The next team to come out of the City were the Hull Pirates, who achieved a third-place position in the National League in their only season of existence.
Hull was chosen as the base city for the new club with the majority of players from both teams forming into one squad with the exception of some who opted to join the Lincolnshire Bombers.
[2] Warhawks' first ever official season saw them placed in the NFC South 2 along with the Lincolnshire Bombers, Leicester Falcons, Peterborough Saxons, Leeds Bobcats and Sandwell Steelers.
Humber struggled in their opening season, with their best performance coming in a 52–16 home defeat against the Leeds Bobcats.
The Warhawks appointed Lincolnshire Bombers Offensive Coordinator Alex Robson as Head Coach who in turn acquired a wave of experienced players from other sides.
They also notably ran relegated Division One side Staffordshire Surge close only losing 30–26 with the winning margin coming because of Humber failing to convert PAT's.
Robson resigned from the Warhawks at the end of the season in order to start a family, handing back the Head Coach position to Pete Scorah.
After a difficult start to the season going 0–4, the Warhawks spirit wasn’t dampened and the beginning of the season was seen as a good learning curve for the young squad, an interesting test as the 0–4 Knottingley Raiders travelled to Humber, on a very hot July afternoon the Warhawks determination and effort paid off with an 18–8 victory, rookie Brad Wright scoring a brace of receiving touchdowns both thrown by Josh Guthrie in only his second career start.
The 2019 season saw more changes to the Warhawks leadership, Alex Moore being appointed as Head Coach to replace Jerome Cronin.
Again sitting at 0–4 in a season the Warhawks travelled short handed to the Crewe Railroaders, with just 22 players making the trip it was going to be a difficult afternoon, but a defiant Humber outfit pushed Crewe all the way, eventually coming away 20–13 winners, Brad Wright, Jack Storey and Lewis Gaden scoring the touchdowns for the 'Crewe 22'.
After a big victory Humber only had a week to wait, before travelling over the bridge to Lincoln, a strong Lincoln side were rocked when Humber Quarterback Josh Guthrie ran in a touchdown on their first possession and then the Bombers turning the ball over to the Warhawks on their first drive.
