Place a dedicated healing light aircraft carrier in your mob fleet backline to counteract vanguard attrition across multi-battle campaign runs. Prioritize completing Unicorn's retrofit for standard progression, as her pre-loaded airstrike and regular launch timers supply reliable sustain without dragging down fleet damage. Reserve boss fleet backline slots for dedicated damage dealers, bringing healers into boss fights only during high-attrition campaign stages like Chapters 13 through 15.
Why Mob Fleets Require Dedicated Healers
Mob fleets face five to seven consecutive battles per map, frequently clearing the final encounters under the Out of Ammo debuff. Stray bullets, torpedo spreads, and burn procs continuously wear down escort ships. Without backline recovery, frontline escorts sink before reaching the boss node, causing failed runs and lost S-rank clear ratings. A single backline healer resets vanguard health across each fight.
Boss fleets work under the opposite incentive. Because the encounter features a single priority target and a strict time limit, replacing a battleship or offensive carrier with a healer sacrifices substantial burst damage. Keep dedicated support ships in the mob fleet unless map-specific mechanics—such as Chapter 13 aircraft waves, Chapter 14 concealment, or Chapter 15 attrition—threaten your boss backline.
Support Carrier Comparison
Top healers differ based on launch speed, target priority, and damage trade-offs:
| Ship | Pre-loaded Launches | Primary Target | Key Trade-off |
|---|---|---|---|
| Unicorn (Retrofit) | 1 | Vanguard (every launch) + Main fleet (first launch) | Requires full retrofit investment; maintains standard launch cooldowns and high wave damage. |
| Perseus | 2 | Vanguard and Main fleet (every launch) | Delivers instant opening heals; suffers an 80% launch cooldown penalty on subsequent airstrikes. |
| Volga | 0 | Lowest HP ships across both rows | Needs standard flight preparation time; contributes heavy carrier-tier personal damage. |
| Ryuuhou | 0 | Lowest HP Vanguard escort | Heals scale off her own maximum HP rather than the target's; focuses heavily on single targets. |
| Aquila | 1 (Dive Bomber slot) | Lowest HP ships across both rows | Requires equipping a dive bomber in slot two; yields smaller heals but adds frontline shields. |
Unicorn (Retrofit) vs. Perseus
Unicorn Retrofit serves as the standard sustain carrier for general campaign maps, hard modes, and event farming. Her retrofit tree provides an immediate pre-loaded airstrike, upgraded fighter efficiency, and a skill that restores main fleet health on her first launch while healing the vanguard by 8% of their maximum HP on every launch. Because her follow-up airstrikes operate on standard cooldown intervals, she maintains steady wave-clearing damage in longer encounters.
Perseus excels at rapid early recovery by entering every battle with two pre-loaded airstrikes. Launching both waves back-to-back stabilizes wounded escorts and wipes initial enemy screens. However, her 80% airstrike cooldown penalty severely delays all subsequent launches. Use Perseus for fast mob nodes lasting under 30 seconds, and switch to Unicorn Retrofit when drawn-out battles require sustained healing cycles.
Specialized and Hybrid Options
- Volga: Operates as a full-damage carrier whose airstrikes release targeted healing bursts to the lowest-health ships in the fleet. Deploy Volga when your mob fleet needs backline damage output and suicide boat protection without completely dropping fleet recovery.
- Ryuuhou: Directs multiple heals to the lowest-health escort ship per launch, with the restored amount determined by Ryuuhou's own maximum HP pool. This mechanic makes her effective for power-leveling low-level ships or protecting fragile destroyers with low native HP pools.
- Aquila: Equipping a dive bomber in her second gear slot grants a pre-loaded airstrike, a vanguard damage shield, and targeted healing to the lowest-health ship in each row. Use her when incoming burst damage needs absorption before heals can take effect.
Vanguard Self-Sustain Options
Pairing support carriers with self-sustaining vanguard cruisers reduces backline healing pressure:
- Zombie Cruisers: Ships such as Phoenix, Minneapolis, and Neptune feature emergency survival skills that restore substantial HP once per battle upon dropping below 20% to 30% health. Place them in the leftmost vanguard position to absorb lead damage.
- Pearl's Tears: This auxiliary item restores 10% health to the rest of the fleet when the equipped ship sinks. Save this equipment for emergency high-difficulty stages or exercise PvP setups rather than standard farming fleets.
Gear Tuning for Healer Cooldowns
A support carrier must trigger heals before frontline escorts take fatal damage. Balance equipment to control airstrike timing:
- Equip fast fighters: Mount quick-launch aircraft such as the Messerschmitt Me-155A or F8F Bearcat if your vanguard dies before the first scheduled heal. If the fleet needs supplementary surface damage alongside healing, use balanced fighters like the Vought F4U Corsair (VF-17 Squadron) or Tigercat.
- Install a Homing Beacon: Place the Homing Beacon auxiliary gear on your carrier to reduce airstrike loading time by 4%, ensuring heals trigger ahead of dense enemy torpedo waves.
- Equip a Steam Catapult: Fill the remaining auxiliary slot with a Steam Catapult to raise the carrier's Aviation stat, improving personal damage output and aviation-scaled healing output.

This helped me understand strategy much better.
Good guide for Azur Lane players. The strategy part was useful.
I tried this today and it worked better than my old setup.
The explanation is clear, especially for beginners.
