2017 North Korean missile tests

Several missile tests were conducted by North Korea throughout 2017.

April
On April 4, 2017, North Korea launched a medium-range ballistic missile which reached the Sea of Japan. The test came after a day of celebration for North Korea's Eternal President Kim Il-sung. US Secretary of State Rex Tillerson responded by saying the United States had not changed its stance on North Korea and would not comment further.

On April 16, 2017, a KN-15 medium-range ballistic missile was launched and failed almost immediately, according to the United States Military and the South Korean Armed Forces. The US National Security Advisor, H.R. McMaster, said "all options are on the table" as possible reactions.

In the early hours of April 29, 2017, another missile was launched from Bukchang in the South Pyeongan province, and failed shortly after liftoff. According to the US Pacific Command, the missile did not leave North Korean territory. This launch occurred only hours after a meeting of the UN Security Council condemned North Korean missile and nuclear testing activities again. US President Donald Trump called this action disrespectful to China.

May
On May 14, 2017, a ballistic missile test was carried out. The Hwasong-12 missile flew for 30 minutes, covering a distance of 700 km and reaching an altitude upwards of 2000 km.

June
On June 8, 2017 North Korea fired four anti-ship missiles off its east coast, near the port city of Wonsan.

July
On July 4, 2017 North Korea tested an ICBM. The missile flew for approximately 40 minutes, falling 930 km away from the launch site in the Sea of Japan. The missile, named the Hwasong-14, reached an altitude of 2,802 km. It is estimated that the missile has the capability of reaching 6,700 km on a standard trajectory, meaning that although it would not be capable of reaching the Contiguous United States, it would be able to hit anywhere in Alaska. The test prompted an Emergency Debate of the United Nations Security Council.

On July 28, 2017, North Korea launched an additional ballistic missile from Chagang Province, reaching an altitude of 3,000 km (1,865 mi). Jeffrey Lewis, researcher at the James Martin Center for Nonproliferation Studies, estimated that the missile could have a range of approximately 10,000 km based on its 45-minute flight time. With this range, the missile could potentially reach major U.S. cities such as Denver and Chicago. This is the fourteenth missile test conducted by North Korea in the year 2017. As with the missile launched on July 4, this missile has also been estimated to be of type Hwasong-14.

August
On August 26, 2017, three short-range missiles were launched around early morning from a site in Gangwon Province, with the second one appears to have blown up almost immediately while another two flew about 250 km (155 miles) in a north-eastern direction, before crashing in the Sea of Japan.

Mid-range launch over Japan
On August 29, 2017, at 5:57 am KST, North Korea launched a Hwasong-12 ballistic missile that passed over Hokkaido, the second largest island of Japan. The missile travelled 2700 km and reached a maximum height of 550 km. This was the second successful test flight of the Hwasong-12 missile, following three failed tests.

Japanese citizens living beneath the missile’s flight path received a J-Alert message on their cellphones at 6:02 a.m., just four minutes after the projectile was launched, rousing some from sleep.

Japanese Prime Minister Shinzo Abe called this test "a reckless act of launching a missile that flies over our country is an unprecedented, serious and important threat." North Korea had previously carefully avoided sending test missiles over Japan by using highly lofted trajectories, and had sent more recent satellite launches to the south avoiding Japan. The missile was at an altitude of about 500 km over Japan, well into space, and the Japanese military did not attempt to shoot down the missile.

The missile was launched from Pyongyang Sunan International Airport, presumably using a mobile launcher. It reportedly broke into three parts before splashing down in the Pacific Ocean; it is unclear if this was intentional. Given North Korea's geographical position, for a non-lofted test flight at this range there was no other practical alternative to passing over Japan.

This was the fifth time North Korea fired a rocket over the Japanese archipelago,  although this launch was the first missile launch, as the previous four were satellite launches or attempts.

September
On September 15 at about 6:30am KST, North Korea fired a Hwasong-12 missile over Hokkaido, Japan, for the second time. The missile traveled 3700 km and reached a maximum height of 770 km; this is the furthest distance any North Korean IRBM missile has ever reached.



November
On November 28, North Korea launched another ballistic missile, the first in over 2 months. The missile was said to have flown very high up in the air and landed near Japan’s exclusive economic zone. The test was caused by joint Japanese and US naval drills ended up on November 26, 2017, in a show of force aimed at North Korea.
