First F-35 Sale To UAE Could Still Be Years Away

 Aviation Week & Space Technology

During the same week as the Dubai Airshow in November 2009, Lockheed Martin celebrated the first flight of the AF-1 test aircraft for the F-35 development program, and a top air force official in the United Arab Emirates (UAE)—Brig. Gen. Ibrahim Naser Alalawi—publicly declared his “hope” that his country would procure a fifth-generation fighter “within a couple years.” A decade later, Lockheed has delivered more than 435 F-35s to eight countries, but none so far to the UAE. 

With the 2019 edition of the biannual air show ready to run from Nov. 17-21, the UAE’s search for a new stealth fighter may be set to take nearly another decade. In the last two years, the UAE has commissioned a billion-dollar upgrade program for the air force’s F-16 Block 60s and launched a service-life extension program for its Mirage 2000s. The combination gives the UAE the flexibility to defer one of the world’s largest fleet replacement programs for fighters by several years. 
“It certainly looks like the UAE is trying to skip a generation and coast on their F-16 Block 60 and Mirage 2000 force until they can get F-35s, which will likely be around 2026 or 2027,” says Richard Aboulafia, vice president of analysis for the Teal Group consultancy. That timeline assumes orders by the UAE around 2024, followed by deliveries to a U.S. training base in 2026 and transfer to the UAE around a year later, Aboulafia says. 

It was only two years ago that the UAE’s potential F-35 order appeared more imminent. During the first year of U.S. President Donald Trump’s administration, officials succeeded in reopening stalled negotiations with the Gulf Cooperation Council on several arms sales. “The Obama administration would not talk about the F-35” to countries in the Middle East, says Derek Bisaccio, a regional market analyst for Forecast International. “That seemed to change when Trump took office.” U.S. defense officials openly discussed the “ongoing,” early talks with the UAE about a potential F-35 deal during the last Dubai Airshow in 2017. 
The timing of the new sales discussions also followed a pattern of U.S. policy. The first F-35I ordered by Israel arrived at Nevatim AB in December 2016. The U.S. government generally offers Israel at least a five-year head start on new fighter technology, then allows other governments in the regions to import the aircraft, Aboulafia says. 
The F-35 may not be the only fighter on the UAE’s long-term shopping list. Alalawi displayed a picture of the F-35 as he expressed hope in a fifth-generation fighter acquisition in 2009, but the UAE is not exclusively tied to the American fighter. In 2017, the UAE government signed a memorandum of understanding with the Russian Aircraft Corp. to collaborate on the design of a lightweight, next-generation fighter. Neither side has publicly moved the relationship forward over the last two years.
“There’s been precious few details on what the concept of the aircraft would be,” Bisaccio says. “This could well prove in time for the UAE a bargaining chip in negotiations with the United States.”
The UAE has been careful to avoid reliance on a single government for weapons. The current fighter fleet is split between the U.S.-made F-16s and French-built Mirage 2000s. That policy could continue even if the UAE signs a deal in the long term for F-35s.

“There’s still a chance the UAE Air Force is going to give a little bit to everybody,” says Michel Merluzeau, director of Aerospace Market Analysis for AirInsight. “If they acquire an F-35, I think they’d go with a micro-fleet. Maybe a wing: 30-40 aircraft. It would be a mistake to think they’d buy an equivalent number of fighters as they did with the F-16.”
The most logical alternative to the F-35 for the UAE could be the RafaleDassault’s successor to the UAE Mirage 2000 fleet. Block upgrades, such as the F4 and F5, will introduce teaming capabilities with unmanned combat air vehicles, along with new weapons and sensors. 
For the moment, the UAE has time to wait and consider its options. The service-life extension for the Mirage 2000 fleet provides the UAE with at least a decade to deliver a replacement. 
“When you look at the [Mirage 2000s], these are near [the] Rafale in terms of avionics and weapon systems,” Merluzeau says. “They have a good 10 years left.”

KAI Begins Building KF-X Prototype For 2022 Flight

 and  Aviation Week & Space Technology

Korea Aerospace Industries (KAI) has begun building the first prototype for the KF-X fighter program, following completion of the critical design review in September. Development is running on schedule, a source close to the program says.

