Soldiers engage in grenade training. The hand grenade is familiar to the general public by virtue of its frequent appearance in countless war movies. Yet the basic technology is almost 100 years old. A Picatinny arsenal engineer wants to give a modern face-lift to the warhorse of warfare.
PICATINNY ARSENAL, N.J. — As far as the design of the basic hand grenade goes, essentially it has been frozen in time.
The first pull-pin design with a lever and delayed fuze dates back to May 1915 and is often referred to as the grandfather to the current variation.
“The basic technology is almost 100 years old,” said Richard Lauch, a Picatinny Arsenal engineer, referring to the Mills Bomb No. 5.
The Mills bomb is the popular name for a series of prominent British hand grenades. They were the first modern fragmentation grenades and named after William Mills, a hand grenade designer.
Lauch, who served in the U.S. Marine Corps, has been on a mission to modernize the hand grenade so that it is safer as well as easier to use and cheaper to produce.
During the last year and half of his Marine service, Lauch was primary marksmanship instructor in the Weapons Training Battalion at Marine Corps Recruit Depot, San Diego, Calif.
While he was assisting in training recruits on the proper use of the M67 hand grenade, Lauch became intimately familiar with what he saw as the grenade’s deficiencies.
The current grenade fuze design only allows for a right-handed user to throw it in the upright position. A lefty has to hold the grenade upside down to safely pull the pin.
Also, the current fuze consists of an explosive train that is in-line from production through usage; thus, it is always “armed.”
