Fighters Su-27/30 family in the Air Force in Vietnam

It can be assumed that the origins of Vietnam’s military modernization program faces challenges balancing China’s military development, and between Vietnam and China there is a long-standing border dispute, which has recently added the disputed territories in the South China Sea.


By 1992, the Chinese Air Force were all booked in the previous year 26 fighter Su-27SK/UBK. This contract has sounded a warning to the Vietnamese leadership, resulting in the two years since the official supplier of the Russian company "Rosvooruzhenie" was awarded a contract worth $ 200 million for the supply of five Su-27SK and Su-one 27UBK. These fighters were the first multi-role fighter Vietnamese Air Force (the official name of the Khong Quan Nham Dan Viet Nam). The price of the contract also included training of pilots and ground personnel in Russia.

The first two Vietnamese Su-27 were obtained in May 1995, the remaining profits in Vietnam by the end of 1996 they all became part of the 937 th Fighter Regiment «Hau Giang» (named in honor of one of the provinces of South Vietnam), which was established May 30, 1975, one month after the end of the Vietnam War. The regiment is based at the airport Rank Pham (Pham Rang).

In December of 1996 to the first six Su-27 added a new party, which included two Su-27SK and four Su-27UBK. He strengthened the Vietnamese defense capabilities in the face of 22 Chinese Su-27SK/UBK received shortly before that year. The new contract was for $ 120 million, and two single plane were taken to the Vietnamese KnAAPO in October 1997 After three months on board a military transport aircraft An-124 were delivered in Phan Rang, where there was a training center for Vietnamese the Air Force. Already there have been reassembled planes flying around, and then transferred to the 935 IAP «Dong Nai», which was created on the same day as the «Hau Giang». Currently, 935 IAP is stationed at the airport in Bien Hoa, where he was transferred from Kam-Rani.

These were followed by the first pair of combat-capable fighter aircraft that were delivered to Vietnam in December 1997, but two "doubles" with serial numbers 8524 and 8525 after five days were lost in the crash of the same AN-124 (w / o "08 black "), which fell after stopping three of its four engines. He crashed into a residential area near the factory airfield IAPO "Irkutsk-2", from which "Ruslan" made his takeoff. As a result of the disaster killed 23 people on board and 70 on the ground, and the cargo was lost. Sioux 27UBK were insured against loss, and to replace them, fighters with serial numbers 8526 and 8527 were delivered six months later, in June 1998, one of the Su-27SK (6007) crashed in 1998

The Su-27SK is a modification of the Su-27, developed for delivery to foreign customers. It differs from the one for the Russian Air Force reinforced chassis, increased take-off weight and avionics with reduced performance, although it remains a remote control system of the CDS-10. It also established weapon control system WCS-27, the main element of which is the N001 radar "Sword" and the electro-optical sighting system OEPS-27. RADAR allows the Su-27SK to produce two simultaneous attack air targets, and lead tracking 10 targets. Radar «Slot Back» (NATO code for the radar "Sword") is the detection range of 80 km in the forward hemisphere m 30-40 km — in the back for a 3 EPR m2. Provides detection and tracking of air targets, both in free space and on the background of the land, recognition and identification of the most dangerous of the tracked targets and selection of the attack, the interception of signals of enemy electronic warfare systems, and pitch commands missiles "air-to-air" after their launch . All of these functions may be implemented in the forward sector of 120 ° and at altitudes of 50 m to 27 km.

Optronic sighting station OEPS-27 includes teplopelengator with day and night channels, and a laser rangefinder. The station provides target detection by the thermal contact. Target detection range class "fighter" in the range of 15-50 km. OEPS radar and can share data and supplemented by a helmet-mounted target designation system NSTS-27, with which homing missiles can be directed toward the target by turning the pilot’s head or OEPS on target in azimuth of + / — 60 ° and the angle of -15 / +60 °. All the information about the target can be transmitted via the bus communication "Spectrum", which also allows you to receive instructions from AWACS aircraft, and then they entered the automated control of the aircraft and weapons.

Although the Su-27SK was designed as a "pure" fighter, they can be used unguided weapons "air-land" weighing up to 8 tons, which can be hung on 10 hardpoints. The range of weapons includes NUR and svobodnopadayuschie bombs that can be used with the weapon control system FCS-27 in manual or automatic mode.

