look at what the net dragged in

[Rhodes]

Now this is a deadliest cast!
A trawler fished last sunday a ww2 bomb in the coast near Nazaré. They notice it after retracting and open the fishing net.
They contact the navy and the bomb was recovered and latter safely detonated under water. Both links are the ones with the most and better pictures of it.

They say that the bomb was a aerial bomb with 206kg of H6, similar to 600kg of TNT. Also, do to the status of corrosion of the surface, no marks were visible.
Any one recognise what kind was it?

Composition H6 is Allied I think, Aussie made, mainly used for naval weapons, but also now used in more than a few US bombs. 200kg is around 450lbs, but it doesn't look a lot like the 450lb depth charge bombs we used which were basically a depth charge from a destroyer with a nose cone and tail fin on it.

You know, I'm going to go out on a bit of a limb here, and say that that might actually not be a WWII bomb but instead a Mk83 GP bomb, which is more Vietnam war era. It's got the look of a Mk 83 without the fins, and the filling charge of the Mk 83 is around 202kg of Tritonal, Minol or Composition H6.

The degradation of the exterior of the bomb could well have taken place since the 1960s, you can see a similar device here:

Although usually the tail fins on the Mk 80 series tend to survive, but I guess being knocked around on the sea bed might have knocked them off.

Just a hunch.

^ That could be more plausible than a WW2 bomb. I think that we only got a few ships and u-boats sunk near our coast.
I also thought first if it could be any shell of a u-boat deck canon, since one was scuttled near Nazaré and the crew went to shore and surrender, when the war ended, but at that time, the deck guns were long gone.

Not to mention that it looks like it's at least a foot in diameter. That'd be one huge deck gun.

I wonder if the flat end means it's detonator had been removed?

Could be, I think the access to the fuze is through a hatch on the tail fin, according to:

They are a very good series of bombs, the 80s, very adaptable.

Meanwhile in London, another present from Hermann Meyer is found.

Agreed, not sure what it is but it looks more modern than WW2 era.
