Fuerzas Sutiles
''Fuerzas sutiles'' ("subtle forces") was an 18th century term, used in the Spanish Empire and its successor states, referring to the strategic usage of small vessels in naval warfare.Martínez-Valverde, 1992 This included gunboats, xebecs and armed feluccas, originally used to defend ports before being re-purposed to offensive tactics, escorting convoys and operate in seas and rivers. The concept was popularized by captain Antonio Barceló, after which the Spanish Armada developed it extensively and with great efficacy, turning subtle forces into what has been described as "sea guerrillas". This kind of naval warfare would be known in France as ''flotilles a l’espagnole'' ("Spanish-style flotillas"). Vessels and tactics Traditional nomenclature in the Spanish Armada included four stages: ''buques de porte mayor'' ("major-sized ships" of over 34 guns, like ships of the line and frigates), ''buques de porte menor'' ("minor-sized ships" of 16 guns, like corvettes) and ''fuerza ...

Fire Ship
A fire ship or fireship is a large wooden vessel set on fire to be used against enemy ships during a ramming attack or similar maneuver. Fireships were used to great effect against wooden ships throughout naval military history up until the advent of metal-hulled ships; they could also serve a considerable function in shock and awe strategies to harm the morale of enemy crews. Ships used for fireship tactics were typically purpose-built or retrofitted from surplus or obsolete vessels, either of which could be filled with gunpowder or other combustibles before a battle, but could also be improvised from warships in active combat purposely set on fire during engagements, such as if a vessel expended its munitions or had some other reason to be abandoned in battle. Specialized fire ships included the massive Dutch hellburners, also called "explosion ships", which were fitted with large explosive stores designed to detonate upon contact with the enemy. Fireships were used to gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supply Line
Military supply-chain management is a cross-functional approach to procuring, producing and delivering products and services for military materiel applications. Military supply chain management includes sub-suppliers, suppliers, internal information and funds flow. Terminology A supply involves the procurement, distribution, maintenance while in storage, and salvage of supplies, including the determination of kind and quantity of supplies. United States Department of Defense definitions refer to a "producer phase" and a "consumer phase": *the producer phase of a military supply extends from determination of procurement schedules to acceptance of finished supplies by the military services *the consumer phase of a military supply extends from receipt of finished supplies by the military services, through issue for use or consumption. A supply chain is a set of linked activities associated with providing material from a raw material stage to an end user as a finished good. S ...

Steamboat
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. The term ''steamboat'' is used to refer to small steam-powered vessels working on lakes, rivers, and in short-sea shipping. The development of the steamboat led to the larger steamship, which is a seaworthy and often ocean-going ship. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. Background Limitations of the Newcomen steam engine The first steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The heavy weight of the Newcomen engine required a structurally strong boat, and the reciprocating motion of the engine beam required a compli ...

Incendiary Ammunition
Incendiary ammunition is a type of ammunition that contains a chemical that, upon hitting a hard obstacle, has the characteristic of causing fire/setting flammable materials in the vicinity of the impact on fire. World War I The first time incendiary ammunition was widely used was in World War I, more specifically in 1916. At the time, phosphorus was the primary ingredient in the Incendiary device, incendiary charge and ignited upon firing, leaving a trail of blue smoke. These early forms were also known as "smoke tracers" because of this. Though deadly, the effective range of these bullets was only 350 yards (320 metre, m), as the phosphorus charge burned quickly. Incendiary bullets called "Buckingham" ammunition were supplied to early British night fighters for use against military zeppelins threatening the British Isles. The flammable hydrogen gas of the zeppelins made incendiary bullets much more deadly than standard ones which would pass through the outer skin without i ...

