Slide1:  DPC-814302-1.ppt.mh 03/04/2008 High Mobility Artillery Rocket System (HIMARS) Marine Exp Rocket System (MERS):  Highly Mobile Artillery Rocket System Offering MLRS Firepower on a Wheeled Chassis, Carries a Single Six-Pack of Rockets or One ATACMS on the U.S. Army’s New FMTV 5-Ton Truck. Fire Control System, Electronics, and Communications Units Are Interchangeable With the MLRS M270A1 Launcher Features: Same As MLRS Except for Launcher Platform Launched From Light Weight, Wheeled Launcher Transportable (See Attached Overview) High Mobility Artillery Rocket System (HIMARS) Marine Exp Rocket System (MERS) System Overview:  Max Feasible Commonality w/MLRS Transportable By C-130 Single MLRS Launch Pod Fire Mission/Reload Times Equal To Or Better Than MLRS Launcher On-board Fire Control & Navigational Control System Effectively Fires Entire MLRS On-board Reload System Family Of Munitions (MFOM) System Overview The High Mobility Artillery Rocket System:  The High Mobility Artillery Rocket System The HIMARS weapon system provides a unique capability to deliver devastatingly lethal and responsive fires while enhancing survivability, deployability, and sustainability compared to traditional general support weapon systems. The HIMARS weapons system has been selected by the U.S. Army for accelerated material acquisition to provide supporting fires to forces involved in rapid response and small-scale contingency operations. New rocket and missile munitions within the Multiple Launch Rocket System (MLRS) Family of Munitions (MFOM) are also being developed and fielded to provide the ground commander the required accurate, responsive, and effective fires throughout his area of interest. Both HIMARS and the new munition developments outlined in this document can significantly contribute to the delivery of responsive and effective fire support to the ground commander or to the Joint Task Force commander as part of a broader coalition strategy. The characteristics of the HIMARS weapon system are summarized in the chart below. HIMARS will be comparable to the M270A1 MLRS launcher in all areas of performance, capable of delivering the entire suite of current and future rocket and missile munitions and, most importantly, transportable by C-130 aircraft. HIMARS Vital Statistics:  HIMARS Vital Statistics Length: 6.94 meters Height (Operating): 3.18 meters 2.68 meters Wheelbase: 2.98 meters Engine: 290 hp 6.6 L. Diesel Speed 89 km/hr @ Gr. Wt. Width: 2.44 Meters Weight : Empty 13,592 kg w/Rockets 15,873 kg Fording Depth: .76 meters Trench: .76 meters Transmission: 6 x 6 Range: 480+ km Range of Munitions: 18 km-300 km Area and Point Targets Platform Assembly Torque Box Elevation Actuator Turret FMTV 5-Ton Truck Slide8:  The Fire Control Panel is the IFCS man/machine interface; it has a video display, full text keyboard, audio and visual alarms, and discrete switches. A new mass storage device will provide non-volatile storage of more than 1.0 gigabytes of data for use by IFCS software program modules. The Launcher Interface Unit (LIU) provides power and communications management for the IFCS. It contains the distribution center for the new high-speed data bus. The Power Switching Unit is the IFCS interface to the vehicle electrical power sources; it performs high current switching and power distribution functions in response to commands from the LIU. The Weapons Interface Unit is the IFCS interface with the Launch Pod Assemblies of the MLRS Family of Munitions. It contains a powerful computer processor that performs rapid ballistics calculations. Data processing and transfer rate to the weapons has been greatly increased to minimize time at the firing point. Growth has been built into the unit to accommodate future weapons. The Position Navigation Unit (PNU) provides navigation data via a self-contained inertial platform system, an embedded Global Positioning System (GPS) receiver module and an associated GPS antenna. The PNU provides the Launcher Module (LM) attitude and heading reference measurements and determines vehicle position. The PNU outputs earth-referenced vehicle position in three-dimensional UTM grid coordinates as well as coordinates of latitude and longitude. The PNU provides launcher azimuth heading from north and elevation angle from the horizontal plane. It furnishes position, attitude, and angular rate data required to aim the LM to a given azimuth and elevation; to stabilize the LM in elevation and azimuth prior to, during, and following single or ripple round firing operations, and to re-target the LM to different aiming parameters. The PNU uses GPS position solutions to enhance its inertial performance and to enable effective operational use of the launcher in the absence of land survey points.

The turret assembly accommodates the HIMARS elevation actuator servovalve package. It has provisions for the internal routing of electrical cabling and hydraulic lines. It interfaces directly with the azimuth/gear bearing and the HIMARS platform structure. The platform assembly attaches directly to the turret and provides the base that elevates the rocket/missile launch pod container for firing. It is capable of simultaneous elevation and azimuth slew from zero to 60 degrees in elevation and/or zero to 120 degrees in azimuth in 10 seconds.

Increased Flexibility in Positioning Increased Survivability HIMARS Improved Tactical Responsiveness:  HIMARS Improved Tactical Responsiveness Time at the launch point and resupply point are significantly reduced by the incorporation of the M270A1 ILMS and IFCS technologies. These two modifications enable the M270A1 to perform the aim and fire function in 17 percent of the time and the resupply function in 60 percent of the time required for the M270. Similar systems and timeline capabilities are designed into the HIMARS. Like the M270A1, no more time is required to aim for an over-the-side firing than for an over-the-cab firing. The result is less exposure to hostile fire and increased launcher survivability. The reload times shown assume the launcher is in the reload mode and a crewmember has the boom controller in hand.

