Defense contractors extract money from the government, they are not here to enable space travel, they are here to move money from other people's pockets to their own. Any other actions are purely ancillary. And if they can get the money without delivering any result at all, why, they're fine with that.
This is part of the reason why the new era of firm, fixed price contracts at NASA is so important. And why it's so troubling that NASA is having difficulty transitioning SLS contractors to such contracts for later (Artemis V+) rockets.
