It is estimated that an APRA-40 can saturate one hectare of land with a single discharge of 40 rockets. The Romanian Army keeps about 130 vehicles in service. The reloading of the 40 tubes takes about 6 minutes and the full salvo goes off in about 30 seconds. The APRA-40 can leave the position after the firing in just under 2 minutes. Iraq maintains about 50 APRA-40 in service, but with a Volvo truck as transport-launcher vehicle instead of the Romanian DAC model. The system can be fired remotely, using a 50 meters long cable.
