Baykar’s Kalkan VTOL Launches FPV Drone Mid-Air, Ushering in New Era for Airborne “Motherships”

In a flight test conducted earlier in 2025 and announced on 29 November 2025, Turkish UAV manufacturer Baykar successfully demonstrated the mid-air deployment of a compact FPV drone from its Bayraktar Kalkan VTOL. According to Baykar’s official channels, the Kalkan operated as an airborne “mothership,” launching a small FPV kamikaze drone mid-sortie — a milestone showcasing the growing maturity of layered unmanned aerial systems.

Background: Drone-on-Drone Launch — A Growing Trend

The concept of a larger unmanned aerial vehicle acting as a “carrier” for smaller drones has gained traction globally, especially as militaries explore cost-effective, distributed strike architectures. In this model, a long-endurance UAV carries small loitering munitions or reconnaissance drones and deploys them deep in contested environments — reducing the risk to expensive platforms while maximizing tactical flexibility. The Kalkan VTOL’s recent success underscores this shift.

The Bayraktar Kalkan VTOL had already earned recognition for its hybrid lift-cruise design, combining vertical-takeoff electric motors with a gasoline cruise engine. This allows operation from compact sites — as small as 20 × 20 meters — without runways or catapults. Its medium-tactical endurance, internal payload capacity, and hybrid configuration made it a strong candidate for expanded roles beyond reconnaissance.

Test Details: From Launch to Strike

During the demonstration, the Kalkan — configured with the long-endurance carrier profile — released a compact FPV drone from its cargo. The released drone, identified as a Skydagger FPV kamikaze drone, underwent two distinct release profiles:

• Controlled drop and recovery — where the FPV separated cleanly, stabilized, and completed a safe landing.
• Dive-attack profile — where the FPV transitioned into a direct strike against a fixed ground target.

The dual-mode release demonstrated that Kalkan can function both as a persistent ISR (intelligence, surveillance, reconnaissance) node and as an aerial weapons platform — delivering small munitions or effectors while remaining outside the likely engagement zone of front-line air defenses.

According to specifications, the Kalkan VTOL features a roughly 5-meter wingspan, about 1.5 meters fuselage length, and uses a hybrid propulsion system combining four electric lift motors with a gasoline cruise engine. Its take-off weight falls within the 30–50 kg class, with an internal payload capacity around 3 kg (typically for EO/IR sensors, laser designators, etc.). In previous trials, it demonstrated up to eight hours of flight endurance and a service ceiling above 14,000 ft; line-of-sight data link range varies between roughly 70 and over 100 km depending on antennas.

On the FPV side, Skydagger’s compact attack drones — in their 7-, 10- and 15-inch variants — are reportedly able to carry warheads of roughly 2–5 kg, sustain flight for 12–20 minutes, reach ranges up to 10 km, and travel at speeds of 120–140 km/h.

Strategic Implications: From ISR to Strike, From Motherships to Swarms

Enhanced Tactical Flexibility

By enabling a relatively long-endurance VTOL UAV to act as a deployer for compact FPV drones, the Kalkan test expands mission profiles significantly. Rather than relying solely on satellites, ground launchers, or runway-based drones, militaries can now consider compact, flexible platforms capable of insertion, surveillance, and strike — all within a single sortie. This reduces risk to high-value assets and improves operational flexibility, especially in contested or runway-denied environments.

Layered Unmanned Architectures

The demonstration signals a shift toward layered unmanned systems — combining long-range carriers with expendable, small drones for reconnaissance or strike. As such, forces could employ a mixture of “mothership” UAVs and swarming FPV drones to overwhelm air defenses, saturate targets, or conduct persistent surveillance without exposing costly manned platforms or even larger UCAVs.

Industrial Maturation and Export Potential

For Baykar and its partner drone firms (e.g., Skydagger), the test underlines the progress of Turkish domestic drone industry toward mature, integrated systems. As the company continues refining hybrid-propulsion VTOL carriers and compact FPV strike drones, this capability could appeal to foreign buyers — particularly in regions where runway infrastructure is limited or contested. Further, this reflects Türkiye’s growing role in shaping drone-based doctrines and defense export potential.

What Comes Next

The successful FPV launch from Kalkan is likely just the beginning. As the technology matures, we may see:

• Multi-drone sorties, where a single Kalkan carries and releases several FPV drones, enabling swarm-style attacks or mass surveillance.
• Integration of more capable payloads — perhaps heavier loitering munitions or sensor packages, expanding Kalkan’s role beyond simple ISR to a more active strike and suppression platform.
• Doctrinal adoption by military forces seeking affordable, modular, and flexible force-multipliers — particularly in contested environments or conflicts characterized by anti-access/area denial (A2/AD).
• Export deals, especially with countries lacking large-runway infrastructure or operating in rugged terrain.

Conclusion

The mid-air deployment of an FPV drone from the Bayraktar Kalkan VTOL represents a major milestone in unmanned aerial systems — transitioning the UAV from a pure reconnaissance asset into a versatile airborne carrier capable of delivering payloads deep into contested areas. As layered drone architectures continue to evolve, this test highlights how relatively low-cost, hybrid-propulsion VTOL drones and small strike UAVs can combine to deliver flexible, scalable, and effective capabilities. For militaries and defense planners worldwide, such developments may soon reshape how they think about air-dominance, precision strike, and unmanned operations — making airborne “motherships” a key component of future drone-driven doctrines.
