The Joint Direct Attack Munition ( JDAM ) is a guidance kit that converts unguided bombs , or "dumb bombs", into all-weather precision-guided munitions (PGMs). JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles (28 km). JDAM-equipped bombs range from 500 to 2,000 pounds (230 to 910 kg). The JDAM's guidance system was jointly developed by the United States Air Force and United States Navy , hence the "joint" in JDAM. When installed on a bomb, the JDAM kit is given a GBU (Guided Bomb Unit) identifier, superseding the Mark 80 or BLU (Bomb, Live Unit) nomenclature of the bomb to which it is attached.
94-741: The JDAM is not a stand-alone weapon; rather it is a "bolt-on" guidance package that converts unguided gravity bombs into PGMs. The key components of the system are a tail section with aerodynamic control surfaces, a (body) strake kit, and a combined inertial guidance system and GPS guidance control unit. The JDAM was meant to improve upon laser-guided bomb and imaging infrared technology, which can be hindered by bad ground and weather conditions. Laser seekers are now being fitted to some JDAMs. From 1998 to November 2016, Boeing completed more than 300,000 JDAM guidance kits. In 2017 it built more than 130 kits per day. As of January 2024, 550,000 kits had been produced. The U.S. Air Force 's bombing campaign during
188-575: A GPS signal is available. If the GPS signal is jammed or lost, the JDAM can still achieve a 98-foot (30 m) CEP or less for free flight times up to 100 seconds. The introduction of GPS guidance to weapons brought several improvements to air-to-ground warfare. The first is a real all-weather capability since GPS is not affected by rain, clouds, fog, smoke, or artificial obscurants. Previous precision guided weapons relied on seekers using infrared, visual light, or
282-622: A Tomahawk from the Typhon missile launcher . The TLAM-D contains 166 sub-munitions in 24 canisters: 22 canisters of seven each, and two canisters of six each to conform to the dimensions of the airframe. The sub-munitions are the same type of Combined Effects Munition bomblet used in large quantities by the US Air Force with the CBU-87 Combined Effects Munition . The sub-munitions canisters are dispensed two at
376-711: A contract with Boeing to become the first international customer of LJDAM. Deliveries for the German Air Force began in mid-2009. The order also includes the option for further kits in 2009. Boeing announced in September 2008 that it had conducted demonstration flights with the LJDAM loaded aboard a B-52H . The GBU-54 LJDAM made its combat debut in August 2008 in Iraq when an F-16 from the 77th Fighter Squadron engaged
470-471: A decade earlier, was equipped with inertial guidance and the seeker of the Harpoon missile and there was concern with its ability to clearly discriminate between targets from a long distance, since at the time Navy sensors did not have as much range as the missile itself, which would be more reliable with the new seeker's passive detection and millimeter-wave active radar homing . Raytheon estimates adding
564-685: A ground-based SM-6 and field them by late 2023. In 1995, the US agreed to sell 65 Tomahawks to the UK for torpedo-launch from their nuclear attack submarines. The first missiles were acquired and test-fired in November 1998; all Royal Navy fleet submarines are now Tomahawk capable, including the Astute -class . The Kosovo War in 1999 saw the Swiftsure-class HMS Splendid become
658-498: A jet engine tailkit to the JDAM-ER for 10 times greater range. The U.S. Air Force initially showed no interest in the concept, but by 2020 Boeing believed the service had regained interest in acquiring low-cost cruise missiles. The Powered JDAM combines a 500 lb (230 kg) bomb with a wing kit and a propulsion module, giving it the range of more sophisticated missiles through a low-cost engine while being cheaper though not having
752-509: A loitering feature in the missile's flight path and allows commanders to redirect the missile to an alternative target, if required. It can be reprogrammed in-flight to attack predesignated targets with GPS coordinates stored in its memory or to any other GPS coordinates. Also, the missile can send data about its status back to the commander. It entered service with the US Navy in late 2004. The Tactical Tomahawk Weapons Control System (TTWCS) added
