Among the latest developments in this field is the Oto Melara Vulcano subcalibre 155 mm ammunition, the laser version of which is being developed together with Diehl Defence.
The effort is company-funded, but Rheinmetall is currently looking for partners particularly for the development of ad-hoc charges and munitions, including full-calibre and subcalibre types.
The latter is able to defeat heavily armoured targets (700 to 750 mm penetration capability) at a range of 5500 metres, and a 30 mm automatic gun firing Kerner armour-piercing subcalibre rounds completes the armament.
It so happens that barrel insert systems (Bis) and subcalibre devices can both overcome the more severe of firing range limitations and achieve cost savings in terms of ammunition.
For the last two, a 20 mm Inbore Subcalibre Training Device (ISTD) has been designed for use with guns with an electrical firing mechanism, and can be quickly inserted into the barrel of the tank's gun.
Clearly the subcalibre concept is not limited to main battle tank guns.
The use of a subcalibre mortar training system such as that developed by Nico-Pyrotechnik makes for substantial cost savings while enabling crews to practice the use of mortars.
Oerlikon has recently embarked on the development of a family of subcalibre ammunition, which offers a decreased time of flight (and hence a higher hit probability against a moving target), combined with a high velocity at impact.
Although clearly less ambitious than the Swiss subcalibre family in ballistic performance terms, these Norwegian MP rounds are noteworthy for their high reliability and long shelf-life, resulting primarily from a pyrotechnic fuze train.
