The Boyd biography by Robert Coram tells the story of the battle between the Fighter Mafia and the Bomber Generals. It also talks about, what I'd at best call regulatory capture. There was an outrageous series of events around procurement of the Bradley fighting vehicle. An excerpt from the craziness that ensued:
"The Bradley was a tragedy waiting to happen. It was packed with ammunition, fuel, and people. The thinnest of aluminum armor surrounded it. So Burton sent the Army’s ballistic research laboratory $500,000 to test the Bradley, and he insisted the testing use real Soviet weapons. The Army agreed. But the first of the “realistic” tests consisted of firing Rumanian-made rockets at the Bradley rather than Soviet-made ones. The Army buried the fact that the Rumanian weapons had warheads far smaller than those used by the Soviets. To further insure that the Bradley appeared impregnable, the Army filled the internal fuel tanks with water rather than with diesel fuel. This guaranteed that even if the underpowered Rumanian warheads penetrated the Bradley’s protective armor, no explosion would result. “What are you going to do about this, Jim?” Boyd asked. “If you let them get away with this, they will try something else.” Burton still believed his job gave him the authority to force the Army to live up to its word. He tried to use persuasion and logic with Army officials, but to no avail. When early tests detected large amounts of toxic gases inside the Bradley, the Army simply stopped measuring the gas. They jammed pigs and sheep inside the Bradley to test the effects of fumes after a direct hit. But the fumes had hardly dissipated before the Army slaughtered the animals without examining them"
Really makes you wonder what procurement is actually about.
I believe this was the basis for the movie The Pentagon Wars which I haven't seen.
