Giant Extruded Powder Sticks for Huge Naval Cannons

DuPont artillery naval powder cannon gun kernel propellant stick

Story by Boyd Allen
While many top competitive shooters trickle their stick powder charges to a kernel or two, that would be impractical when loading charges for giant naval guns. You may be surprised, but the shells fired by the U.S. Navy’s massive 14″ and 16″ naval guns were also propelled by stick-type extruded powders. You couldn’t trickle these ‘kernels’ though — a single stick or ‘grain’ can be over 2″ long.

The U.S.S. Iowa fires her massive 16″ main battery. The U.S. Navy’s Iowa-class battleships carried nine huge 16-inch Mark 7 cannons in three turrets. The big naval guns were 50 calibers long, i.e. 50 times bore diameter, making the barrels 66.7 feet long from chamber to muzzle.

In connection with a Benchrest Central discussion that drifted to the subject of powders used in large naval guns, I heard from Joe McNeil, whose father was involved in manufacturing those very propellants as a DuPont employee. Joe writes:

“My Dad worked for the DuPont company for over 40 years. Every time the nation went to war he was assigned to the gun powder plants which DuPont ran for the government for $1.00 per year! His last assignment was at the Indiana Ordnance Plant in Jefferson, Indiana from 1952 through 1958. He had a display case made of all of the different powders made at the plant and left it to me. That’s why I have a grain of 16″ gun powder. He took me out to the Jefferson proving grounds once when they tested the powder in a 16″ gun. We watched from a half-mile away but it left a lasting impression when they fired that gun. They actually had a set of rings they fired through to test the performance of the powder and shell. This was a truly fond memory of my Dad and his work.”

Here are some pictures of the gun powder “grains” made during the Korean War at the Indiana Ordnance Works where Joe McNeil’s father worked.

There are different-sized ‘grains’ for specific rounds.

Veterans Day — November 11th — Honor All Who Served

Memorial Veterans Day Vet Army Navy Marines WWII WWI

On that day, let us solemnly remember the sacrifices of all those who fought so valiantly, on the seas, in the air, and on foreign shores, to preserve our heritage of freedom, and let us reconsecrate ourselves to the task of promoting and enduring peace so that their efforts shall not have been in vain.

– 1954, President Dwight D. Eisenhower, Veterans Day proclamation.

105 Years Later…
On the 11th hour, of the 11th day, of the 11th month of 1918, bugle calls signaled the ‘cease fire’ ending the First World War. (The official Armistice was signed earlier that morning.) To those who endured it, WWI was the “Great War”, “the War to End All Wars.” Tragically, an even greater conflict consumed the world just two decades later.

Today, 104 years after the end of WWI, Americans mark the anniversary of the WWI Armistice as “Veterans Day”. In Canada it is known as Remembrance Day. On this solemn occasion we honor all those who have served in the military in times of war and peace.

Memorial Veterans Day Vet Army Navy Marines WWII

While more veterans pass away each year, there are still about 19 million veterans in the United States. Take time today to honor those soldiers, sailors, and airmen who have served their nation with pride. Today we remember that… “All gave some, and some gave all.” History of Veterans Day.

Memorial Veterans Day Vet Army Navy Marines WWII Pearl harbor

Former Secretary of Veterans Affairs Dr. James Peake asked Americans to recognize the nation’s 19 million living veterans and the generations before them who fought to protect freedom and democracy: “While our foremost thoughts are with those in distant war zones today, Veterans Day is an opportunity for Americans to pay their respects to all who answered the nation’s call to military service.”

On Veterans Day we especially need to remember the seriously wounded combat veterans. These men and women summon great courage every day to overcome the lasting injuries they suffered in battle. Some of these soldiers have lost limbs, yet volunteered to return to combat duty. That is dedication beyond measure — true patriotism.

