By Steve Trimble Beyond seven acknowledged projects aimed at developing long-range, maneuvering missiles with a top speed over Mach 5, the U.S. Defense Department is working in classified secrecy on at least two more hypersonic weapon programs, industry officials say. The mystery of the classified projects—including such details as their development or operational status and any gaps each fills in the Pentagon's unfolding hypersonic weapons architecture—remains unsolved. But a new clue embedded in the LinkedIn profile of a senior Defense Department hypersonic weapons expert may point to the answers. Seven U.S. hypersonic projects cover air-, land- and sea-based weapons Pentagon expert's online profile points to existence of two more programs Greg Sullivan, a well-regarded expert in the high-speed flight community, describes himself on the professional social media platform as an on-site supporter of air-breathing hypersonic weapons to the department's research and engineering arm. Sullivan's profile also cites his knowledge of “additional hypersonic programs,” which include a nearly comprehensive list of the Pentagon's acknowledged projects. Intriguingly, his original list also included two additional acronyms representing hypersonic programs: “HACM” and “HCCW.” Shortly after Aviation Week inquired to the Air Force Public Affairs office for details about HACM and HCCW, both acronyms were deleted from the LinkedIn page. The Air Force does not acknowledge the existence of any program named HACM or HCCW, and no reference to either acronym appears in the military's public documents, such as budget materials and press releases. Two sources say they have heard vague references to the existence of a hypersonic program called HACM, but had no details, including what the acronym means. The HCCW program was not known to any sources or analysts contacted by Aviation Week. The expert hypersonic community is an unusually tight-knit group, reflecting the technology's mostly experimental status for decades, until its recent rise as one of the Pentagon's top acquisition priorities. The existence of two new acronyms has prompted several speculative guesses. Richard Hallion, a former Air Force chief historian who specializes in the history of hypersonic technology, noted that the acronym HACM could be interpreted broadly to cover almost any type of hypersonic weapon, including scramjet-powered cruise missiles or air-launched boost-glide systems. “Well, the H is obviously [for] hypersonic,” says Hallion. “The rest suggests a mix of ‘A' for ‘Advanced' or ‘Air-Breathing' or ‘Air-Launched.' ‘C' for ‘Conventional' or ‘Capability' or ‘Concept,' [and] ‘M' for ‘Missile.'” The meaning of the HCCW acronym proves even more elusive. For Justin Bronk, a research fellow specializing in airpower at the Royal United Services Institute, one speculative interpretation conforms to his analytical view of a gap in the U.S. military's weapons arsenal. If the acronym stands for “Hypersonic Counter-Cruise Weapon,” Bronk says, HCCW could be a valuable interceptor specifically tailored against high-speed, air-breathing cruise missiles. Although the exact role and status of HACM and HCCW are unknown, industry officials have repeatedly said that at least two additional classified programs exist beyond the Defense Department's seven acknowledged programs. The public list leaves little room for gaps to be filled by new weapons, as they already span air-, land- and sea-launched options and include two different types of boost-glide systems—winged and biconic—and a scramjet-powered cruise missile. The plethora of planned hypersonic options are intended to serve tactical and strategic goals. On the tactical level, the Pentagon's war planners will gain a new option for striking mobile missile launchers and countering long-range attacks on the Navy's surface fleet by an adversary with hypersonic anti-ship missiles. The future U.S. inventory of hypersonic missiles also is intended to serve as a deterrent option short of a nuclear response, as adversaries such as China and Russia stock their arsenals with a range of new hypersonic weapons. The Air Force alone accounts for two of the acknowledged hypersonic weapon programs: a boost-glide system with a winged glide vehicle called the Air-launched Rapid Response Weapon (ARRW). Another called the Hypersonic Conventional Strike Weapon (HCSW) relies on a less-risky biconic glide vehicle. The ARRW, also known as the Lockheed Martin AGM-183A, is based on the Tactical Boost Glide (TBG) program, a risk-reduction effort funded by DARPA. The same winged glide vehicle also is being adapted for ground launch under DARPA's Operational Fires (OpFires) program. Raytheon says it is developing a more advanced winged glider under the TBG program, which could be fielded as a second-generation version of ARRW. HCSW, meanwhile, is the air-launched version of a biconic-shaped glider originally designed by Sandia National Laboratories. The Navy and Army are adapting the same original design for the sea-launched Conventional Prompt Strike (CPS) system and the Army's ground-launched Long-Range Hypersonic Weapon (LRHW). Finally, Raytheon and Lockheed are each designing different scramjet-powered missiles under DARPA's Hypersonic Air-breathing Weapon Concept (HAWC) program. Weaponized versions of HAWC are under study by the Air