Please, help to identify who could have claimed this MBR?

We were sent in MBR-2 after torpedo boats that attacked ports. They went to Kertch. We found them almost at their port. Still, we bombed them, but after bombs were gone we were intercepted by fighters. Don’t know whether we hit something or not, we had to fight for our lives. Pilots went to 10 m height, we shot at fighters, and they left. Germans did not like low altitudes. We started gaining altitude almost at our shore, I radioed to the ground that we were arriving, when they said that fighter is behind us. Then everything exploded around me, we fell into the water, and when I came to the surface I saw a Me-110, a two- keel plane. Its pilot strafed us and set off.
The event took place on 29 of may 1943 at 6 o'clock in the morning
