The FBI has launched an investigation into security vulnerabilities on the Boeing 747-800 donated by Qatar to the US President, according to reports.

The probe focuses on the aircraft's lack of missile defense systems, a gap that has drawn scrutiny after President Donald Trump recently used the jet for international travel.

Trump addressed the issue on Sunday, stating that the aircraft would soon be "upgraded to the maximum." He confirmed that the Boeing 747, which currently serves as an Air Force One variant, will be sent for extensive security modifications.

The announcement comes amid growing questions about the readiness of the donated plane for presidential duties.

The investigation highlights the complexities of integrating foreign-donated assets into US presidential security protocols.

While the aircraft provides a luxury alternative to the standard VC-25 fleet, the absence of standard defensive countermeasures raises operational risks.
