# Digital Combat Simulator

Digital Combat Simulator (DCS) is a combat flight simulation game developed primarily by Eagle Dynamics and The Fighter Collection.
Several labels are used when referring to the DCS line of simulation products: DCS World, Modules, and Campaigns. DCS World is a free-to-play game that includes two free aircraft and two free maps. Modules are downloadable content that expand the game with add-on aircraft, maps, and other content. Campaigns are scripted sets of missions. Modules and campaigns are produced by Eagle Dynamics as well as third-parties.

## Gameplay

DCS World is a study sim in which players learn how to operate aircraft using realistic procedures. Aircraft are meticulously modeled from real-world data, including authentic flight models and subsystems and detailed cockpits with interactive buttons and switches. Digital manuals document the history, systems, and operation of each aircraft in extensive detail. The game has extensive support for joysticks and HOTAS input devices ranging from gamepads to 1:1 replica cockpits.
DCS World supports a wide variety of combat operations including combat air patrol, dogfighting, airstrikes, close air support, SEAD, and airlifts. Dozens of military airplanes and helicopters are available, spanning eras from World War II through the Cold War into the early 21st century. Popular modules include the AH-64D, F-16C, F/A-18C, F-14, and A-10C.
A mission editor is included for users to create their own scenarios and campaigns with support for scripting in Lua. Users can host their own servers with user-made missions for PVE and PVP multiplayer. The community has developed tools to create missions using procedural generation and real-time editing, and hosts servers that simulate dynamic battlefields.
DCS World acts as a unified modular platform, in contrast to previous installments in the series which were standalone products. This allows users of different modules to switch between aircraft and play together within a single game client. The platform also allows third-party developers to publish modules through Eagle Dynamics' storefront. Community mods have also been produced, such as the A-4E, C-130J, T-45C, UH-60L, and the JAS-39 Gripen.

### Use as a military Air Force training aid

Some air forces have used DCS World as a training aid. A professional version called Mission Combat Simulator (MCS) is available for organizational use.
The United States Air Force's 355th Training Squadron at Davis-Monthan AFB makes use of DCS as an instrument and weapons-system trainer for the A-10C. The use of virtual reality headsets is preferred for a more immersive experience.
Before the Mirage 2000C was retired in 2022, the French Air Force used DCS for both instrument and tactical training with the M-2000C module, citing insufficient numbers of professional simulators.
Ukrainian pilots have trained using the A-10C II and F-16C modules for DCS World.

## Setting

DCS World has a number of maps available from Eagle Dynamics and third parties:

### In development

* Mariana Islands WWII - A free WWII version of the Mariana Islands region as it was in the summer of 1944.

## Development

DCS World traces its lineage directly from the Flanker and Lock On: Modern Air Combat series of combat flight simulator games. Three standalone titles were released under the DCS name from 2008 through 2011. The first was DCS: Black Shark as a simulation of the Kamov Ka-50. DCS: A-10C Warthog, a standalone simulation of the A-10C, was released in February 2011. An upgrade for Black Shark, DCS: Black Shark 2, was released in November 2011 and allowed for network multiplayer with Warthog.
The open beta of DCS World was launched in May 2012. Warthog and Black Shark 2 were made available as modules. Flaming Cliffs 3 was released later that year, which added aircraft from Lock On as modules of DCS World. The first third-party module, the Bell UH-1H Huey, was also announced in 2012.
DCS World 1.5 was released in October 2015 featuring a new DirectX 11 graphics engine and a unified executable.
In November 2015, DCS World 2.0 was released as an open alpha while 1.5 continued to be supported as a stable release. 2.0 added support for more detailed terrain including the Nevada Test and Training Range map. DCS World 2.1 was released in 2017 and added support for deferred shading and physically based rendering, followed by DCS World 2.2 that same year. The next major release, DCS World 2.5, added an improved Caucasus map in 2018. 2.5 replaced 1.5 as the stable release version coinciding with a Steam release.
DCS World 2.7 was released as an open beta in April 2021, with new weather and clouds as well as improved piston engine simulation. 2.7 became the stable release in June of that year. DCS World 2.8 was released as an open beta in October 2022, improving atmospheric effects and AI basic fighter maneuvers. DCS World 2.9 was released as an open beta in October 2023, featuring support for Nvidia DLSS and AMD FSR, improvements to multiplayer voice chat, higher fidelity data link and radar simulation, and new graphics and camera effects. The open beta version of DCS World was discontinued at the end of 2023, and all subsequent updates have been released directly to the stable release version.
In July 2024, Flaming Cliffs 2024 added survey sim versions of the F-5E Tiger, F-86F Sabre, and MiG-15bis. These versions feature professional flight model and updated 3D modelling comparable to the modelling and texturing update of Flaming Cliffs 3 that occurred in March of 2024. The 2024 modules were adapted from work created for another Eagle Dynamics product, Modern Air Combat, which was "shelved" earlier in 2024. Flaming Cliffs 2024 is available as a full pack, as an upgrade for owners of Flaming Cliffs 3, or as individually sold modules.
Over the course of development, modules have introduced new features to the simulator including improved flight models and damage models, multi-crew aircraft with multiple players or AI acting as crew and enhanced FLIR simulation.

### Third-party developers

A large portion of aircraft and terrains in the DCS World ecosystem are developed by companies officially licensed by Eagle Dynamics to produce modules for the simulator. Third parties also create single-player campaigns. Third party content is sold through Eagle Dynamics' storefronts on their eShop and Steam.
In 2018, third party developer VEAO ceased development of their Hawk module. Eagle Dynamics offered full refunds to customers and introduced a code escrow policy for future third party agreements.
In June 2018, Belsimtek, a Belarusian developer, announced its merger with Eagle Dynamics. The company's website was taken down in 2020.

## Reception

PC Gamer reviewed the DCS: A-10C Warthog module with a rating of 92/100. IGN praised the care and attention to detail, though remarking a level of inaccessibility: "Yes, there is a 44-page 'Quickstart' guide and yes, there are tutorials – a bevy of lengthy, highly instructive tutorials, actually – but precious little of this is designed for the neophyte or even the marginally experienced jet jock."
SimHQ praised the Ka-50 module, noting the attention to technical details such as the recoil of the main gun affecting flight dynamics, along with smaller details such as the windscreen wiper having several modes. Also noted was the difficulty of flying the helicopter. The Ka-50 simulation earned SimHQ's Simulation Product of the Year award for 2008.
PC Pilot reviewed the third-party F-14 Tomcat module with a score of 97/100. The review concluded that "[DCS: F-14 Tomcat] is truly one of the greatest simulation modules ever created for a PC flight simulator." The complexity and depth of the multi-crew cockpit and systems was described as exceptional.
HeliSimmer.com's article on the work-in-progress AH-64D module's early access version praised the 3D modeling and soundscape while noting the incomplete systems and critiquing the flight model's accuracy compared to a real helicopter. Despite these shortcomings, it was said to be "the best representation of an AH-64D since Jane's Longbow 2."
DCS World's gameplay has been critiqued, in contrast to its aircraft simulation. FlyAndWire wrote that "DCS is the best 'cockpit simulator' around" but criticized the interaction between the aircraft and the game environment.
