Argentina Mulls Formal Inspection of Chinese 'Space Station' Amid Growing Tensions

 Argentina's stance on its relationship with China is increasingly evident, with plans underway for a formal inspection of a Chinese "space station" situated on Argentine soil. The station, established in 2014 under an agreement with the previous administration, has raised concerns and triggered suspicions within the US government.

The Argentine government is considering a thorough inspection to evaluate potential irregularities associated with the base and ensure compliance with contractual obligations. This move coincides with Argentina's recent procurement of surplus F-16 fighter jets from Denmark, signaling a shift towards alignment with Western powers under President Javier Milei's leadership.

While China claims the station is for peaceful space exploration, concerns persist about its military implications and the lack of Argentine oversight. US officials have expressed skepticism, highlighting the need for transparency regarding China's activities at the base.

Despite past defenses of the station by Argentine administrations, questions remain about its operational control and the extent of Chinese military involvement. While some experts suggest US concerns may be overstated, the inspection reflects Argentina's efforts to assert control over its territory amid geopolitical tensions.

Thailand's Fighter Jet Decision: Boeing F-16, SAAB Gripen, or Korean FA-50?

 Thailand is considering acquiring a new fourth-generation fighter aircraft, with options including the Boeing F-16 and SAAB Gripen. Now, the South Korean contractor Korea Aerospace Industries (KAI) has thrown its hat into the ring, proposing its FA-50 light fighter aircraft to the Royal Thai Air Force (RTAF).

KAI's proposal comes in response to an informal request for proposals (RFP) from the RTAF, aiming to replace aging Lockheed Martin F-16A/Bs. While the FA-50 offers advanced capabilities at a lower cost and with timely delivery, the RTAF had initially shown interest in fifth-generation F-35 Lightning II aircraft.

The FA-50, an export success for KAI, boasts features such as Tactical Data Link and Precision Guided Munitions. It has been actively deployed by the Republic of Korea Air Force (ROKAF) since 2013 and has garnered significant orders from countries like Poland and Malaysia.

Despite initial interest in the F-35, the RTAF aims to bolster its air power with potent fighter jets. The competition now includes the F-16 Block 70/72 Viper and SAAB Gripen-E, both offering advanced capabilities in their generation.

With the entry of the FA-50 into the contest, the RTAF faces a three-way decision, potentially reshaping its evaluation process and strategic considerations.

Taiwan's Upgraded F-16 Vipers Suffer Earthquake Damage: Strategic Implications Amid China's Military Buildup

 Taiwan experienced a powerful 7.2-magnitude earthquake on April 3, causing significant damage and prompting the Republic of China Air Force (ROCAF) to evaluate the impact on its military assets, particularly its fleet of F-16 fighters.

The earthquake, centered off the coast of Hualien, resulted in casualties and widespread destruction, with reports indicating damage to upgraded F-16 fighters stationed at Hualien Air Base, near the epicenter. While official sources confirmed minor damage to six F-16 jets, alternative reports suggested a higher number of affected aircraft.

Damage to the F-16s was primarily superficial, limited to minor scratches and components dislodged due to the tremors. Immediate repair efforts were initiated to restore operational readiness, although reports hinted at cracks in infrastructure at Hualien Air Base, underscoring its strategic importance in Taiwan's defense posture against potential Chinese threats.

Taiwan's investment in upgrading its F-16 fleet to the advanced Block 70/72 Viper configuration reflects its commitment to modernizing its air defense capabilities. Equipped with state-of-the-art avionics, including the Northrop Grumman AN/APG-83 Scalable Agile Beam Radar (SABR), these aircraft offer increased detection and engagement ranges, enhancing Taiwan's ability to counter various threats, including cruise missiles.

Moreover, the F-16V's versatility in armament, featuring advanced missiles like the AGM-84 Harpoon and AGM-88 High-Speed Anti-Radiation (HARM), further strengthens Taiwan's defensive capabilities. However, delays in the procurement of new F-16 Block 70/72 Vipers pose challenges amid escalating tensions with China and underscore the need for Taiwan to bolster its air defense infrastructure for strategic resilience.

