Description
Background of the Invention
This invention relates in general to missile launching and more particularly, to methods for transferring a missile to a launcher.
In the past, the conventional method for reloading a vertical launching system (VLS) with missiles from a supply ship has required numerous, time-consuming manhandling, repositioning, and preparatory operations carried out in succession on the deck of a combatant ship being reloaded.
Summary of the Invention
It is therefore one object of this invention to eliminate many of these operations or perform them on a supply ship where they will take place off the critical path.
It is another object to reduce the time required to reload a VLS.
The objects of the invention are achieved by a method of loading a cell of a VLS missile launcher with a canistered missile from a supply ship wherein the canistered missile is transferred from the supply ship to a fixed guide on the deck of the combatant ship, upended in the guide, moved away to a position over the cell of the missile launcher, and then lowered into the cell. A canistered missile is a missile sealed in a canister which serves as both a launch tube and shipping container for the missile.
Advantages of this invention include the capability of achieving canistered missile loading rates of 20 missiles per hour, and the reduced chance of injury to personnel or damage to the missile from rough seas because manhandling of the loose canister or other heavy equipment on deck is eliminated.
Additional advantages and features will become more apparent as the subject invention becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
Brief Description of the Drawings
FIGS. 1 to 8 show the acts making up the various steps in an embodiment of the method of loading a cell of a VLS missile launcher on a combatant ship with a canistered missile from a supply ship in accordance with the invention.
Detailed Description
Referring to FIGS. 1 to 8, a method of loading a cell of a VLS missile launcher on a combatant ship with a canistered missile from a supply ship includes a first step 1 in which the canistered missile is transferred from the supply ship to a fixed guide on the deck of the combatant ship.
While step 1 may take a variety of forms, conveniently it may take the form of conveying the canistered missile 11 from the supply ship (not shown) to the combatant ship 13 by means of a ropeway 15 using a first strongback 17 (as shown in FIG. 1); positioning the canistered missile 11 on the ropeway 15 over the fixed guide 19 (as shown in FIG. 2); and lowering the ropeway 15 to deposit the canistered missile 11 in the guide 19 (as shown in FIG. 3).
In step 2, the canistered missile is upended in the guide.
While step 2 may take a variety of forms, conveniently it may take the form of connecting a suspension cable 21 from a boom winch 23 to one end of the canistered missile 11 by means of a second strongback 25 (as shown in FIG. 3); disconnecting the first strongback 17 from the canistered missile 11 (as shown in FIG. 4); raising the ropeway 15 and returning the first strongback 17 to the supply ship (as shown in FIG. 4); and hoisting the second strongback 25 by means of the boom winch 23 to upend the canistered missile 11 in the guide 19 (shown in FIG. 4).
Next, step 3 is performed whereby the upended canistered missile is moved away from the guide to a position over the cell of the missile launcher.
While step 3 may take a variety of forms, conveniently it may take the form of attaching a pair of lines 27, 29 to diagonally opposite corners of a collar 31 at the base of the upended canistered missile 11 (as shown in FIGS. 5 and 6); routing the free ends of the pair of lines 27, 29 through a cell guide 33 mounted in the cell 35 and around one-way rollers 37, 39 at the corners of the missile launcher 41 (as shown in FIGS. 5 and 6); and moving the boom 43 to position the upended canisterd missile 11 over the cell 35 of the missile launcher 41 (as shown in FIG. 7).
Finally, in step 4 the canistered missile is lowered into the cell.
While step 4 may take a variety of forms, conveniently it may take the form of rotating the canistered missile 11 on the suspension cable 21 by means of the pair of lines 27, 29 to align the canistered missile with the cell guide 33 (as shown in FIG. 7); lowering the canistered missile 11 into the cell guide 33 by means of the boom winch 23 (as shown in FIG. 8); and decoupling the collar to allow the canistered missile 11 to be lowered though the collar and cell guide 33 to seat within the cell 35 of the missile launcher 41 (as shown in FIG. 8).
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
Claims
What is claimed as new and desired to be secured by Letters Patent of the United States is:
1. A method of loading a cell of a vertical launching system missile launcher on a combatant ship with a canistered missile from a supply ship comprising the steps of: (a) transferring the canistered missile from the supply ship to a fixed guide on the deck of the combatant ship; (b) upending the canistered missile in the guide; (c) moving the upended canistered missile away from the guide to a position over the cell of the missile launcher; and (d) lowering the canistered missile into the cell.
