with the rockets are covered in otherpublications.
1.2 SCOPE.
1.2.1 For each item of materiel, there are illustrations
anddescriptions together with characteristics and related
data.Included in the related data are type classification,
logisticscontrol code (LCC), dimensions, weight, performance
data,packing data, and shipping and storage data.
1.2.2 Information concerning supply, operation, andmaintenance
of the items will be found in the publicationsreferenced for those
items. A complete listing of these pub-lications is maintained in
DA PAM 25-30.
1.2.3 Within this manual, items with the following
typeclassifications are included:
1.2.3.1 Standard (LCC-A, LCC-B) OTCM/AMCTCM.
1.2.3.2 Contingency (CON).
1.2.3.3 Limited Procurement (LP).
1.2.3.4 Reclassified obsolete (OBS) for regular Armyuse, but
used by National Guard or Reserve Units.
1.2.3.5 Reclassified OBS for all Army use, but used byMarine
Corps, Air Force, or Navy.
1.2.3.6 Reclassified OBS, no users, but U.S. stocksremain.

notincluded: Reclassified OBS for all U.S. use. No U.S.
stocksremain. (Foreign use or stock may remain.)
1.2.5 Numerical values, such as weights, dimensions,candlepower,
etc., are nominal values, except when specifiedas maximum or
minimum. Actual items may vary slightlyfrom these values. Allowable
limits can be obtained fromthe drawings indicated in the data
sheets.
1.3 QUANTITY-DISTANCE CLASSES AND STOR-AGE COMPATIBILITY
GROUPS.
Quantity-Distance (QD) classes and Storage CompatibilityGroups
(SCG) listed in this manual are changed. For con-version to new
system see table 1-1.
Notes:
1/New QD and SCGs are compatible with classes used byNATO
nations.
2/Numbers in parentheses are minimum distances x 100 feetto
protect against specific fragment hazards and vary withitems and
types of ammunition. (Refer to AR 385-64 andDA PAM 385-64.)
3/There is no simple conversion from old SCGs to new sys-tem.
The SCG groups listed in this column are typical forthe majority of
items in the corresponding listed QD classbut do not apply to every
individual item in the class. ForSCG of individual items refer to
AR 385-64 and DA PAM385-64.

