The present invention relates to a removable weapon system, specifically to a weapons system that is magnetically engaged to a platform.
Weapon systems are typically permanent installations on a platform, they are physically mounted to provide an integrated system on a hull, deck or platform.
According to an aspect of the present invention, there is provided a removable weapon system for a platform which comprises
The switchable magnet may be an electromagnet, magnetic chuck (magnetic base), switchable permanent magnet, magnet array or superconducting magnet.
The magnetic chuck, may be a permanent magnet with comprises a means of moving the magnetic field into and out of alignment, such as for example by rotation of the magnets or moving the magnets to a different alignment or away from the platform surface to reduce the magnetic field exerted on the second mount.
The magnetic chuck may have the permanent magnets moved into and out of alignment by any means, such as, for example a motor, hydraulics, manual levers.
The permanent magnets in the magnetic chuck may be aligned linearly, in rings, provided that they may be moved in and out of alignment to change the magnetic field.
Electromagnets are well known, and may provide a facile means of switching the magnetic field on and off by control of the electrical flow within the electromagnetic coil. Superconducting magnets require cooling, and may have electrical energising, in a similar fashion to electromagnets, to increase their magnetic field.
In a highly preferred arrangement the first mount on the weapons system comprises the reversible engagement device. The reversible engagement may be locked into position, by controlling the ability to switch the magnet between energised and un-energised states. This allows the weapon system to be readily located on more than one platform, and further allows the weapon system to be located in more than one location on a large platform, such that it may be dependent on where the weapon system is required, rather than having only one dedicated site.
The second mount may preferably be a non-austenitic steel, more preferably ferrous material. The second mount may be a dedicated steel plate or block or the second mount may be the platform.
The platform may be a vehicle, vessel, craft or land base. The land base may be a dock, building, installation.
Many platforms, ships, boats, land vehicles are built from ferretic steels, which allows the removable weapon system to be readily located anywhere on the platform. Preferably, the second mount is the deck, hull, chassis, loading area, of the platform, to provide flexibility of location of the removable weapon system.
The second mount may be a specifically designed receiving mount which is affixed to the platform, the where the weapons system is to be located. The receiving mount may be a flat steel plate or block of steel. The receiving mount may be required where the platform is manufactured from materials that are not attracted to magnets, such as example a composite material, aluminium or other non-ferrous metals.
The weapon system may be any system that launches or dispenses payloads, or provides a launch platform for safety or rescue equipment. The weapons system may be a gun, such as a small calibre gun 5.56 mm to 20 mm, medium calibre gun 20-40 mm, large calibre guns 60-155 mm, Remote Weapons Systems (RWS), gun systems which may comprise more than one gun of different calibres, grenade launchers, mortar tubes, torpedo launchers, countermeasure launcher, life raft launcher, situational awareness launcher. Countermeasures may be for sea, land or air, such as anti-torpedo launchers, chaff, IR, smoke devices, depth charges etc. Situational launchers may be drones, sensors etc.
In one example, a mid-sized watercraft may be required to perform different tasks, and so may be fitted with a gun on one mission. On a second mission the gun may be removed and refitted to assist in a countermeasure exercise.
In a further example a large ship may have need for a close combat role, and require means to neutralise a threat, a close-quarter small calibre gun may be retrieved from its stowed position, and located at the required position on the deck of the ship.
Where the weapon system comprises live payloads, there may be a safety interlock to prevent disengagement of the reversible engagement device of the first mount on the weapon system from the second mount, whilst the weapon system is operational. The interlock may be a physical link between the switchable magnet and the weapon system, such as for example physical interlocks, such as, for example, castell keys or the likes. The interlock may be an electronic link, which prevents operation of the switchable magnet, such as for example the fire control system or combat system may be electronically linked to the switchable magnet, to prevent deactivation of the magnet, and its attempted removal. The interlock may be a combination of physical and electronic safety interlocks.
The safety interlock may further prevent disengagement of the weapon system from the mount when there is ammunition, ie a live payload, store present in the weapon system, such as for example where a shell is loaded in the breach of said barrel. The ammunition ie shell would be required to be removed from the barrel, before the switchable magnet is capable of being deactivated, by the use of either physical and/or electronic interlocks, so as to allow appropriate safe removal of the weapon system from the platform.
The first and second mounts may comprise at least one cooperatively locating lug and void, such as to increase the surface area between the first and second mounts, thereby increasing the magnetic force exerted there between. The lug and void may co-operative interdigitated elements, stepped features etc. Preferably both the first and second mounts are substantially flat, to allow the weapon system to be located on any flat surface.
Many weapon systems require electrical power and/or data transfer between the weapon system and the associated combat system (CMS) on the platform. The power and data may be transferred between the platform and the weapon system via the first and second mounts.
The first mount may comprise a first region which comprises the switchable magnet, said first region being brought into abutment with the second mount. The first mount may comprise a second region, which comprises the mechanical devices, electrical supply, data ports for connection to the weapon system. In a preferred arrangement the weapon system may be directly fixed ie bolted to the second region. The electrical, hydraulic, data systems may be operably linked between the platform and the weapon system via the second region, or directly through the switchable magnet.
Embodiments of the invention will now be described by way of example only with reference to the figures, in which:

The second region 25 is integrally linked with the first region 24, The second region comprises the magnets, and abuts and forms a mating union by magnetic force with the deck 21.
In one sequence of operation, it may require:

As an example a circular base with a radius of 1.2 m would allow a retention force of up to 130 tonnes. This is 10× the maximum expected recoil load of a 40 mm cannon, therefore allowing the connection and safe operation of many common existing cannons as weapon systems that can be used with a switchable magnet in the first mount.
