Maj. Gen. Don Shepperd: New weapons for new war
October 14, 2001 Posted: 7:34 a.m. EDT (1134 GMT)
Update: It looks to me like we've taken
care of the air defense system, although
it's not totally destroyed. Now we're
starting to go against the fielded forces
and the underground targets. A lot of them
are deeply buried. The big difference is we
used to have laser-guided weapons, which
were very accurate but required good
weather. We now have a whole new
family of weapons that can hit in any kind
of weather and day or night. We've made
some awesome steps forward.
Impact: The whole idea is to weaken the
Taliban and to make them weaker relative
to the Northern Alliance and other forces.
It's not a question of if it's going to
happen; it's just a case of when. A lot of
those underground facilities were built
with our help; the CIA provided
intelligence and money, and we know a lot
about those bunkers. But a lot of them are deeply buried. These are very difficult.
Strategy: The strategy is to set the conditions to allow the Taliban to be replaced
and to go against the terrorists -- to weaken them so other factions can move in.
We're setting the stage for the capability to put in larger number of ground forces.
We'd love to do this with the Northern Alliance taking over, but we may not be able
to.
Tactics: We're after fielded forces with the new weapons. We've got a weather
window closing in on us, and that really does hamper us, especially if we're
thinking of putting ground troops in. The weaponry at some point becomes a minor
player when the diplomatic, legal and financial aspects become extremely important.
God and the soldier we adore, In time of danger, not before!
The danger passed, and all things righted, God is forgotten and the soldier slighted.

Joint Direct Attack Munition (JDAM)
GBU-29, GBU-30, GBU-31, GBU-32
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.
Mission plans are loaded to the host aircraft prior to take off and include release envelope, target coordinates and
weapon terminal parameters. The weapon automatically begins its initialization process during captive carry when
power is applied by the aircraft. The weapon performs bit, and aligns its INS with the host aircraft’s system.
Targeting data is automatically down loaded to the weapon from the host aircraft. When the host aircraft reaches the
release point within the Launch Acceptable Region (LAR), the weapon is released. Weapon maneuverability and
range are enhanced by fixed aerodynamic surfaces (mid-body strakes) attached to the bomb body.
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 Global Positioning System (GPS) with a 3-axis
Inertial Navigation System (INS). The Guidance Control Unit (GCU) provides accurate guidance in both
GPS-aided INS modes of operation (13 meter (m) Circular Error Probable (CEP)) and INS-only modes of operation (30 m CEP). INS only is defined as GPS
quality hand-off from the aircraft with GPS unavailable to the weapon (e.g. GPS jammed). In the event JDAM is unable to receive GPS signals after launch for any
reason, jamming or otherwise, the INS will provide rate and acceleration measurements which the weapon software will develop into a navigation solution. 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 kits. The work is
expected to be completed by January 2001.
On 28 April 2000 McDonnell Douglas Corp., Berkeley, Mo., was awarded a $5,648,796 modification to a firm-fixed-price contract to provide for incorporation of
Pin-Lock Tail Actuator System technology into the production effort for 8,163 Joint Direct Attack Munition kits. The Pin-Lock Tail Actuator System provides a
more durable and accurate method of maneuvering the tail fins of the JDAM than the existing Friction Brake technology. Expected contract completion date was 31
March 2001.
The JDAM program is nearing the end of its development phase. More than 250 flight tests involved five Air Force and Navy aircraft. JDAM will be carried on
virtually all Air Force fighters and bombers, including the B-1, B-2, B-52, F-15E, F-16, F-22, F-117, and F/A-18.
JDAM was certified as operational capable on the B-2 in July 1997. Limited Initial Operational Capability was achieved on the B-52 in December
1998.
The B-1B Lancer conventional mission upgrade program is configuring the B-1B to carry out its role as the primary Air Force long-range heavy bomber for
conventional warfare. The 11 Feb 1998 drop from a B-1B was the 122nd guided JDAM launch. The depot at Oklahoma City Air Logistics Center will install the
modification kits in the initial block of bombers by January 1999, giving Air Combat Command seven JDAM-capable B-1B bombers 18 months ahead
of the initial program schedule.
Potential Upgrades
The JDAM product improvement program may add a terminal seeker for precision guidance and other system improvements to existing JDAMs to provide the Air
Force with 3-meter precision and improved anti-jamming capability. The Air Force is evaluating several alternatives and estimates that the seeker could be available
for operations by 2004. The seeker kit could be used by both the 2,000-pound blast fragmentation and penetrator JDAMs.
The Advanced Unitary Penetrator (AUP), a candidate to be integrated with a GBU-31 guidance kit, is a 2000 lb. class penetrator warhead intended as an
upgrade/replacement for the BLU-109 warhead in applications requiring increased penetration. The AUP is designed to provide increased penetration capability
over the BLU-109 warhead while maintaining the same overall weight, mass properties, dimensions, and physical interfaces associated with the BLU-109 warhead.
