The S-64 Skycrane is an American twin-engine heavy-lift helicopter. It is the civil version of the United States Army's CH-54 Tarhe.
The Aircrane can be fitted with a 2,650-gallon (~10,000 litre) fixed retardant tank to assist in the control of bush fires, and it has proved itself admirably in this role.
S-64 Aircranes have been sold to the Italian and Korean Forest Services for fire suppression and emergency response duties. Those in the Manufacturer Air-Crane fleet are leased worldwide to organizations, companies, and Federal Government agencies for either short-term or longer term use in fire suppression, civil protection, heavy lift construction, and timber harvesting.
