Updated artist's impression of the mysterious submersible trimaran built ny China -> www.hisutton.com/Chinese-Semi...

First quality public photo of China’s trimaran semi-sub.

Second image is my sketch based on satellite imagery while it was hidden under tarps(!). Of course some differences, but I was right it is a semi-sub(!). Overall pleased how much I got right

Russian linked shadow fleet tanker Mersin (IMO 9428683) currently sinking off West Africa.

Third picture unladen for reference so you can see how low in the water it now is

Interesting video showing Ukraine’s SBU using surface drones (USVs) to stop Russian linked ‘shadow fleet’ tankers exporting oil from Russia via Black Sea

Delivery of the third and launching of the fourth Scorpène® submarines for the Brazilian navy.

These two major milestones underline the strong technological progress of the Brazilian Navy and the strengthening of its operational capabilities.