846-413: A loosely defined area, they can be laid directly into harbor mouths, shipping channels, canals, rivers, and inland waterways, reducing the number of mines required and enhancing the possibility of blocking ship transit corridors. Enemy naval ports can be blockaded, and a defensive minefield quickly planted to protect areas threatened by amphibious assault . A direct-attack bomb version called "Quicksink"
940-522: A lower cost. Although Russian air defenses force Ukrainian aircraft to fly at extremely low levels, they could pop up and release the bombs on a lofted trajectory to glide toward a target. Ukrainian platforms needed modifications to employ the weapons, as had been done with the AGM-88 HARM . The JDAM-ER was already in use by the Ukrainians by the time of the reports of its delivery. Yuriy Ignat,
1034-681: A moving vehicle in Diyala province. The GBU-54 LJDAM made its combat debut in the Afghan theater by the 510th Fighter Squadron in October 2010. In September 2012, Boeing began full-rate production of Laser JDAM for US Navy and received a contract for more than 2,300 bomb kits. In November 2014, the U.S. Air Force began development of a version of the GBU-31 JDAM intended to track and attack sources of electronic warfare jamming directed to disrupt

#17327799637261128-770: A new arms race . Spain (2002 and 2005) was interested in acquiring the Tomahawk system, but the order was later cancelled in 2009. In 2009, the Congressional Commission on the Strategic Posture of the United States stated that Japan would be concerned if the TLAM-N were retired, but the government of Japan has denied that it had expressed any such view. The SLCM version of the Popeye
1222-555: A new target in flight and can transmit an image, via satcom , immediately before impact to help determine whether the missile is on target and the likely damage from the attack. A major improvement to the Tomahawk is network-centric warfare -capabilities, using data from multiple sensors (aircraft, UAVs , satellites, foot soldiers, tanks, ships) to find its target. It will also be able to send data from its sensors to these platforms. Tomahawk Block II variants were all tested during January 1981 to October 1983. Deployed in 1984, some of
1316-459: A new warhead designed to give the Tomahawk the same blast-fragmentation capabilities while introducing enhanced penetration capabilities in a single warhead. In the static test, the warhead detonated and created a hole large enough for the follow-through element to completely penetrate the concrete target. In February 2014, US Central Command sponsored development and testing of the JMEWS, analyzing
1410-492: A precision terminal guidance seeker in the JDAM kit. The Laser JDAM (LJDAM), as this upgrade is known, adds a laser seeker to the nose of a JDAM-equipped bomb, enabling it to engage moving targets. The laser seeker is a cooperative development between Boeing 's Defense, Space and Security unit and Israel's Elbit Systems . It is called the Precision Laser Guidance Set (PLGS) by Boeing and consists of
1504-643: A radical concept that used GPS. At the time, there were few GPS satellites and the idea of using satellite navigation for real-time weapon guidance was untested and controversial. To identify the technical risk associated with an INS/GPS guided weapon, the Air Force created in early 1992 a rapid-response High Gear program called the "JDAM Operational Concept Demonstration" (OCD) at Eglin Air Force Base. Honeywell , Interstate Electronics Corporation, Sverdrup Technology, and McDonnell Douglas were hired to help
1598-585: A reflected laser spot to "see" the ground target. These seekers were not effective when the target was obscured by fog and low altitude clouds and rain (as encountered in Kosovo), or by dust and smoke (as encountered in Desert Storm). The second advantage is an expanded launch acceptance region (LAR). The LAR defines the region that the aircraft must be within to launch the weapon and hit the target. Non-GPS based precision guided weapons using seekers to guide to
1692-401: A ship passes within lethal range, a safe/arm device in the nose, and a parachute-retarder tailkit in the back. Dropping of naval mines has historically been challenging, as the delivery aircraft has to fly low and slow, 500 ft (150 m) at 320 knots (370 mph; 590 km/h), making it vulnerable to hostile fire. The first aerial mining mission of Operation Desert Storm resulted in
