-->--''Film/StarTrekVITheUndiscoveredCountry'', on dealing with the invisible enemy ship

A projectile or attack in interactive media (or a narrative description in non-interactive media) that homes in on its intended target. If you're firing it, it can be an effective means of eliminating targets without putting yourself in harm's way. If an enemy is firing it, you'll need to perform a HighSpeedMissileDodge, [[LuckilyMyShieldWillProtectMe whip out a shield]], [[MisguidedMissile trick its guidance system]], ShootTheBullet [[DestructibleProjectiles if it is destructible]], or [[MundaneSolution just outrun it until it loses steam]].

A curious trait of most homing attacks is their inability to [[LeadTheTarget "lead" a moving target]], resulting in them doggedly "trailing" behind if the target can move fast enough. Very few homing attacks will actually plot an intercept course on a moving target.

A fairly common projectile type in [[ShootEmUp Shoot 'em Ups]] and TableTopGames.

Compare and Contrast with PlayerGuidedMissile. See also FlyingWeapon, which has a tendency to chase after the target.

Subtropes include:
* ActionBomb, in which the projectile in question doesn’t fly.
* BoomerangComeback, in which the projectile starts homing after overtaking the target...
** PrecisionGuidedBoomerang ...no matter what.
* HomingBoulders, in which the mechanic is there but doesn't make sense for the situation, such as boulders rolling at you that home in on your location.
* HomingLasers, in which the homing "projectile" in question is a laser beam.
* MacrossMissileMassacre, in which a huge, ominous cloud of homing missiles is released.
* MagicMissileStorm, a swarm of ProjectileSpell.
* {{Roboteching}}, in which the projectiles don't start homing until after they've flown a fair distance.
* PinballProjectile, in which the projectiles move by bouncing off of non-targets.
** ReflectingLaser ...even if the projectile is a laser beam.
* SuperPersistentMissile, in which the projectile not only guides itself toward a target but doesn’t give up if it misses. Can overlap with AlwaysAccurateAttack.



[[folder:Anime and Manga]]
* ''Anime/WolfsRain'': the Noble's have access to laser weapons that home in on their targets, inexplicably.
* ''Manga/{{Hellsing}}'': Rip Van Winkle has a rifle that shoots magic bullets that can immediately home on a target or do very fancy {{Roboteching}}.
* ''Anime/DragonBallZ'': Goku (Kamehameha twin dragon shot), Krillin (Double Tsuihikidan), and Piccolo (Chasing Bullet) have all used homing Ki attacks at one time or another.
** Android 13's [[SphereOfDestruction S.S. Deadly Bomber]] takes this even further, as the energy ball is seen making sharp ninty-degree turns in its flight path to track its victim.
* ''Manga/OnePiece''. Nami's Thunder Breed Tempo (a homing lightning bolt). In a CrowningMomentOfFunny, Franky also claims that his shoulder cannons do this, but subverts it when it's really just himself running after the opponent.
** Vander Decken IX ate the Mark Mark fruit, which allows him to "remember" one person per hand. If he then throws something with that same hand, he can make it chase the target until it hits or it's stopped. "Something" includes letters, arrows, giant axes, other people, [[spoiler:[[ColonyDrop a ship half the size of an island]]]]...
* ''Manga/{{Toriko}}''. Toriko can do this with his Flying Forks and Knives by using his [[TheNoseKnows sense of smell]] to track the targets scent.

* ComicBook/{{Darkseid}} whose omega beams take great pains to hit their target.

[[folder:Fan Works]]
* ''Plan 7 of 9 from Outer Space''. An ArmsDealer shows off a smartgun that's so smart, the bullets can track down a target at any range by disguising themselves as a member of the [[IntimidatingRevenueService Internal Revenue Service]].

