Full Description:
FIELD OF THE INVENTION 
     The present invention relates generally to missile launcher systems. More particularly, the present invention relates to a multi-purpose missile launcher system for a military land vehicle that is preferably a modular system that mates with a modular bed of the military land vehicle. 
     BACKGROUND OF THE INVENTION 
     The use of weapon systems in connection with military land vehicles is well known. The tank is perhaps the most familiar of such vehicles, although smaller weapon systems such as machine guns, as well as mortar and artillery also have been adapted for use with a variety of military land vehicles often referred to as light armored vehicles. 
     The most common way of integrating a smaller weapon system onto a military land vehicle is to use a rotatable turret arrangement such as described in U.S. Pat. No. 4,574,685. The type of turret arrangement is the most flexible for targeting shorter range land based targets. Various ways in which a single larger gun or rocket system can be integrated with a military land vehicle are described in U.S. Pat. Nos. 5,129,308 and 6,000,313. These types of arrangements are better suited for long range or air-based targets. U.S. Pat. No. 3,757,635 describes a mulit-purpose munition carrier that can incorporate a single larger gun or rocket system and also features two detachable personnel capsules mounted in a pod-like arrangement on extensible arms of the tracked vehicle. 
     Until recently, the use of rocket and missile systems as a land-based weapon has been primarily limited to larger single rocket arrangements. Designs for the use of multiple rocket launching systems on ships have been known. U.S. Pat. Nos. 4,063,485 and 4,305,325 describe multiple decoy launcher systems for use with a ship that are fixed and positionable, respectively. U.S. Pat. Nos. 3,106,132 and 3,865,009 describe dual rotatable multiple rocket launcher systems also for use with a ship. U.S. Pat. No. 5,452,640 describes a multiple rocket launcher system for use with a ship that includes both fixed and positionable rocket launchers. U.S. Pat. No. 5,129,307 describes a pair of side-mounted rocket launcher systems that track simultaneously with an integrated naval gun. U.S. Pat. No. 5,020,412 also describes a pair of side-mounted rotatable rocket launcher systems that are integrated with a rocket magazine conveyer system on a ship. 
     Generally, the designs of multiple rocket launcher systems for ships are not well suited for use in connection with military land vehicles because of the significant differences in size, configuration and operation. U.S. Pat. No. 5,269,214 describes a plurality of projectile tubes that are mounted as part of a magazine block arrangement in a fixed orientation on a plate on the side of a tank, for example, as a defensive mechanism. Once the projectiles in a given magazine block have been fired, the magazine block is released by an operator from the plate and a new magazine block can be manually inserted into the plate. While this type of arrangement is adequate for smaller, shorter-range projectiles, it is not adequate for medium and larger size rocket launcher systems. 
     In recent years, there have been significant changes in the way in which military operations are conducted. Increasingly, the emphasis is on making ground-based military equipment lighter and more mobile so that the equipment can be easily transported to a desired location. Another emphasis has focused on designing military equipment to be more modular and make use of common components so as to decrease costs while increasing both flexibility and maintainability of the equipment. One example of this trend is the GTK European modular military vehicle which consists of an eight wheel driving module and a separable and detachable mission module that rides in a modular bed at the rear of the vehicle. 
     U.S. Pat. No. 5,461,961 describes a combat land vehicle with a rocket launcher that is separable for purposes of loading both components into an aircraft. The rocket launcher assembly includes a collar that rotates the rocket launcher in a horizontal orientation and an intermediate structure that raises and lowers the open end of the rocket launcher to adjust the elevation at which the rockets can be fired. While this arrangement allows multiple rocket launchers for medium and larger size rockets to be incorporated as part of a land military vehicle, the arrangement does not allow for a weapon system that can effectively target both short and medium range land targets, as well as launching rockets against longer-range land targets or air targets. 
     It would be desirable to provide a multi-purpose missile launcher system for a military land vehicle that can be deployed as part of a modular weapon system that mates with a modular bed of the military land vehicle and that has the capability of effectively targeting both short and medium range land targets, as well launching missiles against longer-range land targets or air targets. 
     SUMMARY OF THE INVENTION 
     The present invention is a multi-purpose missile launcher system for a military land vehicle that has the capability for direct targeting both short and medium range land targets, as well as launching missiles against longer-range land targets or air targets using indirect targeting. Preferably, the multi-purpose missile launcher system is deployed as part of a modular weapon system that mates with a modular bed of the military land vehicle. 
