The second row joined Wasps Academy in the 2009 season, made his Premiership debut against Leicester Tigers two years later and has since gone on to make 117 appearances in black and gold.
During that time, he has played a pivotal role in the club’s steady progress up the Aviva Premiership table, climbing from 11th to reach the play-offs in 2016 and the Final in 2017.
Speaking about his contract extension, Launchbury said: “I am delighted to sign a new contract to stay at Wasps. It’s a place my family and I have come to call home over the past seven years and I’m really pleased to sign on again for a bit longer at the club, as we work hard to fulfil the ambitions we have as a squad.
“Over the past few weeks, it has been great to see a number of players signing new contracts, enabling the club to retain quality players in what is already a fantastic squad. That reflects the belief we have in Dai [Young] and in our squad, that together we can build on the progress we’ve made over the past few seasons and take our game to the next level. I really want to play my part in that moving forward.
“We’ve had our disappointments, but I feel over the past few years we’ve really shown our potential on both the European and domestic scene. I truly believe we can fulfil that potential over the coming years and really want to be part of that.”
