rogue0 Posted October 20, 2017 Author Share Posted October 20, 2017 Dépassements de coûts sur le programme SDB-2 alias GBU-53. Ce qui est nouveau, c'est que le constructeur doit désormais payer tout nouveau dérapage de sa poche (40M$ pour l'instant). Cela ne remet pas en cause le programme. Les chasseurs furtifs US en sont très dépendants pour mener des frappes air-sol en emport interne (configuration furtive). Cela leur permet de traiter des cibles mobiles (pickup toyota...), ou plus de 2 cibles par sortie (jusqu'à 8 SDB-2)https://www.bloomberg.com/news/articles/2017-10-18/raytheon-s-smart-bomb-delays-may-extract-a-cost-for-the-company http://www.thedrive.com/the-war-zone/15257/usaf-and-raytheon-say-cost-overruns-wont-slow-delivery-of-vital-new-bomb 1 Link to comment Share on other sites More sharing options...

J'en profite pour signaler qu'il y a en ce moment un hors-série de DSI sur "contrer le déni d'accès", qui parle des différentes munitions permettant de frapper les systèmes mobiles longue portée. Il y a même un article de @PolluxDeltaSeven sur les munitions saturantes (Smart Glider, SDB et autres Spice 250).

hadriel Posted October 23, 2017 Share Posted October 23, 2017 (edited) Quelques extraits pertinents de l'appel d'offre finlandais pour un nouveau chasseur: Citation Missile and bomb sensor technology development increas- es their multi-role usability. It is likely that the weapons used against sea- and land-based targets and those used in the sup- pression of enemy air defences (SEAD) can, at least partly, be phased out over the next 10–15 years. Precision-guided bombs will retain their status as effective and inexpensive basic weapons against hard and soft surface targets as well as against hardened bunkers and underground targets. Their accuracy in different weather and lighting con- ditions can be improved by utilising systems that combine sat- ellite and inertial positioning as well as pattern/shape recogni- tion and laser homing. Laser-guided bombs can also be used against moving targets Glide bombs are bombs that incorporate flight control sur- faces for added distance. Their range is approximately 20–100 km, which is considered to be sufficient to engage targets at distances far-enough away to evade the target area’s anti-air- craft systems (stand-off), thereby allowing air-to-ground mis- siles to be replaced with glide bombs. It is necessary to keep improving the weapons’ multi-role capability and reduce the assortment of different role-specific weapons; this is particu- larly important from the perspective of stealth aircraft multi- role capabilities and the optimum utilisation of their internal payloads. Even as glide bombs are increasingly becoming ubiquitous, alongside them multi-role short-range missiles such as the MBDA Brimstone 2 and the Lockheed Martin Joint Air-to- Ground Missile (JAGM) are being developed. Short-range missiles are eminently suitable for destroying single, station- ary and mobile, land- and sea-based targets from up to 10–20 km. Because they are so small, one wing pylon can fit several of them. Short-range missiles can also be used in UAVs. Cruise missiles are unmanned missiles furnished with jet engines, flying most of their pre-planned route at a constant airspeed. They are used against the adversary’s well defended and critical targets which are hard to reach by other means and are often located deep inside the adversary’s territory. Anti-ship missiles are cruise missile type weapons designed to defeat surface targets. The central objectives in long-range missile development are improvements in their multi-role us- ability and improvements in air defence missile performance. Technology solutions that aid penetrability through air de- fences are, among other things, stealth technology and the use of ramjets. Examples of these include the JASSM missile, soon to be introduced in the Finnish Air Force, and the Brahmos missile which can reach Mach 3, a weapon of Russian-Indian design Citation Ballistic missiles, cruise missiles and stand-off weapons such as glide bombs as well as stealth targets are difficult to shoot down because of their low observability, trajectory or speed. Modern smart weapons make it possible for aircraft to engage targets in all conditions, both at altitude and far away from the target.

