Japan unveils its hypersonic weapons plans

By: Mike Yeo

MELBOURNE, Australia — Japan has outlined its research and development road map for its homegrown, standoff hypersonic weapons, confirming that it is seeking an incremental growth in capability and providing more details about the kinds of threats it is targeting with this new class of weapon.

In a Japanese-language document published on the Acquisition, Technology and Logistics Agency website, the government said two classes of standoff hypersonic systems will be deployed — the Hypersonic Cruise Missile (HCM) and the Hyper Velocity Gliding Projectile (HVGP).

The former will be powered by a scramjet engine and appears similar to a typical missile, albeit one that cruises at a much higher speed while capable of traveling at long ranges.

The HVGP, on the other hand, will feature a solid-fuel rocket engine that will boost its warhead payload to a high altitude before separation, where it will then glide to its target using its altitude to maintain high velocity until impact.

The agency also provided more details regarding warhead payloads, with different warheads planned for both seaborne and land targets. The former will be an armor-piercing warhead designed specifically for penetrating “the deck of the [aircraft] carrier,” while a land-attack version will utilize a high-density, explosively formed projectile, or EFP, for area suppression.

Area suppression effects for the latter will be achieved via the use of multiple EFPs, which are more commonly known as a shaped charge. An EFP is made up of a concave metal hemispherical or cone-shaped liner backed by a high explosive, all in a steel or aluminum casing. When the high explosive is detonated, the metal liner is compressed and squeezed forward, forming a jet whose tip may travel as fast as 6 miles per second.

Japan's road map also revealed the country is taking an incremental approach with regard to designing the shapes of warheads and developing solid-fuel engine technology, with plans to field early versions of both in the 2024 to 2028 time frame. They are expected to enter service in the early 2030s.

The agency expects both systems to navigate via satellite navigation with an inertial navigation system as backup. Japan is seeking to establish a network of seven satellites to enable continuous positioning for its self-defense forces, which will enable it to provide continuous navigation data without relying on foreign satellites.

Warhead guidance is achieved via either radio-frequency imaging converted from doppler shift data — which the government agency said will be able to identify stealthy naval targets in all weather conditions — or an infrared seeker capable to discriminating specific targets.

Japan has been conducting R&D into various areas related to hypersonic weapons for a number of years, although most of it was to benefit other fields like satellite navigation and solid-fuel rockets.

More work remains, however, in areas like hypersonic guidance systems, warhead and missile-body thermal shielding, and hypersonic propulsion systems in order for Japan to be able to field a viable standoff hypersonic weapons capability.

New Air Force leaders view plans for more virtual pilot training
Stephen Losey The Air Force's new military leaders, Chief of Staff Gen. Charles “CQ” Brown and Chief Master Sergeant of the Air Force JoAnne Bass, made their first trip with Air Force Secretary Barbara Barrett Thursday. The leadership team traveled to Joint Base San Antonio-Randolph in Texas, where they were shown Air Education and Training Command's plans to take lessons from its virtual reality and artificial intelligence-infused pilot training experiment, called Pilot Training Next, and incorporate them into a new version of undergraduate pilot training, which the Air Force is calling UPT 2.5. In a conference call with reporters Friday, Barrett said the leadership team was “celebrating innovation” and airmen during their trip. The trio also visited AFWERX, the Air Force's innovation hub in Austin, and saw some of the programs it is working on. One of those, Agility Prime, aims to improve logistics and transportation with “flying cars, very Jetsons-like,” Barrett said. Barrett said the Air Force expects virtual pilot training not only will produce pilots cheaper and faster, but also better. Brown, who became the 22nd chief of staff Aug. 6, said that taking care of airmen and their families, and ensuring their quality of service and quality of life remain high, are among his top priorities. That is why he, Barrett and Bass decided to come to Randolph for their first trip together, he said, to see how the Air Force develops its future leaders. “We start leadership development the first day they walk in the door,” Brown said. “That, to me, is important, particularly when you look at the dynamics of what we're dealing with, whether it's COVID, racial disparity, potential budget pressures, high-end fight.” https://www.airforcetimes.com/news/your-air-force/2020/08/22/new-air-force-leaders-view-plans-for-more-virtual-pilot-training/

Lockheed, Boeing enter Germany’s heavy transport helicopter race
By: Sebastian Sprenger COLOGNE, Germany — Lockheed Martin's Sikorsky and Boeing have submitted their proposals for the German military's envisioned heavy transport helicopter program, the companies announced. Sikorsky is offering a version of the CH-53K designed for the U.S. Marine Corps, while Boeing is pitching the H-47 Chinook. The offers, due on Jan. 13, come in response to a request for proposals published by the Bundeswehr last summer. Government officials will spend the greater part of 2020 analyzing the submissions, with a second and final request for offers pegged for the end the year. The multibillion-dollar STH program, short for Schwerer Transporthubschrauber, is meant to replace the German fleet of decades-old CH-53G copters. Deliveries from the winning bidder are slated to begin in 2024 and last through the early 2030s — that is if the program receives budgetary support from the government and lawmakers when the time comes for a contract next year. Both companies have assembled a group of German suppliers that would oversee areas such as maintenance, simulators and documentation in an effort to maximize domestic industry participation. The Bundeswehr initially wanted a no-frills, off-the-shelf cargo helicopter that would be easy on the defense budget. Notably, the Germans also want to use the STH choppers for combat search-and-rescue operations, with plans to raise that mission profile throughout the Air Force's ranks. But last year's solicitation came with an unexpected level of complexity, Frank Crisafulli, Sikorsky's director of international business development for heavy helicopters, told reporters during a company presentation in Bonn, Germany, on Monday. “Folks were caught by surprise,” he said. The added complications are due, for example, to the Bundeswehr's goal of having the helicopters certified in accordance with European civilian aviation regulations. In addition, German officials want a weather radar better than the one offered in the Marine Corps version of the CH-53K, plus a multilayered radio communications setup," Crisafulli said. As envisioned, the STH program would plunge the German military into a model of contractor-driven support popularized by the U.S. Defense Department under the moniker of performance-based logistics, or PBL. The idea is that the government can save money by dictating to contractors what level of readiness it wants for its hardware, and then letting vendors figure out how to meet those objectives within a given budget. Pentagon auditors previously affirmed the basic premise of performance-based logistics, with one key caveat: The government must have enough insight and clout in the programs to be able to set sensible performance benchmarks at rates favorable to taxpayers. According to Mike Schmidt, CEO of Rheinmetall Aviation Services, one of Sikorsky's key local partners, the concept is relatively new for Germany. At an STH industry day in 2018, “nobody knew what PBL was,” he said. At stake for the contractors is a 40-year relationship with Germany over the life cycle of the program. Boeing has portrayed its Chinook offering as a low-risk and low-cost option because more than 950 of the aircraft are already used by 20 countries. Sikorsky has played up the aerial-refueling capabilities of the CH-53K, especially in conjunction with the Lockheed Martin-made KC-130J tanker, to increase range. https://www.defensenews.com/global/europe/2020/01/14/lockheed-boeing-enter-germanys-heavy-transport-helicopter-race/
