Rheinmetall recently revealed a new 120m HE round to a group of international experts at its proving ground in Unterlüß, Germany. It can be fired from any in-service 120mm smoothbore gun (L44 and L55). Dubbed the DM11, the new ammunition was developed on behalf of the German Ministry of Defence. It enables main battle tanks to respond more effectively to a variety of contemporary threats.
From the technical standpoint, the HE DM11 stands out in two ways: it is programmable when loaded and features an airburst detonation capability.
Modularly designed, the 120mm x 570 HE Temp DM11 consists of an IHE (Insensitive High Explosive) warhead with a programmable fuse and ballistic cap, a tail unit, driving band, a combustible case with a propelling charge, a newly designed stub case with primer and an integrated data link cable for programming.
Interfaces between the propulsion system and the warhead and between the propulsion system and the fuse ensure that the propulsion system can be exchanged once its service life expires; it will also be possible to exchange the fuse in future at reasonable cost. A further unique feature of the DM11 is that it safe to fire in all climate zones (-46oC to + 71oC).
The HE DM11 is principally used for engaging non-armoured and lightly armoured vehicles, antitank positions (both dug-in and in the open) and field fortifications.
Furthermore, it can be employed – thanks in part to its high precision and long range – for penetrating walls and taking out targets in buildings, as well as for creating breaches and avenues of approach in built-up areas to support dismounted troops.
