Key Steps In North Korea's Weapons Development

INSUBCONTINENT EXCLUSIVE:
and intercontinental missile launches, five months after its last ICBM launch amid a rapid diplomatic thaw.Here are the key steps in the
the late 1970s on a version of the Soviet Scud-B missile with a range of around 300 kilometres (around 200 miles), carrying out a first test
in 1984.Between 1987 and 1992, it begins developing longer-range missiles, including the Taepodong-1 (2,500 km) and Taepodong-2 (6,700
km).The Taepodong-1 is test-fired over Japan in 1998 but the following year, Pyongyang declares a moratorium on such tests as ties with the

than the first
Kim Jong Un succeeds his father Kim Jong Il -- who dies in December 2011 -- and oversees a third nuclear test in 2013.2016, Japanese Waters
ReachedThere is a fourth underground nuclear test in January 2016, which Pyongyang claims is a hydrogen bomb.In March, Kim Jong Un claims
the North has successfully miniaturised a thermonuclear warhead, and in April it test-fires a submarine-launched ballistic missile.On August
3, it fires, for the first time, a ballistic missile directly into Japanese-controlled waters
Later that month, it successfully test-fires another submarine-launched ballistic missile.There is a fifth nuclear test on September 9.2017,
Japan And Guam Under ThreatBetween February and May, the North tests a series of ballistic missiles that fall into the Sea of Japan
Pyongyang claims these are exercises to hit US bases in Japan.A test on May 14 is of a "newly developed mid/long-range strategic ballistic
rocket, Hwasong-12", Pyongyang says
It flies 700 kilometres before landing in the Sea of Japan.Two months later, North Korea announces it successfully tested on July 4 -- the
US independence day -- an ICBM capable of reaching Alaska, a gift for the "American bastards"
There is a second successful ICBM test on July 28.Hours after US President Donald Trump threatens Pyongyang on August 8 with "fire and fury"
over its missile programme, the North says it is considering strikes near US strategic military installations in Guam.Largest Nuclear Test
YetOn September 3, North Korea conducts its sixth and largest nuclear test
Monitoring groups estimate a yield of 250 kilotons, which is 16 times the size of the 15-kiloton US bomb that destroyed Hiroshima in 1945.On
September 15, less than a week after the UN adopts an eighth series of sanctions, North Korea fires an intermediate-range missile over
Japan.On November 20, Washington declares North Korea a state sponsor of terrorism, a day before adding to pressure on the isolated state
with fresh sanctions.On November 29, North Korea launches a new Hwasong-15 ICBM, which it claims could deliver a "super-large heavy warhead"
anywhere on the US mainland.Analysts agree the rocket is capable of reaching the US but voice scepticism that Pyongyang has mastered the
advanced technology needed to allow the rocket to survive re-entry into the Earth's atmosphere.Weeks later on December 13, Kim vows to
make North Korea the "world's strongest nuclear power".Olympic Detente Triggers Thaw, 2018In his New Year speech, Kim states that the
development of North Korea's nuclear force had been completed.Catalysed by the Winter Olympics in the South, a rapid diplomatic thaw
begins in February.On April 21, Pyongyang declares that nuclear blasts and ICBM launches will cease immediately and the atomic test site at
Punggye-ri will be dismantled to "transparently guarantee" the end of testing.Kim adds that the possession of nuclear weapons was "the firm
guarantee by which our descendants can enjoy the most dignified and happiest life in the world".(This story has not been edited by staff
