The Vision
Shipmate isn't just another submarine game - it's a living museum that transforms historical research into interactive experience. Our mission is to sustain and preserve the authentic operational procedures, technical systems, and human stories of these remarkable vessels that helped change the course of naval warfare.
The Balao-class submarines, commissioned from 1943-1945, represented the pinnacle of American submarine technology during WWII. With 120 boats built, they were instrumental in the Pacific Theater, sinking hundreds of enemy vessels and rescuing downed aviators. USS Tang alone sank 33 ships totaling 116,454 tons, while USS Archerfish claimed the largest warship ever sunk by a submarine - the 59,000-ton carrier Shinano.
What Makes Shipmate Special
Historical Authenticity: Every system, procedure, and component is researched from original naval documentation, survivor accounts, and museum archives. From the six-valve manifolds to emergency diving procedures, we're recreating the real submarine experience.
Living Replica Technology: Unlike traditional simulators that focus on combat action, Shipmate emphasizes the authentic operational reality - managing crew morale, executing complex diving procedures, operating historical equipment exactly as the original crews did.
Educational Heritage: Each simulation session becomes a bridge connecting modern users with the extraordinary men who served aboard these vessels, preserving their procedures and experiences for future generations.
Development Goals
- Technical Precision: Implementing historically accurate control systems, including authentic torpedo data computers, periscope operations, and ballast management
- Crew Simulation: Individual crew members with realistic personalities, skills, and stress responses based on actual service records
- Procedural Accuracy: Every diving procedure, emergency protocol, and operational checklist derived from original naval manuals
- Educational Value: Interactive training modules teaching actual WWII submarine tactics and technology
Why Your Support Matters
Historical simulation requires extensive research, consultation with naval historians, and access to rare technical documentation. Your patronage directly funds:
- Archival Research: Acquiring original technical manuals, crew interviews, and operational reports
- Expert Consultation: Working with submarine veterans and naval historians for accuracy verification
- Technical Development: Implementing complex systems that honor the engineering excellence of these vessels
- Educational Outreach: Creating content that preserves submarine history for future generations
This project represents more than entertainment - it's active historical preservation through cutting-edge simulation technology. Every detail we recreate helps ensure that the incredible legacy of Balao-class submarines and their crews continues to inspire and educate.
Join us in bringing these legendary vessels back to life, one authentic system at a time. Together, we're not just building a simulator - we're preserving naval history.
Support levels include early access to development builds, historical research materials, behind-the-scenes documentation, and direct input on historical accuracy priorities. join to discord: https://discord.gg/3h2VBvKnD2