Dutch F-35s Replace F-16s in NATO’s Quick Reaction Alert: Nuclear-Capable Interceptors on Standby

 On March 29, Dutch F-35s assumed the Quick Reaction Alert (QRA) duties previously held by F-16s, signaling a shift towards retiring the latter. Tasked with guarding the airspace over Belgium, the Netherlands, and Luxembourg, these F-35s from the Royal Netherlands Air Force (RNLAF) will rotate until May 9, with Belgian Air Force taking over thereafter.

NATO's QRA involves fighter aircraft scrambling to investigate potential airspace violations, requiring coordinated responses between reporting centers and pilots. The F-35's advanced capabilities, including powerful radar, stealth, and sensor fusion, make it a formidable interceptor, capable of identifying and engaging enemy aircraft before detection.

Operating from Leeuwarden and Volkel Air Base, the RNLAF's F-35As replace the aging F-16s, part of the phased transition towards a fleet of 52 F-35As. These aircraft, equipped with modern technology, ensure continuous readiness for rapid interception, particularly crucial amidst heightened tensions with Russia.

Despite past issues, including crashes and cost overruns, the F-35's cutting-edge features are acknowledged even by Russia-leaning experts. Furthermore, recent certification allows the F-35A to carry the B61-12 nuclear bomb, making it a dual-capable aircraft. However, this capability is currently limited to a new variant of the bomb, gradually replacing older versions.

Notably, the Dutch and Belgian air bases hosting these aircraft are also among the six NATO bases storing US-owned nuclear weapons, highlighting the strategic significance of these deployments. While details remain undisclosed, it's expected that all F-35As in the Dutch inventory will eventually be nuclear-capable, reflecting the need for operational redundancy.

Argentina Secures Deal to Purchase Surplus F-16 Jets from Denmark

 Argentina has finalized an agreement to acquire 24 surplus F-16 fighter jets from Denmark as part of the latter's transition to newer F-35 aircraft. The deal was sealed during a signing ceremony in Buenos Aires, where Argentine Defense Minister Luis Petri and his Danish counterpart Troels Lund Poulsen inked a letter of intent.

Denmark's decision to sell its F-16 jets to Argentina follows its donation of 19 such jets to Ukraine. The transaction, described as a "possible sale," has been conducted with close coordination with the American government, which has approved the transfer of these US-produced aircraft.

Sources within the Argentine military, speaking on condition of anonymity, revealed that Argentina will pay approximately $320 million for the acquisition. Financing for the deal will involve loans from banks and the United States. Additionally, the agreement encompasses not only the aircraft but also includes weapon systems and other equipment from US manufacturers, with Denmark providing simulators and spare parts.

The final contract is expected to be signed by the end of April in Copenhagen. The US Defense Security Cooperation Agency will oversee the transfer of weapon systems, including AIM-120 missiles, through the Foreign Military Sales program. Meanwhile, Denmark's Acquisition and Logistics Organisation will manage the transfer of surplus F-16s, while Argentina's military logistics directorate will supervise the procurement process.

Negotiations for this deal began under Argentina's previous government, exploring the possibility of procuring JF-17 fighter jets manufactured jointly by China and Pakistan. However, concerns about potential implications for US military relations led to the rejection of the JF-17 acquisition, paving the way for the purchase of F-16s from Denmark.

Putin's Warning: F-16s Vulnerable to Russian MiG-31s? Analysis & Threat Assessment

 Russian President Vladimir Putin cautioned that US-supplied F-16 Fighting Falcons to Ukraine could become targets if employed against Russian forces from third-party nations' airfields. Putin's statement follows NATO's announcement granting Ukraine authority to deploy F-16s to engage legitimate Russian military targets beyond its borders.

The F-16s, intended to modernize Ukraine's aging fleet and strengthen its air force capabilities, pose a strategic shift towards Western integration and reduced reliance on outdated Soviet-era aircraft.

