No country has ever bid for both tournaments together, with USA Rugby hoping to bring a World Cup to the Americas for the first time.

A slogan for the bid - "United by Rugby" - has been launched alongside a new website and social media channels.

Research has also been released by bid officials, revealing that 80 per cent of sports fans and 93 per cent of rugby fans would support the United States hosting the men's and women's Rugby World Cups in the near future.

The US was formally accepted as a bid candidate in June following a feasibility study, and 29 cities have put themselves forward as potential hosts.

This includes Atlanta, Boston, Chicago, Dallas, Las Vegas, Los Angeles, Miami, New York, Orlando, San Francisco and Washington D.C, as well as Vancouver in Canada.

"This is a proud moment as we introduce our vision for a Rugby World Cup on American soil," said USA Rugby World Cup bid chair Jim Brown. 

"After working on this for a year now, we are confident in the strength of this bid, the support around us, the cities and stadiums interested in hosting, our country's top-level infrastructure for large-scale sports events and the opportunity the US population of sports fans presents for rugby's growth, both domestically and globally."

The bid has launched as the US men prepare to take on New Zealand in Washington D.C. on Saturday (October 23), in the inaugural 1874 Cup.

Bid leaders are meeting with officials at the White House this week, to discuss the growing popularity of rugby in the US.

"A Rugby World Cup in the United States is a turning point for the game," said USA Rugby chief executive Ross Young.

"An exciting, unique, global sporting event of this scale on American soil for the first time has the potential to bring tried and true rugby fans, new supporters of the sport, US fans and fans from around the world, together through our great game. 

"The Rugby World Cup also presents an incredible opportunity to unite our rugby communities and truly grow the sport from youth programmes to our senior national teams - injecting fan support and financial interest and creating a new generation of American rugby players."

Phaidra Knight, a World Rugby Hall of Fame member and the President of the Women's Sport Foundation, added: "It's clear that current US rugby fans are excited about the potential of hosting Rugby World Cup events, and that fans of other sports are interested in learning more about rugby. 

"These are two phenomenal groups we're excited to bring together through this experience. 

"Additionally, the United States boasts strong women's sports infrastructure and interest, two things that are lacking globally, making us uniquely suited to host the 2029 Rugby World Cup."

World Rugby has set a deadline of January for bidding proposals.

Australia and Russia are among other contenders for the 2027 tournament.
