Aging Aircraft: USAF F-15 Fleet Sees Renewed Interest

“Array of Aging American Aircraft Attracting Attention” discusses the issues that accompany an air force whose fighters have an average age of over 23.5 years – vs. an average of 8.5 years in 1967. One of the most obvious consequences is the potential for fleet groundings due to unforseen structural issues caused by time and fatigue. That very fear is responsible for the #1 priority placed on bringing new KC-X aerial tankers into the fleet to complement the USA’s 1960s-era KC-135 Stratotankers.

It can also affect the fighter fleet more directly.

Following the crash of a Missouri Air National Guard F-15C aircraft Nov 2/07 (see crash simulation), the US Air Force suspended non-mission critical F-15 flight operations on Nov 3/07. While the cause of that accident is still under investigation, preliminary findings indicate that a structural failure during flight may have been responsible. In response, Japan suspended its own F-15 flights, which left them in a bit of a bind – even as Israel’s F-15s joined them on the tarmac. As the effects continue to spread and the USAF and others continue to comment on this situation, DID continues to expand its coverage of this bellwether event. A conditional restoration of the American F-15A-D fleet to flight status was soon overturned by the re-grounding of that fleet as a result of the report’s conclusions – a status that remains only been partially lifted. Meanwhile, the accident report has been released (compete with video dramatization) and the status of the remaining aircraft will have significant implications for the USAF’s future F-15 fleet size. Not to mention its other procurement programs.

Then, too, this is America. Now there’s a lawsuit.

Raytheon’s APG-79 AESA Radars

The AN/APG-79 Active Electronically Scanned Array (AESA) radar began life as a replacement. Initial F/A-18 E/F Super Hornet production batches installed Raytheon’s all-weather, multimode AN/APG-73, but the APG-79 has intrinsic technical features that offered revolutionary increases in capability, reliability, image resolution, and range.

Unlike the APG-73 that equipped the first Super Hornets, the APG-79’s AESA array is composed of numerous solid-state transmit and receive modules that are fixed in place, eliminating a common cause of breakdowns. To move their beams, they rely on electronic changes in each module’s transmissions, creating useful interference patterns in order to aim, focus and shape their output. Other system components include an advanced receiver/exciter, ruggedized commercial-off-the-shelf (COTS) processor, and power supplies. With its open systems architecture and compact COTS parts, it changes what both aircrews and maintenance staff can do with a fighter radar – and does so in a smaller, lighter package.

Super Hornet Fighter Family MYP-III: 2010-2018 Contracts

The US Navy flies the F/A-18 E/F Super Hornet fighters, and has begun operating the EA-18G Growler electronic warfare & strike aircraft. Many of these buys have been managed out of common multi-year procurement (MYP) contracts, which aim to reduce overall costs by offering longer-term production commitments, so contractors can negotiate better deals with their suppliers.

The MYP-II contract ran from 2005-2009, and was not renewed because the Pentagon intended to focus on the F-35 fighter program. When it became clear that the F-35 program was going to be late, and had serious program and budgetary issues, pressure built to abandon year-by-year contracting, and negotiate another multi-year deal for the current Super Hornet family. That deal is now final. This entry covers the program as a whole, with a focus on 2010-2015 Super Hornet family purchases. It has been updated to include all announced contracts and events connected with MYP-III, including engines and other separate “government-furnished equipment” that figures prominently in the final price.

DDG Type 45: Britain’s Shrinking Air Defense Fleet

The 5,200t Type 42 Sheffield Class destroyers were designed in the late 1960s to provide fleet area air-defense for Britain’s Royal Navy, after the proposed Type 82 air defense cruisers were canceled by the Labour Government in 1966. Britain built 14 of the Type 42s, but these old ships are reaching the limits of their operational lives and effectiveness.

To replace them, the Royal Navy planned to induct 12 Type 45 Daring Class destroyers. The Daring class would be built to deal with a new age of threats. Saturation attacks with supersonic ship-killing missiles, that fly from the ship’s radar horizon to ship impact in under 45 seconds. The reality of future threats from ballistic missiles, and WMD proliferation. Plus a proliferation of possible threats involving smaller, hard to detect enemies like UAVs. Overall, the Type 45s promise to be one of the world’s most capable air defense ships – but design choices have left the cost-to-value ratio uncertain, and limited the Type 45s in other key roles. A reduced 6-ship program moved forward.