1786-477: A spokesman for Air Force Command of the Ukrainian Armed Force, told Ukrainian TV that: "These bombs (JDAM) are slightly less powerful, but extremely accurate. I would like to have more such bombs for success at the front." This comment might be a reference to the fact that these bombs are 500 pounds. As to how many were supplied one US official said "enough to do a couple of strikes." On 26 April,
1880-626: A stealthy shape or the ability to conduct low-altitude flights. Though less survivable, Powered JDAMs could be networked to provide a cheap standoff weapon to overwhelm air defense systems. In late February 2023, it was revealed that JDAM-ERs would be provided to the Ukrainian Air Force as part of an arms package during the Russian invasion of Ukraine . With a standoff range of up to 72 km (45 mi), it delivers similar range to M142 HIMARS rockets, but with heavier warheads and at
1974-456: A system reliability in excess of 95% with a published accuracy under 33-foot (10 m) CEP. In addition to controlled parameter drops, the testing and evaluation of the JDAM also included "operationally representative tests" consisting of drops through clouds, rain and snow with no decrease in accuracy from clear-weather tests. In addition, there have been tests involving multiple weapon drops with each weapon being individually targeted. JDAM and

#17327799637262068-405: A target. Weapon trajectories can be controlled so that a target can be impacted at precise headings and vertical angles. This provides the ability to impact perpendicular to a target surface and minimize the angle of attack (maximizing penetration), detonate the warhead at the optimum angle to maximize the warhead effectiveness, or have the weapon fly into the target area from a different heading than
2162-491: A time, one per side. The missile can perform up to five separate target segments which enables it to attack multiple targets. However, in order to achieve a sufficient density of coverage typically all 24 canisters are dispensed sequentially from back to front. TERCOM – Terrain Contour Matching. A digital representation of an area of terrain is mapped based on digital terrain elevation data or stereo imagery. This map
2256-604: Is an American long-range, all-weather, jet-powered, subsonic cruise missile that is primarily used by the United States Navy and Royal Navy in ship and submarine-based land-attack operations. Developed at the Applied Physics Laboratory of Johns Hopkins University under James H. Walker near Laurel, Maryland, the Tomahawk emerged in the 1970s as a modular cruise missile first manufactured by General Dynamics . The Tomahawk aimed to fulfill
2350-405: Is have an uninterrupted Line-of-Sight (LOS) with – at least four satellites", and will "often" have more satellites available to it. Thus, blocking signals from one direction might not affect the receiver's ability to "see" other satellites. Russian forces may choose to respond by placing more jammers in order to deny a line of sight to the satellites that it requires. Russian EW units might also have
2444-507: Is stored and launched from a pressurized canister that protects it during transportation and storage, and also serves as a launch tube. These canisters were racked in Armored Box Launchers (ABL), which were installed on the four reactivated Iowa -class battleships USS Iowa , USS New Jersey , USS Missouri , and USS Wisconsin . The ABLs were also installed on eight Spruance -class destroyers ,
2538-618: Is sufficient fuel left in the case of a short-range target. Tomahawk Block V was introduced in 2021 with improvements to navigation and in-flight targeting. Block Va, the Maritime Strike Tomahawk (MST) which allows the missile to engage a moving target at sea, and Block Vb outfitted with the JMEWS warhead for hard-target penetration, will be released after the initial batch of Block V is delivered in March 2021. All Block IV Tomahawks will be converted to Block V standard, while
2632-409: Is the first advance in aerial mine delivery techniques since World War II. It can increase the survivability of delivery aircraft, since instead of making multiple slow passes at low altitude directly over the area, an aircraft can release all of their mines in a single pass from a standoff distance and altitude. This increases the mines' effectiveness, since instead of laying a random pattern of mines in