Meanwhile, South Korea’s defense technology organization and Hanwha have flight-tested a technology-demonstration fighter radar in cooperation with Elta Systems, while proceeding in parallel with full-scale development of the sensor for the KF-X.
Rollout of the first KF-X prototype is due in June 2021 and its first flight in May 2022, the source says, giving more precise timings than those that have been published. 
Production of the first aircraft, a single-seater, is beginning with the forward fuselage. There will be four single-seat and two twin-seat prototypes. These aircraft will be built to the Block 1 standard, cleared for air-to-air missions only. The Block 2 will introduce air-to-surface capability. Although the KF-X is designed for eventual development of a stealthy version, the government has given no indication of when that may happen.
The first flight-test aircraft is following the strength-test airframe into manufacturing. KAI began building that static test structure in March.
South Korea requires 120 KF-Xs to replace Lockheed Martin F-16s. Indonesia is a junior partner in the program, with a reported requirement for 50 aircraft. 

The twin-engine fighter is powered by the General Electric F414-GE-400K turbofan generating 22,000 lb. thrust. Maximum speed will be 2,200 kph (1,370 mph), according to KAI, revealing the figure for the first time since exploratory development. Payload will be 7.7 metric tons (17,000 lb.) and ferry range 2,900 km (1,800 mi.), it says.
The air force is due in 2024 to review test results and, if satisfied, advise the defense ministry to issue a production contract, says the source. Manufacturing of delivery aircraft will then go ahead while flight testing proceeds to a targeted completion in June 2026, winding up Block 1 development about 10.5 years after program launch. Then deliveries are supposed to begin in late 2026.
KAI displayed a full-scale mockup at the Seoul Aerospace and Defense Exhibition, held on Oct. 15-19. The mockup shows no changes from the preliminary design that the air force approved in July 2018.
The KF-X is initially being designed to use the MBDA Meteor long-range and Diehl IRIS-T short-range air-to-air missiles. Washington routinely withholds permission for integration of U.S. air-to-air missiles in the first few years of a foreign fighter program, so Seoul will seek approval for the work after the first flight, says a South Korean government source who is close to the program. The Raytheon AIM-120 medium-range and AIM-9 short-range weapons are presumably the desired weapons.
More than 1,000 engineers are working at KAI on the KF-X. One issue debated before program launch in late 2015 was whether KAI could find it had insufficient engineering resources to develop the aircraft, which has an empty weight of 12 metric tons. The first source says the problem has not arisen.
The radar demonstrator, mounted in Elta’s Boeing 737 testbed, was flown 10 times in Israel and six times in South Korea, says a researcher from the technology organization, the Agency for Defense Development (ADD).
The ADD is leading development of the radar. Officially, Hanwha is contracted for manufacturing, but officials close to this work say the company is also helping in development.
The radar program was committed to full-scale development before technology demonstration. The intended production radar passed its critical design review in May 2019. Development is due for completion in 2026, so it will be ready just as KF-X deliveries are due to begin.
The radar has an active, electronically scanned array (AESA). In 2014, before KF-X full-scale development began, the government’s Electronics and Telecommunications Research Institute said it would use gallium-nitride semiconductors. It will have about 1,000 transmitter-receiver modules, local media say.
Building and testing the technology demonstrator is the first phase, which includes software for air targets. The second phase will produce software for ground and sea targets, Lee Bumseok, the head of the ADD division handling the project, said at a seminar ahead of the exhibition. This phase is due to be completed in October 2021. A prototype radar is due to be fitted in a KF-X prototype in 2023. 
South Korea has not previously developed a fighter radar. It has built indigenous naval and ground radars, including some with AESAs, but its experience looked so limited that foreign companies expected one of them would provide the technological foundation for the program.
Instead, the ADD was authorized to create a fully South Korean radar. Elta is supposed to play a relatively minor supporting role, but it is clearly positioned to step up its involvement should the program run into trouble.

