Defense Innovation Unit issues contract for unmanned orbital outpost
The Defense Innovation Unit has awarded Sierra Nevada Corporation a contract to build an orbital laboratory that would serve as a kind of unmanned space station, the company announced July 14.
The unmanned orbital outpost will be placed in low Earth orbit to be used for experiments and demonstrations. The autonomous, free flying vehicle will be able to host payloads and support space assembly and manufacturing, microgravity experimentation, logistics, training, testing and evaluations.
Under the contract, Sierra Nevada Corporation will repurpose their Shooting Star transport vehicle into a scalable, autonomous space station that can be used for experiments and demonstrations. The Shooting Star vehicle is a 16-foot attachment to the company's Dream Chaser space plane that was developed for NASA Commercial Resupply Services 2 missions. The vehicle was initially designed to provide extra payload storage and cargo disposal upon re-entry.
“We're excited by the multi-mission nature of Shooting Star,” Fatih Ozmen, SNC's chief executive, said in a statement. “It was originally developed for NASA resupply missions to the International Space Station, and since then we keep identifying new capabilities and solutions it offers to a wide variety of customers.”
The company's press release notes that while the initial orbital outpost will operate in LEO, future orbits could be placed in other orbits, including cislunar.
“The current Shooting Star is already designed with significant capabilities for an orbital outpost and by adding only a few components we are able to meet Department of Defense needs.” added Steve Lindsey, senior vice president of strategy for SNC's space systems. “We are proud to offer our transport vehicle to DoD as a free-flying destination for experimentation and testing, expanding beyond its current payload service capabilities for Dream Chaser cargo missions.”
According to the original DIU solicitation released June 2019, orbital outposts will need to be established in low Earth orbit within 24 months of the award. A DIU spokesperson told C4ISRNET at the time that the “the prototype will explore the military utility of exclusive DoD access to an unmanned orbital platform in order to perform experiments with no risk to human crew or other non-DOD payloads.”

New at the Paris Air Show
Airbus Vahana With urban air mobility a central theme of this year's event, Airbus is showcasing its growing fund of expertise, accumulated partly from the Vahana multirotor. Intended to be the first certified electric, self-piloted, vertical take-off and landing ( e VTOL) passenger aircraft, Vahana flew in the U.S. in January 2018, but did not demonstrate transition to forward flight until May 3 this year. The manufacturer is also developing a second design, the CityAirbus, but will place neither in production. Full artcile: https://aviationweek.com/paris-airshow-2019/new-paris-air-show

Pencils down: Bids are in to replace the US Army’s Bradley fighting vehicle
By: Jen Judson WASHINGTON — The bids are in for a chance to build prototypes for the Army's Optionally Manned Fighting Vehicle that will replace its Bradley Infantry Fighting Vehicle. Among them is a Raytheon and Rheinmetall team putting forward Rheinmetall's Lynx 41 Infantry Fighting Vehicle, and General Dynamics Land Systems, which showcased its Griffin III technology demonstrator equipped with a 50mm cannon a year ago at the Association of the U.S. Army's annual exposition. It is currently unknown if any other teams submitted bids by the service's set deadline of Oct. 1. None have come forward publicly despite rumors of a dark horse or two. Absent from the usual brood of combat vehicle manufacturers is BAE Systems. Defense News broke the news earlier this year that the company wouldn't compete in the OMFV competition. Textron has joined the Raytheon and Rheinmetall team with plans to, if chosen to build the new vehicle, build Lynx here in the United States at its Slidell, Louisiana, manufacturing facility. Raytheon and Rheinmetall announced a joint venture Oct. 1 — calling it Raytheon Rheinmetall Land Systems LLC — to pursue the OMFV competition. “General Dynamics Land Systems submitted our OMFV proposal and bid sample to the US Army on 27 September. GD's bid sample was purpose built to address the desired system lethality, survivability and mobility as substantiation of our response to the Army's request for proposal,” the company said in a statement sent to Defense News. The company did not provide details on the submission. GDLS did note, however, that it is proposing a “purpose built vehicle” using technologies from other platforms and “years of investment in advanced capabilities to include a 50mm cannon,” according to the statement. The Army released its request for proposals in March opening a competition to build prototypes. The service plans to choose from the pool of bidders up to two teams to build 14 prototypes each. The service will choose a winner that will start replacing Bradleys in 2026 that is designed to better operate in future environments that would allow soldiers to maneuver to a position of advantage and “to engage in close combat and deliver decisive lethality during the execution of the combined arms maneuver,” according to an Army statement issued along with the RFP release. Some of the threshold requirements for OMFV are a 30mm cannon and a second-generation, forward-looking infrared system, or FLIR. Objective requirements are a 50mm cannon and a third-generation FLIR. Brig. Gen. Ross Coffman, who is in charge of Next-Generation Combat Vehicle (NGCV) modernization efforts, said at the Defense News Conference in September that he is confident the requirements set for OMFV are right and had no plans to change them. The selected prototypes will go through “rigorous” operational testing and soldier assessments. The Army plans to downselect to one vehicle for low-rate initial production following the assessments and testing. https://www.defensenews.com/land/2019/10/01/pencils-down-bids-are-in-for-armys-bradley-fighting-vehicle-replacement
