As nuclear tensions rise on the Korean peninsula, America is busy at home – testing the B61-12 nuclear weapon, described as ‘the most dangerous ever’.

The accuracy means it’s far more lethal, according to
 military experts – despite the relatively small yield.  The gravity bomb has been described as uniquely dangerous not because of its payload – which is equivalent to 50,000 kilotons of TNT – but because it’s accurate to around 90 feet.
The bomb tested this week was not armed of course (that would violate nuclear treaties) – but non-nuclear test assemblies were dropped from an F-15E based at Nellis Air Force Base.
The test evaluated the weapon’s non-nuclear functions and the aircraft’s capability to deliver the weapon.
Donald Trump has previously spoken out about his desire to modernise America’s nuclear arsenal.
‘The B61-12 life extension program is progressing on schedule to meet national security requirements,’ said Phil Calbos, acting NNSA deputy administrator for Defense Programs.
‘These realistic flight qualification tests validate the design of the B61-12 when it comes to system performance.’
The B61-12 consolidates and replaces four B61 bomb variants in the nation’s nuclear arsenal.
The first production unit is scheduled to be completed by March 2020.
