A U.S. Air Force EC-130H Compass Call arrived at Luis Muñoz Marín International Airport in San Juan, Puerto Rico, the day before yesterday, December 20, according to an X post by @Arr3ch0 published over the past 90 minutes ending at 12:15 p.m. UTC on December 22. The aircraft serves as an airborne tactical weapons system to disrupt enemy command and control communications. The EC-130H Compass Call is a heavily modified version of the C-130 Hercules airframe costing approximately $165 million, as detailed in @Arr3ch0's post with supporting images. This deployment aligns with earlier reports of the aircraft's arrival cited by Global_Mil_Info referencing aviation spotter pinchito.avgeek on December 22. The Compass Call arrival precedes a U.S. Air Force C-17A Globemaster III deployment from Whidbey Island Naval Air Station to Ceiba, Puerto Rico, tracked by @Flightwatcher1 between 8:16 a.m. and 10:46 a.m. UTC on December 22.
