  Army drops request for proposals to build next-gen combat vehicle prototypes

  By: Jen Judson WASHINGTON — The U.S. Army on Friday issued a request for proposals to competitively build next-generation combat vehicle prototypes. The RFP opens up competition for industry to provide optionally manned fighting vehicle prototype designs. From that pool, the Army will choose — in the second quarter of fiscal 2020 — up to two teams to build 14 prototypes. The OMFV is intended to replace the Bradley Fighting Vehicle starting in 2026 and 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 combined arms maneuver,” an Army statement reads. 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. “The OMFV must exceed current capabilities while overmatching similar threat class systems,” Brig. Gen. Ross Coffman, the director for the Next-Generation Combat Vehicle Cross-Functional Team, said in the statement. “It must be optimized for dense urban areas while also defeating pacing threats on rural terrain.” The NGCV CFT is part of a new four-star command, Army Futures Command, that is designed to modernize the force. NGCV is the second-highest modernization priority for the Army just behind long-range precision fires. After working with industry through a multitude of engagements and testing several draft RFPs with ambitious requirements, Coffman believes the Army has both the threshold requirements for the vehicle as well as the right objective requirements as the service heads toward the release of the final RFP. “We put out a very aggressive draft RFP,” Coffman told reporters March 27 at the Association of the U.S. Army's Global Force Symposium, because the CFT knew it was not obtainable in its entirety. The draft RFP was meant to stretch goals and objectives and to inspire feedback to ultimately write requirements that are attainable, Coffman explained. The Army's current approach to enter into a rapid prototyping effort truncates what could be a two- or three-year technology-maturation and risk-reduction phase, Maj. Gen. Brian Cummings, the program executive officer for Ground Combat Systems, noted in the statement. “It is about being able to prototype and field required capabilities on an accelerated schedule to get capability into soldiers' hands quickly,” he said. The Army's acquisition chief, Bruce Jette, approved a rapid prototyping approach for the OMFV in September 2018, which requires a prototype demonstration in an operational environment within five years, according to the statement. The 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. Several companies have come forward either with clear plans of what they would like to offer or declaring they will participate in the competition. German company Rheinmetall announced last fall that it would team up with Raytheon to provide its new Lynx combat vehicle. It's also possible its Puma vehicle, which is co-manufactured with German defense firm Krauss-Maffei Wegmann, could be submitted. BAE Systems showed what it could do with a CV90 vehicle at the Association of the U.S. Army's annual show in the fall, and General Dynamics European Land Systems turned heads at AUSA with a Griffin III technology demonstrator equipped with a 50mm cannon. https://www.defensenews.com/land/2019/03/29/armys-request-for-proposals-to-build-next-gen-combat-vehicle-prototypes-drops

  Germany officially knocks F-35 out of competition to replace Tornado

  By: Sebastian Sprenger COLOGNE, Germany ― Germany's Ministry of Defence has officially ruled out the F-35 joint strike fighter as a choice to replace its aging Tornado fleet, Defense News has learned. An official from the ministry confirmed that the F-35 is not a finalist in the competition, which seeks a replacement for the 90-jet fleet. The news was first reported by German site AugenGeradeaus. The move is not altogether surprising. Berlin for some time has officially favored an upgraded version of the fourth-generation Eurofighter Typhoon, built by a consortium of Airbus, Leonardo and BAE Systems, as the Tornado replacement. The main argument is to keep European companies involved in building combat aircraft and, perhaps even more importantly, staying clear of disturbing Franco-German momentum in armaments cooperation. However, the decision leaves open the question of certification for nuclear weapons. The Typhoon is not certified to carry the American-made nuclear bombs that Germany, as part of its strategic posture, is supposed to be able to carry on its jets. Competing against the Typhoon is Boeing's F/A-18E/F Super Hornet. Before the German MoD confirmed that the F-35 was officially out of the running, Reuters on Thursday reported that the ministry was considering splitting the buy between the Typhoon and either the F-35 or Super Hornet. Ordering both the Typhoon and an American aircraft would make it easier to continue carrying out the NATO nuclear mission, while also lending support to the European industrial base. However, it could complicate logistics, adding more expense and forcing the German air force to maintain two supply chains. It is worth noting that despite complaints about the cost of keeping the ageing Tornados flying, keeping around a certain number of them always has been considered a painful, but not impossible, proposition among some defense experts. That is especially the case for the nuclear mission. “There does not have to be a nuclear Tornado replacement,” Karl-Heinz Kamp, president of the Federal Academy for Security Policy, a government think tank, told Defense News last August. He noted that any German government is acutely averse to the publicity surrounding Berlin's would-be atomic bombers. “That's why they will keep flying the Tornados, despite the price tag and despite having asked about a Eurofighter nuclear certification in Washington,” Kamp predicted at the time. German defense officials on Thursday evening stressed that no decisions had been made besides reducing the playing field to the FA-18 and the Eurofighter Typhoon. The Defense Ministry will request additional information from the respective manufacturers, Boeing and Airbus, on the issues of operations, economic viability and timing, these officials said. Germany's decision appears to have come at the surprise of F-35 manufacturer Lockheed Martin, which was not told by the ministry of the imminent announcement. “We have not been officially notified of a decision on Germany's future fighter,” Lockheed spokesman Mike Friedman said in an emailed response to a query. “The F-35 delivers unmatched value as the most capable and lowest life-cycle cost aircraft, while delivering the strongest long-term industrial and economic opportunities compared to any fighter on the market. As the foundation of NATO's next generation of air power, the F-35 is the most advanced aircraft in the world today, and includes Electronic Attack capabilities well beyond any specialized fourth generation aircraft.” Valerie Insinna in Washington contributed to this report. https://www.defensenews.com/global/europe/2019/01/31/germany-officially-knocks-f-35-out-of-competition-to-replace-tornado/

