The US Navy and its allies employ a range of cutting-edge tactics and technologies to defend against enemy helicopters at sea.

One key method is electronic warfare, which involves jamming the communication and navigation systems of hostile helicopters.

By disrupting their ability to communicate and coordinate attacks, the Navy can neutralize the threat posed by enemy aircraft.

Another crucial technique is the use of advanced missile defense systems, such as the Phalanx Close-In Weapon System (CIWS) and SeaRAM, which are capable of targeting and intercepting incoming missiles and aircraft with remarkable precision.

These systems provide a robust shield against aerial threats and enhance the overall defensive capabilities of Navy and allied ships at sea.

In addition, naval vessels are equipped with long-range surveillance and tracking systems, allowing them to detect and monitor enemy helicopters from afar.

This early warning capability enables the Navy to proactively respond to potential threats and effectively coordinate defensive maneuvers.

Overall, the US Navy and its allies leverage a combination of electronic warfare, missile defense systems, and advanced surveillance technologies to effectively combat enemy helicopters at sea and ensure the safety and security of their naval forces.
