The Commercial, but the music is better than average

When I was working at BAE Systems on the FCS-RMV, one of the systems that we needed to place on our vehicle was the so-called “Active Protection System” (APS), Raytheon’s “Quick Kill, a hit-to-kill interceptor intended to neutralize RPGs, ATGWs, and long rod KE penetrators.

One of the problems with this system, at least as if fed down to us doing the design, was that it never worked properly, which was surprising, considering that the Israelis had a system, Trophy, which worked, and was far less expensive than the APS.

Of course, because of the need for generals to find lucrative consulting gigs in retirement, Trophy was fought tooth and nail by the army, with their refusing to test the system on Strykers in Iraq.

Well, what goes around comes around, and with Raytheon basically dead, the US army will finally try out the system on a Stryker:

Next month a Stryker combat vehicle will arrive in the US equipped for testing the Israeli’s Trophy active protection system. The Army has pursued active protection for years, most recently abandoning the Future Combat System’s active protection system developed by Raytheon. We understand at least one M-ATV will also get the radar– directed system. The M-ATV integration is more challenging, given the vehicle’s design.

Seriously, it’s been something like 6 years that the Pentagon has refused to test the system, instead holding out for a system that was never near ready because our defense procurement system is that broken.

Prosecution Doing Back-Flips For Goldman Sachs in High Frequency Trading Trial

No Comments

If there was any doubt that the federal prosecutors in New York prosecuting Sergey Aleynikov for theft of trade secrets weren’t in Goldman Sach’s Pocket, those doubts have been allayed:

Goldman Sachs Group Inc. has always closely guarded the secrets of its lucrative high-speed trading system. Now the securities firm is getting a help from an unusual source: federal prosecutors.

Federal prosecutors in Manhattan this week asked a federal district judge to seal the courtroom at the forthcoming trial of a former Goldman computer programmer accused of stealing the firm’s computer code. The move was a formal request to empty the courtroom of the general public when details of Goldman’s trade secrets are being discussed. The trial is set to start to late November.

Prosecutors also asked that any documents related to Goldman’s trading strategies remain under seal.

Such requests are common when proprietary corporate information could be exposed in a trial, lawyers say. This case is unusual in that it involves secrets about a potentially lucrative trading system, rather than, say, ingredients in a soda formula.

What is also unusual is that this code is almost certainly obsolete, and almost certainly has no value to a competitor.

The software almost certainly has to be updated regularly, probably monthly, possibly weekly, which means that the algorithms and code are almost certainly obsolete, but still they want the court sealed.

This is not about protecting trade secrets, this is about concerns by the vampire squid* that if the details on how they conducted business came out, they would have people calling for their scalps for front-running the markets.

Basically, Goldman, and the prosecutors, are trying to conceal activity by Goldman that is either illegal, or would lead to changes in regulations that would make it so if the details came out.

My earlier posts on this are here.

*Alas, I cannot claim credit for the bon mot describing Goldman Sachs as a, “great vampire squid wrapped around the face of humanity, relentlessly jamming its blood funnel into anything that smells like money.” This was coined by the great Matt Taibbi, in his article on the massive criminal conspiracy investment firm, The Great American Bubble Machine.

Last weekend, the US Military lost control of a missile squadron:

President Obama was briefed this morning on an engineering power failure at F.E. Warren Air Force Base in Wyoming that took 50 nuclear intercontinental ballistic missiles (ICBMs), one-ninth of the U.S. missile stockpile, temporarily offline on Saturday.

The base is a main locus of the United States’ strategic nuclear forces. The 90th Missile Wing, headquartered there, controls 150 Minuteman III intercontinental ballistic nuclear missiles. They’re on full-time alert and are housed in a variety of bunkers across several states.

On Saturday morning, according to people briefed on what happened, a squadron of ICBMs suddenly dropped down into what’s known as “LF Down” status, meaning that the missileers in their bunkers could no longer communicate with the missiles themselves. LF Down status also means that various security protocols built into the missile delivery system, like intrusion alarms and warhead separation alarms, were offline. In LF Down status, the missiles are still technically launch-able, but they can only be controlled by an airborne command and control platform like the Boeing E-6 NAOC “Kneecap” aircraft, E-4B NAOC aircraft or perhaps the TACAMO fleet, which is primarily used to communicate with nuclear submarines. Had the country been placed on a higher state of nuclear alert, those platforms would be operating automatically because the frequencies used to transmit nuclear codes would be interfacing with separate systems, according to officials.

This is about 1⁄9 of our land based deterrent.

Great googly moogly.

Another Bit of Tech that I Worked With on FCS*

I’ll wait for reports from the field

The army is looking to deploy the XM25 25mm grenade launcher to Afghanistan.

