Chronology of North Korean Missile Development
In the latest in a long series of nuclear and missile tests, North Korea on Tuesday test-fired a ballistic missile which analysts said could bring Alaska within its range.
Here are key dates in its decades-long missile program:
Late 1970s: Starts working on a version of the Soviet Scud-B (range 300 kilometers or 186 miles). Test-fired in 1984
1987-92: Begins developing variant of Scud-C (500 km), Rodong-1 (1,300 km), Taepodong-1 (2,500 km), Musudan-1 (3,000 km) and Taepodong-2 (6,700 km)
Aug 1998: Test-fires Taepodong-1 over Japan as part of failed satellite launch
Sept 1999: Declares moratorium on long-range missile tests amid improving ties with US
July 12, 2000: Fifth round of US-North Korean missile talks ends without agreement after North demands $1 billion a year in return for halting missile exports
March 3, 2005: North ends moratorium on long-range missile testing, blames Bush administration's "hostile" policy
July 5, 2006: North test-fires seven missiles, including a long-range Taepodong-2 which explodes after 40 seconds
Oct 9, 2006: North conducts underground nuclear test, its first
April 5, 2009: North Korea launches long-range rocket which flies over Japan and lands in the Pacific, in what it says is an attempt to put a satellite into orbit. The United States, Japan and South Korea see it as a disguised test of a Taepodong-2
May 25, 2009: North conducts its second underground nuclear test, several times more powerful than the first
April 13, 2012: North launches what it has said is a long-range rocket to put a satellite into orbit, but it disintegrates soon after blast-off
December 12, 2012: North launches a multi-stage rocket and successfully places an Earth observational satellite in orbit
February 12, 2013: Conducts its third underground nuclear test
January 6, 2016: North conducts its fourth underground nuclear test, which it says was of a hydrogen bomb -- a claim doubted by most experts
March 9, 2016: Kim Jong-Un claims the North has successfully miniaturised a thermo-nuclear warhead
April 23, 2016: North test-fires a submarine-launched ballistic missile
July 8, 2016: US and South Korea announce plans to deploy an advanced missile defense system -- THAAD (Terminal High Altitude Area Defense)
August 3, 2016: North Korea fires a ballistic missile directly into Japan's maritime economic zone for the first time
September 9, 2016: Fifth nuclear test
March 6, 2017: North fires four ballistic missiles in what it says is an exercise to hit US bases in Japan
March 7, 2017: US begins deploying THAAD missile defense system in South Korea
May 14, 2017: North fires a ballistic missile which flies 700 kilometers before landing in the Sea of Japan. Analysts say it has an imputed range of 4,500 kilometers and brings Guam within reach
July 4, 2017: North Korea test-fires a ballistic missile which flies 930 kilometers before landing in the Sea of Japan. Analysts say it has an imputed range of 6,700 kilometers and brings Alaska within reach
