It can drop water on a target with pinpoint accuracy, which is critical for controlling fires in remote or hard-to-reach areas.
The Development of S64 Helicopter
The S64 helicopter, commonly referred to as the Sikorsky Skycrane, was developed by Sikorsky Aircraft Corporation. Its development began in 1958, and it was primarily designed to carry heavy cargo and equipment. However, over the years, the helicopter has been upgraded and modified to perform various tasks.
The First Prototypes and Early Service
The development of the S64 helicopter started in 1958, and the first prototype, known as the YCH-54A Tarhe, was completed in May 1962. The Tarhe was tested in various areas, including lifting heavy loads and firefighting. The helicopter showed great promise, and soon, the US Army ordered 54 more helicopters. The Army eventually used the Tarhe for various missions, including artillery emplacement, missile transport, and logistical support.
Upgrades and Modifications
Over the years, the S64 helicopter underwent several upgrades and modifications to improve its performance. In 1992, Sikorsky introduced the S-64E model, which had a more powerful engine and other enhancements that increased lift capability. The helicopter could now carry a maximum external payload of 20,000 pounds.
In addition to the new engine, the S-64E model had an extended fuel tank, a new fire-fighting tank, and other modifications that made it more versatile. The helicopter could now perform a range of tasks, including firefighting, construction, and transport of heavy cargo.