2726-433: Is then inserted into a TLAM mission which is then loaded onto the missile. When the missile is in flight it compares the stored map data with radar altimeter data collected as the missile overflies the map. Based on comparison results the missile's inertial navigation system is updated and the missile corrects its course. TERCOM was based on, and was a significant improvement on, "Fingerprint," a technology developed in 1964 for
2820-649: Is unavailable, with the same accuracy of the earlier JDAM. In June 2007, Boeing announced that it had been awarded a $ 28 million contract by the U.S. Air Force to deliver 600 laser seekers (400 to the Air Force and 200 to the Navy) by June 2009. According to the Boeing Corporation, in tests at Nellis Air Force Base , Nevada , Air Force F-16 Fighting Falcons and F-15E Strike Eagles dropped twelve 500 lb (230 kg) LJDAMs that successfully struck high-speed moving targets. Using onboard targeting equipment,
2914-576: The B-2 Spirit stealth bomber made their combat debuts during Operation Allied Force . The B-2s, flying 30-hour, nonstop, round-trip flights from Whiteman Air Force Base , Missouri , delivered more than 650 JDAMs during Allied Force. An article published in the Acquisition Review Journal in 2002 cites that "during Operation Allied Force ... B-2s launched 651 JDAMs with 96% reliability and hit 87% of intended targets..." Due to

The United States Defense Security and Cooperation Agency announced on 17 November 2023 that the US State Department had approved a possible sale of up to 200 RGM-109E Tomahawk Block IV and up to 200 RGM-109E Tomahawk Block V LACMs to Japan for an estimated US$ 2.35 billion. After initial interest and planning (2005), the Dutch Ministry of Defence in 2023 confirmed ordering
3196-622: The Persian Gulf War 's Operation Desert Storm was less effective than initially reported, in part because it had no precision bombs that were accurate in all types of weather. Laser guidance packages on bombs proved exceptionally accurate in clear conditions, but amid airborne dust , smoke , fog , or cloud cover, they had difficulty maintaining "lock" on the laser designation. Research, development, testing and evaluation (RDT&E) of an "adverse weather precision guided munition" began in 1992. Several proposals were considered, including

In March 2023, the US State Department approved a Foreign Military Sale to sell Australia of up 200 Block V and up to 20 Block IV missiles worth an estimated $ US895 million. The sale was approved by the United States State Department for US$ 250 million on 11 January 2024. The Japanese government is negotiating with the US government to purchase US-made Tomahawk cruise missiles for attacking enemy bases and counterattack purposes. The Japanese government decided to purchase
3384-464: The SLAM . DSMAC – Digital Scene Matching Area Correlation. 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. Based on comparison results the missile's inertial navigation system is updated and the missile corrects its course. GPS – The Tomahawk relies on
3478-719: The Digital Scene Matching Area Correlation (DSMAC) II navigation system, allowing three kinds of navigation: GPS-only, which allow for rapid mission planning, with some reduced accuracy, DSMAC-only, which take longer to plan but terminal accuracy is somewhat better; and GPS-aided missions that combine DSMAC II and GPS navigation for greatest accuracy. Block IV TLAMs have an improved turbofan engine that allows them to get better fuel economy and change speeds in flight. The Block IV TLAMs can loiter better and have electro-optical sensors that allow real-time battle damage assessment. The Block IVs can be given

In September 2014, the U.S. Air Force performed the first-ever drop of a precision-guided aerial sea mine , consisting of a Quickstrike mine equipped with a JDAM kit. The Quickstrike is a Mark 80-series general-purpose bomb with the fuze replaced with a target detection device (TDD) to detonate it when
4230-643: The USAF 46th Test Wing demonstrate the feasibility of a GPS weapon within one year. The OCD program fitted a GBU-15 guided bomb with an INS/GPS guidance kit and on 10 February 1993, dropped the first INS/GPS weapon from an F-16 on a target 88,000 feet (27 km) downrange. Five more tests were run in various weather conditions, altitudes, and ranges. The OCD program demonstrated a 36-foot (11 m) Circular Error Probable (CEP). The first JDAM kits were delivered in 1997, with operational testing conducted in 1998 and 1999. During testing, over 450 JDAMs were dropped achieving
