Hotchkiss Model 1886 3-pounder Quick Firing Gun

Small fast boats with torpedos (or other explosives) have always been a threat to large warships. One of the weapons the British Royal Navy adopted to counter that threat was the Hotchkiss Model 1886 “Quick Fire” gun. This meant that it was a breech-loaded gun that used self-contained cartridge ammunition, instead of separate powder bags and projectiles. Mounted on a recoil-adsorbing soft mount with a wide range of movement and steep depression angle, guns like this could fire at small mobile torpedo boats that a capital ship’s main armament couldn’t handle.

This particular model is a 47mm bore, or 3-pounder as described in British service. It uses a vertically-traveling breech block, and more than 3,000 or them were acquired by the British. Two of them were employed as part of the Falkland Islands coastal defenses at one time. This example is one of two brought down from Gibraltar fairly recently and refurbished for ceremonial use on the Islands. Thanks to the FIDF for setting it up on its mount so I could film it for you!

  1. Further impetus to build the model quick firing gun, I’ve had the plans since you posted them way back and had actually just pulled them out to look over this past week.

  2. Well you can see why when bazookas got invented, folks thought; nice. “Big guns” well… Bigger, in regards this to a rifle, as oppose bigger guns, eh… Drones now, shells cheap’ish but all that steel needed to contain the BANG!!! I.e. Like a rifle, lessened – Bazookas; rocket lark. Recoiless rifles, drones. I think loitering drone muntions launched from wee blimps might prove, well sort of like floating “Prowling” mines – Nobody likes mines, with good reason. Sensors, so they just go to targets and swarm. Unsettling all this new “Mini airpower” really. Via batteries, battety tech, and little shitty leccy motors; that do the job. Floating helium double skin condoms with the trellis niti spriral inside breathing… With its wee drone “Piece of targeted” shrapnel inside. Brave new world really.

  3. The forerunner of pretty much all such “quick-firing” guns.

    The Williams gun was a Confederate gun that was classified as a 1-lb cannon. It was designed by Captain D.R. Williams, of Covington, Kentucky, who later served as an artillery captain with a battery of his design. It was a breech-loading, rapid-fire cannon that was operated by a hand-crank. The barrel was four feet long and a 1.57-inch caliber. The hand crank opened the sliding breech which allowed the crew to load a round and cap the primer. As the crank was continued, it closed the breech and automatically released the hammer. The effective range was 800 yards but the maximum range was 2000 yards.

    Approximately 40 were made, to supply seven different Confederate batteries. These were made at F. B. Deane Jr. & Son, Lynchburg, Virginia, Tredegar Iron Works, Richmond, Virginia, and Skates & Co, Mobile, Alabama. At the end of the war, four examples of this gun were captured to send to West Point. The West Point Museum retained one gun. Other examples are now located at the Kentucky Military History Museum the Virginia Museum of the Civil War at the New Market Battlefield State Historical Park, and the Watervliet Arsenal Museum.

    During the early trials of the gun, the Richmond Daily Exchange dated May 20, 1862, reported that: “General Floyd attended a trial of the Williams’ mounted breech-loading rifle, which is claimed will throw twenty balls a minute a distance of fifteen hundred yards”. Some sources say it could fire 65 rounds per minute but accuracy was greatly reduced due to the manual loading. The Union troops did not know what the gun was. Some describe it as a rifled cannon. Others reported that it fired nails, probably on account of the noise the projectile made as it tumbled.

    Thew Williams gun’s breech operated much like the shuttle in a loom.

    As the eccentric cam on the crank withdrew the breechblock, the loader shoved a linen cartridge containing projectile (solid shot or time-fused shell) and propellant powder into the breech and capped the nipple. When the crank completed the rotation, the breechblock was fully forward and the self-sprung hammer was released to strike the cap.

    While it could fire up to 60 R/M, that heated the breechblock up enough to cause it to expand and possibly hang up. Its rated maximum RoF was about 30 R/M, which is still pretty impressive by the standards of the day.

    While not really all that effective as a land service gun, it pointed the way to later naval anti-torpedo boat quick-firers.
