Navy dolphins discover Howell torpedo off Coronado

Tuesday, May 21st, 2013

Howell torpedoThe US Navy trains dolphins and sea lions to find mines — something I noted, good Lord, over a decade ago! — and recently some Navy dolphins discovered a Howell torpedo off Coronado:

Until recently only one Howell torpedo was known to exist, on display at the Naval Undersea Museum in Keyport, Wash. Now a second has been discovered, not far from the Hotel del Coronado.

Meant to be launched from above the water or submerged torpedo tubes, the Howell torpedo was made of brass, 11 feet long, driven by a 132-pound flywheel spun to 10,000 rpm before launch. It had a range of 400 yards and a speed of 25 knots.

As a kid, I never wondered what propelled a self-propelled torpedo. The Howell torpedo used a flywheel, like a toy car, while its more successful competitor, the Whitehead torpedo, used compressed air:

The result was a submarine weapon, the Minenschiff (mine ship), the first self-propelled torpedo, officially presented to the Austrian Imperial Naval commission on December 21, 1866.

Maintaining proper depth was a major problem in the early days but Whitehead introduced his “secret” in 1868 which overcame this. It was a mechanism consisting of a hydrostatic valve and pendulum that caused the torpedo’s hydroplanes to be adjusted so as to maintain a preset depth.

After the Austrian government decided to invest in the invention, Whitehead started the first torpedo factory in Fiume. In 1870, he improved the devices to travel up to approximately 1,000 yd (910 m) at a speed of up to 6 kn (11 km/h), and by 1881 the factory was exporting torpedoes to ten other countries. The torpedo was powered by compressed air and had an explosive charge of gun-cotton.[5] Whitehead went on to develop more efficient devices, demonstrating torpedoes capable of 18 kn (33 km/h) in 1876, 24 kn (44 km/h) in 1886, and, finally, 30 kn (56 km/h) in 1890.

Royal Navy representatives visited Fiume for a demonstration in late 1869, and in 1870 a batch of torpedoes was ordered. In 1871, the British Admiralty paid Whitehead £15,000 for certain of his developments and production started at the Royal Laboratories in Woolwich the following year.

This was the crazy steampunk era of rapidly changing naval technology.

This is what winning looks like

Friday, May 17th, 2013

This is what winning looks like, according to Vice‘s ironically named documentary on Afghanistan:

“Advising” impoverished nations backfires in predictable ways — a lesson we could have easily learned from Vietnam, or from Nationalist China.

Marines arrive at a base to find all the protective barriers sold off as scrap. Fuel, ammunition — anything really — “falls off a truck” on a regular basis. Police and soldiers force local kids to do their manual labor and hold civilians for ransom. And then there are the truly creepy crimes…

Watching the Afghans “fight” also drives home how much they love to pull the trigger with no idea who or what they’re shooting at. It’s no wonder they see small arms as ineffective and demand heavy weapons. Of course, wild shooting means (a) they don’t hit the “enemy”, who might only be our enemy, and (b) they get more ammo from us, and can sell off the spent casings.

Medieval Arrowheads

Thursday, May 9th, 2013

In his gift shop, Hector Cole offers this medieval arrowhead set:

Devizes swallowtail broadhead
This is a typical hunting broadhead used against large game such as deer or boar. It is designed to inflict the maximum damage to the animal through its long cutting edges causing massive haemorrhaging so that the animal will not run far after being shot. This head is based on the arrowhead in Devizes museum.

Small straight broadhead
This is also a typical hunting head of the period that was used on smaller game producing the same effect as the swallowtail broadhead.

Forked hunting head, Type 6
This hunting head was used against birds and small game. The forked shape of the head fulfils two purposes, a) When it hits a bird the rotating motion of the head tears into the feathers and brings the bird down if in flight, b) If you miss when shooting at small game the head prevents the arrow from burying itself in the long grass or undergrowth making it easy to locate.

London Museum type 16 war head
This head is based on the heads of this type in the London Museum collection and the Westminster arrow. It is a war head of the later medieval period used to pierce plate armour.

War bodkin long type 10
This war head is the most common of the medieval period. It was used against knights in plate armour and will penetrate armour up to two millimetres in thickness.

Needle bodkin type 7
This war head was developed to pierce mail with devastating results and was used against lightly armoured foot soldiers throughout the medieval period.

Forging a War Bodkin

Thursday, May 9th, 2013

Watching Hector Cole forge a war bodkin — an armor-piercing arrowhead — can be hypnotic:

The electric grinder ruined the effect a bit though.

(Hector Cole came up in the discussion about making Mordor’s economy work. That arrowhead, by the way, seemed to take a skilled smith maybe ten minutes to produce.)

Shooting the 1911 Pistol Fast

LASD Range

Wednesday, May 1st, 2013

This 1936 footage from the Los Angeles (County) Sheriff’s Department’s Biscailuz Range struck me as terribly old-timey — especially with the ragtime soundtrack — until they got to the Combat Range:

They were scoring named courses of fire, based on real-life scenarios, in points per second, long before IPSC formed in the 1970s.

