Pratt & Whitney Awarded Contract for F135 Engine Modernization Study
EAST HARTFORD, Conn. — Pratt & Whitney, a division of Raytheon Technologies Corp., has been awarded a $1.5M contract to conduct an F135 modernization study and operational assessment by the F-35 Joint Program Office to determine specific propulsion system growth requirements for Block 4.2 F-35 aircraft and beyond, the company said in an Oct. 20 release. The study is expected to conclude in March 2021.
“This award is a significant milestone for the program and the warfighter, as we look to ensure the F135 propulsion system continues to provide the foundation for all air vehicle capability requirements over the full lifecycle of the F-35,” said Matthew Bromberg, president, Pratt & Whitney Military Engines. “As we look to the future, growth in aircraft capability must be met with matched propulsion modernization. Fortunately, the F135 has ample design margin to support agile and affordable upgrades that will enable all F-35 operators to keep pace with evolving threat environments.”
Under this award, Pratt & Whitney will assess F135 engine enhancements required to support future F-35 weapon system capability requirements across all F-35 variants beginning with Block 4.2 aircraft. The scope of the assessment focuses on enhancements addressing improvements to up and away thrust, powered lift thrust, power and thermal management capacity, and fuel burn reduction.
Designed with the knowledge that operational environments will evolve and threats will advance, the F135 is postured to meet future F-35 capability requirements. Its modular design and advanced digital architecture allow for the agile development and spiral insertion of both hardware and software upgrades. As part of the study, Pratt & Whitney's GATORWORKS organization will complete the conceptual design and analysis of multiple F135 Engine Enhancement Package (EEP) growth options with phased insertion plans.
Leveraging significant U.S. Government and Pratt & Whitney investment in next generation adaptive propulsion technologies, Pratt & Whitney's EEP approach offers low risk, variant-common upgrade options for the F135 that provide increased performance aligned with the program's continuous capability development and delivery strategy and serve as a critical enabler for future capability growth of the F-35 weapon system.
The combat-proven F135 is the most advanced operational fighter engine in the world, delivering 26% more thrust, 116% more powered lift, and more than a 300% increase in power and thermal management over 4th generation fighter engines – all with a demonstrated mission capability rate of greater than 94%.
“Built upon decades of combat propulsion experience, the F135 provides the warfighter with a critical technological advantage over adversaries at an unparalleled value to the taxpayer,” said Bromberg. “With more than 40,000 pounds of thrust, unmatched low-observable signature, world-class thermal management, and innovative engine control system, the F135 is a critical enabler of the F-35 weapons system and of operations conducted in advanced threat environments – a core element of the National Defense Strategy.”

Le français Parrot retenu par l’armée américaine pour construire des drones de reconnaissance
Sérieusement concurrencée par DJI sur le domaine des drones grand public, la marque française Parrot élargit son horizon. Elle travaille de plus en plus sur des engins destinés aux professionnels et pourrait bientôt décrocher un contrat de grande ampleur. La firme a en effet été retenue (avec cinq autres sociétés) par le département de la Défense des États-Unis pour un appel d'offres visant à développer et à prototyper une nouvelle génération de drones compacts, de courte portée et dédiée à la surveillance (« Short Range Reconnaissance drone » ou SRR). Il semblerait donc que la méfiance envers les acteurs chinois (majoritaires) du secteur fasse le bonheur des autres. Henri Seydoux, président et PDG de Parrot, a réagit à l'annonce de la sélection : « Parrot est fier d'avoir été sélectionné par l'U.S. Army pour travailler sur ce projet hautement stratégique [...] Nous comprenons parfaitement combien un drone ultra-compact, à l'instar de la plateforme de drone ANAFI, possède les atouts pour devenir un élément central de la défense. Nous sommes impatients de mettre à profit l'excellence de notre R&D pour répondre aux plus hautes exigences de l'U.S. Army afin d'intégrer l'efficacité offerte par les drones dans leurs opérations et d'accompagner la plus importante force armée et de défense au monde. » Ledit programme a en effet alloué 11 millions de dollars de dollars à ces six acteurs afin qu'il puisse rapidement mettre au point un drone capable d'être déployé rapidement sur le terrain par les soldats. Il permettra ainsi de disposer d'un meilleur champ de vision et d'une « compréhension immédiate et élargie » de l'environnement dans lequel ils évoluent. Évidemment, l'armée a défini plusieurs objectifs que l'appareil doit remplir pour être sélectionné. Il devra notamment bénéficier d'un temps de vol de 30 minutes et d'une portée allant jusqu'à 3 kilomètres. Son poids ne pourra excéder 1,3 kg/ Il faudra qu'il soit opérationnel en moins de 2 minutes et doit pouvoir être transporté dans les sacs à dos standards utilisés par les soldats. Rien qui ne paraisse impossible à réaliser pour la firme, qui joue très gros sur ce marché. https://www.journaldugeek.com/2019/05/30/le-francais-parrot-retenu-par-larmee-americaine-pour-construire-des-drones-de-reconnaissance/

Danish radars on French aircraft carrier
Aarhus, March 25, 2020 - The French aircraft carrier Charles de Gaulle, which visits Danish waters this week, is equipped with two radar systems provided by Terma. The SCANTER 6000 radar systems are used for surveillance, search and navigation at sea - and in the air to guide helicopters on landing. In recent years, Terma has provided radar systems to a number of vessels in the French Navy through a collaboration with the French defense company Naval Group, which among others has built Charles de Gaulle. The French carrier has a fixed crew of about 2,000 men and weighs about 40,500 tonnes. It is accompanied by several escort ships and will be accompanied by the Danish frigate Niels Juel of the Iver Huitfeldt class during its visit. Through its long-standing partnership with the Danish Navy, Terma has provided radar systems, self-defense systems and command-control systems to all of the Navy's large naval vessels, including the three frigates, which also make use of the same radar type SCANTER 6000 as Charles de Gaulle. Terma's radar systems are used by many countries around the world on many different types of navy and coastguard vessels due to their ability to see small targets such as fast crafts and jet skis at long range and in all kinds of weather. Terma's radars are therefore also used for coastal and traffic surveillance e.g. at VTS Storebælt. About us The Denmark based high-tech Terma Group develops products and systems for defense and non-defense security applications; including command and control systems, radar systems, self-protection systems for aircraft, space technology, and aerostructures for the aircraft industry.
