== Unit Designations/Hull symbols == ''Most are taken from the standard [https://en.wikipedia.org/wiki/1962_United_States_Tri-Service_aircraft_designation_system US Tri-service aircraft designation system] and [http://www.navweaps.com/index_tech/index_ships_list.php USN hull classifications]'' ''Ordered by approximate size.'' === Aether === [Nothing in here yet] === Air === ===== Basic aircraft ===== * Attacker - Precision anti-surface * AWACS - Flying command post, typically fitted with a [[Strategic Antenna|strategic antenna]] as well as multiple normal detection systems to support friendly units. * Bomber - Anti-surface. Typically big and lumbering, but able to carry a very heavy payload. * Fighter - Anti-air. Typically small and agile, able to dodge enemy weapons. ==== Deciphering the tri-service system ==== Some player-made aircraft, and a few of those in service with the Steel Striders Air Force, are designated according to the US Tri-service aircraft designation system. The system is laid out in the format: (Status prefix)(Modified mission)(Basic mission)(Aircraft type)-(Design number)(Series letter) (Name). * Status prefix - Shows what's currently going on with the aircraft, for example if it's grounded due to a game update messing with one of its systems, or if the aircraft is still a prototype {| class="wikitable mw-collapsible mw-collapsed" !Symbol !Meaning !Description |- |G |Grounded |Aircraft which have been rendered unflyable or otherwize nonfunctional by a game update, but which you expect to bring into service again. |- |J |Temporary | |- |N |Testbed |For example, you may refit a particular aircraft (a large transport, for example) as a "missile testbed" with every guidance system (Laser designator + multiple Lua boxes + [[General Purpose Processing Card|GPP cards]] to spare), 12(+?) different sizes and length of missiles, and multiple variations of each to compare homing/guidance systems, APN Gain, etc. It's a unit that's probably not going into combat unless you're desperate, so putting an "N" in front of its name will keep it from being mixed up with other airplanes. |- |X |Testbed |in-service aircraft modified to test new technologies like stealth, thrust vectoring, Lua-based AI, etc. |- |Y |Prototype |WIP projects. Stuff you're currently working on and expect to actually use in combat once finished. |- |Z |Napkin Drawing |Stuff you haven't actually started building yet. Most people won't have any "Z-planes" in their blueprint folders because once you've created a blueprint you've already entered the Prototype "Y-plane" stage of development. |} * Modified Mission - Shows that the aircraft was modified to perform a different misison than originally designed. {| class="wikitable mw-collapsible mw-collapsed" !Symbol !Meaning !Description |- |A |Attack |Modified to function as an attacker. |- |C |Cargo |Modified to carry materials. |- |D |Drone control |Refitted with [[Control Terminal|Control terminals]] and [[Video Screen|Video screens]] for remotely controlling other units. |- |E |EWAR |Modified to perform some sort of EWAR function. See the EWAR basic mission for more information. |- |F |Fighter |Modified to act as a fighter. |- |K |Tanker |Modified to resupply friendly units with [[Resource|Fuel]]. |- |M |Multi-mission | |- |O |Observation |Modified to act as a spotter aircraft. |- |P |Patrol |Modified to also function as a patrol aircraft. |- |Q |Drone-ified |Refitted with a [[Remote Vehicle Controller|Remote vehicle controller]] and [[Wireless Camera|Wireless camera]]. |- |R |Reconaissance |Modified to perform reconaissance missions. |} * Basic mission - What the aircraft was originally built to do. {| class="wikitable mw-collapsible mw-collapsed" !Symbol !Meaning !Description |- |A |Attacker |Originally designed as an attacker (for ''tactical'' missions against enemy ships and ground vehicles) |- |B |Bomber |Originally designed as a bomber (for ''strategic'' missions against Fortresses and structures. |- |C |Cargo |Originally designed to transport materials |- |E |EWAR |Designed to perform some kind of [[detection]]-related