There's a bit of double-counting here too. DARPA doesn't actually do much (any?) research on its own. Its role is to award contracts to "performers" that actually run the experiments, train the models, build the devices, etc. In other words, a big chunk of (e.g.,) Teledyne's R&D budget is actually the same money as DARPA's R&D budget.
