- Mi-26TZ. Modification of tanker, created on the Rostov branch in 1988. for the supply with the fuel of aircraft, helicopters and ground-based technology. The series version of this machine rose into air on February 1, 1996. In the cargo compartment is established the set of fueling equipment for modular construction, which consists of: two carts with the fuel tanks, the pumping units and the control panels; carts with four distributing sleeves for the aviation, ten times for the diesel fuel and by the counters of pumping. The volume of transportable fuel is 14000 liters, lubricants - 1040 liters, the time of development and coagulation - from 10 to 25 min. Mi-26TZ: Fuel tanker fuel and lubricants are pumped through 4x 60-meter long refueling nozzles for refueling aircraft, and 10x 20-meter long hoses for refueling ground vehicles. Fuel transfer rate is 300 liters/minute for aviation fuel, and 75-150 liters/minute for diesel fuel. The refueling system can easily be removed to allow the aircraft to perform transport missions.
- Mi-27. In the correspondence with the government decision on the base Mi-26 in 1988, the air control post, intended for the control of the military operations of armies of combined arms was built at the Rostov helicopter plant. The cargo compartment was divided in the salon of operations group with six by work sites, the technical and living quarters.
- Mi-26NEF-M. ASW version with search radar in undernose faired radome, extra cabin heat exchangers and towed MAD housing mounted on ramp. In 1990 one Mi-26 was re-equipped by Rostov branch MVZ im. M.L.Milya into the long-range antisubmarine helicopter for the transportation during the external suspension of the hydroacoustic station of search and detection of submarines.
- Mi-26P. Boundary modification for the flights in the high latitudes, built in 1992. and characterizing by special communication equipment.
- Mi-26P. Transport for 63 passengers, basically four-abreast in airline-type seating, with centre aisle; lavatory, galley and cloakroom aft of flight deck.
- Mi-26TM. Flying crane, with gondola for pilot/sling supervisor under fuselage aft of nosewheels or under rear-loading ramp. In 1992. the specialists of joint stock company Rrostvertol together with the designers of joint stock company Rostov-mils (former Rostov branch MVZ im. M.L.Milya) proposed assembly version Mi-26[T], equipped with the additional easily removable cab of pilot-operator. Cab is arranged from below the center fuselage, or instead of those dismantled of rear ladder and loading doors.
- Mi-26PK. Flying crane (kran) derivative of Mi-26P with operator's gondola on fuselage side, next to cabin door on port side. Joint stock company MVZ im. M.L.Milya developed in 1997 this crane-assembly modification Mi-26PK. The additional easily removable cab of pilot-operator is arranged on it from the side on the spot the left front door. Cab is equipped with the mechanical system for control. Pilot-operator can be arranged in it as along the flight, so against the flight.
- Mi-26TP. Firefighting (pozharnyi) version with internal tanks able to dispense up to 15,000 litres (3,962 US gallons; 3,300 Imp gallons) fire retardant from one or two vents, or 17,260 litres (4,560 US gallons; 3,796 Imp gallons) of water from an underslung VSU-15 bucket, or from two linked EP-8000 containers. Unique load capacity Mi-26 predetermined the exceptional attractiveness of this rotary-wing work horse for the re-equipment into the carrier of the means of extinguishing and localization of extensive fires, specials-technician landing. By the specialists of joint stock company Rrostvertol together with Mmilevskimi designers is created in recent years a number of fire-prevention helicopters Mi-26 of different modifications, including the apparatus, transmitted in 1999. To administration of the fire protection [GUVD] of Moscow. It is equipped with the spillway device VSU-15, which is soft special capacity by capacity 15 tons, transported by helicopter during the external suspension.
- The specialists of MVZ im. M.L.Milya under the general management of design project leader A.G.Samusenko developed projects of re-equipment of the Mi-26 as an anti-mine trawler, flying hospital, passenger helicopter- salon, fire-prevention helicopter with the water-jet gun and the rods of water intake, helicopter of ecological reconnaissance, and also project of more load-lifting modification Mi-26M, equipped with glass-plastic blades, new engines D -127 and more advanced flight complex. In the 1980s the OKB studied the possibility of designing on the base of dynamic system Mi-26 of heavy lift helicopter Mi-26K with those changes, by analogy with the helicopter Sikorsky S-64, the fuselage and the chassis. However, the economic difficulties of the following decade prevented the practical embodiment of these concepts. Among the unaccomplished proposals on the modernization Mi-26 it is necessary to mention the project "of the doubling" of power plants according to transverse diagram for an increase in the load capacity, which was being examined since 1972 as one of the versions of program Mi-12M. The work on it was ended at the end of the 1970's in connection with the beginning of the design of giant Mi-32.
- The 1990 edition of US Department of Defense's Soviet Military Power stated "New variants of `Halo' are likely in the early 1990s to begin to replace `Hooks' specialised for command support." Two prototypes were reported to have been built, with designation Mi-27. These have new antennas along lower `corner' of fuselage, blade and box-type and with long folded masts which are horizontal in flight, vertical when deployed on ground. Prototype wears Aeroflot color scheme.
- In 1999 for creation by one of the modifications Mi-26 the colleagues of joint stock company MVZ im. M.L.Milya A.G.Samusenko and V.S.Ryabinin were honored the State Prize RF.
- Mi-26M: Upgrade under development; all-GFRP main rotor blades of new aerodynamic configuration, new ZMKB Progress D-127 turboshafts (each 10,700 kW; 14,350 shp), and modified integrated flight/nav system with EFIS. Transmission rating unchanged, but full payload capability maintained under `hot and high' conditions, OEI safety improved, hovering and service ceilings increased, and greater maximum payload (22,000 kg; 48,500 lb) for crane operations.
