If you are evaluating UAS platforms for a DoD program, university research grant, or government agency, the Group classification system will come up early and often. Understanding it upfront saves significant time in procurement and prevents the common mistake of selecting a platform in the wrong Group for your approval pathway — a mistake that can add months to a program timeline.
The DoD UAS Group System
The Department of Defense categorizes unmanned aircraft systems into five groups based on maximum gross takeoff weight, operating altitude, and airspeed. The groups determine which authority can approve operational use, what training standards apply, what acquisition category your program falls into, and in some cases which contracting vehicle is appropriate.
| Group | Max Gross Takeoff Weight | Operating Altitude | Airspeed |
|---|---|---|---|
| Group 1 | ≤20 lbs (9.1 kg) | <1,200 ft AGL | <100 kts |
| Group 2 | 21–55 lbs (9.5–25 kg) | <3,500 ft AGL | <250 kts |
| Group 3 | <1,320 lbs (600 kg) | <18,000 ft MSL | <250 kts |
| Group 4 | <1,320 lbs (600 kg) | Any altitude | Any airspeed |
| Group 5 | ≥1,320 lbs (600 kg) | Any altitude | Any airspeed |
Most tactical programs, research programs, and government agency programs operate in Groups 1 through 3. Groups 4 and 5 cover large systems like the MQ-1C Grey Eagle and RQ-4 Global Hawk that require Major Defense Acquisition Program (MDAP) structures.
What the Classification Means for Your Program
Approval Authority
The classification determines who can authorize operational use of the platform — a decision that directly affects how quickly your program can move.
Group 1 platforms can typically be approved at the installation level or unit command level. Most DoD organizations can authorize Group 1 use under existing UAS policy without requiring higher-level review. This is why Group 1 platforms have become the primary experimentation tool for innovation cells and rapid fielding programs.
Group 2 platforms require more formal approval processes. Depending on the service and command, Group 2 operational use may require installation airspace coordination, a flight operations review, and command-level sign-off. Still manageable for most programs, but the approval timeline is longer than Group 1.
Group 3 platforms require formal operational approval from an authority above the installation level in most cases, particularly for BVLOS operations. Programs planning to use Group 3 platforms for operational missions — rather than just testing — should build 90–180 days of approval process time into their program schedule.
Training Requirements
Army Regulation 95-23 and equivalent service regulations tie formal training requirements to platform group. This affects both your program timeline and your operating costs.
Group 1 training can often be accomplished organically within a unit. Basic operator qualification, FAA Part 107 certification where required, and platform-specific familiarization can be achieved through a combination of commercial training and on-site instruction. Forge and Flight Academy’s FFF-401 program is designed specifically for this organic standup model.
Group 2 and 3 platforms typically require formal operator qualification programs delivered by qualified instructors. The training investment is larger — but so is the operational capability. Organizations standing up a Group 2 or 3 program should budget for initial operator qualification, recurring proficiency training, and instructor development if they intend to sustain the capability organically.
Procurement Authority and Thresholds
Group classification intersects with acquisition thresholds in ways that affect how quickly you can contract and at what level review is required.
Group 1 platforms frequently fall within the Simplified Acquisition Threshold ($250,000) and sometimes within the Micro-Purchase Threshold ($10,000 for some categories). The Longbow-8 falls within departmental procurement authority for many university programs and defense innovation cells — contact for pricing.
Group 2 platforms like the Aether-10 typically fall within Simplified Acquisition but above the micro-purchase threshold. RFQ process, 3-vendor competition, and contracting officer sign-off are standard — but the timeline is still measured in weeks, not months, when the vendor is SAM-registered and responsive.
Group 3 platforms like the Vanguard-14 and Titan-20 often exceed the Simplified Acquisition Threshold depending on configuration, moving into the full FAR Part 15 competitive acquisition process. Programs with Group 3 requirements should engage a contracting officer early to determine the appropriate vehicle — Other Transaction Authority (OTA), SBIR, or full and open competition all have different timelines.
Group Classification in Practice: Common Mismatches
Several common mismatches between platform Group and program requirements cost programs significant time and budget.
Buying Group 2 for a Group 1 mission. A unit that needs a man-portable training and reconnaissance platform sometimes over-specifies and ends up with a Group 2 system that requires more approval, more training, and more logistics overhead than the mission demands. The Longbow-8 was designed specifically to address this — Group 1 classification with professional-grade capability.
Buying Group 1 for a Group 3 mission. The opposite problem: a research program that genuinely needs 6+ hours of endurance and AI edge computing specifies a Group 1 platform because it’s faster to procure, then discovers it cannot execute the mission profile. The Vanguard-14 fills the Group 3 requirement with a procurement and approval pathway that is still manageable for most programs.
Not accounting for approval time in program schedules. A program that buys a Group 3 platform and then discovers it needs 6 months of command-level operational approval before the first mission flight has effectively wasted half its program year on hardware that cannot be used.
NDAA Section 848 Applies to All Groups
Regardless of Group classification, all DoD UAS procurement is subject to NDAA Section 848 supply chain restrictions. Group classification determines the operational and acquisition pathway — it does not determine compliance. A Group 1 platform assembled from Chinese-manufactured components fails the same compliance test as a Group 3 platform with the same supply chain.
All Forge and Flight platforms — across all four Groups — are manufactured with 100% domestically sourced electronics and come with full BOM documentation and NDAA compliance certificates at purchase.
How Our Platform Lineup Maps to the Groups
| Platform | Group | MTOW | Key Capability |
|---|---|---|---|
| Longbow-8 | Group 1 | 13 kg | Man-portable VTOL, operator training, payload testing |
| Aether-10 | Group 2 | 35–40 kg | 2–5 hr endurance, research and monitoring |
| Vanguard-14 | Group 3 | 40–45 kg | 6–12 hr endurance, AI edge compute, BVLOS |
| Titan-20 | Group 3 | 110 kg | 25 kg payload, 7+ hr, gas hybrid propulsion |
All four platforms are NDAA Section 848 compliant with complete BOM documentation provided at purchase. View full platform specifications → or contact us to discuss which Group is right for your program requirements.
