She cant.

Isuzu will perform OASW no matter what the equipment is, and has her ASW stat super high (94 at 99) so even if she didnt have this "gimmick", making her OASW at high levels with one slot would be possbile, using T4 sonar you need 88 ASW to reach 100. A good example is Asashio K2D, who has 89 total ASW and is used for 1-slot OASW.

On the other hand, someone with 99lvl Tatsuta claimed her ASW to be 82, which is not enought to reach 100 with 1 item. Even the newest british 5-star Sonar gives 15ASW, not 18ASW. So... only 2-slot OASW, unless you marry her.
