For drone delivery to make sense, with existing capabilities of drones, the cargo needs to be relatively light, it needs to have tremendous value, and it needs to urgently travel the last mile by air. This is why, to the extent we've seen drones used for delivery in the wild, it's more likely as a means to carry contraband into a prison than it is a practical alternative to the postal service.
But there's one other cargo that fits the description, and that's blood itself.
Defense Innovation Unit Experimental, the Pentagon's stand-up Silicon Valley-focused acquisition house, is looking for a drone that can carry a modest cargo of blood, through the dark of night toward where it's most needed. Call it “Dronesferatu.”
From FCW:
Getting the right blood to the right people as fast as possible means saving lives. To that end, DARPA's funded research into metabolic rate reduction to see if there's a way to make people bleed out more slowly, or into using female hormones to similarly prolong the survivable time without transfusion. In 2013, the U.S. Army conducted a study on pre-hospital transfusion for battlefield casualties being medically evacuated in Afghanistan, and in 2012 Canadian Blood Services even tested the viability of paratroopers transporting blood for transfusion.
Consider blood drones complementary to this field of work. Early tests by researchers at Johns Hopkins and Uganda's Makerere University proved that small vials of blood transported by drone were just as viable as blood transported by car. Those same researchers followed up with a test of blood delivery from ship-to-shore, for possible use in response to coastal areas hit by natural disasters, where the roads are impassable but drones could still safely fly. The American startup Zipline demonstrated its own blood delivery drones in 2016, and has for a year and a half worked on delivering blood by robot to parts of Rwanda.
DIUx's ask, that a drone fly over 60 miles and carry 5 pounds of blood, is not far off from what Zipline's drones can already do, with the company stating a range of 100 miles and a cargo capacity of just under four pounds. Weight and range tradeoffs are at the heart of aviation design, so it's likely that vendors have already pitched something within the bounds of the solicitation. Should that drone make a fast turnaround from ask to prototype to useful tool, the troops fighting abroad may gain a better shot at surviving otherwise-fatal blood loss. Unlikely that the reverse-vampire drones will look like bats, though.

By: Valerie Insinna WASHINGTON — The Air Force on Monday logged another critical technical flaw for the KC-46 tanker, this time revolving around excessive fuel leaks. Under its contract with the service, KC-46 manufacturer Boeing is responsible for paying for a fix to the problem, Air Force spokeswoman Capt. Cara Bousie said in a statement. “The Air Force and Boeing are working together to determine the root cause and implement corrective actions,” she said. “The KC-46 program office continues to monitor the entire KC-46 fleet and is enhancing acceptance testing of the fuel system to identify potential leaks at the factory where they can be repaired prior to delivery.” The problem was first discovered in July 2019, but the Air Force did not say why the issue had been escalated to Category 1 status — the designation given to problems with a significant impact on operations or safety. The service also did not immediately comment on questions about what sort of receiver aircraft were most involved with the deficiency or the severity of the problem. A Boeing spokesman said that the Air Force had discovered 16 aircraft in need of repair, and that seven have already been fixed. “The KC-46 fuel system is equipped with redundant protection for fuel containment. In some cases with this issue, aircraft maintenance crews are finding fuel between the primary and secondary fuel protection barriers within the system,” the company said in a statement. Boeing is working with “utmost urgency” to address the problem and implement a fix to the remaining aircraft, the statement said. A Boeing spokesman added it would take about 10 days to retrofit each aircraft at the rapid response depot facility in San Antonio, Texas. The fix was also being incorporated into production line in Everett, Wash., which is currently undergoing a temporary suspension due to COVID-19. The latest Category 1 deficiency brings the total up to four: The tanker's remote vision system or RVS — the camera system that allows KC-46 boom operators to steer the boom into a receiver aircraft without having to look out a window and use visual cues — provides imagery in certain lighting conditions that appears warped or misleading. Boeing has agreed to pay for potentially extensive hardware and software fixes, but the Air Force believes it will system won't be fully functional until 2023-2024. The Air Force has recorded instances of the boom scraping against the airframe of receiver aircraft. Boeing and the Air Force believe this problem is a symptom of the RVS's acuity problems and will be eliminated once the camera system is fixed. Boeing must redesign the boom to accommodate the A-10, which currently does not generate the thrust necessary to push into the boom for refueling. This problem is a requirements change by the Air Force, which approved Boeing's design in 2016. Last year, Boeing received a $55.5 million contract to begin work on the new boom actuator. Boeing's fixed-priced firm contract for the development of the KC-46 has a $4.9 billion ceiling that leaves the company responsible for any expenses billed in excess of that amount. So far, the company has paid more than $3.5 billion of its own money to fund corrections to ongoing technical issues. https://www.defensenews.com/air/2020/03/31/the-air-forces-kc-46-tanker-has-another-serious-technical-deficiency-and-boeing-is-stuck-paying-for-it/

By: Tom Kington ROME – Plans by Italy and France to win European Union funding for the construction of a new corvette have been boosted as Spain looks set to follow Greece and sign up to the program. The planning for a new 3,000 ton corvette is a cornerstone of the new naval joint venture between Italy's Fincantieri and France's Naval Group which was launched last year and named Naviris. The two firms are hoping to match Italian and French navy requirements with a jointly built, modular vessel that can handle patrol and surveillance missions as well as taking second-tier roles in anti-submarine and anti-surface missions. The program, dubbed the European Patrol Corvette, has also been inserted in the EU's so-called Permanent Structured Cooperation, or PESCO, list of recommended pan-European defense programs, which according the EU offers members “options on how to plan and bridge capability gaps in a collaborative manner.” The PESCO corvette project is coordinated by Italy, with France as partner, but in recent weeks, Greece has also joined as a partner, following discussions between the countries' navies. And now Spain is likely to follow, an industrial source told Defense News. “Naviris presented the program to Spain's Navantia which is interested and it is likely Spain will sign up,” said the source. On its PESCO listing for the corvette, the EU states “the objective is to design and develop a prototype for a new class of military ship, named “European Patrol Corvette” (EPC), which can host several systems and payloads, in order to accomplish, with a modular and flexible approach, a large number of tasks and missions.” Adding new partners to the roster of Italy and France is key to winning EU funding. PESCO programs are possible candidates for cash from the European Defence Fund, but only if they have more than two partners on board. “The corvette is the only naval program on the PESCO list and it should be a priority,” said the source. Naviris expects the EU fund to issue a Request for Proposal for projects this year, with proposals to then be submitted by industry in 2021, and for decisions on fund allocation to be made the same year. The source said that if the corvette program gets EU part-funding, it would help sustain the development of the ship's modularity, allowing it to serve different functions for different navies. “It would have a very open architecture, as well as having a basic and enhanced version,” he said. Apart from the boost given the program by potential EU funding, the corvette remains a requirement for Italy and France. Rome needs to replace Cassiopea- and Minerva-class vessels being phased out as well as aging Commandante-class vessels. France is looking to substitute its Floréal-class vessels. “Italy might need eight corvettes and France is looking to substitute six ships. They both have a need, so the EU funding would be an added opportunity that could create a bandwagon effect with other navies,” said the source. As Naviris picks up steam, Naval Group CEO Hervé Guillou has said the industrial alliance is open to new partners joining, but so far Germany seems to be uninterested. Addressing the economic affairs committee of the French Senate on Jan. 28, Guillou said he had visited Berlin the week before to sound out German interest but got little response. https://www.defensenews.com/global/europe/2020/02/07/spain-seen-joining-greece-france-italy-on-european-patrol-corvette-program