ROCKET, HIGH-EXPLOSIVE, 3.5-INCH: AT, M28A2
Type Classification:
STD (LCC-B) OTCM 36841 Jul 58
Use:
The M28A2 HEAT rocket is usedprimarily against armored
targets,tanks and secondary targets, such asgun emplacements,
pillboxes and per-sonnel. It is capable of penetratingheavy armor
at angles of impact greaterthan 30°. In an antipersonnel role,
ithas a fragmentation area 10 yd wide and20 yd deep.
Description:
a. The warhead is cylindrical andtapered. The forward end,
called theogive, is thin metal and hollow. Therear end, threaded
internally to receivethe fuze which is encircled by a safefyband.
The warhead contains a copper
cone whose apex faces aft and acts to shapethe high explosive
charge Composition B -
(Comp B).
b . The base detonating (BD) rocketfuze M404A2 consists of a
body which con-tains the functioning parts; a safety band,a
detonator and a booster pellet. The fuzebody and safety band are
olive drab. Thefuze mechanism consists of an activatingplunger, a
setback spring, a setbacksleeve, a firing pin assembly, a detent
spring, an ejection pin and an ejectionspring. The spring-loaded
ejection pinpasses through the fuze body.
c . The motor assembly consists ofa tube which houses the
propellant andigniter. The fin assembly is securely at-tached to
this tube. The front end of thetube is assembled to the base of the
fuze.The rear end forms a nozzle. The cylin-drical motor cavity is
divided into four
2 - 3
-
TM 43-0001-30
sections by two spacer plates which sup-port the grains of
propellant powder.
d . Each grain of propellant is5-in. long and approximately
3/8-in. indiameter. Three grains are placed ineach of the four
sections formed by thespacer plates. Each lot of propellant
isadjusted at the time of manufacture togive standard velocity. The
igniter ig-nites the propellant.
e . The igniter consists of a short,cylindrical plastic case
containing asmall black powder charge and an elec-trical squib. It
is assembled in the for-ward end of the motor on top of the
pro-pellant, spacer plates. The leads of theelectrical squib,
running parallel to thegrains of propellant, pass from the ig-niter
through the nozzle into the expan-sion cone. A green lead (ground)
wireis connected to the aluminum supportring of the contact ring
assembly. Ared lead (positive) wire is attached to apin which is
insulated from the supportring, but is in contact with the
coppercontact band. These connections arepositioned 180° apart.
Blue lead is usedfor test purpose only.
f . The fin assembly consists of sixaluminum alloy fins and a
contact ringassembly. The contact ring assembly,which encircles the
fins, consists ofthree rings. The aluminum support ring,which is
innermost, is separated fromthe copper contact ring by a plastic
in-sulating ring, The fins are spot weldedto the expansion cone,
and the expansioncone is press fitted to the rear of themotor tube.
The M24 and the M66 off-route mines utilizing M28A2 HEATrockets are
described in TM 43-0001-36.
Differences between Models:
The BD rocket fuze M404A1 is similarto BD rocket fuze M404A2.
The M404A1differs principally in minor design changesof the
functioning parts and the shape of thesafety band.
Functioning:
a . When the safety band is removed,the ejection pin moves
outward approxi-mately 3/8 of an inch but still prevents allparts
of the fuze mechanism from moving.When the rocket is in the firing
chamber,the ejection pin is partially depressed bythe chamber,
thereby freeing the setbacksleeve so it can move to the rear when
therocket is fired. The fuze is still safe,since the ejection pin
prevents movementof the actuating sleeve and firing pin.
b. If it becomes necessary to removethe rocket from the
launcher, the ejectionpin will move outward and re-engage
thesetback sleeve. This returns the fuze toits original safe
condition.
c_. When the rocket is fired, the forceof inertia causes the
setback sleeve to moverearward. It is held in its rearward
posi-tion by the lockpin. When the rocket leavesthe muzzle of the
launcher, the ejection pinis thrown clear of the fuze by the
ejectionpin spring. The fuze is then fully armed.
d. During flight, tie firing pin leverand firing pin spring
prevent the firing pinfrom striking the detonator, The creepspring
retards the forward movement ofthe plunger and actuating sleeve.
The ac-tion of the creep spring prevents the fuzefrom firing should
the rocket strike lightobjects such as thin brush or
undergrowth.
2 - 4
-
TM 43-0001-30
e . Upon impact with a more resis-tant object, the plunger and
actuatingsleeve move forward until the sleeve hitsthe firing pin
lever. This causes thefiring pin to strike and detonate the
war-head.

a . The warhead is completely inert.The practice rockets can be
fired at buttoned-up, modified target tanks without danger totank
crews. The practice rockets have thesame flight characteristics as
the HEATrocket.
b. The dummy fuze rocket M405 whichseries as a coupling for the
warhead andmotor, is cylindrical. It is threaded exter-nally at the
forward end to fit into the
warhead assembly, and internally at therear end to receive the
motor assembly.A safety band fits around the seals andfuze. This
fuze incorporates a double-locking, bore-riding, round ejection
pinassembly simulating that used in basedetonating (BD) fuze
M404A2. The body ofthe fuze and the safety band are
paintedblue.
c_. The motor assembly consists of atube which houses the
propellant and ig-niter, The fin assembly is securelyattached to
this tube. The front end of thetube is assembled to the base of the
fuze.The rear end forms a nozzle. The cylin-drical motor cavity is
divided into foursections by two spacer plates which sup-port the
grains of propellant powder.
d. Each grain of propellant is 5-in.long and approximately
3/8-in. in

diameter. Three grains are placed in eachof the four sections
formed by the spacerplates. Each lot of propellant is adjusted
atthe time of manufacture to give standardvelocity. The igniter
ignites the propellant.
e. The igniter consists of a short, cyl-indrical plastic case
containing a smallblack powder charge and an electrical squib.It is
assembled in the forward end of themotor on top of the propellant
spacer plates.The leads of the electrical squib, runningparallel to
the grains of propellant, passfrom the igniter through the nozzle
into theexpansion cone. A green lead (ground) wireis connected to
the aluminum support ring ofthe contact ring assembly. A red
lead(positive) wire is attached to a pin which isinsulated from the
support ring, but is incontact with the copper contact band.
Theseconnections are positioned 180° apart. Bluelead is used for
test purpose only.
f. The fin assembly consists of sixaluminum alloy fins and a
contact ringassembly. The contact ring assembly,which encircles the
fins, consists of threerings. An aluminum support ring, which
isinnermost, is separated from the coppercontact ring by a plastic
insulating ring. Thefins are spot welded to the expansion cone;the
expansion cone is press-fitted to therear of the motor tube.
Differences between Models:
a. The M29A1 and M29A2 rockets aresimilar in appearance to the
M28A2. TheM29 series differ in that they have a crimp-ing groove at
the juncture of the warheadbody and ogive. The rockets of an
earlymanufacture are assembled with M28A2rocket warhead metal parts
inert loaded withplaster of paris.
b. The M29A1 warhead differs from theM29A2 warhead in the head
and trap and
spacer assembly. The ogive is attachedto the head body of four
screws staked tothe ogive. Some rockets may have the casttrap and
square spacer blades.
The warhead being inert, no functionsoccur when the rocket is
fired. The rocketis strictly for training purpose.