Navy’s BAE Railgun Shoots Projectile 203 Kilometers at Mach 7

Navy BAE Railgun

How would you like to “reach out and touch” someone 203 kilometers away (about 110 nautical miles)? Well America’s Navy may soon be able to do exactly that with an amazing new, high-tech weapon system. BAE Systems has developed (and successfully test-fired) an electro-magnetic rail gun that fires a 23-lb projectile at Mach 7 — (about 5300 mph or 7800 fps). This futuristic weapon can send its projectile 110 nautical miles (126 mi / 203 km), five times the range of the big 16″ guns on WWII-era battleships. This railgun has serious “knock-down” power — at Mach 7, that projectile carries a whopping 32 megajoules of energy. BreakingDefense.com says: “23 pounds ain’t heavy. But it sure hurts when it hits you going at seven times the speed of sound.”

Watch Video to See Navy Rail-Gun in Action:

The latest prototype of the railgun developed by defense contractor BAE, in conjunction with the Office of Naval Research, can accelerate a projectile up to Mach 7 within 10 milliseconds. The gun uses no gunpowder to generate propelling force. Compared to an item on a smaller scale, the railgun projectiles resemble crossbow darts, except they deliver such massive Kinetic Energy they don’t need to carry explosive ordnance. The railgun can strike targets 110 nautical miles away.

To prepare a charge, the ship stores electricity in the pulsed power system. Next, an electric pulse is sent to the railgun, creating an electromagnetic force accelerating the projectile. Because of its extreme speed, the projectile eliminates the hazards of storing high explosives in the ship. Each shot costs about $25,000 — but that’s cheap compared to the price of a missile.

“It’s like a flux capacitor,” chief of Naval research Rear Admiral Mathias Winter said in a video posted by Reuters Friday. “You’re sitting here thinking about these next generation and futuristic ideas, and we’ve got scientists who have designed these, and it’s coming to life.”

The Electromagnetic Railgun Innovative Naval Prototype (INP) was initiated in 2005. The goal during Phase I was to produce a proof-of-concept demonstration at 32 mega-joule muzzle energy, develop launcher technology with adequate service life, develop reliable pulsed power technology, and assess component risk reduction for the projectile.

Navy BAE Railgun

Phase II, which started in 2012, advanced the technology to demonstrate a repeatable-rate fire capability. Thermal-management techniques required for sustained firing rates will be developed for both the launcher system and the pulsed power system. The railgun will begin testing at sea in 2016.

NRA Intercollegiate Pistol Championship Concludes

NCAA Pistol ChampionshipFrom March 15-19, the NRA Intercollegiate Pistol Championships were held at Ft. Benning, Georgia. The tournament determined the National Collegiate Individual and Team Champions in NTA Intercollegiate Free Pistol, Standard Pistol, Open Air Pistol, Women’s Air Pistol and Women’s Sport Pistol. Both men and women competed shoulder to shoulder in Free Pistol, Standard Pistol, and Open Air Pistol events, but there were separate Ladies’ Only matches for Air Pistol and Sport Pistol. Men and Women shooters competed in separate divisions.

Navy beats Army in Ladies’ Sport Pistol and Air Pistol
There was a strong rivalry among the military academy teams in the Women’s Pistol Matches at the USAMU’s 25 meter range. In Women’s Sport Pistol, the U.S. Naval Academy earned its second Women’s championship this year with a score of 1626, topping the West Pointers by 24 point. In the individual Sport Pistol finals, Kirsten Asdal of the U.S. States Naval Academy took the win with a 655.3 score, edging West Point’s Heather Deppe (653.9 score). The Lady Midshipmen (Midshipwomen?) also won the Women’s Air Pistol Championship with a final team score of 1086. Arch-rival West Point finished second with a 1073 team Air Pistol score.

U.S.M.A. (West Point) Win’s Standard Pistol Team Championship
USNA, USMA, Ohio St., Citadel, Oregon St., USCGA, MIT, Texas A&M, Yale and USMMA were all represented in the team championship by shilled shooter however after the third stage had been fired the United States Military Academy had emerged victorious with a total team score of 2121. Tallying up another championship under his belt this year, Nick Mowrer of Pikes Peak Community College shot a 569 to claim the Standard Pistol Individual title.
