I am not sure that these decisions are not historically the American way of preparing for war. If you think about it when America entered WW1 it was almost completely reliant on Europe for a significant amount of its' combat technology. After the war there was what is tantamount to a technology revolution, especially in aviation. Curtiss, Bell, Northrup, Lockheed,, etc., while not exactly venture capitalist, they certainly were independent thinkers. Many backed by what we call 'Venture Capitalist.' The United States in the 1920s and 30s was certainly as aggressive as any country in the rapid exploitation of technologies, while Ford, Chevy, Dodge and many other Capitalist enjoyed funding profiles to make large factories and train more people to build things on a huge scale. The United States Army Air Corps had a multitude of varied aircraft types that it tested. To me that it was, by today's parlance; "try-fly-decide."
So the 21st Century technologist/industrialist are not drastically different than their predecessors of a century ago if you ask me.
Remember that the Army is trying to move away from vendor lock, so that other than the core airframe, everything else can be changed out as desired, or required. We will see how that works. Sometimes I think that this notion of Modular Open Systems Architecture (MOSA), that the FLRAA program is the poster child for, is the real reason it has been safe to date. We will see.
@Scott Kenny - sometimes "the juice isn't worth the squeeze". The program was already years behind schedule and significantly above the original funding line. As the U.S. Army now has a decrement funding profile, an anemic program like this was easy pickings.
