The Tomahawk and U S. Cruise Missile Technology

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. Submarine-launched Tomahawk missiles entered service in 1983 with conventional (i.e., nonnuclear) land-attack and antiship missile variants, as well as with a land-attack missile carrying a nuclear warhead. The nuclear variant has since been retired, and a land-attack cluster-bomb variant that disperses bomblets has been added. By the start of the Persian Gulf War in 1991, Tomahawks had been fitted to surface ships.

Due in large measure to its precision, two-way data link and 900 nautical mile range, Tomahawks have long been a “first-to-strike” weapon of war given that they not only bring a standoff ability but can also fire from submarines as well as surface ships. Outside of the Gulf War, Tomahawks were used to attack Iraq several more times in the 1990s, against Bosnian targets in 1995, during NATO actions against Yugoslavia, and during the engagements against Afghanistan after 9/11. More recently, Tomahawks saw use in Libya as part of Operation Odyssey Dawn, ISIS in Syria experienced the effects of Tomahawks, and Syrian chemical weapons facilities used by despot Bashar Al-Assad were struck by Tomahawks in 2017. In 2024, both American and British forces launched Tomahawks against Houthi rebels after the rebel group attacked shipping lanes and US-flagged vessels in the Red Sea. Despite being powered by rockets and a jet engine, the Tomahawk missile itself isn't that fast, at least comparatively.

Long-range subsonic

The U.S. Army’s new ground-based launcher, capable of supporting Tomahawk cruise missiles and SM-6, appeared for the first time in the Indo-Pacific in a deployment to the Northern Philippines for military drills. Between 1957 and 1961 the United States followed an ambitious and well-funded program to develop a nuclear-powered cruise missile, Supersonic Low Altitude Missile (SLAM). It was designed to fly below the enemy's radar at speeds above Mach 3 and carry hydrogen bombs that it would drop along its path over enemy territory. Although the concept was proven sound and the 500-megawatt engine finished a successful test run in 1961, no airworthy device was ever completed.

Everything To Know About Tomahawk Missiles: Speed, Cost, And Destructive Power

At a news conference earlier Thursday marking the end of his second year in Tokyo, Emanuel lauded Japan’s rapid move during that time to build up its military and strengthen its alliance with the U.S. to meet challenges in the region. Prime Minister Fumio Kishida’s government has pledged to double its annual defense spending to around 10 trillion yen ($68 billion) by 2027, which would make Japan the world’s third-biggest military spender after the United States and China. Clark, the Hudson analyst, agreed that the mix was important, saying that even with the arrival of faster missiles, the Tomahawk has a place. “It has greater electronic hardening to be able to work through jamming more effectively,” Clark said.

Block II introduced land attack capabilities, like those demonstrated during the 1991 Gulf War, with missiles striking Iraqi Air Force airfields and daytime targets across the Iraqi capital of Baghdad. Block III added GPS, eliminating a time-consuming programming system that required 80 hours to plot a missile’s course as well as a loitering capability. Unlike the Navy, however, the Air Force kept a hand in cruise missile technology. Early systems, such as the Matador, Snark, and the ambitious Navaho, lived on in newer operational versions like the Hound Dog, which flew aboard B-52 long-range strategic bombers. Then, in the 1970s, the Air Force debuted the Air Launched Cruise Missile (ALCM) that bore a close resemblance in performance and capabilities to the Tomahawk.

Based on comparison results the missile's inertial navigation system is updated and the missile corrects its course. ADM Zumwalt also saw the inclusion of SLCMs aboard surface ships as one final triumph over Rickover. Admiral Locke greatly credits their vision and assistance during the early formation years of the cruise missile. “The MRC deployment aims to enhance Philippine maritime defense capabilities, while bolstering interoperability and readiness within the U.S.-Philippine Alliance,” states the press release. India is currently developing hypersonic BRAHMOS-II which is going to be the fastest cruise missile. These missiles are about the same size and weight and fly at similar speeds to the above category.

Further back, in August 2019 Raytheon received a $349m contract for phase two of the MST Rapid Deployment Capability to improve the Tomahawk cruise missile system. 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 two-way satellite communications are used to perform post-launch mission changes throughout the flight. The on-board camera provides imagery of the target to the commanders before the strike. It can be armed with a nuclear or unitary warhead or a conventional submunitions dispenser with combined-effect bomblets. The Block Va variants will be named Maritime Strike and have the capability of hitting a moving target.

