Background

The US Army's LHX program began in the early 1980s, proposing two helicopter designs with a high percentage of commonality of dynamic components. One was a light utility version ("LHX-U") for assault and tactical movement of troops and supplies, the other was a light scout/attack version ("LHX-SCAT") to complement the growing development of the AH-64 Apache
AH-64 Apache
The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew. The Apache was developed as Model 77 by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the...

. As the program was developed, the light utility version was dropped and focus was placed on the light attack reconnaissance version, which eventually became the RAH-66 Comanche
RAH-66 Comanche
The Boeing-Sikorsky RAH-66 Comanche was an advanced five-blade armed reconnaissance and attack helicopter designed for the United States Army. The RAH-66 program was canceled in 2004, before mass production began, after nearly $7 billion was spent on the program.During the early 1980s, the U.S...

 and the US Army made the decision to terminate the RAH-66 program. As part of the termination, the Army was allowed to keep the future years' funding programmed for the Comanche. To replace the capability that the Comanche was supposed to offer, the Army planned several programs, including three new aircraft. The Army Staff decided that these three aircraft, the Armed Reconnaissance Helicopter (ARH), the Light Utility Helicopter (LUH), and the Future Cargo Aircraft (FCA) (later renamed Joint Cargo Aircraft, or JCA), were to be existing, in-production commercial aircraft modified for Army service.

LUH Program and UH-145

The LUH program was initiated in early 2004, with an initial stated requirement for 322 helicopters to conduct Homeland Security, administrative, logistic, Medical Evacuation (MEDEVAC) and support of the Army Test and Training Centers missions. The LUH contract was released in late July 2005. At least five proposals were received. The competitors included the Bell 210 and Bell 412

 (EADS NA) marketed the UH-145 variant of the EC 145 for the program.

On 30 June 2006, the Army announced that the EADS NA entry had won the competition for the LUH contract, the value for which was estimated as being worth over $3 billion. In August, the UH-145 airframe was officially designated the UH-72A by the Department of Defense. The UH-145 award was confirmed in October 2006 following protests from losing bidders.

Despite the impact of the four-month delay associated with the protests, EADS NA was still able to deliver the first UH-72 on time during a ceremony in December, at which time the name Lakota was also formally announced for the type, in line with the Army's long-standing tradition of giving its helicopters Native American names. The LUH marked EADS NA's largest DoD contract to date, and added to existing programs including the U.S. Coast Guard's

On 10 July 2007, the Training and Doctrine Command (TRADOC) Flight Detachment at Fort Eustis, Virginia became the second Army unit fielded with the UH-72A.

A report published in August 2007, by the Operational Test and Evaluation Directorate (DOT&E) noted that, although the Lakota "is effective in the performance of light utility missions" it was prone to overheating during operations in the desert conditions of Fort Irwin, when not equipped with air conditioning systems. In response, vents were added in the doors to increase cabin air flow; air conditioning has been installed on some Medical and VIP versions also added air conditioning units for crew comfort.
