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). Missile Threat brings together a wide range of information and analyses relating to the proliferation of cruise and ballistic missiles around the world and the air and missile defense systems designed to defeat them.

The service’s previous beyond line-of-sight retargeting demonstrations had used a cruise missile emulator. In 2015, for example, a large aerostat being evaluated for cruise missile defense at Aberdeen Proving Ground in Maryland broke free from its mooring and drifted across Pennsylvania. It’s long tether knocked out power lines and, once it landed in a grove of trees in Amish countryside, had to be shot at by State Troopers to get it to deflate. And budget requests during the Trump administration contained little to get moving on cruise missile defense. In President Joe Biden’s first two budgets, the mission also received very little funding save to conduct a cruise missile defense kill chain demonstration. Ballistic missiles can be detected much earlier, which allows more time to detect, track, decide and act.
Block II
Quail was designed in the mid-1950s when the normal attack profile for a strategic bomber was to fly as high and fast as possible to reduce the time the defenders had to respond to the aircraft before it flew out of range. This was effective against interceptor aircraft but of little use against surface-to-air missiles (SAMs), whose attack times were measured in seconds. 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.

That’s enough missiles not only to sink a lot of Chinese warships, but also to bombard Chinese ports and air bases and further degrade the PLA’s logistics. “With each squadron of 12 bombers carrying around 200 stealthy, standoff [cruise missiles], the United States could rapidly cripple the Chinese fleet and leave the invasion force stranded,” the Cancians and Heginbotham wrote. US Navy launch platforms were modified to accommodate upgraded Tomahawk missile variants. Four Ohio class nuclear ballistic missile submarines were converted into cruise missile submarines for firing Tomahawk missiles. The Virginia class submarines and the Royal Navy Astute class submarines were also fitted with new vertical launch modules for Tomahawk missile. 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.

Development was approved in July 1970, and it was given the designation ZAGM-86A, the Z indicating its initial development status. Senior North Korean Foreign Ministry official Kwon Jong Gun denounced the allies’ simulated exercise and visit to the Georgia submarine base, calling the actions an extension of anti-Pyongyang hostility. Security Council held an emergency meeting this week to discuss recent North Korean launches.

RGM / UGM-109D (Block III TLAM-D) is a submunitions dispenser variant armed with 166 combined-effects bomblets. How the architecture would tie into a broader defensive framework with allies and partners such as Canada will require further coordination and analysis. The U.S. and Canada are extensively partnered through a binational command, with capabilities including the North Warning System at the edge of the Arctic designed to detect airborne threats coming from the polar region. The CALCM was also used in Operation Desert Fox in 1998, Operation Allied Force in 1999, and Operation Iraqi Freedom in 2003. Operation Iraqi Freedom was also the combat debut of the AGM-86D, a further development of the missile which replaced the blast/fragmentation warhead of the AGM-86C with a penetrating warhead.
Problematic development
The Tomahawk Land Attack Missile (TLAM) can strike high-value or heavily defended land targets. The missile was first deployed in combat during Operation Desert Storm in 1991. He previously covered leadership and personnel issues at Air Force Times, and the Pentagon, special operations and air warfare at Military.com. The battle management system then uploaded that new data to the weapon on the pallet, allowing it to find its new target. This eliminated the need for ALCM to fit in the B-1's bomb bay, and the length limitations that implied. The Air Force decided to cancel production of the A-model ALCM, and replace it with either an air-launched version of the SLCM, or the ERV.
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. Following the selection, the Army awarded a $339.3 million contract to integrate both weapons for a ground-based launcher by late 2022. Navy sought a precision land attack cruise missile capable of a much smaller CEP. Soon after development began, it was noted that the very small nuclear warheads being developed at that time could be fit to SCAD without seriously affecting its performance as a decoy.

Raytheon was awarded a $207m-worth firm-fixed-price contract in March 2009 for 207 Tomahawk Block IV All-Up-Round (AUR) missiles. The Block Va variants will be named Maritime Strike and have the capability of hitting a moving target.

India is currently developing hypersonic BRAHMOS-II which is going to be the fastest cruise missile.
All three conventional hypersonic cruise missiles are expected to enter service years before the Air Force fields the nuclear LRSO, but the program is making progress. The Air Force selected Raytheon over Lockheed to continue development of the LRSO, which will be armed with an upgraded W80-4 warhead. Two new candidates for a future hypersonic cruise missile are currently in testing, while a third has entered the design phase. A subsonic replacement for a nuclear version of the Boeing AGM-86 air-launched cruise missile is in development. Another replacement for the Navy’s RGM/UGM-109 Tomahawk is on the drawing board and may be adapted for a nuclear role as well. For this role, the accuracy of the original INS guidance hardware was not enough.
The disclosure of the December 2021 test comes amid increased tension between the United States and China. Beijing conducted military drills and ballistic missile launches near Taiwan after high-profile visits to the island by House Speaker Nancy Pelosi and other U.S. lawmakers. Meanwhile, the Air Force had also issued a requirement for a version with a much longer 1,500 nautical miles (2,800 km; 1,700 mi) range. This would allow the bombers to launch their missiles from far off the Russian coast, placing it outside the range of the interceptors as well. To reach the intended range, this new Extended Range Version (ERV) would have to be lengthened to contain more fuel, or external fuel tanks would have to be added. Either change would make it too large to fit on the SRAM launchers and the extended-fuselage version would be too large to fit in the bomb bay of the new B-1 Lancer bomber.
A number of radar jammers and radar reflectors were intended to make it appear like a B-52 on a radar display. 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. 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. The CALCM became operational in January 1991 at the onset of Operation Desert Storm.
Over water, the Tomahawk uses inertial guidance or GPS to follow a preset course; once over land, the missile's guidance system is aided by terrain contour matching (TERCOM). Terminal guidance is provided by the Digital Scene Matching Area Correlation (DSMAC) system or GPS, producing a claimed circular error probable of about 10 meters. A longer video of the test posted by the Pentagon showed the cruise missile traveling over the sea for about 2 minutes before detonating. When asked if a target was destroyed, the lab did not respond directly, but said that all objectives were met.
More than 100 launches have taken place since then, with a 90% approximate success rate. 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.
