Quick Answer: North Korea launched the Kwangmyŏngsŏng-4 satellite on February 7, 2016, using a Unha-3 rocket from the Sohae Satellite Launching Station. The U.S. and allies condemned the launch as a disguised test of ballistic missile technology, violating UN Security Council resolutions.

Key Facts

Launch date: February 7, 2016
Satellite name: Kwangmyŏngsŏng-4
Launch vehicle: Unha-3 rocket
Launch site: Sohae Satellite Launching Station
UN resolution violated: UNSCR 1874 and 2270

Overview

North Korea's 2016 satellite launch marked a significant escalation in its space and missile programs. Conducted on February 7, 2016, the mission deployed the Kwangmyŏngsŏng-4 satellite using a three-stage Unha-3 rocket launched from the Sohae Satellite Launching Station.

The launch drew immediate international condemnation, with the United States, South Korea, and Japan asserting it was a covert test of long-range missile technology. Despite North Korea's claim of peaceful scientific intent, experts noted the rocket's design closely resembled intercontinental ballistic missile (ICBM) systems.

Launch occurred on February 7, 2016, at approximately 9:00 AM local time from the Sohae facility in North Korea’s northwestern region.
Kwangmyŏngsŏng-4 was declared a success by North Korean state media, said to be an Earth observation satellite for weather and communications monitoring.
The Unha-3 rocket used a liquid-fueled, three-stage configuration, with each stage separating as the satellite ascended into orbit.
Tracking data confirmed the satellite reached orbit, though it tumbled uncontrollably and failed to transmit meaningful data.
The launch violated multiple UN Security Council resolutions, including UNSCR 1874 (2009) and UNSCR 2270 (2016), which banned North Korea from conducting any missile-related activities.

How It Works

The Unha-3 rocket and Kwangmyŏngsŏng-4 satellite represented a coordinated effort in North Korea’s space program, combining rudimentary satellite design with long-range propulsion systems. Each stage of the launch involved precise engineering and fuel management.

Unha-3 Rocket: A three-stage, liquid-fueled launch vehicle derived from Soviet Scud and Nodong missile technology. Each stage used UDMH fuel and nitrogen tetroxide oxidizer.
First Stage: Powered by four clustered engines producing approximately 1.2 million pounds of thrust, burning for about 150 seconds before separation.
Second Stage: Used a single engine generating roughly 50,000 pounds of thrust, operating for 240 seconds to continue the ascent.
Third Stage: Smaller propulsion system responsible for orbital insertion, with a burn time of around 50 seconds and a guidance system for satellite deployment.
Kwangmyŏngsŏng-4 Satellite: Weighed approximately 100 kg, equipped with low-resolution imaging sensors and radio transmitters broadcasting revolutionary songs.
Orbital Parameters: Entered a sun-synchronous orbit at an altitude of 490 x 500 km, inclined at 97.4 degrees, completing one orbit every 94 minutes.

Comparison at a Glance

Comparing North Korea’s 2016 launch to previous attempts and regional counterparts reveals technological progress and strategic intent.

Event	Date	Outcome	Significance
Kwangmyŏngsŏng-1	April 5, 2009	Failure (failed to reach orbit)	First attempt using Unha-2 rocket; drew international sanctions.
Kwangmyŏngsŏng-3 (Attempt 1)	April 13, 2012	Failure (exploded mid-flight)	Used Unha-3 rocket; launch condemned by UN.
Kwangmyŏngsŏng-3 (Attempt 2)	December 12, 2012	Partial success (reached orbit, non-functional)	First satellite in orbit; proved stage separation capability.
Kwangmyŏngsŏng-4	February 7, 2016	Success (reached orbit, limited function)	Improved reliability; demonstrated persistent launch capability.
South Korea’s Naro-1	January 30, 2013	Success	First successful indigenous launch; used Russian first stage.

While North Korea’s satellites remain primitive compared to those of South Korea or Japan, the 2016 launch demonstrated improved reliability and orbital accuracy. It signaled a maturing missile program with potential dual-use applications for military ICBMs.

Why It Matters

The 2016 launch had far-reaching implications for regional security and nonproliferation efforts. It underscored North Korea’s determination to advance its ballistic missile capabilities under the guise of space exploration.

Triggered new UN sanctions in March 2016, expanding asset freezes and travel bans on North Korean officials and entities.
Demonstrated advancements in staging and guidance critical for developing intercontinental ballistic missiles capable of reaching the continental U.S.
Strengthened regional alliances, prompting increased military cooperation between the U.S., South Korea, and Japan.
Escalated tensions on the Korean Peninsula, contributing to a cycle of missile tests and countermeasures throughout 2016–2017.
Highlighted limitations of diplomatic pressure, as sanctions failed to halt North Korea’s progress in rocket technology.
Set precedent for future launches, including the 2017 Hwasong-14 ICBM tests that further demonstrated long-range strike potential.

The 2016 satellite launch was not merely a scientific milestone but a strategic signal. It revealed North Korea’s growing technical capabilities and its willingness to defy international norms to achieve them.