ROCKET, GROUND: 3.5-INCH SMOKE (WP) M30
Type Classification:
(obsolete) was AMCTCM STD (LCC-B)36841 Jul 58
Use:
The 3.5-in. whiteM30 smoke rocket isscreening purposes.
Description:
phosphorous (WP),intended for smoke
a. Smoke rocket, 3.5-in. WP, M30 isfired in the same manner as
rocket M28A2.On impact, the rocket bursts to produce aspray of
phosphorous particles. Theseignite on contact with air, generating
densewhite smoke. The smoke itself is harmless,but the burning
particles produce painfulburns. In external contour, the rocket
issimilar to the M28A2. Rocket M30 consists
of the WP smoke warhead, base detonating(BD) fuze M404A1 or
M404A2, and theservice motor assembly.
b. Rocket fuze BD M404A2 consistsof a body which contains the
functioningparts; a safety band, a detonator and abooster pellet.
The fuze body and safetyband are olive drab. The fuze
mechanismconsists of an activating plunger, a set-back spring, a
setback sleeve, a firing pinassembly, a detent spring, an ejection
pinand an ejection spring. The spring-loadedejection pin passes
th-rough the fuze body.
c. The motor assembly consists of atube which houses the
propellant and ig-niter. The fin assembly is securelyattached to
this tube. The front end of thetube is assembled to the base of the
fuze,The rear end forms a nozzle. The cylin-drical motor cavity is
divided into four

-
TM 43-0001-30
sections by two spacer plates which supportthe grains of
propellant powder.
d. Each grain of propellant is 5-in. longand approximately
3/8-in. in diameter.Three grains are placed in each of the
foursections formed by the spacer plates. Eachlot of propellant is
adjusted at the time ofmanufacture to give standard velocity.
Theigniter ignites the propellant.
e. The igniter consists of a short, cyl-indrical plastic case
containing a smallblack powder charge and an electrical squib.It is
assembled in the forward end of themotor on top of the propellant
spacer plates.The leads of the electrical squib, runningparallel to
the grains of propellant, passfrom the igniter through the nozzle
into theexpansion cone. A green lead (ground) wireis connected to
the aluminum support ring ofthe contact ring assembly. A red lead
(posi-tive) wire is attached to a pin which is insul-ated from the
support ring, but is in contactwith the copper contact band. These
con-nections are positioned 180° apart. Bluelead is used for test
purpose only.
f. The fin assembly consists of sixaluminum alloy fins and a
contact ringassembly. The contact ring assembly,which encircles the
fins, consists of threerings. An aluminum support ring, which
isinnermost, is separated from the coppercontact ring by a plastic
insulating ring.The fins are spot welded to the expansioncone, and
the expansion cone is press fittedto the rear of the motor
tube.
Differences between Models:
a. This warhead is generally similar tothat of rocket M28A2,
except that it has acharge of white phosphorous (WP). At therear,
it has a union internally threaded toreceive the fuze. The burster
casing (M8)
is press-fitted into the union, and the steelbody is fitted over
it. The steel ogive andthe internal steel dome, which closes
theforward end of the filler cavity are at-tached to the body.
b. This fuze is similar to BD rocketfuze M404A2. The M404A1
differs princi-pally in minor design changes of the func-tioning
parts and the shape of the safetyband.
Functioning:
a. When the safety band is removed,the injection pin moves
outward approxi-mately 3/8 of an inch but still prevents allparts
of the fuze mechanism from moving.When the rocket is in the firing
chamber,the ejection pin is partially depressed bythe chamber,
thereby freeing the setbacksleeve so it can move to the rear when
therocket is fired.
b . The fuze is still safe, since theejection pin prevents
movement of theactuating sleeve and firing pin.
c. If it becomes necessary to removethe rocket from the
launcher, the ejectionpin will move outward and re-engage
thesetback sleeve. This returns the fuze toits original safe
condition.
d. When the rocket is fired, the forceof inertia causes the
setback sleeve tomove rearward, It is held in its rearwardposition
by the lockpin. When the rocketleaves the muzzle of the launcher,
theejection pin is thrown clear of the fuze bythe ejection pin
spring. The fuze is thenfully armed.
e . During flight, the firing pin leverand firing pin spring
prevent the firing pinfrom striking the detonator. The creep
2 - 1 2
-
TM 43-0001-30
spring retards the forward movement of theplunger and actuating
sleeve. The action ofthe creep spring prevents the fuze fromfiring
should the rocket strike light objectssuch as thin brush or
undergrowth.
f . Upon impact with a more resistantobject, the plunger and
actuating sleevemove forward until the sleeve hits the firingpin
lever. This causes the firing pin tostrike and detonate the
burster.