function such as: ECM: Electronic Counter Measures - Messing with the enemy's detection/fire control systems: * Blinding the enemy with [[Advanced Cannon|Smoke shells]]. *Dispensing [[Defences|chaff]]. * Using a [[Sensor Scrambler ECM|Sensor Scrambler]] to reduce the range accuracy of the enemy's detection systems. ECCM: ECM Counter Measures - Messing with the enemy's ability to mess with your detection/fire control systems: * Using a Radar Warning Reciever to detect and destroy the nearest enemy ECM Sensor Scrambler usually helps. * Carring large numbers of sensors to "burn through" the enemy's sensor scrambling through sheer number of detections per second is a viable strategy. ESM: Electronic Support Measures - Helping friendly units find the enemy: * Launching Sticky Flare-equipped missiles at the target to help your IR missiles find it. * Pointing a Laser Designator at the enemy to guide friendly missiles. |- |F |Fighter |Originally designed as a Fighter |- |K |Tanker |Originally designed as a Tanker |- |O |Observation |Broadcasts target data using a [[Inter Vehicle Transmitter|Inter-vehicle transmitter]], perhaps also using a [[Missile Laser Emitter|Laser designator]] to guide friendly missiles onto the target. Think of this guy as a small, expendable |- |P |Patrol |Originally designed to lug around a big Strategic antenna. |- |R |Reconnaissance |Flies through map squares to detect enemy vehicles (redundant unless auto-detection has been disabled). Likely carries several different sensor types and possibly sonobouys. Although currently irrelevant, recon aircraft |- |S |ASW |Originally designed for anti-submarine operations. |- |X |Research | |} * Aircraft Type - For anything out of the ordinary. {| class="wikitable mw-collapsible mw-collapsed" !Symbol !Meaning !Description |- |H |Helicopter |It's a helicopter. |- |Q |Remotely controlled. |Technically refers to UAVs, but since virtually every unit in FtD has an AI mainframe, we'll use Q to indicate that an aircraft is designed to be remotely controlled. That is to say, it lacks a [[Seat]] and [[Vehicle Controller|Vehicle controller]], but is fitted with at least one [[Wireless Camera|Wireless camera]] and a [[Remote Vehicle Controller|Remote vehicle controller]] |- |S |Spaceplane |Capable of ascending to and maneuvering in space. |- |V |VTOL/STOL |Designed with Vertical- or Short takeoff and landing capabilities. |} * For each basic mission or vehicle types, design numbers are assigned consecutively. * Series letters denote various modifications that don't modify the mission type. Example tri-service system aircraft designations: {| class="wikitable mw-collapsible mw-collapsed" !Status prefix !Mission (modified) !Mission (Basic) !Aircraft type !- !Design number !Series letter !Name != !Designation !Description |- |Y | |A | | - |4 | | | |YA-4 |Prototype attacker |- | | |A | | - |4 | |Anteater | |A-4 "Anteater" |Attacker |- | |Q |A | | - |4 | | | |QA-4 |Remotely controlled version |- |Z | |B | | - |12 | | | |ZB-12 |Napkin drawing |- |Y | |B | | - |12 | | | |YB-12 |Prototype bomber |- | | |B | | - |12 | |Branta | |B-12 "Branta" |Bomber |- | |E |B | | - |12 | |Eagle Owl | |EB-12 "Eagle Owl" |Refitted for EWAR |- | |P |B | | - |12 | |Albatross | |PB-12 "Albatross" |Refitted for patrol operations |- |X | |B | | - |12 | | | |XB-12 |Refitted as a testbed |- |Y | |C | | - |6 | | | |YC-6 |Prototype transport |- | | |C | | - |6 | |Condor | |C-6 "Condor" |Transport |- | |A |C | | - |6 | |Argentavis | |AC-6 "Argentavis" |Refitted as a [https://en.wikipedia.org/wiki/Gunship gunship] |- | |E |C | | - |6 | |Eagle eye | |EC-6 "Eagle eye" |Refitted for EWAR |- | |K |C | | - |6 | |Kea | |KC-6 "Kea" |Refitted as a tanker |- |Z | |F | | - |3 | | | |ZF-3 |Napkin drawing |- |Y | |F | | - |3 | | | |YF-3 |Prototype fighter |- | | |F | | - |3 | |Falcon | |F-3 |Fighter |- | |A |F | | - |3 | | | |AF-3 |Refitted as a Strike fighter |- | |E |F | | - |3 | | | |EF-3 |Refitted for EWAR |- | |R |F | | - |3 | | | |RF-3 |Refitted for Reconnaissance |- | | |X | | - |1 | | | |X-1 |Research aircraft |- |Y | |A |H | - |17 | | | |YAH-17 |Prototype attack helicopter |- | | |A |H | - |17 | | | |AH-17 |Attack helicopter |- | | |S |H | - |17 | | | |SH-17 |ASW version |} === Land === * {| class="wikitable mw-collapsible mw-collapsed" !Designation !de-acronymized !Description |- |MBT |Main Battle Tank | |- |MLRS |Multiple Launch Rocket System |A katyusha-style rocket-launcher vehicle |- |SPAAG |Self-propelled anti-aircraft gun |Mobile anti-aircraft artillery |- |SPG |Self Propelled Gun |A gun on wheels (or tracks) |- |TD |Tank Destroyer |Specialty anti-tank vehicle, typically with very heavy frontal armour. |- |TEL |Transporter Erector Launcher | |- |TELAR |Transporter Erector Launcher And Radar | |- |TLAR |Transporter Launcher And Radar | |} * === Sea === {| class="wikitable mw-collapsible mw-collapsed" |+ Aircraft Carriers !Hull Symbol !Designation !Description |- |CV |Fleet Carrier |A cruiser-style hull fitted with a large flat flight deck for launching fighters and light bombers. |- |CVE |Escort Carrier |A carrier built from some kind of cargo vessel. Not a bad idea since a cargo ship will likely have enough space to fit the ammo and fuel storage needed to resupply a small airgroup. It might not be as fast as a proper fleet carrier though, and you may find that the weight of the flight deck hurts its seakeeping qualities. |- |CVS |ASW Carrier |A carrier fitted for ASW duties. This usually means a lot of torpedo bombers, cram bombers, magnetic mine bombers, and heavy anti-torpedo and anti-missile defences. Traditionally, ASW carriers also employed a fairly large number of helicopters. |} {| class="wikitable mw-collapsible mw-collapsed" |+ Surface Combatants !Hull Symbol !Designation !Description |- |BB |Battleship |Carrying the heaviest guns in the fleet, and built to take a punch and keep going at a steady -though not exactly rapid- pace, a battleship is a floating fortress of a ship, although the later Fast Battleships increased the speed somewhat (at some cost to their maneuverability). |- |CB/CC |Battlecruiser |Evolved from the Armoured Cruiser, battlecruisers are traditionally of either the English or the German variety. Both feature higher speeds than a battleship, but the former sacrifices armour in favour of carrying battleship-grade weapons while the latter offers near-battleship armour at the cost of slightly lighter armament. Eventually a third type evolved, which favoured increasing the waterline length and displacement instead of sacrificing protection or firepower. This third type causes some confusion as to the origin of the term "Fast Battleship". |- |CA (Early) |Armoured Cruiser |Featuring both a waterline armour belt and the Protected Cruiser's angled internal belt and protective coal bunkers, an Armoured Cruiser was typically similar in length to the battleships of the day, but with a narrower beam, higher speed, and lighter weapons, their main armament typically being similar to the secondary armament of a battleship. This classification was also bestowed upon the Deutschland-class of ''Panzerschiffe'' built by the German navy in 1929-1936 for use as commerce raiders, although their heavy armament granted them the unoficcial designation of "Pocket Battleships" by the british. |- |CA (Late) |Heavy Cruiser |An evolution of the Light Armoured Cruiser, the Heavy Cruiser was defined by the London Naval Treaty as having a main gun caliber no larger than 203mm. In FTD terms this might mean a gun armament slightly favouring hitting power over rate of fire and shell speed. |- |CL |Light Armoured Cruiser |An evolution of the Protected Cruiser, the advent of oil-fired boilers made storing fuel along the ship's side for protection a questionable idea, and so Light Armoured Cruisers had a simpler armour scheme consisting of a vertical waterline belt attached to the sides of the hull, and a flat armoured deck. Eventually the London Naval Treaty redefined the "Light Cruiser" as having a main gun caliber of no more than 155mm. In FTD terms, this might mean a gun armament with a bias towards fighting agile, perhaps aerial, targets with a high rate of fire and/or shell speed at the cost of