* ''Film/{{Runaway}}'': A gun is introduced that fires projectiles that act like a tiny guided missiles, homing in on an individual's thermal signature.
* The same thing happens in ''Film/BabylonAD'', with the missile homing in on the nanite-passport injected in the protagonist's neck.
* ''Film/StarTrekVITheUndiscoveredCountry'': While most torpedoes are guided, and therefore should be guided InSpace, this movie had a particular torpedo that was explicitly seen to track a cloaked Klingon ship's ion trail.
* ''Film/XMenDaysOfFuturePast''. Magneto uses his powers to send a bullet arching out the window after Mystique, hitting her in the leg as she's falling ([[FridgeLogic how would he know her position though, if she wasn't in his line-of-sight?]]) He's also accused of [[MagicBullets doing this during the Kennedy assassination]], though [[WhoShotJFK Magneto denies it]].
* ''Film/TheFifthElement''. In the famous scene where Zorg demos the ZF-1 for the Mangalores, he proudly shows off the "replay button" feature, firing a single bullet at the target, then pointing the gun in the opposite direction and firing on full auto; all the bullets curve backwards and hit the target where the first bullet did.
* Present in ''Film/GIJoeTheRiseofCobra'' and ''Film/GIJoeRetaliation'' in both arrow and bullet form respectively.

[[folder:Live-Action TV]]
* ''Series/{{Andromeda}}'': The Force Lance from the series did a lot of things including launching homing projectiles.
* ''Series/MightyMorphinPowerRangers'': Kimberly's arrows possess this ability, as memorably demonstrated in "Power Ranger Punks".
* ''Series/AlmostHuman'': The episode "You are Here" featured a 50 caliber homing bullet fired out of a very nifty rifle, guided through a city by advertising software.
* An episode of ''Series/{{Flashpoint}}'' revolved around a thief aiming to steal a prototype smartgun, which (unrealistically) used radio waves to mark and track a target. This results in Ed Lane getting shot despite being behind cover. In the end, the SRU team uses a radio jammer to prevent the gun's bullets from tracking their targets, enabling them to take down the perp.
* Fancy Lee of ''Series/{{Killjoys}}'' made then used a non-lethal non-line-of-sight dart that was not only portable and concealable but smaller than most normal darts.
* ''Series/BlakesSeven''. Dayna's favourite weapon was a small wheeled robot [[HyperspaceArsenal that she could produce from nowhere]] and send around a corner or into a room to blow up some hapless {{mooks}}.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'': Ranged weapons with the "seeking" enchantment.
* ''TabletopGame/{{GURPS}}'': Homing weapons can be purchased as equipment, some even with character stats, or with the right imbuement [[TheMagicTouch touched]].
* ''TabletopGame/MutantsAndMasterminds'': An advantage one can buy allows any power an additional opportunity to hit fitting in the "attack" aspect.
* ''TabletopGame/Warhammer40000'':
** In the GaidenGame ''TabletopGame/{{Necromunda}}'', and the background material of ''Warhammer 40,000'' itself, the combat shotguns used by the law enforcement officers of the Adeptus Arbites and Necromunda Enforcers are equipped with special Executioner rounds as standard. These rare, [[FantasyMetals adamantium-tipped]] projectiles contain sensors and a primitive robotic brain that allow it to lock onto energy patterns and seek them out with unerring accuracy.
** The closest thing the orks have to a smart projectile is the Grot Bomb, essentially a missile with a cockpit piloted by a gretchin so it can make crude corrections to its trajectory. The gretchin is not informed of what happens once it hits the target, but it does give some semblance of accuracy to the army that named MoreDakka.

