Prince William, the FA President, was not born when plans for a national centre were first discussed 37 years ago and now the race is on for the England team to win a major trophy for the first time since 1966.
The FA, which also invited over 1,000 football dignitaries and media to witness their landmark occasion, hopes the state-of-the-art facilities will result in silverware within 15 years as well as leading to 250,000 new top-level coaches finding their way into the game.
"The lads are buzzing and feel really lucky to have facilities like this," England and Liverpool captain Steven Gerrard told reporters. "I hope it makes a difference.
"We've got the best stadium in the world and now the training facilities too so we have taken away all of the excuses for the future. Football these days is all about preparation and recovery at the top level."
England manager Roy Hodgson said: "We have a great national stadium and now a national training centre too. Facilities don't make a better football team; it is the work you do within the facilities.
"I'm rather hoping that the work that will go on here and the amount of effort we'll put in here to help produce better players and coaches will lead us one day to that elusive World Cup victory."
St George's Park is also the home of FA Learning, the FA's educational department, national coach education courses and a platform for the communication of The Future Game philosophy, which outlines a vision for the development of English football.
The complex has evolved after exhaustive world-wide research into the best sporting facilities. FA staff visited their international counterparts at Clairefontaine (France), Zeist (Netherlands), Coverciano (Italy), the Ciudad del Fútbol (Spain) as well as Premier League clubs including Arsenal and Manchester United to learn from their setups.
Among the key details at St George's Park are 11 outdoor pitches, including an exact replica of the Wembley Stadium surface; a full-sized indoor pitch and a massive indoor sports hall.
