Ireland internationals Jordi Murphy, Jacob Stockdale and Will Addison are among a number of players who have agreed contract extensions to remain with Ulster.
Murphy and Addison, who have been at Ravenhill since signing from Leinster and Sale Sharks respectively in 2018, have both signed two year extensions to their current contracts.
Stockdale, Sean Reidy and Matty Rea are also set to remain in Belfast as head coach Dan McFarland announced his squad for next season.
McFarland has added plenty of experience to the group with former Ireland international Ian Madigan and former All Blacks scrum-half Alby Matthewson also joining the ranks.
The latter enjoyed a successful stint with Munster as cover for Conor Murray, while former Leinster man Madigan returns to Irish shores after spells in France and England.
McFarland has 41 fully contracted players at his disposal for the new campaign when it eventually kicks off, 39 of whom are Irish-qualified, and believes he has a good balance of youth and experience.
"Our desire to build on the successes of this season to-date is evidenced in our strong investment in talent from the current squad,” he said.
"Although it's an uncertain time for rugby, and all sport, I am confident our selection will stand us in good stead for when we are able to safely start the new season.
"Once again, the chosen line-up of players shines a light on the indigenous talent nurtured through the Academy by Kieran Campbell and his staff – and the role which it, along with the province's clubs and schools, continues to play in securing the future of Ulster Rugby.
"I would also like to take this opportunity to thank the players who are moving on from the squad.
"This includes Clive Ross, who earned 73 caps since joining the province on a development contract in 2014, along with 21-capped Angus Kernohan, and Zack McCall.
"Looking to the future, we look forward to welcoming the new additions to the squad, who are set to bring their own unique skills and talent, as we move towards a time when the 2020/21 season can kick-off."
