Who manufactures the M67 grenade?
The M67 has been manufactured by at least three distinct
companies, each of whom utilize unique markings to distinguish
their product.
"JA" marked M67s were manufactured by the Joliet Army Ammunition
Plant, located just south of Joliet, Illinois. Production of the JA
M67 took place at the Kankakee facility of the JAAP (previously
known as the Kankakee Ordnance Works) during the Vietnam War,
ending sometime in the late 1970s. The JAAP no longer manufactures
live-ordnance.
"LS" M67s were manufactured by the Lone Star Ordnance Plant of
Texarkana, Texas, a contractor-operated facility previously run by
the Goodrich Corporation (former B.F. Goodrich Rubber Corporation)
under the auspices of a defense contract. LS M67s were produced
throughout the Vietnam War and, perhaps, well after; however, the
LSOP has since been deactivated (as of 2009) courtesy of the 2005
BRAC (Base Realignment and Closure) issued by the United States
Department of Defense.
"MA" M67s were/are manufactured by the Milan Army Ammunition
Plants (composed of what was, originally, the Milan Ordnance Depot
and Wolf Creek Ordnance Plant), located adjacent to Milan,
Tennessee. The MLAAP is a member of the United States Army Materiel
Command (AMC), whose purpose is the assembly, packaging and storage
of conventional ammunition exclusively for military use and, as
such, is the sole former-manufacturer of the M67 still in business
today.
It's probable that other groups have also created the M67 over
its service lifespan, however, I've no records to indicate
such.