However, Russia maintains a formidable aerial advantage, primarily through the deployment of MiG-31 fighter jets armed with the long-range R-37M missile. These missiles have proven effective against Ukrainian aircraft, including instances of downing MiG-29s and deterring foreign surveillance aircraft like the Norwegian P-8A Poseidon.

The MiG-31, a legacy aircraft from the Cold War era, boasts advanced digital avionics and a rear-seated weapon systems officer. Equipped with the Zaslon radar, capable of tracking multiple targets simultaneously, the MiG-31 remains a potent air dominance fighter despite its limited close combat capabilities.

Enhancements in the MiG-31BM variant include network-centric combat control, upgraded radar systems, and extended service life. With a focus on multi-role capability, the MiG-31BM can engage air, surface, and ground targets with improved efficiency.

Additionally, the introduction of hypersonic air-to-air missiles like the R-37M and Kinzhal further bolsters Russia's offensive capabilities, posing a significant challenge to Ukraine's air force.

In response, Ukraine's acquisition of surplus F-16s from NATO allies aims to augment its aerial capabilities. However, the F-16s equipped with AIM-120 air-to-air missiles face challenges against the MiG-31/R-37M combination, necessitating upgrades to narrow the capability gap.

Despite the disparity, F-16s could potentially push back MiG-31s, enabling deeper incursions into Russian airspace and enhancing operational effectiveness over occupied territories.

As tensions escalate, the evolving dynamics between Ukraine's F-16s and Russia's MiG-31s underscore the complex geopolitics and strategic considerations at play in the region's airspace.

China Unveils J-15D Electronic Warfare Aircraft: A Game-Changer in Naval Aviation?

 China has showcased its electronic warfare (EW) version of the carrier-based J-15 fighter, termed the J-15D, through Chinese state media. The aircraft, reminiscent of the US Navy's E/A-18G Growler, integrates EW capabilities into a fast-flying jet fighter, as depicted in footage aired by China Central Television (CCTV).

The J-15D features distinctive pods, akin to those seen on the J-16D. Notably, China drew inspiration from the US F-16 C/D Block 52/60 design for integrating EW systems into the J-10D, making the J-15D the third fighter-based EW platform in the Chinese arsenal. Originating as a Chinese iteration of the Russian Su-33, the J-15 serves as a carrier-based aircraft.

Speculation surrounds the carrier from which the J-15D might operate, considering China's fleet of carriers, including the Liaoning, the Shandong, and the forthcoming Fujian. While visual evidence primarily showcases the Liaoning and the Shandong deploying J-15s, the J-15's heavy build may necessitate a Catapult Assisted Take-Off and Barrier Arrested (CATOBAR) flight deck, such as that found on the Fujian, equipped with an Electromagnetic Launch System (EMALS).

The J-15D's potential role aligns with its heavier counterpart's, the J-15, which specializes in carrying substantial payloads of anti-ship missiles. In contrast, lighter platforms like the J-31/J-35 focus on combat air patrol (CAP) and air superiority tasks.

Considering China's naval aviation strategy, the emergence of the J-15D, alongside the development of the J-31/J-35 and the introduction of the Fujian carrier, signifies a comprehensive enhancement of carrier-based capabilities. The J-15D is poised to play a pivotal role, akin to the US Navy's Growler, in providing electronic support and jamming capabilities during naval operations.

Greece to Sell F-16s and Mirage-2000s: A Strategic Shift in Air Force Modernization

 

Greece, having previously announced its intention to train Ukrainian fighter pilots on F-16s, has now revealed plans to decommission and sell its outdated F-16 and Mirage 2000 fighter jets. Despite the training program, Greece won't be sending any of these aircraft to Ukraine.

The Greek Defense Minister, Nikos Dendias, disclosed the decision to overhaul the Hellenic Air Force, emphasizing the need to streamline its aircraft types due to maintenance costs. The plan involves retiring F-4s, selling Mirage 2000-5s and Block 30 F-16s, and upgrading remaining F-16s to Viper level, alongside acquiring F-35s and strengthening the fleet of Rafales.

