Conor Daly will return to Andretti Autosport for IndyCar's 2019 season finale at Laguna Seca.
Daly drove for Andretti at the 2019 Indianapolis 500 and finished 10th on his first outing for the IndyCar team.
He then subbed for Max Chilton at Carlin for the oval races after the ex-Formula 1 driver opted against racing on the speedways midseason.
Daly managed 11th and 13th place finishes at Texas and Iowa, but he has not completed a full IndyCar campaign since 2017 when he drove for AJ Foyt Racing.
"I couldn't be more excited to get back to my road course roots and take on Laguna Seca with Andretti Autosport and [primary sponsor] the United States Air Force," said Daly.
"It's been incredible to be a part of the team this year carrying the USAF colours and to represent them at the season finale will be very special.
"I'm very proud of what we've been able to do with the USAF this year on and off the track and I can't wait to get back in the #25 car!"
Andretti, who has committed to a fifth entry for the second time in 2019, said: "We are thrilled to have Conor, as well as the U.S. Air Force, join us again for the season finale in Laguna Seca.
"Conor was a great addition during the month of May, and being able to continue this great partnership with the Air Force at the series season finale is another special opportunity to show our support, and honour the brave men and women serving our nation."