4324-592: The United States Navy conducted a test flight of a Tomahawk missile launched from a ground-based version of the Mark 41 Vertical Launch System . It was the United States' first acknowledged launch of a missile that would have violated the 1987 Intermediate-Range Nuclear Forces Treaty, from which the Trump administration withdrew on 2 August after Russia broke it. The United States Army has successfully launched

After achieving flight, the missile's wings are unfolded for lift, the airscoop is exposed and the turbofan engine is employed for cruise flight . Over water, the Tomahawk uses inertial guidance or GPS to follow a preset course; once over land,
4606-705: The WSJ report stated that US arms shipments to Israel since the start of the Israel–Hamas war included approximately 3,000 JDAMs. Israeli F-15I fighter jets are believed to have used BLU-109 bunker buster bombs with JDAM guidance kits in the strikes that killed Hezbollah leader Hassan Nasrallah in Beirut, Lebanon on 27 September 2024. Experience during Operation Enduring Freedom and Operation Iraqi Freedom led US air power planners to seek additional capabilities in one package, resulting in ongoing program upgrades to place
4700-615: The ability of the programmable warhead to integrate onto the Block IV Tomahawk, giving the missile bunker buster effects to better penetrate hardened structures. In 2012, the USN studied applying Advanced Anti-Radiation Guided Missile (AARGM) technology into the Tactical Tomahawk. In 2014, Raytheon began testing Block IV improvements to attack sea and moving land targets. The new passive radar seeker will pick up
4794-525: The ability to spoof or fake the M-Code that it confuses the JDAM as to its location and time. Ukrainian forces have been able to locate Russian jammers and hit them with "kinetic" attacks such as artillery. Several Russian EW units have been targeted and lost equipment. On 13 August 2024, Ukrainian Su-27 launched a JDAM at a Russian command post in Tetkino , which was reportedly destroyed. In December 2023,

#17327799637264888-522: The aircraft to fly generally straight at the target when launching the weapon. This restriction is eased in some other systems, such as the GBU-15 and the AGM-130 , through the ability of a Weapon System Operator (WSO) in the aircraft to manually steer the weapon to the target. Using a WSO requires a data link between the weapon and the controlling aircraft and requires the controlling aircraft to remain in
4982-451: The aircraft. The third advantage is a true " fire-and-forget " capability in which the weapon does not require any support after being launched. This allows the launching aircraft to leave the target area and proceed to its next mission immediately after launching the GPS guided weapon. Another important capability provided by GPS-based guidance is the ability to completely tailor a flight trajectory to meet criteria other than simply hitting
5076-407: The area (and possibly vulnerable to defensive fire) as long as the weapon is under manual control. Since GPS-based flight control systems know the weapon's current location and the target location, these weapons can autonomously adjust the trajectory to hit the target. This allows the launch aircraft to release the weapon at very large off-axis angles including releasing weapons to attack targets behind
5170-458: The battle, thereby causing the device to return to "default" and "display its own coordinates." Not realizing that this had occurred, the TACP relayed his own coordinates to the delivery aircraft. On 5 May 2023, during the 2022 Russian invasion of Ukraine , MSN reported that Russia was able to jam the GPS guidance system to cause JDAMs to miss their targets. The leaked Pentagon document described
5264-481: The capability for limited mission planning on board the firing unit (FRU). Tomahawk Block IV introduced in 2006 adds the strike controller which can change the missile in flight to one of 15 preprogrammed alternate targets or redirect it to a new target. This targeting flexibility includes the capability to loiter over the battlefield awaiting a more critical target. The missile can also transmit battle damage indication imagery and missile health and status messages via