This concept integrates the AUP warhead with the GBU-31, the JDAM tail kit for 2,000 lb class warheads. This concept uses the Hard Target Smart Fuze (HTSF),
an accelerometer based electronic fuze which allows control of the detonation point by layer counting, distance or time. The accelerometer senses G loads on the
bomb due to deceleration as it penetrates through to the target. The fuze can distinguish between earth, concrete, rock and air.
The boosted penetrator concept is based on achieving maximum penetration without sacrificing operational flexibility. Total system weight will be less than 2,250
pounds so that it can be carried by all AF tactical aircraft and bombers as well as the Navy’s F/A-18. The goal is to achieve greater penetration than the GBU-28
with a near term, affordable design. A dense metal warhead will be used with a wraparound rocket motor to allow internal carriage in the F-117. Advanced
explosives will be used to compensate for the reduced charge weight. This concept integrates the boosted penetrator warhead with a JDAM guidance kit with an
adverse weather Synthetic Aperture Radar (SAR).
The Ballasted Penetrator in GBU-32 concept is a 1000 pound dense or ballasted penetrator integrated with a GBU-32 guidance kit using compressed carriage for
internal carriage in advanced fighters (F-22, JSF) or carriage in cruise missiles (JASSM, CALCM, ACM, ATACMS, Tomahawk.) The warhead would either be
designed with a dense metal case or contain dense metal ballast for maximum penetration. The warhead will be filled with an advanced insensitive explosive to
compensate for the reduced charge weight. The warhead will be integrated with the GBU-32, the JDAM tail kit for 1,000 lb class warheads.
The Boosted Unitary Penetrator concept is based on achieving maximum penetration in a weapon that will fit internally in the F-22. Total system weight will be less
than 1300 pounds. A dense metal warhead will be used with a wraparound rocket motor. Use of next generation compressed seekers and aero-control designs
along with reaction jet control will allow the size to shrink sufficiently to fit inside F-22 and JSF. Advanced explosives will be used to compensate for the reduced
charge weight. This concept integrates the boosted penetrator warhead with a JDAM guidance kit with an adverse weather Synthetic Aperture Radar (SAR).
The JDAM/BLU-113 concept improves the GBU-28 by enhancing the nose design of the BLU-113 warhead for improved penetration. The warhead nose reshape
will improve BLU-113 penetration by more than 25%. The penetration could potentially be further improved by replacing the traditional HE fill with a dense
explosive. The design involves integrating the improved BLU-113 warhead with a JDAM tail kit.
The Compressed Carriage GBU-32, J1K, enhanced fill concept is a JAST-1000 warhead with enhanced fill integrated with a GBU-32 guidance kit using
compressed carriage for internal carriage in advanced fighters (F-22, JSF) or carriage in cruise missiles (JASSM, CALCM, ACM, ATACMS, Tomahawk.) The
warhead is a combined penetrator and blast/fray warhead. The warhead shape is optimized for penetration and the enhanced fill and internal liner provide blast and
controlled fragmentation capability. The warhead is shrouded to match the MK-83 mass properties and interfaces. The warhead will be integrated with the GBU-32,
the JDAM tail kit for 1,000 lb class warheads. Use of aero-control designs along with reaction jet control will allow the size to shrink sufficiently to fit inside F-22
and JSF. This concept uses the Hard Target Smart Fuze (HTSF).
The Direct Attack Munitions Affordable Seeker (DAMASK) Fleet Advanced Demonstration (FAD) accuracy
enhancement kit is a seeker of the lowest possible cost that will improve JDAM accuracy to three-meter circular
error probability (CEP). The three-year FAD began in FY 98 and continued through FY 00. DAMASK includes a
very low-cost sensor mounted to the front of a JDAM and an off-the-shelf signal processor mounted in the existing
JDAM tail kit. It uses an uncooled imaging-infrared focal plane array (UIIFPA) sensor and low-cost optics, both
developed for the consumer automobile market. An off-the-shelf, commercially available signal processor is the final
component of the accuracy upgrade kit, estimated to cost less than $12.7 thousand per seeker in quantity. During
the final stages of weapon flight, DAMASK's unique guidance system will image the target area, locate a
mission-planned aimpoint and update the JDAM target location. The mission-planning image can come from
satellite, uninhabited air vehicles or reconnaissance aircraft. A template is then automatically produced from the mission-planning image and loaded on board the
aircraft with the baseline JDAM mission plan. Organic targeting is possible because the target area can be imaged with onboard synthetic aperture radar (SAR) or
forward looking infrared (FLIR) sensors, and the pilot can then select the desired impact point using a heads-down display.