* ''VideoGame/{{Jumpman}}'' has projectiles that move slowly from the side of the screen. Once they are aligned (i.e. same horizontal/vertical position), they accelerate and move towards Jumpman. They only make one turn, and thus are easily dodged by moving.
* The Red Shells and Spiny (aka. "Death-on-Swift-Wings-Comes-for-You") Shells in ''VideoGame/MarioKart''.
* ''VideoGame/{{Worms}}'', of course, offers homing missiles as well as exploding homing pigeons and a magic bullet that spell's instant death to who-ever is locked onto. ''Worms 2'' had some special weapons that included a homing airstrike and a ''homing cluster grenade''.
* Franchise/SonicTheHedgehog himself can become this through the Homing Attack. Other characters can do it as well, such as Shadow, Amy, and Espio.
* The upgraded single missile in ''VideoGame/DiddyKongRacing''.
* In ''VideoGame/ChimeraBeast'' your eater could evolve to have ExtraEyes on its body, which could then be fired out when you did your ChargedAttack. They homed in on enemies.
* ''VideoGame/{{Einhander}}'' had an ''awesome'' version of this- the Wasp missiles homed in on ''both background AND foreground targets'' as well!
* The homing laser beams and balls in ''VideoGame/{{Recca}}''.
* ''VideoGame/{{Tyrian}}'' has Heavy Guided Bombs and Guided Micro Bombs, the latter of which is dangerously close to a GameBreaker as it was akin to MacrossMissileMassacre.
* The chaser weapon in ''VideoGame/GunstarHeroes'' and ''VideoGame/AlienSoldier''.
* The homing missiles in ''VideoGame/BangaiO Spirits''.
* The H weapon in ''VideoGame/{{Contra}} III'' and subsequent ''Contra'' games.
* 'Homing' is one of your three weapons in ''Over Horizon'', but with Weapon Edit you can give your other weapons minor homing tendencies as well.
* The high-level missiles in ''VideoGame/{{Darius}} Gaiden'' and ''VideoGame/RType III'' home in on targets.
* ''VideoGame/InTheHunt'' had the missiles weapon, which would home in on targets above the water surface.
* The central mechanic of ''VideoGame/{{Rayforce}}'' is its lock-on laser beams. Similar beams appear in ''VideoGame/{{Ikaruga}}'' and ''VideoGame/{{Genetos}}''.
* Two of the weapons in ''VideoGame/RadiantSilvergun'' shoot homing projectiles.
* Anti-Aircraft missiles are one of the more useful subweapons in ''Tetrastar''.
* Pretty much all of the ''VideoGame/{{Touhou}}'' games have this as an available shot-type, usually held by Reimu. They also occasionally have homing projectiles as enemies' attacks -- most often in the form of bullets that periodically reorient themselves, but there are also projectiles with true homing, like Seiga's ball lightning.
* ''VideoGame/BubbleTanks 2 and 3'' have seeker missile [[SecondaryFire sub-weapons]], which do a good amount of damage.
** There's also the [[TheVirus Doomsday Infector]], which infects an enemy with a homing virus. The virus then starts sapping the enemy of health, and when the enemy dies, it releases 1-3 more of the virus to infect more enemies.
* One of the weapons in the arsenal of ''VideoGame/{{Descent}}'' is homing missiles.
* ''VideoGame/{{Unreal}}'' and ''VideoGame/UnrealTournament'' have a homing missile as an alternate fire for their rocket launcher.
* Creator/{{Rare}}'s ''VideoGame/BanjoTooie'' featured a Homing Egg code.
* The ''Franchise/{{Castlevania}}'' series has had multiple projectiles of this type, including the Thunder Orbs used by Sypha in ''VideoGame/CastlevaniaIIIDraculasCurse'' and Yoko in ''VideoGame/CastlevaniaDawnOfSorrow'', the Spirits summoned by Alucard in ''VideoGame/CastlevaniaSymphonyOfTheNight'' and Charlotte in ''VideoGame/CastlevaniaPortraitOfRuin'', Carrie's magical fireballs in ''VideoGame/{{Castlevania 64}}'', and the Homing Daggers used by Nathan in Shooter Mode of ''VideoGame/CastlevaniaCircleOfTheMoon''.
* The Sharpshooters in ''VideoGame/DragonNest'' combine this with BeamSpam.
* Missile type weapons in ''VideoGame/{{Prototype}}'' will just home in on targets, which can be good or bad depending on who's shooting them.
** Observe carefully the AI helicopters firing a Hellfire missile at you as you leap wildly everywhere. Their missile [[TheComputerIsACheatingBastard both leads and homes in on you]].
* The Homing Missiles in ''VideoGame/HeavyWeapon'', which only [[AntiAir home in on air targets]]. There were also two kinds of annoying helicopters that fire homing missiles at you, jets with DeflectorShields that do the same, and 13 of the 19 bosses have some kind of homing missile attack.
* [[AIIsACrapshoot Sektor]] of ''Franchise/MortalKombat'' fame shoots homing missiles as a special move in ''VideoGame/MortalKombat3'' and ''VideoGame/MortalKombat9'', although in the latter it uses up a third of the Super Meter.
* Amazons in ''VideoGame/DiabloII'' can fire homing arrows. An early bug combined this with the Piercing skill to make the arrows home onto an enemy, hit them, pass through them, then turn around and do it again.
