The Ch'ŏnma-ho or spelled as Chonma-ho (Chosŏn'gŭl: 천마호; Hanja: 天馬號), which means "Sky Horse" or Pegasus, is one of North Korea's secretive indigenous main battle tank designs. The tank is also known by the name of 천리마 전차 (千里馬 or the "Chollima Tank"). The original Ch'ŏnma-ho is based on the Soviet T-62. There are at least five different operational versions of the Ch'ŏnma-ho. Since its inception, the Ch'ŏnma-ho has been upgraded various times. Not much is known about it, and its most recent public appearance was the 65th Anniversary Parade held in Pyongyang, North Korea, on 10 October 2010, celebrating the 65th anniversary of North Korea's ruling party.
Background[edit | edit source]
After the Armistice Agreement of the Korean War in 1953, North Korea found itself in need of much more modern equipment. Prior to the start of open hostilities, North Korea had acquired 379 T-34s from the Soviet Union. According to a report to the United States Congress in 2000, the North Korean military had more or less 2,000 tanks garrisoned along the Korean Demilitarized Zone (DMZ) alone. This means that between the years 1954 and 2000 the North Koreans were able to stockpile over 2,000 tanks, including Soviet T-55s and T-62s and Chinese Type 59s and Type 62s. A North Korean general who defected to South Korea also said that due to a lack of fuel military exercises are limited. It is also possible that many of the older vehicles used by the North Korean People's Army are not well maintained and have suffered from years of use. This still remains true even assuming good maintenance, and the North Korean army would not be the only military experiencing this.
Although not much is known about the North Korean military after the Korean War, it is known that they have many different types of tanks. These include the Type 59 and Type 62, as well as the T-54, T-62 and possibly the T-72. The T-54 was probably sold to North Korea between 1960 and 1970, while the T-62 was reportedly sold in the mid 1980s. Unconfirmed reports indicate a few T-72s may have been provided to North Korea in the early 1990s. It is known that the North Koreans still make limited use of vintage World War II T-34s as well as the Soviet-era PT-76/85 amphibious tanks. Up to 5,400 tanks are coupled with at least 12,000 self-propelled artillery pieces and thousands of other towed artillery pieces of unknown type and number. The North Koreans also have at least nine different types of armoured personnel carriers, including the BMP-1.
Role[edit | edit source]
The Ch'ŏnma-ho has been issued to North Korea's premier armored formations, and would lead the initial attempts to break through South Korean defences. Other armour is relegated to a secondary role in this corps or to North Korea's four mechanized corps. To underscore North Korea's concept of combined arms and the importance of armour, and therefore the importance of the Ch'ŏnma-ho, North Korea's sole armour corps is directly grouped with two mechanized corps and a single artillery corps. However, this forms the second echelon of North Korea's deployment to the DMZ, with the first echelon composed of four infantry corps, and the rest in strategic reserve. This may also play a part in a defensive strategy, as the North Korean army is arrayed in depth, and the armour might be strategically placed to both provide offensive power and a second echelon composed of mobile defences to plug a South Korean breakthrough along the DMZ.  Soviet T-62. The Ch'ŏnma-ho is a direct copy of the T-62 with several upgrades.The Ch'ŏnma-ho is a product of North Korea's approach of Juche, or self-reliance, which also includes several indigenous self-propelled artillery pieces. The idea of juche comes from a North Korean sentiment of abandonment by their allies, China and Soviet Union/Russia. 
Production history[edit | edit source]
There might be two versions of the Ch'ŏnma-ho 1: the copy of the Syrian T-62 in the late 1970s, and an original copy exported by the Soviet Union which may be the T-62D. The Ch'ŏnma-ho is not related to the Chinese Type 62. Despite its relation to the T-62, the original version of the Ch'ŏnma-ho had thinner armour and was consequently lighter. This version of the tank has two distinctive bolts on the bottom portion of the upper glacis plate. The Ch'ŏnma-ho I name was also given (at least by the West and South Korean white papers) to the imported T-62, which was later slightly upgraded to the IM version. Although no dates are available, the Ch'ŏnma-ho I was later upgraded to the II version with a laser rangefinder above the mantlet. According to online sources this Ch'ŏnma-ho was upgraded once again, probably in the mid-1980s, with a 'boom shield'. The Ch'ŏnma-ho III might have also seen an armour upgrade with the addition of full-hull skirting and a new thermal shroud for the original 115 mm main gun.  A conceptual drawing of the Ch'ŏnma-ho, with several upgrades, including the light explosive reactive armour.The most modern Ch'ŏnma-ho tanks seem to be the IV and V versions. The Ch'ŏnma-ho IV is fitted with what resemble EDZ light explosive reactive armour bricks. Judging by photographs, these are mounted specifically on the turret side, with at least eight bricks per side. The Ch'ŏnma-ho IV is reported to be upgraded with new side-mounted smoke launchers. North Korea is rumored to have received a few examples of the T-72s after 1992, and possibly a single T-90 S main battle tank in August 2001. Any conclusion regarding whether the Ch'ŏnma-ho has been upgraded to the standards of either the T-72 or the T-90S would be highly speculative at this point.
Around 90% of the Ch'ŏnma-ho is indigenously produced. There is evidence, however, that North Korea has purchased entire engines, or engine components, from Slovakia. Furthermore, it is thought that ceramic components, possibly for an upgraded armour scheme, are from foreign sources, as well as fire control components. It is not clear how much is indigenously produced in regards to the different variants of the Ch'ŏnma-ho. The figure of 90% could have changed considerably between the original Ch'ŏnma-ho I and the Ch'ŏnma-ho V, although it should be kept into consideration that many of the major features are probably purchased from abroad - especially for the upgrades of the tanks. It is not clear how much North Korea can afford on producing on its own, or how much it can afford to import for that matter. It is thought that North Korea is considerably low on resources, especially money, and this belief has been perpetuated after North Korea's nuclear test incidents in 2006. It is possible that Russia is supplying North Korea with several components for North Korea's tank projects which include the Ch'ŏnma-ho and quite possibly the M-2002, although no hard evidence can support this claim.
