Boeing has secured a contract from the US Air Force (USAF) to continue maintenance of C-32A and C-40BC executive aircraft.
Under the terms of a $319m contract, the company will continue to maintain and support the C-32A and C-40BC aircraft for another seven years.
Based on the Boeing 757 and 737 passenger planes, the C-32A and C-40BC are used by the USAF to transport the vice president, cabinet members and military commanders among others.
Boeing executive transport services and support programme director Jerry Dunmire said: "The Air Force can rely on Boeing anytime, anywhere in the world.
"We take great pride in keeping these essential aircraft ready and updated with the latest technologies."
Aimed at transporting military passengers, the C-32 is more fuel efficient than its predecessor, VC-137, as it can travel twice the distance with the same amount of fuel.
The Boeing C-40B has been built to replace the ageing fleet of C-137 aircraft for US combatant commanders, while the C-40C replaces C-22s and is operated by the Air National Guard and National Guard Bureau to airlift personnel.
Boeing said that it has supported the aircraft since its first delivery in 1998 and 2001.
In April this year, Boeing was contracted to provide 20 joint direct attack munitions (JDAM) tailkits for the USAF.
Under the $325m contract, the company will supply a total of 15,000 tailkits to the USAF.