6 Ways to Make a Better Argument for Gun Control

Monday, April 29th, 2013

Otherwise-leftist blogger Kontra lives in Virginia and owns guns.  Kontra offers gun-control Democrats 6 ways to make a better argument:

Allow me this humble suggestion: The best way to convince the American public that you’re not interested in taking guns away is to stop talking about taking guns away.

Firstly, when your politicians are asked, “Do you support state legislation to ban the manufacture, sale and possession of handguns?” as Obama was in his 1996 Senate campaign, you should never answer “Yes,” as Obama did. Publicly advocating a ban on all handguns is not the way to convince people that you’re not interested in banning guns. Furthermore, when you are campaigning for president, never say the phrase “I continue to support a [federal] ban on concealed carry,” as Obama did in 2004. This gives people the impression that your intention is to prevent the states from setting reasonable guidelines on who can defend themselves outside of their home.

If you then win the election, do not go on to fully support gun bans in two US cities — Chicago and D.C. — in which law-abiding citizens are disarmed, citing them as models for gun policy while trying to convince the rest of the country that you really aren’t interested in banning their guns. (Guess which two US cities you’re most likely to be killed by a gun in.)

It has become almost cliché for smirking Democrats to attempt to ridicule people like myself by crooning, “Obama wants to take our guns!” in a stereotyped hillbilly drawl — something particularly offensive to some folks here in the south — when in fact, Obama has said exactly that.

I Killed My Friend

Sunday, April 28th, 2013

Nothing in Bruce Holbert’s New York Times piece, I Killed My Friend, makes much sense. Here’s how it kicks off:

The summer before my sophomore year in high school, I moved into my father’s house. My father had remarried and the only unoccupied bedroom in his house was the gun room. Against one wall was a gun case he had built in high school, and beside it were two empty refrigerators stocked with rifles and hundreds of rounds of ammunition. My bed’s headboard resided against the other wall and, above it, a resigned-looking, marble-eyed, five-point mule deer’s head with a fedora on its antler rack.

The room had no windows, so the smell of gun oil filled my senses at least eight hours each day. It clung to my clothes like smoke, and like a smoker’s cigarettes, it became my smell. No one in my high school noticed. We all smelled like something: motorheads of motor oil, farm kids of wheat chaff and cow dung, athletes like footballs and grass, dopers like the other kind of grass.

I don’t think I’ve ever met anyone who smelled of gun oil or been any place that smelled of gun oil — unless someone literally just cleaned and oiled a gun. Gun shops don’t smell like gun oil. Gun ranges don’t smell like gun oil. (They do smell like burnt gun powder though.)

Anyway, here’s the meat of his story:

The driver, who worked with the county sheriff’s department, offered me his service revolver to examine. I turned the weapon onto its side, pointed it toward the door. The barrel, however, slipped when I shifted my grip to pull the hammer back, to make certain the chamber was empty, and turned the gun toward the driver’s seat. When I let the hammer fall, the cylinder must have rotated without my knowing. When I pulled the hammer back a second time it fired a live round.

Wait, what? I don’t even understand how he claims to have set off that live round, but let’s review the rules of gun safety:

  1. All guns are always loaded.
  2. Never let the muzzle cover anything you are not willing to destroy.
  3. Keep your finger off the trigger until your sights are on the target.
  4. Be sure of your target and what is beyond it.

Who hands a loaded gun over without unloading it and showing that it’s clear? Or even mentioning that it’s “hot”?  Who points a loaded gun anywhere near his buddy while he checks to see if it’s loaded? And who thumbs the hammer back?

Are we supposed to believe the gun went off without anyone pulling the trigger?

I suppose non-shooters are meant to read a story like that and conclude, see, it can happen to anyone who owns a gun! Um, no, not really.  Not like that.

Speed-Shooting the M1 Garand

PoliceOne’s Gun Control Survey

Thursday, April 18th, 2013

PoliceOne’s gun control survey of more than 15,000 verified law enforcement professionals reveals 11 key findings:

  1. Virtually all respondents (95 percent) say that a federal ban on manufacture and sale of ammunition magazines that hold more than 10 rounds would not reduce violent crime.
  2. The majority of respondents — 71 percent — say a federal ban on the manufacture and sale of some semi-automatics would have no effect on reducing violent crime.
  3. About 85 percent of officers say the passage of the White House’s currently proposed legislation would have a zero or negative effect on their safety, with just over 10 percent saying it would have a moderate or significantly positive effect.
  4. Seventy percent of respondents say they have a favorable or very favorable opinion of some law enforcement leaders’ public statements that they would not enforce more restrictive gun laws in their jurisdictions. Similarly, more than 61 percent said they would refuse to enforce such laws if they themselves were Chief or Sheriff.
  5. More than 28 percent of officers say having more permissive concealed carry policies for civilians would help most in preventing large scale shootings in public, followed by more aggressive institutionalization for mentally ill persons (about 19 percent) and more armed guards/paid security personnel (about 15 percent).
  6. The overwhelming majority (almost 90 percent) of officers believe that casualties would be decreased if armed citizens were present at the onset of an active-shooter incident.
  7. More than 80 percent of respondents support arming school teachers and administrators who willingly volunteer to train with firearms and carry one in the course of the job.
  8. More than four in five respondents (81 percent) say that gun-buyback programs are ineffective in reducing gun violence.
  9. More than half of respondents feel that increased punishment for obviously illegal gun sales could have a positive impact on reducing gun violence.
  10. When asked whether citizens should be required to complete a safety training class before being allowed to buy a gun, about 43 percent of officers say it should not be required. About 42 percent say it should be required for all weapons, with the remainder favoring training classes for certain weapons.
  11. While some officers say gun violence in the United States stems from violent movies and video games (14 percent), early release and short sentencing for violent offenders (14 percent) and poor identification/treatments of mentally-ill individuals (10 percent), the majority (38 percent) blame a decline in parenting and family values.