While the modernization aims to enhance uniformity and interoperability, Greece has opted not to offer its older jets to Ukraine, unlike other NATO allies. The US has authorized an $8.6 billion sale of F-35s to Greece, and Greece has agreements with France to purchase Rafales, indicating a strategic shift in its air force capabilities.

The specific aircraft slated for disposal include the F-16s, including the last 34 single-seat F-16C and six two-seat F-16D Block 30 aircraft. Despite Ukraine's pleas for fighter jets, Greece hasn't committed to transferring any, unlike other NATO allies. Greece's aircraft could still be beneficial for Ukraine, although they lack commonality with European F-16 operators.

Greece could potentially aid Ukraine with military equipment like the S-300 air defense systems, as hinted at by US Secretary of State Antony Blinken. However, there's no mention of transferring Greek combat aircraft to Ukraine, despite ongoing requests from the Ukrainian side.

Oman seeks Bid for Euro-fighter

The government of Oman has requested that BAE Systems submit a formal bid for the supply of Typhoon fighter aircraft. The move clarifies the Middle East nation’s continuing commitment to the program following delays in completing negotiations.

A spokeswoman for the U.K.-based defense company said it expected to complete negotiations by the end of the year, with deliveries of the first aircraft taking place 36 months later.

The request for proposals involves a squadron’s worth of Tranche 3 standard aircraft — about 12 airframes — a support package and training for the Omani air force.

Last month, Oman ordered a second batch of 12 F-16 Block 50’s from Lockheed Martin in a $600 million deal

The Omanis formally stated their intention to purchase the Eurofighter Typhoon in early 2010, and company executives said at the time that the deal could be ready for signing within months.

In a statement, BAE said it welcomed the release of the request for proposals, adding that the news underpins its long-standing defense and security relationship with the sultanate as a major equipment supplier.

The most recent major equipment sale was signed in 2007 to deliver three corvettes to the Omani navy in a deal valued at 400 million pounds.

The warships remain undelivered for technical reasons.

The first of the Khareef-class vessels should have been handed over in 2010 but have been delayed following the discovery of technical problems during sea trials.

The spokeswoman denied that the signing of the fighter deal between the two sides is dependent on the agreement of a get-well package for three corvettes.

The spokeswoman said the first of the corvettes is now scheduled to be handed over at the end of the second quarter.

The Omanis’ commitment to Typhoon follows recent competition losses for the fighter in Japan and Switzerland.

A decision by India on whether to select the Eurofighter aircraft or its French rival, Dassault Rafale, is imminent.

Earlier this month, BAE announced that talks with the Middle East’s first Typhoon customer, Saudi Arabia, over amendments to a deal to supply 72 fighters, were dragging on and would likely affect its 2011 earnings.

The original deal called for the first 24 aircraft to be delivered from the BAE production line in the U.K., with subsequent assembly in Saudi Arabia.

BAE and the Saudis announced a change of plan last February over where the final 42 aircraft would be built but are still haggling over the details.

Typhoon is a four-nation program involving the Germany, Italy, Spain and the U.K. So far, it has exported the aircraft to Austria and Saudi Arabia

U.S. Navy Document Plans Carrier Air Wings’ Future

The U.S. Navy’s carrier air wings of tomorrow will look very different from today’s, according to a new document produced by the sea services.

By 2032, the Navy’s fleet of F/A-18E/F Super Hornet fighters and new EA-18G Growler electronic attack jets will have begun to be replaced by new types, a new document called Naval Aviation Vision 2012 says.

The Navy will consider manned, unmanned and optionally manned aircraft to replace the long serving Rhino, as the F/A-18E/F is known to carrier deck crews. The Super Hornet will begin to reach the end of its service life around 2025 and must be replaced. The document says a competitive fly-off will be held at some point in the future.

The Super Hornet-derived EA-18G will also start being replaced by a new aircraft, but the document offers no further details.

