Tomahawk is a cruise missile that, according to the modification, can be launched from the sea or land, respectively from a ship, submarine, or surface-to-surface missile system. Block V Tactical Tomahawk differs from its predecessors mainly in the increased range of 1666+ km.

After launch, the rocket is powered by a Williams International F107-WR-402 turbofan engine, which uses a TH-dimer fuel and a solid-fuel rocket booster. Tomahawk’s wingspan is 8 ft 9 in [2.67 m]. The rocket flies at an altitude of 98-164 ft [30-50 m] AGL and develops a subsonic speed of Mach 0.74. which is about 567.7 mph [493.3 kn; 913.6 km / h]. The missile guidance system includes the integration of several key systems: GPS, INS, TERCOM, DSMAC, and active radar homing [RGM / UGM-109B]. The warhead is conventional: 1,000 pounds [450 kg] high explosive or submunition dispenser with BLU-97 / B Combined Effects Bomb or PBXN.

PBXN-9 is a PBX or polymer-bonded explosive warhead, also called PBX or plastic-bonded explosive. This type of explosive uses a very small amount of synthetic polymer and is part of the explosive powder in the charge matrix. It has been developed since the early 1950s, but only in the 1960s and 1970s did it find application in the warheads of various projectiles.

A quick look shows that the PBX is widely used in various warheads, some high-speed missiles, and projectiles, such as nuclear W62, W70, W68, W79, W82, and many others. PBX is found in the Mk-48 torpedo, as well as in the jet-powered supersonic cruise missile BGM-109 Tomahawk and short-range AIM-9X Sidewinder missile. In recent years, PBX warheads have found wide application in the development of naval artillery missiles.

The new 154 missiles for the United States will be manufactured by Raytheon Missiles and Defense, Tucson, Arizona. The quantity is expected to be delivered by 2025 and distributed as follows: 70 for the Navy, 54 for the Marine Corps, and 30 for the Army.
