The Harpoon missile is quite a dangerous weapon, even though these missiles are not new, are subsonic and fly at a speed of Mach 0.85. Harpoon anti-ship missile systems based on the coast of the Black Sea can be a cause of our concern because they are capable under certain circumstances of breaching even well-organized air and anti-missile defenses. A simultaneous strike by several missiles of this type can lead to the loss of ships.

Measures must be taken to prevent a scenario, in which the Russian infrastructure and the Navy can be threatened by launchers armed with Harpoon missiles capable of hitting targets at a distance of 280 km, the expert stressed.

Citing information from Russian military experts, Harpoon missile systems can target Russian Navy ships and civilian vessels operating in the Black and Azov Seas. The RGM-84 Harpoon cruise missile is versatile and is compatible with various NATO launchers, including Mk 41 vertical launching systems, the expert specified.

On May 25, 2022, the Army Recognition editorial team reported that Denmark had approved the delivery to Ukraine of the Harpoon coastal defense anti-ship missile system. 

The Harpoon Block II is an anti-ship missile manufactured by the American company Boeing. It features autonomous, all-weather, over-the-horizon capability and can execute both land-strike and anti-ship missions. The 227-kg blast warhead delivers lethal firepower against a wide variety of land-based targets, including coastal defense sites, surface-to-air missile sites, exposed aircraft, port or industrial facilities, and ships in port. It has a maximum firing range of around 125 km.
