Such programs are also commonly referred to as black projects or deep black programs and are of an extremely covert and secretive nature.
Unacknowledged Special Access Programs are said to be highly compartmentalized and even those with the necessary security clearances can only access the information on a “need to know” basis. These uSAPs are also hidden from public oversight and accounting.
The US Congress and the US President have no access to this information because they do not hold the necessary security clearances and neither do they have a “need to know”.
Then, in 2013, NSA whistle-blower Edward Snowden leaked top secret government documentation which proved that such Special Access Programs do indeed exist. According to the Washington Post, the documents revealed how $52.6-billion was put towards such operations in the fiscal year 2013.
Whilst the black budget documents indicated that billions of dollars are spent on these covert operations each year, others suggest that the figure is actually much close to trillions of dollars.
The majority of the finance is allegedly unaccounted for and is going into projects which, in an official capacity, do not exist.
According to former Canadian defense minister, Paul Hellyer (the only G8 official to speak on the issue):
They claim that US officials who were contacted prior to publishing the news had shown concerns over the “risk to intelligence sources and methods”.
