energy (product of acceleration and time) is not sensed throughout the arming distance. Upon
impact, the firing pin body walls are crushed between the target and the oncoming fuze body. The
firing pin contained in the firing pin body then impacts the oncoming S&A mechanism within the
fuze body, initiating the explosive train. The explosive consists of the M104 primer, M85
detonator, lead, booster and warhead explosive which are initiated in sequential order. The M423
is used for launch from low speed aircraft. The M427 is a variation used for launch from high
speed aircraft and requires 180 to 426 meters rocket travel to arm. The PD fuzes do not require
an umbilical connection to the launcher.

an integral fuze, 9 submunitions, and an expulsion charge assembly. The nose cone assembly, a
of 80% M10 double base propellant and 20% Class 6 black powder. The expulsion charge is
stack of submunitions through the nose cone.
The primary cargo warhead fuze is the M439 Fuze. It is a resistance-capacitance electronic
variable time delay fuze. The time delay is remotely set for the desired functioning distance (time)
by charging the circuit from the fire control center, providing a variable range of 0.5 to 7.2
kilometers. The fuze does not have an internal battery; instead energy is supplied from by the
aircraft setter at the time of fuze setting. The energy is stored in a capacitor and will operate the
electronic timer and fire the M84 electronic detonator. The charging cycle takes place
approximately 50 milliseconds prior to rocket motor firing. The fuze begins timing at the first
motion of the rocket and will function at the prescribed time if the Safety and Arming (S&A)
device is armed. The S&A mechanism also prevents the fuze from being charged if it is in the
partially-armed or fully-armed position. The S&A is a mechanical acceleration integrator with an
unbalanced rotor holding the M84 electric detonator and a runaway escapement. An acceleration
greater than 27G is necessary to arm the fuze. The M439 Fuze is a base mounted, forward firing
fuze. The fuze connector cable extends from the fuze, through the warhead in a lengthwise
channel, and exits the ogive for connection to the launcher by an umbilical connector.
The HE, MPSM M73 Grenade consists of a steel body with a fragmenting wall filled with
Composition B explosive incorporating a shaped charge liner, LX14 booster, explosive lead
charge, M230 omnidirectional fuze with M55 detonator, wave shaper, and fabric drag device
(RAD). The fragmenting body produces 10 grain fragments with a maximum velocity of
approximately 5,000 feet per second. The shaped charge sprays lethal fragments nearly horizontal
360 degrees. The submunitions consistently impact within a 40-meter radius of each other.
Submunition self destruct has not been a consideration. EOD procedures obviate the need for self
destruct. Lethality (penetration) is classified and can be made available through licensed
agreement. The performance is roughly a 70 percent (SMCAR-CCH-A Memorandum, 23 Jun
1988) increase in lethal area over the M151.

Except for the illuminent, the M278 is identical to the M257 warhead. At the aft end of the
Separation and Drogue Assembly is the Motor Adapter which is the threaded interface for the
launch rocket motor. Inside the adapter is the M442 fuze which initiates the firing sequence for
the M278 flare. The fuze must sense an acceleration of at least 17-22 G for about 1 second prior
to arming. Upon deceleration of the burnt-out rocket motor the armed fuze fires, directing its
output into a 9-second pyrotechnic delay column which in turn ignites a separation charge. The
separation charge produces a rapid increase in pressure inside the motor adapter which is reacted
by a pusher plate on top of the Drogue Housing. This shears 12 holding pins that are evenly
spaced around the circumference of the joint. The pressure also provides an accelerating force for
the flare and a decelerating force for the launching rocket motor with the Motor Adapter
attached. This ensures positive separation for the flare, and a Deflector plate pulls the expended
motor out of the flare flight path. When the Pusher Plate falls into the airstream it pulls the
Drogue Chute out of the aft end of the Drogue Housing. Attached to the shroud line bridle of the
