In addition to being the deepest human-made hole on Earth, Kola Superdeep Borehole SG-3 was, for almost three decades, the world's longest borehole in measured depth along its bore, until surpassed in 2008 by a hydrocarbon extraction borehole in Qatar.[3]
The second hole was started in January 1983 from a 9,300-metre (30,500 ft) depth of the first hole.[4] In 1983, the drill passed 12,000 metres (39,000 ft) in the second hole, and drilling was stopped for about a year for numerous scientific and celebratory visits to the site.[7] This idle period may have contributed to a breakdown after drilling resumed; on 27 September 1984, after drilling to 12,066 metres (39,587 ft), a 5-metre (16 ft) section of the drill string twisted off and was left in the hole. Drilling was restarted in September 1986, 7,000 metres (23,000 ft) from the first hole.[7][6]
Drilling of the fifth hole started in April 1994 from 8,278 metres (27,159 ft) of depth of the third hole. Drilling was stopped in August 1994 at 8,578 metres (28,143 ft) of depth due to lack of funds and the well itself was mothballed.[6][11]
The stated areas of study of the Kola Superdeep Borehole were the deep structure of the Baltic Shield, seismic discontinuities and the thermal regime in the Earth's crust, the physical and chemical composition of the deep crust and the transition from upper to lower crust, lithospheric geophysics, and to create and develop technologies for deep geophysical study. Drilling penetrated about a third of the way through the Baltic Shield of the continental crust, estimated to be around 35 kilometres (22 mi) deep, reaching Archean rocks at the bottom.[12] Numerous unexpected geophysical discoveries were made:
In 1992, an international geophysical experiment obtained a reflection seismic crustal cross-section through the well. The Kola-92 working group consisted of researchers from the universities of Glasgow and Edinburgh in the United Kingdom, the University of Wyoming in the United States, and the University of Bergen in Norway, as well as several Russian earth science research institutions.[19]The experiment was documented in a video recorded by Professor David Smythe,[20]which shows the drilling deck in action during an attempt to recover a tool dropped down the hole.
The drilling ended in 1995 due to a lack of funding.[11] The scientific team was transferred to the federal state unitary subsidiary enterprise "Kola Superdeep," downsized, and given the new task of thoroughly studying the exposed section.[6] In 2007, the scientific team was dissolved and the equipment was transferred to a private company and partially liquidated.[6]
In 2008, the company was liquidated due to unprofitability,[21] and the site was abandoned. It is still visited by sightseers, who report that the structure over the borehole has been partially destroyed or removed.[22]
The 12,262-metre (40,230 ft) deep Kola Superdeep Borehole has been the world's deepest borehole since 1979.[1][28] It was also the longest borehole in the world from 1979 to 2008. Its record length was surpassed in May 2008 by the curved extended reach drilling bore of well BD-04A in the Al Shaheen Oil Field in Qatar, which attained a total length of 12,289 metres (40,318 ft) but depth of just 1,387 metres (4,551 ft).[29][30]
Orbx proudly presents the DCS: Kola map, which covers northern Norway, Sweden, Finland, and the Russian Murmansk Oblast and parts of the Karelia region. The map also includes large areas of the Barents Sea and Norwegian Sea to the north and west, ideal for aircraft carrier operations. The Orbx DCS: Kola map is represented in its current-day state, with some allowance for late-Cold War military features and functionality.
The area's geopolitical significance stems from its largely ice-free Arctic ports, rich natural resources, important military installations and training areas, and past and present East-West tensions, the latter of which have significantly increased by the recent accessions of Sweden and Finland to NATO and Russian military operations.
The Russian portion of the map is home to its Northern Fleet and includes the mostly ice-free ports of Murmansk, Severomorsk, and the strategically important submarine bases of Polyarny. Also in this area are the important Russian air bases of Olenegorsk, Monchegorsk, Severomorsk, and others. The narrow land corridor from the Kola Peninsula towards the Baltic region has evolved into dense clusters of military airfields and installations, and has been listed as having the highest concentration of nuclear weapons, reactors, and facilities in Russia. This area, along with parts of central Finland adjacent to its border with Russia, is the focus of the early-access release.