  Coulson’s CU-47 is ready for the fire fight

  Posted on May 22, 2020 by Howard Slutsken Leveraging its experience with fixed-wing air tankers, Coulson Aviation has unveiled its latest aerial firefighting conversion, based on the Boeing CH-47D Chinook heavy-lift helicopter. In early March, the first Coulson-Unical CU-47 was flown from the company's Port Alberni, B.C., base to the Aerial Firefighting North American 2020 conference in Sacramento, Calif. Featuring a 3,000 gallon roll-on/roll-off internal tank and an advanced Garmin avionics suite, up to 12 CH-47Ds will be converted into next-generation heli-tankers, in a partnership with Unical Aviation that was announced a year ago. “Unical provides us with the aircraft and a vast supply of parts,” explained Britt Coulson, president and COO, in an interview with Skies. “They bought the entire Canadian Forces CH-47 parts inventory and were the largest purchaser of CH-47Ds from the U.S. Army.” The twin-rotor Chinook is well known for its speed, size and payload. While the helicopter is often deployed on fire attack missions carrying a water bucket as an external load, Coulson wanted to give the CU-47 more flexibility and capability. The company's engineers had already developed a 4,000 gallon Retardant Aerial Delivery System RADS-XXL for its Lockheed C-130 Hercules tanker conversions, and that tank was shrunk to create a 3,000 gallon RADS-L for the CH-47D conversion. “It's the same overall design as the C-130. It shares most of the same hydraulic components, the same doors and the same design of a roll-in, roll-out tank,” said Coulson. Other CH-47 internal tank systems utilize the small hook well in the centre of the helicopter as the water and retardant delivery port, but according to Coulson, that has its limitations. “The other tank designs are plagued with flow rate issues, which means they don't pack enough punch to really get through [forest] canopies or drop in heavy timber – the hook well opening just isn't big enough. “The lower the flow rate you have out of your tank, the slower and lower you have to fly. The problem with a big helicopter like a Chinook is if you fly too slow and low, your downwash is going to negatively affect the ground fire conditions and your drop is going to be ineffective.” To increase and optimize the flow rate for the RADS-L, the belly of the CH-47D was modified by cutting the helicopter's lower skin and adding structure below the floor to accommodate the tank installation and a pair of drop doors, controlled by the pilots through a state-of-the-art touchscreen controller. From the same touch panel, the pilots also control the CU-47's newly-developed retractable snorkel system to refill the RADS-L tank from water sources close to a fire's location. Installed internally, the snorkel head sits flush with the belly when retracted, so that with no additional external drag, the helicopter can maintain its fast 140-knot cruise speed. In a hover, the snorkel takes just four seconds to deploy and six seconds to retract, and the pilots and flight engineer can monitor the system's operation via a high-definition belly-mounted camera feed, displayed on the touchscreen controller. “The snorkel system has exceeded our expectations and we're filling the entire tank in under two minutes,” said Coulson. With the advanced capabilities of the Garmin avionics, the relocation of the flight engineer's panel, and the new RADS-L tank, Coulson originally believed that the CU-47 could be crewed solely by two pilots, without a flight engineer. But recent operational experience led the company to rethink that strategy. “We realized that with a helicopter of this size, going into some of the smaller dip sites, to have an additional set of eyes looking out the side or back is valuable to the pilots. So we've de-modified the helicopter and gone back to a full-time flight engineer to provide that increased safety and situational awareness.” Like Coulson's C-130 conversions, the CU-47 can also be tasked with night-time firefighting missions, thanks to the Night Vision System (NVS) certification of the helicopter's avionics suite. Wearing NVS googles, the CU-47's crew work in tandem with a fire attack “Intel” helicopter's pilots. The Intel crew uses a thermal camera to evaluate the behaviour of a fire, and if a drop is required, they take a page from military ground-attack operations. Using a laser, the Intel crew designates the target for the tanker. “With a geo-referenced lock, the Intel helicopter can orbit, and the laser beam will stay on the same spot. It illuminates an area on the ground about the size of a car,” said Coulson. The first CU-47 will soon be joined by a second RADS-L equipped helicopter, two CU-47's with upgraded avionics that will fly “bucket” missions, and a fifth, tank-equipped CU-47 that will deploy as a spare. “All of our FAA testing [on RADS-L] has finished, we're just waiting for the final Supplemental Type Certificate signature,” said Coulson. “We're doing some minor cleanup to the helicopter to make sure that it's ready to go fight fires this summer.” Howard Slutsken's lifelong passion for aviation began when he was a kid, watching TCA Super Connies, Viscounts, and early jets at Montreal's Dorval Airport. He's a pilot who loves to fly gliders and pretty much anything else with wings. Howard is based in Vancouver, B.C. https://www.skiesmag.com/features/coulsons-cu-47-fire-fight
