That US drone the Iranians shot down

The TV news shows a picture of a sizable airplane shaped drone,single engined,  jet powered.  I didn't catch the name.  Too big to be a Predator.  They say it has the wing span of a 737 jet liner, and a price, $180 million, that would buy us a new 737.  Seems a bit much for a single engine sub sonic aircraft, with no cockpit, no pressurization, no manual flight controls, no cockpit windows.  Granted such a beast needs an autopilot fancier than most, some high powered camera's and a telemetry transmitter to send the photos back to base.  But I would expect a photo recon drone to cost less than an airliner.  A lot less.
