South Africa have put faith in experience as the target a first ever defence the World Cup.
Head coach Peter de Villiers has selected eighteen 2007 World Cup winners and the core of the Test squad that faced the Lions in 2008.
Bath-bound Francois Louw, who has not pulled on the green and gold for more than a year is a surprise inclusion following the loss of Juan Smith to injury. Ulster captain Johan Muller has also been recalled.
"The squad has a backbone of proven title-winning ability and experience as well as a strong component of new stars," said De Villiers.
"Injury has denied us one or two players who could have been very important to us, but I am very happy with the squad we have picked. We have good coverage for every position and front line players who have shown over the past half dozen seasons that they know how to win big games.
"This squad has the experience and ability to make a strong challenge for the title, but we know it will be very difficult.
"It has been a tough season to date and we have had some challenges with the amount of rugby the players have had to play, but I’m very happy with the squad. We are on target with the off-field plans we set in place before the season started."
The Springboks kick-off their title defence against Wales in Wellington on September 11. They also face Samoa, Fiji and Namibia in Pool D.
