Ok i have made some further tests and the result are that in Naval Search and ASW mission i could never have an hit with aircraft in normal range with weapon filters against a submarine or ship. I could get with extended range.
So i changed the tactic and tried with Naval Attack mission but with 40% ASW - this way i could get hits in submarines in normal range. of note that 40% aircraft in ASW employ ASW weapon load not the Naval Attack weapon load despite being in Naval Attack mission.
An unfortunate situation is if i put the Naval Attack mission with say 40% ASW and 60% rest there are still naval attack "leaks" some squadron still make naval attacks despite the 100% quota defined for other proposes. The same issue occurs with Naval Search.
I am of the observation that you are not understanding how the ASW and/or Naval Search missions work.
Neither ASW nor NavSearch mode will ever utilize the Normal Range (Default) Weapons load. Both missions will always use the Extended Range (Reduced) Weapons load. Always. Always. Always. No matter what range you set them at or if they are using drop tanks.
Nav Search uses
Extended Range (Reduced) Weapons load (100kgGPBomb x4) and patrols out to whatever distance you set (22 hexes Max for this aircraft).
ASW uses
Extended Range (Reduced) Weapons load (100kgGPBomb x4) and patrols out to 1/2 whatever distance you set (11 hexes Max for this aircraft).
