What's New in 40mm from Defense Technology

Written by Eugene Nielsen

Impact munitions took a quantum leap forward with the release of the Defense TechnologyÒ 40mm eXact iMpactÔ sponge round in 1999. The 40mm eXact iMpact sponge was a revolutionary step forward from the bean bag, single baton and multiple projectile rounds then in use.

The 40mm eXact iMpact originates from the XM1006 developed by the U.S. Army Research Laboratory. Defense Technology licensed both the production and distribution of the munitions to law enforcement from the U.S. Department of Defense. The arrival of the 40mm eXact iMpact initiated the transition from 37mm smoothbore tear gas guns to 40mm rifled launchers in law enforcement.

The eXact iMpact utilizes a lightweight, high-speed projectile that incorporated a plastic body and a foam (sponge) nose. The projectile is spin-stabilized via an incorporated rifling band and the 40mm launcher’s rifled barrel. Smokeless powder is employed as the propellant for consistent velocities and unobscured vision.

The eXact iMpact is a point-of-aim, point-of-impact direct fire round designed for engagement distances from 5 feet to 100 (+) feet. The munition has been rigorously tested to ensure that its impact energy and accuracy remain consistent across all operational ranges.

 

Tests for Effectiveness

While there isn’t any existing single, definitive test protocol for less-lethal munitions, Defense Technology utilizes several testing methods to assess risk of injury potential due to blunt impact or penetration. These include a clay penetration test adapted for non-lethal impact munitions from the NIJ0101.03 Standard test for body armor; blunt impact assessment using the 3-Rib Chest Structure (3-RCS) biomechanical surrogate developed by Wayne State University; and penetration assessment using ballistic gelatin. Defense Technology’s product development incorporates extensive human effects testing using all available test methods to ensure the safety and less-lethal performance of its products. 

The line of 40mm impact munitions include the eXact iMpact Extended Range Round; Direct ImpactÒ Extended Range Round; Aerial Warning-Signaling Munitions; 6530 eXact iMpact/Direct Impact 250-Shot Training Kit; 40mm 1327 Single Launcher with Triple Latch; and the Launcher Carry System.

 

40mm eXact iMpact Extended Range Round

The Defense Technology 40mm eXact iMpact Extended Range Round (Part No. 6325LE) evolved from the design of the eXact iMpact. It was designed for use in situations where greater accuracy and deliverable energy is desired for the incapacitation of an aggressive, non-compliant subject at greater distances. It is intended to be used in applications that exceed the performance capability of the standard eXact iMpact round.  These include elevated positions in corrections facilities, adding safe stand-off to arrest teams with almost sniper precision of less-lethal options. 

The eXact iMpact Extended Range Round has a minimum safe range of 10 yards and an optimal energy range of 10–70 yards. It delivers almost double the energy at 70 yards compared to the standard eXact iMpact Round. As with all Defense Technology less-lethal impact rounds, the 40mm eXact iMpact Extended Range Round has undergone extensive testing to ensure that the round is less-lethal when fired within the optimal energy range and at the large muscle groups of the buttocks, thigh, and knees.

 

40mm Direct Impact Extended Range Rounds

The Defense Technology 40mm Direct Impact Extended Range Round evolved from the design of the Defense Technology Direct Impact Round. It has a lightweight, high-speed projectile that consists of a plastic body and a frangible foam nose that contains a powder payload. As with the eXact iMpact Rounds, the Direct Impact Extended Range Round is spin-stabilized via the incorporated rifling band and the 40mm launcher’s rifled barrel. These rounds also utilize smokeless powder.

The round is available in several different powder payload options, including inert (Part No. 6323LE), marking (Part No. 6326LE), OC (Part No. 6320LE) or CS powder (Part No. 6322LE). The crushable foam nose is designed to dissipate energy upon impact while releasing the powder payload in a cloud approximately 2 yards in diameter.

As with the eXact iMpact Extended Range Round, the Direct Impact Extended Range Rounds are designed for use in situations where greater accuracy and delivered energy is desired for the incapacitation of an aggressive, non-compliant subject at greater distances.  The Direct Impact Extended Range Rounds also have a minimum safe range of 10 yards and an optimal energy range of 10–70 yards.