Additionally, a new Unmanned Carrier Launched Surveillance and Strike (UCLASS) is to be integrated onto the carrier deck around 2018 — possibly with four to six planes embarked. The aircraft could make use of technologies developed by the X-47B program. The Navy document calls for “balanced survivability” so that the unmanned strike plane will be effective in “specified tactical situations.”

The F-35C will serve alongside these prospective aircraft.

But the Navy isn’t going to stop with replacing just its fixed-wing assets, as the document calls for the wholesale replacement of its helicopter fleet.

The MH-60 helicopter fleet will be supplanted by a new rotary-wing aircraft. The Fire Scout unmanned helicopter will also be replaced as will the MH-53E Sea Dragon counter-mine and heavy lift helicopter. In the case of the MH-53E, a replacement aircraft needs to be operational by 2026, the document says.

The Marines will get a Cargo Resupply Unmanned Aerial System (CRUAS) by 2032, and the service’s entire fleet of tactical remotely operated drones will be replaced. The Navy will continue to fly the Broad Area Maritime Surveillance version of the Global Hawk unmanned plane in 2032.

The training aircraft fleet will look similar to today’s, the document says. The T-6 and T-45C will soldier on, as will the TH-57 training helicopter. But the T-44 and TC-12B multi-engine turboprop trainers will be replaced with a new aircraft. The Marines’ C-20 and Navy’s C-26D and UC-12 fleets will also be replaced. As well, a new plane will take the place of the C-2 Greyhound carrier onboard delivery plane starting in 2026.

Nor has the Navy forgotten about its fleet of F-5 and F-16 aggressor aircraft. A replacement aggressor aircraft is envisioned for 2025, according to the document.

JSF may miss acceleration Goals

The F-35 Lightning II’s transonic acceleration may not meet the requirements originally set forth for the program, a top Lockheed Martin official said.

“Based on the original spec, all three of the airplanes are challenged by that spec,” said Tom Burbage, Lockheed’s program manager for the F-35. “The cross-sectional area of the airplane with the internal weapons bays is quite a bit bigger than the airplanes we’re replacing.”

The sharp rise in wave drag at speeds between Mach 0.8 and Mach 1.2 is one of the most challenging areas for engineers to conquer. And the F-35’s relatively large cross-sectional area means, that as a simple matter of physics, the jet can’t quite match its predecessors.

“We’re dealing with the laws of physics. You have an airplane that’s a certain size, you have a wing that’s a certain size, you have an engine that’s a certain size, and that basically determines your acceleration characteristics,” Burbage said. “I think the biggest question is: are the acceleration characteristics of the airplane operationally suitable?”

A recent report by the Defense Department’s top tester, J. Michael Gilmore, says that the Navy’s F-35C model aircraft, which has larger wing and tail surfaces, is not meeting requirements for acceleration.

The report doesn’t say whether the F-35A and F-35B have hit similar snags.

Richard Aboulafia, an analyst with the Teal Group, Fairfax, Va., said that the revelation was not particularly surprising.

“It’s a strike fighter,” Aboulafia said. “It’s not an interceptor; it’s not an F-22.”

Aboulafia said it was unclear whether additional engine power could boost acceleration in the difficult transonic regime. So far, doubts about the aircraft’s aerodynamic performance haven’t diminished Lockheed’s sales prospects, he said.

The F-35 transonic acceleration specifications were written based on clean-configuration F-16 Fighting Falcon and F/A-18 Hornet fighter, Burbage said.

But unlike the Hornet or the F-16, the F-35 has the same configuration unloaded as it does loaded with weapons and fuel, Burbage said. When an F/A-18 or F-16 is encumbered with weapons, pylons and fuel tanks, those jets are robbed of much of their performance.

“What is different is that this airplane has accelerational characteristics with a combat load that no other airplane has, because we carry a combat load internally,” Burbage said, the F-22 Raptor notwithstanding.

Even fully loaded, the F-35’s performance doesn’t change from its unencumbered configuration, he said.

In the high subsonic range between Mach 0.6 to Mach 0.9 where the majority of air combat occurs, the F-35’s acceleration is better than almost anything flying.

