DefendTex D40 kamikaze drones

The Drone40 40mm quadrotor drone from DefendTex is not entirely new. It first caught my attention back in 2019 when the “programmable 40mm loitering munition” was displayed at the Special Operations Forces Industry Conference in Tampa. The militaries of other countries have deployed the DefendTex D40 kamikaze drones since then, but it wasn’t until this summer (the summer of 2021) that a US military formation publicly utilized it.

The D40 drone can be utilized both for intelligence gathering and as a directed weapon. Deployment is via hand or launched from 40mm grenade launchers like the M320 GLM. Initial reporting indicates it is not compatible with older M203 series UBGLs, and there have been mentions of a potential 12 bore variant to be used with 12 gauge shotguns.

The DefendTex Drone40 utilizes a quadcopter system of four rotors to maneuver, remaining airborne in a combination of flight and loitering time of up to an hour. The drone cruises at approximately 20m/sec (just shy of 45mph) with an optimum range of 20km (12 miles) or more. DefendTex D40 kamikaze drones

The mixed payload types and the D40’s “Multi-Round Simultaneous Impact” capability will allow both individual deployment and coordinated “swarm” attacks. For instance, DefendTex Drone40s with cameras could be set to watch infiltration routes while others loaded with anti-personnel or anti-armor munitions run racetracks nearby awaiting use.

The test and evaluation process of the D40 took place during a recent exercise called Operation 40 Switch. During that exercise, the DefendTex Drone40 (and other equipment, including AeroVironment’s Switchblade drone) were used and evaluated by elements of 1st Battalion, 2nd Marine Regiment (1/2 Marines) at Camp Lejeune, N.C. 1/2 Marines is the “experimental infantry battalion” for 2d MARDIV. The unit is tasked with, as 2d MARDIV describes it, testing “…new gear, operating concepts, and force structures.”

1/2’s findings, they advise, will help refine infantry battalions Marine Corps-wide. DefendTex D40 kamikaze drones

The D40 is not the only grenade-launched surveillance drone out there. For instance, last year the US Army Research Laboratory announced the development of the Grenade Launched Unmanned Aerial System (GLAUS). The GLAUS came in two versions, one a small paragliding system, the other a helicopter-style drone running on coaxial rotors.

Unlike the DefendTex Drone40, however, the GLAUS was not designed for optional use as a kinetic weapon (though it could certainly put the hurt on somebody if flown into them kamikaze-style). DefendTex D40 kamikaze drones

Another drone being evaluated is the Switchblade. The Switchblade, though small enough to carry in a ruck, is much larger than the vertical-bodied DefendTex Drone40 and utilizes a rear propeller to move and maneuver. The Switchblade is tube-launched (the launcher looks like a small mortar) and can also be used in both ISR and kinetic roles. DefendTex D40 kamikaze drones

The USMC is not the only military or branch evaluation drone technology. In mid-July, the UK’s Royal Marine Commandos utilized a wide variety of unmanned systems during Autonomous Advance Force 4.0, an exercise designed to evaluate how such technology could support commando forces on the battlefield. Among the tasks accomplished during those trials was the successful tactical resupply of ammunition to assaulting formations and the delivery of (simulated) blood to medics on the battlefield.

If field-expedient weapons utilizing civilian/commercial Unmanned Aerial Vehicles (UAVs) achieved such a relatively high level of success, it seems reasonable to expect that the DefendTex Drone40, Switchblade, and other systems like them will be a significant force multiplier when the time comes for those acting in the United States interests to put boot to ass.
