A system for attaching a disposal charge to underwater ordnance, comprising: attaching means for attaching the disposal charge to underwater ordnance, whereby said attaching means is configured to be fixed to the disposal charge; a trigger mechanism for triggering activation of the attaching means; and a coupling system configured to be mounted to a deployment system for releasably coupling the attaching means to the deployment system, whereby said coupling system comprises a first portion configured to be rigidly mounted to the deployment system, a second portion on which the attaching means is releasably coupled, the system being characterized in that said coupling system furthermore comprises flexible coupling means to flexibly couple said first portion and second portion and releasable coupling means to rigidly couple said first portion and second portion, said coupling system being configured to be in: a first configuration in which the first portion and the second portion are rigidly coupled by said flexible coupling means and by said releasable coupling means; or a second configuration in which the first portion and the second portion are only flexibly coupled by said flexible coupling means, the system comprises means for controllably changing the configuration of the coupling means from the first configuration to the second configuration by releasing of the releasable coupling means, wherein the trigger mechanism is activated upon changing the configuration of the coupling means from the first configuration to the second configuration. attaching means for attaching the disposal charge to underwater ordnance, whereby said attaching means is configured to be fixed to the disposal charge; a trigger mechanism for triggering activation of the attaching means; and a coupling system configured to be mounted to a deployment system for releasably coupling the attaching means to the deployment system, whereby said coupling system comprises a first portion configured to be rigidly mounted to the deployment system, a second portion on which the attaching means is releasably coupled, the system being characterized in that said coupling system furthermore comprises flexible coupling means to flexibly couple said first portion and second portion and releasable coupling means to rigidly couple said first portion and second portion, said coupling system being configured to be in: a first configuration in which the first portion and the second portion are rigidly coupled by said flexible coupling means and by said releasable coupling means; or a second configuration in which the first portion and the second portion are only flexibly coupled by said flexible coupling means, a first configuration in which the first portion and the second portion are rigidly coupled by said flexible coupling means and by said releasable coupling means; or a second configuration in which the first portion and the second portion are only flexibly coupled by said flexible coupling means, the system comprises means for controllably changing the configuration of the coupling means from the first configuration to the second configuration by releasing of the releasable coupling means, wherein the trigger mechanism is activated upon changing the configuration of the coupling means from the first configuration to the second configuration.
