Wales face South Africa in an away fixture at Twickenham Stadium on 22 June before heading for Australia on 26 June to play two Test matches against the Wallabies and a fixture against the Queensland Reds.
An updated squad of 34 players who will travel to Australia will be confirmed following the Springboks encounter.
Four uncapped players are selected among the 22 forwards and 15 backs named today: Cardiff Rugby’s Ellis Bevan (scrum half) and Jacob Beetham (full back), as well as wingers Keelan Giles (Ospreys) and Josh Hathaway (Gloucester Rugby).
Ben Carter, Dewi Lake, Jac Morgan, Taine Plumtree and Christ Tshiunza return for Wales having missed the Guinness Six Nations due to injury.
There are also recalls for hooker Sam Parry, tighthead prop Henry Thomas, second rows Cory Hill and Matthew Screech and back-three Liam Williams, in a Wales squad that has an average age of 25.
A decision has been taken to give Josh Adams, Ryan Elias and Will Rowlands a break this summer, so they have not been selected in the squad.
Gatland said: “We’ve selected a bigger squad because we don’t have the English club-based players available for the South Africa match. So we will be reducing the squad from 36 to 34 players for Australia.
“I think everyone appreciates and realises we’re building towards 2027. There were moments during the Six Nations where we played some really good rugby and put the opposition teams under some pressure, but we probably weren’t accurate enough.
“It’s about playing for longer periods, putting halves together and putting an 80-minute performance together which ultimately gives you confidence and gives you that opportunity to win games.
“We need to build on that. We need to keep working hard. We’ve got some experience to come back into the squad and some exciting players which is good.
“The big focus for us is about our game management and to get better with that. But we also want to improve our collision dominance whether that’s attack or defence and create some more depth and competition within the squad.”
Regarding the captaincy, Gatland added: “When the squad comes in we will look at a leadership group that is going to be important for us going forward.
“Then we’ll probably be looking to name a captain for the South Africa game and then name a captain for the tour”.
