7 tons of warship.
 

Took a peek into Shizouka harbour, Jan '43. Found 3 big tankers and a Mavis flying boat. Sank 2 of the tankers with torps, and the Mavis with 200 rounds of 20mm. Shoot down a Mavis and get credited with a kill, sink a Mavis get credited with 7 tons of warship!

Thats so funny, I did the same thing today as a joke... I found a H6k Search plane docked at port so just for fun I fired a torpedo at it and blew the thing clear OUT of the water... it easily went like 100 feet in the air and blew to pieces. Then when I looked at what tonnage I got for it , it said 7 tons.
