It's probably much bigger than you think. It has a payload (explosives) of 3850 pounds, which can include multiple 500 pound laser guided bombs and 8 hellfire missiles. It can fly up to 35 hours. As of March 2021, the US Air Force has stated that the unit cost of an MQ-9 Reaper is $56.5 million, though I have read estimates that the true cost is closer to $100 million. See picture below in first comment to see how big it is. It was flown with the transponder off.
