U.S. Army Awards Lockheed Martin Contract To Develop Sentinel A4 Radar

SYRACUSE, N.Y., Sept. 27, 2019 /PRNewswire/ -- Lockheed Martin (NYSE: LMT) has been awarded a $281 million contract by the United States Army to develop the Sentinel A4 radar system.

Sentinel A4 is a high-performance modification of the Sentinel A3 (AN/MPQ-64A3) air and missile defense radar that will provide updates to improve the existing Sentinel capability against cruise missiles, unmanned aerial systems, rotary wing and fixed wing threats.

The new Sentinel A4 radar will provide improved surveillance, detection, and classification capabilities against current and emerging aerial threats in order to protect Army maneuver formations and high value static assets to include: command and control nodes, tactical assembly areas and geo-political centers. This needed capability will help protect our warfighters for the next 40 years.

"By leveraging our open scalable radar architecture and production efforts, we believe we provide the lowest risk and best value solution for the U.S. Army that will help protect our warfighters for years to come," said Dr. Rob Smith, vice president and general manager for Lockheed Martin's Radar and Sensor Systems. "We have fielded numerous tactical Gallium Nitride (GaN) based radars beginning with the delivery of the TPS-77 Multi Role Radar to Latvia in 2018 and we are under contract with the Army to insert GaN into the Q-53 system."

    Singapore Airshow 2020: IAI takes aim at Singapore's next-gen UAV requirement with Heron MKII

    Israel Aerospace Industries (IAI) has taken the opportunity at Singapore Airshow 2020 to showcase its Heron MKII medium altitude long endurance unmanned aerial vehicle (MALE UAV) to the public for the first time, and has declared its intention to pitch the new air vehicle at a Singaporean requirement for next-generation UAVs. Moshe Levy, IAI's executive vice president and general manager of its Military Aircraft Group, told Jane's that the Heron MKII builds on the experience gained from developing the incumbent Heron 1 UAV and will offer improved performance via several airframe design and propulsion updates, although its general physical characteristics remain unchanged with an overall length and wingspan of 8.5 m and 16.6 m, respectively. Newly incorporated enhancements include a widened fuselage pod designed to accommodate a greater number of sensors and/or more powerful mission systems as well as a new propulsion configuration comprising the fully certified Rotax 915 iS 1,352 cc turbocharged four-stroke engine, which has a time before overhaul (TBO) rating of 1,200 hours. It also produces up to 135 hp at maximum continuous power and is coupled to a three-bladed variable-pitch pusher propeller. IAI claims that the new engine will provide the Heron MKII with a 50% improvement on the rate of climb over that of the Heron 1, as well as a 16.6% boost over the current maximum speed of 120 kt to 140 kt, although it retains a comparable loiter speed profile of between 60 and 80 kt. The new air vehicle's maximum take-off weight (MTOW) has also increased to 1,350 kg with a corresponding uptick in payload capacity to 470 kg. In contrast, the Heron 1 has a MTOW of about 1,200 kg and is powered by a 1,211 cc four-stroke Rotax 914 F engine that can develop up to 100 hp at maximum continuous power, which in turn drives a two-bladed pusher propeller. https://www.janes.com/article/94282/singapore-airshow-2020-iai-takes-aim-at-singapore-s-next-gen-uav-requirement-with-heron-mkii?from_rss=1

    Le Japon va acquérir 105 avions de combat américains F-35

    Le Japon va acheter 105 avions de combat américains F-35 supplémentaires, a annoncé lundi le président américain Donald Trump à l'issue d'un sommet avec le premier ministre japonais Shinzo Abe. « Les États-Unis soutiennent les efforts du Japon pour améliorer ses capacités de défense, et ces derniers mois nous leur avons envoyé une grande quantité d'équipements militaires », a déclaré M. Trump lors d'une conférence de presse, annonçant « l'intention du Japon d'acheter 105 F-35 neufs ». Le Japon, qui avait déjà annoncé fin 2011 l'achat de 42 F-35, est avec cette nouvelle commande le premier client international pour cet avion de combat de cinquième génération. En réalité, l'archipel s'était déjà engagé en décembre à cette acquisition, portant à 147 le nombre de ces chasseurs furtifs en sa possession, selon un communiqué du constructeur aéronautique américain Lockheed Martin publié à l'époque. Le gouvernement de Shinzo Abe, qui a annoncé en décembre un budget record pour la défense, a accru ses importations d'équipements militaires américains sous la pression de Donald Trump. Le but est de contrer la menace militaire de la Chine, mais aussi de réduire le déséquilibre commercial avec les États-Unis, régulièrement dénoncé par le président américain. Lancé au début des années 1990, le F-35 est produit par Lockheed Martin, et ses moteurs par un autre américain, Pratt et Whitney. Selon les derniers chiffres, 390 F-35 ont été livrés dans le monde. C'est le plus cher des programmes d'armement de l'histoire militaire américaine, avec un coût estimé au total à près de 400 milliards de dollars pour l'armée américaine, pour un objectif de près de 2500 appareils à produire dans les décennies à venir. https://www.lapresse.ca/affaires/201905/27/01-5227679-le-japon-va-acquerir-105-avions-de-combat-americains-f-35.php