     A base structure is configured to operably and detachably mate with the modular bed of the military land vehicle. A first multiple missile system is operably attached to the base structure and selectively positionable in both vertical and horizontal orientations and selectively movable to multiple heights relative to the base structure for direct targeting of the first multiple missile system against short and medium range land targets. A second multiple missile system is also operably attached to the base structure, but in a fixed and generally vertical orientation for indirect targeting against long range land targets or against air targets. In the preferred embodiment, the first missile system includes at least a pair of independently positionable multiple missile modules carried in a retracted position during transport and selectively movable to an extended position for firing. 
     For purposes of the present invention, direct targeting will refer to the ability to position a missile system in an orientation in which the missile will be fired at a land based target generally along a line-of-sight target acquisition. Indirect targeting, on the other hand, will refer to the launching of a missile system at an altitude of greater than 45 degrees against a land target or launching a missile system against an air target.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The present invention relates to a portable multi-purpose missile launcher, as most clearly illustrated at  10  in FIG.  1 . The portable multi-purpose missile launcher  10  has an integrated, self-contained configuration that permits the multi-purpose missile launcher  10  to be loaded onto a military land vehicle  12 , as illustrated in FIG. 2, to transport the multi-purpose missile launcher  10  to a location where the multi-purpose missile launcher  10  is to be used. 
     The multi-purpose missile launcher  10  preferably includes a base structure  20  and a weapon system platform. Operably attached to the weapon system platform is a first multiple missile system  22 , a second multiple missile system  24  and a third weapon system  26 . Each of the weapon systems is preferably designed to address a different type of potential target. 
     The base structure  20  has a generally rectangular shape and is formed with a length and width based upon the type of transport vehicle with which the multi-purpose missile launcher  10  is intended to be used. For most applications, the base structure  20  has a length that is preferably less than about 14 feet and a width that is preferably less than about 8 feet. Forming the base structure  20  with these dimensions permits the multi-purpose launcher  10  to be placed on conventional cargo trucks used by the military including a medium tactical vehicle used by the United States Army that is identified as M1083. The multi-purpose launcher  10  is also suitable for use with the M998 Series High-Mobility Multipurpose Wheeled Vehicles (“HMMWV,” or “humvee,” or “hummers”) used by the United States Army. 
     The base structure  20  preferably has a bottom surface  30 , a pair of side surfaces  32  and a pair of end surfaces  34  (only one of which is shown). The base structure  20  also preferably includes an angled surface  36  intermediate the bottom surface  30  and each of the side surfaces  32 . 
     The components of the base structure  20  are each preferably fabricated from a metallic material that is capable of protecting the components placed in the base structure  20  from damage while transporting the multi-purpose missile launcher  10  to the location where the mulit-purpose missile launcher  10  is to be used. The base structure  20  is preferably fabricated with a substantially water-impervious configuration to prevent water from contacting components inside of the base structure  20 . 
     The first multiple missile system  22  is preferably designed for striking ground-based targets that are located further from the multi-purpose missile launcher  10 . The first multiple missile system  22  is also preferably designed for striking more thoroughly protected targets such as targets that are protected with armor. 
     The first multiple missile system  22  preferably includes a pair of first missile modules  40  that are mounted to either side of the base structure  20 . The first multiple missile system  22  preferably includes the ability to aim the missile system in a horizontal manner, a vertical manner, or any plurality of orientations between horizontal and vertical. Providing the first multiple missile system  22  with a plurality of directional capabilities reduces the complexity and associated costs needed in guidance systems for the first multiple missile system  22 . 
     The first missile modules  40  are preferably mounted to move between a retracted position (as illustrated in FIG. 2) and an extended position (as illustrated in FIG.  3 ). Positioning the first missile modules  40  in the retracted position reduces the overall dimensions of the multi-purpose missile launcher  10  to facilitate transportation of the multi-purpose missile launcher  10  to a desired use location. For example, positioning the first missile modules  40  in the retracted position enables the multi-purpose missile launcher  10  and its transport vehicle to be placed on a conventional military transport plane such as a C130. Prior to use, the first missile modules  40  are pivoted from the retracted position to the extended position. 
     Each of the first multiple missile systems  22  also include a platform  42  that is pivotally mounted to an elevated central section  44 . When in the retracted position, the platform  42  is preferably in a substantially vertical orientation. When in the extended position, the platform  42  is preferably in a substantially horizontal orientation. Pivoting of the platform  42  between the vertical orientation and the horizontal orientation is preferably controlled with a hydraulic cylinder or similar mechanism  46 . 
