Executive summary
Ballistic Internet of Things (Ballistic IoT) is an emerging defense technology concept that uses projectiles to deploy sensors, communications equipment, and potentially autonomous computing capabilities into environments that conventional networks cannot easily reach.
The underlying idea is to transform a projectile from something that simply delivers a physical effect into a means of delivering distributed intelligence or network connectivity.
The most directly relevant intellectual property is held by Booz Allen Hamilton. Its U.S. Patent 10,859,355, granted December 8, 2020, describes projectile-based devices containing sensors, processors, antennas, and wireless networking capabilities.
Key research findings
- Documented technology: Booz Allen Hamilton has a granted U.S. patent explicitly covering Ballistic IoT. Related U.S. military programs have demonstrated deployable microsensors, distributed sensing, and tactical networking.
- Applications: Potential uses include remotely deployed reconnaissance, environmental sensing, communications relays, battlefield monitoring, and intelligence collection.
- Field testing: The Army has documented field experiments involving deployable sensors and networked battlefield technologies. These should not automatically be treated as demonstrations of Booz Allen’s patented ballistic system.
- Combat deployment: Public records support the operational use of several related classes of connected battlefield technology. They do not, on their own, establish that projectile-delivered Ballistic IoT networks have been deployed in U.S. combat operations.
- Principal distinction: A working sensor, a patented ballistic delivery system, a military field demonstration, and a combat-proven capability are four different levels of evidence.
The research therefore needs to distinguish Ballistic IoT in the narrow, projectile-deployed sense from the much broader Internet of Battlefield Things (IoBT). IoBT encompasses connected soldiers, sensors, unmanned systems, vehicles, weapons, and command-and-control networks. The U.S. Army has operated a formal IoBT research program since September 2017.
1. Technology and application categories
Ballistic IoT combines three capabilities: remote physical deployment, distributed sensing, and communication between devices. Not every application needs all three.
| Application | Operational purpose | Evidence maturity |
|---|---|---|
| Projectile-deployed sensor nodes | Place sensors in inaccessible or dangerous locations | Patented concept |
| Tactical reconnaissance | Capture imagery or observations beyond visual line of sight | Demonstrated in related systems |
| Wireless communications relays | Extend or establish tactical networks | Field-tested through related systems |
| Distributed environmental sensing | Detect chemical, biological, radiological, or environmental hazards | Multiple Army field demonstrations |
| Acoustic threat detection | Detect gunfire and estimate source location | Combat-deployed adjacent technology |
| Electronic warfare sensing | Collect or analyze electromagnetic signals | Research and experimentation |
| Precision munition telemetry | Measure projectile performance during flight | Established test-and-evaluation capability |
| Networked autonomous systems | Coordinate drones, sensors, and battlefield decision systems | Field-tested; related systems operational |
Sources include the Booz Allen patent, DEVCOM’s deployable microsensor program, Army telemetry research, and combat reporting on acoustic detection.
How a Ballistic IoT network would function
Conceptual architecture, not a depiction of a confirmed deployed system. C2 means command and control.
The distinguishing feature is where and how sensing or connectivity is delivered. A conventional wireless sensor network requires someone or something to position nodes. Ballistic delivery could position them remotely without sending personnel into the area.
There are, however, substantial engineering challenges:
- Launch acceleration and impact can damage miniature electronics.
- Small projectiles have severe constraints on battery capacity, antenna performance, and payload size.
- Radio communication can become unreliable because of terrain, interference, jamming, or damaged antennas.
- Distributed devices introduce cyber, identification, and electromagnetic-signature risks.
- Network resilience depends on power, coverage, secure communications, and the ability to tolerate lost nodes.
These are particularly important when evaluating the difference between a plausible patented design and a dependable military capability.
2. Companies and research organizations developing relevant technology
The following organizations are not all developing the same type of Ballistic IoT. The distinction between direct projectile-based technology and supporting battlefield IoT infrastructure is important.