hitting power. |- |C |Cruiser (Protected) |These gun-armed ocean-going vessels are fairly fast, but lightly protected. Their armour protection typically consisted of a single armoured deck, the sides of which were extended downward below the waterline to form a sort of angular upside-down bowl-shape that protected (ahem) the ship's boilers, engines, and ammunition stores. In addition to the sloped internal belt, the ship's waterline was also protected (ahem) by storing the fuel supply (coal) in the triangular space between the sloped armoured belt, the ship's side, and the deck above. Their main gun armament is heavy enough that they typically use two or even three different sizes of guns, the main battery being made for heavy anti-ship use, and the secondary and tertiary batteries being successively lighter and increasingly optimized for use against Torpedo Boats, Motor Torpedo Boats, and other small, fast targets. |- |DD |Destroyer |Ocean-going torpedo-boat with a secondary gun armament for destroying other torpedo boats as well as other targets of opportinity. Later advancements included dual-purpose guns, and eventually replacing some (or all) of their torpedo armament with anti-ship missiles. |- |FF (Post-WWII) |Frigate |Also referred to by the US Navy as a Destroyer Escort (DE) during the cold war, these were large dedicated high-endurance anti-submarine vessels with a secondary anti-aircraft role, and were used as convoy escorts. |- |FS |Corvette |Small ASW ship intended for convoy defence and patrolling coastal waters. Expected to be shielded from air and surface attack by friendly land- or carrier-based air cover or by larger friendly ships, they're liable to lose a fight against a gunboat |- |PG |Gunboat |A long-range patrol vessel intended to roam foreign coastal waters independently of the main fleet. Typically armed with two or more medium-sized guns for coastal bombardment and anti-surface work and a few light anti-aircraft weapons, larger models may even carry torpedoes. |- |PM |Missile Boat |Though small and fragile, these boats are cheap enough to be used in swarms, and they pack a mean punch! In addition to their missiles, they typically also carry some kind of autocannon, possibly a dual-purpose (DP) gun. Advanced models may also carry a CIWS, and the largest may even be fitted with a light SAM system. |- |PT |Torpedo Boat |Small high-speed coastal vessel intended for use in swarm attacks. They were/are mainly intended to prey upon large and unmaneuverable opponents such as battleships, carriers, and cruisers, and the occasional cargo ship. The may also useful as cheap reconnaissance craft, but are all but uncontrollable in rough seas. |} {| class="wikitable mw-collapsible mw-collapsed" |+ Submarines !Hull Symbol !Designation !Description |- |SS |Attack Submarine |An underwater counterpart to the destroyer, the attack submarine preys upon surface vessels and other submarines alike, mainly relying on torpedoes to punch holes in the enemy's hull. While perhaps less interesting than SSBs or SSGs, attack submarines may be better suited for fighting other submarines. |- |SSB |Submarine; Ballistic Missile |Mainly intended to attack surface vessels and ground targets, ballistic missile submarines in FtD typically either carry subvehicles with Tactical Nukes, or use vertically launched Large Missiles. The large missiles, in this case, may have a very slow turn rate or guidance delays to strike the enemy from above. |- |SSC |Submarine; Coastal |Similar to the Attack Submarine in purpose, coastal submarines operate in shallower waters where enemy craft have an easier time attacking them with CRAM and APS mortars, magnetic mines, and the like. As such, coastal submarines tend towards smaller size to decrease the risk of detection, as well as having greater maneuverability to navigate in confined waters. |- |SSG |Submarine; Guided Missile |Similar to the SSB in execution, SSGs typically forego the expensive complexities of trying to bring heavy firepower onto an enemy's deck from above. Instead, their missiles go straight to the target, hitting