The team will continue to operate out of the Silverstone-based factory that it has occupied for the last three decades, since it entered the sport as Jordan Grand Prix, with new facilities at the same location due to open in mid-2022.
The AMR21, which features a traditional green livery with shades of pink, was unveiled by the team on Wednesday afternoon.
The launch featured cameo appearances from star-studded names, including Tom Brady and actor Daniel Craig, who plays James Bond in the franchise affiliated with Aston Martin.
The car make its track debut during a shakedown at Silverstone on Thursday.
Aston Martin, which has maintained close ties with Mercedes, has recruited four-time World Champion Sebastian Vettel and retained Lance Stroll.
Vettel arrives off the back of a subdued final season with Ferrari, placing 13th in the standings, having previously won 52 grands prix in his career, the third-most in history.
Stroll joined Formula 1 with Williams in 2017, moving to Racing Point in 2019, and last season scored two podiums, as well as his maiden pole position, classifying 11th overall.
The team finished fourth in the Constructors’ Championship and scored a win in Bahrain, courtesy of Sergio Perez, who will drive for Red Bull in 2021.
