The date of the retrieval operation is kept secret for security reasons, according to RTBF. A ship with 50 soldiers and a helicopter will escort the ingots to Belgium.
The gold, estimated at $7 billion, is stored at a depth of over 65 feet in a repository with 3-feet thick walls. The password-protected storage can be opened only with an almost 3-inch key, of which there are no copies.
The ingots were deposited to the UK, a country with the most secure storage in the world, out of fear of Nazi theft. The UK also stores French and the United States gold.
Belgium pays over $280,000 in rent for the storage every year.
