Some seemingly marginal projects may grow into unexpected international success. One of these was the development of the Cactus anti-aircraft system, which was ordered from the French company Thomson by the South African government. Although it was a foreign order, the system gradually came under the designation Crotale into the armament of the French Armed Forces.
Originally a foreign order, a relatively successful anti-aircraft system emerged, which has found a number of customers around the world. But over the years, significant progress has been made in the field of electronics and miniaturization. Therefore, it was appropriate to develop a more modern version, corresponding to current requirements. Before that, let's look at an upgrade made in China.
