Mk20
Rockeye
| The MK-20 Rockeye is a
free-fall, unguided cluster weapon designed to kill tanks and
armored vehicles. The system consists of a clamshell dispenser, a
mechanical MK-339 timed fuze, and 247 dual-purpose armor-piercing
shaped-charge bomblets. The bomblet weighs 1.32 pounds and has a
0.4-pound shaped-charge warhead of high explosives, which produces
up to 250,000 psi at the point of impact, allowing penetration of
approximately 7.5 inches of armor. Rockeye is most efficiently used
against area targets requiring penetration to kill. Fielded in 1968,
the Rockeye dispenser is also used in the Gator air-delivered mine
system. During Desert Storm US Marines used the weapon extensively,
dropping 15,828 of the 27,987 total Rockeyes against armor,
artillery, and antipersonnel targets. The remainder were dropped by
Air Force (5,345) and Navy (6,814) aircraft. |

high-explosive Drag factor: 40
The Snakeye version of the Mk82 has drag
fins which open upon release to rapidly decelerate the bomb. This
causes the bombs to hit well behind the plane, allowing a safe
egress from a low drop. This bomb is otherwise the same as the
Mk82. |

high-explosive Range: 5 miles Drag factor: 46
The GBU-15 uses a TV or imaging infrared
seeker to lock onto its target, then glides to the point of impact
using control fins. The GBU should be used for important and hard to
destroy targets like command bunkers, hardened aircraft shelters and
nuclear weapons plants. In addition, it can be used against targets
in civilian areas, The warhead of the GBU-15 is the same as the
Mk84. |

GBU-29, GBU-30,
GBU-31, GBU-32 Joint Direct Attack Munition (JDAM)
|
The Joint Direct Attack Munition
(JDAM) GBU-31 is a tailkit under development to meet both USAF and
Navy needs, with the Air Force as the lead service. The program will
produce a weapon with high accuracy, all-weather, autonomous,
conventional bombing capability. JDAM will upgrade the existing
inventory of general purpose and penetrator unitary bombs, and a
product improvement may add a terminal seeker to improve accuracy.
JDAM can be launched from approximately 15 miles from the target and
each is independently targeted.
JDAM is not intended to replace any
existing weapon system; rather, it is to provide accurate delivery
of general purpose bombs in adverse weather conditions. The JDAM
will upgrade the existing inventory of Mk-83 1,000- and Mk-84
2,000-pound general purpose unitary bombs and the 2,000-pound hard
target penetrator bomb by integrating a guidance kit consisting of
an inertial navigation system/global positioning system guidance
kit. The 1,000-pound variant of JDAM is designated the GBU-31, and
the 2,000-pound version of the JDAM is designated the GBU-32. JDAM
variants for the Mk-80 250-pound and Mk-81 500-pound bombs are
designated GBU-29 and GBU-30, respectively. Hard Target penetrators
being changed into low-cost JDAMs included the 2,000 pound BLU-109
and 1,000 pound BLU-110.
The JDAM will be continuously updated by
aircraft avionics systems prior to release. Once released, the
bomb's INS/GPS will take over and guide the bomb to its target
regardless of weather. Guidance is accomplished via the tight
coupling of an accurate GPS with a 3-axis INS. The Guidance Control
Unit provides accurate guidance in both GPS-aided INS modes of
operation and INS-only modes of operation. This inherent JDAM
capability will counter the threat from near-term technological
advances in GPS jamming. The weapon system allows launch from very
low to very high altitude and can be launched in a dive, toss, loft
or in straight and level flight with an on-axis or off-axis
delivery. JDAM also allows multiple target engagements on a single
pass delivery. JDAM provides the user with a variety of targeting
schemes, such as preplanned and inflight captive carriage
retargeting. JDAM is being developed by Lockheed Martin and Boeing [McDonald Douglas]. In
October 1995, the Air Force awarded a contract for EMD and for the
first 4,635 JDAM kits at an average unit cost of $18,000, less than
half the original $40,000 estimate. As a result of JDAM's pilot
program status, low-rate initial production was accelerated nine
months, to the latter half of FY 1997. On April 30, 1997, the Air
Force announced the decision to initiate low-rate initial production
(LRIP) of JDAM, with the first production lot of 937 JDAM kits. The
JDAM Integrated Product Team achieved a phenomenal 53 guided JDAM
weapon releases in the six months prior to the LRIP decision. JDAM
demonstrated high reliability and outstanding accuracy. Twenty-two
of the weapon releases were accomplished during an early Air Force
operational assessment. Over a four-week period operational crews
put JDAM through an operationally representative evaluation,
including targets shrouded by clouds and obscured by snow. All 22
weapons successfully performed up to their operational requirements
including overall accuracy of 10.3 meters, significantly better than
the 13 meter requirement. Early operational capability JDAMs have
been delivered to Whiteman Air Force Base, Mo., and low-rate,
initial production JDAM deliveries begin on 02 May 1998. McDonnell
Douglas Corporation of Berkeley, MO, was awarded on 02 April 1999, a
$50,521,788 face value increase to a firm-fixed-price contract to
provide for low rate initial production of 2,527 Joint Direct Attack
Munition (JDAM) kits. The work is expected to be completed by
January 2001. |