In August 2010 North Korean media revealed images of its new main battle tank the Pokpung-ho (also known as the M-2002), which had been rumoured to have been under development since the early 1990s and to have undergone performance trials in 2002. While precise details of its capabilities remain unclear, the Pokpung-ho appears to be simply a further improvement of the Ch'ŏnma-ho. The news concerning North Korea's future main battle tank has certainly driven South Korea to look for outlets for their own national tank programs, including the future South Korean Main Battle Tank, the K2.
Deployment history[edit | edit source]
It is unknown which units of the Korean People's Army might be outfitted with the Ch'ŏnma-ho. It is clear that the Ch'ŏnma-ho is a general replacement for previously employed tanks, including the T-62, T-34 and Type 59 medium tanks. It is very possible that the Ch'ŏnma-ho will equip the spearhead and elite of North Korea's armoured forces. They are apparently deployed in sufficient numbers to be strategically significant. There might be as many as 800 T-62s in addition to the over 1000 Ch'ŏnma-ho's in the North Korean army, of which any number could be one of the five Ch'ŏnma-ho variants.
Models[edit | edit source]
- Ch'ŏnma-ho I (Ga) - Lightened copy of the T-62 with thinner armour
- Ch'ŏnma-ho II (Na) - Similar to a stock T-62, but has several differences, has a laser rangefinder housed in a blister above the main gun atop the turret (though the original T-62 doers have a laser rangefinder, the Ch’onma-ho 1 do not – and the laser rangefinder of the T-62 is an integral part of the fire control system, rather than an add-on part like on the Ch’onma-ho 2). Fitted with spaced appliqué armor on the turret in a ring around the turret ("boom shield") – thin plates of steel welded onto the turret atop bars provide a space between the shields and the turret armor to provide the equivalent of spaced armor, as well as doubling as turret baskets for crew equipment and vehicle equipment.
- Ch'ŏnma-ho III (Da) - A simple progressive upgrade of the Ch’onma-ho 2, with a thermal sleeve for the main gun and armored track skirts added. It is possible, but considered unlikely, that lugs for ERA have been added since its introduction; if they are present, they would be most likely found on the glacis and turret sides. A night vision upgrade.
- Ch'ŏnma-ho IV (Ra) - Greatly upgraded armor protection, including composite armor on the glacis and turret front, and appliqué or thickened armor elsewhere. Even the appliqué and/or thickened armor appears to be more advanced than earlier models, does not appear to have gained a huge amount of weight. A ballistic computer was added to the fire control suite, and the fire control suite has been integrated into a complete system rather than being a patchwork of upgrades. Gun stabilization has been improved. Radios are improved, and the suspension beefed up. The new engine is a 750-horsepower model which can lay a thick, oily smoke screen by injecting diesel fuel into its exhaust. Lugs for ERA (similar to the Russian Kontakt-3 ERA) added to turret sides, and lugs on the armored track skirts and on the glacis. Lugs for a relatively small amount of ERA bricks on the turret front; the ERA on the turret front would only protect 40% of hits to the turret front. On side of turret, clusters of four smoke grenade launchers; at the rear of the turret another cluster of four smoke grenade launchers, firing backwards instead of forwards.
- Ch'ŏnma-ho V (Ma) - Armor upgrades derived partially from the T-90S and T-72S, as well as a better ballistic computer and the addition of the aforementioned thermal imagers. Upgraded main gun – a copy of the 125mm 2A46 gun, complete with an autoloader. The fire control system replaced with one matching the new main gun, and the spent shell ejection system dispensed . Use wider tracks.
- Ch'ŏnma-ho VI (Ba) - Newly improved armor. fitted with rubber plates to defend shape charged warheads. The chassis has been stretched, and six roadwheels per side instead of five. 
- Ch'ŏnma-ho II - Designation for imported T-62
- Ch'ŏnma-ho IM - Improved imported T-62
Variants[edit | edit source]
- Ch'ŏnma-ho ARV - Armoured recovery vehicle with a casemate superstructure
- Ch'ŏnma-ho Command - Command variant of the tank with a fake main gun
- Juche-Po - Self-propelled artillery gun on a modified Ch'ŏnma-ho chassis. The Juche-Po is an improvement over the Tok-Ch'ŏn artillery piece, which was mounted on an ATS-59 chassis. There are at least four M1991 versions of the Juche-Po, each mounting a different gun; the D-30 122 mm, D-74 122 mm, the M-46 130 mm and the ML-20 152 mm howitzer. A fifth M1992 version is armed with the SM-4-1 130 mm howitzer. These artillery pieces can be identified by their six road wheels, as compared to the Tok-Ch'ŏn's five, and a prominent recoil cylinder which protrudes from the turret. Another major difference is the fact that the Juche-Po has a fully encased rounded turret, as opposed to the older open-topped self-propelled artillery pieces used previously.
Operators[edit | edit source]
- Iran - 150 ordered in 1981 from North Korea and delivered between 1982 and 1985.
- North Korea - 470 were produced between 1980 and 1989 (the original order was placed in 1976). Overall more than 1,200 were produced. as many as 1,000 are currently in service in addition to roughly 800 T-62's (Which are capable of receiving the same upgrades)
