North Korea's Rockets and Missiles: 5 Interesting Facts
1 of 6
North Korea's Rockets and MissilesNorth Korea's missile program is shrouded in secrecy, which helps the outlaw nation keep the rest of the world guessing.
Still, Western experts have learned a fair bit about Pyongyang's stable of rockets and missiles over the years by analyzing test flights, satellite photos and other data. Here are five of the most interesting things they've figured out.
FIRST STOP: Soviet Origins of Missiles

Soviet OriginsThe Hermit Kingdom's missile program is based primarily on Soviet Scuds, which apparently entered the country via Egypt in the 1970s. North Korea was building its own Scud version, called the Hwasong-5, by the mid-1980s, and moved onto bigger and more powerful missiles after that. [North Korea's Missile Capabilities Explained]
NEXT: Poor Accuracy

Poor AccuracyNorth Korea's missiles have lousy accuracy compared to those developed by the United States, experts say. Pyongyang's Hwasong line, for example, can reach targets a few hundred miles away, but with an accuracy of just 0.3 miles to 0.6 miles (0.5 to 1 kilometer).
A missile called the Nodong can fly 620 miles to 800 miles (1,000 to 1,300 km), but its estimated accuracy is even worse — 1.8 to 2.5 miles (3 to 4 km). Such missiles can't reliably hit military targets, but they can certainly strike larger targets such as cities.
NEXT: Iran's Help

Cooperation with IranNorth Korea has apparently cooperated extensively with fellow pariah nation Iran on rocket and missile technology. For example, the third stage of Pyongyang's Unha-2 rocket is very similar to the upper stage of Iran's Safir-2 launcher, physicists David Wright and Theodore Postol noted in a 2009 report.
NEXT: Satellite Success

Satellite Launch SuccessNorth Korea joined the ranks of satellite-launching nations last December, when its Unha-3 rocket launched a small satellite to Earth orbit.
This breakthrough came after three consecutive failures — one in 1998, one in 2009 and another in April 2012. North Korean officials didn't always admit to these mishaps, however. For example, they claimed that the Kwangmyongsong-1 ("Bright Star 1") satellite reached orbit in 1998 and broadcast patriotic songs into space. [Unha-3 Rocket Explained (Infographic)]
NEXT: Nuclear Warheads Possible

Nuclear Warheads PossibleNorth Korea has been ratcheting up its bellicose rhetoric lately, threatening to launch nuclear strikes against Washington, D.C. and other American cities.
While the rogue nation's nuclear-weapons program is thought to be at a relatively primitive stage, Pyongyang may indeed already possess warheads small enough to be carried large distances by a ballistic missile, experts say. "Having something that's around 1,000 kilograms, or maybe somewhat smaller than that, unfortunately does not seem impossible," Wright told SPACE.com. "We don't really know, but I think you have to take seriously that they could well be there."
Most analysts doubt, however, that North Korean missiles are powerful enough to deliver a nuclear weapon to the American mainland. The tough talk from Pyongyang is primarily bluster aimed at wringing concessions out of the international community and building support for young leader Kim Jong-Un at home, they say.
