Hmmm.  IIRC the BGRV managed thousands of miles without heating issues half a century ago.  ???  Also, I'd thought they made some breakthroughs in thin-section aero surfaces WRT heating years ago.

Columbium shingles and water-wick cooling, IIRC.  Sadly, as we know from stories like FOGBANK, the fact that we could do it in 1968 doesn't mean we can do it today.

Yep.  You'd think they'd have at least given past success a look.

SSP is currently assessing the means to implement the goals set in the FY18 National Defense Authorization Act (NDAA) for rapidly developing and prototyping a Navy Conventional Prompt Strike (CPS) Weapon System (WS) for integration into and tactical deployment on sea-based launch platforms to meet a time-critical national need. The Navy CPS WS will consist of the following primary subsystems:


•·       Large-diameter (>30 inches) All Up Round (AUR) [encapsulated missile with a Hypersonic Glide Body (HGB)].


•·       Weapon Control System (WCS) for Fire Control.


•·       Advanced Payload Module (APM) with AURs in a three-pack configuration. The APM interfaces the AUR to the host platform and includes a support structure, protection, compressed air ejectors, and environmental control not provided by the host platform.


•·       Shipboard Information System (IS) to provide technical documentation, training, data logs, other technical information onboard the host platform, and potential interfaces to offboard support systems.

Nice, Midgetman was only 46in diameter. Need about 3k range for SCS operations.

Just trying to keep them straight.  So we have (pulled from a couple different articles recently posted):

1.  AGM-183A - Air-Launched Rapid Response Weapon (ARRW). "The ARRW, like many of the emerging threats, is an air-launched, rocket-boosted unpowered hypersonic glider. To be developed under a $480 million initial contract, potentially worth $780 million including early production through 2023, the ARRW work is an extension to Lockheed’s pre-existing DARPA contract under which it is building the virtually identical Tactical Boost Glide (TBG) demonstrator."  Lockheed Martin Missiles and Fire Control

2. Hypersonic Conventional Strike Weapon (HCSW). The HCSW is a solid-rocket-powered, GPS-guided missile, and is targeted at initial operational capability on existing combat aircraft in fiscal 2022. Lockheed Martin Space Systems

3. Hypersonic Air-breathing Weapon Concept (HAWC).  A scramjet-powered missile demonstrator similar in concept to the Air Force Research Laboratory/Boeing X-51A scramjet-powered vehicle that exceeded Mach 5 in a 2013 flight test. Both Lockheed Martin Skunk Works and Raytheon

4. Raytheon, which is partnered with Northrop Grumman Innovation Systems (formerly Orbital ATK) on the scramjet for HAWC, is also in final negotiations with DARPA to develop and test a TBG glide demonstrator. Raytheon’s newest work is believed to be supporting DARPA development of a ship-launched TBG for the U.S. Navy. In July, Lockheed was awarded a $40.5 million Navy Hypersonic Booster Technology Development (HBTD) contract, also believed to be related to this effort.

5. Another one of the projects in the Technology Transition Program is the Advanced Full Range Engine (AFRE), which aims to demonstrate a hybrid propulsion system that would utilize a traditional turbine engine and transition to a Dual Mode Ramjet (DMRJ) for hypersonic travel. Ground tests are planned for 2019 or 2020. This is a joint effort between DARPA and the National Aeronautics and Space Administration (NASA). 

6. The Army and Navy are also working on developing hypersonic capabilities. The Army is working with DARPA on studying a ground-launched capability for hypersonic boost glide weapons through the Operational Fires project. This effort was funded at $6 million in FY18 and $50 million in the FY19 request. Operational Fires will also leverage work done on the Air Force TBG program. The Army was previously conducting work on the Advanced Hypersonic Weapon (AHW). A successful flight test was conducted in November 2011, but an August 2014 flight test failed due to a problem with the booster rocket used to launch the glide vehicle.

7. The Navy was tasked with a follow-on test using a downsized hypersonic vehicle. (CPS?) Downsizing provides the Navy with the ability to analyze possible future ship-launched capabilities. The Navy's Strategic Systems Programs office conducted this test in October 2017, dubbed Flight Experiment-1. A rocket carrying the glide vehicle was launched from Hawaii, after which the glide vehicle flew more than 2,000 miles in about 30 minutes. Other details of the test were classified.

8. In addition to the ARRW, HCSW, TBG, and HAWC, Lockheed's "Skunk Works" is believed to still be working on the High Speed Strike Weapon, which sources say is a tactical missile in the Mach 3-plus category that resembles its D-21 drone, which USAF launched from SR-71s and B-52s in the 1970s. The HSSW is derivative of the Revolutionary Approach to Time Critical Long Range Strike program Lockheed explored with the Navy in the early 2000s.  (This sounds more like speculation as they seem to be conflating two different programs.)

"The veil of secrecy has lifted over one of the Pentagon’s largest hypersonic weapons programs, revealing new details of a triservice rush to adapt a nearly 40-year-old experimental maneuvering reentry vehicle concept into an air-, sea- or land-launched common-boost-glide weapon.

The revelations provide deeper insight into plans that unite three separate projects—the U.S. Army’s Advanced Hypersonic Weapon (AHW), the Air Force’s Hypersonic Conventional Strike Weapon (HCSW) and the Navy’s Conventional Prompt Strike (CPS)—under a single Defense Department-wide program to field a Mach 6 missile by 2021."

Deputy Defense Secretary Patrick M. Shanahan, in a keynote address at the conference, said the commercial aircraft industry is far ahead of the US military in understanding aircraft sustainment and wringing savings out of it.

The military should be “humble” and learn from “those who do it well.” Shanahan said the military should “rip off and deploy the tools and systems” aircraft maintainers need to get the job done faster and at less cost.

According to Roper, the Hypersonic Conventional Strike Weapon (HCSW, pronounced “Hacksaw”) could be operational as soon as December 2020. It’s “a fact that we can compress the development into two years,” he said, although admitting that dates could slip because of the need to “test aggressively.”

The HCSW will then follow a “spiral development” plan, Roper said.

“You’ll go into some low rate of production, then keep spiraling the technology until you get enough bells and whistles on the weapon and you say, ‘That’s the one I want to buy,’ ” he explained. Too many programs have faltered in the past because the service attempted to reach the objective capability in the initial version. That resulting “concurrent risk” slowed development and jacked up cost.

“We’re trying not to do this” with hypersonics, Roper said.

The HCSW is only one of at least four hypersonic projects USAF is pursuing, including boost-glide munitions and air-breathing missiles with longer range and maneuverability.

Among the US Armed Forces, the Air Force is “out of the starting gates the fastest” on hypersonics and will likely be the first to have an operational weapon, Roper said. The services are working together though. Air Force Secretary Heather Wilson said cooperation with the Army and Navy has already “saved 10 years” of development effort. The services are sharing effort on overlapping technologies, while leaving each free to concentrate on their unique launch requirements.

They have agreed “to use the best technology, no matter where it comes from; go fast, share results, and build harmony,” Wilson said.

Roper said the HCSW and test models from the other services would likely be test-launched from B-52s.

Lockheed Martin's EVP for Missiles & Fire Control, Frank St. John, lays out the company's work on hypersonics -- and how it's not really a new thing.

The U.S. Missile Defense Agency (MDA) has joined the Army, Air Force and Navy in a partnership formed to urgently develop a new hypersonic weapon within about three years, the Army confirmed to Aerospace DAILY Oct. 22.

MDA’s role in the Hypersonic Glide Body (HGB), which has not previously been disclosed, allows the agency to acquire a relevant missile to use as a target.
