Woodstock's largest employer is usually reticent about how many of its contracts are military. But in May 2023 the Divisional Vice President at Ametek Rotron told an interviewer: "We only have 20% of our business commercial, 80% is military and defense." This figure is up from the only other figure we have which dates from the 1990s when a Harvard Business School study reported that 60% of Rotron's business was military.
The boss of the Woodstock plant also provided a succinct summary of Rotron's business: "Predominantly the Woodstock plant provides fans and air moving equipment, basically for fighter jets or tanks, or some of the commercial aircraft too, and some of those fans go into electronics cooling equipment for naval applications like submarines, so that is pretty much the scope of work that happens out of my Rotron facilities in Woodstock and San Diego."