5358-463: The designated target coordinates. Target coordinates can be loaded into the aircraft before takeoff, manually altered by the aircrew in flight prior to weapon release, or entered by a datalink from onboard targeting equipment, such as the LITENING II or "Sniper" targeting pods. In its most accurate mode, the JDAM system will provide a minimum weapon accuracy CEP of 16 feet (5 m) or less when

It also had an extremely bright strobe light it could use to illuminate the ground for fractions of a second in order to find its position at night, and was able to take the difference in ground appearance into account. Tomahawk Block III introduced in 1993 added time-of-arrival control and improved accuracy for Digital Scene Matching Area Correlator (DSMAC) and jam-resistant GPS , smaller, lighter WDU-36 warhead, engine improvements and extended missile's range. Tactical Tomahawk Weapons Control System (TTWCS) takes advantage of
5922-467: The improvements included: an improved booster rocket, cruise missile radar altimeter, and navigation through the Digital Scene Matching Area Corellator (DSMAC). DSMAC was a highly accurate rudimentary AI which allowed early low power computers to navigate and precisely target objectives using cameras on board the missile. With its ability to visually identify and aim directly at a target, it was more accurate than weapons using estimated GPS coordinates. Due to

6392-429: The mentioned steps to increase jamming resiliency, the "sheer brute force" of a powerful jamming signal can prevent the JDAM's global navigation satellite system (GNSS) receiver from obtaining the encrypted signal. Counter-EW systems, while classified, might allow a JDAM to recognize a jamming signal and its direction and "block out" signals coming from that direction. A GNSS receiver will "typically need to 'see' – that
6486-538: The missile include: BGM-109G Ground Launched Cruise Missiles (GLCM) and their truck-like launch vehicles were employed at bases in Europe; they were withdrawn from service to comply with the 1987 Intermediate-Range Nuclear Forces Treaty . Many of the anti-ship versions were converted into TLAMs at the end of the Cold War . The Block III TLAMs that entered service in 1993 can fly farther using their new turbofan engines and use Global Positioning System (GPS) receivers to strike more precisely. Block III TLAM-Cs retain
6580-568: 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 30 feet (10 m). The Tomahawk Weapon System consists of the missile, Theater Mission Planning Center (TMPC)/Afloat Planning System, and either the Tomahawk Weapon Control System (on surface ships) or Combat Control System (for submarines). Several versions of control systems have been used, including: On 18 August 2019,
6674-420: The munitions' guidance. The Home-on-Jam seeker works similar to the AGM-88 HARM to follow the source of a radio-frequency jammer to destroy it. In 2006, the Australian Defence Science and Technology Organisation in conjunction with Boeing Australia successfully tested extended range 500 lb (230 kg) JDAM variants at the Woomera Test Range . In 2009, Boeing announced that it will jointly develop
6768-409: The need for a medium- to long-range, low-altitude missile with diverse capabilities. Its modular design allows for compatibility with a range of warheads, including high-explosive, submunitions, and bunker-busters. The Tomahawk can use a variety of guidance systems, including GPS , inertial navigation , and terrain contour matching . Over a dozen variants and upgraded versions have been developed since
6862-468: The new Type 26 frigates and the Type 31 frigate will be filled with strike-length Mk41 VLS. In June 2022, the UK announced it would be upgrading its Tomahawk cruise missiles to Block V standard through a £265 million contract with the US government. The missiles will be upgraded from 2024. In September 2021, Australian Prime Minister Scott Morrison announced that Australia would acquire Tomahawks for
6956-581: The new Type 45 destroyer is claimed by its manufacturers to have the capability to fire the Tomahawk, although the A50 launcher carried by the Type 45 is too short for the weapon (the longer A70 silo would be required). Nevertheless, the Type 45 has been designed with weight and space margin for a strike-length Mk41 or Sylver A70 silo to be retrofitted, allowing Type 45 to use the TLAM Block IV if required. Both
