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.

The Pentagon’s AI lead needs a cloud integrator
By: Andrew Eversden The Pentagon's lead artificial intelligence office is seeking a cloud integrator to help launch its hybrid, multi-cloud environment. The Defense Information Systems Agency released two source solicitations Nov. 22 on behalf of the Defense Department's Joint Artificial Intelligence Center, seeking small and large businesses that can provide JAIC with system engineering and system integration services during the deployment and maintenance of the hybrid, multi-cloud environment. The cloud environment is an important piece of JAIC's Joint Common Foundation, an enterprisewide AI platform under development by JAIC. The foundation will provided tools, shared data, frameworks and computing capability to components across the Pentagon. JAIC is responsible for accelerating, scaling and synchronizing AI efforts across the Pentagon. “The concept is to provide AI project teams with a set of established processes, tools and delivery methodologies that can facilitate the delivery of mission capabilities and integration into operational mission capabilities,” the solicitation read. Any company chosen should expect to work within Microsoft's cloud environment, as the tech giant recently won the Pentagon's enterprise cloud contract known as the Joint Enterprise Defense Infrastructure, or JEDI. Lt. Gen. Jack Shanahan, head of the JAIC, has continuously asserted that JAIC would be further along in its cloud capabilities if it had an enterprise cloud. The JEDI effort has been delayed by more than six months due to several protests. According to the solicitation, the request for quote is expected to be released in the late second quarter of fiscal 2020, with an award in the late fourth quarter of the fiscal year. https://www.federaltimes.com/acquisition/2019/11/27/the-pentagons-ai-lead-needs-a-cloud-integrator/