The included regions of Norway, Sweden, and Finland also feature critical airbases, army bases, weapon and fuel storage depots, and training areas. Notable airports include Rovaniemi and Kemi-Tornio in Finland, Kiruna and Vidsel in Sweden, and Bodo, Andoya, and Lakselv in Norway. Sweden and Finland also feature multiple road runways, for defensive force dispersal of military aircraft.
Our F/A-18C is the culmination of more than 40 man years of intense research, technology development, art creation, and ground-breaking coding. The F/A-18C brings the first, true, multi-role fighter to the skies of DCS World with equally impressive air-to-surface and air-to-air capabilities.
The MiG-21bis is a delta wing, supersonic, fighter-interceptor jet aircraft. Much like the AK-47 became the everyman's rifle, the MiG-21 has been operated by more than 40 countries worldwide, and has enjoyed the longest production run of any modern jet fighter to date. The MiG-21, in all of its variants, has fought in wars stretching all the way from the Vietnam War in the 1960's to the modern day Syrian Civil War. Owing to its unique blend of versatility, ruggedness and maintainability, the MiG-21 remains in active service to this very day.

The 900x500 km map covers most of the eastern Mediterranean and includes the island of Cyprus, Lebanon, a large part of Syria up to the border with Iraq, parts of Israel, Turkey, and Jordan. The cities of Damascus, Nicosia, Tripoli, Latakia, Tartus, Homs, Aleppo, Hama, Palmyra, Haifa, Acre, Beirut and Adana are simulated, as well as unique constructions of world famous landmarks and historical monuments.
Geographically, the map covers moderately humid coastal areas in the west and mountains and arid desert landscapes in the east. The map recreates more than 200 historical and original structures in detail, as well as meticulously reproduces the military infrastructure - more than 100 military bases, training grounds, and checkpoints.
Especially for aviation fans, 51 airfields and heliports, including the international airports of Beirut Damascus and Larnaca, as well as the military airbases of Incirlik, Ramat David, Hmeymimim, Naqoura, and Akrotiri, are displayed at the highest level of detail.
The DCS: Sinai map is focused on the Sinai Peninsula, located between the Gulf of Suez and the Gulf of Aqaba with eastern Egypt to the west and southern Israel to the east. Since ancient times, it has been a strategic location rich in resources, nature, religion, and history. The map includes a variety of landscapes from deserts and mountains in the south to oasis and coastlines in the north. A significant point of interest is the Suez Canal - an artificial waterway connecting the Mediterranean Sea and the Red Sea that provides a shorter route between Europe and Asia. It marks a conditional border between Africa and Asia, which makes it politically significant for regional security and stability.
As much as a more advanced spawn system makes sense, the fixed slot system we have now isn't really out of place. Going to the other extreme where a player can slot anything anywhere could break missions. Just to use the example you provided, what is a IRIAF Tomcat doing on a carrier?
In any case have some curated form of advanced aircraft slot selection would be a very nice addition to have and it's relevant to any expansion of FC aircraft since it would be a shame to have to place separate slots for FC and FF versions of planes if a mission builder wants both.
As interesting as FC4 is, the only people who will be complaining are those getting into DCS, wondering why they can't fly their aircraft on multiplayer servers or the campaign they just bought for that aircraft; which in response is because they're entering late into the game for modules that are a decade old now, and the FF version is available...
Don't get me wrong, I'm all for FC aircraft for DCS; but it would make more sense to have FC versions as simultaneous releases. At the end of the day this isn't "new" content; and I guess since these are "unique" modules, it means the campaigns for the FF versions of these modules will have to be made unique as well if the campaign makers want to go down that road; as... holy smokes what a nightmare.
Imagine being a new player, buying something like the F5, flying it a bit, wanting to buy a campaign; you buy a campaign and you realize "you don't own this module" ..... because you have the FC version, not the FF version.
