Olympians Daniel Wiffen and Danielle Hill are part of Ireland's largest ever European Aquatics Championships team who will head to Paris in August.
Olympic champion Wiffen and European gold medallist Hill will join fellow Olympian Mona McSharry and European champions Ellen Walshe and John Shortt as part of a team of 26 swimmers and one diver.
Hill is aiming to defend her European 50m backstroke title in Paris after her gold medal in Belgrade in 2024.
European short course champions Wiffen, Walshe and Shortt will all attempt to secure long course medals this year.
McSharry will be targeting her first European long course medal with Ards native and European Junior medallist Grace Davison also part of the team.
Jack Kelly is set to make his senior Ireland debut on the European stage following a dominant Irish Open Championships where he secured all three breaststroke titles.
Olympians Darragh Greene, Conor Ferguson and Victoria Catterson also return to the competition with Nathan Wiffen set to compete in the open water event in the River Seine.
Paris Olympian Jake Passmore will be Ireland's only representative in diving.
"To bring an Irish team of this size and quality to the European Aquatics Championships is a significant moment for our programme," said Swim Ireland national performance director Andy Reid.
"We have Olympic and European champions leading the way, athletes looking to convert short course success onto the long course stage, and a strong group of emerging performers gaining valuable championship experience.
"That blend is critical as we continue building towards LA 2028."