** Demon Hunters in ''VideoGame/DiabloIII'' can do the same. Overlaps with PinballProjectile when done in narrow passages, as it will look like the arrow bounces off the walls. In open spaces, however, the Demon Hunter can fire an arrow in the complete opposite direction of an enemy and the arrow will simply make a sharp turn mid-air and hit the enemy anyhow. Furthermore, the Demon Hunter has various skills that can also be upgraded with runes to fire homing rockets.
* Throughout ''Franchise/{{Halo}}'':
** ''VideoGame/HaloCombatEvolved'' introduced franchise staples the [[AbnormalAmmo Needler]] and Plasma Pistol.
** ''VideoGame/{{Halo 2}}''[='s=] Rocket Launcher can home in on vehicles, turrets, and Sentinel Enforcers.
** ''VideoGame/{{Halo 3}}'' and ''VideoGame/Halo3ODST'' have the Missile Pod, which is capable of {{Roboteching}}.
** In ''VideoGame/HaloReach'', the Rocket Launcher and Rocket Hog turret can home in on aircraft (which has carried over into subsequent games), the Banshee Bomb can lock on to vehicles and turrets, and the Plasma Launcher can lock onto both vehicles and infantry.
** In ''VideoGame/Halo4'', the campaign version of the Mantis can fire homing missiles.
** In ''VideoGame/Halo5Guardians'', the Suppressor and Boltshot now fire tracking shots, with the Scattershot also able to do so if you first ricochet its shots off something. The campaign version of the Mantis can now lock onto multiple enemies with its missiles at once, though the standard multiplayer version can only do so against aircraft. Additionally, several REQ variant weapons/vehicles in Warzone have special lock-on capabilities.
* ''Videogame/GunsOfIcarus'' includes homing rocket turrets.
* ''VideoGame/AceCombat'' has a variety of missiles for the player, ranging from the standard generic Missiles that can target anything and come in large numbers to more specialized long-range missiles that may do extra damage or lock on to multiple targets. Enemy pilots, especially ace pilots, can evade shots that aren't lined up properly.
** Enemy aircraft, ships, and SAM units can launch missiles at the player. Their homing capabilities are about equal to the player's standard missiles.
* The Bullet Bills in various 3D ''Franchise/{{Mario}}'' games home in on Mario to varying degrees.
** As well as the Missile Bills in the 2D games.
** In ''VideoGame/NewSuperMarioBrosWii'', Ludwig Van Koopa can shoot homing fireballs (thankfully much slower than regular fireballs).
* ''VideoGame/DonkeyKongCountry''
** ''VideoGame/DonkeyKongCountry3DixiesKongQuest'': Barbos's shellfish flunkies home in on Enguarde, and and must be [[MisguidedMissile manipulated]] to knock out his barriers.
** ''VideoGame/DonkeyKong64'': A big beeping missile with a face (of course) is used by the upgraded Army Dillo. The Kongs can also find limited amounts of Homing Ammo for their guns.
* One of Gruntilda's spells in ''VideoGame/BanjoKazooie'' can't be avoided without using [[InvincibilityPowerUp invincibility]].
* The boss of stage 5 of ''VideoGame/MrGimmick'' shoots slow homing missiles that block your attacks.
* A fairly annoying attack by bosses in ''VideoGame/{{Darius}}'' games.
* Many enemies, minibosses and bosses in ''VideoGame/MegaMan'' franchise fire homing projectiles.
* ''VideoGame/SeriousSam I'' has reptiloids and final boss of ''The First Encounter'' shooting these. In ''VideoGame/SeriousSam II'' the enemies shooting homing missiles include witches, helicopters and two types of sci-fi orcs.
* In the similar ''VideoGame/WillRock'', two bosses (Hephaestus and Medusa) uses this.
* The revenants in ''VideoGame/{{Doom}}'' launch missiles that the player has to get real creative to avoid.
* Hellfire missiles fired by AI AH-64 helicopters will both lead and home onto Alex in ''VideoGame/{{Prototype}}''. But Alex cannot do the same when he's in an AH-64, meaning TheComputerIsACheatingBastard.
* Nearly all secondary weapons in ''VideoGame/FreeSpace'' - and some ''do'' LeadTheTarget.
* Several of Shepard's powers in ''VideoGame/MassEffect2'' and ''VideoGame/MassEffect3'' fire projectiles that home in on the target, allowing the powers to be fired in an arc around obstacles. Almost all of these powers when used by Shepard's squadmates instantly hit the target instead.
* ''Videogame/TeamFortress2'': Custom game mode "Dodgeball" has rockets which, unlike normal ones fired by the Soldier, home in on a player. The game is to use the Pyro's [[AttackReflector compression blast]] to deflect the rocket at the enemy team, who are trying to do the same.
* If you get your Dark-Elf's Disease Bolt spell high enough in ''Videogame/ChampionsOfNorrath'', it will home in and hit the nearest enemy.
* ''Videogame/DarkSouls'': Projectile sorceries usually home on the locked enemy.
