Abstract

A non-lethal naval vessel interdiction weapon is provided. The non-lethal naval vessel interdiction weapon includes a hydrodynamic hull, guidance and delivery systems housed in the hydrodynamic hull with the delivery system being controllable by the guidance system to drive a naval vessel impeding payload toward a target and a deployment system. The deployment system is configured to prepare the hydrodynamic hull for payload deployment and to deploy the naval vessel impeding payload toward the target following hull preparation.

First claim

What is claimed is:

1. A non-lethal naval vessel interdiction weapon, comprising:
a naval vessel impeding payload;
a hydrodynamic hull comprising a nosecone section and a payload section aft of the nosecone section and in which the naval vessel impeding payload is at least partially disposable;
guidance and delivery systems housed in the hydrodynamic hull with the delivery system being controllable by the guidance system to drive the naval vessel impeding payload toward a target; and
a deployment system configured to prepare the hydrodynamic hull for payload deployment whereby the nosecone section is separated from the payload section to expose the naval vessel impeding payload and to deploy the naval vessel impeding payload from the payload section and toward the target following hull preparation.

2. The non-lethal weapon according to claim 1 , wherein the hydrodynamic hull, the guidance, delivery and deployment systems and the naval vessel impeding payload are operable underwater.

3. The non-lethal weapon according to claim 1 , further comprising a power supply and a processing unit respectively housed in the hydrodynamic hull for respective use by at least one of the guidance, delivery and deployment systems.

4. The non-lethal weapon according to claim 1 , wherein at least the guidance and delivery systems are operable in low-power or high-power modes.

5. The non-lethal weapon according to claim 1 , wherein the naval vessel impeding payload comprises:
a harpoon attachable to the target; and
an anchoring element coupled to the harpoon and configured to anchor the target with the harpoon attached thereto.

6. A non-lethal naval vessel interdiction weapon, comprising:
a hydrodynamic hull;
guidance and delivery systems housed in the hydrodynamic hull with the delivery system being controllable by the guidance system to drive a naval vessel impeding payload toward a target; and
a deployment system configured to prepare the hydrodynamic hull for payload deployment and to deploy the naval vessel impeding payload toward the target following hull preparation, wherein:
wherein the naval vessel impeding payload comprises a harpoon attachable to the target and an anchoring element coupled to the harpoon and configured to anchor the target with the harpoon attached thereto, and
the harpoon comprises:
a barrel which is stowed in a pre-deployment condition in a firing barrel of the deployment system;
a flange;
a barbed front end which extends forwardly from the barrel and which is forcibly injectable through a hull of the target upon harpoon deployment such that the flange abuts with the hull of the target and with the barbed front end impeding harpoon withdrawal.

7. The non-lethal weapon according to claim 6 , wherein the flange is configured to seal the hull of the target and the barbed front end comprises barbs which are extendable post-injection.

8. The non-lethal weapon according to claim 5 , wherein the anchoring element comprises:
a sea anchor; and
a tether coupling the sea anchor to the harpoon.

9. A non-lethal weapon for small vessel or large vessel interdiction, comprising:
a hull comprising a tail, a nosecone, a payload section interposed between the tail and the nosecone and a cutting system operable to separate the nosecone from the payload section;
guidance and delivery systems housed in the hull with the delivery system being controllable by the guidance system to drive the payload section toward a target;
a payload housed in the payload section and comprising a harpoon attachable to the target upon deployment thereof and an anchoring element coupled to the harpoon and configured to anchor the target with the harpoon attached thereto; and
a deployment system configured to operate the cutting system and to deploy at least the harpoon toward the target following nosecone separation,
the guidance, delivery and deployment systems being configured for engagement in response to issuance of a tactically useful hostile intent assessment alert.

10. The non-lethal weapon according to claim 9 , wherein the hull, the guidance, delivery and deployment systems and the payload are operable underwater.

11. The non-lethal weapon according to claim 9 , further comprising a power supply and a processing unit respectively housed in the hull for respective use by at least one of the guidance, delivery and deployment systems.

12. The non-lethal weapon according to claim 9 , wherein at least the guidance and delivery systems are operable in low-power or high-power modes.

13. The non-lethal weapon according to claim 9 , wherein the harpoon comprises:
a barrel which is stowed in a pre-deployment condition in a firing barrel of the deployment system;
a flange;
a barbed front end which extends forwardly from the barrel and which is forcibly injectable through a hull of the target upon harpoon deployment such that the flange abuts with the hull of the target and with the barbed front end impeding harpoon withdrawal from the hull of the target.

14. The non-lethal weapon according to claim 13 , wherein the flange is configured to seal the hull of the target.

15. The non-lethal weapon according to claim 13 , wherein the barbed front end comprises barbs which are extendable post-injection.

16. The non-lethal weapon according to claim 9 , wherein the anchoring element comprises:
a sea anchor; and
a tether coupling the sea anchor to the harpoon.

17. The non-lethal weapon according to claim 9 , wherein the deployment system comprises:
a firing barrel in which the harpoon is stowed in a pre-deployment condition;
a charge accommodated within a rear end of the firing barrel.

18. The non-lethal weapon according to claim 17 , wherein the deployment system further comprises an additional charge at an exterior of the firing barrel.
