Development

PZL-Mielec, then known as "WSK-Mielec", began to design the Dromader in the mid 1970s, with help of United States airplane manufacturer Rockwell International. PZL Swidnik asked for Rockwell's help because of the political situation at the time: operating in an Eastern Bloc country, PZL wanted the airplane to sell well worldwide, and the company realized that FAA certification would be important in reaching that goal. Rockwell on the other hand wanted to fit Polish high-power radial engines into its agricultural planes. This co-operation meant that the Dromader shares outer wing panels and part of hull with the Rockwell Thrush Commander.

The first prototype of the airplane flew on August 27 1976. In September 1978, the airplane was given certification to fly in Poland. Certifications from many countries around the world followed soon.

Many airplanes of the M-18 type and its variations can still be seen around the world flying as cropdusters. They are a very common sight, for example, when driving by the Sonora Desert, as cropdusting and firefighting airplanes are necessary in middle and south Arizona as well as in northern Mexico.

Most Dromaders are easy to distinguish because of their yellow color. Over 700 had been built by 2002. Currently (2004) models M-18B and M-18BS are offered by PZL-Mielec.
