    Here’s the Philippine military’s wish list for its newly approved modernization phase

    By: Mike Yeo MELBOURNE, Australia ― The Philippine government has confirmed that the second phase of its military modernization plan has been approved by President Rodrigo Duterte, clearing the way for the southeast Asian nation to replace some of its elderly and obsolete equipment. The confirmation by Philippine Department of National Defense spokesman Arsenio Andolong on Wednesday will now allow the country to implement sorely needed recapitalization of some of its equipment, the oldest of which dates back to World War II. Andolong also confirmed that the budget for the five-year Horizon 2 modernization program, which will run from 2018-2022, has been set at some 300 billion Philippine pesos (U.S. $5.6 billion). According to sources in the Philippines, this amount will be split into $890 million for the Army, $1.44 billion for the Navy and $2.61 billion for the Air Force, with the rest of the budget going to the military's General Headquarters and the government's arsenal. The list of equipment the Philippines is seeking to acquire under the Horizon 2 program includes multirole fighters, airlifters, maritime patrol aircraft and heavy lift helicopters for the Air Force, while the Army is seeking more artillery, light tanks and multiple rocket launchers. The budget for the Air Force includes an amount set aside for combat utility helicopters. A contract signed in February with the Canadian government for Bell 412 helicopters was canceled after Canadian politicians raised concerns about the Duterte administration's human rights record in its ongoing war on drugs. The Philippines is reportedly now seeking to acquire the helicopters through a commercial sale, while an alternative option of buying the South Korean Korea Aerospace Industires Surion helicopter has also been floated. The Navy's priority will be the acquisition of two corvettes and a similar number of multirole offshore patrol vessels. Other items on its wish list include more anti-submarine helicopters and amphibious assault vehicles, the latter for the country's Marine Corps. Andolong also confirmed that the Navy wants to acquire an unspecified number of submarines under Horizon 2. However, this could prove difficult under a limited budget and because the country's has no experience operating and sustaining a submarine capability. The Philippines, which is an archipelagic nation made up of more than 7,600 islands, faces a myriad security challenges ranging from disputes with China and other southeast Asian countries over the ownership of islands and features in the South China Sea, to ongoing insurgencies with communist guerrillas and Muslim separatists that includes Islamic State-linked militants. In May 2017, the latter seized control of the city of Marawi in the southern Philippine island of Mindanao, leading to a five-month siege by government forces, which resulted in large parts of the city being badly damaged during operations to recapture it. During the operation, the United States, which has a mutual defense treaty with the Philippines, provided intelligence and surveillance assistance to government forces with its manned and unmanned aircraft. https://www.defensenews.com/global/asia-pacific/2018/06/21/heres-the-philippine-militarys-wish-list-for-its-newly-approved-modernization-phase/

    DIUx wants drones that are out for blood

    By: Kelsey Atherton 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: The specs of the solicitation from the Defense Innovation Unit Experimental -- the ability to deliver a 5-pound package over 100 kilometers in “austere environments” -- strongly suggest that they're looking at an unmanned aerial vehicle system that supports refrigeration or other means of temperature control. “These deliveries, ideally automated, will provide essential items to critically wounded military personnel as quickly as possible after an injury occurs,” the April 23 solicitation states. “Ability to sustain a very high frequency of operations over an extended period of time is critical. Speed of delivery, reliability and robustness to failure and interference, response time, and overall delivery throughput are critical.” 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. https://www.c4isrnet.com/unmanned/2018/05/03/diux-wants-drones-that-are-drones-out-for-blood/