Thus far, Lockheed has not had issues with the plane’s acceleration, Burbage said. There are top level Key Performance Parameters from which lower level detailed engineering specification are derived and Lockheed’s job is to meet as many of those specifications as possible within the laws of physics, he said. Discussions are underway about if those original specifications are relevant given the jet’s acceleration in a combat configuration, Burbage added.

Air Force Lt. Col. Eric Smith, director of operations at the 58th Fighter Squadron at Eglin Air Force Base, Fla., and F-35 test pilot, said that flying the aircraft is a thrilling experience.

“I can’t even explain the adrenaline rush you get when you light the afterburner on that thing,” Smith said. “The acceleration is much better than an F-16.”

But the F-35’s aerodynamic performance is not what makes the jet special, Smith said. The F-35 powerful sensors and data-links and how that information is fused into a single coherent and easy to use display are what will make the jet an effective warplane.

Burbage added that while the F-35 is designed as a supersonic fighter, it’s not optimized for the extremely high supersonic speeds that the Raptor was designed to operate at.

“This is not a supercruising airplane like the F-22,” Burbage said.

Future Dogfights

Turkey to Order F-35 Fighters from U.S.

ANKARA - Turkey will buy a first batch of two F-35A Joint Strike Fighters as a sign of its commitment to the troubled U.S.-led program, the government's defense procurement agency said Jan. 5.

THREE F-35A TEST aircraft fly in formation over Edwards Air Force Base, Calif. Turkey moved ahead with its first order of the jets, the country's defense procurement agency announced Jan. 5. (Lockheed Martin)

A statement said the government had authorized the order to meet the future needs of the Turkish air force for next-generation fighter planes.

Turkey has long planned to purchase about 100 jets to replace its F-4 and F-16 fleet, but the increasing costs have hampered the acquisitions.

The Joint Strike Fighter, manufactured by Lockheed Martin, is the Pentagon's most expensive weapons program ever.

Its cost has jumped to about $385 billion, and the price of each plane is now well over $100 million. U.S. officials said last month that it has encountered a spate of technical problems expected to delay production still further.

However, Japan said it had chosen the F-35 for its next-generation mainstay fighter, ordering 45 of the aircraft in a deal worth around $4.7 billion.

The Pentagon plans three versions of the plane: the standard F-35A that would replace the F-16 fighter, the F-35C designed to land on naval carriers to replace the F-18 and the F-35B vertical take-off model that would supplant the Harrier aircraft flown by U.S. Marines.

Mideast Weapon Sales Part of Long-Term Plan: U.S.

The final days of 2011 saw the Obama administration finalize two important weapon sales with countries in the Middle East: a $3.48 billion sale of a Lockheed Martin-made missile defense system to the United Arab Emirates, and a $29.4 billion sale of Boeing-made F-15 fighter jets to Saudi Arabia.

While the announcements come as tensions between the United States and Iran continue to rise over a dispute regarding access to the Strait of Hormuz, the deals themselves are not meant to address current events, State Department officials said.

The F-15 deal was finalized with Saudi Arabia on Dec. 24. However, the White House first notified Congress of that sale, which includes 84 new aircraft and the modernization of 70 existing aircraft as well as missiles, spare parts, training, maintenance and logistics, in October 2010.

During a Dec. 30 State Department news conference, Andrew Shapiro, assistant secretary of state for political-military affairs, told reporters that the deal was not directed toward Iran, adding that work on the sale precedes the latest news out of the region.

"We did not gin up a package based on current events in the region," he said.

Over the last several weeks, the United States and Iran have stepped up the economic and military pressure on each other, with the latest threat coming from Iran, which warned the United States not to return one of its aircraft carriers to the gulf.

On Jan. 3, the Pentagon dismissed Iran's warnings.

"The deployment of U.S. military assets in the Persian Gulf region will continue as it has for decades," Pentagon Press Secretary George Little said in a statement. "Our transits of the Strait of Hormuz continue to be in compliance with international law, which guarantees our vessels the right of transit passage."

