The Korean Smart Top-Attack Munition (KSTAM)[1][2][3] is a smart munition intended to be launched from the gun of a main battle tank, namely the South Korean K2 Black Panther. Comparable systems include Diehl Corporation's Spear, DRDO SAMHO, CMI Defence and Luch Falarick 120, Israeli Aerospace Industries LAHAT, Nexter Systems Polynege, Alliant Techsystems STAFF and MRM-KE, Raytheon Technologies MRM-CE, and the two final companies' TERM.[1]
There are two variations of KSTAM. KSTAM-I and KSTAM-II. KSTAM-I is modeled after IMI's 105 mm Excalibur top-attack munition, while KSTAM-II is modeled after SMArt 155's Sensor Fuzed Smart Munition (SFSM) developed by Diehl. While the two systems significantly differ from one another, their concept remains the same to defeat enemy armor by attacking their most vulnerable spot, the top.[1]
