UH-60 Blackhawk

UH-60 Blackhawk helicopters are the most common in the U.S. Army; they are one clan of a large family of H-60 series helicopters used by all services except the U.S. Marine Corps]. They replaced the [[UH-1, officially the "Iroquois" but invariably known as the "Huey", iconic of the Vietnam War. Blackhawks are a light to medium capacity design used for troop transport, aeromedical evacuation, command and control, and various specialized tasks. Depending on the mission, they may be armed helicopters, but dedicated attack helicopter variants are not used in conventional Army operations.

In the troop transport role, it can carry a 11-man infantry squad, or externally lift a load of the size of a light 105mm howitzer; the CH-47 Chinook medium helicopter carries larger artillery.

Blackhawks have evolved considerably since the original version built for the U.S. Army.

First generation
As would be expected, the first model was the "A", although there soon were a number of derivatives. There were a number of A-model utility transports, many exported, and the EH-60C SIGINT platform with the "Quickfix" signals intelligence (SIGINT) and electronic warfare (EW) emitter location and targeting system.

Second generation Army
The underpowered A models first became the base UH-60L, with an improved engine and transmission.

Aeroedical evacuation versions were the UH-60Q, and the improved HH-60L.

Generation 2.5
A and L models were moved to M level, with structural improvements, digital cockpit, and an engine upgrade.

The HH-60M was the improved medevac version and the UH-60I had an Army Airborne *Command and Control System.

EW and SIGINT have moved to unmanned aerial vehicle platforms.
