Rocket carts of the Ming Dynasty

Ever since the founding of Ming Dynasty, the Chinese had been an avid user of rocket weapon. Early Ming Dynasty rocket cart could have an upward of six hundred rockets, but subsequent redesigns reduced the number of rockets to make the cart more mobile.

Huo Jian Che (火箭車, rocket cart)

Huo Jian Che was recorded in the sixteenth century military treatise Si Zhen San Guan Zhi (《四鎮三關志》) without any specification on its size and structure. It might be the same rocket cart mentioned by general Qi Ji Guang (戚繼光) in his book Lian Bing Shi Ji (《練兵實紀》), written five years prior to this book.

Ye Meng Xiong's Qing Che (輕車)

Although not specifically designed as a rocket cart, this lightweight war cart designed by Ye Meng Xiong (葉夢熊) does carry enough rockets to qualify as one.

Huo Gui Gong Di Che (火櫃攻敵車, lit. 'Enemy-assaulting cart with fire cabinet')

Huo Gui Gong Di Che is a type of multiple rocket launcher mounted on a two-wheeled ox cart. It is equipped with one hundred rockets and five spears. Manned by two soldiers, this is a formidable assault weapon capable of providing suppressive fire and deterring enemy assault at the same time.

 Chong Lu Cang Lun Che (衝虜藏輪車, lit. 'Hidden wheel cart of barbarian-charging')

Chong Lu Cang Lun Che is a multipurpose weapon platform that incorporates a box of forty rockets, eight spears or other polearms and two large shields, one behind the other. It uses a wheelbarrow design and thus only has one wheel.

Jia Huo Zhan Che (架火戰車, lit. 'Chariot of fire rack')

Perhaps the most well known of the Ming Dynasty multiple rocket launchers, Jia Huo Zhan Che or "rocket wheelbarrow" as it is known in the West is an extremely versatile weapon platform. It incorporates four pods of Chang She Po Di Jian (長蛇破敵箭) of thirty rockets per pod, and two pods of Bai Hu Qi Ben Jian (百虎齊奔箭) of one hundred rockets per pod, for a total of 320 rockets. In addition, it has three Bai Zi Chong (百子銃), two fixed spears, and a cotton curtain to defend against arrows.

The versatility of Jia Huo Zhan Che lies in its modular design. Unlike other multiple rocket launchers that are usually one-shot weapons, Jia Huo Zhan Che can quickly replenish its rockets by replacing spent rocket pods with fresh ones. The rocket pods and anti-personnel guns can also be detached and used as standalone weapons. On top of that. several Jia Huo Zhan Che can be chained together to form a mobile fortification similar to a wagon fort.

Gai Shi Wu Gang Che (改式武剛車, 'Modified Wu Gang Che')

Gai Shi Wu Gang Che, from 'Jun Qi Tu Shuo (《軍器圖說》)'.

Gai Shi Wu Gang Che takes the modularity of Jia Huo Zhan Che one step further: it is a two-wheeled hand cart that can be separated into two wheelbarrows. Each wheelbarrow is equipped with two small cannons, a Huo Jian Xia (火箭匣) of twenty-seven rockets per pod, and a large shield. Like Jia Huo Zhan Che, multiple Gai Shi Wu Gang Che can be chained together to form a mobile fortification. Surprisingly, it can still be used like a normal cart to carry military supply.

This weapon is named after Wu Gang Che (武剛車), a Han Dynasty horse-drawn cart famously used by general Wei Qing (衛青) to defend against nomadic Xiongnu cavalry.

The Huo Che (火車) and Hwacha (화차 or 火車) debate

Often, any topic discussing Chinese Huo Che will inevitably bring about the comparison with Korean Hwacha (and vice versa). With national pride somehow at stakes, such discussions often degenerate into meaningless bickering and insults about "We invented it first!" and "My Huo Che/Hwacha is better than yours!"

The debate is completely pointless. Nevertheless, I will attempt to track down the earliest historical references to Huo Che and Hwacha, and hopefully clear up the confusion.

The first recorded use of Ming Dynasty Huo Che occurred in 1401 AD, during the last phase of Jing Nan Campaign. Since no detailed description of Jing Nan Campaign Huo Che can be found, this cannot be considered a definitive proof. The first unequivocal record of a Ming rocket cart can be traced to 1449 AD.

On the other hand, the first Korean Hwacha was developed in 1409 AD, only seven years after the conclusion of Jing Nan Campaign. However, early Hwacha was actually a gun-mounted cart designed to shoot unpowered darts, which obviously did not qualify as a multiple rocket launcher. In fact, rocket-launching Hwacha was a much later development only introduced in 1451 AD, three years after the perfection of Shingijeon (신기전 or 神機箭) rocket.

Verdict: Chinese invented the world's first rocket cart/vehicle-mounted multiple rocket launcher, although they only beat the Koreans to it by a mere two years.