1. Booz Allen Hamilton | United States
Direct Ballistic IoT intellectual property
Its patented system proposes projectile-integrated motion sensors, processors, wireless radios, and impact-protection materials. The patent describes multiple projectile forms and potential networked sensing applications.
Evidence: Granted U.S. Patent 10,859,355. Publicly verified military fielding of this specific system has not been established.
2. DefendTex | Australia
Ballistically launchable autonomous platform
Its Drone40 is a miniature unmanned aircraft that can be hand-launched or fired from compatible grenade launchers. It supports modular payloads, including reconnaissance sensors and electronic warfare equipment.
Evidence: U.S. Marine Corps evaluation at Camp Lejeune in July 2021, supported by official military photographs. Published U.S. testing does not establish U.S. combat deployment.
3. ST Engineering | Singapore
Projectile-delivered reconnaissance
Its 40mm SPARCS product is designed to provide aerial imagery and situational awareness using a grenade-launcher-compatible surveillance device.
Evidence: Manufacturer product documentation and published descriptions. No independently verified U.S. operational deployment identified.
4. Design West Technologies | United States
Distributed microsensor delivery
Design West developed the DropPuck delivery system, used with Army researchers to distribute small sensors that communicate over a wireless mesh.
Evidence: Army-documented demonstrations at Aberdeen Proving Ground and the Army Expeditionary Warrior Experiment in 2023. Drone delivery, not ballistic delivery.
5. RTX / Raytheon BBN | United States
Combat-proven ballistic threat sensing
Raytheon BBN developed Boomerang, an acoustic system that detects incoming small-arms fire and estimates the shooter’s location.
Evidence: Documented installation and use in Iraq and Afghanistan. It detects ballistic events but does not deploy sensors through projectiles.
6. Teledyne FLIR | United States
Sensor deployment platform
Army engineers integrated the Skyraider drone with microsensor dispensers. It provides a delivery platform for distributed sensors rather than developing Ballistic IoT itself.
Evidence: Army DEVCOM field experimentation.
7. AeroVironment | United States
Networked tactical unmanned munitions
The Switchblade family integrates remotely operated sensing, video communications, and precision effects. It represents an operationally mature adjacent technology, not a distributed ballistic sensor-node system.
Evidence: The Army documents initial combat support fielding in Afghanistan beginning August 2012.
The Army Research Laboratory and DEVCOM Chemical Biological Center are also particularly important public-sector developers. Their programs provide some of the strongest primary-source evidence for projectile-compatible reconnaissance devices and deployable battlefield sensor networks.
3. Verified field tests and military experiments
This is the most useful evidence for establishing technological maturity. The following events have identifiable dates, locations, participating organizations, and published reporting.
| Date and program | Location | What was demonstrated | Assessment |
|---|---|---|---|
| 2020: Army GLUAS research | Aberdeen Proving Ground, Maryland | Army researchers described a grenade-launcher-compatible surveillance drone design, including two proposed configurations. | Research concept; published source does not verify a successful launch trial. |
| July 2021: Drone40, Operation 40 Switch | Camp Lejeune, North Carolina | U.S. Marines evaluated and recovered DefendTex Drone40 aircraft. Official photographs and video document the exercise. | Verified military evaluation. Public imagery primarily documents hand-launched use, not successful ballistic launch. |
| Early 2023: DropPuck / microsensors | Aberdeen Proving Ground, Maryland | DEVCOM and Design West demonstrated remotely deployed sensors communicating across a mesh network. | Verified field demonstration. |
| March 2023: Army Expeditionary Warrior Experiment | Fort Leonard Wood, Missouri | Soldiers and researchers evaluated distributed microsensor technology and its operational suitability. | Verified field experimentation. |
| April–July 2024: Rio Robotico and Tenacious Dragon 2 | West Texas and Camp Bullis, Texas | Army researchers assessed microsensor distribution, wireless communications, detection, and integrated early warning. | Verified field experimentation, with reported functional results. |
| September 2024: Vanguard 24 | Fort Huachuca, Arizona, with distributed test locations | The Army experimented with drone-delivered sensors, multisource intelligence, and sensor-to-shooter data transmission across geographically separated locations. | Verified military systems experiment; not evidence of combat use. |
| March 2025: Project Convergence Capstone 5 | Fort Irwin, California | The Army’s DIMES microsensor system participated in experimentation supporting data-driven decisions and maneuver. | Verified field demonstration. |
| April 2026: Army FUZE TMI | Fort Carson, Colorado | Tested drone-to-ground communications using 5G Sidelink and tactical mesh networking, along with acoustic-sensor data transport. | Verified communications and sensing experiment. |
Two particularly important cases
Army DIMES: Distributed sensor networks
Strongest evidence for distributed sensor deployment
DIMES, or Deployable Integrated Microsensor Evaluation System, comprises small sensor packages, communications electronics, and power sources. The Army has tested placement from unmanned platforms and the networking required to communicate detection data back to operators.
