Hostile Skies Companion Tier List

Companions (sometimes called pets) ride along on your sorties and provide passive bonuses or active abilities. This tier list ranks every copilot by utility, then recommends the plane each one pairs best with.

S tier

Companion	Role	Best plane
Radar Officer	Spotting	All bombers
Engineer	Repairs	Multi-role
Gunner	Tail defence	Bombers
Mechanic	Field repairs	Multi-role

A tier

Companion	Role	Best plane
Navigator	Boost	Long sorties
Spotter	Spotting	Multi-role
Mechanic Jr.	Repairs	Starter props

B tier

Bombardier	Bombing	Heavy bombers
Observer	Spotting	Any

C tier

Mascot	Cosmetic	Any

How to use this list

• If you main bombers, prioritize the Radar Officer and Gunner.
• If you main dogfighters, the Engineer keeps you alive longer in close fights.
• If you main multi-roles, the Engineer and Spotter combo covers most sorties.

When this list changes

Companion balance shifts rarely. The current list is accurate for v3.5 “Skyline”. The new Mechanic is a strong S-tier pick for multi-role pilots.

How to unlock companions

Companions drop from events and the in-game shop. Save credits from the How to earn gold fast guide to unlock the S-tier picks.

Why the Engineer is S-tier

The Engineer repairs the plane mid-sorta, effectively adding 30% more HP. That makes every fight winnable in a long engagement.

How companion tiers change

Companion balance rarely shifts, but it does shift. The new Mechanic is an example of a recent S-tier pick for multi-role pilots. After each major patch, re-read this page to see if the tier list has been updated.

Pair the companion with the right plane

The companion you pick matters less than the plane you fly. A S-tier companion on a C-tier plane still loses to a B-tier companion on an S-tier plane. Pair the Plane tier list with the companion picks above for the strongest combinations.
