'''Darts''' are airborne
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

===Pre-history===
[[Image:Nativo do Novo Mundo lançando flecha com o propulsor ou estólica.pdf|thumb| A dart being propelled by an [[
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

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.

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|

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 |

Some later artistic depictions suggest they may have also been used for hunting.<ref>[[Nicholas Penny|Penny, Nicholas]], National Gallery Catalogues (new series): ''The Sixteenth Century Italian Paintings, Volume II, Venice 1540–1600'', p. 278, 2008, National Gallery Publications Ltd, {{ISBN|1857099133}}.

Of the darts still in widespread use, perhaps the closest to traditional thrown darts are [[lawn darts]]. These are large and heavy enough to be thrown by swinging, and to seriously wound a person when thrown.<ref>{{cite web | url=http://www.cpsc.gov/CPSCPUB/PREREL/PRHTML97/97122.html | title=Lawn Darts Are Banned and Should Be Destroyed | access-date=2019-08-29 | date=1997-05-15 | publisher=U.S. Consumer Product Safety Commission | quote=Lawn darts can cause skull punctures and other serious injuries.| url-status=dead | archive-url=https://web.archive.org/web/20101216065043/http://cpsc.gov/cpscpub/prerel/prhtml97/97122.html | archive-date=2010-12-16 }}</ref>

[[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
Large flechettes are used as [[kinetic energy penetrator]]s in many gun-fired [[anti-tank weapon|anti-armour]] projectiles.
