An extended range, enhanced lethality 40 mm ammunition round. The round features controlled guidance and camera front end, which can be fired as fin stabilized with no appreciable spin, from an M320 grenade launcher. The round has a launching sleeve with an oversized propellant cup, to essentially double or triple conventional range, with sharp accuracy provided by the guidance system.

40 mm extended range high performance projectile with rocket and guidance navigation control capability and decoupling device

Shown is a family of low spin and essentially no spin, full in-bore 40 mm projectiles which can be fired from a standard M203 or M320 grenade gun launcher. The projectiles have extended range through over 1000 meters and also have the capability for adding on guidance-navigation and control features/components for great accuracy. Increased accuracy is also provided by another, rear fin type projectile embodiment. The projectiles can be lengthened to accommodate more lethal fragments, and increased amount of explosive and energetic. At the same time, there is provided a training round of analogous performance for all these tactical projectiles.

Training (reuseable), and tactical (guidance adaptable), 40 mm projectile

A cartridge launched in an M203/M320 gun launcher device, which cartridge has fins of 1-5 inches in length to insure flight stability without spinning the cartridge. The non spin makes the cartridge capable of having a guidance navigation and control, canard actuating system added between the body and nose. The guidance navigation and control, canard actuating system features now make the cartridge suitable for successfully attacking stationary and moving targets not heretofore possible.

Enhanced stability extended range (guidance adaptable) 40 mm projectile

A non-spinning 40 mm ammunition round for firing in an M320 grenade launcher. The round includes a cylindrical shaped gun sleeve cartridge case, which covers the standard rifling inside the M320, and thus presents a smooth bore surface to the fired ammunition. Because the ammunition is not launched in a spinning mode, it may now comprise those guidance and camera components as may be desired which components would not have been possible to employ on a round that is spinning.

40 mm gun sleeve cartridge case for M320 grenade launcher ammunition

A 40 mm ammunition projectile for firing without significant spin in an M203 or an M320 grenade launcher. The ammunition includes a projectile body having hollow inner cavity therein for an explosive warhead; a projectile fin assembly; a projectile nose element having a conically shaped front area thereon; a decoupled projectile sabot in two or more joining sabot petals enclosing the body; a base cartridge case having vent holes, a bowl area for placement of a copper closure cup containing propellant therein, and a closure plug for threading into the rear of said cartridge case. The projectile fin assembly may provide a canted angle on each fin blade to (relatively very slowly) spin up the round at less than 30 Hz. Projectiles with body length less than five inches may be launched in an M203 grenade launcher while projectiles with body length up to eight inches may be launched in an M320 grenade launcher.

40 mm low drag extended range projectile

A fuze explosive train device for detonating a munition that uses a stab firing pin within a pressure cartridge, with the stab firing pin located between a gas generator and a stab detonator. The firing pin is capable of transferring an energy from the gas generator into the stab detonator in a manner that initiates the stab detonator to a high order explosive reaction. A method of initiating a stab detonator using a stab firing pin also is disclosed.
