NGAD - INSANE Engineering of US 6th Generation Fighter Jet!
the NGAD fighter maximizes its stealth features by taking an overall triangular shape, internally holding its payload, and having no distinct tail section, also known as vertical stabilizers. It is the first fighter in history to be unveiled with such a revolutionary design. Vertical stabilizers had always been required to keep an aircraft airborne until the concept of Active Flow Control came to life in the B-2 Spirit.

Active Flow Control uses computer brains onboard to constantly adjust the flow around the aircraft to keep it airborne, similar to how birds fly. The result of this on an aircraft is top-level stealth and, well, a not-so-wallet-friendly cost. This, to an extent, justifies why the B-2 costs $2 billion and why Congress has budgeted over $10 billion for the NGAD in less than a decade.
