(CNN) -- In a reversal from the Trump administration, the State Department revealed the number of nuclear weapons in the US stockpile for the first time in four years on Tuesday.

The US has 3,750 nuclear warheads in its stockpile and 2,000 are waiting to be dismantled, according to a release from the State Department, which emphasized the importance of transparency.

The release of the "Transparency in the U.S. Nuclear Weapons Stockpile" fact sheet comes as the Biden administration is conducting a review of its nuclear weapons policy and capabilities ahead of a 2022 meeting of the Nuclear Non-Proliferation Treaty conference, where the US and other nuclear powers who are party to the Treaty will review each signatory's disarmament commitments.

"Increasing the transparency of states' nuclear stockpiles is important to nonproliferation and disarmament efforts, including commitments under the Nuclear Non-Proliferation Treaty, and efforts to address all types of nuclear weapons, including deployed and non-deployed, and strategic and non-strategic," the State Department said.

During the 2020 presidential campaign, then-candidate Joe Biden said that the US doesn't need new nuclear weapons and that his "administration will work to maintain a strong, credible deterrent while reducing our reliance and excessive expenditure on nuclear weapons."

After Biden's first budget request, however, critics rapped the President for proposing to continue all parts of the spending plans left by the Trump administration, including "the controversial additions made by President Trump to the Obama-era program, such as additional, more usable lower-yield nuclear capabilities," the Arms Control Association said.

The ACA called Biden's budget request inconsistent with his "stated desire to reduce the role of nuclear weapons in U.S. policy and seek new risk reduction and arms control arrangements with Russia and perhaps China."

In Tuesday's release, the State Department said there are 3,750 nuclear warheads in the US nuclear stockpile as of September 2020, an 88 percent decrease from its maximum number of 31,255 in 1967, according to the department.

The US also dismantled 11,683 nuclear warheads from 1994 to 2020, including 711 nuclear warheads since September 30, 2017. Two thousand nuclear warheads are retired and waiting to be dismantled, the department also said.

In 2010, the Obama administration revealed the US had 5,113 nuclear warheads in the stockpile as of September 30, 2009. According to data released in 2015, the US had 4,717 nuclear warheads in the stockpile as of September 2014.