their sides without unnecessary complications. |- |SSM |Midget Submarine |A tiny submarine, perfect for sneaking up close to enemy vessels and capturing them. Alternatively, you could fit the SSM with an inter-vehicle transmitter and use it to provide targeting data for other ships. A third option is to mount a Missile Controller with a Laser emitter on a mast and use the boat to mark targets for long-range Laser-homing missiles launched by other vessels. |} {| class="wikitable mw-collapsible mw-collapsed" |+ Support Vessels !Hull Symbol !Designation !Description |- |AC |Collier |Because FtD's steam boilers burn plain old materials rather than coal, there's no need for colliers. Of course, that doesn't stop anyone from building some of their cargo ships to look like colliers and designate them accordingly. |- |AE |Ammunition Ship |Potentially a more dangerous assignment than being on the front lines, ammunition ships carry [[ammo]] from production facilities to the combat units. |- |AGD |Dredge Ship |A ship fitted with equipment for removing [[material]] from resource zones on the sea. |- |AK |Cargo ship |Moving material from resource zones to fuel and ammo processing plants may not be a glamourous taks, but it's one that needs to be done. Of course, your repair ships on the fronlines will need to be resupplied sooner or later, so a cargo ship's carreer might not be entirely uneventful. |- |AO |Oiler |While it's perfectly acceptable to build every combat vehicle with enough [[Fuel Engine|fuel]] storage to travel across Neter and back on one tank, there's some merit to the idea of offloading some (or most) of a fleet's fuel onto a purpose-built oiler. For starters, it saves some space and weight on your combat crafts. |- |AR |Repair Ship |We've got Simple fuel processors and we've got refineries. We've got ammo processors and we're about to get ammo factories. At some point the repair tentacles may or may not be pushed aside by a more material-efficient multi-block construction system. Until we know for sure, there's no benefit to sailing your damaged craft all the way back to your fortress to patch up their battle scars, so go ahead and slap some repair tentacles on a spare hull and give your fleet some mobile repair capability! |- |AT |Ocean Tug |A small ship with a Docking Station, used to move around Ammo, Fuel, and Material barges. |- |ATF |Fleet Ocean Tug |As above, but used to tow damaged combat craft over to the nearest repair ship. Because these tugs may operate as part of a fleet, you way want them fitted with some light defensive weapons in case a stray enemy fighter decides to have a go at them. |- |YM |Dredge Barge |Like a dredge ship, the dredge barge collects materials from the sea floor, but it has a very limited (if any) propulsion system, which makes it cheaper to build. |- |YO |Fuel Barge |They're like oilers, but with no propulsion system, which makes them much cheaper. On the off hand, you'll need a tugboat to move them around. |- |YR |Floating workshop. |Like a repair ship, except it's just a cheap barge with a few repair tentacles, some material storage, and enough engine power and fuel to keep the tentacles working. |} Extensions *-C: Extension meaning it's a coastal vessel, most notably used for coastal submarines (SSC). *-L: Extension meaning it's a lighter version of its original designation, most noticably used for CVL- Light aircraft carrier, which were smaller CVs carrying less planes and with a shorter naval range. *-V: Extension signifing the ship has aicraft carrying capacities while its class is not originaly intended to, generaly used for conversions (CAVs, BBVs, etc...). *-G: Extension signifing the ship uses missiles and/or guided missiles, came in during the cold war on most standard ship types, FFG, DDG, DEG, . *-N: Extension signifing the ship uses nuclear propulsion, came in during the cold war, used most notably for SSN- Nuclear powered submarines and CVN- nuclear powered aircraft carriers. Since nuclear ractors don't yet exist in FtD, we mostly use this extension for vehicles powered by RTGs. [[Category:Guides]]