147)at the 100 and 150 metermarks. On the weapons withthis limited
light sight the100 and 150 meter marks arewhite, the remaining
markingsare red. On weapons withoutthis feature, all markingson the
sight are in red.The M72A3 series weapons donot have this
radioactivesight feature.
b. After the trigger safety handleis released, the trigger is
depressed.This releases the channel assembly whichdrives the firing
pin into the primerof the rocket motor igniter. Thisignites the
black powder in the flashtube, which in turn, ignites the
integraligniter of the rocket motor. The igniterinitiates the
propellant. The burningpropellant propels the rocket from
thelauncher.
c. Upon target impact, the fuze traindetonates the charge which
collapses thecopper liner into a finger shaped jet.The jet is
preceded by extremely hot,high velocity gases which melt a hole
inthe target. The copper jet thenpenetrates into the target.
Almostsimultaneously the body and ogive areblasted into small
fragments by thedetonated octol charge. These fragmentstravel
adjacent to, and aft of the lineof fire.

Use:
The M74 incendiary thickenedtriethylaluminum (TPA) is used
todefeat or neutralize hard, soft,or jungle
targets.Description:
The M74 consists of a rocket warheadcontaining approximately 1.3
pounds ofTPA, a base detonating (BD) fuze
Functioning:
When the projectile is fired, accelera-tion acts upon the fuze
sequential leafarming mechanism. The fuze rotorassembly is then
free to rotate to thearmed position. When the rotor is inthe armed
position, the detonator isalined with the remainder of the
explo-sive train. Rocket deceleration, dueto impact, causes the
graze elementof the fuze to shift, thereby allowingthe firing pin
of the fuze to be driveninto the primer. The primer flashesthrough
the flash channel and initiates
and an adapter which adapts the rocket motor the detonator, then
the trademark into the warhead. The rockets are issued in the
warhead; disseminating the warheadfour round clips. agent.

ROCKET, PRACTICE, 35 MM, SUBCALIBER, M73
Type Classification:
STD (LCC-A) AMCTCM 7617 April 70
Use:
To train personnel in the operation anduse of the 66-mm antitank
rocket, M72series.
Description:
a. The M190 subcaliber launcher withM73 subcaliber rocket can be
used againstall solid stationary or moving targets.
Together they can be used in all trainingphases, from fixed
firing live to simulatedsituations, such as a “trainfire”
typeoperation.
b_ . The M190 subcaliber launcher isa tubular, telescoping,
smooth-bore, open-breech weapon.
c_ . The M73 subcaliber rocket consistsof a spotting head, a
motor closure, arocket motor and an igniter assembly. Thespotting
head contains the same flash com-position used in the M80 explosive
simula-
tor (TM 9-1370-203-34&P) to assist in locating
2 - 2 3
-
TM 43-0001-30
the fired rocket. The forward end of themotor closure provides a
cavity that con-tains a base detonating fuze and a primer.The motor
case contains tubular grainsor propellant. The rocket is stabilized
bysix molded, plastic fins.
Differences between Models:
The external appearance of the M190subcaliber is almost
identical to theM72A1. The M190 differs from the tacti-cal launcher
M72A1 by having a subcaliberrocket and a quick release primer
housingdoor to simplify reloading. The usedM72A1 launcher is
modified by use of aconversion kit to produce the M190 sub-caliber
launcher.
Functioning:
Extending the launcher into the extendedor firing position
automatically locks theweapon. After the trigger safety handle
isreleased, the trigger can be depressed.This releases the channel
assembly whichdrives the firing pin into the primer of therocket
motor igniter. This ignites theblack powder in the flash tube,
which, inturn, ignites the integral igniter of therocket motor. The
igniter initiates thepropellant. The burning propellant propelsthe
rocket from the launcher. When thespotting head of the rocket
strikes a target,an inertia-driven firing pin sets off theprimer.
The primer in turn sets off thespotting head which produces a
flash, noiseand white smoke.

