FBI Probes 'Possible Energetic Materials' in Package at MacDill Air Force Base

The FBI’s Tampa office says a suspicious package discovered Monday outside the visitor center gate at MacDill Air Force Base in Tampa contained 'possible energetic materials,' a term that can encompass explosives, fuels or propellants, and that laboratory analysis and the investigation are ongoing. MacDill, which hosts U.S. Central Command and is already on heightened alert due to the Iran war, briefly issued a shelter‑in‑place order Wednesday after a separate threat before lifting it about two hours later. Base officials say they are operating under Force Protection Condition Charlie, the second‑highest U.S. military security level, and are implementing additional security measures they will not detail publicly. Personnel have been urged to remain vigilant, follow security‑forces directions and report suspicious activity, underscoring concern about potential threats to a central hub for U.S. Middle East operations. The incident comes days after a KC‑135 refueling tanker crash supporting operations against Iran killed six crew members, three tied to MacDill’s 6th Air Refueling Wing, adding to scrutiny of the base’s operational tempo and risk environment.