hadriel Posted October 25, 2017 Share Posted October 25, 2017 L'USAF veut une liaison de données et un autodirecteur RF passif pour le JASSM-ER: http://aviationweek.com/awindefense/more-fighters-bombers-receiving-jassm-er-cruise-missile Citation In terms of future capability upgrades for the missile, the Air Force highlights some plans in its fiscal 2018 budget. Those include an anti-radiation homing system for targeting radio frequency emitters like radars and communications sites. The service also wants a weapon data link for passing updated targeting information in mid-flight, which would allow Jassm-ER to strike relocatable or roaming land and maritime targets. Under a recent contract with the Air Force, Lockheed will also develop an improved wing that adds additional range and performance. The missile is accurate to within 3 m of a target using its onboard imaging infrared seeker, or within 13 m when only guided by GPS-aided inertial navigation..... In terms of other platforms for Lrasm and Jassm-ER, the Air Force’s Lockheed F-35A and the Navy’s F-35C seem like obvious candidates. But Jackson says the AGM-158-series cruise missile did not make the shortlist of weapons being integrated under the F-35 Block 4 follow-on modernization program. Instead, it will be considered as part of Block 5, a future upgrade program that could materialize in the mid-2020s. Link to comment Share on other sites More sharing options...

Edit: l'article complet trouvé sur F16.net: Citation U.S. Air Force JASSM-ER Rolling Out To New Fighters, Bombers James Drew | Aviation Week & Space Technology As technologies for long-range air defense improve and proliferate, the U.S. military has long sought a counter—missile that can strike land-based targets from hundreds of miles away. In the mid-1990s, the U.S. Air Force and Navy partnered to develop the AGM-158 Joint Air-to-Surface Standoff Missile (JASSM), but it was not deployed until 2009 and had limited range due to its Teledyne J402 turbojet engine. Now the Pentagon believes it has a more effective weapon in the JASSM extended-range version (JASSM-ER), powered by the Williams International F107 turbofan and with a range exceeding 500 nm (926 km). It is being integrated on Air Force fighters and bombers, including the Lockheed Martin F-16, Boeing F-15E and B-52 and Northrop Grumman B-2. These aircraft can already carry the legacy version of JASSM but require additional integration to take full advantage of the AGM-158B’s superior range and performance. Once equipped, they will be capable of destroying high-value targets over an area of 785,398 nm². KILLER CRUISE MISSILE Air Force upgrade path for JASSM-ER includes a new wing, anti-radiation homing and weapon data link Navy has no immediate plans to adopt JASSM-ER for Super Hornet along with LRASM Integration with F-35A/C not expected until Block 5 upgrade in the mid/late-2020s Despite partnering with the Air Force in the early stages of the program, the Navy has no immediate plans to adopt the land-attack cruise missile for its strike fighters. The service has instead developed a ship-killing variant for its Boeing F/A-18E/F Super Hornet called the AGM-158C Long-Range Anti-Ship Missile (LRASM). Operators of Lockheed’s F-35A and carrier-based F-35C will also be watching the early performance of the JASSM-ER. The weapon did not make the cut for the F-35’s Block 4 follow-on modernization program, and it will instead be considered for the next iteration, Block 5, in the mid/late-2020s. (emphasis mine) Alan Jackson, director of strike systems at Lockheed’s missiles and fire control division, confirms that the JASSM-ER has been integrated with U.S. Air Combat Command’s fleet of F-15E Strike Eagles. Coming up next will be integration with the F-16 and B-52H, including external and internal carriage. “We’re already on the F-15E, and that was using the Universal Armament Interface,” Jackson tells Aviation Week. “F-16 integration is going on right now.” Air Force budget documents state that the missile will be integrated with the F-16C/D Block 40/42/50/52-series fighters and a contract for nonrecurring (one-off) engineering was awarded in March. There is also some work left for the Strike Eagle, specifically integrating the F-15E’s Northrop Litening Advanced Targeting Pod. For bombers, the B-52 can carry up to 