d . The rocket motor is described inChapter 5.
Differences between Models:
The Mk 40 Mods 1 and 3 have integralbulkhead motor tubes whereas
the Mk 40Mod 0 has nonintegral bulkhead tube. Theigniter of the Mod
3 motor differs fromthat of the Mods 0 and 1 motors in that
theigniter has been modified to incorporate acarried, frangible
case in lieu of the blow-out plug. Also, the squib is located on
theperiphery instead of the center of the case.
Functioning:
a. The rocket motor functions whencurrent passes through the
launcher firingcontact to the igniter in the rocket motor.This
current generates the heat necessaryto initiate the igniter charge
which ignitesthe propellant grain. Combustion gasesfrom the burning
propellant pressurizes thechamber and exhaust through the
nozzle,providing the unequal forces required forrocket thrust.
b. Functioning of the fuze sets off anexpelling charge which
forces the pusherplate, flechettes and semicylindricalsleeves
forward. This shears the pinsattaching the nose cone to the body
and ex-pels the flechettes into the slipstreamahead of the
rocket.

USE:
The M255A1 warhead contains approximately 1179 60-grain
flechettes for use against light material targets and
per-sonnel.
DESCRIPTION:
The complete round consists of a warhead with an integralfuze
and a rocket motor. The warhead consists of a nosecone assembly, a
warhead case, and integral fuze, approxi-mately 1179 60-grain
flechettes, and an expulsion chargeassembly. The nose cone
assembly, a plastic cone bonded toa metal cup-shaped base, is
attached to the body by shearpins. The body is a hollow cylinder
loaded with approxi-mately 1179 60-grain flechettes. A metal pusher
plate islocated just aft of the flechette cargo stack and is
forward ofthe expulsion charge assembly. The threaded end of
thebody is machined internally to accommodate a base-detonat-ing,
remote settable, variable range fuze.
The primary warhead fuze, M439 RC, is a resistance-capaci-tance
electronic variable time delay fuze. The time delay isremotely set
for the desired functioning distance (time) bycharging the circuit
from the fire control center. The fuzebegins timing at the first
motion of the rocket and will func-tion at the prescribed time if
the Safety and Arming Device(S&A) is armed. The S&A is a
mechanical accelerationintegrator with an unbalanced rotor holding
the M84 electricdetonator and a runaway escapement. An
accelerationgreater the 27G is necessary to arm the fuze. The M439
RCfuze is a base mounted, forward firing fuze. The fuze con-nector
cable extends from the fuze, through the warhead (ina lengthwise
groove), and exits the ogive for connection tothe launcher by an
unbilical cable.
The flechette cargo contains approximately 1179
60-grainflechettes, which are deployed by initiation of a 5.5
gramexpulsion charge.
The spin-stabilized wrap-around fin aircraft rocket is an
air-to-ground rocket primarily deployed from rotary-wing andother
low-speed aircraft. It can also be used on Air Forceand Navy jet
aircraft, as well as in the Mobile GroundLauncher System.

