AHS Krab - a currently developed Polish project of a 155 mm self-propelled howitzer (a barrel length of 52 caliber).
The weapon was initially built on the basis of the modernized UPG-NG chassis by OBRUM manufactured by Zakłady Mechaniczne Bumar-Łabędy and the licensed British AS90 / 52 turret system.
In December 2014, a decision was made to replace the faulty UPG-NG undercarriage with the Samsung Techwin licensee used in the K9 Thunder cannon.