7050-634: The new generation of Tomahawk missile—the Block IV or TacTom missile. It entered service with the Royal Navy on 27 March 2008, three months ahead of schedule. In July 2014 the US approved the sale to the UK of a further 65 submarine-launched Block IV's at a cost of US$ 140m including spares and support; as of 2011 the Block III missiles were on British books at £1.1m and the Block IV at £0.87m including VAT. The Sylver Vertical Launching System on
7144-463: The new seeker would cost $ 250,000 per missile. Other upgrades include a sea-skimming flight path. The first Block IV TLAMs modified with a maritime attack capability will enter service in 2021. A supersonic version of the Tomahawk is under consideration for development with a ramjet to increase its speed to Mach 3. A limiting factor to this is the dimensions of shipboard launch tubes. Instead of modifying every ship able to carry cruise missiles,
7238-493: The newest Tomahawk cruise missile, dubbed the Tactical Tomahawk , costs nearly $ 730,000 (FY 2006). Guidance is facilitated through a tail control system and a GPS -aided inertial navigation system (INS). The navigation system is initialized by transfer alignment from the aircraft that provides position and velocity vectors from the aircraft systems. Once released from the aircraft, the JDAM autonomously navigates to
7332-613: The operational success of the original JDAM, the program expanded to the 500-pound (230 kg) Mark 82 and 1,000-pound (450 kg) Mark 83 , beginning development in late 1999. As a result of lessons from Operation Enduring Freedom and Operation Iraqi Freedom , both the US Navy and US Air Force pursued improvements to the kits such as better GPS accuracy as well as a precision seeker for terminal guidance for use against moving targets. JDAM bombs are inexpensive compared to alternatives such as cruise missiles . The original cost estimate
7426-559: The original design, including air-, sub-, and ground-launched configurations with both conventional and nuclear armaments. The Tomahawk's manufacturing history has seen several transitions. General Dynamics served as the sole supplier in the 1970s. From 1992 until 1994, McDonnell Douglas was the sole supplier of Tomahawks, producing Block II and Block III versions and remanufacturing many Tomahawks to Block III specifications. In 1994, Hughes Aircraft , having purchased General Dynamics' missile division in 1992, outbid McDonnell Douglas to become
7520-464: The ramjet-powered Tomahawk would still have to fit within a 21-inch (530 mm) diameter and 20-foot (6.1 m) long tube. In October 2015, Raytheon announced the Tomahawk had demonstrated new capabilities in a test launch, using its onboard camera to take a reconnaissance photo and transmit it to fleet headquarters. It then entered a loitering pattern until given new targeting coordinates to strike. By January 2016, Los Alamos National Laboratory
7614-576: The remaining Block III missiles will be retired and demilitarized. Tomahawk Block V have longer range and dynamic targeting with the capability to hit vessels at sea (maritime strike role). Raytheon is recertifying and modernizing the missile, extending its service life by 15 years, and resulting in the new Tomahawk Block V series: In 2020, Los Alamos National Laboratory reported that it would use corn ethanol to produce domestic fuel for Tomahawk missiles, which also does not require harsh acids to manufacture, compared to petroleum-based JP-10. Each missile
7708-481: The satellite to Earth", making them "easy to jam with comparatively little power". In the "early 2000s" the US military rolled out the Selective availability anti-spoofing module (SAASM), along with encrypted military M-code GPS signaling to ensure that the JDAM only accepts signals with correct encryption and rejects all other signals. However, according to one electronic warfare (EW) expert who spoke to RUSI, despite
7802-482: The ship launched- and submarine launched versions of the Tomahawk to be installed on both existing as well as future frigates & submarines. In 2022 plans for acquiring long-range and precision-guided weapon systems for the frigates and submarines of The Royal Netherlands Navy were announced as part of the Strategic Defence Review 2022, Tomahawk was identified. In March 2023, the commander of