TM 43-0001-30
FUNCTIONING:
The rocket motor functions when current passes through
thelauncher firing contact to the igniter in the rocket motor.The
current generates the heat necessary to detonate theigniter charge
which ignites the propellant grain. Combus-tion gases from the
burning propellant pressurize the cham-ber and exhaust through the
nozzle, providing the unequalforces required for rocket thrust.
Upon receipt of the fire signal from the pilot, the remote
fuzesetter processes the proper time constant (delay) to the M439RC
electronic time fuze immediately prior to firing therocket. The
intervalometer delivers a 160 millisecond pulseinterval. The pulse
is divided into a 45 millisecond fuzecharging pulse, followed by a
45 millisecond rocket firingpulse. The remaining 70 milliseconds
are used as dwellinterval to maintain spacing between pairs of
rockets fired.
After the rocket is fired and experiences sustained
accelera-tion, the setback weight of the S&A device within the
fuzemoves rearward sufficiently to allow the roller attached tothe
unbalanced rotor to move out of the groove provided bythe setback
weight. Once the roller is free, the unbalancedrotor rotates in
response to the acceleration forces. The rota-tion of the rotor is
delayed by a runaway escapement whichprovides an arming delay (a
function of the acceleration)until the rocket is a safe distance
from the aircraft. When thesetback weight experiences the necessary
magnitude ofacceleration, the rotor will lock up with the
propellant chargeand the fuze is armed. The detonator is now
connected to thefiring circuit, the connection between the
electronic moduleand the umbilical cable is broken, and electronic
timing isstarted.
From 1.2 to 25 or more seconds after firing, depending uponthe
range setting, the detonator is initiated electrically andignites
the expelling charge. Gases from the expellingcharge force the
pusher plate and cargo stack forward, shear-ing the nose cone
(ogive) retaining pins and ejecting theflechettes into the
airstream. The actual ejection range issome distance from the
target as determined by the fire con-trol computer along with the
aircraft QE based on aircraftelevation, ground speed, and range to
target.

TYPE CLASSIFICATION:
STD (LCC) AMCTCM 3990, 3233, and 5178 Oct 65.
USE:
This is a general purpose high-explosive rocket that can
bepresently assembled in five different combinations of motorsand
fuzes.
DESCRIPTION:
This low-spin folding-fin aircraft rocket (LSFFAR) is an
air-to-ground rocket primarily deployed from rotary-wing andother
low-speed aircraft. It is also used on Air Force andNavy jet
aircraft in ripple fire and in a restricted single firemode.
The warhead consists of two main parts, a nose and a base,brazed
together. The nose section is threaded to receive afuze. The base
is made of steel and is threaded for attach-ment to rocket
motor.
Fuzes assembled with 2.75-inch rockets are classified aspoint
detonating (PD), or proximity, according to the mannerin which they
are initiated. Except for the Proximity FuzeM429, these fuzes are
nondelay and super-quick. The pointdetonating fuzes and proximity
fuzes are threaded into theforward end of the high explosive
warhead.
The M151 warhead is available with fuzes M423, M427,M429, and
M433. These fuzes differ from each other func-tionally and have the
following characteristics:
M423 and M427 - Oblique impact sensitive, point-detonat-ing,
super-quick type fuze.
M429 - Transistorized doppler type proximity fuze with
asuper-quick impact switch as a backup.
M433 - A resistance-capacitance multi-option time delayfuze with
selectable functioning modes for jungle canopypenetration, bunker
penetration and super-quick for open ter-rain.
The rocket motors are described in Chapter 5.
FUNCTIONING:
Fuze Functioning:
A typical PD fuze (M423 and M427) arms under minimum,sustained
acceleration. On impact with the target, the noseof the fuze is
crushed and the firing pin strikes the primer.Primer detonation
sets off, in sequence: the detonator, thebooster lead-in, the
booster, and the explosive in the war-head.
The M429 proximity fuze is a completely
transistorized,continuous wave, doppler device to provide airburst
charac-teristics. It was designed primarily for use with
high-explo-sive (HE) warheads for improved antipersonnel
lethalities.
The M429 proximity fuze is equipped with a super-quickimpact
switch which serves as a backup in the event of fail-ure of the
airburst electronics. The arming mechanism issimilar to that
contained in the M427 fuze except that it hasbeen modified to
include an electric detonator as well as a

