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. 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.
North Korea says it tested ‘super-large’ cruise missile warhead and new anti-aircraft missile
In the 1970s, when U.S. military planners originally conceived of the cruise missile, the kamikazes were likely not far from anyone’s mind. One weapon that establishes a military power in a completely different category from the rest is the cruise missile. Originally designed to deliver nuclear weapons at long distances, it’s become the go-to weapon for conventional precision strikes, and is currently front and center in Russia’s invasion of Ukraine. In 1995, the US agreed to sell 65 Tomahawks to the UK for torpedo-launch from their nuclear attack submarines. In the Soviet Union, Sergei Korolev headed the GIRD-06 cruise missile project from 1932 to 1939, which used a rocket-powered boost-glide bomb design. The 06/III (RP-216) and 06/IV (RP-212) contained gyroscopic guidance systems.[5] The vehicle was designed to boost to 28 km altitude and glide a distance of 280 km, but test flights in 1934 and 1936 only reached an altitude of 500 meters.
Guidance
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. The air-launched cruise missile (ALCM) had a length of 6.3 m (20.7 feet); it attained a range of 2,500 km (1,500 miles).

The 4,000th Tomahawk Block IV missile was delivered to the US Navy in August 2017. The US Navy warships and submarines launched 66 GPS-enabled Tomahawk missiles at Syrian chemical weapon facilities in 2018. The US Navy will use the upgraded Tomahawk cruise missiles beyond 2040. Raytheon was contracted to integrate the upgraded navigation and communication systems into the Block IV Tactical Tomahawk (TACTOM) missile in March 2020. Army selected the Navy’s Standard Missile-6 (SM-6) and the BGM-109 Tomahawk for its Mid-Range Capability (MRC), part of the service’s ground-launched strike modernization effort.
Everything To Know About Tomahawk Missiles: Speed, Cost, And Destructive Power
In August 2004, the US Navy placed a $1.6bn multi-year procurement contract with Raytheon for 2,200 Tomahawk Block IV missiles. The Block IV Tomahawk missile is outfitted with advanced electronic support measure (ESM) seeker in Block IV Tomahawk missile. Its joint multi-effects warhead enables the commander to control the blast.
Efficiency in modern warfare
Flying low to the surface of the earth expends more fuel but makes a cruise missile very difficult to detect. The Soviet Union and China built ICBMs as well, setting up a world where a nuclear war was deterred by the prospect of mutual assured destruction. Things got real, though, on Jan. 7, 2020, when Iran launched more than a dozen ballistic missiles at two Iraqi military bases housing U.S. troops. It was Iran's retaliation for the U.S. drone strike that killed Iran Gen. Qassem Soleimani on Jan. 3, 2020. There were no casualties and Iran's Foreign Minister Mohammad Javad Zarif defended the missile strike on the U.S. bases in Iraq, saying it was an act of "self-defense."
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). The USAF adopted the AGM-86 for its bomber fleet while AGM-109 was adapted to launch from trucks and ships and adopted by the USAF and Navy.
Navigation
Created out of desperation and meant to curb the inexorable advance of U.S. forces across the Pacific, kamikaze pilots were sent on one-way missions to target ships of the U.S. The planes were loaded with explosives, and the pilots flew low and fast to avoid detection until the last possible moment. Cruise missiles remain within the atmosphere for the duration of their flight and can fly as low as a few meters off the ground.
Tomahawk missile variants
With its long range, ability to be launched practically anywhere in the world from above or below the waves, and its accuracy, the Tomahawk has proved literally thousands of times that it is a vital part of the arsenals of the U.S. According to the Missile Defense Project from the Center for Strategic and International Studies, the Tomahawk (full name Tomahawk Land Attack Missile) has been in service since 1983 and were first developed for the United States Navy starting in 1972. It was designed to be launched from ships or submarines and was, from the outset, made with nuclear payloads in mind. However, nuclear-armed Tomahawks have not been used in combat and are currently deactivated.
HACM is a tactical weapon designed to be used on day one of a large-scale conventional conflict. 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. Work will be executed in various locations across the US until February 2023. 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. It can be armed with a nuclear or unitary warhead or a conventional submunitions dispenser with combined-effect bomblets.
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). In 2017, North Korea unexpectedly staged a test launch of what was then a new ballistic missile, the Pukguksong-2. The launch took place when Japanese Prime Minister Shinzo Abe was on a state visit to the United States. There have been many more test launches of ballistic missiles by North Korea since. Between May and October 2019, North Korea launched as many as 12 ballistic missiles or other projectiles. 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.
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. After the collapse of the Soviet Union, the most recent cruise missile developed was the Kalibr missile which entered production in the early 1990s and was officially inducted into the Russian arsenal in 1994.
Often variants of the same missile are produced for different launch platforms (for instance, air- and submarine-launched versions). During the Cold War, both the United States and the Soviet Union experimented further with the concept, of deploying early cruise missiles from land, submarines, and aircraft. The main outcome of the United States Navy submarine missile project was the SSM-N-8 Regulus missile, based upon the V-1. HACM will be the world’s first operational weapon system to use a scramjet engine. Like turbofan engines, scramjets scoop up oxygen from the surrounding atmosphere to use as fuel. 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.
Tercom uses an on-board 3-D database of the terrain the missile will be flying over. The Tercom system "sees" the terrain it is flying over using its radar system and matches this to the 3-D map stored in memory. The Tercom system is responsible for a cruise missile's ability to "hug the ground" during flight. The GPS system uses the military's network of GPS satellites and an onboard GPS receiver to detect its position with very high accuracy. Some missiles can be fitted with any of a variety of navigation systems (Inertial navigation, TERCOM, or satellite navigation). Larger cruise missiles can carry either a conventional or a nuclear warhead, while smaller ones carry only conventional warheads.
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. Cruise missiles have dramatically changed warfare, as one might expect from a weapon that can fly 1,000 miles and deliver a half-ton high-explosive warhead within 32 feet of a target.
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. Analysts say anti-aircraft missile technology is an area where North Korea could benefit from its deepening military cooperation with Russia, as the two countries align in the face of their separate, intensifying confrontations with the U.S. The United States and South Korea have accused North Korea of providing artillery shells and other equipment to Russia to help extend its warfighting in Ukraine.
