Depending on the ammunition and charges, the standard version can attain ranges of up 3,200 metres. Equipped with a thirty centimetre-longer barrel, the range increases by around 500 metres. The commando variant of the RSG60 has a range of around 2,000 metres.
About 70 centimetres long, the barrel is made of steel with a carbon fibre over-wrap. This assures the necessary stability at the same time as lower weight, resulting in a barrel that weighs around 30 percent less than a conventional steel mortar. The base plate is made of carbon fibre composite material. The novel design of this indirect fire weapon not only saves space, it can be set up and ready to fire in a matter of seconds. Furthermore, by loosening the retaining bolts, it is possible to separate the RSG60 from the base plate in around thirty seconds, transforming it into lighter-weight commando mortar.
Development of the new mortar began in October 2017 at Rheinmetall Waffe Munition. Rheinmetall's objective was to augment the Group's versatile family of 60mm ammunition and existing Rheinmetall Electronics fire control technology with a matching, future-oriented weapon system. Right from the start, development work therefore focused on low weight, speed and ergonomics.
The RSG60 has repeatedly undergone successful test firing.