Raytheon was contracted to integrate the upgraded navigation and communication systems into the Block IV Tactical Tomahawk (TACTOM) missile in March 2020. Tomahawk is a long-range, all-weather, subsonic cruise missile in service with the surface ships and submarines of the US and the UK’s Royal Navy. Originally produced by General Dynamics, Tomahawk is currently manufactured by Raytheon. In this first-ever deployment, the 1st MDTF stationed out of the continental United States at Joint Base Lewis-McChord, Washington deployed Typhon on a U.S. Over 8,000 miles and 15 hours later, America’s first ground-based cruise missile launcher since the Cold War rolled onto Philippine soil at an unidentified airfield in Northern Luzon for the bilateral U.S.-Philippine ground forces exercise Salaknib 2024. In recent years, activities in Salaknib have shifted to include higher-end drills, such as coastal defense, amid the Philippine military’s shift from internal security operations to archipelagic coastal defense.

“And if they can get it down to being able to fit in [the Mark 41], then that could provide the Navy a next-generation capability that is more survivable and has a shorter time of flight. Tomahawk missiles have been world famous since the first Gulf War in 1991 when the United States used the missile against Saddam Hussein's forces in Iraq and Kuwait. Since then, the missile system has been used in nearly every conflict the United States has been involved in, including recent strikes against Houthi rebels in Yemen. Given the weapon's ubiquity, it's worth exploring what exactly a Tomahawk missile is.

Tomahawks can also use their onboard cameras to transmit battle-damage assessment data back to military analysts. In May 2022, the UK announced that its stock of Block IV TLAM munitions were to be upgraded to the Block V variant for specific use in the Astute-class submarines. The Block V, according to UK Defence Equipment and Support, an arm of the Ministry of Defence, would have a longer range than the Block IV at up to 1,000 miles, and also has updated in-flight communications and target selection. Japan planned to upgrade all eight of its Aegis destroyers to install Tomahawk cruise missiles, and Australia requested a sale of $895m for Tomahawk missiles from the US to boost their maritime capabilities and improve interoperability earlier this year. The US Navy placed a $338m contract with Raytheon in June 2012 for the delivery of 361 Tomahawk Block IV tactical cruise missiles.

….The ACM program of 1971, which barely lasted two years, was significant in that it formed the political, fiscal, and technological connection between the Harpoon and the Tomahawk. Long-range cruise missile advocates within the Navy were having difficulty promoting the larger submarine-launched cruise missile because of the ACM’s need for a new submarine. In 1973, they admitted they had no urgent military requirement for a long-range tactical (anti-ship) variant of the SLCM, but they justified it as a bargain with small added cost to strategic cruise missile development. SLCM represented a technological advancement of untold potential that begged for a home.

Worth noting, however, is that the enthusiasm of many early Harpoon and Tomahawk advocates can be linked to the Regulus and other unmanned aircraft programs of the 1950s and 1960s. 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. Both missile types are configurable for either conventional or nuclear warheads.

The most common mission for cruise missiles is to attack relatively high-value targets such as ships, command bunkers, bridges and dams.[52] Modern guidance systems permit accurate attacks. Built to counter Soviet air defenses years ago, Tomahawks often fly parallel to the surface of the ocean to elude enemy radar. The combat success of the Tomahawk, and the Army’s need for ground-based fires at longer ranges, has inspired what is now an emerging land-launched Tomahawk variant to enter service in the next year or two. US Navy launch platforms were modified to accommodate upgraded Tomahawk missile variants.

The UGM-109A Tomahawk (Block II TLAM-A) carries a W80 nuclear warhead. The Tomahawk Land Attack Missile (TLAM) can strike high-value or heavily defended land targets. The Block II TLAM-A missile achieved initial operating capability in 1984. The missile was first deployed in combat during Operation Desert Storm in 1991. After initial interest and planning (2005), the Dutch Ministry of Defence in 2023 confirmed ordering the ship launched- and submarine launched versions of the Tomahawk to be installed on both existing as well as future frigates & submarines. After achieving flight, the missile's wings are unfolded for lift, the airscoop is exposed and the turbofan engine is employed for cruise flight.

RGM / UGM-109E Tomahawk (Block IV TLAM-E) is the latest member in the Tomahawk missile family. It carries a 1,000lb-class unitary warhead for a maximum range of 900nmi. A digitized image of an area is mapped and then inserted into a TLAM mission. During the flight the missile will verify that the images that it has stored correlates with the image it sees below itself.