The ‘special sauce” for this system is that the fire control system on the round can set the round to detonate at a specific distance, so you can set it to detonate past the cover an opponent is using for protection.

The example here is to put a round through a window, where it is set to detonate 2m beyond the building facade, which will certainly spoil that guy’s day.

This was intended to be used on the FCS-RMV in the full auto and remote controlled XM307 Advanced Crew Served Weapon where it would take the place of a crew served machine gun.

Truth be told, it strikes me as a little complex to function well in the confusion and grit and grime of battle, we should be hearing reports in the next few months.

*Full disclosure, I worked on the Future Recovery and Maintenance Vehicle, FRMV, “wrecker” variant of the FCS-MGV† from 2003-2006 at United Defense (later BAE Systems after the Carlyle Group sold me to buy Dunkin Donuts).
†Future Combat Systems-Manned Ground Vehicle. These are the ones that are the tanks and APCs. As opposed to the various unnmanned vehicles, networking technologies, etc. that form the full FCS along with the MGVs.‡

X2 Raider Mockup


The X-2 Raider, blissfully music free

Graham Warwick gives a survey of new technologies that might find their way into the Joint Multi Role (JMR) rotorcraft program, along with the video of the X-2’s record breaking flight (top)

Meanwhile, EADS is flight testing its X3 (I wonder where they got that name) compound helo, which uses dual wingtip props, and it provides anti-torque by varying the pitch of the thrusters.

It’s far less ambitious than that of the X-2, but their selling point is reduced life cycle cost, which is probably more a shot at the expensive tilt-rotors out there than the X-2 advancing blade concept, which really doesn’t seem particularly different in the amount of bits that move.

One interesting twist is that the X3 will slow its rotor at higher speed, reducing drag, though I could see this added to an advancing blade helicopter as well, particularly if the aircraft has a wing.

My quick look at the demonstrator indicates that it is not a particularly useful helicopter.

With two props about a yard from where the entrance to the passenger/cargo area is, both loading and unload, as well as the use of a winch for a rescue mission, would appear to me to be highly problematic.

Of course, the X3 is a demonstrator cobbled together with bits of various existing helicopters, so an operational version would likely address these shortcomings.

Sikorsky is also pitching a replacement for the OH-58D, theS-97 X2 Raider, which is rather similar to the MI-24 Hind or the Augusta/Westland Lynx concepts for an attack helicopter which retains transport capabilities or the ability to carry its own reloads.

Lockheed’s Concept

A tailless design for a transport, what the f%$# are they smoking


How stealthy will anything be with debris regularly cutting grooves in the skin?

If they are serious about their proposal for a stealthy transport roughly the size of a C-130, the answer is yes.

It’s entirely possible to design a STOL aircraft of C-130 or A-400M size that can cruise at conventional jet transport speeds, i.e. more than Mach 0.7 and take off or land in less then 200 feet.

In fact, the A400M comes awfully close to meeting those requirements right now cruising at almost Mach 0.7 with a takeoff and landing distance of about 2500 feet.

That being said, the idea that you want to do all of this, and then triple (at least) the lifetime costs of the airframe by making it stealthy is simply deluded.

While reducing the vulnerability of cargo aircraft to shoulder launched MANPADS is a good idea, experience has shown that the threats are primarily that and small arms fire, the idea that you need to create a reduced radar cross section, as appears to be the case with all (the tailless design is a Northrop-Grumman concept) is really bizarre.

If the enemy has air-superiority in the region, you are simply f%$#ed, and if they are in a position to have radar guided SAMs near your bases, you are, again, simply f%$#ed.

I’m with what Bill Sweetman wrote in the comments:

Everyone, but everyone, writing future airlift requirements for the USAF and US Army is secretly working for Airbus Military. Other than the massive abuse of chemicals there is no alternative explanation for this malarkey.

Bad Ideas Revisited

The Royal Navy has a problem, which is that with a typical weapons load in a tropical environment, the F-35B STOVL variant of the JSF cannot land without jettisoning some of its (very expensive) stores.

Their solution is the Shipboard Rolling Vertical Landing, for which the Royal Navy has just paid Lockheed $18 million for a viability study, in which the F-35 will land on a carrier deck in a combined wing borne and thrust borne mode, at about 60 kts airspeed without benefit of arrester gear.

So, you have an aircraft weighing something north of 35,000 pounds, which is going to hit the deck at 60+ kts, though the relative speed will likely be closer to 30 kts, and it will then be manually braked to a stop.

What a bloody mess.

European missile conglomerate MDBA has announced a successful test of its, “Hard and Deeply Buried Target (HARDBUT) Next Generation Multiple Warhead System (NGMWS).

