Abstract

A method for ocean surface delivery of ordnance and clearing of explosive mines and obstacles from a navigable sea channel includes the step of providing quantities of ordnance adapted to survive impact and prolonged immersion in sea water and to arm in response to release from a mobile ocean surface vehicle and to pressure actuation upon submersion to a desired depth in sea water and then to detonate in response to receiving a preselected signal transmitted to the ordnance from a standoff location. The method also includes the step of delivering the quantities of ordnance from a mobile ocean surface vehicle toward multiple sites in a navigable sea channel containing obstacles and explosive mines therein so as to cause arming of the ordnance followed by impact thereof with the navigable sea channel and submersion and emplacement thereof at the multiple sites in the navigable sea channel. The ocean surface delivery method further includes the step of transmitting the preselected signal to and receiving the preselected signal by the emplaced armed ordnance so as to cause detonation thereof and the simultaneous synergistic destruction of the obstacles and explosive mines contained in the navigable sea channel. The method also includes the step of marking an amphibious path through the cleared navigable sea channel.

Claims

1. A method for ocean surface delivery of ordnance and clearing of explosive mines and obstacles from a navigable sea channel, said method comprising the steps of:

(a) providing quantities of ordnance adapted to survive impact and prolonged immersion in sea water and to arm in response to release from a mobile ocean surface vehicle and to pressure actuation upon submersion to a desired depth in sea water and then to detonate in response to receiving a preselected signal transmitted to the ordnance;

(b) delivering the quantities of ordnance from a mobile ocean surface vehicle toward multiple sites in a navigable sea channel containing obstacles and explosive mines so as to cause arming of the quantities of ordnance by release from the mobile ocean surface vehicle and submersion to desired depth in the sea channel followed by emplacement thereof at the multiple sites in the navigable sea channel;

(c) transmitting the preselected signal in the form of an encrypted magnetic signal to the emplaced quantities of armed ordnance; and

(d) receiving the preselected signal at the emplaced quantities of armed ordnance so as to cause simultaneous detonation thereof and destruction of the obstacles and explosive mines in the navigable sea channel.

2. The method of claim 1 wherein the quantities of ordnance are delivered from a mobile air cushion vehicle equipped with a multiple mine laying apparatus.

3. The method of claim 1 wherein the quantities of ordnance are delivered from multiple mine laying apparatus on the mobile ocean surface vehicle.

4. The method of claim 1 wherein the preselected signal is transmitted so that said signal is received by the emplaced quantities of armed ordnance, substantially simultaneously.

5. The method of claim 1 wherein the preselected signal is transmitted from a standoff control station.

6. The method of claim 5 wherein the preselected signal is transmitted so that said signal is received by the emplaced quantities of armed ordnance substantially simultaneously.

7. The method of claim 1 wherein the preselected signal is received so that the emplaced quantities of armed ordnance are detonated substantially simultaneously.

8. A method for ocean surface delivery of ordnance and clearing of explosive mines and obstacles from a navigable sea channel, said method comprising the steps of:

(a) providing quantities of ordnance adapted to survive impact and prolonged immersion in sea water and to arm in response to release from a mobile ocean surface vehicle and to pressure actuation upon submersion to a desired depth in sea water and then to detonate in response to receiving a preselected signal transmitted to the ordnance;

(b) delivering the quantities of ordnance from a mobile ocean surface vehicle toward multiple sites in a navigable sea channel containing obstacles and explosive mines so as to cause arming of the quantities of ordnance by release from the mobile ocean surface vehicle and submersion to desired depth in the sea channel followed by emplacement thereof at the multiple sites in the navigable sea channel;

(c) delivering global positioning system markers with the quantities of ordnance to mark an amphibious path through the cleared navigable sea channel;

(d) transmitting the preselected signal to the emplaced quantities of armed ordnance; and

(e) receiving the preselected signal at the emplaced quantities of armed ordnance so as to cause simultaneous detonation thereof and destruction of the obstacles and explosive mines in the navigable sea channel.

9. The method of claim 8 wherein the preselected signal is an encrypted magnetic signal.

10. A method for ocean surface delivery of ordnance and clearing of explosive mines and obstacles from a navigable sea channel, said method comprising the steps of:

(a) providing quantities of ordnance adapted to survive impact and prolonged immersion in sea water and to arm in response to release from a mobile ocean surface vehicle and to pressure actuation upon submersion to a desired depth in sea water and then to detonate in response to receiving a preselected signal transmitted to the ordnance;

(b) delivering the quantities of ordnance from a mobile ocean surface vehicle toward multiple sites in a navigable sea channel containing obstacles and explosive mines so as to cause arming of the quantities of ordnance by release from the mobile ocean surface vehicle and submersion to desired depth in the sea channel followed by emplacement thereof at the multiple sites in the navigable sea channel;

(c) transmitting the preselected signal from a standoff control station to the emplaced quantities of armed ordnance; and

(d) receiving the preselected signal at the emplaced quantities of armed ordnance so as to cause simultaneous detonation thereof and destruction of the obstacles and explosive mines in the navigable sea channel;

(e) the preselected signal being a common magnetic signal transmitted so that said signal is received by all the emplaced quantities of armed ordnance substantially simultaneously.

11. The method of claim 10 wherein the preselected signal is an encrypted magnetic signal.

12. A method for ocean surface delivery of ordnance and clearing of explosive mines and obstacles from a navigable sea channel, said method comprising the steps of:

(a) providing quantities of ordnance adapted to survive impact and prolonged immersion in sea water and to arm in response to release from a mobile ocean surface vehicle and to pressure actuation upon submersion to a desired depth in sea water and then to detonate in response to receiving a magnetic signal transmitted to the ordnance from a standoff control station;

(b) delivering the quantities of ordnance from a multiple mine laying apparatus on a mobile air cushion vehicle toward multiple sites in a navigable sea channel containing obstacles and explosive mines so as to cause arming of the quantities of ordnance by release from the mobile ocean surface vehicle and submersion to desired depth in the sea channel followed by emplacement thereof at the multiple sites in the navigable sea channel;

(c) transmitting the magnetic signal from the standoff control station so that said signal is received by the emplaced quantities of armed ordnance substantially simultaneously; and

(d) receiving the magnetic signal simultaneously at the emplaced quantities of armed ordnance so as to cause simultaneous detonation thereof and synergistic destruction the obstacles and explosive mines in the navigable sea channel.

13. The method of claim 12 further comprising:

delivering global positioning system markers with the quantities of ordnance to mark an amphibious path through the cleared navigable sea channel prior to detonation.
