That's a lot of damage!

Obligatory Flex Seal infomercial to help the ole USS Peleliu stay afloat. The US used our version of USVs to sink a decommissioned LHD last week. Very interesting to see the evolution/copying of tactics and hardware. Whether is's FPV drones, LUCAS one way attack UAVs, or drone boats, the US is piggy-backing off of current wartime technology to rapidly field similar systems.
