Made for the Mission
The UH-72 Lakota is the U.S. Army’s multi-mission helicopter that has proven itself as a key platform for the U.S. Army, Navy, and National Guard in their mission of protecting and serving communities across America. Selected in June 2006 following a rigorous evaluation, it combines operational capability, reliability and affordability, fulfilling all of the Army’s requirements for speed, range, endurance and overall performance. As an in-production helicopter with FAA IFR certification, the UH-72 meets the Army’s commercial off-the-shelf (COTS) acquisition strategy.
The Lakota is based off the the technologically-advanced and operationally-proven H145 helicopter, which is used worldwide for law enforcement, emergency medical transportation, search and rescue, offshore and utility operations, and corporate transportation.
Incorporation of proven and new COTS technologies, combined with the UH-72’s operational capabilities, result in an aircraft that is exceptionally easy and affordable to operate and maintain. Extensive use of new, lightweight manufacturing materials and extensive system modularity simplifies maintenance, reducing lifetime ownership costs and logistics requirements.

Sikorsky S-97 Raider [2015]
Хотя он не находится на вооружении вооруженных сил США, этот список был бы неполным без невероятного Sikorsky S-97 raider. Построенный в соответствии с будущими требованиями армии США к вооруженному воздушному разведчику, Raider включает в себя множество новых технологий, которые позволяют ему преуспеть на поле боя и превзойти своих конкурентов. Наиболее заметной особенностью вертолета является его соосная несущая система, которая обычно используется на российских вертолетах Камова, и толкающий винт. Эта конструкция обеспечивает значительное улучшение по сравнению с обычной конструкцией вертолета, поскольку энергия не тратится впустую, пытаясь противодействовать вращению несущего винта с помощью рулевого винта. Вместо этого соосные несущие винты компенсируют крутящий момент друг друга и обеспечивают необходимую подъемную силу, в то время как толкающий винт обеспечивает переднюю тягу, что дает ему дополнительный толчок, необходимый для полета быстрее, чем его современники.
Рейдер может вместить 6 военнослужащих и нести ракетные капсулы под обрубками крыльев для обеспечения огневой поддержки. Максимальная скорость, которую он может развивать, составляет 444 км / ч, что позволит ему быстро входить и выходить из враждебных районов во время разведывательной или десантной миссии. Этот конкретный вертолет предназначен для спецназа США, поскольку он может быть полезен для быстрой переброски и эвакуации войск. Поступит ли он на самом деле на вооружение вооруженных сил США или нет, остается предметом спекуляций, но этот дизайн определенно будет усовершенствован, и мы увидим похожие вертолеты в ближайшие десятилетия.

UH-72B
In 2020 the Army placed a new order for the latest variant of the Lakota family of aircraft – the UH-72B. Part of the proven H145 family of aircraft, the UH-72B Lakota is the latest iteration of the same commercial, off-the-shelf aircraft that has been the Army’s multi-mission helicopter since the first Lakota contract award in 2006.
The Army is leveraging the benefits of a COTS program by receiving product improvements and enhancements through the evolution of the aircraft, without investing any government money into the research & development of those capabilities.
The UH-72B benefits from numerous product improvements developed during the lifecycle of the commercial aircraft that have increased the power, controls and safety of the Lakota.
A Fenestron shrouded tail rotor comes with a newly designed gearbox that reduces maintenance and enhances safety for ground operations. And a new bearingless, five-bladed rotor increases the aircraft’s load capacity while reducing expense and maintenance.
An enhanced Arriel 2E power plant and dual FADEC generates even more power, and a four-axis autopilot strengthens controls and allows for automated takeoffs. An auxiliary operator’s console allows central control of electro-optical sensors, spotlight and ground data link as part of the security and support mission equipment package.
Pilots benefit from the advanced Airbus Helionix avionics suite, which provides the most innovative and intuitive human-machine interface.
Like its predecessor, the UH-72B is built at an Airbus Helicopters Inc., production facility in Columbus, Mississippi, where the workforce is comprised of more than 30% veterans.