** And in this game, even arrows veer mid-flight to better hit you.
* [[{{BFG}} Gun-type God Arcs]] in ''VideoGame/GodsEaterBurst'' can be loaded with homing bullets and ''lasers''. Saves some frustration when you're trying to hit something fast-moving, but homing attacks target center of mass and so [[AttackItsWeakPoint can't be used to aim at specific points on the Aragami]].
* Achieved accidentally as an artifact of the rendering engine in ''VideoGame/CityOfHeroes''. Most single-target attacks have a visible effect that take a short time to reach their target, so if an attack that has been determined to be a hit goes off against a moving target, the visible effect (fire beam, energy blast, etc.) will arc to follow the target, no matter how fast it moves or how many turns it makes. It is sometimes possible, with a travel power at the speed cap or with Teleportation, depending on where you start, to reach a street exit to another zone and exit the zone before the visible blast hits you, although you will still take the damage from the attack.
* A quasi-example: ''VideoGame/RaptorCallOfTheShadows'' has orange flak balls that are shot at your plane instead of the normal ones that are shot straight. A large majority of Mooks, airborne and grounded, use these on you, especially on the later levels and harder difficulties; these make them GoddamnedBats.
* The best weapon pickup of ''VideoGame/PrehistorikMan'' was an egg that allowed the player to fire homing (and very damaging) dinosaurs at enemies.
* ''VideoGame/SteelDiver: Sub Wars'' has homing torpedoes. Each sub can only fire three before needing to pick up homing torpedo pickups to replenish them, and homing torpedoes fire much slower than their non-homing counterparts.
* Missile-type weaponry in both ''[[Videogame/BattleZone1998 BattleZone]]'' FPS/RTS games generally have some homing mechanic. Fire-And-Forget missiles and [[MacrossMissileMassacre Swarm missiles]] can be dumbfired and will home in on the nearest target, whereas the Shadower and Comet require a target lock. Depending on the missile type, they require either a visual or radar contact, allowing infrared or [[InvisibilityCloak visual cloaking]] to fool certain types of missiles. Seeker mines will float towards the nearest enemy and detonate on contact.
* ''Videogame/{{Warframe}}'''s Buzlok rifle can fire a homing dart onto an enemy, which then causes all subsequent shots to arc towards the dart - even if the gun is fired in the opposite direction.
* Homing missiles are an option in most of the ''VideoGame/TwistedMetal'' series, and even fire missiles have a limited ability to veer towards targets close to their trajectory. Spectre's ghost missiles will home in on you even if doing so makes them pass harmlessly through walls and road.
* ''VideoGame/FromTheDepths'': Most of the weapons fired from the missile system are capable of homing in on their target.
* ''[[VideoGame/EarthwormJim Earthworm Jim 2]]'' had a weapon that fired homing projectiles [[VisualPun that looked like homes]].
* In ''VideoGame/{{Evolve}}'', the support hunter Bucket has a laser guided missile launcher as his primary weapon. Because the projectiles home on the laser rather than the monster, clever players can use this to lead the target or even shoot around obstacles. Another hunter, Emet, has a variant where you first fire a pellet that the rest of his missiles will home in on.
* All ships in ''VideoGame/StarWarsBattlefront2015'', from the standard Rebel X-Wing to Darth Vader's TIE Advanced, come equipped with homing photon torpedos that can be fired after locking onto an enemy ship for a few seconds.
* In ''VideoGame/TheElderScrollsVSkyrim'''s ''Dragonborn'' DLC, Seekers are a {{Cthulhumanoid}} form of [[OurDemonsAreDifferent lesser Daedra]] in service to Hermaeus Mora, the [[OurGodsAreDifferent Daedric Prince]] of [[KeeperOfForbiddenKnowledge Knowledge]]. Seekers, befitting their name, can use ranged VampiricDraining spells which home in their targets.
* All missile weapons in ''VideoGame/{{Stellaris}}'' have 100% tracking, meaning they'll virtually never miss their target, and they're even capable of going after another one if the original victim is destroyed before they reach it. The only way to get rid of such a SuperPersistentMissile is by shooting it down with fighters or point defences, and even that's not foolproof since high-level missiles and torpedos can be more resilient and nimble than fighter craft, allowing them to tank or evade defensive fire until they strike home.
* ''VideoGame/TreasurePlanetBattleAtProcyon'' has Torpedoes and Mines. Torpedoes follow their target until they either hit something, run out of time and detonate, or are shot down by Point Defence Lancers. Mines act the same way except they don't start moving until an enemy moves close enough to activate them.