Laser Shield

Thursday, April 11th, 2013

While the Pentagon is busy developing laser weapons, a small California company claims it has discovered a type of plastic that acts as armor against lasers:

Mr. Harlamor’s company developed the material, now trademarked “Laser Shield,” while searching for a plastic that could be shaped by machine tools yet withstand the stress of aerospace applications.

Researchers first knew they had something unusual when they tried to inscribe the new machinable plastic with an industrial laser-marking system. After 10 passes with this relatively low-power laser, the plastic was unscarred.

“There was no penetration,” confirms Gerhard Marcinkowski, sales manager of A-B Lasers, which carried out the marking test.

Laser Shield’s internal structure apparently acts as if it were made up of many tiny lenses. These internal “lenses” can scatter laser energy in a harmless, diffuse pattern.

Navy’s New Laser Cannon

Tuesday, April 9th, 2013

In tests aboard the destroyer USS Dewey, the Laser Weapon System successfully shot down surveillance drones and fast boats:

The tubular Laser Weapon System (LaWS) is a solid-state laser that’s been in development for six years, at a cost of $40 million. It’s a directed-energy descendent of the the radar-guided Close In Weapons System (CIWS; it rhymes with “Gee Whiz”) gun already aboard surface ships. In December, following the successful Dewey tests, Greenert ordered the laser “out to the fleet for an operational demonstration,” said Rear Adm. Matthew Klunder, the Navy’s chief of research. And so next year, LaWS will have its trial by fire, when the Navy puts it on the deck of its new afloat staging base USS Ponce for its maiden voyage to the Middle East.

It just so happens that the LaWS’ ability to track and kill surveillance drones and swarming fast boats matches with Iran’s development of surveillance drones and swarming fast-boat tactics. And it just so happens that the Ponce will spend most of 2014 deployed in Iran’s backyard.

[...]

The Navy won’t say just how many kilowatts of energy the LaWS’ beam is, but it’s probably under the 100 kilowatts generally considered militarily mature. The fact that LaWS can kill a surveillance drone and a fast-attack boat has more to do with the vulnerabilities of those systems than it its own prowess. It cannot stop an anti-ship missile, and its beam, about the circumference of a dime, will do little more than singe a fighter jet. And there remain significant challenges with cooling a shipboard high-energy laser, a necessary safety feature.

Ponce? Really?

Words from a Bosnian Survivalist

Monday, April 1st, 2013

These chilling words from a Bosnian survivalist remind us how bad things can get — almost overnight:

I am from Bosnia. You know, between 1992 and 1995 it was hell. For one year I lived, and survived, in a city with 6000 people, without water, electricity, gasoline, medical help, civil defense, distribution service, any kind of traditional service or centralized rule.

Our city was blockaded by the army and for 1 year life in the city turned into total crap. We had no army, no police, we only had armed groups — those armed protected their homes and families.

When it all started some of us were better prepared, but most of the neighbors families had enough food only for a few days. Some had pistols, a few had AK47s (  ) or shotguns.

After a month or two gangs started operating, destroying everything. Hospitals, for example, turned into slaughterhouses. There was no more police. About 80% of the hospital staff were gone. I got lucky — my family at the time was fairly large (15 people in a large house, 6 pistols, 3 Aks), and we survived (most of us, at least).

The Americans dropped MREs every 10 days, to help blockaded cities. This was never enough. Some — very few — had gardens. It took 3 months for the first rumors to spread of men dying from hunger and cold. We removed all the doors, the window frames from abandoned houses, ripped up the floors and burned the furniture for heat. Many died from diseases, especially from the water (two from my own family). We drank mostly rainwater, ate pigeons and even rats.

Money soon became worthless. We returned to an exchange. For a tin can of tushonka you could have a woman (it is hard to speak of it, but it is true). Most of the women who sold themselves were desperate mothers.

Arms, ammunition, candles, lighters, antibiotics, gasoline, batteries and food. We fought for these things like animals. In these situations it all changes. Men become monsters. It was disgusting.

Strength was in numbers. A man living a lone getting killed and robbed would be just a matter of time, even if he was armed.

Today me and my family are well-prepared, I am well-armed. I have experience.
