Sikorsky SH-60 Ship-borne Helicopter (? Sikorski? SH-60？ Shipborne? Helicopter (nickname: Seahawk, Chinese: Seahawk) is a multi-mission helicopter developed by Sikorsky Aircraft Company in the 1970s on the basis of Sikorsky S-70 helicopter and UH-60 general helicopter.
SH-60 Seahawk can be deployed on naval vessels such as aircraft carriers, destroyers, frigates and amphibious ships. , with an aircraft operation deck, performs anti-submarine warfare (ASW), anti-surface warfare (ASAW), naval special operations (New South Wales), search and rescue (SAR), combat search and rescue (CSAR), vertical replenishment (VERTREP) and medical evacuation (MEDEVAC).
In addition to being used by the US Navy, SH-60 Seahawk is also exported to more than ten countries and regions such as Japan, Australia, Greece, China and Taiwan Province Province. The total number of helicopters manufactured exceeds 1000, making it one of the most widely used naval helicopters in the world.