12 JASSM-ERs on its wings and with the new 1760 Internal Weapons Bay Upgrade, another eight internally. The only other aircraft that can carry more JASSM cruise missiles than the B-52H is the B-1B, which accommodates 24 missiles inside its internal weapons bays. Brig. Gen. Michael Schmidt, the Air Force’s program executive officer for fighters and bombers, confirmed during a recent interview that the B-2 Spirit bombers of Whiteman AFB, Missouri, are also slated to receive JASSM-ER. The B-2’s primary mission is nuclear deterrence, but the JASSM-ER provides a long-range, conventional option for striking high-value targets from outside the range of counterstealth radars and interceptors. The B-2 will require some changes, and development should start by mid-2018, Air Force documents state. In terms of capability upgrades for the missile, the service highlights some plans in its fiscal 2018 budget proposal. It includes funding for studies of an anti-radiation homing system for targeting radio frequency emitters such as radars and communications sites. The service wants a weapons data link for passing updated targeting information to the missile midflight, enabling JASSM-ER to hit relocatable or roaming land and maritime targets. Under a recent government contract, Lockheed is developing an improved wing that will add greater range and performance. The missile is accurate to within 3 m (10 ft.) of a target using the onboard imaging infrared seeker, or within 13 m when only guided by GPS-aided inertial navigation. The continued rollout of the JASSM-ER comes as flight testing of the anti-ship derivative begins on the B-1B for fielding in 2018 and the F/A-18E/F in 2019. Jackson says LRASM retains all the features, targeting capabilities and low-observable characteristics of the JASSM-ER but adds another passive sensor produced by BAE Systems. He would not say what type of sensor it is or what part of the electromagnetic spectrum it operates in, but it is probably a semi-active radar homing device. Once LRASM is introduced, the B-1B and the Navy’s Super Hornet will be capable of destroying land targets as well as moving vessels at sea from significant standoff ranges. Jackson says the Navy has no plans to adopt the less expensive JASSM-ER for striking land targets, even though it would be quicker, cheaper and easier to integrate LRASM and JASSM-ER at the same time rather than separately. “That would be an attractive option, but for now the Navy wants to remain focused on just getting LRASM out the door,” Jackson says. “It’s a low-risk, low-cost and relatively easy way to do the integration if you piggyback the two at the same, but nevertheless, if or when that happens, that will be a separate integration effort.” JASSM and LRASM are produced by Lockheed in Troy, Alabama. The Air Force intends to procure JASSM cruise missiles at a rate of 360 per year. The missile is a major international sales opportunity for Lockheed, as it has already been adopted by Australia, Poland and Finland. Other foreign sales could materialize, particularly for trusted operators of the F-16, once integrated. Australia’s Super Hornets would be obvious candidates for the JASSM-ER and potentially LRASM.

hadriel Posted January 9, 2018 Share Posted January 9, 2018 (edited) Les Russes développent une munition planante équivalente au JSOW pour engager les véhicules à distance de sécurité: https://www.rt.com/news/415279-russia-militray-drel-bomb/ Citation ussia’s military is about to adopt a state-of-the-art aerial bomb, called ‘Drel’, or drill, which can be dropped by a bomber without entering an enemy’s airspace, due to the weapon’s ability to glide for dozens of kilometers. The head of Russian munitions developer Techmash, Vladimir Lepin, described ‘Drel’ as a “gliding bomb cartridge with a caliber of 500 kilograms, equipment with self-targeting combat elements.” [...] Drel’ is planned to be put in service by the Russian Airspace Forces after the successful conclusion of the trails in 2018, he added. Earlier, Techmash said that their bomb is capable of gliding dozens of kilometers and hit armored vehicles, ground-based radars, command posts and power units of anti-aircraft missile systems with high precision. ‘Drel’ is a cluster ammunition, which ways weighs 540 kilograms and includes 15 self-targeting warheads.