It appears to be rather different in concept from the penetrators developed by the US, which use mass, metallurgy (ES-1 Steel), and specialized geometry to achieve a target kill. Hardbut appears to rely on a tandem warhead to achieve its goals:

The firing was carried out using a representative missile airframe on the long rocket sled test track at Biscarrosse. The live Precursor Charge (PC) was detonated just in front of the massive concrete target and the inert Follow-Through Bomb (FTB) penetrated through and exited the rear face of the target, demonstrating a penetration capability significantly in excess of any warhead currently produced by MBDA. The trial was also designed to assess the robustness of the compact Ruggedized Electronic In-line Fuze (REIF) which will incorporate embedded smart fuzing algorithms. The target and trial set-up were designed to be operationally representative.

(emphasis mine)

So it appears to me that there is a (probably shaped) charge, with a penetrator that follows behind.

H/t Danger Room.

Here is Some Sanity in Defense Procurement

The successor to the over-ambitious Future Combat Systems Manned Ground Vehicle (FCS-MGV)* the Ground Combat Vehicle (GCV) has now dropped many of the technologies intended for the FCS-MGV, because, even now, 2 years after the cancellation of the program, the programs are still insufficiently mature to be deployed on a combat system:

In an effort to make use of the billions of dollars it invested in the Future Combat Systems (FCS) program, the U.S. Army may have required too many immature technologies in its first Ground Combat Vehicle (GCV) Request for Proposals, according to the Army’s vice chief.

“We wanted to look and ensure that we made use of the investment in FCS and that we had the ability to use those technologies,” Gen. Peter Chiarelli told reporters at a Sept. 22 lunch in Washington.

However, if you want a vehicle in seven years, “you can’t be reaching deep for technologies right now,” he said.

………

According to Chiarelli, FCS was canceled in a way so that the Army could still make use of the research and development work done under the program.

“We wanted to ensure that those technologies that we worked so hard to develop could be integrated in to a new ground combat vehicle,” he said.

However, “there were a lot of those technologies that aren’t at a technology readiness level today where we could integrate them in seven years.”

(emphasis mine)

It boggles the mind that the technologies, “aren’t at a technology readiness level,” when the original intent was to begin fielding the FCS in 2008.

So the technologies in question won’t be ready 9 years after they were supposed to be fielded.

Our defense procurement system is seriously broken.

Describing the Green Party to a T

In Illinois the Green Party Candidate for Governor, Rich Whitney, had his name misspelled on voting machines. It reads Rich Whitey.

I know that there are “people of color” in the Green Party. The late Ed Boyd, an African American, ran for governor in Maryland in 2006, but received no party support, because they were focusing on (equally doomed) the Senate candidacy of rich whitey Kevin Zeese.

Ed Boyd was kind of pissed, but that really is how the Green Party rolls. It’s the comfortable pretending to afflict the comfortable.

At least, there is symmetry.

Zathras is used to being beast of burden to other people’s needs. Very sad life. Probably have very sad death. But…

but I think that God has a sick sense of humor,
and when I die, I expect to find him laughing:

In a bizarre twist, James Heselden, owner of the company that makes the two-wheeled Segway personal transporter, died Sunday morning in a Segway-related mishap — just before the scheduled release of a study suggesting injuries related to the vehicles may be on the rise.

According to a witness report, Heselden, 62, apparently fell off a 30-foot cliff into a river while riding a Segway near his home in West Yorkshire, UK. Police found Heselden’s body and a Segway personal transporter in the river. He was prounced dead at the scene and foul play is not suspected, West Yorkshire Police told reporters.

A short statement posted on the Segway company website noted that Heselden “died in a tragic accident.”

I think that I have commented before on the tremendous suckitude that is the Segway, and I do understand that this is a deep personal life for Heselden’s family, but this is just plain freaky.

F-35 Full Monty

Such a tease!

Stephen Trimble gives us a shot of the internal weapons bay of the F-35.

This is intended to be the standard loadout, with one AMRAAM and one 2000 lb JDAM in each bay.

IIRC, with the 250 lb SDB, it can carry 4 per bay.

And yes, this appears to be a pretty small weapons load for an aircraft that has a maximum takeoff weight of 70,000 pounds, nearly that of the F-15 E, which can carry about 5 times the ordinance.

Sikorsky X2 Sets Unofficial Speed Record

No Comments

The helicopter has reached speeds in excess of 250 kt (460 km/h) in level flight, besting the official record of 217 kts set by a (then Westland) Lynx, and the unofficial record set by its predecessor, the XH-59A demonstrator, of 236 kts.

It also appears that it could achieve a speed of 265 kts with the addition of a “sail fairing” between the two rotors.