Meanwhile, Undersecretary of State for Political Affairs Wendy Sherman is on a four-day trip to Saudi Arabia and the UAE.

"While in the gulf region, she will consult with senior Saudi and Emirati officials on a wide range of bilateral and regional issues," according to the State Department. Her trip "further illustrates the robust strategic relationship the United States shares with both Saudi Arabia and the United Arab Emirates."

While the latest sales to the Middle East are being placed in this geopolitical context, the late December announcements are not tied to the escalating tensions, but part of a longer-term security plan, said Danny Sebright, president of the U.S.-UAE Business Council and a counselor at the Cohen Group, Washington.

"The overall sales with regard to both countries are definitely the result of a long-term concern with Iranian intentions, a long-term concern with wanting to improve individual countries' defense capabilities," Sebright said. "But, is the announcement of these two deals specifically tied to Iran? I would say no to that. I would say it's much more about internal decision-making in both countries - some with regard to terms and conditions of the sale, some with regard to budgeting, and some with regard to the Arab Spring."

According to Sebright, the United States gave the formal Letter of Offer and Acceptance to Saudi Arabia last spring and the Saudi government has been holding on to it until it was ready to sign.

"The basic deal had all but been done over a year ago, but they waited for internal and external reasons," he said.

A State Department official said, "While we decline to get into the specifics on the negotiations, the timeline here is not particularly atypical. A sale of this magnitude and complexity required close, continual consultations with our Saudi and industry partners to sort out the details."

Congress was first notified of the plan to sell UAE the Terminal High Altitude Area Defense System (THAAD) in September 2008. After negotiating the details of the contract, the United States and UAE signed the THAAD deal on Dec. 25. Lockheed Martin is on contract for four THAAD batteries for the U.S. Army, but the UAE deal is the program's first foreign sale.

Lockheed Martin's portion of the $3.48 billion sale is $1.96 billion. The overall deal includes two THAAD batteries, 96 missiles, two AN/TPY-2 radars, and 30 years of spare parts, support, and training to the UAE, according to the Pentagon.

Since the 2008 congressional notification, UAE trimmed the buy.

At first it was expected the country would buy three THAAD fire units, 147 missiles, and four radar sets for an estimated value of $6.95 billion.

The United Arab Emirates has asked Lockheed not to publicly discuss the delivery schedule of the weapon system, said Dennis Cavin, vice president of corporate business development at Lockheed Martin.

"This sale is an important step in improving the region's security through a regional missile defense architecture, and follows a number of recent ballistic missile defense-related sales," Little said in a Dec. 30 statement.

Sales from earlier in the year include a $1.7 billion direct commercial sales contract to upgrade Saudi Arabia's Patriot missiles and the sale of 209 Patriot GEM-T missiles to Kuwait, valued at about $900 million.

Loren Thompson, a defense analyst at the Lexington Institute, also put the sale in the context of December's announcement that Iraq would buy Lockheed's F-16s and Oman's decision to double the size of its F-16 fleet.

"When combined with the modernization of the Saudi Air Force and the extensive F-16 inventory of the United Arab Emirates, it is clear Arab gulf states will be positioned to greatly outmatch the antiquated tactical aircraft fleet of Iran," he wrote in a blog for Forbes.

According to Lockheed Martin, demand for missile defense capabilities continues to climb around the world.

"With regional threats in the Middle East and the uncertainties of what's going on in North Korea, demand for a very capable missile defense system has never been stronger," Cavin said. "The U.S. government is in discussion with a number of countries who have expressed interest in the THAAD, but we'd prefer that the Missile Defense Agency address any specifics with regard to which countries have contacted them."

The Missile Defense Agency declined to provide further details.

In announcing the Saudi deal, the State Department emphasized it would improve interoperability between the Saudi and American air forces.

In addition to greater cooperation with the United States, the sales also bolster internal cooperation among the Gulf Cooperation Council countries, which include Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the UAE, Sebright said.

The gulf countries have taken more steps to improve internal coordination and work toward multilateral defense policies in the last year than they have over the last 25, he said.
