If the two match, the missile is on the right flight path; if they don’t match, the missile adjusts course. Programming TERCOM for a long-range mission was a notoriously time-consuming process, and had to be done at a computer terminal. Cruise missiles, although similar to ballistic missiles in some regards, provide an alternate means to deliver a lethal payload rapidly and accurately to a target. Cruise missiles differ from ballistic missiles in that they fly towards their target at lower altitudes, remaining within the Earth’s atmosphere throughout their trajectory. The United States Air Force (USAF) deploys an air-launched cruise missile, the AGM-86 ALCM. The Boeing B-52 Stratofortress is the exclusive delivery vehicle for the AGM-86 and AGM-129 ACM.
Launch Platforms
The Tomahawk is a key weapons system manufactured by RTX, which has sought to maintain its relevance in the evolving battlespace through spiral development and upgrades. As a result, RTX garners a considerable share of the global missile market, partly as a result of the famed TLAM. In 2022, RTX, then Raytheon Technologies, was awarded a $217.1m fixed-price-incentive, firm-fixed-price contract for the full-rate production of Block V Tactical Tomahawk missiles, to be delivered to the US Navy, US Marine Corps, and US Army. The US Navy awarded a $251m contract to Raytheon for the production and delivery of Tomahawk Block IV missiles for both the US Navy and Royal Navy in September 2014.
Efficiency in modern warfare
One key difference between the two is that a turbofan engine scoops up oxygen at subsonic speeds, while a scramjet scoops it up at supersonic speeds. More oxygen means more fuel for the scramjet engine, which enables it to propel the missile even faster. That translates to 11,509 miles per hour, or fast enough to circle Earth in about two hours. A $25.9m contract for Tomahawk missile composite capsule launching systems (C/CLS) was awarded in December 2014.
Why it’s so hard to defend against cruise missiles
Since cruise missiles cost between $500,000 and $1,000,000 each, it's a fairly expensive way to deliver a 1,000-pound package. The United States has deployed nine nuclear cruise missiles at one time or another. A hypersonic cruise missile travels at least five times the speed of sound (Mach 5). The United States Air Force's first operational surface-to-surface missile was the winged, mobile, nuclear-capable MGM-1 Matador, also similar in concept to the V-1. Deployment overseas began in 1954, first to West Germany and later to the Republic of China and South Korea.
What is the Maritime Strike Tomahawk cruise missile?
These missiles have a range of over 1,000 kilometres (620 mi) and fly at about 800 kilometres per hour (500 mph).[37] They typically have a launch weight of about 1,500 kilograms (3,300 lb)[38] and can carry either a conventional or a nuclear warhead. Earlier versions of these missiles used inertial navigation; later versions use much more accurate TERCOM and DSMAC systems. Most of the avowed nuclear powers have technically had hypersonic weapons for a half-century or more, as the ballistic missiles that carry nuclear warheads travel at hypersonic speeds, impacting their targets at up to 15,000 miles per hour. This new generation of hypersonic weapons is different in that it is non-nuclear in nature—at least so far—and would be used immediately in a conventional war. Like many aircraft, turbofan engines power cruise missiles, propelling them at subsonic speeds. Cruise missiles fly low to avoid radar detection, and a slower speed helps them fly lower and hug the ground.
Guidance
SEOUL, South Korea — North Korea said Saturday it tested a “super-large” cruise missile warhead and a new anti-aircraft missile in a western coastal area as it expands military capabilities in the face of deepening tensions with the United States and South Korea. Ballistic missiles first came into use during World War II, when the Germans used a ballistic missile called the V-2 to attack London. British air defenses designed to stop aircraft couldn't stop the V-2s, because the rockets traveled too high into the upper atmosphere and moved too fast. Cruise missiles are unmanned vehicles that are propelled by jet engines, much like an airplane. Asia-Pacific countries such as Japan and Australia have procured Tomahawk Block IV missiles, while in Europe the UK will likely operate them from the Type 26 City-class frigates, currently in build.
The missile has been used 14 more times in combat operations in Syria since its debut. These missiles travel faster than the speed of sound, usually using ramjet engines. The missile continues to ascend toward the highest point in its trajectory, and then begins to descend toward Earth. This is the longest phase of a missile’s flight; for ICBMs, it can last around 20 minutes.
The Tomahawk Block IV version, introduced in the 2010s, included a camera that could send back imagery to the missile’s controllers, allowing a missile to be re-tasked in midair if its target was already destroyed. Block Va, the latest version, adds the ability to target and attack moving ships at sea. Early Tomahawk cruise missiles followed a pre-programmed flight path to target using a system called terrain contour matching (TERCOM). In TERCOM, a radar altimeter scans the terrain below the missile, then compares it to a terrain elevation map stored in its onboard computer brain.
Royal Navy
Despite being powered by rockets and a jet engine, the Tomahawk missile itself isn't that fast, at least comparatively. An F-16 fighter jet tops out at 1,500 miles per hour and the much larger Minuteman III ballistic missile can reach speeds of up to 15,000 miles per hour. Supposedly, the Tomahawk's relatively low speed helps it avoid radar systems more efficiently. Additionally, it flies at an altitude of between 100 and 300 feet, much lower than conventional fighter aircraft.
HACM is a tactical weapon designed to be used on day one of a large-scale conventional conflict. “HACM will provide our commanders with tactical flexibility to employ fighters to hold high-value, time-sensitive targets at risk while maintaining bombers for other strategic targets,” Air Force Chief of Staff Gen. CQ Brown said in an Air Force statement last week. The US signed a foreign military sales (FMS) agreement with the UK in 1995 to supply 65 Tomahawks for use with the Royal Navy nuclear submarines.
Thereafter it is powered by a turbofan engine that does not emit much heat, which makes infrared detection difficult. It can also elude detection by radar because it has a small cross section and operates at low altitudes. Once it reaches land, the Tomahawk uses inertial and terrain-contour-matching (TERCOM) radar guidance, in which a map stored on the missile’s computer is continually compared with the actual terrain to locate the missile’s position relative to the target. As the TERCOM scans the landscape, the Tomahawk missile is capable of twisting and turning like a radar-evading fighter plane, skimming the landscape at an altitude of only 30–90 metres (100–300 feet). In October 2017, Russia began cruise missile strikes against so-called terrorist targets in Syria. These Novator 3M14 Kalibr cruise missiles are very similar to Tomahawk missiles, but use Russia’s GLONASS satellite navigation system, an alternative to the American GPS.

The US Navy warships and submarines launched 66 GPS-enabled Tomahawk missiles at Syrian chemical weapon facilities in 2018. The Tomahawk is designed to operate at very low altitudes while maintaining high-subsonic speeds. Its modular design enables the integration of numerous types of warheads, guidance and control systems. Navy warships fired a total of 288 Tomahawks during Operation Desert Storm in 1991. Tomahawk missiles have also been fired at Bosnia, Sudan, Syria, Yemen, Libya, Somalia, and Afghanistan.
