The only way to unlock new ships in R-Type Tactics I • II Cosmos is through the Research and Development (R&D) menu. This system is your central hub for expanding your fleet, requiring you to spend resources gathered from missions to progress through a vast, branching technology tree. Developing a base unit, like the iconic R-9A Arrowhead, is the first step to unlocking its more powerful and specialized variants.
There are no shortcuts or cheat codes; your fleet's strength is a direct result of your strategic investment in R&D. This guide breaks down the entire process, from managing resources to navigating the human and Bydo tech trees to secure every last ship.
The R&D Engine: Your Path to a Bigger Fleet
Think of the R&D menu as your command center's engineering bay. The core gameplay loop is simple but deep: you complete missions, earn resources, and then spend those resources to unlock new units and equipment. Once a unit is developed, you can produce as many copies as your budget allows for deployment in subsequent missions.
Three primary resources fuel all development:
- Solonium: The most common resource, used for developing and producing early-to-mid-game human technology, particularly standard R-Fighters and their armaments.
- Etherium: A rarer material required for more advanced human technology. You'll need a steady supply for developing powerful late-game ships, advanced Force devices, and specialized warheads.
- Bydogen: An organic, alien material harvested from the Bydo. It is the exclusive resource for developing and producing units in the Bydo technology tree. You will only start accumulating this in significant quantities once you gain access to the Bydo campaign.
The most efficient way to gather these resources is to replay missions you can complete quickly and effectively. Higher ranks (S-Rank) often yield greater rewards, so optimizing your strategy for a specific farming mission is a key part of the grind.
Navigating the Human Technology Tree
The Space Corps' technology tree is a sprawling web of possibilities, starting from humble beginnings and branching into highly specialized machines of war. Your choices here will define your fleet's capabilities. It's generally wise to focus on one or two branches initially rather than spreading your resources too thin.
Early Game Priorities: The Arrowhead Line
Your journey begins with the R-9A Arrowhead. This is the workhorse of your fleet and the prerequisite for almost everything else. Your first few development points should be spent on its immediate upgrades.
- R-9A Arrowhead: The starting point. Focus on developing its associated Standard Force and initial Wave Cannon upgrades.
- R-9B Strider: A slightly more durable variant, offering a solid and inexpensive upgrade path early on.
- R-9C War-Head: An important branch point. Developing this model opens up access to more powerful Force devices and the bomber-focused "Albatross" line of ships.
This initial phase is about building a balanced fleet that can handle the first dozen or so missions while you accumulate a stockpile of Solonium and Etherium.

Mid-Game Branching Paths
Once you've established your core fleet, you'll face significant choices. The tech tree splits into several distinct philosophies of combat. Do you prefer overwhelming firepower, surgical precision, or defensive fortitude?
- The "Shooting Star" Line (R-9D): This path focuses on enhanced Wave Cannons and leads to ships like the R-9D Shooting Star and the R-9DH Grace Note. These are excellent offensive units that can charge their main weapons faster or to higher levels.
- The "Albatross" Bomber Line (RX-10): Starting with the RX-10 Albatross, this branch provides heavy bombers equipped with powerful missiles and bombs. They are slow but essential for cracking heavily fortified enemy positions and capital ships.
- The "Leo" Line (R-9Leo): This unique fighter uses bits that can fire independently, making it a versatile choice for dealing with swarms of smaller enemies. It's a resource-intensive but powerful branch.
Your choice should depend on your playstyle. A fleet heavy on Shooting Star variants will excel at long-range engagements, while an Albatross-focused fleet can deliver devastating alpha strikes.
The Ultimate R-Fighters
At the apex of the human tech tree are legendary fighters that require immense resource investment and the development of numerous prerequisite units. These are your ultimate goals.
- R-9Ø Ragnarok: Often considered one of the most powerful standard R-Fighters, the Ragnarok boasts a devastating Mega Wave Cannon. Unlocking it requires deep progression down the main R-9 line, often needing the R-9D and R-9K series as stepping stones.
- RX-12 Cross the Rubicon: A transformable unit that excels in both fighter and assault roles. Its development path is complex, often requiring technology from both fighter and bomber lines.
- OF-5 Kagu-tsuchi: A unique craft from the OF (Orbital Fighter) series, it uses the flexible OF-Force and offers a different tactical approach. This branch typically requires you to develop support craft and alternative Force devices first.
Reaching these units is a testament to your dedication, as they sit at the very end of long and expensive development chains.
How Mission Progress Gates Your Research
You cannot simply farm the first mission indefinitely and unlock the entire tech tree. R-Type Tactics gates your R&D progress behind story completion. New tiers of research and more advanced ship schematics only become available after you've cleared specific key missions.
For example, the ability to research Tier 3 ships might be locked until you complete Mission 15 or 20 of the human campaign. The game signals this by revealing new, previously shadowed-out options in the R&D menu after a major story beat. This ensures your fleet's power level grows in sync with the campaign's difficulty.
While S-ranking missions or completing optional objectives doesn't typically unlock unique ships directly, it is the single best way to accelerate your progress. The massive resource bonuses from high-ranking clears allow you to fund your R&D projects far more quickly than just scraping by with C-ranks.