The CBU-87 is a
1,000-pound, Combined Effects Munition (CEM) for attacking soft
target areas with detonating bomblets. The CBU-87 CEM, an
all-purpose, air-delivered cluster weapons system, consists of a
SW-65 Tactical Munitions Dispenser (TMD) with an optional FZU-39
proximity sensor. The BLU-97/B Combined Effects Bomb (CEB),
effective against armor, personnel and material, contains a shaped
charge, scored steel casing and zirconium ring for anti-armor,
fragmentation and incendiary capability. The bomblet case is made of
scored steel designed to break into approximately 300 preformed
ingrain fragments for defeating light armor and personnel. A total
of 202 of these bomblets are loaded in each dispenser enabling a
single payload attack against a variety and wide area coverage. The
footprint for the CBU-87 is approximatel 200 meters by 400 meters.
The body of the submunition is cylindrical in shape, approximately
20 centimeters long, and has a 6 centimeter diameter. It is bright
yellow when new.
During Desert Storm the US Air Force
dropped 10,035 CBU-87s. During Allied Force the US dropped about
1,100 cluster bombs, and most of these were CBU-87s. The dud rate
for a standard cluster was approximately five
percent. |

The CBU-89 Gator Mine, a
1,000-pound cluster munition containing antitank and antipersonnel
mines, consists of a SUU-64 Tactical Munitions Dispenser with 72
antitank mines, 22 antipersonnel mines, and an optional FZU-39
proximity sensor. Mine arming begins when the dispenser opens. Mine
detonation is initiated by target detection, mine disturbance, low
battery voltage, and a self-destruct time-out. The antitank mine is
a magnetic sensing submunition effective against tanks and armored
vehicles. The antipersonnel mine has a fragmenting case warhead
triggered by trip wires. The US Air Force employed 1,105 CBU-89s
during the Gulf War. The Gator mine system provides a means to
emplace minefields on the ground rapidly using high-speed tactical
aircraft. The minefields are used for area denial, diversion of
moving ground forces, or to immobilize targets to supplement other
direct attack weapons. |
|
Gator consists of two companion systems.
The Air Force CBU-89/B is a 1000-pound class cluster weapon using
the SUU-64/B Tactical Munitions Dispenser (TMD). The TMD is the same
general configuration used for the CBU-87/B Combined Effects
Munition. This commonality allows for high-rate, low-cost production
of the dispenser. The Navy CBU-78/B is a 500-pound class cluster
weapon that uses the Mk7 Rockeye dispenser. Rockeye has been in
high-rate production for many years; the Mk7 dispenser is also a
low-cost item.
Both systems contain a mix of BLU-91 /B
antitank (AT) and BLU-92/B antipersonnel (AP) mines -- 72 AT and 22
AP for the CBU-89/B; 45 AT and 15 AP for the CBU-78/B. Commonality
of mines for both systems also contributes to high-rate, low-cost
production. The BLU-91 /B AT mine is the heart of the Gator system.
Microelectronics in each mine detect targets, discriminate armored
vehicles, and detonate the mine when the target reaches the most
vulnerable approach point. A Misznay-Schardin explosive charge
defeats the belly armor of most vehicles. The BLU-92/B AP mine
serves to discourage minefield clearing. Upon activation, the AP
mine explosion sends high-velocity fragments in a horizontal plane
over a wide area. Both mines have a programmable self-destruct
feature which permits the battlefield commander to control the
timing of a counterattack or defensive maneuver. The self-destruct
time is set just prior to aircraft takeoff using a simple selector
switch on the dispenser. This feature permits a high degree of
tactical flexibility during combat operations.
The size of the Gator minefield is
determined by the opening height of the dispenser. After dispenser
opening, the mines are self-dispersed using aerodynamic forces. The
mine pattern on the ground is directly proportional to opening
altitude, which is controlled by either the dispenser
electromechanical faze or an optional proximity sensor.
Aerojet Ordnance Company (AOC) is the
system integration prime contractor for Gator. All elements of the
system are either procured by Aerojet or furnished by the US
Government. The company is responsible for total system performance,
including live testing. Each month three Gator systems are randomly
selected from the production line and flight tested. Aerojet
Ordnance Company warrants system performance for five years,
assuring Gator reliability. |
BLU-107/B
Durandal
Type: Anti-runway cratering
bomb Length: 8 ft 2 in Weight: 450 lb Warhead: 330 lb
high-explosive Drag factor: 40 |
 |
The Durandal was designed
solely for the purpose of destroying runways. The bomb first
penetrates the runway surface and then a delayed explosion buckles a
large portion of the runway - damage much more difficult to repair
than the crater of a general-purpose bomb. Note that a bomb hit
toward the end of a runway might not destroy enough pavement to put
the runway completly out of
action. |
Mk-106
This 5-pound practice bomb is a thin-cased
cylindrical bomb used to simulate retarded weapon delivery. The bomb
is composed of the bomb body, a retractable suspension lug, a firing
device, and box-type conical fins.The firing device consists of a
safety pin, a firing pin head, a cotter pin, a spring, and a disc.
The firing pin head is the main body of the device and is threaded
so it can be screwed into the forward end of the bomb body. The
spring and the disc prevent the practice bomb signal cartridge from
striking the firing pin, located on the face of the firing pin head,
until it meets sufficient resistance to force the cartridge into the
firing pin. This resistance is normally met when the weapon
impacts the target, but for added safety during ground handling, the
safety pin is installed into the firing pin head and secured by a
cotter pin. The safety pin and cotter pin are removed before flight. |

