A youth department was formed and the team changed mother clubs, now joining BSC Rehberge, to gain a permanent home ground.

After remaining unbeaten all season in 1987, the team defeated the Badener Greifs in the German Bowl, held in front of a sell-out crowd of 14,800 at Mommsenstadion in Berlin.

[6] The team's first entry in the EFL in 1988 ended in the semi-finals, losing narrowly to the Amsterdam Crusaders but, in 1989, the club returned to success, winning its second German Bowl, again undefeated all season, against the Red Barons Cologne.

[6] The Adler became a dominating team in Germany, achieving a 966-day unbeaten run, which only came to a halt in a league game against the Cologne Crocodiles in 1991.

After playing and losing to the Kiel Baltic Hurricanes, promotion was seemingly missed, but the withdrawal of the Düsseldorf Panther from the GFL opened up a spot in the league for the Adler and the team was back at the highest level for 2002.

In Europe, the Berlin Adler won the EFAF Cup, a second-tier competition, against the Parma Panthers of Italy, the club's first international title.

[10] In 2009, the Adler had another successful season, losing only one league game and advancing to their seventh German Bowl, earning their sixth national title by defeating the Kiel Baltic Hurricanes 28–21.

[10] The 2011 season was not as successful for the club, making a losing appearance in the Eurobowl, finishing only fourth in the league and going out in the quarter-finals of the playoffs to the Schwäbisch Hall Unicorns.

As Berlin lost that game, they found themselves in GFL2 for the following season, failing to stabilize the on-field situation, culminating with yet another relegation to the third tier.
