These are milestones marking the large repair capacity of fighter jets and recognizing the outstanding development of Vietnam’s aviation engineering industry. Su-27 fighter at A32 Factory. In addition, the factory also repaired tens of thousands of spare parts and equipment for the units; produce hundreds of thousands of aviation technical materials. Besides, it also repairs special motorcycles; participate in the repair of weapons of the Air Defense units, Navy. Recently, the High-Tech Center went into operation, marking a great step forward of the unit. From here, A32 Factory can improve repair capacity to regional and international level. The People’s Army newspaper also said that in the past time, the A32 Factory has successfully repaired and put into flight 30 aircraft of all kinds, ensuring good technical indicators and handed over to the units. The factory also replaced 4 oil barrels and repaired and enhanced the Su-30MK2 aircraft fuel system; manufactures 188 fuel pipes, special high-pressure gas pipes, special air defense lights for TZM cars… In addition, A32 also repairs and replaces parts and components for air defense units; repair the hydraulic system that controls the rotation of the radar antenna on the ship; manufacturing and mechanical processing of components for the X51 Factory and the General Department of Defense Industry. To meet the requirements and tasks of aeronautical engineering repair, the factory has promoted the spirit of self-reliance, self-reliance, collective intelligence, designed hundreds of mechanical drawings for processing and manufacturing. components, spare parts, technical materials for repair and production. Not only that, but the factory also compiled many documents, including bilingual documents, especially the set of major repair technology, increasing the service life of Su-22 and Su-27 aircraft. Vietnam’s success has surprised the Russian side, in a recent article titled “Su 27/30: Vietnam will repair itself at home”, Russian defense magazine VPK said that Vietnam has self- Repairing and upgrading Su-27 and Su-30 fighters at the new factory in Da Nang. Accordingly, Vietnam is building capacity for basic maintenance and repair of Su-27 and Su-30 fighters, to avoid sending aircraft abroad. To implement this program, Vietnam recently put into operation the A32 defense plant in Da Nang. “The self-repair and upgrade of the aircraft in the country will significantly increase the operational readiness of the fighter,” the source confirmed. According to VPK, to get this result, A32 Factory sent dozens of staff to train abroad. Currently, the factory has successfully repaired the failures of this modern fighter on its own. Each workshop repairs a technical array with over 10,000 different components that require extreme caution, precision, and meticulousness.

Flight preparation of the 937th Regiment. The highlight in the World War II movement of the 937th Regiment in recent years is that the pilots have tried their best to review the theory, practice the sand table, master the basic situations, emulate to complete the flight lessons and integrate into the field. safe flight time. The team of technicians promotes practical application initiatives, thoroughly overcomes breakdowns, and ensures the best technical condition for the aircraft… In particular, in rehearsals, participating in bombing flights, and firing live ammunition on land and at sea during the day and at night, the regiment always focused on launching emulation, building the will and determination for all officers and combatants. doctors, especially pilots and technicians. With the task of protecting the Spratly Islands and the southern waters of the country, the 937th Regiment regularly trained not to be surprised in any situation. The mission to fly to protect Truong Sa began on October 19, 1989, when at Phan Rang airport, pilots Vu Kim Dien and Nguyen Van Than successfully completed the first mission flight on the Sukhoi Sukhoi Sukhoi Aircraft. -22M4 to Truong Sa. At the end of October 1989, Su-22M4 continued to successfully carry out live fire at Hon Ty shooting range. After this event, the 937th Regiment was officially assigned by the Commander of the Air Defense Forces to protect the Truong Sa archipelago and the southern maritime economic zone of the country. Since then, in addition to the Su-22M4 fighter, there are also Su-30MK2 fighters and generations of pilots of the 937th Regiment, still the main force in charge of the role of patrolling and protecting the Truong Sa archipelago.

Pilot Wang Zunxi (a fairly well-known PLAAF officer) in an interview with China Central Television (CCTV 7) gave a very remarkable point of view. According to the veteran pilot, the multi-purpose fighter J-16 manufactured in Shenyang Aircraft Corporation and is being massively employed for PLAAF combat units of generation 4 ++. “J-16 fighter jets (including the J-16D electronic warfare version) have surpassed Russia’s Su-30 series heavy multi-role fighters in almost all tactical specifications. “. “The superiority shown in both avionics and electrodynamic properties, the radar reflection area reduction coefficient (RCS), the J-16 retains only the aerodynamic layout of the airframe”, pilot Vuong said clearly. Faced with the above situation, the Russian press stated that in order to seek export contracts or bring high morale and psychological state to the soldiers, the weapons manufacturers used very sophisticated promotional tools and are not always objective. Russian military experts rebuttal when emphasizing that the Chinese pilot is comparing the technical specifications of the electronic equipment on the Su-30MKK and Su-30MK2 fighters that are somewhat out of date. These fighters were supplied to the PLAAF 20 years ago, and they are actually significantly inferior to the J-16 when facing exercises (both for surface attack and long-range interception missions). ). The reason is that China’s Su-30 integrates the N001VE passive phase array radar (PESA), which ensures the realization of “truncated” synthetic aperture and “truncation” (SAR) mode with low resolution. , only allows the detection and classification of targets with large RCS parameters. In addition, the capacity and anti-interference ability of the N001VE radar is quite low, it can only catch the 1m2 RCS aerial target, 75 – 80 km away in case the enemy does not use electronic countermeasures. In fact, the J-16’s high energy and anti-interference active phase array (AESA) radar has a target capture range with 1 m2 RCS from 130 to 150 km, and high anti-interference ability, range is only slightly reduced in a highly noisy environment. This is due to the presence in the electronic architecture of the advanced AESA radar, which consists of more than 1,500 transceiver modules, each equipped with an individual arsenide / gallium nitride microwave transistor. Moreover, this type of radar is also capable of operating in synthetic aperture (SAR), reverse synthesized aperture (ISAR) and tracking ground targets moving in real time. Although the equipment for the J-16 is very advanced, the Russian side thinks that it is necessary to compare the J-16 with more modern modifications, for example the Su-30SM2 variant is about to enter service. Although the N035 Irbis radar that will equip the Su-30SM2 of the PESA class may be significantly inferior to the J-16’s AESA radar in terms of interference resistance, the capacity is higher (providing target acquisition range. with 1 m2 RCS at a distance of 250 – 270 km). With the N035 Irbis radar, the Su-30SM2 will have the ability to “foresee and shoot before” the J-16 in a direct confrontation situation, especially when Russia is still completing the long-range air-to-air missile “product. 180 ”. But it must be noted that the Su-30SM2 is still on paper, while the J-16 has been on duty for many years and there is no guarantee that the Russian fighter really possesses outstanding features. as they still publish.
