There is an air launched version of the Harpoon for attacking land targets, but that is a different missile than the ones we’ve been sending for coastal defense.
I also don’t think you could just strap one of those to a Fulcrum or Frogfoot and fire it at the Kerch bridge either.
I wonder if one of those robot ships that the US has given Ukraine could get close enough to either launch or explode in an important location.
“It has a wide variety of roles that unmanned surface systems can play, from helping Ukraine monitor surveillance further and further away from its coastline, to potentially assisting in the targeting of Russian ships, when Russia leaves.” To help clear Ukrainian waterways of mines. That route,” said Peter W. Singer, a military technology expert and author of Ghost Fleet, a novel involving the USV and other robotic systems.
Brian Clark, director of the Center for Defense Concepts and Technology at the Hudson Institute, said the ones sent to Ukraine are designed for intelligence, surveillance and reconnaissance (ISR) and countermine operations.
“But I wouldn’t be surprised if Ukrainians, once they start using them, think of ways to put deadly payloads on them,” he said. “Once they’ve got them, Ukrainians can choose to equip them however they want. So, I wouldn’t be surprised if Ukrainians include, you know, maybe some weapon systems out there. be present if they wish to use them to attack Russian ships.
Such weapons could potentially include small missiles that are essentially “guided rockets” or machine guns. Alternatively, Ukrainians could load boats with explosives and ram them into Russian ships like al-Qaeda operatives did to the USS Cole in 2000, he said."
