Meet the New PLAAF

אנקדוטות נבחרות
By far the most significant development for the PLAAF has been the shift from a large force of outdated, 1960s-vintage fighters to a smaller, more capable force. Today’s PLAAF features several fighters brought into service in the 2000s. Some were purchased from Russia, while others were built under license by China’s two major combat aircraft manufacturers, Shenyang Aircraft Corp. and Chengdu Aircraft Industry Group. Together they total nearly 400 aircraft whose aerodynamic characteristics and armament may be close to par with US fighters, excepting the F-22.
The Pentagon’s 2012 China military report tallies 1,570 fighters, 550 bombers, 300 transport aircraft, plus another 1,450 older aircraft in the PLAAF inventory. However, the report does not offer a thorough order of battle.
Just as important are improvements in air-to-air missile technology. China once relied on imitations of the AIM-7 family but now has sophisticated short- and medium-range air-to-air missiles in its inventory. The principal types are the R-27/AA-10 semi-active radar/infrared missile; the infrared guided R-73/AA-11 with a range of 18.6 miles; and the active radar homing R-77/AA-12 with a range estimated at 31 to 50 miles. Three of the four main types of fourth generation fighters—the J-10, J-11, and Su-30—carry the long-range advanced air-to-air missile R-77/AA-12 and the indigenous variant PL-12. So does the J-8, bringing the number of potential missile platforms to 776.
The J-20’s front aspect in particular shows many external stealth design curves and features similar to the F-22. From side and rear aspects, the resemblance fades, due to the block fuselage, canards, protruding engines, and thin vertical stabilizers. For now, it is equipped with Russian-built AL-31F engines. The size of the J-20 suggests it could carry internal fuel plus a large bomb bay suited to known Chinese missile inventories including cruise missiles and extended range air-to-air and anti-ship missiles. RAND analyst David A. Shlapak estimated it might be capable of supercruise, i.e., reaching Mach speed without afterburner.
The DH-10 cruise missile shows Chinese military air attack development in microcosm. The ground-launched missile was first deployed in small numbers in 2008. By 2009, the number of deployed DH-10s was pegged at up to 350 missiles. Current assessments suggest China has between 200 and 500 DH-10 missiles with a 930-mile range. What portion of the inventory consists of air-launched cruise missiles is not known. Still, this growing capability gives China the ability to create havoc in the air over the Pacific. Estimates suggest the H-6M carries four anti-ship missiles, while the H-6K carries six cruise missiles. China has the option of combining its most advanced H-6 bomber variants with air-launched DH-10 cruise missiles, theoretically increasing the missile’s reach to more than 2,000 miles.
The PLAAF is also tasked with ground-based air defense. The PLAAF took delivery of its first SA-2s in 1958 and has since built a formidable arsenal of legacy SAMs, advanced Russian systems, and their own indigenously modified HQ-9s. Like fighter aircraft, the PLAAF surface-to-air missile fleet has a highly modernized elite force of about 192 launchers on top of a bedrock of approximately 490 legacy launchers.
Of particular concern are the 192 SA-20, SA-10, and HQ-9 type launchers. The SA-10 range is about 50 miles, but the SA-20 variants have ranges between 93 and 124 miles.
Liaoning differs from the US Navy’s Nimitz-class carriers in several ways. Launch operations take place from the primary deck where a 12-degree ski jump lofts fixed wing aircraft into the air. Arresting wires recover aircraft. Liaoning’s hull was originally designed for substantial self-defense, with automatic deck guns comparable to the Phalanx, vertical launch tubes for long-range air defense, and ship-to-ship missiles. Full flight operations have not yet been observed. However, a Shenyang J-15 fighter completed a touch-and-go landing drill on Liaoning on Oct. 12, 2012, and in late November a pair of J-15s made successful arrested landings before launching again from the carrier. The J-15 is a Chinese-built derivative of the Su-33 designed for carrier operations. China acquired one Su-33 (an upgrade of the Su-27) from Ukraine in 2001. Analysts Phillip C. Saunders and Joshua K. Wiseman from the National Defense University expect the J-15 to enter full rate production between 2015 and 2017, which "will give China a capable fourth generation fighter that can be operated from aboard aircraft carriers." The carrier class was originally designed to deploy with some 30 fixed wing fighters and an additional complement of helicopters. That deck mix will add both prestige and local control of the air.
Significant holes remain in the PLAAF modernization. Foremost among these is its small air refueling fleet. China has perhaps eight Il-78 tankers and may have converted up to a dozen H-6 bombers to refueling status