The Su-27SK mounted turbojet engines AL-31F afterburning thrust at 12.5 tons, which allows speeds of up to 1,380 km / h at sea level and accelerate up to 2500 km / h in five minutes. The aircraft can fly at a speed of 1,400 km / h indefinitely at altitudes between 9 and 18.5 km, which is the maximum ceiling of the aircraft. In spite of its performance characteristics of the Su-27SK stunning performance on the flying range — 1370 km at sea and 3,676 miles when flying at high altitude. SU-27 has a roll rate at 180 ° per second turn rate is 21 ° per second.


The threat from the Chinese Su-27 gradually increased — in December 1998 collected the first J-11 fighter jets that were licensed version of the Su-27SK. Aviation company Shenyang Aircraft Company planned to release at least 200 of these aircraft.

In May 1999, the first flight of the Su-30MKK that could be used precision-guided weapons, which have been deprived of Vietnamese Su-27. Three years later, under the requirements of the PLA Navy had developed a version of the Su-30MK2 — among its improvements it was possible to use anti-ship missiles X-31, which seriously threatened the sovereignty of Vietnam over the surrounding maritime areas. Between February and August 2004, the PLA Navy received 24 Su-30MK2.


Russia soon found that she could expand the market for its Su-30MK. China has ordered Su-30MKK/MK2, India Su-30MKI and Su-30MKM Malaysia. Since KnAAPO is a traditional supplier of Vietnamese Air Force, the plant has developed a slightly modified version of the Su-30MK2, which corresponded to the requirements of the Vietnamese, which was called the Su-30MK2V.

In December 2003, a contract was signed to supply four of these fighters in the amount of $ 100 million that had been shipped to the customer 11 months later. In January 2009, signed a new deal worth $ 500 million for the supply of an additional eight Su-30MK2V, four of which were obtained by the Vietnamese in June 2011, fi
ve months later, followed by a new order for 12 aircraft valued at $ 1 billion but they will be delivered no earlier than 2012-2013 years.


Sioux 30MK2V operated a modified version of the remote control system of the CDS CDS-10-10U. The control system can be mounted weapons new electronic modules depending on the customer’s requirements, and it is composed of two subsystems, the SUV-RE (responsible for the use of systems of "air-to-air radar and integrated with N011VE/RLPK and RL-30) and the SUV-P ( applied to the system of "air-land", consists of a selection of weapons MSA-30PK, as well as a satellite navigation system NAVSTAR / GLONASS A-737).

N001VE radar can detect a target class "fighter" at a distance of 110 km, aircraft carriers and surface-fast boat is found at a distance of 250 km and 70, respectively. The aircraft can perform nine tasks in the "air-to-air" (including aerial reconnaissance) and 10 tasks "air-land" (including monitoring the atmosphere above the water). Finally, the radar can simultaneously track 10 targets and the use of weapons by air or by two to four ground targets.

N001VE space can scan through 120 ° horizontally and 110 ° vertically, RL-30 has a maximum range of 90 km. As in the case of the Su-27SK both systems can communicate with each other, except that they are complemented with a helmet-mounted target designation system "Sura-K", which has a field of view of + / — 60 °, the Su-30MK2V running the same O interconnect " Spectrum ".

Thanks to the AL-31F engines 3 series having the same cravings, Su-30MK2V develops the same speed as the Su-27SK at sea level, but at the height of the speed is limited to 2120 km / h, and the ceiling was reduced to 17.3 km. With a maximum fuel capacity of the Su-30MK2V has a range of 1,300 km at sea level and at an altitude of 3000 km. Allowable ranges overload 9 / -3 units with the same load as that of the Su-27SK, but which may be suspended on suspension points 12.


The Su-27 is primarily used as an air defense interceptor. In a typical case, the two pilot are duty room for 24 hours, to take their place in their respective planes for the alarm. There is also a state of immediate readiness, when both members of the crew are in the cockpits of airplanes waiting for clearance to take off, which is issued by the Air Force headquarters in Hanoi, where one of the two radar "Sky-NE". These systems can detect up to 256 targets simultaneously in height from 50 m to 27 km, and ranges from 50 to 330 km.

Besides Vietnamese Su-27/30 used for operations to isolate the battle area. This was demonstrated in July 2011, when the aircraft 935 th and 937 th IAP made 37 sorties, during which the "Dry" dropping bombs and rockets were allowed in response to clashes with Chinese forces in the South China Sea.

At the beginning of July this year Most fighter "Su" from Bien Hoa Air Base relocated tho Juan (Tho Xuan), which deployed the 923rd Fighter-Bomber Regiment, also known as "Ian Polk", which are in service with fighter-bombers Su-17/22M4/UM -3K. This could mean that the Air Force in Vietnam are going to equip the Su-30MK2V next batch third squadron.
