In one exemplary embodiment, the watercraft 300 has an upper deck 310, and a lower deck 320. As shown, the upper deck 310 and the lower deck may be separated by a distance of H. The distance H may be about 4 ft to about 5 feet or more. As shown, the upper deck 310 has a substantially rectangular opening 315 for receiving the modular missile launching assembly 100. The dimensions of the opening 315 are commensurate with the dimensions of the missile launching assembly. FIG. 3A includes an arrow 333 representing the direction of travel. Based on the direction of travel, the upper surface surrounding the hole/opening 315 may be divided into four zoned surfaces, i.e., a forward end surface 311, an aft end surface 312, a starboard side surface 313, and a port side surface 314, as shown by the hatched patterns in FIG. 3A. The hatched patterns are for illustrative purposes only, and do not signify material differences on the upper deck 310. FIG. 3A shows the watercraft having a length L. In one embodiment, the length L may be about 30 feet to about 150 feet or longer.
FIG. 3B is a perspective view of a modular missile launching assembly 100, as outlined above, attached to a watercraft 300, also outlined above. The assembly 100 is attached to the watercraft 300 by being mounted into the substantially rectangular opening 315. When the missile assembly 100 is inserted, the outer lip portion 130 shown in FIGS. 1-2C contacts the upper deck surface surrounding the opening 315. The modular missile launching assembly 100 may be securely attached to the watercraft 300 by clamps, bolts, screws, electromechanical devices, and combinations thereof. For example, an electromechanical device having a solenoid and a connected plunger may be used to move bolts into a securing position, such as the receiving openings 139 on the outer lip 130 shown in FIGS. 1A and 2C. Alternatively, screws may be manually threaded through the openings. In yet another exemplary fastening arrangement, a combination of electromechanical and manual fastening devices may be used. Any of the above outlined arrangements expedite the installation of the modular missile launching assembly onto the watercraft. In fact, this modular missile launching assembly may be swapped out to another watercraft in approximately 20 minutes, using only two men and a crane.
The opening 315 in the upper deck may be oriented in any desired manner to allow for the insertion of the modular missile launching assembly 100 in any desired orientation. In the exemplary embodiment shown in FIG. 3A, the modular missile launching assembly is mounted so that the first outer lip portion 131 is aligned with the forward end surface 311, the second outer lip portion 132 is aligned with the aft end surface 312, the third outer lip portion 277 is aligned with the starboard side surface 313, and the fourth outer lip portion 134 is aligned with the port side surface 314.
FIG. 3B shows the modular missile launching assembly 100 with the launching lid 135 in an open position. It should be noted that in the closed position, the missile launching assembly keeps missile fumes within the container, thereby reducing the possibility of detecting missile signatures. When the modular missile launching assembly is attached to a watercraft 300, as shown in FIG. 3B, the modular missile launching assembly 100 projects downward into the space between the two decks. As outlined above, FIG. 1A shows the container 101 having a height A, a width B, and a length C. In one exemplary embodiment, the height A may be about 12 inches to about 20 inches. According to the exemplary embodiment, the width B may be about 30 inches to about 60 inches, and the length C may be about 60 inches to about 84 inches. Because the upper deck 310 is separated from the lower deck by a distance of about 48 inches to about 60 inches, the assembly 100 takes up little of the overhead space, leaving the payload bay with a majority of its original capabilities. Depending on the embodiment, clearance between the lower deck 320 and the base plate 120 of the container 101 may be about 28 inches to about 48 inches.
FIG. 4 is a flowchart showing a method 400 of replaceably arming a watercraft, according to an embodiment of the invention. The steps involved in the method 400 of arming a watercraft have been outlined above in detail in the description with respect to FIGS. 1A-3B. Step 410 is the providing of a watercraft 300 having one or more decks, including an upper deck 310 having a substantially rectangular opening 315, as outlined above with respect to FIG. 3A. Step 420 is the providing of a modular missile launching assembly 100, as outlined above with respect to FIGS. 1A, 1B, 2A, 2B, and 2C.