7896-517: The sole supplier of Tomahawks. A joint venture between Hughes and Raytheon manufactured the missile from 1995 until Raytheon's acquisition of Hughes in 1997, solidifying their position as the sole supplier. In 2016, the US Department of Defense purchased 149 Tomahawk Block IV missiles for $ 202.3 million. As of 2024 , Raytheon remains the sole manufacturer of non-nuclear, sea-launched Tomahawk variants. The variants and multiple upgrades to
7990-567: The superior accuracy of seeker guidance. Despite their precision, JDAM employment has risks. On 5 December 2001, a JDAM dropped by a B-52 in Afghanistan nearly killed Hamid Karzai while he was leading anti- Taliban forces near Sayd Alim Kalay alongside a US Army Special Forces (SF) team. A large force of Taliban soldiers had engaged the combined force of Karzai's men and their American SF counterparts, nearly overwhelming them. The SF commander requested Close Air Support (CAS) to strike
8084-453: The target area. The guidance data was computed by a mainframe computer which took spy satellite photos and estimated what the terrain would appear like during low level flight. Since this data would not match the real terrain exactly, and since terrain changes seasonally and with changes in light quality, DSMAC would filter out differences between maps and use the remaining similar sections in order to find its location regardless of changes in how
8178-472: The target have significant restrictions on the launch envelope due to the seeker field of view. Some of these systems (such as the Paveway I, II, and III) must be launched so that the target remains in the seeker field of view throughout the weapon trajectory (or for lock-on-after-launch engagements, the weapon must be launched so that the target is in the field of view during the terminal flight). This requires
8272-511: The treaty's deadline of 1 June 1991. On 10 July 2024, a joint statement of the US and Germany was released, announcing the beginning of episodic deployments of long-range fires units with conventional warheads. Deployment will start from 2026, including Typhon missile launchers with SM-6 and Tomahawk missiles. This is considered as a direct response to Russia's President Vladimir Putin 's call to resume production and global deployment of intermediate range missiles, two weeks prior. Putin accused
8366-510: The two-way satellite data link. Firing platforms now have the capability to plan and execute GPS-only missions. Block IV also has an improved anti-jam GPS receiver for enhanced mission performance. Block IV includes Tomahawk Weapons Control System (TTWCS), and Tomahawk Command and Control System (TC2S). On 16 August 2010, the Navy completed the first live test of the Joint Multi-Effects Warhead System (JMEWS),
8460-414: The very limited computer power of the day, DSMAC did not directly evaluate the maps, but instead would compute contrast maps and then combine multiple maps into a buffer, then compare the average of those combined images to determine if it was similar to the data in its small memory system. The data for the flight path was very low resolution in order to free up memory to be used for high resolution data about
8554-507: Was $ 40,000 each for the tail kits; however, after competitive bidding, contracts were signed with McDonnell Douglas (later Boeing ) for delivery at $ 18,000 each. Unit costs, in current-year dollars, have since increased to $ 21,000 in 2004 and $ 27,000 by 2011. To the cost of the tail kit should be added the costs of the Mk80-series iron bomb, the fuze and proximity sensor which bring the overall weapon cost to about $ 30,000. For comparison,
8648-473: Was developed by Israel after the US government under the Clinton administration refused an Israeli request in 2000 to purchase Tomahawk SLCMs because of international Missile Technology Control Regime proliferation rules. As of 12 March 2015 , Poland has expressed interest in purchasing long-range Tomahawk missiles for its future submarines. In July 2024, according to a spealized military source,
8742-975: Was tested in 2022, and were successfully used to sink USS Dubuque (LPD-8) and USS Tarawa (LHA-1) during the RIMPAC 2024 exercise.

8836-418: Was working on a project to turn unburned fuel left over when a Tomahawk reaches its target into an additional explosive force. To do this, the missile's JP-10 fuel is turned into a fuel air explosive to combine with oxygen in the air and burn rapidly. The thermobaric explosion of the burning fuel acts, in effect, as an additional warhead and can even be more powerful than the main warhead itself when there
