It marks the climax of a 16-year search for the lost aircraft by Lincolnshire farmer and aircraft enthusiast David Cundall.
Mr Cundall, 63, has poured tens of thousands of pounds into the venture - he says he stopped counting when the cost hit £130,000 - and hopes the recovered aircraft can be restored and eventually returned to flight.
And now, following the suspension of European Union sanctions on Burma which David Cameron called for in April, a dig to find the lost planes is finally due to begin in January.
Speaking before the announcement, Mr Cundall said: "It is the biggest project I have ever taken on in my life. I did not realise it would take 16 years or quite a large amount of personal money. But I do not regret it.
"I have always admired the Spitfire. It has a very special place in British history, from the Battle of Britain. To find one Spitfire would be a major find, let alone 36."
Mr Cundall first heard of the story of the burial in 1996 and subsequently travelled to Burma to corroborate the rumours with eyewitnesses. An electronic scan on the site in 2004 revealed some material of "high electrical conductivity" buried between 30ft and 50ft below the ground.
Mr Cundall insists he is "100% confident" that the objects detected below are the missing Spitfires.
Around 17 people will fly out to Burma for the excavation, including British archaeologists, academics from Leeds University and an American film crew. It is hoped that digging will begin in the first weeks of January and that the first evidence of the Spitfires will surface five to six days later.
