'''Darts''' are airborne ranged [[ranged weapon]]s. They are designed to fly such that a sharp, often weighted point will strike first. They can be distinguished from [[Javelin (weapon)|javelin]]s by the presence of [[fletching]] (feathers on the tail) and a shaft that is shorter and/or more flexible. Darts can be propelled by hand or with the aid of a hand-held implement, theysuch as a [[blowgun]]. They can be distinguished from [[arrow]]s because they are too short to benot used inwith a [[Bow (weapon)and arrow|bow]].
 
Darts have been used since pre-history. The [[plumbatae]] were lead-weighted darts thrown by infantrymen in Antiquity and the Middle Ages. Darts can be propelled by a number of means. The [[atlatl]] uses leverage to increase the velocity of the dart, the [[kestros (weapon)|kestros]] increases the range of propelled darts using a sling, and smallthe poisonedexhalation needlesof thata areperson's propelledbreath withthrough pneumatica forceblowgun frompropels thesmall exhalationstone ofpoints aor person'spoisoned breathneedles with apneumatic [[blowgun]]force.
 
In the modern era, darts have been used for recreation; in [[lawn darts]] and the game of [[darts]].
 
==History==
===Pre-history===
[[Image:Nativo do Novo Mundo lançando flecha com o propulsor ou estólica.pdf|thumb| A dart being propelled by an [[Atlatlatlatl]]]]
Some of the earliest evidence of advanced tool use includes remnants of an early type of dart, which can be considered the ancestor of arrows as well as bows. Reconstructions of this system have a range of over one hundred metres (yards) and can penetrate several centimetres of oak. This technology was used worldwide from the Upper [[Palaeolithic]] (late Solutrean, c. 18,000–16,000 BC) until the development of [[archery]] made it obsolete.
 
Line 20:
Its similarity to a bow may not be immediately obvious, but in fact both serve to accumulate [[energy]] by [[Elasticity (physics)|elasticity]] in a similar way. As throwing begins, a dart of this type is designed to flex in compression between the accelerating force at its nock and the [[inertia]] of its weighted point, storing energy. Late in this throw, as the point moves faster and so offers less resistance, the dart releases most of this energy by springing away from the thrower. Some energy may also be recovered by the fletching as the projectile "fishtails" through the air. However, this energy is far less than is commonly stated and only effectively increases accuracy by counteracting the downward force on the tail.
 
To maximize elastic energy storage and recovery, such darts should be held only by the nock and allowed to pivot as they are thrown. This requires a special tool called a [[spear-thrower]]. In Western culture these might be called ''[[atlatl]]'' borrowed from the [[Aztec]], or in Australia the Aboriginal word [[Woomera (spear-thrower)|''woomera'']] is used.

Archery may be easier to learn and have a faster rate of fire, yet perhaps this system's greatest advantage over the spear-thrower is that ammunition is easier to make and transport. Since the dart must store almost all of the system's elastic energy, more care, planning, and weight of elastic material must be invested in its construction. In archery, the bulk of elastic energy is stored in the throwing device, rather than the projectile; arrow shafts can therefore be much smaller, and have looser [[tolerance (engineering)|tolerance]]s for [[spring (device)|spring]] constant and weight distribution than spear-thrower darts. For example, stone dart points from the same set tend to vary in mass by no more than a few percent, and computer simulations show that this is necessary for efficient operation. Similar constraints exist for the length, diameter, and materials quality of the shaft. If the same amount of attention and material are instead invested into a bow, projectiles can be made lighter (by a factor of five or more) and to less exacting [[tolerance (engineering)|tolerances]]. This allowed for more forgiving [[flint (tool)|flint]] knapping.

