Aces High: USA Developing New 3DELRR Long-Range Ground Radar

AN/TPS-75

The US Air Force’s AN/TPS-75 radar has been in service since 1968. Threats have evolved, and they want to replace it as its main long-range, ground-based radar for detecting, identifying and tracking aircraft and missiles, then reporting them through the Ground Theater Air Control System. The US Marines are considering a similar move, to replace their own AN/TPS-59s. Hence the USA’s Three-Dimensional Expeditionary Long-Range Radar (3DELRR, pron. “Three Dealer”).

3DELRR is intended to provide long-range surveillance, control of aircraft, and theater ballistic missile detection. It will correct AN/TPS-75 shortfalls by being easier to maintain, thanks to AESA technology, and by detecting and reporting highly maneuverable and/or stealthy targets. Its improved resolution may even allow it to classify and determine the type of non-cooperative aircraft that cannot or do not identify themselves – a trait that allows faster engagement of hostile planes, and reduces the odds of friendly fire incidents. As long as the program itself can avoid friendly fire from the USA’s budget wars.

Russia’s Yak-130 Trainer & Light Attack Jets

Yak-130

Russia’s air force (VVS) aged badly in the wake of the Cold War, and the lack of replacements soon made itself felt in all areas. One of those areas involved advanced jet trainers, which form the last rung on the ladder before assignment to fighters. Russia’s Czech-made L-29 and L-39 trainers were left with questionable access to spare parts, and a competition that began in the 1990s finally saw Yakolev’s Yak-130 collaboration with Italy’s Finmeccanica beat the MiG-AT in 2002. Unfortunately, Russian budget realities allowed orders for just a dozen early production Yak-130s, even as the VVF’s L-39 fleet dwindled drastically.

The Yak-130′s multi-mission capabilities in training, air policing, and counterinsurgency make it an attractive option for some customers beyond Russia. Initial export successes helped keep Yak-130 production going, via confirmed orders from Algeria (16), and unclear relationships with Kazakhstan, Libya, and Vietnam. In December 2011, however, Russia finally placed a significant order that got production started in earnest. Russia continues to promote the aircraft abroad, and now that the plane’s future is secure, interest and orders are picking up.

Russia’s SU-35 Super-Flanker: Mystery Fighter No More

SU-35 flight test, 2009

The Russian SU-35 was something of a mystery for many years. Pictures from Russian firms showed different fighter jets carrying that label, even as the aircraft remained a prospective design and research project, rather an active program of record.

Revelations after 2007 began to provide answers. This article explains the sources of the widespread confusion regarding the SU-35′s layout and key characteristics, reviews what is now known about the platform, and tracks its development. Those developments are likely to have broad consequences. The aircraft now has a home customer in the Russian Air Force, and the SU-35 is being positioned to replace most SU-30MK variants as Russia’s fighter export of choice within the coming decade. Will its succession bid succeed?

Unmanned Hellos: The USMC’s Unmanned Cargo Helicopters

K-MAX: where’s Waldo?

Unmanned drones for aerial surveillance are routine now. UAV systems that can use weapons are also routine. What isn’t routine yet is cargo resupply, but the Marines were asking for it in Afghanistan. That’s no easy task, since the country’s geography really hates helicopters. Can a helicopter UAV handle Afghanistan’s high altitude terrain, and show that it has what it takes to get its cargo exactly where it needs to go? The Marines thought so. Adm. Bill Shannon, NAVAIR Program Executive Officer for Unmanned Aviation and Strike Weapons, says:

“We are trying to get this much needed capability to the warfighter as quickly as possible… By evaluating two different systems, we have the ability to accelerate development of technology and use it immediately to support the warfighter while maintaining competition.”

From its inception, the competition has been a battle between Lockheed Martin’s larger-capacity but shorter-endurance K-MAX, and Boeing’s quiet, ultra long-endurance A160T Hummingbird. K-MAX won, and the Marines’ cargo UAV experiment began. It’s still going…

F-35 Lightning: The Joint Strike Fighter Program, 2012 – 2013

F-35B: off probation

The $382 billion F-35 Joint Strike fighter program may well be the largest single global defense program in history. This major multinational program is intended to produce an “affordably stealthy” multi-role fighter that will have 3 variants: the F-35A conventional version for the US Air Force et. al.; the F-35B Short Take-Off, Vertical Landing for the US Marines, British Royal Navy, et. al.; and the F-35C conventional carrier-launched version for the US Navy. The aircraft is named after Lockheed’s famous WW2 P-38 Lightning, and the Mach 2, stacked-engine English Electric (now BAE) Lightning jet. Lightning II system development partners included The USA & Britain (Tier 1), Italy and the Netherlands (Tier 2), and Australia, Canada, Denmark, Norway and Turkey (Tier 3), with Singapore and Israel as “Security Cooperation Partners,” and Japan as the 1st export customer.

The big question for Lockheed Martin is whether, and when, many of these partner countries will begin placing purchase orders. This updated article has expanded to feature more detail regarding the F-35 program, including contracts, sub-contracts, and notable events and reports during 2012-2013.

