The DoE operates several UAV's including the Predator. They (or rather the Sandia NL) also developed the Lynx SAR/GMTI which has been mounted on
several UAV's including the MQ-9 which is essentially a larger Predator designed around the Lynx system. The MQ-9 has been deployed to Iraq. There
isn't anything really secretive about the MQ-9, so I'm not sure why you'd hear more in a year or two, though that is when IOC is slated to be
reached.
Whether or not he was pulling your leg, I don't know. But there isn't anything about the story that stands out as particularly 'fishy' to me.
Could have been MQ-9, RQ-1, MQ-1C, or IGNAT all of which are related somewhat (and look somewhat similar) and have ties to Sandia as they continue to
test the Lynx in field conditions.