It’s unclear to me, however how this is a helicopter speed record, and not a compound helicopter speed record, since the tail thruster makes a significant difference in just how power is applied at higher speeds.

I was under the impression that either a wing or a horizontal thruster made it a compound helo, but it appears that the definition being used here is that it’s specifically the wing that makes it a compound helicopter.

French Armed Forces Chief of Staff Agrees With Captain Kirk

1 Comment

You can find the full episode, Taste of Armegeddon, on Youtube, but here is Seth MacFarlane doing William Shatner

In a speech, he is suggesting that the extensive use of remotely controlled vehicles in the pursuit of war creates a sanitized war that could become immoral:

Admiral Edouard Guillaud, the French armed forces chief of staff, warned his distinguished audience at the Summer Defense University on September 14 that “there needs to be a fundamental reflection on the idea that there can be zero deaths in war.” Speaking in measured tones Guillaud, who could easily pass for a brilliant university professor, questioned the increasing use of armed unmanned air vehicles (UAVs) in Afghanistan. “War becomes banal when the aggressor runs no risks,” he said adding that “the growth in technology must slow down because man must be able to master it.” He stressed that this issue of man mastering technology or allowing himself to become a slave to it “is a real question.” He said “this is an ethical question which will eventually lead to some form of legislation.”

It does sound a lot like:

“Death… destruction, disease, horror, that’s what war is all about. That’s what makes it a thing to be avoided. You’ve made it neat and painless. So neat and painless, you’ve had no reason to stop it. And you’ve had it for over five hundred years. Since it seems to be the only way I can save my crew, and my ship, I’m going to end it for you. One way, or another.”

Obviously, it’s not immoral to make war in a manner that minimizes casualties, but it’s equally obvious that if the technology results in making war that one would not otherwise make, then there needs to be some real discussion of the what the idea of remote control war, run by remote control, makes war too much of a throw away decision.

White Spaces Passes FCC

White Spaces at a Glance:
“A” can use 400 MHz without interfering with anyone

Which means that it’s now official, and any number of high speed wireless devices will be able to operate without a license in the spaces between TV channels:

The Federal Communications Commission today unanimously approved new rules for the use of unlicensed white space spectrum in a move that could pave the way for more unused wireless spectrum to be released in the future.

White space is unused spectrum that sits between TV channels. The 300MHz to 400MHz of unused spectrum is considered prime spectrum for offering wireless broadband services because it can travel long distances and penetrate through walls. The FCC unanimously agreed in November 2008 to open up this spectrum for unlicensed use. Even so, technical issues to allow device makers and service providers to use the spectrum still need to be worked out.

(emphasis mine)

The technical issues are a big deal, because, as the redoubtable Harold Feld notes, the devil is really in the details here, and the incumbent wireless providers want to require that devices ping themselves to death:

Right now, the rules require a Mode 2 (the ones that access the database directly) to ping the database every 24 hours. Mode 1 devices “listen” to Mode 2, according to the 2008 Order (which I understand means “get told when an actual change occurs). The broadcasters want the Mode 1 devices to ping the Mode 2s every 60 seconds and want Mode 2 to ping the database every 15 minutes, if not more frequently. Since television broadcast towers are big stationary things, not Ents marching on Isengard, one may ask why devices need to check more than once a day. In response, broadcasters explain that if some day some news team somewhere they might possibly be running down the street after some hot news lead if they ran into someone using a smart phone with white spaces capability it might, possibly, cause some sort of interference with the mobile news crew’s wireless microphone system.

At this time, it appears that they did not go with the ping of death regulations, nor did they require “Sense and Avoid” technology, which is purported to be both expensive and technically challenging.

One of the big things here is the geographical database: If the TV stations start making bogus claims of interference, we may end up with a situation where the coverage will be limited to remote rural areas.

FCC Finally Approves White Spaces

No Comments

Basically, the FCC will be developing standard for unlicensed spectrum used on the spaces between TV channels to create a sort of super WiFi, using what is called “Sense and Avoid” technology.

It’s taken a long time to get here, largely because two groups, the broadcasters who wanted to be paid for something they didn’t have a license for and never used, they claimed interference issues, and the users and manufacturers of many wireless microphones, who had been using the spectrum illegally for years.

Technically, it is a good range of spectrum, it’s the analogue TV spectrum, so it goes a decent distance and penetrates walls and basements well, but more important is that it is unlicensed, which means that the use of the spectrum will be highly competitive, because, unlike wire, or the spectrum owned by wireless telcos, anyone can supply a service, as long as it complies with the technical requirements.

“Unlicensed” here means that anyone can operate the equipment, but that the equipment itself would have to be approved by the FCC before a sale is made.

This has a real potential to compete with the incumbents, and the barriers to providing service are low enough that there should be a fair number of entrants.
