The proficiency bonus is definitely closer to 20% than 10%. Akitsushima with double chevron seiran, T4 sonar and T3 depth charge hit 119 damage against the 19hp (7 armour) sub in parallel engagement.

Akitsushima's attack power before modifiers = (2*sqrt(0) + 1.5*26 + 8)*1.15 = 54.05

54.05*1.3 (line abreast modifier) * 1.5 (crit) * Proficiency bonus - 7* 0.7 - 0.6 * 0 (assuming lowest armour roll) = 119 damage

Using Excel's goal seek tool, proficiency bonus is at least 17.55%. 119 damage lies within the damage range if the aircraft proficiency bonus is 20%.

I actually can't compare expected damage because I don't know the critical hit rates. It'll be much appreciated if someone has exact values on how aircraft proficiency affects critical hit rates.