     The missile module  40  is rotatably and pivotally mounted to the platform using a mounting mechanism  50 . The mounting mechanism  50  includes a base  52 , support arms  54  and a hydraulic cylinder  56 . The base  52  is rotatably mounted to the platform  42 . Rotation of the base  52  with respect to the platform  42  is preferably controlled by a motor (not shown) using techniques that are known to those having ordinary skill in the art. 
     The support arms  54  extend from the base  52  to the missile module  40  and thereby pivotally attach the missile module  40  to the base  52 . The hydraulic cylinder  52  is operably attached between the missile module  40  and the base  52  and control pivoting of the missile module  40  with respect to the base  52 . 
     The first multiple missile system  22  is also preferably mounted for movement between the retracted position (as illustrated in FIG. 2) and a reloading position (as illustrated in FIG.  4 ). Movement of the first multiple missile system  22  to the reloading position is particularly suited for when the multi-purpose missile launcher  10  is on the transport vehicle  12  because when the first multiple missile system  22  is in the reloading position, the first missile modules  40  are sufficiently close to the ground surface to permit a person to manually reload the first missile modules  40  while standing on the ground. 
     The first missile module  40  is rotated with respect to the platform  42  so that the missile module  40  is in a generally vertical orientation with a front end  60  of the missile module  40  oriented above a back end  62  of the missile module  40 . In this orientation the back end  62  is sufficiently close to the ground to permit missiles to be loaded into the missile module  40  through the back end  62 . 
     The first missile module  40  is preferably configured to include an array of missiles  64 . The number of missiles  64  included in each of the first missile modules  40  is selected based on the size of the individual missiles  64  and the size of the first missile modules  40 . Preferably, each of the first missile modules  40  includes 6 missiles that are configured in an array having 3 columns and 2 rows. An example of a missile that is suitable for use with the present invention is available under the designation “Hellfire.” 
     The second multiple missile system  24  is preferably designed for striking air-based targets or ground-based targets located a relatively far distance away from the multi-purpose missile launcher  10 . The second multiple missile system  24  includes at least one missile  70  that is mounted in a substantially vertical orientation. The second multiple missile system  24  preferably has an array of missiles  70  that are aligned along rows and columns. In a preferred embodiment, there are 5 rows and 5 columns of missiles. However, a person of ordinary skill in the art will appreciate that the number of missiles  70  is selected based upon the size of the individual missiles  70  as well as the overall size of the second multiple missile system  24 . 
     The second multiple missile system  24  is preferably configured in a modular manner that permits the entire second multiple missile system  24  to be separated from the multi-purpose missile launcher  10  when all of the missiles have been fired. Additionally and/or alternatively, the second multiple missile system  24  is configured to permit individual missile modules  72  to be removed therefrom. Removing individual missile modules  72  from the second multiple missile system  24  allows missiles that have specialized characteristics to be placed into the second multiple missile system  24 . 
     Because the missiles used in conjunction with the second multiple missile system  24  are launched in a substantially vertical manner, the missiles  70  used in the second multiple missile system  24  must have more control circuitry than the missiles used in conjunction with the first multiple missile system  22  where the missiles are generally aimed towards the intended target before firing. 
     The third weapon system  26  is preferably designed for striking ground-based targets that are located a relatively short distance from the multi-purpose launcher  10 . The third weapon system  26  preferably includes a conventional artillery gun. Alternatively, the third weapon system  26  may include more advanced guns that include guidance capabilities. 
     The third weapon system  26  is preferably mounted on a telescoping platform  76  that permits the third weapon system  26  to be moved vertically with respect to the multi-purpose missile launcher  10 . Moving the third weapon system  26  vertically enables the third weapon system  26  to be positioned above obstacles located proximate the multi-purpose missile launcher  10 . 
     The third weapon system  26  is preferably rotatably and pivotally mounted to the telescoping platform  76 . Rotatably and pivotally mounting the third weapon system  26  to the platform  76  enables the third weapon system  26  to be pointed toward a desired target. 
     Operation of the multi-purpose missile launcher  10  is preferably controlled by a control system that is substantially located within the multi-purpose launcher  10 . The control system includes all of the components needed to operate the first multiple missile system  22 , the second multiple missile system  24 , and the third weapon system  26 . 