Playing as the Enemy: Unlocking the Bydo Fleet
One of the most compelling features of R-Type Tactics is the ability to command the Bydo Empire. This isn't just a cosmetic change; the Bydo have their own distinct campaign, units, and a completely separate technology tree powered by Bydogen.
Accessing the Bydo Campaign
To begin unlocking Bydo units, you must first complete the main human campaign. Upon finishing the final human mission, the game will unlock the Bydo campaign, allowing you to experience the conflict from the other side. From this point on, you can choose which campaign to play and will begin earning the Bydogen necessary for their unique development tree.

The Bydo Development Chart
The Bydo tech tree is a twisted mirror of its human counterpart. It's filled with grotesque, powerful organic weapons that often prioritize brute force and regeneration.
Key Bydo units to aim for include:
- B-1D Bydo System α: The foundational Bydo unit, equivalent to the R-9A. It's the gateway to the entire Bydo arsenal.
- Gauper Series: These are the standard Bydo fighters, evolving into more potent forms with enhanced organic weaponry.
- Dobkeratops: A legendary, massive Bydo creature that functions as a mobile fortress. Unlocking it is one of the ultimate goals of the Bydo campaign, requiring you to reach the deepest parts of their twisted tech tree.
- B-3C Amor-Eater: A heavy assault craft that embodies the Bydo philosophy, designed to tear through enemy armor with powerful close-range attacks.
Mastering the Bydo fleet requires a different mindset. Their units are often slower but more durable, with abilities that can surprise an opponent accustomed to human tactics.
Frequently Asked Questions
Here are quick answers to some of the most common questions about unlocking the fleet in R-Type Tactics I & II Cosmos.
Can I permanently miss unlocking a ship?
No. All ships are available through the R&D tree. You cannot lock yourself out of an unlock. The only requirement is to progress far enough in the story (for both human and Bydo campaigns) and accumulate the necessary resources.
What's the fastest way to farm resources?
Find a mid-to-late-game mission that you can reliably S-Rank in a short amount of time. Missions with high densities of enemy capital ships or resource containers are ideal. Once you find a good candidate, optimize a specific fleet build to clear it as efficiently as possible and repeat it as needed.
Do unlocked ships carry over between the Tactics I and Tactics II campaigns?
Yes, within the Cosmos collection, your unlocked unit roster is persistent. The development you complete in the Tactics I campaign will be available for you to use in the Tactics II campaign, and vice-versa, providing a continuous sense of progression across both titles.
How do I unlock the R-99 Last Dancer?
The R-99 Last Dancer is one of the ultimate secret units. Unlocking it typically requires you to complete both the human and Bydo campaigns. After the final mission of both storylines, this legendary, Bydo-tech-infused R-Fighter will become available for development in the R&D menu. It is extremely expensive, requiring a massive amount of all three resource types, making it the final prize for dedicated fleet commanders.
