     FIGS. 10-12 depict the electrical system architecture for the present invention. The electrical system architecture is compatible with the essence of the invention which enables adaptability to a variety of existing and future mission requirements. The electrical and control systems and its architecture are discussed in detail hereinbelow in conjunction with the operations of the multi-purpose launcher systems. 
     Referring now to FIGS. 1-2, a trainable/elevatable box launcher 10 is shown connected to rotatable platform 12. Particularly, pistons 14 are connected to launcher 10 and platform 12. Further, hinge 16 provides connection between launcher 10 and platform 12. Accordingly, when pistons 14 are extended, launcher 10 is elevated. Further, the system becomes trainable when platform 12 is rotated. Thus, the present invention provides a pointing capability by elevating launcher 10 and enables pointing in a selected direction by rotating platform 12. These features provide optimum area coverage and can accommodate ordinance which requires more precise target placement before deployment. Launch tube clusters 18 which comprise a variety of rounds enable the system to provide multipurpose functions. Some of these functions include the use of launcher 10 to house rockets, missiles, chaff and decoy for ship self-defense. 
     The train and elevation mechanism (not shown) include electric drives which are not presently utilized on navy pointing launchers. The electric drives to train or elevate are the same type motors with step functions to perform training and elevation as apparent. The control system and electronics package will be compatible with the system architecture shown in FIG. 10. Power is supplied from ship&#39;s power distribution system. A typical Multi-Purpose Chaff/Decoy and Rocket Launcher (MCDRL) system comprises an MCDRL control module 64, having a two-way connection with MCDRL launch control unit 66. MCDRL control module 64 is provided with a two-way connection to a circuit for a multiplex (SELECT MUX) 68 operation which includes a switching mechanism and selecting/monitoring mechanism for the type of ordnance to be used. SELECT MUX 68 enables selection among a variety of ordnance to be used. For example, in a system comprising chaff/decoy, rocket or a number of different sizes and types of ordnance, selection can be made as to which weapon to use. Further, inventory control can be implemented to monitor and replenish weapons as needed. MCDRL control module 64 includes connections to elevation 70 and traverse 72 drive options to accommodate systems which include these features. Particularly, the select MUX 68 module is connected to cartridges 69, which include decoy/chaff and rocket cartridges. Intermediate connectors 71 are directly connected to cartridge I/F (Interface) 73. I/F 73 are in turn connected to Select MUX 68. Accordingly, MCDRL launcher control module 64 is modular in design and provides light weight, low cost and small size and can be tailored to platform needs. 
     FIG. 11 depicts a launch control unit of the MCDRL electrical system architecture. The unit includes a local maintenance panel having a two-way communication with MCDRL launch control unit 66. Local maintenance panel 74 provides confirmation commands, status and power within the system, and communicates this information to launch control unit 66. Further, remote launch control panel(s) 76, which is essentially a CIC (command and information center) and bridge, is connected to MCDRL launch control unit 66. Electronic warfare system(EWS) 78 is also connected to MCDRL launch control unit 66. Inertial navigation system (INS) 84 is also connected to MCDRL launch control unit 66 and provides an optional feature. Furthermore, MCDRL Launch Control Unit 66 is connected to Multipurpose chaff/decoy Launcher 86. Multipurpose Launcher 86 is also connected to chaff/decoy cartridges 88 and rocket cartridge 94. Connectors 96 include unique interface (I/F) elements with non-contact surface which provide power transmission from Ships power 60 to canisters containing chaff/decoy cartridges 88 or rocket cartridge 94. Particularly, connectors 96 are designed to overcome unreliable connection between electrical systems due to a ship&#39;s environment which is highly corrosive. Connectors 96 comprise a non-contact surface. A transformer generates an electromagnetic field across a separation space to thereby transmit electric current and eliminates undesirable surface contacts. The MCDRL electrical system provides an improved support system in an overall ship defense system comprising hardkill and softkill missions. It is sufficiently flexible to provide a multi-mission capability and is cost effective with a light weight design. As indicated hereinabove, the system is modular and can meet the requirements for different launcher systems and platforms. 
     FIG. 12 is a detail of MCDRL Launch Control Unit (LCU) 98. It comprises selectable EWS Interface (I/F) module 104, INS I/F module 106, and Power Supply/Monitor module 108. Further, a CIC (Command Information and Control) Remote Launch Enable Panel (RLEP) 112 is connected to LCU 98. A bridge RLEP 114 is also connected to LCU 98. Selectable EWS I/F Module 104 as well as INS I/F module (optional) 106 are connected to LCU 98 via backplane bus 118. Selectable EWS I/F 104 is directly connected to EWS input 120 and INS I/F module 106 is directly connected to INS input 122. MCDRL LCU 98 includes a user configurable input/output and a high performance low cost CPU. These features enable the utilization of off-the-shelf modules with low cost and small size advantages. 
