The recent flight tests of an upgraded nuclear bomb in the Nevada desert mean that the United States is preparing for war, military analyst Oleg Glazunov said.
Despite posing no direct threat to Russia, the recent test of the bomb "means that the Americans are preparing for war", Glazunov said.
He also mentioned the role played by the powerful military lobby, which will keep pushing for ever newer weapons in the US arsenal.
"The upgraded version of the B61 bomb will be used to replace the almost 200 unguided B61s the US now has in Europe. The Americans will say that this is done against Iran, but there is also Russia out there, right?" Glazunov noted.
He added that the recent tests of the B61 nuclear bomb could also be meant to intimidate North Korea.
Glazunov said that he doesn’t think that the Americans are really going to use exactly this type of nuclear bomb against North Korea.
"However, this could be an attempt to show that the US is developing something new to scare them," Glazunov continued.
On August 8, the United States completed a second series of flight tests for an upgraded version of its B-61 nuclear bomb, following the first tests in March.
An inert version of the B61-12 gravity bomb was dropped from an F-15E fighter-bomber at the Tonopah Test Range in Nevada on August 8 to test its non-nuclear functions as well as the plane's ability to carry the weapon, the National Nuclear Security Administration (NNSA) said in a statement.
The tests were conducted as part of a program to extend the life of the B61 gravity bomb, which is one of the main pillars of the US Air Force’s nuclear arsenal.
"The B61-12 life extension program is progressing on schedule to meet national security requirements," Phil Calbos, acting NNSA deputy administrator for defense programs, said. "These realistic flight qualification tests validate the design of the B61-12 when it comes to system performance."
The March tests, like the August one, were carried out by F-15E fighter jets at Tonopah Test Range.
Experts say that the B61-12 can be ferried by B2A and B21 bombers as well as by F16C/D, F16 MLU, F35 and PA-200 aircraft.
According to the NNSA, the first production unit of the B61-12 is scheduled to be completed in 2020.
The B61, one of the main elements of the US nuclear triad, is an upgraded version of a nuclear bomb developed in the late-1960s. It is described as the most dangerous nuclear device ever produced because its yield can be adjusted between the equivalent of 50,000 tons and 300 tons of TNT.
The B61 is 3.58 meters long and weighs between 320 kilograms and 500 kilograms.
