China to build 3 Aircraft Carriers
NAVAL AVIATION: Chinese Aircraft Carriers
February 13, 2004: China is reported to be building, with the assistance of Russia, three aircraft carriers. Called Project 9935, the ships are probably based on a Russian Nevskoye Design Bureau design contracted for in 1994. An article published in China says that the final design decision was made by Hudong Shipyard, Shanghai in 1999. The ship is thought to be a modified Russian Admiral Ghorshkov carrier ¡°to Chinese specifications.¡± The ship is scaled up only about 6 percent.
Significant changes are the mounting of all point defenses and associated fire control systems, the mounting of a steam catapult on the angled flight deck, and modification/updating of the electronic suite. The Chinese article says that formal authorization to build a carrier was made in 1992. This apparently refers to legislation passed in that year which authorized ¡°two aircraft carriers.¡± Three covered graving docks were constructed at Shangahi and eyewitness reports indicate all three now have carriers building in them. Another source says the lead ship launched in 2002 and was expected to complete about 2004. The Chinese article says the lead ship should ¡°commission¡± in 2006 and that a ¡°battle group¡± should form ¡°by 2010.¡± These appear to be very conservative dates. Evidence strongly suggests that these ships are intended to be a technical surprise in several senses, including initial operating dates. The 2006 date is more realistic for the first carrier group. All three ships could be operational with battle groups by 2008-2010. The Chinese article says that maintenance facilities have been built at Shanghai, Dailan and Zhejiang. From this, and PLAN (Peoples Liberation Army Navy) organization, it appears each fleet will be allocated a single carrier.
The operational concept of these aircraft carriers differs from that of other nations. Aircraft carriers are not seen as the ¡°core¡± of the fleet. Rather submarines are. Instead, carriers have a primary fleet defense mission: to provide air and anti-submarine defense for surface forces, especially amphibious flotillas and logistic convoys. There is a significant secondary offensive strike mission, indicated by the mounting of SSMs and also inherent in the ability of fighter-bombers to carry offensive weapons. However, it appears that the carriers are not intended for distant power projection operations in the sense US CVNs are. Designed to operate near PLAN bases, they are to be offshore aviation platforms for a mainly land based naval air force. This may mean the aviation staying power of these ships is much greater than would normally be expected if they operated dedicated air groups. Further, in the absence of the need to buy aircraft and train crews for them, the unit cost of the carriers is lower than otherwise would be the case, while the cost of lost maintenance assets is also less, should a carrier be sunk. This is an imaginative, but very reasonable, application of naval air power to the essentially regional requirements of the PLAN.

Em se tratando de China, há sempre uma dose grande de desconfiança, no que se refere a esse tipo de notícia. Os fóruns chineses de discussão são apinhados de gente, mas infelizmente com uma enorme quantidade de fotos falsificadas e notícias otimistas demais. Sem falar que tudo isso é dificultado pela cortina-de-ferro, que não ficou em nada aliviada, mesmo com a abertura econômica.
Fica aqui, de qualquer forma, a notícia, para futuros acréscimos e comentários.

