2015
The Pittsburgh Thunderbirds finished 2nd in the Midwest division with a 12–2 record, behind the Madison Radicals who finished 13–1. The Madison Radicals lone loss was to the Thunderbirds on May 2, 2015 at Founder's Field in Pittsburgh.

On June 12, 2015, the Thunderbirds were featured on ESPN3's game of the week against the Chicago Wildfire, dropping the contest 19–16 for their 2nd loss of the 2015 season.

Due to scheduling conflicts, the Midwest playoffs had to be played on the same day, July 25, 2015. The #3 seed Chicago Wildfire met the #2 seeded Thunderbirds at a neutral site outside of Madison, Wisconsin at 4:00PM local time. In overtime, Max Thorne threw the go-ahead goal to Aaron Watson to secure the 24–23 victory.

3 hours later, the Thunderbirds went on to face the #1 seeded Madison Radicals at Breese Stevens Field in Madison, Wisconsin. The Thunderbirds would go on to lose the Midwest Championship, 24–21 after Tyler DeGirolamo exited the game with a recurring leg injury.

2016-2019
The Thunderbirds finished the 2016 season with a 10-4 record, second in the Midwest Division behind the Madison Radicals. In the divisional playoffs, they defeated the Minnesota Wind Chill 20-18 before falling the Radicals in the Division Finals by a score of 20-16.

The Thunderbirds qualified for their third consecutive playoff appearance with a 7-4, once again defeating the Minnesota Wind Chill in the opening round and losing to the Madison Radicals in the Division Finals.

On November 13, 2017, Thunderbirds' player Pat Hammonds was announced as the new head coach, succeeding David Hogan.

The 2018 season saw Pittsburgh post its first losing season in franchise history, finishing in 5th place in the Midwest Division with a 4-10 record.

Pittsburgh saw a significant improvement in 2019, finishing with an 8-4 record and returning to the playoffs as the second-place team in the Midwest Division.

On June 8, the AUDL hosted its first All-Star Game at Breese Stevens Field in Madison. Pittsburgh cutter Max Sheppard, the sole Thunderbirds player selected for the All-Star Game, was named the game's Most Valuable Player.

In the opening round of the 2019 playoffs, the Thunderbirds defeated the Chicago Wildfire 21-20 to advance to their fourth Midwest Finals appearance in five seasons, where they lost to the Indianapolis AlleyCats 23-17.

2020's
Following the 2019 season, the AUDL announced a realignment of its divisions, with the Thunderbirds moving from the Midwest Division (now known as the Central Division) to the newly-formed Atlantic Division.

Due to the Covid-19 Pandemic, the 2020 season was initially postponed before being officially cancelled on June 24, 2020.

The 2021 season would be the Thunderbirds' worst to date, finishing last in the Atlantic Division with a 1-11 record. Only the Detroit Mechanix (0-12) would finish the season with a worse record. After the 2021 season, the AUDL went back to its prior 4-division format, and the Thunderbirds returned to the Central Division.

Prior to the start of the 2022 season, the Thunderbirds announced a partnership with the Pittsburgh Riverhounds SC of the USL Championship. The deal included a home game against the Madison Radicals to be played at Highmark Stadium, a cross-promotion between the two teams, team-specific ticket discount offers, and halftime exhibition show by the Thunderbirds at the Riverhounds' May 14th home game against El Paso Locomotive FC.

Philadelphia Phoenix
The Pittsburgh Thunderbirds and Philadelphia Phoenix first met during the 2018 season, with the Phoenix winning 30-18. Although the two teams have played in different divisions for much of their history, a rivalry between them was natural due to being the only teams from the Commonwealth of Pennsylvania, as well as long-standing rivalries between the cities baseball, football, and hockey teams. The two organizations created the Commonwealth Cup trophy to be awarded to the winner of each matchup. .

Stadium
Prior to the start of the 2023 season, it was announced that the Thunderbirds would begin playing their home games at Highmark Stadium as part of an expanded partnership between the team and Pittsburgh Riverhounds SC, the stadium's primary tenant. Previously, the Thunderbirds played their home games at Founders Field in Cheswick, and J.C. Stone Field in Pittsburgh's North park complex.
