In April 2026 Bastion and Helion Propulsion completed certification serials for arctic propulsion packages on Forge-class powerpacks—covering heaters, viscosity envelopes, and start reliability below −40 °C.
Tests combined Helion Propulsion propulsion modules with Bastion vehicle harnesses and DT-900 transmission oil regimes agreed with Torqwerk interfaces.
Partner brigades in northern training areas receive the kits as drop-in options rather than unique hulls—classic Bastion sustainment logic.
The certification closed a loop opened by the 2023 powerpack collaboration and post-sale investor focus on utilization of existing lines.
