I know a few people who work in R&D who are quite good at their activities. They can usually turn around an effective product in at max a year. They usually create a set of underlying patents, this takes maybe a year of reading academic journals and thinking of your physics and me guys, and then you usually have a theory you can put in practice. Apparently, all they need from there is a trip to home depot, one or two things off amazon, and a PCB designed and printed. From there, they can make a wide range of products. One small invention can be used as the underbelly for many, many pieces of technology; everything that comes as a result usually also has one or two applications to research or defense. This means big money. Most real R&D is self sustaining, so long as you have a team that can sell. The hard part of R&D is getting the right people in my mind. I've had this conversation with many people, and it usually helps to ask this: has anyone you have met who works in R&D said they didn't like their job? I've never heard of it. I'm curious to see what you think.
