Question: The Kamov V-80 eventually evolved into that single seat Russian attack helicopter?

Context paragraphs:
Kamov Ka-92: The Kamov Ka-92 is a high-speed coaxial helicopter design proposed by Kamov of Russia in competition with the Mil Moscow Helicopter Plant for a $1.3 billion project by the Russian government for development of a high-speed helicopter.

Bell AH-1 SuperCobra: The Bell AH-1 SuperCobra is a twin-engine attack helicopter based on the United States Army's single-engine AH-1 Cobra.  The twin Cobra family, itself part of the larger Huey family, includes the AH-1J SeaCobra, the AH-1T Improved SeaCobra, and the AH-1W SuperCobra.  The AH-1W, the backbone of the United States Marine Corps's attack helicopter fleet for decades is being replaced by the next generation Bell AH-1Z Viper attack helicopter.

Kamov V-80: The Kamov V-80 was a design study designation for an attack helicopter that eventually evolved into the single seat Kamov Ka-50 family of aircraft.

Mil Mi-28: The Mil Mi-28 (NATO reporting name "Havoc") is a Russian all-weather, day-night, military tandem, two-seat anti-armor attack helicopter.  It is an attack helicopter with no intended secondary transport capability, better optimized than the Mil Mi-24 gunship for the role.  It carries a single gun in an undernose barbette, plus external loads carried on pylons beneath stub wings.

KMGU: KMGU (Russian: "Контейнер малогабаритных грузов унифицированный, Unified Container for Small-sized Load)" is a Soviet munitions dispenser similar to the British JP233 and the German MW-1.  It can be carried by most Soviet and Russian attack aircraft, including the MiG-23, the MiG-27, the MiG-29, the Su-22, the Su-24, the Su-25, the Su-27, the Su-30, and the Su-34 and the Mi-24, Ka-50 and the Ka-52 attack helicopter.  The cylindrical aluminum fuselage is divided into 8 sections, each has its own pneumatically opened doors.  It can be filled with:

16 Squadron SAAF: 16 Squadron SAAF is an attack helicopter squadron of the South African Air Force (SAAF).  It was originally formed in World War II as a maritime patrol squadron, however, over the course of the war it was disbanded and reformed a number of times, operating a number of different types of aircraft.  It was finally disbanded in June 1945 and was not re-raised until 1968 as a helicopter squadron.  In the late 1980s the squadron took part in the conflict in Angola before being disbanded again in 1990.  It was raised once more in 1999 and it is currently operating the Rooivalk attack helicopter.

Kamov Ka-50: The Kamov Ka-50 "Black Shark" (Russian: "Чёрная акула"; "Chornaya Akula" , NATO reporting name: Hokum A) is a single-seat Russian attack helicopter with the distinctive coaxial rotor system of the Kamov design bureau.  It was designed in the 1980s and adopted for service in the Russian army in 1995.  It is manufactured by the Progress company in Arsenyev.  It is used as a heavily armed scout helicopter.  It is the world's first operational helicopter with a rescue ejection system.

Lockheed AH-56 Cheyenne: The Lockheed AH-56 Cheyenne was an attack helicopter developed by Lockheed for the United States Army.  It rose from the Army's Advanced Aerial Fire Support System (AAFSS) program to field the service's first dedicated attack helicopter.  Lockheed designed the Cheyenne using a four-blade rigid-rotor system and configured the aircraft as a compound helicopter with low-mounted wings and a tail-mounted thrusting propeller driven by a General Electric T64 turboshaft engine.  The Cheyenne was to have a high-speed dash capability to provide armed escort for the Army's transport helicopters, such as the Bell UH-1 Iroquois.

Advanced Attack Helicopter: The Advanced Attack Helicopter (AAH) was a United States Army program to develop an advanced ground attack helicopter beginning in 1972.  The Advanced Attack Helicopter program followed cancellation of the Lockheed AH-56 Cheyenne.  After evaluating industry proposals, the AAH competition was reduced to offerings from Bell and Hughes.  Following a flight test evaluation of prototypes, Hughes' YAH-64 was selected in December 1976.

Armed helicopter: An armed helicopter is a military helicopter equipped with aircraft ordnance.  Most commonly, it is used for attacking targets on the ground.  Such a helicopter could be either purposely designed for a ground-attack mission—in which case it would be more specifically categorized as an attack helicopter—or may have been previously designed for other uses, such as utility, air cargo, aerial reconnaissance, etc., with the weapons mounts being modifications, rather than part of the design of the helicopter.  The purpose of the modification to an armed helicopter configuration can be field expediency during combat, the lack of military funding to develop or purchase attack helicopters, or the need to maintain the helicopter for missions that do not require the weapons.