===Reconstructions===
Darts, [[plumbata]] and atlatls have been constructed by modern enthusiasts, either with ancient materials and methods or with high technology borrowed from modern archery. While some do this in the context of [[anthropology]] or [[mechanical engineering]], many view the practice as a [[sport]], and throw competitively for distance and/or for accuracy. Throws of almost {{convert|260|m|ft|abbr=on}} have been recorded.<ref>{{Cite web|url=https://www.flight-toys.com/atlatl.html|title=atlatlAtlatl - resource web page for a primitive hunting tool that predates the bow and arrow|website=www.flight-toys.com}}</ref>
 
==Types of traditional darts==
Line 49 ⟶ 51:
 
===Thrown darts===
It is quite reasonable to speculate the darts used with ''atlatl''s were adapted from hand-thrown darts{{speculation inline|date=April 2023}}, which in turn were derived from light javelins. In Europe, short but heavy-pointed darts were sometimes used in warfare. These had a length of about {{convert|30|toand|60|cm|ft|abbr=on}} and resembled an arrow with a long head and short shaft.
 
The Roman model, the ''[[plumbata]]'', was weighted with lead.<ref>For an image of a plumbata (without its wooden shaft, which did not survive the passage of time) and other projectiles see http://www.romancoins.info/MilitaryEquipment-spear.html</ref> In some legions, five of these were carried inside each soldier's shield; reconstructions show a range of {{convert|70|m|yd|abbr=on}} or more when thrown overhand in the fashion of a [[Stielhandgranate|German stick grenade]].
 
===Feathered darts===

Feathered spears, often called darts or javelins, were used in medieval and Renaissance Europe, both as ceremonial objects and as weapons. It is possible no examples have survived, presumably due to their fragility or the deterioration of their [[fletching]] making them indistinguishable from spears, but they appear in multiple illustrations from the 15th and 16th century. As ceremonial items, they are shown held similar to scepters by military commanders and leaders such as [[Emperor Maximilian I]].<ref name=Nikel>{{Cite journal | title = Ceremonial Arrowheads from Bohemia | author = Nikel, Helmut | workjournal = Metropolitan Museum Journal | publisher = The Metropolitan Museum of Art | volume = 1 | pagepages = 78-8178–81 | date = 1968 | access-date = 2018-01-03 | url = https://www.metmuseum.org/art/metpublications/ceremonial_arrowheads_from_bohemia_the_metropolitan_museum_journal_v_1_1968}}</ref><ref name="Waldman 2005">{{cite book | last=Waldman | first=John | title=Hafted weapons in medieval and Renaissance Europe the evolution of European staff weapons between 1200 and 1650 | publisher=Brill | location=Boston | year=2005 | isbn=90-04-14409-9 | pages=81–83}}</ref> Many other illustrations show large darts being wielded as weapons, either on the battlefield or in smaller engagements such as judicial battles.<ref name="Waldman 2005"/> Depictions show them as being four to seven feet long, with arrow-like feather [[fletching]], barbed points and thick shafts comparable to conventional [[polearms]], presumably able to serve for both throwing and hand-held striking.

===Kestros===

Of the darts still in widespread use, perhaps the closest to traditional thrown darts are [[lawn darts]].

An indoor game of [[darts]] has also been developed.

[[Tranquillizer gun|Tranquilizer dart]]s are related to the darts for blowguns, but include a [[hypodermic needle]] and a hollow reservoir resembling a [[syringe]], which is generally filled with [[sedative]]s or other drugs. These are launched from a [[dart gun]] using compressed gas, a tuft of fibers at the back of the missile serving as both [[fletching]] and [[wadding]].
 
A type of dart still finds use in military engagements, in the form of [[flechette]]s. These are all-metal projectiles, often resembling nails that have had fletching (rather than nail heads) forged into them. They were used by American forces during the wars in [[Korean warWar|Korea]] and [[Vietnam warWar|Vietnam]], but treaties have since been enacted to limit their use.
 
Large flechettes are used as [[kinetic energy penetrator]]s in many gun-fired [[anti-tank weapon|anti-armour]] projectiles.
