on the modern battlefield.
The service plans to fix that with the TPY-4 radar, a ground-based array that has longer range and better coverage than its predecessors and can also pick out smaller objects like unmanned aerial vehicles from the background clutter.
