The SG-155/10 ("Self-propelled Gun, 155mm, Year 2010"), is a Berusian 155 mm turreted self-propelled howitzer based on the MBT-100's hull, developed by Nirvash Tecnica International (NTI) and BMS for the Berusian Army.
The SG-155/10 is one of the most powerful conventional artillery systems deployed in the 2010s.
It is capable of a very high rate of fire; in burst mode it can fire five rounds in nine seconds, fourteen rounds in 56 seconds, and can — depending on barrel heating — fire between 10 and 16 rounds per minute continuously.
The system has automatic support for up to 8 rounds of Multiple Rounds Simultaneous Impact (MRSI). The replenishment of shells is automated. Two operators can load 80 shells and propelling charges in less than 8 minutes.
Upgrades to the cannon, ammunition, fire control, survivability, and other electronics systems over the design's lifespan have expanded the system's capabilities, including tactical nuclear projectiles, Cannon Launched Guided Projectiles (CLGP or Copperhead), Rocket Assisted Projectile (RAP), FAmily of SCAtterable Mines (FASCAM), and improved conventional munitions (the Dual-Purpose Improved Conventional Munition, DPICM).
