In 2021 the team challenged for the 36th America's Cup in Auckland, New Zealand, representing the Royal Yacht Squadron.

His team competed in the AC45 class for the remaining races of the 2011–13 America's Cup World Series to develop experience and generate interest from sponsors.

[2] In January 2014, Ainslie began the process of raising £100M to fund the team, as well as development of racing yachts which was projected to take 30% of the budget.

[6] Having reviewed a number of sites, the project put forward plans to develop an operational building at Camber Dock, as part of the wider redevelopment of Portsmouth Harbour.

[7] On 18 June, Portsmouth Council approved plans for the £12M main operations building, which Ainslie confirmed would be built subject to £8M of requested UK Government-backed development funding.

[9] The operational building is also where the boats are designed and manufactured, and contains administration and full crew development facilities.

[10] In September 2018 it was announced[12] that sailing clothing brand Henri Lloyd would continue its long partnership with Sir Ben by supplying the kit for Ineos Team UK in the pursuit of the 36th challenge of the America's Cup in 2021.

The team had excellent performance in two events in San Francisco but slipped to a surprise defeat in Naples in April 2013.

[13] In August 2013, the competition jury received a report from Oracle Team USA that their boat and others they had loaned had unauthorised modifications.

Following the announcement that alongside the 35th Americas Cup would be held the Red Bull Youth Americas Cup, Land Rover BAR launched the Land Rover BAR Academy in January 2016, with over 150 young British sailors under the age of 24 applying to be part of the team.

The squad trained and competed on a GC32 Class catamaran in the Extreme Sailing Series in 2016 and 2017, under the expert guidance of the team's senior sailors and coaches.

Following the collapse of the Extreme Sailing Series at the end of 2018, the team began using their two GC32s for two boat training in preparation for their 36th America's Cup campaign.

[24] In March 2020, however, due to the COVID-19 global pandemic the team made the decision to withdraw all sailing operations from Sardinia and return to the UK.

Following a disappointing performance in the Auckland ACWS event in December 2020, the team spent the following three weeks making modifications to their boat Britannia ahead of the start of the Prada Cup qualifying series.

The Prada Cup Finals were held in predominantly light wind (8-14 knots), with Luna Rossa showing great improvement in boat handling, winning the first 5 races consecutively.

It was contested from 12 October 2024 as a first-to-seven-wins match-race series in Barcelona, Catalonia, Spain, between Taihoro, representing the defender, the Royal New Zealand Yacht Squadron;[30] and Britannia, representing the Royal Yacht Squadron of the United Kingdom, which won the Louis Vuitton Challenger Selections Series, also in Barcelona, on 4 October 2024.