This chart compares the ranges of the basic M26 rocket, the M26A1/A2 Extended Range Rocket, and the Guided MLRS (GMLRS) against the most common 155 mm cannon projectiles The M26 rocket provides a 33% increase in range over 155 mm DPICM, but has a range similar to the M864 Base Bleed round - only a 6% increase. The M26A1 can reach 43% farther than the M26. This equates to a 91% improvement in range over the basic 155 mm projectile, and 53% increase over the M864. The chart below provides insight into the advantage in area coverage provided by the M26A1/A2 rocket The M26 provides almost a 14% increase in area coverage when compared to the longer-range 155 mm Base Bleed projectile. The M26A1/A2 however, yields a 107% improvement in coverage over the basic M26 and 135% advantage over the 155 mm Base Bleed Significant Increase in Area Coverage with M26A1/A2:  Significant Increase in Area Coverage with M26A1/A2 Slide46:  Increased Accuracy Contributes to Increased System Effectiveness The M26A1 achieves a significant increase in delivery accuracy through a combination of both hardware and software improvements including an enhanced ballistic trajectory, and an improved dispersion pattern At 15 kilometers two volleys from HIMARS (12 M26 rockets) have the same lethality as 11 volleys (66 M483 projectiles) of DPICM delivered from a battery of 155mm cannons One Guided MLRS achieves the same level of expected damage as one battery (6 projectile) volley of XM982 DPICM cannon munitions HIMARS delivered munitions' lethality differential increases by a factor of ten when compared to cannons firing only HE projectiles. M26A1 and Guided MLRS - Increasing Accuracy While the M26A1/A2 has a range over 43% longer than the M26, it is actually more accurate at its maximum range of 45 kilometers than the M26 is at its maximum range of 32 kilometers. The difference in delivery accuracy between the M26 and M26A1/A2 is shown in the table below. The actual Circular Error Probable (CEP) figures are classified and are not shown.

When this is coupled with the ability to displace rapidly and move quickly across country, HIMARS is able to avoid counter-battery fire that will engage slower cannon units still in position, or trying to displace.

Projected loaded tactical weights (RSV 35K lb, RST 19.5K lb) Ammo truck has on-board materiel handling equipment (MHE). MHE is HIAB (COTS) derivative Prototype ammo truck and trailer at Fort Bragg for evaluation by 3/27 FAR Two ammo trucks/trailers to be fielded per launcher Tech/Op evaluation of ammo trucks / trailers to be conducted during PQT and IOT&E Ground Phase “Development of a C-130 Transportable Ammo Truck and Trailer is Ongoing” HIMARS C-130 Transportable Ammo Truck/Trailer Logistical Efficiency:  Logistical Efficiency Manpower Efficiency:  Manpower Efficiency A three-man crew operates a single HIMARS launcher; and while the crew on the HIMARS is less than half the size of a typical cannon crew, we have already seen the HIMARS is more effective, more survivable, and more operationally mobile. HIMARS was designed to maximize compatibility with the M270/M270A1. Existing programs used to train MLRS crewmen will require only minor modifications to educate the new HIMARS operators. Over time, soldiers can easily be cross-trained on both systems and be assigned to either type of unit Personal Savings Example:  Personal Savings Example Life-Cycle Manpower Savings:  Life-Cycle Manpower Savings Because of its greater effectiveness, HIMARS does not have to be substituted for cannon units on a “one for one” basis. A four-platoon battery will substitute for a four-battery 155m battalion. The HIMARS battery would have to be configured to customer nation needs, but about 134 soldiers would man an equivalent U.S. unit. A U.S. 155mm cannon battalion with four firing batteries would be about 500 men. A two-battery DS battalion might be as small as 300. In either case the personnel savings associated with the HIMARS battery are significant, as shown below. The annual “cost” of a soldier will, of course, vary significantly with rank, duty station, and time in service. Within the U.S. Army a planning factor of $45,000 per year is a reasonable estimate for budget computations. Using this figure (and the assumptions on unit size above) the annual personnel saving associated with replacing a cannon battalion with the HIMARS battery is $7.47 - $16.47 million. Given a system life span of 20 years, a life-cycle savings of $149 - $329 million could be realized – more than enough to pay for the HIMARS launchers.

(Your Gunnery Solution Can Be Exactly Right and Precisely Wrong) A Consistent 50 M TLE Without Sensor Fusion Is a Probable Best Case Scenario in the Counterfire Fight; A More Realistic Combat Situation (Fog of War, Multiple Firings, Stress, Lack of Absolute Locations on a True Common Grid) TLE Would Be in the 100 M Region The Mil Relation::  The Mil Relation: Where: W = Lateral Deviation From GT Line R = Range in Thousands M = Number of Mils To Get Deviation, Multiply Range by Mils Therefore: A 3 Mil System Yields a 120 Meter Deviation at 40 Km (40 x 3 = 120) A System Which Produces a Deviation of 50 Meters at 25 Km Range Is Operating at an Accuracy of 2 Mils
