The Seahawk is a twin-engine helicopter. it's used for anti-submarine warfare, search and rescue, drug interdiction, anti-ship warfare, cargo lift, and special operations. The Navy's SH-60B Seahawk is an airborne platform based aboard cruisers, destroyers, and frigates and deploys sonobouys (sonic detectors) and torpedoes in an anti-submarine role. They also extend the range of the ship's radar capabilities.