The eXact iMpact Extended Range Rounds and the Direct Impact Extended Range Rounds are capable of outstanding accuracy. During our evaluation, the rounds consistently grouped within 6 inches at 50 yards employing the Defense Technology Model 1327 40mm Single Launcher.  

 

40mm 250-Shot Training Kit

The Defense Technology 40mm eXact iMpact/Direct Impact 250-Shot Training Kit provides a low-cost way to train through the use of reusable components that accurately simulate the trajectory and performance of the operational rounds. The eXact iMpact / Direct Impact 250-Shot Training Kit contains 25 yellow plastic projectiles, 25 blue anodized aluminum shell bases with set screws, and 250 propellant cartridges.

Each projectile and shell base is intended to be used 10 times, and then discarded. These rounds are designated for training only and if they are fired beyond 10 times, performance and accuracy may be compromised. 

 

40mm Aerial Warning-Signaling Munitions

The 40mm Aerial Warning-Signaling Munitions series are designed to produce 170 dB of sound output and 5 million candelas of light that are noticeable in day or night conditions. Each munition employs a time fuze and is manufactured to deflagrate at a set distance, either 100,  200 or 300 yards from the point of firing depending on the specific round.

When fired at a 15-degree elevation, the munitions will deflagrate 20 feet over the target at the specified range, which is clearly marked on each round. There is also a tactile reference on the nose of the round that serves as a low-light indicator of the designated distance for that particular round.

The Aerial Warning-Signaling Munitions are designed to give the operator the ability to engage people, vehicles or vessels from a safe stand-off position. Some of the applications for the Aerial Warning-Signaling Munitions include directing munitions toward approaching vehicles at checkpoints as a less-lethal way to stop potential threats; and directing the munitions over the heads of crowds for warning or direction.

           

40mm Single-Shot Launcher

The Defense Technology Model 1327 40mm Single-Shot Launcher is an upgraded version of the 1325 Single-Shot Launcher that incorporates several new features to improve performance and functionality with the extended range munitions.

Designed to fire all Defense Technology 37/40mm and 40mm rounds, the 40mm Single-Shot Launcher features an aluminum rifled barrel, which comes equipped with a top and bottom 12-inch Picatinny Rail, Front and Rear Pop-Up Adjustable Sights, Rail-Mounted Adjustable Fore-Grip, Folding Stock with Adjustable Cheek Piece and Grip, and a One-Point Sling.

The 40mm Single Launcher will support the use of additional optics, and accessories with the Picatinny Rails. The upgrade provides the operator with the most accurate platform to be used with the most accurate munitions. To that end, the adjustable cheek piece allows the operator to adjust for proper eye relief and alignment regardless of the optics incorporated. The launcher can be operated in single or double action mode, ensuring optimal control and repeatable accuracy for any situation. The folding stock allows for convenient or covert carrying and storing of the launcher.

Defense Technology offers a 40mm 1325A Upgrade Kit that includes all of the new features, plus the Triple Latch for extended range munitions. In addition to installing the upgraded components at the factory, Defense Technology will inspect and adjust your launcher and reset the warranty for two years as part of the Upgrade Kit.                     

 

Launcher Carry System

Defense Technology offers a customizable, backpack Launcher Carry System specifically designed for mobile field force or tactical teams. The system combines a rugged carry bag constructed of durable 750-denier ballistic weave fabric. This carry bag is equipped with an integral water bladder and features a cushioned, removable cummerbund belt.

The bag has wide padded shoulder straps for comfort and support, as well as a molded, rigid foam frame to help the bag retain its shape and reduce weight overall. The three outward facing sides of the bag are covered with 1-inch modular PALS webbing to attach Accessory Pouch Kit options.

Two Accessory Pouch Kits are available. Accessory Pouch Kit #1 is focused on less-lethal impact munitions and contains six triple munitions pouches, two single grenade pouches, two pouches with capacity for seven munitions, and a gas mask pouch. The Accessory Pouch Kit #2 is designed for chemical agent missions and contains six double grenade pouches, two single grenade pouches, two pouches with capacity for seven munitions each, and a gas mask pouch.
