Sorry, I'm aware of it's delivery but was somewhat bewildered by the fact the builders plate was removed prior to this delivery mission and the fact that the crew wasn't rescued for something like 4 days after the ship sunk. Why did the navy do this? was it a nme torp? inquiring minds with nothing else better to do want to know

Why was it removed? 'they' said so uncle sam could deny it's ID as a U.S. warship in case it was caught.
Im sure there's a resonable explanation why this plate was removed I just don't know what it is. Maybe what 'they said is true about the denial story. But what's there to deny if it got caught? and caught at doing what? delivering a bomb? you'd think they would've had a method of disposing of it at sea instead of allowing to fall in nme hands and say to them what bomb? I don't see no bomb. U.S. warship? you mean this old thing?
should add that as far as I know these gents could be pullin my leg, maybe the plate was recovered? ya got me