[[folder:Web Animation]]
* ''WebAnimation/DSBTInsaniT'': Robo-Wolf and [[Franchise/{{Digimon}} Guardromon]] can shoot missiles. They aren't super-persistent though.

[[folder:Western Animation]]
* ''WesternAnimation/{{Ben 10}}'': The series and the movie ''Destroy All Aliens'' has both homing and non-homing projectiles.

[[folder:Real Life]]
* [[http://www.popsci.com/technology/article/2012-05/rough-sketch-self-guided-bullet A group of engineers at Sandia National Laboratories are working on developing a homing .50 sniper's bullet.]] They started by removing the rifling from the barrel and adding movable stabilizer fins to the round. Electronics inside the bullet allow it to home on its target, to a point (it obviously won't be able to turn back around if you miss).
* In the meantime, the Italian and French navies already field it in their artillery: as their CISW doctrine calls for larger and longer-ranged guns in place of faster-firing but shorter-ranged weapons, the Italian firm OTO Melara (through its Otobreda branch) developed guided shells for their 76mm [[MoreDakka Super]] [[ExactlyWhatItSaysOnTheTin Rapid]] multi-purpose guns used by both navies, and, as the Italian Navy wanted more, [[UpToEleven developed a 127mm-caliber version and the new 127/64 Lightweight gun to fire it]].
** And to continue the long Italian tradition of CombatPragmatism in an era where some of the earlier tricks are done by everyone or would be war crimes, Iveco (maker of the Centauro tank destroyer) and OTO Melara gave us the [[http://www.military-today.com/artillery/porcupine.htm Porcupine]]: a prototype consisting of a Centauro chassis mated with a 155mm howitzer capable of firing homing shells to targets up to 60 km away. And the ability to hit the poor target with four of them ''at the same time''. Let's face it, when the Italians go at war they're assholes.
*** Multiple Rounds, Simultaneous Impact is common in modern artillery systems.
