Pretty soon the RPGs will be replaced by FPV drones. Put an explosive drone into the bridge of a merchant ship and it's going to be a mess. I predict that there will be a growing market for drone defenses on merchant ships such as radio jammers and nets over vital spaces.

Radio jammers only work until they figure out the fibre-controlled drones the Ukrainians and Russian's have been making.

Affordable drone defense is something of an unsolved problem right now.

Fiber optic guided drones don't work reliably at sea. The wires drag and break in the water.
