[X] Stratagem: Solar Scouring. It's a bit wasteful to use the material on expendable ammunition, but few can deny its effectiveness when in action. The scarcity though makes it hard for any but dedicated artillery units to make use of it so. Unlocks the Solar Scouring stratagem. Requires eight (8) research progress.
[X] Destroyer Hull: Wolf Escort Mk 1. A considerable shift in destroyer design doctrine, this hull utilizes integrated solarium wiring throughout its systems to accelerate system processing. This comes at the cost of being largely incompatible with non-solarium based systems, making it more reliant on itself than anything else. Unlocks the Wolf Escort Mk 1. Requires six (6) research progress.
[X] Plane Airframe: Yata Mk 1. A new efficient fuel composition made using solarium has allowed for this jet to drastically cut down on its internal tanks and focus on adding more armaments. Solar radiation though interferes with electronic systems, making it strongly suggested to refrain from mounting too many until shield-proofing has been developed. Unlocks the Yata Mk 1. Requires six (6) research progress.