Importantly, the Army’s 2025 account identifies continued work on sensor selection, detection confidence, mesh networking, and deployment mechanisms. Those remaining tasks show that successful demonstrations do not mean the complete system has finished operational qualification.
Marine Corps Drone40: Projectile-compatible delivery
Strongest U.S. military evidence for a ballistic-launch-compatible sensor platform
DefendTex’s Drone40 can carry intelligence payloads and has a grenade-launcher-compatible design. The July 2021 Marine Corps experiment is directly documented through Defense Visual Information Distribution Service photographs and video.
The critical qualification is that an aircraft being compatible with a grenade launcher does not prove that its deployment by grenade launcher was successfully demonstrated in this particular exercise.
The two efforts are complementary. DIMES has stronger published evidence of distributed sensor-network experimentation. Drone40 has stronger evidence of a projectile-compatible airborne form factor. Public reporting does not establish that the two capabilities have been combined into a combat-qualified U.S. Ballistic IoT system.
4. Evidence of actual use in U.S. combat operations
For operational validation, the crucial question is whether a technology was deployed in an active theater, actually used by military forces, and documented as participating in operations.
The following systems provide increasingly mature examples of networked battlefield technologies, although none independently establishes combat deployment of Booz Allen’s projectile-based Ballistic IoT design.
| Theater / operation | Technology and documented use | Evidence assessment |
|---|---|---|
| Iraq, Operation Iraqi Freedom (2003 onward) | Blue Force Tracking provided near-real-time friendly-force positions and tactical communications across combat formations. | Combat-proven networked battlefield capability. Official Army history records its use during the initial Iraq invasion. |
| Iraq, Operation Iraqi Freedom (2004–2011) | Raytheon BBN’s Boomerang systems detected incoming gunfire and helped troops identify firing directions. The Army documented installations in Basra in 2009. | Verified combat-theater fielding. No ballistic sensor delivery is involved. |
| Afghanistan, Operation Enduring Freedom (2012 onward) | Switchblade/LMAMS combined onboard imaging, wireless video, remote operation, and precision engagement. | Documented combat employment. The Army reports fielding beginning August 2012, operational engagements, and feedback from soldiers using the system. |
| Iraq, operations supporting the battle for Mosul (2016–2017) | U.S. Army units used the mobile WIN-T Increment 2 tactical network to maintain communications and situational awareness while supporting Iraqi forces. | Verified operational-theater use. Demonstrates mobile battlefield networking, not projectile-deployed sensors. |
| U.S. European Command (2023 onward) | Booz Allen reports deployment of its Modular Detachment Kit battle-management technology across the European theater. | Vendor-reported operational deployment. Not equivalent to independently confirmed combat use, and not Ballistic IoT. |
| Middle East, U.S. CENTCOM (2025–2026) | CENTCOM established Task Force Scorpion Strike using autonomous-capable LUCAS aircraft, subsequently reporting one-way drone employment during Operation Epic Fury in 2026. | Officially reported operational and combat use of adjacent autonomous technology. No evidence of projectile-delivered distributed sensor nodes. |
What these operations actually establish
The Iraq and Afghanistan records are particularly valuable because they document three capabilities relevant to Ballistic IoT:
Distributed battlefield awareness. Blue Force Tracking demonstrated that geographically separated combat units could exchange position and operational information through a networked architecture.
