Just a day after Donald Trump unleashed "The Mother of All Bombs", the US National Nuclear Security Administration announced the successful field test in Nevada.

The device dropped was a modernised gravity nuclear bomb.

The NNSA and the US Air Force completed the first qualification flight test of the B61-12 gravity nuclear bomb at the Tonopah Test Range.

It comes as war tensions reach boiling point in North Korea – with another nuclear test expected this weekend.

The test was intended to evaluate the weapon’s “non-nuclear functions” and the capability of the F-16 fighter to successfully deploy the bomb.

An F-16 fighter from Nellis Air Force Base dropped the “non-nuclear test assembly".

The B61-12 is a modernised version of the B61 gravity bomb – the mainstay of the Air Force’s nuclear arsenal.

Paul Waugh claimed the test will "ensure the future for bombers and dual-capable aircraft supporting NATO".

It comes at a time of heightened global tension over the situation in North Korea.

Intelligence officials have revealed the US has placed two devices capable of firing Tomahawk missiles into the Korean peninsula.

American bombers have also been positioned in Guam ready to strike if necessary.

And the US Carl Vinson has led a fleet of warships to the peninsula, along with Japanese allies.