NAVAL AVIATION: Odd Composition of Chinese Carrier Aviation
February 18, 2004: There is no evidence that dedicated air groups are forming for the new PLAN (Peoples Liberation Army Navy) Project 9935 carriers. At the same time, all PLAN fixed wing fighter and attack pilots have been required to “carrier qualify” on a mock up of the flight deck of Australian carrier HMAS Melbourne. Given this mock up is at a PLAAF (Peoples Liberation Army Air Force) base, it may be that PLAAF pilots also have been practicing deck landings. The investment in the carrier project also involved building maintenance facilities, purchase of foreign aircraft carriers for study and the purchase of foreign aircraft carrier designs from Spain and Russia. These investments, combined with the reported laying down of actual hulls, combine with the lack of newly-formed air groups for the ships to imply that existing air units will be assigned to them.
In this context, the description of an “air group” for the new carriers is an entirely operational concept. Actual aircraft compliment will be determined by mission requirements and availability. But since “availability” is in the context of the fleet, as reinforced by other fleets and even by the air force or army aviation corps, it should result in a much greater likelihood even a large mission requirement can be met. Further, the ability to operate on a sustained basis should be much greater than would be possible for any air group dedicated to the ship.
It is probably useful to understand the direction in which Chinese air force organizations are moving. Aircraft are organized by types, with fixed wing combat aircraft mainly assigned to air divisions, while rotary wing and specialized fixed wing machines are assigned to independent squadrons. For fighter/attack types, air divisions are typically subdivided into two (formerly three) air regiments, which is the operational unit. Each regiment has two (formerly three or four) “flying units” with a nominal compliment of 10 aircraft, and a “maintenance unit” which actually “owns” all the aircraft of the regiment. In practice, a flying unit will operate 2, 4 or 8 aircraft, as required by a mission. Because the flying unit has 30-50 percent more pilots more than its nominal size requires, it is even theoretically possible that a 12 aircraft mission could be flown. PLAAF regiments also include a “training unit” which operates dissimilar as well as similar machines, including turbo-prop trainers on which unlimited flying is permitted. The PLAN appears to have concentrated training assets in a single air division, and it is not clear if there is also a training unit in each regiment. But in both cases, navy and air force fighter/strike air divisions with newer combat aircraft operate two air regiments each of which has two flying units (squadrons). A normal full scale regimental strike would involve up to 16 aircraft. This is the practical limit in the PLAN, because often the regiment only has 18 machines. But PLAAF regiments have 24 machines, so strikes of 20 or 24 aircraft are theoretically possible, especially on initial missions in any conflict. Helicopters tend to operate singly or in small detachments, as required.
Project 9935 ships appear designed to facilitate operations by two flying units simultaneously, with up to six helicopters (fueled and armed) in deck park in addition. The helicopter deck park is forward of the island structure. Helicopters in this location are stowed with rotors folded aft. The ships have the ability to have two fighters in position for take off runs up the angled deck plus four aircraft parked beside the long island structure (photographic evaluation of Adm. Kuznetzov operations during evaluation operations with Chinese and Indian observers). There is sufficient deck for up to four additional machines aft of the island. At the same time, a different flying unit would have access to the angled flight deck, and its catapult. If operated in this mode, both elevators are unavailable for use, being used as additional deck park space. More normally, one flying unit, plus some helicopters, might be operating. Apparently it is normal to use only the aft elevator, as trucks or helicopters normally are parked on the forward one. Even so, it is apparent a single Project 9935 ship could have elements of two regiments embarked, one on the flight deck, one on the hanger deck. As described above, a regimental strike would normally involve up to 16 aircraft.
A more typical operational aircraft compliment would probably involve a single regiment of fighter/attack aircraft. This would typically be 8 or 16 aircraft, depending on the mission requirement. One also would expect a compliment of 4-8 ASW helicopters, a detachment of 2 SAR (Sea Air Rescue) helicopters and a detachment of 2 AEW (Airborne Early Warning) helicopters. If the newest aircraft available to the Navy were assigned, one would expect the jets to be a carrier variant of the Su-30 (two batches of 20 ordered in 2003 for the PLAN) plus variants of the Ka-28 Helix helicopter. If older aircraft are operated, one might encounter J-6 (MiG-19), J-7 (MiG-21) or J-8 fighters (two engine mod of MiG-21), JH-7 (Chinese design) or Q-5 (mod MiG-19) attack aircraft, and Z-8 (Super Frelon) or Z-9 (Dauphin) helicopters. If Army Aviation Corps helicopters were embarked, the most likely would include Mi-181 transports and the attack variant of the Z-9.
PLAN literature concludes that it takes 8 to 10 cruise missile hits to disable a US CVN (nuclear powered carrier). At the same time, they require an average of 4 cruise missile hits on half the escorts of the enemy battle group. To achieve this, they estimate 70 to 100 cruise missiles should be launched on three or more threat axis. If a carrier were to participate in such an attack, it and its escorts would launch 24-40 cruise missiles as one component while an air regiment would deliver about 32 cruise missiles on another axis. The remainder would have to come from surface action groups and submarines. It is very difficult to coordinate launching such multiple attacks simultaneously. The critical issue is detecting and tracking the enemy target task force. If this can be achieved, probably by satellite or MR aircraft, and if all elements of the attacking force could reach firing position before being engaged, this (Russian) attack concept is potentially effective.

A China está construindo, com assistência da Rússia, três porta-aviões chamados projeto 9935. O navio deve ser baseado no Admiral Ghorshkov com especificações chinesas, como o aumento do tamanho em 6 %. O navio foi autorizado em 1992 e deve ser comissionado em 2006. Os navios terão missão de defesa antiaérea e anti-submarina das forças de superfície como comboios logísticos e forças de desembarque. A capacidade ofensiva será secundária. Não há evidencias de uso a distancia para projeção de poder.

Então, isso não é um porta-aviões. É uma "pista de pouso aquática".
Interessante pensar em qual será o significado desse conceito.
