With approximately 31,000 helicopters in the global fleet, there are aircraft for almost every task and mission you can think of. But out of that massive number is a true standout — the Sikorsky UH-60 Black Hawk. Arguably one of the most famous — and reliable — aircraft around, the UH-60 is a general-purpose helicopter named after the Sauk warrior and leader Black Hawk. But why has the UH-60 remained an integral part of fleets worldwide? Here’s a look at this versatile helicopter’s nearly 50-year history and upgrades.


What is the UH-60?
The UH-60 Black Hawk is a four-blade, twin-engine, medium-lift utility helicopter originally developed and produced by Sikorsky Corporation. First designed in 1972 for the US Army, the Black Hawk was selected to be mass-produced in 1976 after a competition with the Boeing Vertol YUH-61. Shortly thereafter, the UH-60 officially entered service with the U.S. Army in 1979.


What is the UH-60 designed for?
Initially, the U.S. Army’s goal was for the UH-60 to replace the Bell UH-1 Iroquois and become the Army’s new tactical transport helicopter, which it did. And since it entered the U.S. service, the UH-60 has been developed for use in combat spaces worldwide. From the U.S. Navy and Air Force to the Coast Guard, the Black Hawk performs various tasks, including tactical personnel transportation, electronic warfare, and air rescue.

The UH-60 is a powerhouse of a helicopter powered by two General Electric T700 turboshaft engines. It has a long, low-profile shape allows it to be transported aboard a C-130 Hercules. Equipped with advanced avionics systems such as GPS to enhance field survivability and performance, the UH-60 can carry out an air raid mission with 11 soldiers and equipment, transporting supplies with 1170 kg (2600 lbs) of cargo, and much more.

With its impressive build and versatile equipment, the UH-60 comes in many models to fulfill different roles, from utility to special military performance to VIP missions. For example, the U.S. Army variants can be fitted with stub wings to carry additional fuel tanks or weapons, increasing range and performance. A VIP version is known as the VH-60N is used to transport important government officials, with a call sign of “Marine One” when transporting the President of the United States.


How has the UH-60 been upgraded?
Since 1979, the UH-60 has been modified for various new missions and roles. After entering service, an EH-60 variant was developed to conduct electronic warfare. Special operations aviation developed the MH-60 variant shortly thereafter to support its missions. But with weight increases from the addition of equipment, new improvements had to be made, which led to an improved UH-60L in 1987. This new model incorporated all the modifications to the UH-60A fleet as standard design features, with more power, lifting capability, upgraded T700-GE-701C engines, and an improved gearbox.

To extend the service life of the UH-60 design into the 2020s, development began on the next improved variant, the UH-60M, in 2001. This upgrade incorporates upgraded T700-GE-701D engines, improved rotor blades, state-of-the-art electronic instrumentation, flight controls, and aircraft navigation control.

While the UH-60 is as reliable and tough as they come, a new Sikorsky-Boeing aircraft is in development to replace it. As it’s being called, the Defiant X is one of two candidates being developed to replace the almost 50-year-old UH-60 Black Hawk. And with the ability to fly twice as fast as the Black Hawk and improved range and survivability, it’s certainly a contender.
