The RGM-84 Harpoons firing weight is 1,530 pounds, which includes a booster weighing about 362 pounds. The cruising speed is 0.87 Mach and the maximum range is 64nm in Range and Bearing Launch mode and 85nm in Bearing Only Launch mode. The second system is the Tomahawk Weapons System. This is an offensive missile system which gives the Iowa class a very long-range strike capability against both surface and land targets. Each box launcher holds a cluster of 4 missiles.
All variants are similar in appearance and use the same airframe body and launcher.
The firing weight of the Tomahawk is 2,650 pounds plus a 550 pound booster. It has a cruising speed of 0.5 Mach and an attack speed of 0.75 Mach. The USS Wisconsin launches a Tomahawk Missile. Though not as dramatic as a main battery firing, the greater range of the missile allows the battleship to hit targets that would otherwise be unreachable.