Japan’s Next Fighters, From F-X Competition to F-35 Buys

F-35A

In December 2011, Japan picked Lockheed Martin’s new F-35A stealth fighter as its next fighter aircraft, to replace its aging F-4 “Kai” Phantom fleet. The F-35 was actually their 2nd choice.

Back in February 2006, Inside The Air Force (ITAF) reported that momentum was building within the USAF to sell the ultra-advanced F-22A Raptor abroad to trusted US allies, as a way of increasing numbers and production. Japan clearly wanted them, and the Raptor was a topic of diplomatic discussions in several venues, including a 2007 summit meeting. In the end, however, US politics denied export permission for downgraded export variants of the F-22, and its production line was terminated. That left Japan looking at other foreign “F-X” fighter options in the short term, while they considered a domestic stealth fighter design as their long-term project.

In the ensuing F-X competition, the F-35 Lightning II beat BAE’s Eurofighter Typhoon, as well as an upgraded F/A-18E Super Hornet from Boeing. Now Lockheed Martin has to deliver, and so will its Japanese partners. Will the F-35A’s price and program delays create problems in Japan? This article looks at the JASDF’s current force, its future options, and ongoing F-X developments.

The USA’s DDG-1000 Zumwalt Class Program: Dead Aim, Or Dead End?

67% of the fleet

The prime missions of the new DDG-1000 Zumwalt Class destroyer are to provide naval gunfire support, and next-generation air defense, in near-shore areas where other large ships hesitate to tread. There has even been talk of using it as an anchor for action groups of stealthy Littoral Combat Ships and submarines, owing to its design for very low radar, infrared, and acoustic signatures. The estimated 14,500t (battlecruiser size) Zumwalt Class will be fully multi-role, however, with undersea warfare, anti-ship, and long-range attack roles.

True, or False?

That makes the DDG-1000 suitable for another role – as a “hidden ace card,” using its overall stealth to create uncertainty for enemy forces. At over $3 billion per ship for construction alone, however, the program faced significant obstacles if it wanted to avoid fulfilling former Secretary of the Navy Donald Winter’s fears for the fleet. From the outset, DID has noted that the Zumwalt Class might face the same fate as the ultra-sophisticated, ultra-expensive SSN-21 Seawolf Class submarines. That appears to have come true, with news of the program’s truncation to just 3 ships. Meanwhile, production continues. DID’s FOCUS Article for the DDG-1000 program covers the new ships’ capabilities and technologies, key controversies, associated contracts and costs, and related background resources.

The New Chinooks: Boeing’s Modern H-47 Heavy-Lift Helicopters

CH-47Fs take off

DII FOCUS articles offer in-depth, updated looks at significant military programs of record; this FOCUS Article covers the CH-47F/MH-47G Chinook helicopter programs, in the USA and abroad. These helicopters’ distinctive “flying banana” twin-rotor design stems from the brilliant work of aviation pioneer Frank Piasecki. It gives Chinooks the ability to adjust their positioning very precisely, while carrying a large airframe whose load capacity has made it the world’s most popular heavy-lift helicopter. The USA expects to be operating Chinooks in their heavy-lift role past 2030.

The CH-47F looks similar to earlier models, but offers a wide range of improvements in almost every aspect of design and performance. While the related HH-47′s $10-15 billion CSAR-X program win has been nullified by the program’s termination, delivery orders continue for CH-47Fs and for MH-47G Special Forces configuration helicopters. International orders or formal requests have also come in from Australia, Britain, Canada, Italy, the Netherlands, Turkey, and the UAE, with India and other countries expected to follow.

EMALS: Electro-Magnetic Launch for Carriers

EMALS Components

As the US Navy continues to build its new CVN-21 Gerald R. Ford Class carriers, few technologies are as important to their success as the next-generation EMALS (Electro-MAgnetic Launch System) catapult. The question is whether that technology will be ready in time, in order to avoid either costly delays to the program – or an even more costly redesign of the first ship of class.

Current steam catapult technology is very entertaining when it launches cars more than 100 feet off of a ship, or gives naval fighters the extra boost they need to achieve flight speed within a launch footprint of a few hundred feet. It’s also stressful for the aircraft involved, very maintenance intensive, and not really compatible with modern gas turbine propulsion systems. At present, however, steam is the only option for launching supersonic jet fighters from carrier decks. EMALS aims to leap beyond steam’s limitations, delivering significant efficiency savings, a more survivable system, and improved effectiveness. This free-to-view spotlight article covers the technology, the program, and its progress to date.

Despite Problems, SBIRS-High Moves Ahead

SBIRS-High

Space Based Infrared System (SBIRS)-High satellite program is a key component of the USA’s future missile alert system, designed to give maximum warning and monitoring of ballistic missile launches anywhere in the world. The new satellites will replace the existing Defense Support Program (DSP) fleet. Their infrared sensors have 3x the sensitivity of DSP and 2x the revisit rate, while providing better persistent coverage.

Unfortunately, the program has been beset by massive cost overruns on the order of 400%, technical challenges that continue to present problems, and uncertainties about performance. Despite these problems, the U.S. Air Force is proceeding with the program, and has terminated potential alternatives and supplements.
