Remote Anti-Armor Mine System

The Remote Anti-Armor Mine System (RAAMS) are two types of 155mm howitzer projectiles containing nine anti-tank mines each: the M718 or M718A1 (RAAM-L) with a self-destruct time over 24 hours and the M741 or M741A1 (RAAM-S) with a self-destruct time under 24 hours. Both projectiles are used with the M577 or M577A1 Mechanical Time and Superquick (MTSQ) fuze, which triggers the ejection mechanism of the mines above enemy territory after a preset time.[2]

Development of RAAMS dates to around 1980.[1]

These mines can be delivered at ranges from 4 to 17.6 kilometres (2.5 to 10.9 mi) from the artillery battery position using either the M109 series or M198 or M777 series howitzers.[3]

By January 2023, the US had sent approximately 10,200 rounds to Ukraine since the start of the Russian invasion of Ukraine in February 2022. [4][5][6]
