The satellite includes some small engines that contain a toxic chemical called hydrazine -- which is rocket fuel. But they say they are not large booster engines with substantial amounts of fuel. Us Army doesn't reveal any information about the size of the satellite, but according to an armature satellite watcherJohn Lockers captured video, show it to be about 13 feet to 16.5 feet across. He believes it weighs a maximum of 10,000 pounds.
