US military helicopters are integral to a wide range of missions, serving critical roles in combat support, troop transport, logistics, medical evacuation, and special operations. Key models include the UH-60 Black Hawk, renowned for its heavy-lift capability and versatility in roles like battlefield support and air assault. The AH-64 Apache stands out as the primary attack helicopter, equipped with advanced weaponry for engaging ground and naval targets with precision. The CH-47 Chinook excels in heavy-lift transport, capable of carrying substantial cargo and personnel for logistical support and emergency operations. The UH-1 Huey, famous for its historical significance, remains a stalwart in transport, medevac, and reconnaissance missions. Lastly, the MV-22 Osprey combines vertical takeoff and landing capability with fixed-wing flight, serving rapid deployment and specialized missions. These helicopters collectively enhance US military readiness and effectiveness across diverse operational scenarios.
I've got a Popular Science magazine from the early '50's, showing something similar. It's been a long desired thing, airplane speed and rotary wing landing performance.
very good for that encouragement and spirit of improvement, America has to be great again, it cannot be that the Chinese and the Russians are far above in terms of science, technology and academia, than the Americans
Americas freedom is not cheap, there is a cost to it. In money, are technology is the best in the world. A cost of lives defending are freedoms. The worst thing a person can do, is betray their country. That gave us the freedom , and opportunity in this country.

Why not create how to create heavy wind to wipe out .From front sides and downside and above the helicopter or upper part and back side . This is silly common sense .
