  US Air Force looks to up-gun its airlift planes

  By: Valerie Insinna WASHINGTON — Humble airlift planes like the C-130J Super Hercules and C-17 Globemaster III could become heavily-armed weapons trucks capable of airdropping large bundles of munitions that deliver a massive blast. So far, the Air Force has conducted two successful tests of “palletized munitions” from the C-130 and C-17, said Maj. Gen. Clint Hinote, the deputy director of the service's Air Force Warfighting Integration Capability cell. “We are in discussions right now about how do we proceed to prototyping and fielding,” he said during a May 27 event held by the Mitchell Institute for Aerospace Studies. Like the name suggests, palletized munitions are a collection of weapons strapped together onto a smart pallet, which would feed the munitions tracking and targeting information as they are dropped from an airlift platform. A request for information released in February characterized the technology as “a bomb bay in a box” that could allow mobility aircraft to stay out of a threat zone and launch a mass of standoff weapons. “It's all about capacity,” Hinote explained. “You've got to create enough capacity so that a long-range punch is really a punch. What we see is that no matter how big our bomber force is, the capacity that the joint force needs is always more and more. And so this is why we think that there is a real possibility here for using cargo platforms to be able to increase the capacity of fires.” Air Force Special Operations Command conducted one demonstration of the technology on Jan. 28, when a MC-130J performed three airdrops of simulated palletized munitions at at Dugway Proving Ground, Utah. “In this case, munitions stacked upon wooden pallets, or Combat Expendable Platforms (CEPs), deployed via a roller system,” the Air Force Research Laboratory said in a May 27 release. “AFSOC aircrew released five CEPs rigged with six simulated munitions, the same mass as the actual weapons, including four Cargo Launch Expendable Air Vehicles with Extended Range (CLEAVERs) across a spectrum of low and high altitude airdrops." In response to questions from Defense News, AFRL clarified that simulated long-range cruise missiles were deployed from an off-the-shelf pallet system as well as an Air Force designed crate system. CLEAVER is a new weapon under development by the lab as part of a separate effort, though it may be used in palletized munitions in the future. On Feb. 27, Air Mobility Command conducted a similar demonstration with a C-17, which conducted two airdrops of simulated palletized munitions, AFRL said. In future demonstrations, AFSOC plans to release more advanced forms of simulated munitions as well as full-up weapons vehicles that can be configured with a warhead and terminal guidance system. However, the Air Force is looking for other technological options. Through its request for information, which closed in April, the service sought data about new or existing palletized munitions concepts. The service hopes to use that information to inform future experimentation efforts, operational assessments or the acquisition palletized munitions systems. Five companies responded to the RFI, AFRL said. If the effort moves forward, one big question will be figuring out which entities in the Air Force have command over a mobility asset that is playing a combat role more similar to a fighter jet or bomber. “Some kind of extremely streamlined command and control is going to be necessary, or else you must have an integrator somewhere,” said Hinote, who added that cultural barriers inside the Air Force could be harder to overcome than the technological challenges of creating palletized munitions. Hinote also acknowledged that it currently may be hard to find the funding to move forward with a new program. “We're in the last year of an administration. We've had to turn in the budget early with not too many changes, and we're looking at the possibility of a continuing resolution where new starts are going to be difficult to do,” he said. However, “that is all temporary,” he said.

  15 extra pounds of gear can be the difference between life or death in a firefight, this Marine officer’s research says

