The Globe and Mail reports in its Saturday edition that Boeing said Sunday it remains on track to deliver two new Air Force One jets in 2028, but meeting that target will require additional spending on a program already years behind schedule and billions of dollars over budget. A Reuters dispatch to The Globe says that Boeing was awarded a $3.9-billion (U.S.) contract in 2018 to build the aircraft, though costs have since ballooned to more than $5-billion (U.S.). The aircraft are intended to replace the current Air Force One planes, which entered service in 1990. "We're on track for 2028," Steve Parker, chief executive officer of Defense, Space & Security, told reporters ahead of the Farnborough Airshow in England. "I do expect to see some cost growth there as we come through and we finish off the wiring and the structures, as well as finishing up our own certifications." In May, 2025, the United States accepted a luxury Boeing 747 from Qatar for use as a temporary presidential aircraft. The jet has since entered service as a bridge aircraft. Security concerns led President Donald Trump to forgo flying the Qatari jet home from Turkey, opting instead to return aboard an older Air Force One.
