Engineered to Win
Built to Last

A 30+ year leader in UAV propulsion, Orbital turns proven heavy-fuel innovation into scalable products and long-term service revenue.

Orbital combines proprietary fuel-injection technology (FlexDI™), mission-grade reliability, and an expanding product range (50–350cc engines plus PMS) to meet the sector’s shift toward heavier payloads, longer endurance, and BVLOS operations. Our new three-tier go-to-market - Partnership Programme, Mission-Ready Engines (COTS IPS), and Mission Assurance Support - adds scale while preserving premium differentiation, creating durable customer relationships and recurring through-life revenue.

Orbital's future‍
‍aligned with yours

Proven longevity

Decades of field data and Continuous Product Improvement underpin reliability in harsh theatres.

Defensible tech:

FlexDI™ heavy-fuel efficiency translates into clear TCO advantages for operators.

Scalable model

COTS “Mission-Ready” configurations open broader markets without diluting Tier-1 partnerships.

Recurring economics

Mission assurance, spares, overhaul, and diagnostics drive through-life support revenue.

Positioned for growth

Rising demand for payload, endurance, and BVLOS favours efficient heavy-fuel propulsion - and Orbital’s integrated systems.

Engineered for Every Mission
