US Air Force F 35A and F 16s Fighters Formation Flight

F-35 is Liaoning's worst nightmare, says Global Times

The US F-35 Joint Strike Fighter is capable of combating China's first aircraft carrier, the Liaoning, reports Huanqiu, the website of China's nationalistic Global Times tabloid.In a hypothetical aircraft carrier battle between China and the United States, the main fighter jets would include the United States' F-35C fifth-generation multirole fighter developed by Lockheed Martin and China's J-15 carrier-based jet developed by Shenyang Aircraft Corporation.

The F-35 is equipped with extremely powerful offensive capabilities for both land and sea combat, with a weapons load of eight tonnes and the capacity to carry four AIM20C and AIM-9X mid-range and short-range air-to-air missiles.In an attack on the Liaoning the F-35 could carry joint strike missiles developed in Norway, which have a range of 290 kilometers. The J-15, on the other hand, could carry two YJ8-3 anti-missiles with a range of only 180 km.

In terms of radar technology, the US has the clear upper hand with its AN/APG-81 AESA radar developed by Northrop Grumman, which has a thousand transceivers with the ability to simultaneously search for 23 moving targets, including 19 targets in just 2.4 seconds, after which it would turn to tracking mode.Even against China's J-20, the stealth, twin-engine fifth-generation fighter aircraft prototype being developed by Chengdu Aerospace Corporation, the F-35 would still be the first to detect its opponent due to its superior radar.

Observers are asking whether the Japan Air Self-Defense Force will make modifications to its F-35A jets to use the domestically developed AAM-4 and AAM-5 medium-range active radar-guided air-to-air missiles or if they will use US missiles given the differences in dimensions.
The problem for Japan is the cost of the F-35A, which could mean fewer aircraft if the price continues to rise. The price of the F-35A was US$111.6 million back in 2010, while the F-35B cost US$109.4 million and the F-35C was priced at US$142.9 million; since then the average price of one F-35 has risen to as high as US$228 million, according to some sources.

New U.S. Stealth Jet Can’t Hide From Russian Radar

The F-35 Joint Strike Fighter—the jet that the Pentagon is counting on to be the stealthy future of its tactical aircraft—is having all sorts of shortcomings. But the most serious may be that the JSF is not, in fact, stealthy in the eyes of a growing number of Russian and Chinese radars. Nor is it particularly good at jamming enemy radar. Which means the Defense Department is committing hundreds of billions of dollars to a fighter that will need the help of specialized jamming aircraft that protect non-stealthy—“radar-shiny,” as some insiders call them—aircraft today.These problems are not secret at all. The F-35 is susceptible to detection by radars operating in the VHF bands of the spectrum. The fighter’s jamming is mostly confined to the X-band, in the sector covered by its APG-81 radar. These are not criticisms of the program but the result of choices by the customer, the Pentagon.

To suggest that the F-35 is VHF-stealthy is like arguing that the sky is not blue—literally, because both involve the same phenomenon. The late-Victorian physicist Lord Rayleigh gave his name to the way that electromagnetic radiation is scattered by objects that are smaller than its wavelength. This applies to the particles in the air that scatter sunlight, and aircraft stabilizers and wingtips that are about the same meter-class size as VHF waves.The counter-stealth attributes of VHF have been public knowledge for decades. They were known at the dawn of stealth, in 1983, when the MIT’s Lincoln Laboratory ordered a 150-foot-wide radar to emulate Russia’s P-14 Oborona VHF early-warning system. Lockheed Martin’s Fort Worth division—makers of the F-35—should know about that radar: they built it.

Making a plane VHF-stealthy starts with removing the target’s tails, as on the B-2 bombers. But we did not know how to do that on a supersonic, agile airplane (like the F-35 is supposed to be) when the JSF specifications were written.Neither did the technology to add broadband-active jamming to a stealth aircraft exist in 1995. Not only did stealth advocates expect jamming to fade away, but there was an obvious and (at the time) insoluble problem: To use jamming you have to be certain that the radar has detected you. Otherwise, jamming is going to reveal your presence and identify you as a stealth aircraft, since the adversary can see a signal but not a reflection.

We can be sure that onboard jamming has not been added to the F-35 since. Had the JSF requirements been tightened by one iota since the program started, its advocates would be blaming that for the delays and overruns.What the JSF does have is a jamming function—also known as “electronic attack,” or EA, in militaryese—in the radar. It also has an expendable radar decoy—BAE Systems’ ALE-70. Both are last-ditch measures to disrupt a missile engagement, not to prevent tracking.

JSF’s planners, in the mid-1990s, were close to correct when they calculated that low-band stealth and limited EA, combined with passive electronic surveillance for situational awareness, would be adequate at service entry. But they expected that the F-35 would reach squadrons in 2010, and China’s military modernization was barely imaginable.The threats of the late 2010s will be qualitatively different. Old VHF radars could be dealt with by breaking the kill chain between detection and tracking: they did not provide good enough cueing to put analog, mechanically scanned tracking radars on to the target. Active electronically scanned array (AESA), high-power VHF radars and decimeter- and centimeter-wave trackers are more tenacious foes.

Last August, at an air show near Moscow, I talked to designers of a new, highly mobile counterstealth radar system, now being delivered to the Russian armed forces. Its centerpiece was a 100-foot-wide all-digital VHF AESA, but it also incorporated powerful higher-frequency radars that can track small targets once the VHF radar has detected them. More recently, however, it has emerged that the U.S. Navy is worried because new Chinese warships carry the Type 517M VHF search radar, which its maker says is an AESA.None of this is to say that stealth is dead, but it is not reasonable to expect that the cat-and-mouse game of detection and evasion in air combat has stopped, or that it ever will. EA and stealth still do not coexist very comfortably on the same platform, but offboard EA and stealth are synergistic: the smaller the target, the less jamming power is needed to mask it.

But the threat’s demonstrated agility drives home the lesson that there is no one winning move in the radar game. Excessive reliance on a single-point design is not a good idea, and using fictitious secrecy to quash the debate is an even worse one.

F35 Ejector seat trials

F-35 arrives at Glendale's Luke Air Force Base

Luke AFB is projected to become the USAF’s primary F-35 pilot-training base and the largest F-35 base worldwide. U.S. pilots and foreign pilots alike will train there before deploying to combat units worldwide.

Luke officials expect additional F-35s to arrive a couple of times a month until the base has six squadrons of 24 planes each. They anticipate receiving about 15 more F-35s during the rest of 2014.

US Navy to order 33 fewer F-35s than planned in next 5 yrs

The U.S. Navy is set to order 33 fewer Lockheed Martin Corp F-35 fighter jets than originally planned over the five years starting in fiscal 2015 due to budgetary pressures, a defense official said.

In a move that will sharply slow work on the F-35 model built to land on aircraft carriers, the Navy will ask Congress to fund 36 F-35Cs instead of 69, said the official, who could not speak publicly ahead of Tuesday's release of the 2015 budget request.The Air Force is also deferring orders for four conventional landing F-35 A-models in fiscal 2015, but is expected to resume its planned orders for the jet in 2016 and beyond, said a second source familiar with the plans. It plans to order 238 in total.

The Marine Corps, which expects to start using its F-35 B-model jets in combat from mid-2015, is sticking to its projected orders of 69 jets for the period, the sources said.That adds up to 343 F-35s to be funded by the U.S. military through fiscal 2019, excluding three Marine Corps jets that could be added to the Pentagon's war funding request, which will be submitted in April or May.
