Research Notes

Common Western anti-ship missile family

medium-high

Harpoon gave ships, aircraft and submarines a common over-the-horizon anti-ship weapon.

The AGM/RGM/UGM-84 Harpoon family is one of the most important Western anti-ship missile systems. The U.S. Navy describes it as an all-weather, over-the-horizon missile used across air and ship launch modes. Its significance comes from creating a common maritime strike weapon that could be fielded on many platforms.

Sea-skimming subsonic maritime strike

The missile’s value is reliable ship attack from multiple launch platforms rather than extreme speed.

Harpoon is a subsonic sea-skimming anti-ship missile, but speed is not its only measure. Its operational value lies in range, platform flexibility, radar terminal guidance and decades of integration. A widely fielded missile can shape naval tactics even when newer weapons offer greater stealth or range.

Legacy weapon still relevant through inventories and upgrades

Harpoon persists because many navies already own launchers, training pipelines and stockpiles.

Harpoon’s service context is about installed base. New missiles such as NSM are gaining ground, but Harpoon remains relevant because it is already integrated on ships and aircraft around the world. In a crisis, available missiles and trained operators matter as much as the newest performance claims.
