The Harpoon is short ranged, slow, and old. Compare it to the BrahMos.
Dunno if it could cold be effective in today’s environment.
The US Navy needs to update the missile. It looks to be far behind.

Something like Brahmos vs Harpoon is an oranges vs apples comparison. The Harpoon can be deployed by pretty much any surface vessel, sub or aircraft with just electronics modifications.For example, some Indian Jaguars have been equipped with the Harpoon while two Type-209 submarines will also receive the missiles.
Can the same thing be done with the Brahmos? The only Indian aircraft that can “carry” the Brahmos is the SU-30. Work on a smaller version is ongoing, but that’s the basic problem with the missile compared with smaller weapons.
