New York – U.S. defense officials have claimed that North Korea has recently carried out another ballistic missile engine test.
According to officials, the test which was conducted on Friday was the third such test in recent weeks using similar technology.
CNN quoted one official as saying that engine technology could possibly be used in a eventual intercontinental ballistic missile.
In a reaction indicating show of force following the increased provocations from North Korea, the US Marines have deployed F-35Bs to South Korea for the first time as part of an exercise that began Friday.
North Korea had last week conducted a ground jet test of a newly developed high-thrust missile engine at its Tongchang-ri rocket launch station.
U.S. Secretary of State Rex Tillerson had said earlier during his visit to South East Asia that Washington would consider military action against North Korea if it was provoked.