     In particular, the control system controls the movement of the first multiple missile system  22  between the retracted position, the extended position, and the reloading position. The control system also controls the horizontal rotation and the vertical pivoting of the first missile module  40  as well as the firing of the first missile module  40 . 
     The control system also controls the firing of missiles  70  from the second multiple missile system  24 . Additionally, the control system controls the vertical movement, rotation and pivoting of the third weapon system  26 . 
     The multi-purpose launcher  10  preferably has a standardized size that permits the mulit-purpose launcher  10  to be used with transport vehicles  12  having a variety of characteristics that are selected based upon the area in which the multi-purpose launcher  10  is to be used. For example, the transport vehicle  12  may be motorized or non-motorized, wheeled or tracked. The transport vehicle  12  preferably has a motorized and wheeled configuration. Such a design enables the transport vehicle to travel on-road or off-road to the desired use location under its own power. 
     The transport vehicle  12  preferably includes a compartment  80  in which at least one person who is operating the transport vehicle  12  may sit. Preferably, the compartment  80  has space for 2 persons—one who has primary responsibility for driving the transport vehicle and one who has primary responsibility for controlling the operation of the multi-purpose launcher  10 . Alternatively, operation of the transport vehicle  12  and the multi-purpose missile launcher  10  may be controlled remotely by operators who are located a distance away from the transport vehicle  12  and the multi-purpose missile launcher  10 . 
     The transport vehicle  12  preferably includes a substantially flat support surface  82  (not shown) with a size that is approximately the same as the size of the transportable base  20  on the multi-purpose launcher  10 . The transport vehicle  12  also preferably includes side supports  84  that extend around at least three sides of the multi-purpose launcher  10 . The side supports  84  not only assist in retaining the multi-purpose launcher  10  in a desired location on the transport vehicle but also provide protection to a portion of the components in the multi-purpose launcher  10 . 
     A back side of the transport vehicle  12  preferably has either a removable enclosure or no enclosure to permit either the entire multi-purpose launcher  10  or selected portions of the mulit-purpose launcher  10  to be readily removed from the transport vehicle  12  such as it is desired to change the components in the multi-purpose launcher  10  or it is necessary to reload the mulit-purpose launcher  10 . 
     To facilitate replacing components such as the vertically oriented missile modules  72  without the use of equipment in addition to the transport vehicle  12 , the transport vehicle  12  may include a lift mechanism  86 . The lift mechanism  86  lowers spent vertically oriented missile modules  72  to a ground surface and then lifts replacement vertically oriented missile modules  12  to the height necessary for the vertically oriented missile modules  72  to be connected to the multi-purpose launcher  10 . A person of ordinary skill in the art will appreciate that it is also possible to use the lift mechanism  86  to change the types of missiles in the multi-purpose launcher  10  for particular conditions under which the multi-purpose launcher  10  will be used such as using increased range missiles. 
     The lift mechanism  86  preferably includes at least two tines that extend therefrom in a configuration that is similar to a conventional forklift. When not in use the lift mechanism  86  preferably retracts into a position beneath the multi-purpose launcher  10 . 
     The transport vehicle  12  also preferably includes a lateral movement mechanism  90  (not shown) that permits the banks of vertically oriented missiles to be moved laterally from their position in the multi-purpose launcher  10  to a position on the lift mechanism  86 . A person of ordinary skill in the art will appreciate that a variety of configurations may be used for the lateral movement mechanism  90  such as a hydraulic cylinder. 
     In operation, the multi-purpose launcher  10  is placed on a transport vehicle  12  to transport the multi-purpose launcher  10  to a location where the multi-purpose launcher  10  is to be used. Once reaching the desired use location, the multi-purpose launcher  10  may be used from its position on the transport vehicle  12 . Alternatively, the multi-purpose launcher  10  may be unloaded from the transport vehicle  12  and left at the operation location. 
     The multi-purpose launcher  10  does not require the transport vehicle  12  to have any special characteristics to permit the use of the multi-purpose launcher  10  from on the transport vehicle or when unloaded from the transport vehicle as all of the control circuitry needed to operate the multi-purpose launcher  10  is included in the multi-purpose launcher  10 . 
     The control system of the multi-purpose launcher  10  permits the operation of the mulit-purpose launcher  10  to be controlled from a remote location using conventionally known communications technology such as transmitting the control instructions using radio signals. 
     It is contemplated that features disclosed in this application, as well as those described in the above applications incorporated by reference, can be mixed and matched to suit particular circumstances. Various other modifications and changes will be apparent to those of ordinary skill.
