Like in the last two years, quite a lot of software developers in Poland suddenly started doing "R&D", because performing the necessary rituals to convince the tax man that your CRUD app is "research" let you drop your tax rate to 5%.
There's nothing secret about it.
Moreover, many US corporations are effectively encouraged by tax law to go into debt (and always operated under debt), because having a zero effective income means you pay zero taxes. So that's what many companies -- they spend a little bit (or sometime a lot) more than their revenue, and thus report a loss each year (consequently paying zero taxes).
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.