| The BLU series bomb bodies
use PBNX-109 as explosive filler. The BLU-109A/B used with the
GBU-24 and GBU-31(V)4/B is a special purpose bomb comprised of steel
alloy used for hardened targets. The BLU-109/B (I-2000) is an
improved 2,000-pound-class bomb designed as a penetrator without a
forward fuze well. Its configuration is relatively slim, and its
skin is much harder than that of the standard MK-84 bomb. The skin
is a single-piece, forged warhead casing of one-inch, high-grade
steel. Its usual tail fuze is a mechanical-electrical FMU- 143. The
1,925-pound bomb has a 550-pound tritonal high-explosive blast
warhead. The BLU-109/B was always mated with a laser guidance kit to
form a laser-guided bomb in Desert
Storm. |
BDU-33
| Practice ordnance
includes 25-pound BDU-33 bombs having a spotting charge that
releases a cloud of smoke on impact. The BDU-33 is used to simulate
the MK 82 in low drag configuration. The munitions to be loaded onto
aircraft are brought to the flightline on a trailer. The BDU-33
bombs are lifted out of a metal cage on a trailer and are locked in
place underneath the aircraft. The BDU-33 bombs are lifted out of a
cage on the trailer and carried to the aircraft 20 feet away. BDU-33
munitions are loaded onto TERs (Triple Ejector Racks) and SUUs
(Suspension Units). The BDU-33 is pushed against a spring loaded
catch and locked into place. The unloading of the BDU-33 from the
aircraft involves loosening the bolts and releasing the spring. The
BDU-33 is carried back to the trailer. |

Mk-36 DST Destructor
Mine
Destructor Mines
are general purpose low-drag bombs converted to mines. They can be
deployed by air, either at sea as bottom mines or on land as land
mines. With the MK 75 Modification Kit installed, a MK 82 bomb (500
pounds) becomes a MK 36 DST. The conflict in Southeast Asia saw
the introduction of a different kind of mine called a Destructor
(DST). Destructors Mk 36, Mk 40, and Mk 41 are aircraft-laid bottom
mines which use General Purpose (GP) Low-Drag Bombs Mk 82, Mk 83,
and Mk 84, respectively as the mine case and explosive charge. The
bombs are converted to mines with the installation of a kit of
modular components that comprise a mine-type arming, detector, and
firing system. The kit contains an arming device, an explosive
booster, a magnetic-influence firing mechanism and associated
hardware. The arming device and booster install in the bomb's nose
cavity and the firing-mechanism (with battery) installs in the
bombıs tail cavity. The same kit of components and method of
assembly are used for each one of the destructors, but the kits are
available in a number of configurations, each with a different
circuitry to meet a variety of operational requirements. It should
be noted, however, that since the bomb cases are small, medium, and
large, they require different flight gear. DSTıs became the first
mines to be used on both land and sea. When dropped on land, they
bury themselves in the ground on impact, ready to be actuated by
military equipment, motor vehicles and personnel. When dropped in
rivers, canals, channels, and harbors, they lie on the bottom ready
to be actuated by a variety of vessels including war ships,
freighters, coastal ships, and small craft. |
|
CBU-52/58/71
| The CBU-52, -58 and
-71 all use SUU-30 dispensers, a metal cylinder divided
longitudinally. One-half contains a strong back section that
provides for forced ejection and sway-bracing. The two halves lock
together. Four cast aluminum fins are attached at a 9~degree angle
to the aft end of the dispenser and are canted 1.25 degrees to
impart spin-stabilized flight. When released from the aircraft, the
arming wire/lanyard initiates the fuze arming and delay cycle. At
fuze function, the fuze booster ignites and unlocks the forward end
of the dispenser. Ram air action on the dispenser forces the two
halves apart, instantaneously dispensing the payload and allowing
the bomblets to spin-arm and self-dispense. A total of 17,831 were
expended during the Gulf War. |
