This year alone, North Korea has attempted 17 missile launches. The Nuclear Threat Initiative (NTI) maintains a database and analysis of North Korea's ballistic missile testing, along with its successes and failures, if they are known.
In early September 2017, North Korea appeared to be planning another missile launch, possibly of an intercontinental ballistic missile (ICBM) to show off its claimed ability to target the United States with nuclear weapons, South Korea's Defense Ministry reported.
Here's the list of North Korea's missile tests -- short-, medium- and long-range -- going back to its first test in 1984.
- from its east cost, but the rocket fails. The missile is believed to be either a Musudan, an intermediate range missile which keeps failing, or the older medium-range Scud ER.
- missile. Seoul's Joint Chiefs of Staff say in a statement that the missile fired from the North's eastern coastal town of Sinpo flew about 37 miles.
- missile from the Sinpo Shipyard. "The launch failed very early on, so that makes it harder to know exactly what they were trying to do," Susan Thornton, acting assistant secretary of state for East Asian and Pacific Affairs, says of the launch.
- . Once again, the missile explodes shortly after liftoff.
- , and say this test was successful. They also claim it is capable of delivering a nuclear warhead to U.S. territories. It travelled some 400 miles before touching down in the Sea of Japan.
- . Although the missile is designed to be fired from a submarine, this was a land-based test, and was successful. The launch came after South Korean President Moon announced the appointment of national security aides and the nominee for a new foreign minister.
- its third test in three weeks.
- (ICBM). North Korean state television called it an historic event as Kim Jong Un reportedly oversaw the successful launch that the North is calling the Hwasong-14.
- , which flew longer and higher than the first test. According to Japanese government officials it flew for about 45 minutes - about five minutes longer than the ICBM North Korea test-fired on July 4.
- , one of which is believed to have exploded shortly after takeoff. The three missiles were launched in a span of 30 minutes.
- . South Korea said the missile flew 1,677 miles and reached a maximum height of 341 miles.
- . The rocket was fired from North Korea's west coast and tracked separately by the governments Japan and South Korea. South Korean media reported that the rocket may have failed, but provided no other details.

- which managed to launch about 620 miles high after several failed attempts in recent months.
- July 18th, 2016: North Korea fires two Scuds and one medium-range Nodong missile.

- October 19th, 2016: North Korea launches another Musudan missile, which also fails.
- February 8th, 2015: North Korea launches five short-range missiles from the coastal town of Wosan. The flew roughly 125 miles before crashing into the sea.

- May 8th, 2015: North Korea successfully fires a submarine-launched ballistic missile (SLBM), the Polaris-1, from the Sinpo Shipyard.
- November 28th, 2015: North Korea attempts to launch another Polaris-1. However, this launch was unsuccessful.
- December 21st, 2015: North Korea claims that it successfully launched another Polaris-1 SLBM.
North Korea had no known missile failures in 2014, according to NTI. However, all of the launches observed involved short-range SCUD or KN-02 missiles or medium-range Nodongs. The North did not test a multi-stage long-range missile this year.
- February 27th, 2014: North Korea fires four short-range Scud missiles from its Kittaeryong Missile Base to protest U.S./South Korean military exercises.
- March 3rd, 2014: North Korea fires two short-range Scud missiles from Wonsan Kalma International Airport.
- March 26th, 2014: Amid an international meeting in the Netherlands to discuss North Korea's nuclear threat, the country launched two medium-range Nodong missiles into the sea between itself and Japan. The missiles were fired from Sunchon airbase and travelled some 403 miles before crashing.
- June 26-29, 2014: North Korea fires three short-range ballistic missiles into the sea.

- April 12th, 2012: An Unha-3 missile is fired from the Sohae Satellite Launching Station in North Pyongyan Province. This was Kim Jong Un's first missile test, and it failed, flying about 120 km into the air before it exploded, according to NTI, which also said that although this missile failed, it was seen as embarrassing to President Obama, who had attempted to restart talks for another missile testing moratorium.
- December 12th, 2012: Another Unha-3 missile is fired from the Sohae Satellite Launching Station.
- July 5th, 2009: Three years after the 2006 tests, North Korea tested eight missiles. The multi-state Unha failed, exploding in its second or third stage over the Pacific. Two Nodong and five Scud-C missiles were successully launched, NTI notes.
- July 5th, 2006: On Independence Day in the U.S., North Korea tested seven missiles, one similar to the 1998 test that started the moratorium. This one failed 42 seconds into its flight, NTI notes. The other six were successful launches, but there is some dispute over what kind of missiles these were. Some have been counted in NTI's database as Nodong missiles, and others were counted as Scud-C missiles.
- August 31st, 1998: This was, according to NTI, one of the most significant missile tests carried out by the North for several reasons. This was Kim Jong Il's first missile test, and the missile was its first multi-stage rocket, the Taepodong-1. This was also the first of the missiles launched to overfly Japan, causing international outrage. Although this launch failed, it did fly about 4000 km before exploding in its third stage. And it nonetheless led to talks between the U.S. and North Korea and a moratorium on missile tests that would last for the next eight years.
- May 29-30, 1993: Four missiles were launched from Tonghae, though not much is known. North Korea appears to have successfully launched a Nodong for the first time, though, notes NTI. Also, several Pakistani and Iranian observers were present -- NTI said that it's possible the North was trying to interest buyers in its missiles.
- June: There is not much known about this test launch of a Nodong missile from Tonghae. NDI cites Japanese reports about this missile test, which is likely to have failed early in its flight.
- July: The North carried out the successful launch of Scud-C from Chihari Missile Base, in Kangwon-do Province, near the DMZ. According to NTI, this is the sole missile launched from this location. It landed in the Sea of Japan.
- May: This was believed to be the North's first test of a Nodong missile, also at Tonghae. It was, according to NTI, observed by U.S. intelligence while it was on the launchpad, but is believed to have had a "catastrophic failure upon launch."
- June: The North carried out its first known test of a Scud-C, which landed in the Sea of Japan. This test was successful.
- May: At Tonghae, North Korea may have tested a missile - possibly a Scud-B or Scud-C. NTI cited a statement by the South Korean Defense minister on this launch, but also stated that it is as likely that no launch took place at this time.
- April - September: According to NTI, North Korea carried out its first known missile tests -- of Scud-B missiles. These have a range of about 300 km and a payload of at least 500 kg. The North conducted at least six launches at Tonghae Satellite Launching Ground, possibly over the course of several months, rather than days. At least three succeeded and at least three failed.
