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.

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.

INS Vikrant: India’s New Carrier

This free-to-view DID Spotlight article offers an in-depth look at India’s troubled attempt to convert and field a full-size aircraft carrier, before time and wear force it to retire its existing naval aviation and ships.

India faced 2 major challenges. One was slipping timelines, which risked leaving them with no aircraft carriers at all. The other challenge involved Vikramaditya’s 3-fold cost increase, as Russia demanded a re-negotiated contract once India was deeper into the commitment trap. The carrier purchase has now become the subject of high level diplomacy, involving a shipyard that can’t even execute on commercial contracts. A revised deal was finally signed in March 2010, even as deliveries of India’s new MiG-29K naval fighters got underway – but now Russia still has to make good. This article tracks the changes India is making to its new aircraft carrier, key characteristics, and a full history of contracts and events affecting this carrier and its planned aircraft contingent.

$1.1B to Upgrade Turkish F-16 fleet

The Turkish and US governments signed a letter of offer and acceptance (LOA) on April 26/05 for the $1.1-billion modernization of 117 Turkish Air Force F-16s to a common avionics configuration. December 2006 saw a $635.1 million contract under that framework issued to Lockeed Martin.

The upgrade will create a common avionics configuration for the service’s fleet of F-16 Block 40 and 50 aircraft. More than 200 F-16 aircraft make up the backbone of Turkey’s current fighter fleet. Systems to be integrated on Turkey’s upgraded F-16s include:

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.

F-X2: Brazil’s Saab Contract for Gripen’s a Done Deal

As Brazil started boosting its defense budgets in past years, its Navy and Army received funds to replace broken-down equipment, while new fighters will be a critical centerpiece of the Forca Aerea Brasileira’s (FAB) efforts.

Boeing’s F/A-18 E/F Super Hornet, France’s Dassault’s Rafale, Saab’s JAS-39 Gripen NG were picked as finalists. But after repeated stalling, for years the question was whether Brazil would actually place an order, or fold up the competition like the ill-fated 2011 F-X process. At the end of 2013, Brazil unexpectedly picked the Swedish offer, thanks to its offsets, price, and lack of diplomatic baggage. An initial contract is now in place, and this Spotlight article takes you through the competition, choices, and ongoing developments in a country that seems likely to become the world’s largest Gripen fleet.

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.

Morocco’s Air Force Reloads: And Now, The Training…

Morocco’s combat air force currently flies 2 squadrons of old F-5 fighters, and 2 squadrons of only slightly newer Mirage F1s. T-37 light jets serve as high-end trainers. Their neighbor and rival Algeria flies MiG-23s of similar vintage, but the Force Aérienne Algérienne also flies SU-24 Fencer and SU-25 Frogfoot strike aircraft, plus even more modern and capable MiG-29s, and is receiving multi-role SU-30MKAs as part of a multi-billion dollar weapons deal with Russia.

Morocco can’t beat that array. Instead, they’re looking for replacement aircraft and upgrades that will prevent complete overmatch, and provide a measure of security. Initially, they looked to France, but key reversals have handed most of this modernization work to the United States.

Australia’s Troubled E-7A “Wedgetail” AWACS Program

The island continent of Australia faces a number of unique security challenges that stem from its geography. The continent may be separated from its neighbors by large expanses of ocean, but it also resides within a potential arc of instability, and has a number of important offshore resource sites to protect. Full awareness of what is going on around them, and the ability to push that awareness well offshore, are critical security requirements.

“Project Wedgetail” had 3 finalists, and the winner was a new variant of Boeing’s 737-700, fitted with an MESA (multirole electronically scanned array) radar from Northrop Grumman. That radar exchanges the traditional AWACS rotating dome for the E-7A’s “top hat” stationary antenna. That design, and the project as a whole, have run into severe turbulence, creating problems for Boeing earnings, the ADF, and other export orders for the type. DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This one covers contracts, events, and key milestones within Australia’s E-7A program, from inception to the current day.

Pakistan & China’s JF-17 Fighter Program

The FC-1/ JF-17 Thunder is a joint Chinese-Pakistani project that aimed to reduce Pakistan’s dependence on western firms for advanced fighters, by fielding a low-cost multi-role lightweight fighter that can host modern electronics and precision-guided weapons. It isn’t a top-tier competitor, but it represents a clear step up from Pakistan’s Chinese MiG-19/21 derivatives and French Mirage III/V fighters. This positioning addresses a budget-conscious, “good enough” performance market segment that the West once dominated, but has nearly abandoned in recent decades.

Pakistan has fielded JF-17s in squadron strength, with more on order and a Block II R&D program nearing completion. India’s competing Tejas fighter is overcoming project delays by looking to foreign component sources, but Pakistan and China remain out front with their offering, even though they began their project much later than India did. Pakistan and China have even set up a joint JF-17 marketing agency to promote export sales, which hasn’t paid off as quickly as they had hoped, but it would be unwise to count them out just yet…
