ePropelled, a leader in intelligent propulsion systems, today announced a major expansion of its Sparrow line of high-efficiency brushless motors, introducing three advanced models engineered for mission-critical defense applications.

As modern warfare increasingly relies on uncrewed systems, propulsion technology has become a decisive enabler for endurance, stealth, and payload flexibility The APM 1404, APM 2207.5, and APM 3115 add new levels of power density, reliability, and environmental robustness to the Sparrow family, enabling defense customers to design more capable unmanned aerial systems.

Built for Mission-Critical Defense Applications

The growing demand for lightweight, high-efficiency propulsion in defense platforms, especially for small UAVs, loitering munitions, ISR platforms, and autonomous systems, has accelerated the need for compact, ruggedized motors with uncompromising performance.

• The expanded Sparrow line addresses the growing demand for propulsion solutions that combine lightweight design, high efficiency, and environmental resilience. Key advantages include:
• High efficiency for longer mission endurance
• Optimized power-to-weight ratios for small and mid-sized platforms
• Ruggedized construction for harsh operating environments
• Low acoustic signatures for stealth-oriented missions
• Industry-leading reliability for mission-critical deployments

Introducing the New Sparrow Models

• APM 1404 – Ultra-Light Micro Propulsion

Designed for extremely compact platforms, the APM 1404 delivers exceptional thrust and efficiency at minimal weight, making it ideal for micro-UAVs and short-range ISR drones requiring minimal weight and maximum efficiency.

• APM 2207.5 – High-Output Mini-Class Performance

Offering a balance of power and compact form factor, the APM 2207.5 provides enhanced torque and thermal performance suited for small tactical UAVs, vertical-lift micro-systems, and electric tactical subsystems.

• APM 3115 – High-Power Tactical-Grade Motor

Engineered for demanding mission profiles, the APM 3115 delivers robust propulsion performance, supporting loitering munitions, medium-range ISR drones, and hybrid tactical platforms.

A Strengthened Commitment to Defense Innovation

“As defense requirements evolve, propulsion technology must evolve with them,” said Nick Grewal, CEO at ePropelled. “By expanding our Sparrow line, we’re providing system integrators and defense innovators with industry standard motors and propulsion systems that are smaller, more efficient, more powerful, and more reliable than ever before.”

ePropelled continues to partner with leading defense organizations worldwide to deliver propulsion and power systems that enhance the capabilities of next-generation unmanned and autonomous platforms.