  By: Shawn Snow The weight being humped by grunts into a firefight with a sophisticated adversary like Russia or China could be the difference between mission success or going home in a body bag, according to one Marine officer's award-winning research. Marine Capt. Courtney Thompson said computer simulations she ran showed that just adding 15 pounds to the “bare essential” fighting load carried by Marines resulted in an additional casualty on the battlefield when Marines were pitted against competent shooters. The Corps' fighting load varies between 43 to 62 pounds depending on the level of body armor a Marine wears. Military body armor protection ranges from level II to IV. Thompson's simulations were run with level II body armor — protection capable of stopping a 9 mm round. The weight range includes a carried weapon. She told Marine Corps Times in an interview that the results of the simulations were “eye opening," especially in light of a 2017 government watchdog reported that detailed Marines and soldiers were carrying between 117 pounds to 119 pounds on average. When she ran the simulations and added more weight “casualties just went up,” Thompson said. And “the better the [enemy] shooter got, the more the difference in weight mattered." In a near-peer fight, Thompson said, Marines will need to move faster on the battlefield to survive and win. “The slower they are, the higher the chance they have of getting hit," she said. But it's not just about reducing a Marine's exposure time to being shot, smaller weight loads aid in more precise shooting and quicker target engagement times. A 2018 report from Washington D.C.-based think tank Center for a New American Security, explained that heavy combat loads “not only slows movement and increases fatigue” but decrease “situational awareness and shooting response times.” Moreover, a 2007 report from Naval Research Advisory Committee on Marine combat loads recommended an assault load of just 50 pounds. As the Corps focuses on the near-peer fight, the weight carried by Marines into battle is a topic that will need to be front and center for Marine commanders, Thompson said. Thompson's research, which won the Military Operations Research Society Stephen A. Tisdale Thesis Award at the Naval Postgraduate School in Monterey, California, has the attention of officials at the Marine Corps Warfighting Laboratory — where the Corps has been exploring ways to boost combat power while also reducing the weight burden on grunts. Marine Corps Times has reached out to the Marine Corps Warfighting Laboratory for comments on this research. Marine Corps Systems Command said its “Gruntworks” team spoke with Thompson about her research. The team handles the integration of equipment for Marine rifle squads. Thompson, a combat engineer, said she came up with the idea after seeing how “gassed” her Marines got during training as a result of operations tempo and weight. “I thought if I could quantify weight in terms of casualties and probability of mission success, that's what the Marine Corps understands,” she said. Thompson's computer simulations relied on Australian human subject data and infantry demographics supplied by headquarters Marine Corps. The Australian data was used because of the Australian Defence Department's rigorous study on its tiered body armor system, Thompson explained. The Marine infantry data included physical fitness and marksmanship. The individual Marines within the simulated 13-man rifle squads “represented the average for that rank for all 0311s [Marine rifleman] in the Marine Corps,” she said. Thompson said she ran the simulations nearly a million times. Thompson's research showed that reducing the weight burden carried by grunts could save lives and win battles. But she didn't make any prescriptive adjustments to the Corps' combat gear load outs. She told Marine Corps Times that she didn't want to “limit” a battlefield commander's decision-making. The Corps' various fighting loads are broken down in its infantry training and readiness manual into four different groups, fighting load, assault load, approach march load and sustainment load. The load type is dependent on the mission at hand. Thompson's research was aimed at the fighting and assault loads. The fighting and assault loads include combat gear for the “immediate mission” and the “actual conduct of the assault,” respectively, according to the Corps' infantry manual. The assault load weight varies between 58 pounds and 70 pounds based on level of body armor. The weight range includes a weapon being carried. The training and readiness manual excludes the weight of a weapon in its gear break down. Thompson isn't calling for particular pieces of gear to be thrown off the packing list, but she said commanders should throw the entire list in a pack, wear it, and “see if it is a reasonable amount of weight.” The Corps is already making a number of changes to reduce weight. Some of those include a new lightweight helmet, lighter body armor for counterinsurgency conflicts and polymer ammunition. But Marines also are packing on weight with new tech like tablets and drones, which have been dished out to rifle squads. At the end of the day, Marine commanders have a delicate balance of weighing risk verse capability, and it wont be easy for commanders to forgo pieces of equipment on a mission to lighten packs, Thompson explained. A commander “can't prove the lives they saved” from taking a particular action, Thompson said. https://www.marinecorpstimes.com/news/your-marine-corps/2019/06/18/15-extra-pounds-of-gear-can-be-the-difference-between-life-or-death-in-a-firefight-this-marine-officers-research-says/
