Stealth Aircraft are the future of new-generation warfare.
Operation Neptune Spear
Remember 2nd May 2011? An operation code named Neptune Spear was executed by the United States. In this operation, two Black Hawks MH-60 stealth helicopters were used. No one knows about the secret stealth technology used in the making of those two helicopters.

The Navy Seals were not able to destroy the helicopter completely.
The tail rotor section was partially intact. In one of the papers, it was mentioned that Pakistan gave the Chinese Army access to the crashed helicopter. It is also believed that Chinese officials also collected samples and photographs of the wreckage.
This was the first time in history that a stealth helicopter was used. Till now, in 2021, no country has ever used stealth technology in helicopters except the United States. Read in detail about the interesting helicopters used in the Neptune Spear operation here.
