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. Raytheon and Northrop Grumman won a contract worth $985 million to develop the world’s first hypersonic cruise missile. HACM, developed for the United States and Australia, is an air-launched hypersonic cruise missile designed to quickly strike targets on the ground. Under the terms of the contract, the Pentagon should see the first operational missiles in 2027. The exact guidance system and navigational dynamics of the Tomahawk missile are classified.
Guidance and control
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. The ABLs were also installed on eight Spruance-class destroyers, the four Virginia-class cruisers, and the nuclear cruiser USS Long Beach.
Hypersonic
The truck-launched versions, and also the Pershing II and SS-20 Intermediate Range Ballistic Missiles, were later destroyed under the bilateral INF (Intermediate-Range Nuclear Forces) treaty with the USSR. HACM is a tactical weapon designed to be used on day one of a large-scale conventional conflict. 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. During midcourse phase, ICBMs can travel around 24,000 kilometers per hour (15,000 miles per hour).
Range and power
The Tomahawk missile itself is a 20.3 foot long craft with a wingspan of eight and a half feet, and it weighs 3,330 pounds with all of its components. It's powered by both a rocket booster and turbofan jet engine made by Williams International. According to PBS, the rocket booster engine launches the Tomahawk in the air (hence all the smoke you may see in news broadcasts or photos you see of the missile) and then its jet engine takes the missile the rest of the way to its target. In this edition of HowStuffWorks, we will look at cruise missiles so that you can understand what they are, how they operate and why they are ideal for certain scenarios.
Fact Sheet: Ballistic vs. Cruise Missiles
Raytheon was awarded a $207m-worth firm-fixed-price contract in March 2009 for 207 Tomahawk Block IV All-Up-Round (AUR) missiles. But as the cruise missile is now in its fifth decade of use, there are signs it’ll need some adjustments to stay relevant on the modern battlefield. In four previous research trips to Kyiv since the invasion, the investigators found that almost all of the advanced Russian military gear they examined — like encrypted radios and laser range finders — was built with Western semiconductors. The US Government approved an agreement in 2003 to deliver 65 Tomahawk Block IV missiles for the UK.

However, it is known that it can use GPS or inertial guidance systems to hit the target. Navy states that up to 15 targets can be pre-programmed for missile salvos. The Tomahawk is capable of "loitering," meaning that, provided the missile has enough fuel, it can fly around in circles to relay information or wait for the right target. It has a range of around 1,500 miles, meaning that the ship or submarine launching the missile is well out of harm's way. More recent cruise missiles, including newer versions of the Tomahawk, have done away with the old navigation systems in favor of using GPS to guide themselves to a fixed target. This has had the effect of making an already accurate missile even more accurate—reportedly to within 32 feet of a target.
During the opening salvos of a regional attack, military planning calls for sea-based Tomahawks to be used to compromise and suppress enemy air operations and defenses. Tomahawks may be retasked in flight, possibly circling for a period before their human handlers select another target for them to attack. Tomahawks can also use their onboard cameras to transmit battle-damage assessment data back to military analysts.
Long-range subsonic
These missiles travel faster than the speed of sound, usually using ramjet engines. The findings are among the most recent by Conflict Armament Research, an independent group based in Britain that identifies and tracks weapons and ammunition used in wars. A small team of its researchers arrived in Kyiv just before the attack at the invitation of the Ukrainian security service. Raytheon received a $349m contract for phase two of the Maritime Strike Tomahawk Rapid Deployment Capability to improve the Tomahawk cruise missile system in August 2019.
A Short History of Cruise Missiles: The Go-To Weapons for Conventional Precision Strikes
The DSMAC system uses a camera and an image correlator to find the target, and is especially useful if the target is moving. A cruise missile can also be equipped with thermal imaging or illumination sensors (as used in smart bombs). A digitized image of an area is mapped and then inserted into a TLAM mission.
Three main versions of the cruise missile were being manufactured in the United States during the mid-1980s. All were single-stage, turbofan jet-propelled missiles with a cruising speed of 885 km per hour (550 miles per hour) and weighed from 1,200 to 1,800 kg (2,700 to 3,900 pounds) each. The missiles were guided by an inertial navigation system that was updated during flight by a technique called Tercom (terrain contour matching), using contour maps stored in the system’s computerized memory.
Terminal Phase begins when the detached warhead(s) reenter the Earth’s atmosphere and ends upon impact or detonation. During this phase, which can last for less than a minute, strategic warheads can be traveling at speeds greater than 3,200 kilometers per hour (1,988 miles per hour). Cruise missiles come in a number of variations (see the links at the end of the article for more information) and can be launched from submarines, destroyers or aircraft.
Work will be executed in various locations across the US until February 2023. Raytheon planned to undertake recertification and modernisation programmes for Tomahawk Block IV missile in 2019 to add maritime strike capability and multiple-effects warhead upgrades to the missiles. Raytheon received a $122m contract from the US Navy in March 2015 for the production of 114 Tomahawk Block IV all-up round missiles. Raytheon conducted an active seeker test flight for the Tomahawk Block IV cruise missile in January 2016.