     An exemplary operational sequence may be reviewed in conjunction with the embodiment shown in FIG. 4. As discussed hereinabove, FIG. 4 is an embodiment of a multiple launcher with fixed tube launchers and an elevatable launcher consisting varying size rocket/missile rounds. As shown in FIG. 4, inclined decoy/chaff launchers 24 are removably mounted on side mount 26. Launchers 24 are inclined relative to one another as shown. Side mount 26 is removable and adaptable to the size and structural requirements of launchers 24. Moreover, unlike prior practice, the present invention enables the refurbishment and unlimited re-use of launchers 24. More particularly, the present invention enables a configuration in which different sizes and dimensions of launchers 24 may be assembled and installed on side mount 26 to meet mission requirements. 
     When a fire command is issued by the user, MCDRL Launch Control Unit 66 is activated (Refer to FIG. 10). The message is passed to MCDRL control module 64. Hereafter, the Select MUX 68, Elevation drive module 70 and traverse drive module 72 are activated. Particularly, Elevation 70 and traverse 72 drives are activated to receive user instructions and to respond accordingly. More particularly, the user may choose which decoy/cartridge to fire by selecting the type of ordinance, for example rocket cartridge 69. This selection is made possible by Select MUX 68 unit , which is directly connected to cartridge I/F 73. 
     More specifically, with reference to FIG. 11, Remote Launch control panel 76 is activated and launch control command is sent to MCDRL launch control unit 66. Further, if electronic warfare is anticipated or this option exercised, Electronic Warfare System (EWS)78 is activated and Launch Commands such as status, loadout and attitude data are sent to MCDRL launch control unit 66. Similarly, Inertial Navigation System (INS) 84 option may be exercised if navigation and attitude data is required to be entered into the MCDRL launch control unit 66. A fire and position loadout status is communicated between MCDRL control unit 66 and Multi-Purpose Chaff/Decoy/Rocket Launcher(MCDRL) 86. From MCDRL 86, the fire command as issued by the user is transmitted to the Cartridge of choice, i.e., Chaff/Decoy Cartridge 88 or Rocket cartridge 88. The choice of which one to fire is noted and isolated to be directed to the proper cartridge by means of fire commands (CMDS) identification connections 96. A local maintenance panel 74 is used to feed back MCDRL launch control unit 66. For example, status and power conditions are fed back to MCDRL launch control unit 66 via a connections which confirms an original command as issued by the user. Accordingly, a simultaneous selection can be made to fire chaff/Decoy cartridge in launcher 24 while at the same time choosing to fire any one of tube clusters 32 in launcher housing 30. Further, Launcher housing 30 may be elevated and/or traversally driven to orient the rockets or missiles in launch tube clusters 32 as needed while at the same time selection and firing of Chaff/decoy cartridges in tube 24 is executed.

The tubes may be mounted on a fixed platform or a trainable platform. Designation B shows a single cell housing canister. In contrast Designations C, D and E show Pods in which a variety of launch tubes are stored to provide multiple storage and containment. Designation F shows a trainable/elevatable rectangular pods. One of the launcher housings includes a number of single cell launch tubes which contain rockets or missiles. Another rectangular box is installed piggy-back containing tube launchers which may be used to launch decoys/chaff. Designation G shows trunnion mounted tube launchers as well as fixed angle base-mounted decoy tube launchers. This arrangement enables the training of the tube launchers to deploy ordinance which may require more precise target placement. Designation H shows a variation of the embodiment in Designation F, wherein the piggyback launcher is omitted. Designation I shows exemplary decoy robot, in a deployed position, with stabilizer fins extended. During storage, the fins are folded inside a launch tube. A launch platform is shown in Designation J, from which a decoy robot of the type shown in Designation I may be launched. 
     Designation K shows a variation of Designations F, G and H with a trainable/elevatable set of launch tubes. Particularly, the configuration in Designation K provides protection for the launcher tubes by means of an extended trunnion. 
     Designation L shows a vertical base having a rectangular cross-section with gusset plates as stiffeners for the sides. 
     Designations M and N show different types of arrangements in which decoy tubes and launchers are arranged to meet specific mission requirements. 
     Designations O, P, Q, R, S, T, U depict piece parts which provide training and elevation of a launch system. A typical system may include a foundation which is attached to a fixed angle base or a training mechanism. Further, a typical system may include a trunnion with or without an extension. Multi-pack launchers such as the ones shown in Designations V and W may be supported on a fixed angle base or a training mechanism as required. 
     Designations X and Y depicts cards which can be used to control the MCDRL launch control functions which monitor the cooperation and operation of the different components. The card file is expendable to accommodate special features and controls as dictated by mission requirements. 
     Accordingly, as Shown in FIG. 9, the present invention provides modularity and expandability to meet a variety of mission requirements and specifications. The modularity in packaging and design enables options to add future expansions. Thus, a chaff/decoy launcher may be upgraded to include launchers for missiles and rockets by making minimum changes to the existing system. 
     While a preferred embodiment of the present invention has been shown arid described herein, it will be appreciated that various changes and modifications may be made therein without departing from the spirit of the invention as defined by the scope of the appended claims.
