US Army orders M1061 cartridges
Day and Zimmerman is to manufacture M1061 high-explosive cartridges for 60mm mortars, under a $92.7 million contract modification from the US Army.
Work will be performed in Parsons, Kansas, with an estimated completion date of 27 September 2021.
The M1061 was originally developed by Orbital ATK (now Northrop Grumman Innovation Systems), Saab Bofors Dynamics Switzerland, and the US Army Armament Research, Development and Engineering Center at the Picatinny Arsenal, New Jersey.
The cartridge was developed to increase the effectiveness of the 60mm mortar while improving its insensitive munitions characteristics. The increase in lethality (to near 81mm lethality) was accomplished by utilising a matrix comprised of pre-formed fragments and PBXN-110 explosive.