Howitzer
The howitzer () is an artillery weapon that falls between a cannon (or field gun) and a mortar. It is capable of both low angle fire like a field gun and high angle fire like a mortar, given the distinction between low and high angle fire breaks at 45 degrees or 800 mils (NATO). With their long-range capabilities, howitzers can be used to great effect in a battery formation with other artillery pieces, such as long-barreled guns, mortars, and rocket artillery. Howitzers were valued for their ability to fire explosive shells and incendiary materials into fortifications. Unlike mortars, which had fixed firing angles, howitzers could be fired at various angles, providing greater flexibility in combat. Throughout the 18th and 19th centuries, howitzers evolved to become more mobile and versatile. The introduction of rifling in the mid-19th century led to significant changes in howitzer design and usage. By the early 20th century, howitzers were classified into different categor ...

Cannon
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge (firearms), gauge, effective range, mobility (military), mobility, rate of fire, elevation (ballistics), angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. The earliest known depiction of cannons may have appeared in Science and technology of the Song dynasty#Gunpowder warfare, Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannons do ...

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Rowing
Rowing is the act of propelling a human-powered watercraft using the sweeping motions of oars to displace water and generate reactional propulsion. Rowing is functionally similar to paddling, but rowing requires oars to be mechanically attached to the boat, and the rower drives the oar like a lever, exerting force in the ''same'' direction as the boat's travel; while paddles are completely hand-held and have no attachment to the boat, and are driven like a cantilever, exerting force ''opposite'' to the intended direction of the boat. In some strict terminologies, using oars for propulsion may be termed either "pulling" or "rowing", with different definitions for each. Where these strict terminologies are used, the definitions are reversed depending on the context. On saltwater a "pulling boat" has each person working one oar on one side, alternating port and starboard along the length of the boat; whilst "rowing" means each person operates two oars, one on each side of ...

Lateen
A lateen (from French ''latine'', meaning "Latin") or latin-rig is a triangular sail set on a long Yard (sailing) , yard mounted at an angle on the mast (sailing) , mast, and running in a fore-and-aft direction. The Settee (sail), settee can be considered to be an associated type of the same overall category of sail. The lateen originated in the Mediterranean as early as the 2nd century AD, during Roman times, and became common there by the 5th century. The wider introduction of lateen rig at this time coincided with a reduction in the use of the Mediterranean square rig of the classical era. Since the performance of these two rigs is broadly similar, it is suggested that the change from one to the other was on cost grounds, since lateen rigs used fewer components and had less cordage to be replaced when it wore out. Arabs , Arab seafarers adopted the lateen rig at a later datethere is some limited archaeological evidence of lateen rig in the Indian Ocean in the 13th century AD ...

Galiot
A galiot, galliot or galiote, was a small galley boat propelled by sail or oars. There are three different types of naval galiots that sailed on different seas. A ''galiote'' was a type of French flat-bottom river boat or barge and also a flat-bottomed boat with a simple sail for transporting wine. Naval vessels * Mediterranean (16th–17th centuries) : Historically, a galiot was a type of ship with oars, also known as a half-galley, then, from the 17th century forward, a ship with sails and oars. As used by the Barbary pirates against the Republic of Venice, a galiot had two masts and about 16 pairs of oars. Warships of the type typically carried between two and ten cannons of small caliber, and between 50 and 150 men. It was a Barbary galiot, captained by Barbarossa I, that captured two Papal vessels in 1504. * North Sea (17th–19th centuries) : A galiot was a type of Dutch or German merchant ship of 20 to 400 tons ( bm), similar to a ketch, with a rounded fore and aft li ...

Galley
A galley is a type of ship optimised for propulsion by oars. Galleys were historically used for naval warfare, warfare, Maritime transport, trade, and piracy mostly in the seas surrounding Europe. It developed in the Mediterranean world during Classical antiquity, antiquity and continued to exist in various forms until the early 19th century. It typically had a long, slender hull, shallow draft (hull), draft, and often a low freeboard (nautical), freeboard. Most types of galleys also had sails that could be used in favourable winds, but they relied primarily on oars to move independently of winds and currents or in battle. The term "galley" originated from a Greek term for a small type of galley and came in use in English from about 1300. It has occasionally been used for unrelated vessels with similar military functions as galley but which were not Mediterranean in origin, such as medieval Scandinavian longships, 16th-century Ghali (ship), Acehnese ghalis and 18th-century North ...
