Abstract
Abstract This disclosure relates to decoy rounds for launching from launcher systems which may be installed aboard a ship or the like, or which may be of a portable type. The decoy rounds provide a protective cover for craft such as war ships, against homing devices operating upon infrared or microwave-reflected energy or against craft utilizing sound navigation and ranging systems. The decoy rounds contain one or more bundles of either RF chaff, infrared energy creating pellets, or bubble creating pellets, or any combination thereof, and are provided with a launch charge and a dispersion charge for each of the bundles of decoy material therein.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
40 words
A decoy round adapted to be fired from a launcher comprising: a launch charge, a plurality of RF chaff bundles, a bundle containing material capable of creating infrared energy, and a plurality of explosive charges for individually dispersing said bundles.
Claim 2
Dependent Claim
40 words
A decoy round adapted to be fired from a launcher comprising: a launch charge, a plurality of RF chaff bundles, a bundle containing material capable of creating infrared energy, and a plurality of explosive charges for individually dispersing said bundles.
Claim 3
Dependent Claim
53 words
The decoy round defined in claim 1, wherein said launch charge, said plurality of RF chaff bundles, said bundle containing material capable of creating infrared energy, and said plurality of explosive charges are positioned longitudinally within a housing, said plurality of explosive charges being separated from one another by one of said bundles.
Claim 4
Dependent Claim
61 words
A decoy round for sonar confusion comprising: means for launching said round, means for dispensing a portion of said round above surface of the water, means for sinking the remainder of said round beneath the water surface, and means for dispensing the remainder of said round beneath the water surface, said round including means capable of creating a sonar signal relector.
Claim 5
Dependent Claim
61 words
A decoy round for sonar confusion comprising: means for launching said round, means for dispensing a portion of said round above surface of the water, means for sinking the remainder of said round beneath the water surface, and means for dispensing the remainder of said round beneath the water surface, said round including means capable of creating a sonar signal relector.
Claim 6
Dependent Claim
97 words
The decoy round defined in claim 3, wherein said means for launching said round includes a propellant charge and a fuze means for igniting said charge; wherein said round dispensing means includes a pair of explosive charges and fuze means, said last mentioned fuze means includes a pair of delay fuzes and a pair of fuzes for igniting said pair of explosive charges, one of said delay fuzes interconnecting said explosive charge igniting fuzes, the other of said delay fuzes and said propellant charge igniting fuze means being operatively connected such that each are activated substantially simultaneously.
Claim 7
Dependent Claim
36 words
The decoy round defined in claim 3, wherein said material in each of said portions of said round includes at least an amount of lithium hydroxide, whereby contact of said lithium hydroxide with water generates bubbles.
Claim 8
Dependent Claim
26 words
The decoy round defined in claim 3, wherein said material in at least said portion of said round dispensed under water includes at least lithium powder.
Claim 9
Dependent Claim
55 words
A decoy round adapted to be fired from a launcher comprising: a launch charge, means for igniting said launch charge, dispersible decoy material, explosive material for dispersing said decoy material, fuse means for igniting said explosive material, and means for substantially simultaneously actuating said launch charge igniting means and said explosive material igniting fuse means.
Claim 10
Dependent Claim
55 words
A decoy round adapted to be fired from a launcher comprising: a launch charge, means for igniting said launch charge, dispersible decoy material, explosive material for dispersing said decoy material, fuse means for igniting said explosive material, and means for substantially simultaneously actuating said launch charge igniting means and said explosive material igniting fuse means.
Claim 11
Dependent Claim
20 words
The decoy round defined in claim 7, wherein said dispersible decoy material includes at least one bundle containing RF chaff.
Claim 12
Dependent Claim
24 words
The decoy round defined in claim 7, wherein said dispersible decoy material includes at least one bundle containing material capable of creating infrared energy.
Claim 13
Dependent Claim
26 words
The decoy round defined in claim 7, wherein said dispersible decoy material includes at least one bundle containing means capable of creating a sonar signal reflector.
