Abstract : This improved propellant embedded marine anchor includes an emergency release device used to safely separate the anchor projectile from the gun assembly for the purpose of disarming the system when a misfire occurs. The anchor projectile is connected to a pair of anchor link rods, each of which are attached to rod guides that are locked in place by means of respective rotatable sear pins. The sear pins are each attached to a lever mechanism which in turn is attached to a release line. An upward force on the release line will cause the sear pins to be rotated releasing the anchor link rods and allowing the anchor projectile to fall away, and the drive piston and explosive cartridge to drop free from the gun barrel, wherein seawater will flood the gun barrel and penetrate the primer for completely disarming the anchor system.