KF-X Fighter: Korea’s Future Homegrown Jet

South Korea has been thinking seriously about designing its own fighter jet since 2008. The ROK defense sector has made impressive progress, and has become a notable exporter of aerospace, land, and naval equipment. The idea of a plane that helps advance their aerospace industry, while making it easy to add new Korean-designed weapons, is very appealing. On the flip side, a new jet fighter is a massive endeavor at the best of times, and wildly unrealistic technical expectations didn’t help the project. KF-X has progressed in fits and starts, and became a multinational program when Indonesia joined in June 2010. As of March 2013, however, South Korea has decided to put the KF-X program on hold for 18 months, while the government and Parliament decide whether it’s worth continuing.

Indonesia has reportedly contributed IDR 1.6 trillion since they joined in July 2010 – but that’s just $165 million of the DAPA’s estimated WON 6 billion (about $5.5 billion) development cost, and there’s good reason to believe that even this development budget is too low. This article discusses the KFX/IFX fighter’s proposed designs and features, and chronicles the project’s progress and setbacks since 2008…

Airfields Afloat: The USA’s New Gerald Ford Class Super-Carriers

Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.

As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.

DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.

E-2D Hawkeye: The Navy’s New AWACS

Northrop Grumman’s E-2C Hawkeye is a carrier-capable “mini-AWACS” aircraft, designed to give long-range warning of incoming aerial threats. Secondary roles include strike command and control, land and maritime surveillance, search and rescue, communications relay, and even civil air traffic control during emergencies. E-2C Hawkeyes began replacing previous Hawkeye versions in 1973. They fly from USN and French carriers, from land bases in the militaries of Egypt, Japan, Mexico, and Taiwan; and in a drug interdiction role for the US Naval Reserve. Over 200 Hawkeyes have been produced.

The $17.5 billion E-2D Advanced Hawkeye program aims to build 75 new aircraft with significant radar, engine, and electronics upgrades in order to deal with a world of stealthier cruise missiles, saturation attacks, and a growing need for ground surveillance as well as aerial scans. It looks a lot like the last generation E-2C Hawkeye 2000 upgrade on the outside – but inside, and even outside to some extent, it’s a whole new aircraft.

Airbus’ A400M Aerial Transport: Delays, Development, and Deployment

Airbus’ A400M is a EUR 20+ billion program that aims to repeat Airbus’ civilian successes in the full size military transport market. A series of smart design decisions were made around capacity (35-37 tonnes/ 38-40 US tons, large enough for survivable armored vehicles), extensive use of modern materials, multi-role capability as a refueling tanker, and a multinational industrial program; all of which leave the aircraft well positioned to take overall market share from Lockheed Martin’s C-130 Hercules. If the USA’s C-17 is allowed to go out of production, the A400M would also have a strong position in the strategic transport market, with only Russian AN-70, IL-76 and AN-124 aircraft as competition.

Airbus’ biggest program issue, by far, has been funding for a project that is more than EUR 7 billion over budget. The next biggest issue is timing, as a combination of A400M delays and Lockheed’s strong push for its C-130J Super Hercules narrow the field for future exports. This DID Spotlight article covers the latest developments, as the A400M Atlas moves into the delivery phase. Will Airbus’ 3rd big issue become its own customers?

India’s Project 75 SSKs: Too Late to Save the Submarine Force?

India’s submarine fleet currently consists of 16 boats: 10 Russian SSK Kilo (Sindhugosh) Class, 4 locally built SSK U209 (Shishumar) Class, a leased nuclear-powered Improved Akula Class SSN from Russia (INS Chakra), and its own INS Arihant SSBN. Most of the Kilos have been modernized, but readiness rates for India’s existing submarine fleet sits below 40%, and the U209s will have trouble lasting much beyond 2015. With Pakistan acquiring modern submarines, and Chinese submarine building exploding, expanding India’s submarine fleet became an obvious national priority.

In 2005, India confirmed that it would buy 6 Franco-Spanish Scorpene diesel submarines, with an option for 6 more and extensive technology transfer agreements. Unfortunately, 7 years after that deal was signed, “Project 75” has yet to field a single submarine. A poor Indian procurement approach, and state-run inefficiency, are pushing the country’s entire submarine force toward an aging crisis. This DID FOCUS article covers the Scorpene deal and its structure, adds key contracts and new developments, and offers insights into the larger naval picture within and beyond India.

Russia Improving its Mi-28 Attack Helicopter Fleet

In August 2012, Russian Lt. Gen. Viktor Bondarev pledged that the state would buy 60 Mi-28UB attack and training helicopters by 2020. That would be good news for the VVS, as well as the Rosvertol plant at Rostov on Don.

Russia is slowly modernizing its military, and its attack helicopter force is one of the areas being given priority. New Ka-52 Alligator and Mi-28N Night Hunter machines are beginning to replace the VVS’ 240 or so old Mi-24 gunships, but training has been an issue for the nascent Mi-28 fleet.