rogue0 Posted January 26, 2018 Author Share Posted January 26, 2018 (edited) Le 07/12/2008 à 15:51, PolluxDeltaSeven a dit : Les USA bossent sur une version améliorée du Harm, la AARGM, qui devait initialement entrer dans les soutes du F-117 (depuis retiré du service). A terme, il y a fort à parier que le successeur du HARM et du AARGM aura les dimensions requises pour rentrer dans la soute d'un F-22 ou d'un F-35.(...) D'autres estiment qu'il sera possible de développer un AARGM avec une voilure réduite à son stricte minimum et une longueur diminuée. Le missile resterait plus encombrant que l'AMRAAM, mais conserverait toutes les performances du AARGM (ce qu'une cellule basée sur l'AMRAAM ne permet pas, en raison de la petite taille de son antenne). Réponse 9 ans après. Tu as gagné le gros lot. L'USAF vient de signer un contrat pour le développement d'un missile antiradar longue portée, le AARGM-ER. Le but était d'avoir toutes les fonctionnalités de l'AARGM, mais avec une portée accrue (+50% minimum? pour contrer les SAM longue portée de déni d'accès), et qui rentre dans la soute du JSF (sauf le -B) Voici le premier concept. http://www.janes.com/article/71285/orbital-atk-firms-up-aargm-er-design-concept http://www.thedrive.com/the-war-zone/17947/navy-orders-development-of-new-air-defense-blasting-missile-that-will-fit-inside-f-35 En gros, Orbital ATK n'a pas réinventé la roue, ils ont pris les composants du AARGM, et les ont emballé dans un corps de missile compact, à fuselage portant, et avec un moteur amélioré (double impulsion). Le 10/10/2017 à 23:57, hadriel a dit : - Globalement j'ai pas l'impression que la munition réponde très bien aux futures problématiques de déni d'accès face à des S-400 bien employés. Certes ça permet de frapper les cibles à la périphérie et pas mal à l'intérieur de la bulle AA, mais ça ne permet ni d'aller neutraliser la batterie elle-même, ni probablement d'aller frapper des objectifs solidement défendus par une défense de point. Je pense qu'un système non planant aurait plus de sens, même si il est plus lourd par munition. Typiquement un engin avec la même charge militaire, un gros moteur à poudre et de la manœuvrabilité tout au cours du vol et surtout en phase terminale serait plus efficace je pense. C'est un peu le concept des US avec leur AARGM-ER, un missile balistique avec un peu de portance qui va à 100-150km. Apparemment, il n'est pas forcément ballistique (sauf éventuellement en limite de portée, et si le SAM a été géolocalisé) Edited January 26, 2018 by rogue0 1 Link to comment Share on other sites More sharing options...

rogue0 Posted February 28, 2018 Author Share Posted February 28, 2018 L'USAF va acquérir des bombes en fonte (cast iron). Les autres caractéristiques (forme, poids, centre de gravité) seraient identiques aux Mk8x actuelles.http://www.thedrive.com/the-war-zone/18829/usaf-getting-cast-iron-ductile-bomb-cluster-munition-replacement-despite-policy-change Quel est l'intérêt? ça projetterait plus de fragments (surtout si elle est prédécoupée). Combiné à un amorçage à hauteur réglable par le pilote (VT), ça permettrait d'ajuster la taille de la zone de dispersion des fragments. Et cela permettrait d'assurer (en partie) la mission des bombes à sous-munition (cluster bomb). Comme les fragments sont inertes* , ces munitions respecteraient le traité sur les sous-munitions (non ratifié par les USA, qu'ils ont abandonné récemment)... * donc 0% de déminage à faire après-guerre On en parlait sur le fil des lance-roquettes. 1 Link to comment Share on other sites More sharing options...
