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.
The December test was part of the effort to equip B-2 bombers to fire the stealthy JASSM-ER.

These missiles are about the same size and weight and fly at similar speeds to the above category. These missiles travel faster than the speed of sound, usually using ramjet engines. The Seoul-based Transitional Justice Working Group had urged South Korea to resume such tests, saying radiation may have spread by rainfall and groundwater. The U.S. and South Korean officials have said the North Korea is likely preparing to conduct its seventh test at the site in Punggye-ri, which would be the first since 2017. In face of the North’s growing threats, South Korea has been seeking stronger reassurances from the United States that it would swiftly and decisively use its nuclear capabilities to defend its ally from a North Korean nuclear attack. During the meeting on Monday, the United States and its allies urged the Security Council to condemn the North’s unlawful ballistic activities, while China and Russia blamed Washington for raising animosity by stepping up its military exercises targeting Pyongyang.
Launch systems
Missile Threat is a product of the Missile Defense Project at the Center for Strategic and International Studies. This led to the adoption of low-level attacks, where the bombers would fly below the radar horizon so they could not be seen on ground-based radars. Quail, originally designed for the high-altitude mission, was modified with the addition of a barometric altimeter to allow it to fly at lower altitudes.
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.
Finally, a new class of air vehicle that blurs the line between a cruise missile and an unmanned aircraft system is gaining traction. When the MC-130J neared the target, it airdropped the Rapid Dragon deployment system carrying the unarmed cruise missile, as well as three weights each simulating the mass and shape of cruise missiles. Within a few seconds, parachutes deployed to stabilize the pallet, and the cruise missile and the weights began to release sequentially to avoid collisions. The missile’s wings and tail popped out, it began to pull up, and then it glided toward its new target. WASHINGTON — The U.S. Air Force conducted a test of its Rapid Dragon palletized munition system concept Nov. 3, which could one day pave the way to launching a barrage of cruise missiles out of the back of mobility aircraft.

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.
While a similar system was also used in SRAM, its shorter range and much shorter flight times meant the drift rate of the system was not a serious concern as long as the bomber could feed it accurate information just before launch, to "zero out" the drift. To provide the accuracy needed to attack the SAM sites with a small warhead, some system was needed to zero out the drift in-flight, and for this need, a radar-based TERCOM system was added. In January 1968, a new requirement emerged for a modern version of Quail for this new mission, the Subsonic Cruise Aircraft Decoy, or SCAD. SCAD was designed specifically to fit onto the same rotary launcher used by SRAM, allowing a single aircraft to carry multiple SRAM and SCAD and launch either at any time. This led to it being the same 14 foot (4.3 m) length as SRAM, and the use of a fuselage with a triangular cross-section, which maximized the usable volume on the rotary launchers.
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.
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.
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.
The ERV flew in August 1979, and was declared the winner of the head-to-head fly-off against the SLCM in March 1980. The first example, similar to the original SCAD in most ways, flew for the first time in March 1976, and its new guidance system was first tested that September. Compared to the models that entered service in the 1980s, the A-model had a distinctive look; the nose tapered sharply to a triangular point giving it a shark-like appearance, compared to the later models which had a more rounded conventional appearance. Looking for another solution to the Soviet SAM problem, in 1964 the Air Force began developing a new system that would directly attack the missile sites rather than confuse them.
By the start of the Persian Gulf War in 1991, Tomahawks had been fitted to surface ships. Land-attack cruise missiles can be launched from the air, ground or sea and because they fly at low altitudes under powered flight, it is difficult for radars to detect them. Lockheed’s AGM-158 JASSM provided the Air Force a stealthy option to strike targets at ranges of up to 500 nm.
Raytheon conducted an active seeker test flight for the Tomahawk Block IV cruise missile in January 2016. The US Navy placed a $338m contract with Raytheon in June 2012 for the delivery of 361 Tomahawk Block IV tactical cruise missiles. Another contract worth $254.6m was awarded for Tomahawk Block IV in the same year.
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.