battery starter assembly to initiate an electric battery.
Anelectric detonator is assembled in the rotor. A plastic
(lexan)sleeve houses the thermal battery which is located
directlyabove the safing and arming (S&A) mechanism.
The M433 fuze is an electronic multi-option delay timedelay fuze
with selectable functioning modes for forest can-opy penetration,
bunker structure penetration, and super-quick (SQ) for open
terrain. The fuze body is steel. A forestcanopy switch extends from
the nose of the fuze to signal tothe fuze electronic circuit when
first contact is made with thetree tops. An umbilical assembly is
positioned at the nose ofthe fuze for electrical connection to the
M132 fuze safetyand timing device located in the helicopter.
Internally, thefuze consists of a Resistance Capacitance (RC)
electronictime circuit, a safing and arming mechanism with an
electri-cal M84 detonator and a booster assembly.
The M433 fuze has a selectable time delay range thatdepends on
the height of the forest canopy (40 to 130 ft).After first contact
with the tree tops, a delay timer is acti-vated which results in
warhead functioning beneath the can-opy but above ground level. The
bunker structurepenetration mode is incorporated into the fuze to
defeat themedium hardness targets constructed of logs, earth,
bricks,etc. The fuze can be set from the cockpit for penetrating
upto 10 feet of protection and destroying the target fromwithin.
The hard target penetration RC timer is activated byinertial switch
sensing, setback in excess of 1000 G's. Also,an SQ point detonating
feature is included to provide opera-tional flexibility in open
terrain. This mode is achieved by
setting delay to zero. First contact with any surface deto-nates
the round.
The M433 has no internal battery. Required voltage is sup-plied
by the aircraft via the M132 safety and timing device160
milliseconds prior to the rocket being fired. During this160
millisecond period, fuze is charged to give time delayselected by
pilots.
The M433 fuze is to be used with M151 warheads.
Testing the M433 fuze against 3 ft thick wood barriers
indi-cates warhead detonations may occur 6 in. prior to exit
fromthe barrier to as much as 4.5 ft into the bunker void.
The M433 fuze nose cap is designed to provide fuze sensitiv-ity
on oblique/graze impacts. With the cap removed and thefuze set in
the delay mode, oblique/graze impact sensitivityis obtained through
the inertial action of the firing pin.
Because of the void sensing characteristics of the M433fuze,
complete destruction may be anticipated when a targethit is
achieved. It is recommended that rockets be fired inpairs at
minimum ranges and steep dive angles to enhancetarget hits.

Rocket Functioning:
When the rocket is launched with a PD fuze, it becomes arm-ed
from inertial forces resulting from sustained acceleration.This
frees the unbalanced rotor to turn and lock the explosivetrain in
the armed position. Upon impact with a target, thedetonator
functions and initiates the explosive train.
Upon detonation, the warhead shatters into thousands ofsmall,
high-velocity fragments.

DESCRIPTION:
This rocket is an air-to-ground rocket primarily deployedfrom
rotary-wing and other low-speed aircraft. It is alsoused on Air
Force and Navy jet aircraft in ripple fire mode.
This rocket is used to enhance the lethality and
destructive-ness of the 2.75-inch rocket in its aerial artillery
role. It usesthe M229 warhead which is an elongated version of
theM151 warhead and is commonly referred to as the
17-poundwarhead.
It consists of three main parts consisting of the nose, body,and
base. The three main parts are welded together. There is
an alternate two-piece design consisting of a one-piece nosebody
plus a base.
Fuzes assembled with 2.75-inch rockets are classified aspoint
detonating (PD) or proximity, according to the mannerin which they
are initiated. Except for the Proximity FuzeM429, these fuzes are

DIFFERENCES BETWEEN MODELS:
The nose and base of the M229 warhead are essentially iden-tical
to the M151 parts which are separated by the 10-inchlong
cylindrical body.
The table below identifies the differences between the
high-explosive M229 warhead incorporated within the
approvedconfigurations of motor and fuze.
FUNCTIONING:
Ignition: Functioning of the 2.75-inch rocket with an
M229warhead begins when the firing circuit switch is closed.Current
passes through the launcher firing contact to theigniter in the
rocket motor. This current generates the heatnecessary to initiate
the igniter charge, which ignites the pro-pellant grain. Combustion
gases from the burning propellantpressurize the chamber and exhaust
through the nozzle, pro-viding the unequal forces required for
rocket thrust.

Fuze Functioning: The M429 proximity fuze is a
completelytransistorized, continuous wave with doppler device to
pro-vide airburst characteristics. It is designed primarily for
usewith HE warheads for improved antipersonnel lethalities.
A super-quick impact switch on the M429 serves as a backupin the
event of failure of the airburst electronics. The armingmechanism
is similar to that contained in the M427 fuzeexcept that it has
been modified to include an electric deto-nator as well as a
battery starter assembly to initiate an elec-tric battery. An
electric detonator is assembled in the rotor.A plastic (lexan)