South Korea joins Asia’s Carrier Race

Dokdo-class vessels
The Republic of Korea (ROK) recently announced that it plans to launch by 2030 a large-deck amphibious-warfare ship that could handle Short Take Off and Vertical Landing (STOVL) aircraft.
With a displacement of 30,000 tons, the new Landing Platform Helicopter (LPH) is over twice the size of its predecessors, the 14,500-ton Dokdo-class vessels, and is expected to have significantly more capabilities. For instance, its aviation complement could number 20 STOVL jets (likely to be the Lockheed Martin F-35B Lightning) on top of other air assets, and this is a step-change from the Dokdos with their dozen helicopters. This development is part of an ambitious five-year naval build-up unveiled in mid-August that includes ballistic missile defence-capable Arleigh Burke type Aegis destroyers and submarines armed for land attack. LPX-II, the official name for the ROK’s new capital ship, marks the first time the republic is pursuing a true aircraft carrier-type platform. What then are the main drivers behind this keystone acquisition?
South Korea’s Ministry of National Defence stated in no uncertain terms that the naval build-up has North Korea in mind. Indeed, its northern neighbour has been an existential threat for much of its history. Should a second Korean War break out, ROK airfields could be prime targets for the much-feared artillery, tactical ballistic missiles, and special operations forces of the Korea’s People Army (KPA). Having a carrier force would mitigate this threat. Should its land bases be knocked out, South Korea could turn to sea-based airpower for one of its ‘second-strike’ options. it could be argued that the relatively small air wing of an LPX-II militates against it shaping the battlespace to any significant degree. However, this line of reasoning ignores the fact that the flat-top could bring about disproportionate strategic effects. A carrier force could use its mobility and speed to complicate the enemy’s calculus, and trying to locate one (or two) of them roaming off the North Korean coasts in the Japan and Yellow Seas is essentially trying to find a needle in the haystack. Matters are not helped by the KPA’s anaemic naval and air-defence capabilities.
Another driver behind the LPX-II acquisition would be the increasing uncertainty clouding the north-east Asian geo-strategic environment. China is becoming increasingly assertive in its environs and the People’s Liberation Army-Navy (PLAN) is growing from strength to strength. In addition, South Korea’s ties with Japan are at its lowest ebb in recent times. In August, the ROK ended a military intelligence-sharing deal with Japan in a tit-for-tat move against trade sanctions imposed by Tokyo a month earlier. Soon after the termination of the deal, the South Korean military launched an exercise aimed at demonstrating control over the Dokdos that Japan also claims. Even though these islets are within range of South Korean land-based aircraft, the highly maritime nature of this spat means that there would be a premium placed on sea-based airpower during any crisis. For instance, the latter offers various tactical advantages over its shore-based counterpart, such as longer loiter time in the area of operations. It also bears consideration that the LPX-II was revealed after Japan said its Izumo-class “helicopter destroyers” could be converted to carriers. And just over a week after the LPX-II’s unveiling, Tokyo officially announced that it will buy the F-35B from the United States. Are these developments too much of a coincidence perhaps?
All in all, continual inter-state tensions are probably the main factor driving South Korea’s aircraft carrier ambitions. Moreover, with the ROK gazing increasingly towards the ‘blue waters’ and concomitantly out-of-area operations, having a carrier would stand South Korea in good stead should it partake in a major humanitarian-assistance/disaster-relief mission given that the vessel could then be a key node in such an operation. In summery, the utility of a carrier-like platform invariably expands a nation’s military toolbox, and it makes for a good hedge against the uncertainties of the regional security environment. There is arguably a prestige element to the LPX-II acquisition as well. Flat-tops are the ‘Queen of the Waves’, and owning (and being able to operate) them invariably adds to a country’s standing amongst the league of nations. Indeed, possessing an aircraft carrier seems to be par the course for medium powers these days, with the likes of Australia, India and Japan already having or working towards such a capability. While South Korea’s current Dokdo-class vessels are certainly aviation-capable, they are too small in size and too limited in capability to be categorised even as ‘quasi-carriers’. The LPX-II, however, would change that state of affairs.


Reinventing the Small Wind Turbine

Many commercially available small wind turbines with plastic blades and steel towers are infamous for their low reliability, high embodied energy, and limited power output.
Building them out of wood can address these issues. Because of their aesthetic appeal, and thanks to the ability to produce them locally, small wooden wind turbines can also improve the public acceptance of wind power.
Furthermore, innovation in tower design facilitates the installation of small wind turbines, reducing the need for concrete foundations and heavy machinery.