Sensor-driven detection in combat. Boomerang demonstrated that electronic sensing and local computation could provide tactical information during deployed operations.
Networked sensing linked to weapon effects. Switchblade demonstrated that an expendable remotely operated platform could transmit imagery and support engagements in an actual conflict.
These are important technical precedents. They establish that components of the broader Ballistic IoT concept have already served operational purposes.
They do not demonstrate that U.S. forces have used rifle-fired or grenade-fired network nodes to establish distributed IoT coverage in combat.
That narrower claim remains unverified in the public evidence reviewed.
5. Evidence maturity and remaining gaps
The available research supports the following assessment.
| Technology | Documented maturity | Evidence of U.S. combat use |
|---|---|---|
| Booz Allen Ballistic IoT | Granted patent | Not publicly established |
| Army GLUAS | Published research design | Not publicly established |
| DefendTex Drone40 | Military evaluation | Not verified for U.S. forces |
| ST Engineering SPARCS | Documented product | Not verified for U.S. forces |
| Army DIMES / DropPuck | Multiple field demonstrations | Not publicly established |
| Raytheon BBN Boomerang | Operationally fielded | Yes, Iraq and Afghanistan |
| AeroVironment Switchblade | Combat-qualified and operational | Yes, Afghanistan |
| Blue Force Tracking | Long-established operational system | Yes, Iraq and Afghanistan |
The largest unresolved questions for Ballistic IoT are whether projectile-integrated communications survive repeated representative launches, whether deployed nodes create dependable networks under contested conditions, and whether those capabilities improve outcomes enough to justify their costs and operational complexity.
A note on verification: An official Army account establishes that a military experiment occurred and reports what participants observed. It is not necessarily an independent engineering evaluation. For stronger performance claims, the ideal evidence would be a published test report containing methods, performance measurements, failure rates, and operational limitations.

For a technical historical predecessor, the 2001 SPIE paper Grenade-Launched Imaging Projectile System (GLIMPS) is particularly relevant. Its abstract describes a system for delivering a sensor package using a grenade launcher, including launch-shock mitigation and video transmission. It demonstrates that projectile-delivered sensing predates the Ballistic IoT terminology, although the abstract alone does not establish operational fielding.
7. Overall assessment
Three conclusions are defensible.
First, Ballistic IoT is technically grounded, not merely speculative. Projectile instrumentation, miniature computing, wireless sensing, and distributed tactical networking all have documented histories. There is also explicit intellectual property addressing their integration.
Second, the U.S. military has demonstrated several of the necessary component technologies, including remotely distributed sensor networks, projectile-compatible reconnaissance platforms, and communications that operate among geographically dispersed battlefield devices.
Third, public evidence does not yet establish that fully integrated, projectile-delivered Ballistic IoT sensor networks have been used in modern U.S. combat operations. The demonstrated combat capabilities are closely related technologies rather than proof of that specific architecture.
The most important development to follow is the intersection of Booz Allen’s projectile-based networking concepts with the Army’s DIMES distributed microsensors and ongoing tactical edge communications research.
That intersection represents a credible direction for future systems. It should, however, be characterized as a potential technology convergence rather than a confirmed integration program.
Research conclusion: Ballistic IoT has a defensible technical foundation and compelling adjacent field evidence, but its maturity as a dedicated U.S. combat capability remains unverified in publicly available sources as of October 2026.
