ill take a wild guess that is has some type of phased array multispectral antenna for collecting signal intelligence over wide bands of the em spectrum, and pinpoint the locations of the transmissions. shit like that is very expensive. they also have a gigapixel camera arrays, and need all the electronics to process the em spectrum and their video feed data. then they need all the support electronics, power and control, and the engine. plus some significant profit to the procurement and production of said vehicle. remember these specialized electronics aren't like your gpu which get massed produced for millions of customers, they probably only make several thousand at a time which considerably increases costs. totalitarian espionage is expensive.
