Retrofit Route into Mixed Fleets

Forterra’s advantage is distribution, not just autonomy. A customer with Humvees, JLTVs, work trucks, and utility vehicles already in service can buy one retrofit stack and spread it across multiple platforms instead of replacing the fleet. That matters because defense and industrial buyers usually own mixed vehicle bases for years, and budget for upgrades faster than for full vehicle replacement.1 2 3 4

• Forterra has built around a kit model. Its own interview material describes an integrated hardware and software product that can be installed on the factory line and reused across defense and commercial programs, which is what makes mixed fleet deployment practical.2 3
• Overland attacks the same retrofit budget through SPARK and OverDrive, but also sells complete vehicles like ULTRA and IBEX. That gives it tighter control over sensors, compute, and vehicle design, while adding the harder work of manufacturing and supply chain management.1 4
• This pattern shows up in other autonomy markets too. Mining and heavy industry buyers often prefer retrofit systems because they let operators automate trucks and machines already on site, avoid waiting on one OEM roadmap, and expand autonomy fleet by fleet.5 6

The market is likely to split between retrofit autonomy vendors that win by fitting into existing fleets, and full stack vehicle builders that win by delivering better performance on purpose built platforms. Forterra is positioned to grow where buyers want fast automation without replacing vehicles, while Overland can push upward into programs that value tighter hardware and software integration.1 2 4 6
