Fleet Hangars

Fleet hangars in 5Dim

The hangar system allows your ships to transport other ships inside them, multiplying combat power without increasing fleet fuel expenditure and optimizing combat mobility. Understanding how hangar capacity works, which research improves it and what happens when carriers fall in combat is key to designing efficient fleets and avoiding unexpected losses.

The two active states of a ship in 5Dim

Before understanding the hangar, you need to know how each ship can fly

Each ship you send in a fleet can be in one of two states. You will see these values reflected in the shipyard and in the fleet panel.

In fleet
The ship flies freely as part of the fleet, exposed to direct combat. It contributes its attack and defense normally.
In hangar
The ship travels inside another ship with hangar capacity. It also fights, but its survival depends on the ship that transports it.

The same ship can have quantities in both states at the same time. For example: 15 fighters in fleet + 30 fighters in hangar.

What the hangar is and how it works

Large ships can transport smaller ships inside them

The hangar in 5Dim is the ability of a ship to carry other ships inside it during travel and combat. It is not a special ship: it is a feature added to any design through specific components.

There are four types of hangar component, one for each class of ship that can be accommodated:

Fighter Hangar Allows carrying fighters inside the ship. Only corvettes, cruisers, battleships and titans can install it.
Corvette Hangar Allows carrying corvettes. Requires the host ship to be larger (cruiser, battleship, titan).
Cruiser Hangar Allows transporting cruisers inside battleships or titans with the appropriate component.
Battleship Hangar The highest capacity type. Only titans with this component can carry battleships.

The number of ships that fit in the hangar depends on the value of the installed component and is multiplied by hangar research. Standard components (type A–E) offer modest capacities — starting at 1 fighter per slot and rising with class and research — so a ship needs to install several slots to transport an appreciable number. Special class Z components (mass fighter hangar, available only on ships of Cruiser size or larger) offer far superior capacities: a Titan with "Fighter Hangar Z" can transport 256 fighters per installed slot (≈ 379 with research at level 10).

Example fleet with hangars
Titan
Installs 1 Fighter Hangar Z component (base capacity: 256 fighters; ≈ 379 fighters with Hangar Research level 10) → the Titan can carry up to that many fighters inside.
Fighters
300 fighters are placed in hangar of the Titan. They travel inside and fight as if they were in fleet.
Result
In combat, the enemy faces the Titan + 300 fighters. The fleet has more power without occupying more visible fleet "slots".

Hangar capacity is per ship design, not global. If you have 10 Titans with "Fighter Hangar Z" and research level 10 (≈ 380 fighters each), the total capacity of the group is 10 × 380 = 3,800 fighters. Ships in hangar cannot exceed the available carrier capacity.
You can put ships in hangars that in turn have hangars with more ships inside; you can chain as many as you want — build your fleet as you like.

Hangar Research: multiply your capacity

One of the most impactful research for combat fleets

Hangar Research is a technology in the research tree that multiplies the capacity of all hangars on your ships. Each level increases the available capacity, making each carrier able to accommodate more ships for the same cost.

5Dim Hangar Research
Hangar Research Multiplies the hangar capacity of all your ship designs. Cumulative effect level by level.
Multiplier effect (+4% per level) Each level adds 4% capacity: ×1.22 at level 5, ×1.48 at level 10. A ship that carries 256 fighters at base reaches ~379 fighters with research at level 10.

If your playstyle is based on carrier fleets — battleships or titans transporting fighters and corvettes — investing in Hangar Research is as high a priority as Weapons or Armor. A fleet with the same number of ships but with hangar at level 10 expands its hangar capacity by 48% at level 10, and that advantage grows with each additional level.

Hangars in combat: advantages and risks

Ships in hangar fight, but can also be destroyed if their carrier falls

Ships placed in hangar actively participate in combat: they attack, receive damage and can be destroyed by direct fire just like any ship in fleet. This means that putting fighters in a battleship's hangar does not "protect" them from projectile damage.

However, there is a second casualty mechanism exclusive to the hangar: losses due to destroyed hangar. When carriers die, the available hangar capacity is reduced. If the remaining capacity is less than the number of transported ships still alive, some of those ships are also lost.

Hangar loss mechanic
Start
10 Titans with "Fighter Hangar Z" and research level 10 (≈ 380 fighters each = 3,800 total) with 3,000 fighters in hangar.
Combat
6 Titans are destroyed → remaining capacity = 4 × 380 = 1,520 fighters. By direct fire 400 fighters have already died → 2,600 fighters remain alive.
Hangar loss
2,600 live fighters do not fit in 1,520 capacity. The system calculates the proportion and destroys ~1,080 extra fighters due to lack of hangar space.
Final total
4 Titans and ~1,520 surviving fighters.

There are two important exceptions where ships in hangar do not suffer additional losses from this mechanism:

Defender with available planet If you defend an attack, conquest or planet destruction, ships in hangar do NOT receive extra losses due to capacity. The planet acts as an emergency hangar.
Ships with advanced hyper engine Ships with high-level hyper propulsion (hyper speed ≥ 5) ignore additional hangar losses: even if their carrier is destroyed, they are not lost due to lack of capacity, but the fleet's return speed is calculated based on the slowest ship's speed.

When you attack with a fleet carrying ships in hangar, if your carriers are destroyed in combat, the ships they carried may be lost proportionally. Design your carriers with enough armor or protect them with escort groups.
