AIM-260

Another missile has been recently unveiled to a degree, the Lockheed AIM-260 air-to-air missile, a replacement for the AIM-120 AMRAAM:

Air Force Developing AMRAAM Replacement to Counter China

Not much known about it as yet, other than it will have a longer range than AMRAAM and will fit in the F-22’s missile bay. Rumors abound, including the possibility that it is two-stage, or that it may be an airbreather of some kind.

It *seems* that the US is starting to crank up new weapons systems. Which, if true… ABOUT DAMN TIME. But the real test will be not just ‘weapons in development,” but “weapons in mass production and put into service.”

A Mach 20 Arrow

In response to both Russia and China claiming to have develop hypersonic weapons, the USAF has awarded contracts to Lockheed for two new hypersonic missile systems: the AGM-183A Air-launched Rapid Response Weapon (ARRW: “arrow”) and the Hypersonic Conventional Strike Weapon (HCSW: “hacksaw”). Little info is publicly available about them just yet (though it’s a safe bet that the Chinese have a complete set of plans; I’d be unsurprised if they had real-time access to the workstations being used to design them), but the ARRW is a boost-glide system that uses a rocket motor to launch a hypersonic glider to around Mach 20. This is not a particularly new idea; ground launched ideas like this go back more than fifty years, with air-launched versions seriously considered at least as far back as the 1980’s. The image below, taken from the SDASM Flickr page, shows a (presumably 1980s) General Dynamics design for an air to surface missile using a twin-engined rocket booster (presumably solid fuel) with a hypersonic glider.

The Lockheed ARRW is likely similar in concept if not detail. The basic idea of a rocket-booted glider is the most practical approach to long-range hypersonic strike weapons, though it’s not as flashy or trendy as airbreathing system such as scramjets. but while rocket systems would weigh more than an air breather, quite possibly by a lot, they would be much more reliable, cheaper to develop and capable of *far* greater speed. The ARRW, after all, is supposed to reach Mach 20. A scramjet would be damned lucky to exceed Mach 10, and testing has shown that a scramjet would but damned lucky to maintain that speed for long.

The heavier gross weight of a rocket system compared to an airbreather means that an aircraft could carry fewer weapons. The obvious solution is to build more carrier aircraft. While there will be no more B-1B’s or B-2’s, the B-21 *may* be built, though unlikely in any real numbers. A more practical solution might be to build specialized carrier aircraft, perhaps based on modified jetliners, perhaps even made unmanned, designed to fly in massed armadas with one or two manned control planes.

PDF Review: Chance-Vought Apollo Lunar Lander design

One of the documents lost from the NASA Technical Report Server when NASA gutted it in 2013 was a Chance Vought corporation report on a simulator for their lunar lander. The “Apollo Rendezvous Simulator Study” from July 1962 focuses of course on a ground-based simulator, not on a detailed design of their lunar lander… but fortunately the documents do show art and diagrams of the lander. It is an odd looking little bug, with giant windows and a configuration similar to the Soviet LK in that there were no distinct descent and ascent stages, but a single manned vehicle that would leave the landing legs and some tanks behind when it lifted off.

Fortunately, even though it was scraped from the NTRS it can still be found on the Internet Archice/Wayback Machine. Huzzah!

“Mighty Mouse” in full rez

I made the full rez scan of this artwork available in 2015 to APR Monthly Historical Document Program subscribers as an “extra.” Subscribers get lots of stuff like this.

This late 1980’s art depicts the Bell “Mighty Mouse” tiltrotor, a contender for the FAAV (Future Attack Air Vehicle) concept. While details on this specific design have remained irritatingly hard to come by for the last thirty years, the design looks like functionally a VTOL OV-10 Bronco. Capable of carrying several Marines as well as a useful load of anti-tank weaponry, the Mighty Mouse would be able to fold up for storage on board a ship. The full rez version of the scan is on Dropbox HERE.

How to carry your FISH

FISH (“First Invisible Super Hustler”) was a ca. 1958 Convair design for a Mach 4 ramjet powered recon aircraft. As ramjets are terrible at accelerating from the runway to cruise speed, the FISH was to be carried underneath a B-58 bomber. The FISH was a relatively small craft, but not *that* small; it actually didn’t quite fit underneath the B-58. Consequently it’s nose was designed to fold down and back while the B-58 was on the ground, providing clearance for the B-58’s nosegear. After liftoff and gear retraction the nose would fold up into its proper position. This would clearly have required fairly powerful actuators as the nose would basically be a substantial drag brake as it folded forward into position.

The FISH was described in the first issue of US Recon & Research Projects, available HERE.

The FISH was derived from the prior “Super Hustler” design study for a ramjet powered Mach 4 parasite bomber to be carried under the B-58. In the case of the Super-Hustler, a special booster stage was used, basically creating a three-stage vehicle. The FISH, if it worked, would have been a masterpiece of engineering, but the requirement for a carrier aircraft was cumbersome to say the least. It was followed by the single-stage “Kingfish,” but in the end the Lockheed SR-71 was chosen. Not quite as fast as FISH, but much more practical.

Some further tinkering to the USLP06 diagrams. There will be further revisions (especially with Star Raker), but I believe this will be the complete set of vehicles shown. I had to split the set up into two separate files; the unified diagram set was causing my computer headaches. You might not think that 2D diagrams can overload computers that can render things in 3D, but you’d be wrong.

This latest effort has taken a *really* long time. Lots of work involved with this. As a result, it has been a long time since I’ve published anything else, and since my income is based on getting stuff published… yay, welcome to poverty. If you want to help out, consider Buying Stuff or subscribing to the Monthly Historical Documents Program. Even a buck fifty a month helps out.

Two pieces of Boeing concept art for mid-1960’s zero-gravity, single-Saturn V launched spacecraft. The first one looks like an interplanetary spacecraft, complete with drop-probes in the aft skirt.

I have uploaded the full resolution scan of the illustrations to the 2019-06 APR Extras Dropbox folder, available to $4 and up subscribers to the APR Monthly Historical Documents Program.

RIP Stratolaunch

In the least shocking news of the day…

Space firm founded by billionaire Paul Allen closing operations – sources

Right now it’s not official, it’s “sources say.” But Stratolaunch never made a lick of business sense, and going belly-up has seemed inevitable. As an ego project for a bajillionaire… sure. It’s no worse than a Russian oligarch or a Saudi prince splurging on a yacht the size of a battlecruiser; but once that bajillionaire is out of the picture – in this case, dead – the driving force behind it evaporates. And without a sound business case… shrug.
