Olympic medallists Jack Laugher, Dan Goodfellow and Tom Daley have been named in a 15-strong British squad who will travel to Tokyo in April for the FINA Diving World Cup.
The competition will take place in the same aquatics centre as this summer's Games and a handful of Olympic qualification slots remain available.
A successful World Aquatics Championship in 2019 secured Great Britain a pair of places in most disciplines but single spots are up for grabs in the women's 3m springboard and 3m synchro, in addition to the women's 10m synchro and platform events.
The squad contains a blend of experience and youth, with 17-year-old Andrea Spendolini-Sirieix – who became British champion last year – competing in the women's 10m platform alongside 2015 European silver medallist Robyn Birch.
One Olympic spot is available in the men's 3m springboard, a competition which will include Goodfellow and British champion James Heatly, while European and Commonwealth champion Grace Reid will be in action alongside Katherine Torrance in the women's 3m synchro.
Reid, Daley and Laugher will focus on synchro events alongside their respective partners, with the latter looking to add to his silver and bronze from the 2018 World Cup as he returns to competitive action for the first time in over a year.
The event runs from April 18-23 and British Diving's Performance Director, Alexei Evangulov, said: "I'm delighted to name such a strong British team for the World Cup.
"This is such a key competition for us, with qualification still up for grabs in certain events and having been out of competition for so long. I am, however, very confident in our preparations.
"Last year, I was so impressed with how hard our divers worked when they were out of the water and they came back in better shape than me and my coaches could have imagined.
"It will also be very important to experience the venue in Japan, and how the organisers manage COVID protocols at what is usually an extremely busy event.
"This will be especially important during the warm up sessions, and will be an extremely valuable experience for our divers.
"For now, though, we must really focus on being in our best shape for the World Cup, European Championships and Olympic Games."