Force and Navy for air and sea launch. One possible gap in the weapons portfolio is the apparent lack of an operational follow-on program for HAWC, even though Air Force officials say the program is slightly ahead of DARPA's TBG program. The TBG demonstrator is intended to reduce risk for the operational ARRW system, but no such operational follow-on exists publicly for HAWC. Tom Bussing, vice president of advanced missile systems for Raytheon, acknowledged two hypersonic programs exist that he cannot speak about. “There are probably six different types of hypersonic programs that we have,” Bussing said in a recent interview. “Some are classified, so I can't speak [about] them because we are not at liberty to announce them.” But he named Raytheon's role in four hypersonic programs: TBG, HAWC, CPS and LRHW. DARPA has announced Raytheon's involvement as one of two weapon designers for TBG and HAWC, but neither the Navy nor the Army has explained Raytheon's role in CPS and LRHW. The Air Force has announced that Lockheed is the weapon system integrator for the HCSW variant, but no such role has been announced for the Army and Navy versions of the common glide vehicle. So far, Bussing can only acknowledge that Sandia remains the designer of the biconic glider for HCSW, CPS and LRHW. “That technology has been transitioned over to the CPS program and also to the Army's Long Range Hypersonic Weapon program,” Bussing said. “So we're involved in both, and we're working directly with Sandia.” The Defense Department has inserted $10.5 billion into a five-year budget plan released in March to develop and field the long list of offensive and defensive hypersonic weapon systems. But a detailed check of the budgets for unclassified programs reveals a significant surplus, which could be used to fund classified projects. The combined budget accounts for ARRW, HCSW, CPS and LRHW amount to $7.7 billion over the next five years. The Missile Defense Agency's $700 million planned investment in counter-hypersonics raises the five-year spending total to $8.36 billion. DARPA does not release a five-year budget, but proposed to spend $222 million in fiscal 2020 on TBG, HAWC and OpFires. That still leaves an unexplained gap of about $2.5 billion in planned spending by the Defense Department on hypersonic weapons over the next five years. https://aviationweek.com/missile-defense/clues-emerge-search-pentagon-s-classified-hypersonic-programs

By: Mark Pomerleau As the Army moves forward with its multipronged network modernization, the branch has set its sights on servicewide communications capabilities integrated from top brass down to the smallest tactical units. Army leaders expressed the need for technologies to enable units' communication from the tip of the spear down to systems in vehicles and at command units. “The ‘integrated' part of ‘integrated tactical network' is making sure we don't field a set of stovepiped capabilities that do not provide the robust capability that we think we want for the future fight,” Maj. Gen. David Bassett, program executive officer for Command, Control, Communications-Tactical, told C4ISRNET. “We've got to field this as an integrated capability. It's not just about focusing on one piece or the other. We've got to work it all together along with network operations tools that help soldiers employ those system.” The Army's integrated tactical network (ITN) is described as a mix of existing programs of record and commercial off-the-shelf capabilities that allow a unit to communicate in congested environments and provide situational awareness. The network also feeds into programs such as the Command Post Computing Environment (CPCE). CPCE is a web-enabled system that will consolidate disparate command post tools, programs and tasks and help the Army to react faster than the enemy. This includes the Tactical Ground Reporting System (TIGR), Global Command and Control System-Army (GCCS-A), Command Web and Command Post of the Future (CPOF). This uniform interface will be available from the command post to ground vehicles to dismounted soldiers, allowing each to upload and share information in a centralized database. During exercises last year, soldiers worked through how to identify targets on the ground and pass that information through the network via vest-mounted tablets and a Google Maps-type function. “Target acquisition from an operator's perspective starts in the ITN. Then it will make its way eventually to CPCE if we can get the ITN and CPCE to talk to each other, which is definitely the next bridge line for these systems,” Maj. John Intile, executive officer for 1st Battalion, 508th Parachute Infantry Regiment, 82nd Airborne Division, told C4ISRNET during a battalion event at Camp Atterbury, Indiana. The Army's fire support Command and Control (C2) system, Advanced Field Artillery Tactical Data System (AFATDS), is slated to be incorporated in CPCE after the first round of aforementioned systems. “While the integrated tactical network in our first line of effort is focused on the lower echelon war-fighting units, the Command Post Computing Environment ... is really done at the corps and down trace units,” Maj. Gen. Peter Gallagher, director for the network cross-functional team, told C4ISRNET. https://www.c4isrnet.com/c2-comms/2019/05/31/the-army-wants-to-talk-to-anyone-anytime-anywhere/
